Abstract

Penelitian ini melakukan analisa SPP pada gedung bertingkat dan pengaruh induksi petir terhadap perangkat elektronika yang berada didalam gedung. Pengujian simulasi jaringan listrik, rangkaian elektronika, dan sistem proteksi terhadap petir dari Program Alternative Transient (ATP) dieksekusi dengan menggunakan program EMTP (Electromagnetic Transient Program). Hasil pengujian menunjukkan arus induksi petir cenderung mengalir pada resistansi pentanahan jaringan listrik yang semakin kecil sehingga arus induksi yang mengalir ke jaringan listrik dan perangkat elektronik berkurang yang mengakibatkan tegangan lebih transien yang terjadi pada perangkat elektronik menurun. Saat terjadi induksi petir dengan arus puncak impuls petir Io=100 kA dan bentuk gelombang 10/350 s untuk kondisi tanah lembab (g=100 cm) dan basah (g=30 cm), perangkat sound system yang berada di lantai dasar dan personal computer yang berada di lantai 1 dengan resistansi pentanahan jaringan listrik 210  menghasilkan tegangan lebih transien sebesar 714,49 V1105,60 V yang dapat merusakkan perangkat karena melampaui batas maksimum standar eropa.Kata kunci : Sambaran petir tidak langsung, peralatan tegangan rendah dan elektronik, ground potential rise, sambaran induksi petir,ATP/EMTP.

Abstract

Limited water availability during the dry season and reliance on diesel-powered pumps remain major obstacles to rice field irrigation in Ulak Depati Village, as diesel pumps require high operating costs and inefficient manual operation. This community engagement activity aims to design and implement an Arduino-based, solar-powered automatic water pump system that operates according to soil moisture conditions, as well as to improve the partner farmer group's knowledge and skills in operating and maintaining the system. The system consists of solar panels, a solar charge controller (SCC), a battery, an Arduino Uno, a soil moisture sensor, a relay module, a solid-state relay (SSR), and a DC water pump. The implementation stages included socialization, field surveys, system design and assembly, field installation and testing, and training and mentoring for the farmer group. The results showed that the Arduino Uno successfully processed sensor data to control the pump automatically, turning the pump on when the sensor value exceeded 450 and stopping it at values of 450 or below. Field testing delivered 2,513.60 liters of water with a water level of 4.7 cm over 246 minutes, while the training evaluation involving 15 participants achieved an average satisfaction rate of 93%. These findings indicate that the program effectively supports automatic solar-powered rice field irrigation and enhances the farmers' capacity to manage appropriate technology independently

Abstract

Agricultural irrigation in Ulak Depati Village remains constrained by dependence on diesel-powered pumps, limited water availability during the dry season, and unstable electricity supply. This study aimed to design an Arduino-based automatic irrigation pump powered by a Solar Power Generation System (PLTS), determine the energy requirements and capacity of solar panels and batteries, and evaluate system performance in supporting agricultural water resilience. The study employed literature review, observation, discussion, and consultation methods. The designed system consisted of three 200 Wp solar panels connected in parallel, a 40 A MPPT Solar Charge Controller, two 12 V 100 Ah batteries connected in series, an Arduino Uno, a soil moisture sensor, and a DC water pump. The results showed that the total daily energy requirement was 706.5 Wh, with the water pump being the largest energy consumer at 671.38 Wh/day. The minimum required solar panel capacity was 141.3 Wp based on an effective peak sun hour of 5 hours/day, while the installed capacity was 600 Wp. The minimum battery capacity was 60 Ah at 24 V, whereas the system used a 100 Ah battery with stored energy of 2,400 Wh. Testing showed that the pump operated at 23.23–24.30 V and 6.43–7.20 A, while water volume reached 2,513.60 L after 246 minutes of operation. The PLTS was theoretically capable of producing 3,000 Wh/day, exceeding the daily energy requirement. These results indicate that the proposed system can meet the energy needs of the automatic irrigation pump and provide energy reserves to support irrigation continuity under reduced solar irradiation conditions.
