Abstract

The characteristics of  Fiber Bragg Grating (FBG) related to change of reflection power and wavelength shift in the fiber optic due to changes in temperature. Furthermore, the refractive index alo  affects the sensitivity of FBG. Using the Coupled-mode theory, the derivation of mathematical formula can be found to justify the effect of temperature in FBG. Also, the Coupled-mode theory is integrated numerically by the Transfer Matrix method to achieve the final equation of the effect of temperature in FBG. To obtain optimal results, several different parameter values are given to be analyzed. The results show that the temperatures are affecting the wavelength but have no effect on the peak of reflection power. In addition, by increasing the temperature and value of the refractive index will affect the enhancement of the sensitivity of FBG. These characteristics are a good opportunity to produce filters, sensors, or other applications by utilizing the characteristics of temperature in FBG.

Abstract

Transformer life can be reduced due to several things. One of the causes of reduced age is loading. Loading causes an increase in the temperature of the transformer. The aging of this insulation is so fast if the insulation operates in temperatures that exceed the permissible limits, namely at a Hot Spot temperature of 98°C. If a transformer experiences a Hot Spot temperature of 98°C, then its life shrinkage will be so fast that it can reduce the expected life of the transformer. The type of research used is descriptive quantitative research to describe the effects of loading on the transformer. From the results of the study, the percentage of unbalance transformer loads with 100 kVA and 200 kVA TRAFINDO brands did not meet the standards because the percentage value was more than 20%. The results of the analysis of the calculation of life loss and the remaining life of all transformers that are burdened above 80% are still normal or have little effect on the life of the transformer and the estimated remaining life is still above 20 years. So, all transformers operating at PT. PLN (Persero) Rayon Bumiayu is still by the standard.

Abstract

Weigh bridges currently have not played an optimal role. This is because there are still many truck transportation service users who fill vehicles that exceed the allowable limit (overload) and often encounter cases of illegal levies made by unscrupulous policy makers and business actors in order to pass vehicles that do not comply with the rules. The purpose of this research is to design and build a weighbridge system prototype for IoT-based truck load logistics vehicles and to create an automatic proof of violation system for truck drivers or other logistics vehicles with excess loads. The research method used is the Research and Development method. The results of this study are to produce a tool in the form of a weighbridge automatic ticket system prototype using the internet of things that can be integrated with the system owned by policy makers from the central to the regions, and also the system can issue proof of violation notifications to drivers directly without any illegal fees. Based on the results of tests carried out on the prototype using the JBI 35gram assumption, if the measured truck load exceeds 35 grams, it will send a proof of violation notification on the telegram and if appropriate, JBI will send a notification to continue the trip to the driver.

Abstract

Electricity is the energy that is very needed by the society, mainly during the Covid-19 pandemic in now era, people are often stay at home because of PSBB (Large-Scale Social Restrictions), WFH (Work From Home) and online schools. Therefore, PLN is required to maintain the quality of electrical energy that is distributed to the customers. An electric power distribution system can be said to be reliable is if the disturbances and blackouts that occur in a certain period of time are below the specified reliability index number. A measure of the reliability in a system can be stated by calculating the SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index). The electric power distribution system in ULP Sidareja has a SAIFI value of 0,179 times/customer/year and SAIDI value of 0,199 hours/customer/year. The SAIFI and SAIDI value in ULP Sidareja is still below of the standard value which set by the SPLN 68-2-1986 standard, IEEE std 1366-2003 and WCS, furthemore the quality of the electricity distribution system in ULP Sidareja can be categorized as reliable.

Abstract

Tujuan penelitian ini mengetahui pengaruh penambahan kapasitor bank terhadap Perbaikan Daya pada Direct On Line (DOL) berbasis Programmable Logic Controller (PLC) di Motor Listrik 3 Phase. Mayoritas beban di industri memakai beban motor induksi 3 phase yang merupakan beban induktif. Keuntungan motor listrik 3 phase tersebut dan negara yang masih menyubsidi konsumsi listrik. Hal ini merupakan suatu indikasi setiap konsumen dapat melakukan perbaikan faktor daya dengan tujuan efisiensi daya. Penelitian yang digunakan adalah jenis kuantitatif dengan mengeksperimenkan penambahan kapasitor bank pada motor 3 phase. Melalui tahapan perancangan alat, pengujian alat pengambilan data faktor daya & efisiensi, analisis data dan penarikan kesimpulan. Hasil penelitian penggunaan kapasitor bank berpengaruh pada perbaikan faktor daya yang ditunjukkan dari signifikasni 0,001 < 0,05 pada rangkaian DOL di motor listrik 3 fasa berbasis PLC. Diperkuat dengan nilai rata-rata cos phi sesudah penggunaan kapasitor bank memiliki nilai 0,912 yang artinya sudah sesuai standar PLN yaitu nilai 0,9. Cos phi mendekati angka 1 dapat dikatakan penggunaan listrik lebih efisien. Dapat dilihat dari nilai rata-rata efisiensi sebelum dan sesudah yaitu 68,29% menjadi 91,17% artinya mengalami peningkatan.
