Abstract

This research focuses on analyzing power losses due to load imbalance in the medium-voltage distribution network in Pasar Aceh. The aim is to determine the magnitude of power losses that occur at the distribution substation in Pasar Aceh. The research method involves analysis, calculations, and simulations using the ETAP 12.6 software. The results of the analysis indicate that load imbalance in the Pasar Aceh substation leads to power losses. The Trafo Samping Pasar Aceh experiences power losses of 0.77% with a load imbalance of 16.33%. The second transformer in the BNI 46 area incurs power losses of 0.98% with a load imbalance of 30.33%, and the transformer in the BLKG KOTTY area has power losses of 1.17% with a load imbalance of 50.33%. These findings affirm that the greater the load imbalance, the higher the resulting power losses in the electrical distribution network.

Abstract

Early childhood education (PAUD) is very important to prepare an educated generation for the nation and state, and the role of early childhood educators (PAUD) is very important in the development of students. Educators need to go beyond traditional learning by providing learning innovations that utilize information technology, including the ability to master the latest information technology. The focus of the Community Service Program (PKM) is to improve   the quality of human resources (HR) of PAUD organizers in Syiah Kuala District, Banda Aceh Province in the field of information technology, so that they are able to support the management of learning and educational activities. In improving the quality of kindergarten teaching staff in the field of information technology is related to supervision management and making daily learning implementation plans (RPPH). With a system that allows teachers to quickly resolve administrative problems, it is hoped that they can use their time to further develop their knowledge and skills regarding PAUD administrative problems.

The research aims to get the best slope of the solar module to be placed on the roof of the building. This research will look at the performance of solar panels with varying slopes from various types in the city of Banda Aceh. The method used in this research is data collection by looking at the most significant output power from various slopes and comparing it with calculating the output power. The data from each month will also be compared so that the cross panel and the best tilt angle will be. From the research that has been done, it is found that in December and January, with the sun's declination angle of 23 ° and 20 ° North Latitude, the orientation of the solar panel installation is facing south with the best tilt angle of the solar panel is 20 ° -25 ° in December and 18 ° -24 ° in January. In July, the sun's declination is 21.2 ° North Latitude. The orientation of the solar panel installation is facing North, with the best tilt angle of the solar panel being 15 °.

Abstract

A mismatch in the output power of photovoltaic (PV) modules in a PV array can occur due to partial shading or a module replacement. Substitution of a module in a PV array with a new one might lead to different current and voltage characteristics between the new and existing modules and result in power losses. The amount of power loss might be increased more if the PV array experiences partial shading. For this reason, this study aims to investigate the effect of partial shadings on the power output of photovoltaic arrays with different current and voltage characteristics. The PV array under test consists of 25 units of solar modules with a total cross-tied (TCT) configuration. There are five shading conditions applied to the test PV array, i.e., the short narrow (ShN), the short wide (ShW), the long narrow (LnN), the long wide (LnW), and the diagonal. A magic square method is applied to reduce the power loss when the PV modules experience partial shading conditions. The results show that the power loss due to partial shadings, either on all identical modules or partially identical, is the same. The most significant power loss occurs in the long comprehensive shading scenario, where 80% of the modules experience shading, which is 41.30%.

Abstract

Pembangkit tenaga surya terdiri dari komponen solar panel, sistem control, sistem penyimpanan, dan inverter. Tenaga matahari disimpan dalam baterai dan disalurkan ke inverter untuk digunakan oleh beban. Salah satu jenis kimia baterai yang sering digunakan yaitu lithium-ion yang memiliki kapasitas besar namun membutuhkan ruang yang kecil. Baterai lithium sangat berpengaruh dengan suhu, over charge, deep charge, dan over discharge yang menyebabkan umur pemakaian baterai menjadi pendek sehingga harus diganti ketika mencapai batas tertentu. Dibutuhkan sistem manajemen pengisian daya baterai untuk memperpanjang umur baterai. Penelitian ini mengimplementasikan algoritma berbasis sorting pada control pengisian baterai dengan mempertimbangkan suhu, state of charge, dan state of health disertai dengan proteksi over charge, deep charging dan over discharge. Algoritma dikembangkan untuk dapat membaca ketersediaan sinar matahari dan kebutuhan beban sampai waktu diperlukan. Penelitian dilakukan secara simulasi sehingga dapat menjalankan berbagai skenario fluktuasi sinar matahari dan fluktuasi beban. Dengan implementasi algoritma ini diharapkan dapat memanajemen pengisian baterai secara efektif dan efisien serta memperpanjang umur baterai. Hasil pengujian dengan skenario irradiance besar dan beban besar menunjukkan nilai battery cycle sebesar 80 cycle (dengan waktu simulasi 10 hari), skenario pengujian irradiance besar dan beban kecil menunjukkan nilai 40 cycle, skenario irradiance kecil beban besar menunjukkan nilai cycle sebesar 20 cycle, dan skenario pengujian irradiance kecil dan beban kecil pada nilai 15 cycle. Semua baterai memiliki SOC dan cycle yang berbeda. Hasil manajemen menunjukkan bahwa cycle baterai dapat dikurangi secara keseluruhan dengan melakukan prosessorting untuk charging/discharging di setiap cell baterai.

Abstract

Peningkatan emisi CO₂ global dan tingginya konsumsi bahan bakar fosil pada sektor transportasi mendorong pengembangan teknologi kendaraan ramah lingkungan. Penelitian ini bertujuan untuk merancang sistem Fuel Cell sebagai sumber energi alternatif pada mobil listrik guna memenuhi kebutuhan daya kendaraan secara optimal dan berkelanjutan. Objek penelitian menggunakan spesifikasi mobil listrik Nissan Leaf S dengan kebutuhan daya maksimum 110 kW. Jenis fuel cell yang digunakan adalah Proton Exchange Membrane Fuel Cell (PEMFC) yang beroperasi pada suhu 60 - 80°C. Perancangan dilakukan melalui perhitungan parameter listrik stack meliputi tegangan, arus, resistansi internal, serta analisis kebutuhan daya kendaraan pada kondisi jalan mendatar, menanjak, dan menurun. Hasil perhitungan menunjukkan bahwa satu sel menghasilkan tegangan open circuit sebesar 1,17 V dan tegangan kerja 0,8 V. Dengan konfigurasi 505 sel diperoleh tegangan stack sebesar 404 V dan arus 276,23 A sehingga menghasilkan daya maksimum 111,5 kW. Hasil simulasi Matlab Simulink menunjukkan sistem mampu memenuhi kebutuhan daya kendaraan baik pada kondisi normal maupun variasi kemiringan jalan. Penelitian ini membuktikan bahwa desain sistem Fuel Cell yang dirancang layak digunakan sebagai sumber energi alternatif mobil listrik dengan performa yang stabil dan efisien.
