Abstract

Pemanfaatan energi surya merupakan salah satu solusi strategis dalam meningkatkan kemandirian energi dan kualitas fasilitas umum di wilayah pedesaan. Desa Began, Kecamatan Glagah, Kabupaten Lamongan, Jawa Timur, memiliki potensi energi surya yang cukup besar, namun pemanfaatan dan pemeliharaan sistem pembangkit listrik tenaga surya (PLTS) masih menghadapi keterbatasan pengetahuan dan keterampilan masyarakat. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas masyarakat dalam penggunaan dan pemeliharaan PLTS, khususnya PLTS Penerangan Jalan Umum (PJU), melalui pelatihan dan pendampingan teknis. Metode pelaksanaan meliputi survei awal pada fasilitas desa, yaitu masjid, jalan desa, dan area pemakaman, untuk menentukan lokasi penempatan yang tepat, dilanjutkan dengan pelatihan penggunaan dan pemeliharaan PLTS yang dilengkapi dengan pretest dan posttest sebagai instrumen evaluasi. Selain itu, masyarakat dibekali dengan buku saku sebagai panduan praktis penggunaan, pemeliharaan, dan penanganan gangguan (troubleshooting). Hasil kegiatan menunjukkan adanya peningkatan pemahaman dan antusiasme masyarakat terhadap pemanfaatan energi surya, yang tercermin dari peningkatan hasil posttest serta partisipasi aktif peserta selama pelatihan. Kegiatan ini diakhiri dengan serah terima PLTS PJU dan buku saku kepada masyarakat Desa Began sebagai luaran nyata kegiatan pengabdian. Secara keseluruhan, kegiatan ini berkontribusi terhadap pencapaian SDG 7 (Energi Bersih dan Terjangkau),dan SDG 11 (Kota dan Permukiman Berkelanjutan) melalui peningkatan kemandirian energi dan kapasitas masyarakat desa.

Abstract

Conventional clove drying still depends on weather conditions, making the drying duration difficult to control. This study aimed to design a greenhouse-based clove dryer powered by a Solar Power Generation System (PLTS) with temperature control using an ESP32 and to evaluate its performance compared with conventional drying. The system employed a DHT22 sensor, heater, circulation fan, exhaust fan, automatic sieve rack mechanism, PZEM-017, and ThingSpeak for Internet of Things (IoT)-based monitoring. Testing was conducted using 5 kg of fresh cloves with an initial moisture content of 70%. The results showed that the dryer reduced the moisture content to 12.5% within 32 hours or 3 days, while conventional drying required 40 hours or 4 days and resulted in a final moisture content of 12.9%. The proposed dryer reduced the drying time by approximately 20% and achieved the target moisture content, although temperature stability and heat distribution still require further optimization.

Abstract

This research addresses the limited electrical lighting on rice-field pathways in Munggugianti Village, Gresik, which creates safety risks for residents and farmers at night. The study aims to design and implement an off-grid wind-powered public street lighting system and evaluate its energy efficiency using a cascading control method. A quantitative experimental approach was applied using an ESP32 microcontroller, a four-blade Savonius wind turbine coupled to a 60 W DC generator, six HC-SR501 PIR sensors, and PZEM-017 electrical sensors. Electrical parameters were monitored in real time through ThingSpeak, while field measurements were conducted over 24-hour cycles for seven days. The system harvested energy under wind speeds from 0.9 to 4.2 m/s and achieved a peak charging power of 11.75 W. The ESP32 control successfully activated the lamps sequentially according to detected motion, with a reported precision of 100%. The cascading mode reduced the load from a peak of 62.04 W during full-on operation to 1.69–5.08 W and reached 0 W when no movement was detected late at night. These results indicate that integrating the Savonius turbine with intelligent cascading control can improve energy utilization in off-grid pathway lighting.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun sistem Pembangkit Listrik Tenaga Surya (PLTS) sebagai sumber daya cadangan berbasis Automatic Transfer Switch (ATS) untuk mengamankan proses penyimpanan data komputer kantor saat terjadi pemadaman listrik dari PLN. Sistem yang dirancang terdiri atas panel surya, baterai, Solar Charge Controller (SCC), inverter, ATS, relay, serta beban berupa komputer kantor. Mekanisme ATS diterapkan untuk melakukan perpindahan sumber daya secara otomatis dari jaringan PLN ke sistem PLTS ketika terjadi pemadaman, sehingga kontinuitas suplai listrik tetap terjaga tanpa memerlukan pengoperasian secara manual. Pengujian dilakukan terhadap performa panel surya, waktu perpindahan sumber daya, lama backup, serta perbandingan kinerja PLTS dengan genset sebagai sumber daya cadangan. Hasil pengujian menunjukkan bahwa tegangan keluaran panel surya berada pada rentang 26,8–35,6 V, dengan daya maksimum mencapai 180,2 W pada pukul 12.00 WIB. Sistem ATS mampu melakukan perpindahan sumber daya dari PLN ke PLTS dengan jeda suplai sebesar 7–16 ms, sedangkan perpindahan menggunakan genset memerlukan waktu 8,5–15,2 detik. Lama backup sistem PLTS berkisar antara 1,17–1,19 jam, sedangkan genset mampu memberikan backup selama 1,20–1,30 jam. Selain itu, penggunaan PLTS tidak menghasilkan kebisingan maupun emisi, berbeda dengan genset yang menghasilkan tingkat kebisingan sebesar 82,8–88,6 dB selama pengoperasian. Berdasarkan hasil pengujian tersebut, sistem PLTS berbasis ATS mampu menjaga kontinuitas suplai listrik sehingga proses penyimpanan data pada komputer kantor tetap berlangsung dengan aman saat terjadi pemadaman PLN. Sistem yang dikembangkan juga memberikan solusi sumber daya cadangan yang lebih ramah lingkungan, efisien, dan layak diterapkan pada lingkungan perkantoran.

Abstract

Small-scale electric boats face highly restricted energy margins due to limited battery capacities, whereas a single fishing cycle typically lasts up to eight hours. In operational contexts, the state of charge (SoC) acts as the primary decision variable in the Energy Management System (EMS), making the overall system accuracy heavily dependent on the precision of SoC estimation. For LiFePO4 batteries, the highly flat open-circuit voltage (OCV) curve in the middle SoC range causes conventional estimation methods to lose their sensitivity. This study proposes an integrated simulation model for a 3 GT electric fishing boat, combining a 48 V 200 Ah LiFePO4 battery pack using an OCV-resistance-RC approach, an 860 Wp photovoltaic array, and a 10 kW Brushless DC (BLDC) motor. This modeling generates an eight-hour mission dataset at a one-minute resolution, comprising 60 voyage variations equivalent to 28,800 samples. Random Forest and Long Short-Term Memory (LSTM) algorithms are evaluated using data leakage-free feature engineering that relies solely on measured quantities from the battery management system, excluding cumulative current integration. Based on 5,052 test samples, the LSTM method achieves superior accuracy with an RMSE of 0.587 and an R2 of 0.9970, outperforming Random Forest, which yields an RMSE of 0.696 and an R2 of 0.9958. However, the LSTM computation demands approximately 33 times longer training time. Energy audit results demonstrate that the photovoltaic array supplies 29.4% of the total mission energy requirement, with 8 out of 60 voyages reaching the battery protection threshold. This confirms that accurate SoC estimation is an absolute operational requirement to ensure the electrical reliability of fishing boats.

Abstract

  Solar panels in hot tropical climates lose efficiency as cell temperature rises, and active water cooling pays off only if the pump power does not exceed the energy gained. This study aimed to measure whether thermoelectric generators (TEGs) on the panel back could power that pump and to evaluate the net energy balance of self-powered cooling against a conventional system. A comparative experimental design with an off-grid prototype approach was used in Medokan Ayu, Rungkut, Surabaya, from July to October 2026. The data sources were two identical 30 Wp panels: System A (water cooling with six series SP-1848 TEG modules supplying the pump) and System B (uncooled control). Temperature, voltage, current, and power were logged automatically every minute from 09:00 to 15:00 WIB (361 records) using an Arduino Uno, DS18B20 and INA219 sensors, a DS3231 clock, and a microSD card, then analyzed by comparative descriptive analysis, line charts, and net energy calculation. System A ran warmer than System B (mean 44.5 °C vs. 36.3 °C). The TEG array produced only 0.0117 Wh against a parasitic consumption of 27.556 Wh, so System A’s net energy was −18.570 Wh versus +3.362 Wh for System B. The prototype therefore did not reach energy break-even. Future work should raise TEG yield, use a lower-power pump, redesign the water path, record battery state of charge, and repeat tests over several days.
