Abstract

Pembangkit Listrik Tenaga Surya (PLTS) dapat diaplikasikan mulai skala kecil sampai skala besar, itu merupakan keunggulan teknologi ini. Dalam skala kecil, pemanfaatan energi surya dapat diaplikasikan di setiap atap rumah untuk memenuhi kebutuhan listrik tiap konsumen residential / rumah tangga. Untuk kebutuhan ini, sistem PLTS dilakukan secara on – grid yaitu terhubung dengan jaringan yang sudah tersedia yaitu jaringan penyedia layanan listrik seperti PLN. Pada penelitian ini, objek penelitian adalah Gedung X pada Politeknik Negeri Malang, dimana kebutuhan bebannya sebesar 12,5 kW dan kebutuhan energi harian 64 kWh. Menggunakan aplikasi HOMER PRO didapatkan untuk sistem dengan skema PV, Baterai, Grid PLN, dan konverter, maka Skematik yang diusulkan pada sistem PLTS adalah menggunakan solar panel dengan total daya terpasang sebesar 11 kWp, dan ditambah dengan baterai sebesar 1500 Ah, konverter daya sebesar 6 kW , dan grid PLN tetap sebagai suplai utama. Untuk bisa mengurangi tagihan listrik, dilakukanlah Renewable Fraction (RF) sebesar 58,5 %, sehingga didapatkan produksi harian untuk solar panel sebesar 45,6 kWh, yaitu sebesar 68 % kebutuhan harian dengan capacity factor sebesar 17,3 %. Solar panel yang digunakan merk ICASOLAR dengan kapasitas 250 Wp membutuhkan sebanyak 44 panel dengan total luasan yang diperlukan sebesar 57 m2 pada atap gedung. Secara ekonomis didapatkan bahwa Net Present Cost pada sistem ini adalah sebesar Rp. 183.000.000,- dan nilai Cost of Energy sebesar Rp. 484,58,- / kWh ABSTRACT PLTS can be applied from small to large scale, that is the advantage of this technology. On a small scale, the use of solar energy can be applied on every roof of the house to meet the electricity needs of each residential / household consumer. For this need, the PLTS system is carried out on an on-grid basis, which is connected to an already available network, namely a network of electricity service providers such as PLN. In this study, the object of research is Building X at the State Polytechnic of Malang, where the load requirement is 12.5 kW and the daily energy requirement is 64 kWh. Using the HOMER PRO application obtained for systems with PV schemes, Batteries, PLN Grids, and converters, the proposed Schematic for the PLTS system is to use solar panels with a total installed power of 11 kWp, and coupled with a 1500 Ah battery, a power converter of 6 kW , and the PLN grid remains as the main supply. To be able to reduce electricity bills, Renewable Fraction (RF) is carried out by 58.5%, so that the daily production for solar panels is 45.6 kWh, which is 68% of daily needs with a capacity factor of 17.3%. The solar panels used by the ICASOLAR brand with a capacity of 250 Wp require 44 panels with a total required area of 57 m2 on the roof of the building. Economically, it is found that the Net Present Cost in this system is Rp. 183,000,000,- and Cost of Energy amount Rp. 484,58,- / kWh

Abstract

Peningkatan produktivitas pertanian menjadi salah satu tantangan utama dalam mendukung ketahanan pangan di Indonesia. Salah satu cara yang dapat dilakukan untuk mengatasi tantangan tersebut adalah dengan mengintegrasikan teknologi pertanian modern. Pengabdian ini bertujuan untuk meningkatkan produktivitas tanaman melon melalui penerapan sistem smart hidroponik yang terintegrasi dengan Pembangkit Listrik Tenaga Surya (PLTS). Sistem smart hidroponik ini memungkinkan pengelolaan lingkungan tumbuh yang lebih efisien, dengan pengaturan otomatis terhadap kebutuhan air, nutrisi, dan kelembaban, serta pemanfaatan energi terbarukan dari matahari untuk memenuhi kebutuhan listrik. Dengan metode ini satu tanaman melon akan menghasilkan dua buah melon, sebelumnya hanya menghasilkan 1 melon saja. Melalui pengabdian masyarakat ini, petani diperkenalkan dengan teknologi baru yang dapat mengoptimalkan hasil pertanian, mengurangi biaya operasional, dan meningkatkan keberlanjutan pertanian. Hasil yang diperoleh menunjukkan adanya peningkatan produktivitas tanaman melon, serta pengurangan penggunaan sumber daya energi konvensional dan air tanah. Selain itu, penerapan teknologi ini juga berdampak positif pada kualitas tanaman dan pendapatan petani, serta memberikan kontribusi pada pengurangan jejak karbon. Hasil yang diperoleh menunjukkan peningkatan produktivitas tanaman melon serta efisiensi penggunaan air dan energi. Selain itu, teknologi ini berkontribusi pada peningkatan kualitas tanaman, pengurangan biaya operasional, serta peningkatan pendapatan petani mitra di Kabupaten Trenggalek, Jawa Timur.

Abstract

The substation played a vital role in the distribution of electrical power from the generator to end users, requiring a reliable protection system to ensure continuity and safety. At the 150 kV Lengkong Substation, the existing busbar protection system used an electromechanical high impedance relai, which lacked the sensitivity, selectivity, and reliability demanded by current operational standards. This research aimed to improve the reliability of the substation’s protection system by replacing the high impedance relai with a digital low impedance numerical relai (GE P746). The method involved direct field observation, data collection, and system testing, including individual relai tests, functional evaluations, and differential current calculations. Tap settings and wiring integration were adjusted to accommodate the new relai's configuration and performance standards issued by PT PLN (Persero) UIT JBB. The findings showed that the new relai functioned well in normal operation, block trip, and block all modes. The differential current (Idiff) calculations at Busbar 1 and Busbar 2 yielded 9.32 A and 28.25 A respectively—both well below the 80 A protection threshold, indicating system stability and correct operation. These results confirmed that the upgraded relai system operated within the safe zone and did not trigger false trips. This study highlighted the necessity of modernizing protection systems across substations and recommended further integration with digital communication protocols such as IEC 61850 to enhance future grid reliability and responsiveness.

Abstract

Solar power plants are efficient and environmentally friendly sources of renewable energy. Previously, a solar power plant with a capacity of 6 x 100 Wp had been installed at the Al-Ikhlas Orphan Boarding School, Singosari District, Malang Regency, but the power produced was not optimal. Therefore, the addition of solar modules with a capacity of 4 x 100 Wp is carried out. It is necessary to design and analyze solar power plants using pvsyst software to find out how effective the addition of solar panels is so that the total capacity is 10 x 100 Wp. This research includes the design and simulation of solar panels to optimize the system configuration, including the placement of solar panels, tilt angles, and orientation. The analysis is carried out by taking into account location data, equipment specifications, and local environmental conditions. The results of the study show that the design value of solar power plants using PVSYST software is: average annual radiation of 870 kWh/m², temperature value of 24.99°C, PV input power of 1667.2 Watts, output power of 1595.4 Watts, performance ratio of solar power plant 0.809, and efficiency value of 18.8%. After testing in the field, an average efficiency was obtained in sunny weather of 15.47% with an average voltage of 31.62 V, current of 20.03 A, and power of 651.18 Watts. The addition of solar modules significantly improves the energy production and efficiency of solar PV.
