Bertambahnya pertumbuhan penduduk maka pengguna atau pelanggan energi listrik juga bertambah sehingga dapat berdampak terhadap pembebanan pada setiap transformator distribusi. Apabila pembebanan pada setiap transformator meningkat maka dapat menyebabkan kelebihan beban (overload), ketidakseimbangan beban dan rugi-rugi daya (losses) serta kerusakan terhadap transformator. Oleh sebab itu, untuk menjaga agar transformator distribusi dapat beroperasi dengan baik maka PLN telah menetapkan standar pembebanan pada transformator distribusi yaitu tidak boleh melebihi 80%. Tujuan penelitian ini yaitu untuk melakukan pengukuran pembebanan pada transformator distribusi Gardu LSA 249 dan menganalisis terjadinya rugi-rugi daya yang diakibatkan oleh ketidakseimbangan beban. Pengukuran dilakukan dengan menggunakan clamp meter dan eart tester untuk mendapatkan nilai arus dan tegangan serta nilai tahanan dari grounding. Selanjutnya, dilakukan perhitungan pembebanan transformator, ketidakseimbangan beban, serta rugi-rugi daya pada Penyulang LS5 Gardu LSA 249. Hasilnya, pengukuran dari ketidakseimbangan beban yang terjadi ketika pagi hari sebesar 15 %, siang hari sebesar 26 %, dan malam hari sebesar 22%.

If the load on each transformer increases, it can cause overload, load imbalance and power losses and damage to the transformer. Therefore, to ensure that the distribution transformer can operate properly, PLN has set a standard loading on the distribution transformer, which should not exceed 80%. The purpose of this study is to measure the load on the LSA 249 substation distribution transformer and analyze the occurrence of power losses caused by load imbalances. Measurements are made using a clamp meter and an earth tester to get the current and voltage values as well as the resistance value from grounding. Furthermore, the calculation of transformer loading, load imbalance, and power losses at the LS5 Substation LSA 249 feeder. As a result, the measurement of the load imbalance that occurs in the morning is 15%, during the day is 26%, and at night is 22%.

Penelitian ini dilakukan dalam rangka memperbaiki kualitas tegangan Sistem Distribusi yang dipasok dari Gardu Induk (GI) Marisa. Salah satu Gardu Hubung (GH) di sistem distribusi Marisa ini yakni GH Lemito memilki turun tegangan sampai 19.21%. Penurunan tegangan ini diakibatkan oleh GH Lemito yang suplai dari ujung penyulang LM.03 dalam pengoperasiannya melayani beban yang cukup besar, di samping itu juga penghantar utama yang menghubungkan GI Marisa ke GH Marisa masih memakai penghantar berdimensi yang lebih kecil dibandingkan dengan penghantar di percabangan dan tentunya ini menyalahi prinsip-prinsip konfigurasi pada sistem distribusi tenaga listrik tipe radial. Simulasi aliran daya dengan ETAP 12.6 digunakan dalam menyelesaikan masalah pada penelitian ini. Simulasi dilakukan dalam 4 skenario yakni 3 skenario berupa pelimpahan beban dan 1 skenario up rating penghantar. Berdasarkan hasil simulasi didapatkan bahwa skenario 3 dari alternatif solusi pelimpahan beban adalah skenario yang paling mendekati standar SPLN 1:1995 yaitu 17.8 kV dengan persentase turun tegangan sebesar -10.8%. Oleh karena persentase turun tegangan masih di atas 10% maka skenario 3 pelimpahan beban masih perlu ditambahkan kapasitor bank sebesar 2.75 MVAr. Penambahan kapasitor bank pada skenario 3 pelimpahan beban dari hasil simulasi aliran daya dapat meningkatkan tegangan di GH Lemito menjadi 20.10 kV atau naik sebesar 0.52%.The maximum voltage drop in the Electric Power Distribution System has been set, which is no more than 10% of the nominal voltage. This research was conducted to improve the quality of the distribution system voltage supplied from the Marisa Substation. One of the substations (GH) in the Marisa distribution system, GH Lemito, has a voltage drop of up to 19.21%. This voltage drop is caused by GH Lemito which supplies from the end of the LM.03 feeder in its operation serving a relatively large load, in addition, the principal conductor connecting GI Marisa to GH Marisa still uses a conductor with smaller dimensions compared to the conductor at the branch and of course, This violates the principles of configuration in a radial type electric power distribution system. Power flow simulation with ETAP 12.6 is used to solve the problem in this research. The simulation is carried out in 4 scenarios, namely 3 scenarios in the form of load transfer and 1 scenario of up rating conductor. Based on the simulation results, it is found that scenario 3 of the alternative load transfer solution is the scenario closest to the 1:1995 SPLN standard, which is 17.8 kV with a voltage drop percentage of -10.8%.

Pada perpustakaan Universitas Iskandar Muda, saat ini pencahayaannya masih kurang baik dan belum sesuai dengan Standar Nasional Indonesia (SNI) karena sebelumnya ruang perpustakaan UNIDA berfungsi sebagai ruang belajar namun selanjutnya dialih fungsikan menjadi perpustakaan tanpa mengubah sistem pencahayaannya. Tujuan penelitian ini untuk menganalisis dan mendesain tingkat pencahayaan pada perpustakaan UNIDA sesuai dengan standar SNI. Metode yang digunakan yaitu dengan menggunakan rumus sesuai SNI 03-6575-2001 dan mendesainnya dengan software DIALux Evo v.9.1. Hasilnya, didapatkan bahwa tingkat pencahayaan pada perpustakaan UNIDA sebelumnya sebesar 252 lux, setelah dihitung sesuai dengan SNI maka didapatkan tingkat pencahayaan pada perpustakaan UNIDA menjadi 592 lux. Hasil tersebut membuat sistem pencahayaan pada perpustakaan UNIDA menjadi lebih baik, aman, dan nyaman serta sesuai dengan standar SNI.Good lighting and meeting standards is an aspect that is beneficial to add comfort and security to managers or users in carrying out their activities. Poor lighting can cause managers or users to suffer from headaches, eye fatigue, dry eyes, sore eyes, and complaints in the neck and shoulders when carrying out activities such as reading, writing, working, operating computers, etc. At the Iskandar Muda University library, currently, the lighting is still not good and not by the Indonesian National Standard (SNI) because previously the UNIDA library room functioned as a study room but was later converted into a library without changing the lighting system. This study aimed to analyse and design the lighting level in the UNIDA library by SNI standards. The method used is by using the formula according to SNI 03-6575-2001 and designing it with DIALux Evo v.9.1 software. The result, it was found that the lighting level in the previous UNIDA library was 252 lux, after being calculated according to SNI, the lighting level in the UNIDA library was 592 lux. These results make the lighting system in the UNIDA library better, safer, more comfortable and by SNI standards.","PeriodicalId":292481,"journal":{"name":"Jambura Journal of Electrical and Electronics Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131292682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
