The purpose of the research was to determine a comparison of COA from non-probability sampling compiled with standard. The research method used quantitative methods by collecting COA data on both ports. These data on the receipt of coal was obtained from a coal-fired steam power plant (PLTU). A Sampling at both ports was conducted by the non-probability sampling method. The assumption was determined that the sample preparation and analysis process had complied with the American Standard Testing and Material (ASTM) standards. The ratio of ash (dry basis) in both COA to its average was processed statistically by taking confidence intervals with a confidence level of 95%. This research showed that the ratio was in the range of 10.213% up to 16.793%, exceeding precision 10% as required by ASTM D2234-16. Therefore, the comparison of COA data from non-probability sampling, could not be used as a reference for the doubt of the work of independent surveyors e.g. COA unloading, then it is technically that umpire test could not be conducted by such comparison.</p> 2020-04-25T00:00:00+00:00 ##submission.copyrightStatement## https://stt-pln.e-journal.id/kilat/article/view/747 Perencanaan Sistem Pengelolaan Sampah Di PT PLN (Persero) Unit Pendidikan Dan Pelatihan 2020-08-10T06:04:51+00:00 Randy Zulkarnain randy.zulkarnain@gmail.com Robby Fiqry Maulana robbyfiqqry@gmail.com Netti Herlina netti@usu.ac.id Lies Setyowati liessetyowati66@gmail.com <p><em>The source of waste produced by PT PLN (Persero) UPDL Tuntungan comes from offices and classrooms, mess and dormitories, parks and roads as well as dining rooms.

In order to develop themselves, they must know what are their strengths and weaknesses. The means to find out the strengths and weaknesses of PLN itself is carried out by individual feedback mechanisms. After participating in the assessment activities, employees will be given the results of the assessment. Notification of the results of the assessment is given verbally which usually includes feedback. In individual feedback, it will be told about what are the strengths, what are the weaknesses and how to reduce the competency gap they have. During this time the way to reduce the competency gap is given directly by the feedbacker. There is one method so that feedbackee (who is given feedback in this case the user who has followed the assessment) is easy to implement how to close the gap, that is, if the way to close the gap is out of the ideas of the asesee themselves, of course with the guidance of the feedbacker who knows the science of how to eliminate the gap competence. The method that matches the above method is the coaching method. The results obtained using the coaching method in the feedback assessment activities become a more effective solution to reduce the competency gap.</em></p> 2020-04-25T00:00:00+00:00 ##submission.copyrightStatement## https://stt-pln.e-journal.id/kilat/article/view/780 Peningkatan Batas Aman Induksi Elektromagnetik Saluran Udara Tegangan Ekstra Tinggi (SUTET) 500 kV Bagi Kesehatan Manusia Berdasarkan Peraturan Menteri ESDM No. 18 Tahun 2015 Juncto No. 2 Tahun 2019 2020-08-10T06:04:43+00:00 Lolita Adhyana Joedo lolita.joedo@gmail.com Ivan Prasetyo Darmawan ivan_pd@pln.co.id <p><em>The Development of Extra High Voltage (EHV) overhead power lines ( SUTET 500 kV) has become a national issue because based on several studies worldwide that shown residents who living next to power lines could increase the risk of their health problems.

The model was a machine series, consisting of electric motor and disc which was connected by 3 Jaw flexible coupling. The shafts were positioned into several axial misalignment conditions to see the effect on the overall vibration value and its component temperature. The result of vibration observation showed that under certain conditions, by increasing shaft misalignment then the overall vibration value tends to decrease. With the decrease of overall vibration value, the machine condition was not in better condition. This was indicated by observing the temperature of the components in this condition, which showed the opposite fact.
