faktor utama mockup test dimana masing-

masing rangkaian utama tersebut

mempunyai bobot penilaian yang berbeda-

beda. Bobot penilaian dari masing-masing

rangkaian utama mockup test adalah sbb:

• Seting dan Kalibrasi alat UT yang

digunakan memiliki bobot 20%.

Each participant is required to

demonstrate their ability to perform the

examination in terms of UT thickness

examination and identify defects. In

addition the assessment also relates to

the ability of the participants in doing

good reporting and correct. All steps of

mockup tests carried out within the

specified time limit. Provide time to

carry out the mockup test a maximum

of 120 minutes per one participant.

Where each participant is obliged to

perform UT of three different types of

specimens. Assessment criteria in the

mockup test is very dependent of the

three main factors mockup test in which

each of the primary step has a

weighting of different assessment.

Assessment weighting of each of the

• Sistem pelaporan memiliki bobot 20%.

Nilai akhir penilaian merupakan akumulasi

dari factor utama diatas. Angka minimal

dari kelulusan adalah 70. Dibawah angka

70 maka peserta akan gagal. Nilai akhir ini

nantinya akan digunakan sebagai acuan

para peserta untuk memetakan

kemampuan personil UT. Lebih jelas

20%.

• Examination of mockup test

specimen has a weight of 60%.

• The reporting system has a weight

of 20%.

The final assessment score is the

accumulation of the main factors

above. The minimum passing score is

70. If the score is below 70 then

participants will fail. This final score will

be used as a reference for participants

to map out the ability of UT personnel.

More details on mapping personnel can

be seen in chapter 10.

9. KELULUSAN 9. Graduation

Kelulusan peserta bergantung dari nilai

akhir test dimana apabila nilai akhir diatas

70 maka peserta dianggap telah lulus dari

mockup test. Kelulusan dibagi menjadi

beberapa kategori dimana kategori inilah

yang digunakan sebagai acuan dalam

pemetaan personil.

Graduation of the final value depends

on the final score which if the final

score above 70 then the participant is

deemed to have graduated from the

mockup test. Graduation is divided into

several categories where the categories

were used as reference in mapping

personnel.

9.1 KETIDAKLULUSAN 9.1 Failure

10 PEMETAAN PERSONIL 10 Mapping Personnel

Tujuan dari pemetaan personil adalah

untuk menilai kemampuan personil UT dari

yang paling baik hingga menengah.

Kemampuan tersebut meliputi kemampuan

melakukan pemeriksaan UT dengan akurat

serta kemampuan personil dalam membuat

laporan dengan benar dan jelas. Apabila

personil telah dipetakan, maka hal ini

berguna kedepannya untuk menentukan

bobot pekerjaan yang akan diberikan

kepada masing-masing personil serta

berguna untuk pemilihan komposisi team

yang akan diberangkatkan berdasarkan

bobot dan urgensi pekerjaan. Dimana

idealnya dalam satu team diharuskan untuk

saling menutupi kekurangannya satu sama

lain. Penilaian dibagi menjadi beberapa

kategori yang menggambarkan

kemampuan personil secara keseluruhan.

Adapun tingkatan kemampuan personil

dikategorikan sesuai dengan yang tertera

pada table berikut:

The purpose of mapping personnel is to

assess the ability of UT personnel from

best to medium. These capabilities

include the ability to perform an

accurate examination of UT and the

ability of workers in making the report

correctly and clearly. If the personnel

have been mapped, then it is useful in

the future to determine the work load

to be given to each personnel as well as

useful for the selection of the

composition of the team who will be

dispatched based on the load and

urgency of work. Ideally in a team are

required to cover each other drawbacks

to each other. Assessment is divided

into several categories that describe the

ability of personnel as a whole. The

level of skills of personnel categorized

as stated in the following table:

KATEGORI PERSONIL

DEFINISI

Kategori (A)

Personil mempunyai kemampuan dalam melakukan pemeriksaan ultrasonic dengan akurat. Dalam hal pelaporan personil juga memiliki kemampuan mengerjakan laporan dengan baik dan benar

Kategori (B) Personil mempunyai kemampuan melakukan pemeriksaan ultrasonic dengan akurat namun kurang baik dalam hal pembuatan laporan.

PERSONNEL CATEGORY

DEFINITION

Category (A) Personnel has the ability to perform accurate ultrasonic examination. In terms of reporting workers also have the ability to do well and correct report

Category (B) Personnel has the ability to perform an ultrasonic inspection with accurate but less well in terms of making the report.

Pemetaan personil juga tidak terbatas dari

kemampuan dan kompetensi namun juga

dalam hal “perilaku”. Perilaku disini

mempunya arti yang cukup luas dimana

dapat diartikan perilaku dalam hal

keselamatan selama bekerja dan perilaku

dalam hal tanggung jawab terhadap

pekerjaan, Bagaimanapun yang dapat

menilai perilaku personil selama ia bekerja

adalah orang yang mengontrol pekerjaan

mereka selama dilapangan yaitu QA/QC

Inspector ataupun coordinator dari

perusahaan tempat pekerja tersebut

bekerja. Sehingga saran dan

pertimbangan dapat dibuat pula

berdasarkan informasi dari kedua pihak

diatas.

Mapping personnel is also not limited to

the capabilities and competencies, but

also in terms of "behavior". The behavior

here has general meaning in which the

behavior can be interpreted in terms of

safety during the work and behavior in

terms of responsibility to the job,

however the person that can assess the

behavior of workers during work is a

person who controls their job over the

field that is QA / QC Inspector, or

coordinator of company where

employees are working. So the

recommendations and considerations can

be made also based on information from

both sides above.
