Why Energy??
Energy is critical to organizational operations, potentially one of the biggest costs of the organizations regardless their activities
Energy price can not be controlled by a single organization, neither the government policies and the global economy. The company could only manage their energy utilization to reduce the cost.

The steps:
Seeking for where the greatest energy consumed goes to
Measuring the energy losses of the greatest energy consumer
Analyzing the problem
Establishing a saving strategy
Calculating the saving and payback period
Implementing the strategy
1. Energy Utilization (kWh, Joule),
2. Energy Intensity/ Specific Energy Consumption
(kWh/Ton Prod), (Ton Steam/Ton Prod), (kWh/m2/mth)
(kW/TR), (liter Fuel/Ton Steam), (lumen/watt)
3. Light Intensity (lux) for specific activities
4. Power Intensity (watt/m2, pk/m2)
5. Energy Distribution, Energy Balance, End Use Energy and Energy losses
6. Energy Efficiency and Optimization of Utilities
7. Indoor Air Quality, Room Comfort, and Visual Comfort
8. Energy Saving Potentials (kWh/year, IDR/year)
9. Energy Management Planning and Energy Efficiency Measures

1. Red area, relative humidity above 75%. Are where
virus, bacteria and fungus would increase quickly
2. Yellow, relative humidity between 70-75%. Static
electric would occur especially with carpeted floor.
3. Blue, humidity for conditioned area with good comfort
for human occupancy, suitable for office.
4. Brown, relative humidity < 50%. Too dry which could
cause uncomfortable respiration.

System to monitor and controlling Energy
UtilizationPenggunaan Energi
EMCS (Energy Monitoring & Controlling System) Is digital technology developed to monitor and evaluate and controllong energy utilization according to the need.
EMCS should function as system interface Between different systems. With EMCS a system coul be integrated with other systems to obtain optimum control and monitoring in one control room.
Main function of EMCS can be used as Remote Controller, Alarm, Status Monitoring, Energy Management and System Integrator.
