Abstract: Two third of ocean freight industry in Malaysia are classified as small and medium enterprise
(SME) which they are currently struggling to stay in industry caused by the merging of global shipping
alliances. The merging of alliances has impacted the SMEs in terms of competitiveness in getting
business opportunities, where SMEs have to compete alongside established companies with well-known
reputation. Therefore, differentiation is becoming very crucial factor in order to leverage their capabilities.
Without differentiation factor, SMEs are unable to identify their competitive advantages that distinguishes
them from competitors, hence causing difficulties to survive in the industry. Another issue arises is the
absence of a unique Logistics Performance Measurement System (LPMS) that takes into account the
particularities of ocean freight industry, consequently causing slow adaptation of LPMS despite the size
and maturity of this industry. Thus, this research attempts to develop a preliminary logistics performance
measurement system (LPMS) framework for ocean freight industry and incorporates differentiation factor
in the developed LPMS. The preliminary framework is developed based on extensive literatures in
logistics performance measures, and consists of three logistics performance measurement dimensions
(efficiency, effectiveness and differentiation). However, this proposed framework is only a starting point
for integrating the views of logistics operators in the analytical processes.

INTRODUCTION
Realignment of global shipping alliances has taken a toll on Malaysia’s logistics performance, especially
in the ocean shipping industry. Consequently, the overall pool of competitors has become smaller due to
the merger of the shipping conglomerates (Bailey, 2017). The formation of three main alliances has
resulted in bigger monopolies in local ocean shipping environment due to the merger of multinational
companies (MNC) that are berthing in Malaysia, and bigger companies won bigger contracts. This
situation has caused the SMEs to receive less attention in ocean freight selection by importers and
exporters of the country. Other than that, the industry apparently has been very slow on adopting
Performance Measurement System (PMS) despite the size and maturity of their industry, due to the
absence of a unique framework that takes into account the particularities of ocean freight industry (Konsta
& Plomaritou, 2012). Shipping companies are still experimenting with various performance measurement
system (i.e. KPI, Performance Prism, Balanced Scorecard) in the absence of a common, uniform
measurement system that will apply to all sectors of the ocean freight industry (Otheitis & Kunc, 2015).
OBJECTIVE
The objective of this research is to develop a preliminary Logistics Performance Measurement System
(LPMS) framework for small and medium enterprises (SMEs) in ocean freight industry.
LITERATURE REVIEW
Fugate, Mentzer, & Stank (2010) analysed the relationship between logistics performance and
organizational performance, stating that logistics performance is multidimensional and is a function of the
resources used in logistics, according to outlined objectives and outcomes against competitors. In this
context, the authors theorized that analysis of logistics performance should be based on evaluation of a
set of dimensions of the activities carried out by the logistic function, which are namely, efficiency,
effectiveness and differentiation. Efficiency is a factor related to the use of resources allocated to the
logistic function, effectiveness can be defined as the extent to which objectives are achieved and
differentiation is understood as the value that can be generated by the elements of customer service in
relation to competitors.
METHODOLOGY
The preliminary framework is developed based on extensive literatures in logistics performance
measures.

CONCLUSION
In summary, the logistics performance measurement system (LPMS) for small and medium enterprises
(SME) is a response to the need to support those entities in the area of tools which enable effective and
efficient management. The starting point for this study was an analysis of the existing models and
frameworks of LPMS. The LPMS model and its implementation will help to bridge the gap between theory
and practice as well as to spread the significance of LPMS among SMEs in ocean freight industry.

Abstract: A cadastral is an official record of information about land parcels. Cadastral surveying is work
involving determination of boundaries and area of a lot of land or more. There are many techniques that
have been employed for producing map or plan of cadastral boundary around the world. An example of
these techniques are conventional survey, conventional photogrammetry, satellite imagery and
unmanned aerial vehicle (UAV) photogrammetry. Among these techniques, the most common used
technique for cadastral mapping is conventional survey. This technique was used for a long time ago and
can provide very high accurate output, however, it has constraints from the aspect of time consuming
and expensive cost. Rapid development around the world especially in developed countries cause the
changes of techniques for mapping cadastral boundaries. Therefore, mapping the cadastral boundaries
for update purpose needs to be performed regularly or many times. Due to the development of robotic
industry, UAV system which utilised robotic concept and system can be used as a platform for data
acquisition in the field of geospatial and photogrammetry. UAV offers many advantages such as portable,
rapid data acquisition, efficient, low-cost and produces accurate results. All these advantages are
suitable, valuable and significant for cadastral mapping application. Development of UAV has grown very
rapidly where many new types and model of UAV were developed which can use many types of sensor.
This situation encourage the use of UAV in many applications especially for mapping application.
Therefore, this paper reviews the potential of UAV system used in cadastral mapping by examining
related research done around the world and at national level using UAV system for cadastral mapping.
This review will also focus on the quality of final output, methodology used and hopefully it can be used
as a guideline for future work on the implementation of UAV system in cadastral mapping.

INTRODUCTION
Recently, the demand of unmanned aerial vehicle system have increases due to the rapid development
and production of robotic system. Many fields have used UAV as a data acquisition platform to collect
the geospatial data. UAV system have advantages instead of conventional photogrammetry. UAV have
capability to produce a high resolution digital imagery, no cloud cover, rapid data acquisition, low cost
system and able to generate high accuracy photogrammetric product. Cadastral is land information
system. Meanwhile, cadastral survey is the process of determine and measure the position, size and
boundary mark of a piece of land parcel. Cadastral is very important for society and government.
Basically, cadastral is partially of process to register the property of person. Nowadays, cadastral survey
demand the accurate, low cost and faster method to reduce the period of registration the land or property.
Therefore, UAV system seen have potential to fulfil the demand in cadastral survey. However, the
exploration of the system for cadastral survey is still lacking and new especially in Malaysia. Hence, this
paper is to review ability of UAV system to use in cadastral application.
OBJECTIVE
The main objective of this paper is to review the potential of unmanned aerial vehicle system or UAV
used in cadastral application. The capability of UAV used in cadastral application is evaluated and
reviewed from the past publications have been made by researchers around the world related to UAV
and cadastral mapping.
LITERATURE REVIEW
Unmanned aerial vehicle (UAV) can be defined as a system used to capture the aerial
photograph or collect any information on the earth surface with no pilot on broad.
According to (Bailey, 2012), UAV is a motorized aircraft system controlled remotely by
remote control devices or completely autonomous with aid of on-broad system of
navigation and ground control station. UAV can described as a device for collecting
remote sensing data where it allow flexible manoeuvre, produce high resolution image, can
fly under cloud cover, easy to operate, rapid data acquisition and low cost. Due to these
advantages, UAV has been used in various application such as mapping, monitoring,
mining, scientific research, agriculture, archelogy and others. Over last few years,
there are many types of UAV with special sensor such as digital camera that have been
produced by the manufactures around the world. Until today, UAV can carry many sensor
such as Lidar, multispectral, thermal, hyperspectral, compact digital camera and real time
kinematic (RTK) GPS receiver. RTK UAV is the latest systems designed to generate a
very high accurate output ranging to a few centimetres.
Manufacturing of RTK UAV create a chance and potential for UAV system to be
used in application like cadastral mapping. Cadastral is the field that is used to determine
the position, size and boundary mark of piece of land as the property of a person. While,

cadastral surveying work is for the purpose of land ownership and registration in
accordance with Government Regulation. According to Cadastral Rule Survey 2009,
cadastral survey is to produce as issued in the State Land Act 1965, Licensed Land
Surveyors Act 1958 and Regulations of the Land Cadastral Surveying Department. Multipurpose
cadastral is an example of cadastral application. Multi-purpose cadastral can be
defined as cadastral overlay delimiting the current status of the property owner. The
individual building block for the overlay is the cadastral parcel, an unambiguously defined
unit of land within which unique property interest property interests are recognized. The
overlay will consist of a series of maps showing the size, shape and location of all cadastral
parcels within a given jurisdiction. Figure 2 shows an example of cadastral boundary in
Zurich, Switzerland (Manyoky et al., 2012)
Accuracy of final product are very important aspect in this application where every
measurement or survey must follow the standard operating procedure (SOP) has been set
by national surveying department and the final output needs to checked and endorsed.
There are various technique that can be used for application of mapping cadastral boundary
around the world. Among the techniques are conventional survey, conventional aerial
photogrammetry, high resolution satellite imagery and UAV photogrammetry. In Malaysia,
conventional survey is the most common technique used to map the cadastral boundary
from the colonial time until today. Conventional survey such as total station and Global
Navigation Satellite System (GNSS) can produce a very high accuracy in term of
generation the output in the form of points and lines, however they have constraints from
the aspect of time consuming and required expensive cost (Harintaka, Susanto and
Hartono, 2009). Therefore, demand of fast and efficient surveying method caused a new
method or system needs to be explored to support and helps to fulfil that demand. The
system can fulfil that requirement is UAV photogrammetry.
FINDINGS
The findings is UAV has bright potential to be use in cadastral application. Many publication states the
UAV system have advantages over conventional methods in term of costing, time consuming, less man-
power and able to offer additional information rather than conventional methods. Accuracy of final
products is very important aspect in cadastral mapping. Every final product must follow and achieved the
existing standard accuracy stated by National Department of Survey. In this case, UAV system also able
to fulfil that requirement.

CONCLUSION
This review aims to explore the potential use of UAV photogrammetry in mapping
cadastral boundary. Three aspects are discussed in this paper which have relation
between each other. However, these aspects are very important element in cadastral
application and as an indicator to study and analysed the potential use of UAV system
for this application. As a conclusion, UAV system really has great potential to be used in cadastral
mapping due to the advantages offered by the system as compared to conventional method. The national
surveying department could benefited from UAV photogrammetry for producing rapid, fast, low cost and
accurate cadastral map.

__________________________________________________________________________________
Abstract: This paper proposed a deterministic approach to develop preliminary operation plan for a
hydro reservoir with limited inflow data and then assessed its performance. Two key parameters,
namely expected reservoir yield and target reservoir elevation that are required to decide the planned
reservoir release for the predetermined planning horizon were identified for the hydro reservoir. Due to
the lack of quality data to acquire and/or back-calculate inflow, the expected reservoir yield was
estimated based on design data. Subsequently, target reservoir elevation was obtained based on
simulation. From simulation, key performance indicators namely potential energy utilization index,
average gross head, average reservoir elevation, production volume, spillage volume and percentage
were assessed too. By comparing the simulation results between proposed method and actual
condition, it was found that the proposed method produces 7812 J/m3 (3.04%) higher potential energy
utilization index, 0.037 m (0.14%) higher average gross head, 0.175 m (0.12%) higher average
reservoir elevation, 8.041 x 109 m3 (37.16%) higher production volume, 6.092 x 108 m3 (88.93%) lower
spillage volume, 2.81% (91.70%) lower spillage.

INTRODUCTION
Hydropower is a proven and thus popular renewable energy source. While human’s thirst for energy
continues to grow, getting the most value from all energy sources including this reliable yet flexible one
is becoming more important.
Hydro optimization is a wide research area. It includes reservoir operation planning and management whereby the amount and time of reservoir water release, as well as its target water level, were decided for each planning or scheduling period. Another component is economic load dispatch in which number of operating turbine-generator units, unit selection and their respective generation were decided in real time. Optimizing the performance of turbine-generator units in the hydro power plant through effective and efficient maintenance at appropriate timing through predictive analytics or other approaches is only a subarea.
This paper focuses on reservoir operation planning for a reservoir that is located downstream of the main flood control reservoir in a cascaded hydro system. As its role in flood control is less significant, inflow was not measured and the back-calculated inflow (based on generation and water level) was also not available in the quality and size fit for inflow forecasting. For this reason, design data of the reservoir, which are often the result of hydrological investigation for sufficiently long period, is more suitable and thus used for inflow estimation.
OBJECTIVES
To develop a preliminary and ready-to-use reservoir operation plan for a hydro reservoir lacking quality
inflow data based on design data and simulation
LITERATURE REVIEW
Reservoir operation optimization problem are computationally hard to solve considering the uncertainty
associated with inflows, possibility of having multi objectives and inclusion of nonlinear functions such
as hydropower generation, evaporation and other losses (Rani and Moreira, 2010).
There are two main methods in reservoir system optimization, namely deterministic and stochastic. In
deterministic methods, a single set of fixed boundary conditions (flows and demands) and results are
considered. On the other hand, stochastic formulations require explicit representation of probabilistic
inputs, parameters and outputs. Nevertheless, deterministic models can become probabilistic when run
many times using different inputs based on representative hydrology from synthetic stream flow
generator or historical records and report results spanning a broad range of conditions (e.g. Monte-
Carlo simulation and implicit stochastic optimization) (Harou et al., 2009, Rani and Moreira, 2010). Rani
and Moreira (2010) also summarize the pros and cons of both methods. As summarized, deterministic
methods are better than stochastic methods as they can be formulated to represent a problem more
closely. However, stochastic methods fare better in dealing with extreme operating conditions such as
severe flood or drought. Overall, stochastic methods are more appealing but it requires great
computational effort regardless of using classical optimization techniques (e.g. linear programming,

nonlinear programming and dynamic programming) or artificial intelligence based techniques (e.g.
evolutionary algorithms, fuzzy set theory and artificial neural networks).
To minimize the computational effort, Othman (2002) proposed and implemented TNBR’s deterministic
method for optimization of water release successfully for Temengor reservoir in Sungai Perak
Cascaded Hydro Scheme.
METHODOLOGY
TNBR’s deterministic method for optimization of water release (Othman, 2002) was applied to Bersia
reservoir, which is located downstream of Temengor reservoir in Sungai Perak Cascaded Hydro
Scheme. This method can be expressed as follows:
Objective function: Maximize Potential Energy Utilization (PEU) Index as shown below.
𝐏𝐄𝐔 =𝛒 × 𝐠 × 𝐕𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧×𝐇𝐠𝐫𝐨𝐬𝐬
𝐕𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧+𝐕𝐬𝐩𝐢𝐥𝐥 (1)
where
= water density of the reservoir = 997 kg/m3 g = gravitational acceleration at the site = 9.781 m/s2 Vproduction = production volume (m3) Hgross = gross head of the hydro power plant (m) Vspill = spillage volume (m3)
As shown in (1), PEU index can be maximized by optimizing Vproduction and maximizing Hgross.
The production volume can be expressed as shown below.
𝐕𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 = 𝐕𝐲𝐢𝐞𝐥𝐝 + ∫ 𝐀𝐱 𝐝𝐱𝐱@𝐭=𝐟
𝐱@𝐭=𝟎 (2)
where Vyield = expected reservoir yield (calculated based on design data)
∫ 𝐀𝐱 𝐝𝐱𝐱@𝐭=𝐟
𝐱@𝐭=𝟎 = storage change to achieve target reservoir elevation
The expected reservoir yield was calculated from design annual average energy production considering design overall efficiency, water density of the reservoir, local gravitational acceleration and rated gross head.
The gross head can be expressed as shown below.
𝑯𝐠𝐫𝐨𝐬𝐬 = 𝑭𝑩𝑬 –𝑻𝑾𝑳 (3)
where
FBE = fore bay elevation
TWL = tailrace water level
Since tailrace water level is a dependent variable that is proportional to turbine discharge, maximizing gross head literally means maximizing fore bay elevation, subjected to design limits of the reservoir.

To employ this method for maximization of PEU index, a simulation model was developed. By fixing target reservoir elevation (i.e. fore bay elevation) to find out the required storage change and using expected reservoir yield to compare against actual inflow, the resultant production volume and final reservoir elevation for each time step were calculated and passed to the next time step for 8 years from 1 September 2008 to 31 August 2016. At the end of the simulation, key performance indicators, namely potential energy utilization index, average gross head, average reservoir elevation, production volume, spillage volume and percentage were assessed. This process was repeated by varying target reservoir elevation. Finally, the optimal target reservoir elevation, which gives the maximum PEU index, was found. For comparison, the key performance indicators were also assessed based on actual reservoir conditions for the same time period.
FINDINGS
Table 1 shows the results of simulation for optimal and actual conditions and comparison between them.

CONCLUSION
A preliminary reservoir operation plan for a downstream reservoir of a cascaded hydro system has been developed based on design data and simulation using TNBR’s deterministic method for optimization of water release. Based on the results of simulation for 8 years data from September 2008 to August 2016 between the proposed reservoir operation plan (optimal) and actual reservoir operation condition, it was found that the optimal plan yields better performance in all aspects, particularly PEU index and spillage volume or percentage.

Abstract: This work deals with the use of ZnS-coated TiO2 films as photoanode in a dye-sensitized solar
cell (DSSC). The effect of immersion time of ZnS precursor on the photovoltaic parameters of the device
has been investigated. The immersion time has been varied from 30 to 90 minutes at 15 minutes interval.
The sample prepared with 60 minutes of immersion time shows the highest optical reflection in the visible
region while the sample prepared with 45 minutes of immersion time possesses the highest optical
absorption in the UV region. The DSSC utilizing the photoanode prepared with 60 minutes of immersion
time demonstrated the highest η of 0.80%, Jsc of 2.990 mA cm-2, Voc of 0.650 V and FF of 0.412. This is
due to this device has the smallest charge transfer resistance at the interface of Pt/electrolyte (Rct1) of
0.480 Ω.
Keywords: dye-sensitized solar cells, photoanode, ZnS-coated TiO2
INTRODUCTION
The performance of dye-sensitized solar cell can be improved by utilizing modified metal oxide
photoanode. The photoanode can be modified via several ways, namely, coating photoanode with
another metal oxide, introducing composite struture consisting of two metal oxides and doping metal
oxide with metal or metal. In this work, TiO2 films have been coated with ZnS and then utilized as a
photoanode of the device.

The objective of this work is to investigate the effect of immersion time of ZnS precursor that is zinc nitrate
hexahydrate on the optical properties of ZnS-coated TiO2. The next objective is to study the effect of
immersion time of zinc nitrate hexahydrate on the photovoltaic parameters of the device has been
investigated.
LITERATURE REVIEW
Hu and his group reported that the recombination of electrons with holes was depressed by introducing
strontium oxide (SrO) shell coating on TiO2 and consequently increased the power conversion efficiency
of the device [2]. Zhu and his co-workers found that the efficiency of the device was improved upon
utilizing graphene-TiO2 composite photoanode due to the increase in photocurrent density and voltage
[3]. Dong and his co-researchers employed silver-loaded TiO2 composite as a photoanode of DSSC and
found a significant increase in the efficiency of the device [4]. TiO2-coated ZnO has been applied as
photoanode of DSSC and demonstrated the power efficiency of 5.65% [5]. TiO2-coated ZrO2 has been
employed as a photoanode of the device and the short-current density (Jsc) has been improved by two
times compared with the device utilizing TiO2 potoanode [6]. The DSSC employing TiO2-coated Nb2O5
demonstrated the efficiency of 7.23% due to the significant increase in the short-circuit current density
[7].
METHODOLOGY
TiO2 films were grown twice on ITO substrates via liquid-phase deposition technique [8]. The ITO
substrates were immersed in a solution containing 0.2 M boric acid, H3BO3 and 0.1 M ammonium
hexafluorotitanate, (NH4)2TiF6 for 25 h. The growth temperature was maintained at 30 °C. After 25 h, the
TiO2 samples were left to dry. ZnS solution was prepared separately by dissolving zinc nitrate
hexahydrate and thiourea in ethanol with molarity ratio of 1:1. Then, the TiO2 Samples were immersed in
0.01 M ZnS solution for 30 min. Finally, the sample was annealed at 400 °C for 1 h. These procedures
were repeated for preparing ZnS-coated TiO2 with other precursor immersion times, namely, 45, 60, 75,
and 90 minutes. The samples were characterized by UV–Vis to study its optical absorption and reflection.
0.5 mM of N719 dye solution was prepared as the photoanode sensitizer. ZnS-coated TiO2 films were
immersed in the dye solution for 15 h at room temperature. The counter electrode of the device was
platinum film grown on FTO substrates. Redox electrolyte containing iodide/triiodide was injected into the
space between TiO2/ ZnS-coated N719 and platinum counter electrode. The devices with an active area
of 0.23 cm2 were tested in dark and under the illumination of 100 mW cm−2 light. The light source used
was tungsten halogen lamp. The electrochemical impedance spectroscopy (EIS) was performed on the
devices to determine the charge transport properties and carrier lifetime.

FINDINGS
The use of ZnS-coated TiO2 has been found to improve the performance of the DSSC. The performance
of the device is significantly influenced by the immersion time of zinc nitrate hexahydrate.
CONCLUSIONS
The ZnS-coated TiO2 has succesfully been prepared via liquid phase depostion technique assisted spin
coating technique and employed as photoanode of DSSC. The device utilizing the photoanode prepared
with 60 minutes of immersion time demonstrated the highest η of 0.80% and Jsc of 2.990 mA. This is due
to this device has the smallest charge transfer resistance at the interface of Pt/electrolyte (Rct1) of 0.480
Ω.

Abstract: Burglary means gaining an unauthorised access into others building or premises with intent
to steal goods. It can be done by using shere force to break into the house, using false keys or other
ways. Most residential breaks-in occured by targeting single family houses as its most frequent targets.
Normally, these breaks-in does not result in conforntation or injuries with the people who reside in the
house as most breaks-in occur when the resident is out of the house. But in uncommon cases, some
burglar will enter the premises when it is occupied and will threaten them with violence. Nowadays
house buglary cases had risen in a wary ways. These problem can be solve in an effective method
which is to use an automated home secutrity system. House security system become the most efficient
solution to overcome the house intrusion problem which are happening quite often this day. As we
know, most security house system are expensive and difficult to use. Therefor many people choose to
neglect the implementation of a house security system in their house. For that particular reason, an
effective smart house security system at low cost is build where user can also program the security
system on their own. The project consists of several components namely the Arduino board as a
microcontroller, the ESP8266 module as a Wi-Fi module, an Infra-Red (IR) sensor, vibration sensor and
force sensor as a device to detect intrusion and the light emitting diode as a signal for any intrusion. In
this project the sensors will detect for any kind of intrusion and then will alert the user via a smartphone
application. In addition, all the data from the sensors will be stored in a cloud application called
ThingSpeak. Consequently, users can monitor the house from everywhere via their mobile application..

INTRODUCTION
Burglary means gaining an unauthorised access into others building or premises with intent to steal
goods. It can be done by using shere force to break into the house, using false keys or other ways.
Most residential breaks-in occured by targeting single family houses as its most frequent targets.
Normally, these breaks-in does not result in conforntation or injuries with the people who reside in the
house as most breaks-in occur when the resident is out of the house. But in uncommon cases, some
burglar will enter the premises when it is occupied and will threaten them with violence. This project is
focusing on developing a smart house security system.
OBJECTIVES
The main aim of this project is to design and develop a smart house security system with the
implementation of Arduino Uno. There are several main objectives of this project in order to achieve the
aims, which are:
I. To create a system that can detect any home intrusion with the use of various kind of sensors
II. To create a code that is able to capture input from sensors to be processed by Arduino Uno
III. To deploy a home monitoring system that can be done by using smartphone
LITERATURE REVIEW
According to the Malaysian federal police Crime Prevention and Community Safety Department, a total
of 38,877 crimes involving properties were recorded in the first quater of 2016 and a total of 6662 cases
involving house breaks-in [1]. Fully gated residential area with a 24-hours guards monitoring the area
did help to prevent the breaks-in from happening. Netherless, it still didn’t fully help to prevent and solve
the breaks-in from occuring. This because the security that implemented still have human-error that
cannot be altered. So as the solution for this problem is to apply a fully automated home security
system that can monitor and alert the resident for breaks-in.
Nowadays, house security system become the most efficient solution to overcome the house intrusion
problem which are happening quite often this day. As we know, most security house system are
expensive and difficult to use. Therefor many people choose to neglect the implementation of a house
security system in their house. For that particular reason, an effective smart house security system at
low cost is build where user can also program the security system on their own. Automation is a
scientific and technological ways of manufacture of machine where its take over most work that was
done by humans. The manual security provided to property of individuals is cost more in term of money

and labor. In addition of human errors also may affect the whole security system and a single mistake
may fail the whole system. Hence automation in security purpose is necessary.
METHODOLOGY
This project is focusing on developing a smart house security system with an active infrared motion
detector, pressure sensor and vibration sensor which are controlled by using Arduino Uno. Then all the
information that were identified by sensors, is informed to web server and then to mobile apps. This
information is sent to central web-server using Wi-Fi network in real time, and user can know about the
security of their house from anywhere whether they are at home or not. The overall project is divided
into two main part. The first part which concern on hardware development. While, the second part is
mostly about the programming of software to operate the hardware structure. As the result of both main
part, the infrared detector, pressure sensor and light sensor are capable of detecting motion and in the
same time the programmed Arduino Uno is capable to control the whole operation of the security
system.
FINDINGS
The experimental result did meet expected result. The system work in desired condition and running
smoothly. Several debugging had been made to the hardware and software so that they meet with the
expected result.
CONCLUSION
This smart house security system is hoped to fulfill all the host’s demand and make the home as safe and comfortable as possible. With this system, the security of the house can be increase and be more efficient. With the addition of mobile apps that can keep the user an up to date information about their house’s security, user can be more calm and comfortable to leave their house for a period of time.Farmer, education and research are often stressed because it is important to realize that there are many more actors in the food chain that directly influence decision making of farmers and their innovations.
