Abstract

Gedung ICT Universitas Diponegoro merupakan gedung yang difungsikan sebagai gedung perkantoran bagi Lembaga Pengembangan & Penjaminan Mutu Pendidikan (LP2MP) dan Lembaga Penelitian dan Pengabdian Kepada Masyarakat(LPPM).Dengan data hasil pen gukuran yang dilakukan menggunakan Power Quality Analyzer dan tangampere, maka didapatkan adanya ketidakseimbangan beban. Salah satu tanda ketidakseimbangan beban adalah adanya arus netral. Pengukuran pada SDP lantai 1 diketahui arus netral sebesar 5,8 A. Oleh karena itu dilakukan analisis mengenai keseimbangan beban di Gedung ICT Universitas Diponegoro menggunakan software bantu ETAP 12.6 dan evaluasi Circuit Breaker sebagai perlatan proteksi demi terciptanya keamanan dan kenyamanan. Berdasarkan hasil perhitungan dan simulasi ETAP 12.6  maka didapatkan nilai arus netral pada SDP Lantai 1 sebesar 0,7 A, selain itu Circuit breaker yang terpasang masih berfungsi dengan baik.

Abstract

Penggunaan energi fosil yang terus menerus menyebabkan ketersediannya makin langka, sehingga dibutuhkan sumber energi terbarukan yang bersih dan ramah lingkungan, salah satunya energi matahari. Agar daya yang dihasilkan oleh fotovoltaik maksimal maka diperlukan MPPT. Sistem kendali MPPT akan mengatur produksi dan penyimpanan daya sistem fotovoltaik memanfaatkan DC-DC boost converter. Tugas Akhir ini bertujuan untuk mendesain dan mensimulasikan PLTS dengan MPPT metode Perturb and Observe menggunakan software Matlab Simulink. Pengujian dilakukan dengan variasi iradiasi 200 W/m2, iradiasi 350 W/m2, iradiasi 500 W/m2, iradiasi 650 W/m2, iradiasi 800 W/m2, dan iradiasi 1000 W/m2 serta variasi suhu 22℃, 24℃, 25℃, 26℃, 27℃, 29℃. Hasil pengujian menunjukan, saat iradiasi 350 W/m2 dan suhu 24°C panel surya tanpa menggunakan MPPT menghasilkan daya sebesar 1038 W sedangkan dengan menggunakan MPPT  menghasilkan daya sebesar 1628 W. Saat iradiasi 800 W/m2 dan suhu 27°C panel surya tanpa menggunakan MPPT menghasilkan daya sebesar 2312 W sedangkan dengan menggunakan MPPT menghasilkan daya sebesar 3705 W. Sehingga dengan menggunakan algoritma MPPT Perturb and Observe daya yang dihasilkan lebih maksimal.

Abstract

Indonesia berada di wilayah khatulistiwa sehingga memiliki potensi energi surya yang dapat dimanfaatkan untuk Pembangkit Listrik Tenaga Surya (PLTS). Menurut Power Data Acces Viewer NASA pada tahun 2019 Gedung ICT Universitas Diponegoro mempunyai tingkat radiasi rata-rata yang relatif tinggi yaitu sebesar 5,52 kWh/m2/hari, sehingga dapat memanfaatkan area rooftop dan area parkir terbuka menjadi siteplan PLTS. PLTS ini menggunakan sistem Hybrid yang mengandalkan energi matahari sebagai sumber utama dan baterai sebagai cadangan. Selain itu juga terdapat Automatic Transfer Switch (ATS) yang dapat menghubungkan ke jaringan PLN jika baterai dalam kondisi limit. Melalui software PVSyst 7.0, dengan komponen yang terdiri dari 132 modul berkapasitas 310 Wp/modul, 144 baterai dengan kapasitas 12v200 Ah/baterai, 1 unit inverter 50 kW dan 4 unit SCC 100 A/unit, energi listrik yang dihasilkan sebesar 91,5 MWh setiap tahunnya. Setelah melalui proses konversi energi listrik berkurang menjadi 65,383 MWh dengan  pembagian 57,181 MWh mensuplai beban dan 8,202 MWh dikirim ke baterai sebagain cadangan dengan effisiensi sebesar 68,5%.

Abstract

The increasing demand for electricity demanded that the power distribution system has a good reliability. To improve the reliability of electric power systems, PT. PLN Area Semarang use Recloser on the electricity network. Nowadays, the determination of recloser position is very important in reliability of electrical power system. Reliability index used in distribution systems are SAIFI and SAIDI. The value of SAIFI and SAIDI can be calculated from the outage time and the failure rate occurred in one year. Reliability can be concluded better if SAIFI and SAIDI smaller. This research aims to determine the optimal placement of recloser location on the electrical network in feeder PDP 03 Pudak Payung substation. The method used for the recloser location placement is Ant Colony Optimization (ACO) using Matlab Software R2014a. From simulation result, it can be concluded that the reliability value before and after placement recloser changed. SAIFI and SAIDI before recloser placement is 1.0172 times/year and 2.5435 hours/year. Optimal placement location for 1 recloser is at a location 4 with a value of SAIFI and SAIDI is 0.3361 times/year and 1.0456 hours/year. While for 2 reclosers is at a location 2 and 7 with a value of SAIFI and SAIDI is 0.26755 times/year and 0.86069 hours/year.

Abstract

Abstract:  In today's rapid development, application technology has begun to be widely used in business transactions. The use of computers on mobile devices such as mobile phones is no longer every day; it is even used to order daily necessities through the marketplace. The existence of various types of applications makes us sometimes become unfocused. The research here aims to create a vehicle maintenance application that helps remind users, although many other applications exist. The built-in reminder feature relates to the vehicle maintenance date based on car usage, car age, and the last maintenance date recorded on the application. The research method used is prototyping. Figma adjusted user expectations to current programming needs in developing the initial application design. After the user's expectations are in line, use Android Studio as the Integrated Development Environment for full application development. The results of this study are the functions of the application can be used properly and can remind users to service their vehicles properly.Abstrak: Pada perkembangan zaman yang pesat saat ini, teknologi aplikasi mulai banyak digunakan di dalam transaksi bisnis.

Abstract

The continuity of the supply of electric power is becoming a greater demand from consumers. Feeder MRA05 GI Mrica Banjarnegara supplies electrical energy for parts of Banjarnegara Regency until 2020 has 4 distributed generations, namely PLTMH Sigebang 500 KW, PLTMH Kincang 320 KW, PLTMH Adipasir 320 KW, PLTMH Rakit 500 KW. Based on recorded data in 2020, the MRA05 feeder experienced 15 blackouts/year, with a total outage duration of 38.68 hours/year, of course it was enough to disrupt the continuity of the distribution of electrical energy to consumers. This research discusses the magnitude of the reliability index (SAIFI, SAIDI, CAIDI) when the DG is not installed and installed. The calculation of the magnitude of the reliability index was carried out using the Reliability Index Assessment (RIA) method, the calculation results were compared with the results of the ETAP 12.6.0 software simulation. The reliability index is based on the RIA method when DG is not installed, the SAIFI value is 2.96228 interruptions/year, the SAIDI value is 9.1185 hours/year, the CAIDI value is 3.078 hours/interruption, When DG is installed, the SAIFI value is 2.96228 disturbances/ year, the SAIDI value is 7.567 hours/year, the CAIDI value is 2.5546 hours/interruption.

Abstract

A break in one of the circuits in a double circuit transmission network system can cause the system to overload. Where excess load on the transmission network system can cause quite dangerous impacts. The Over Load Shedding system is a protection system for the electric power transmission network which aims to prevent widespread blackouts by removing certain predetermined loads. By using the Arduino Mega 2560 as a control center, security against load abnormalities can be carried out and can be monitored automatically using Scada, apart from that, PMT taping for load balancing can also be done using Scada. The Arduino Mega 2560 will read the current on each phase wire using the ACS712 current sensor to detect the load of one of the circuits to be aware of whether it is overloaded or not. This simulator tool has carried out several measurements and tested how to operate it. This tool has a fairly high level of work accuracy, reaching 85% success in operation. So it is hoped that this tool can provide knowledge to the wider community about over load shedding systems in maintaining the electric power transmission system properly and easily to understand.
