Abstract

Grounding system performance is strongly influenced by soil moisture and temperature, which can vary significantly due to environmental conditions. The lack of real-time monitoring may cause grounding resistance to exceed safety limits, particularly during dry seasons. This study aims to design and evaluate a microcontroller-based grounding resistance control system capable of maintaining resistance below 5 Ω through real-time monitoring and automatic soil conditioning. An experimental method was applied at an active grounding installation in the Multi Integra Building, Rawamangun, Jakarta, representing tropical soil conditions with variable moisture content. The proposed system integrates soil moisture and temperature sensors, a microcontroller, and a water pump actuator operating in a closed-loop control scheme. Grounding resistance measurements were conducted before and after automated irrigation and validated using an earth resistance tester. The results show a clear inverse relationship between soil moisture and grounding resistance. Initial dry soil conditions produced an average grounding resistance of 6.095 Ω. After controlled irrigation, soil moisture increased to approximately 63.5% and soil temperature decreased, resulting in a significant reduction of grounding resistance to an average of 0.707 Ω. These findings confirm that active soil moisture control effectively stabilizes grounding performance and enhances electrical safety

Abstract

Pemantauan pH di UPTD Budidaya Benih Ikan Bojongsari masih dilakukan secara manual dan berkala. Hasil observasi awal menunjukkan belum tersedia sensor permanen, dashboard jarak jauh, pencatatan otomatis, maupun sumber energi PLTS. Kegiatan Pengabdian kepada Masyarakat ini bertujuan mengimplementasikan sistem monitoring pH berbasis Internet of Things (IoT) yang didukung Pembangkit Listrik Tenaga Surya (PLTS). Metode kegiatan meliputi survei kebutuhan, perancangan, perakitan, pemrograman ESP32, instalasi, pengujian fungsional, pelatihan, dan evaluasi mitra. Sistem mengintegrasikan sensor pH, suhu, dan TDS dengan LCD dan dashboard web. Hasil uji menunjukkan seluruh fungsi utama yang diuji dapat bekerja; tegangan panel surya terukur 17,32 V, tegangan baterai 12,01 V, dan keluaran sistem 12,14 V. Dashboard menampilkan suhu 24,3 °C, pH 9,3, dan TDS 65 ppm; nilai pH tersebut kemudian diklasifikasikan sebagai kondisi basa/tidak normal. Evaluasi delapan butir oleh satu perwakilan mitra menghasilkan skor rata-rata 4,25 dari skala 5, dengan 75% butir berkategori puas dan 25% sangat puas. Karena kegiatan belum menggunakan pre-test-post-test, kalibrasi pembanding jangka panjang, dan evaluasi biologis, hasil ini ditafsirkan sebagai keberhasilan implementasi fungsional dan penerimaan awal mitra, bukan bukti peningkatan kompetensi atau kelangsungan hidup benih ikan.

Abstract

Three-phase induction motors have the drawback of high starting currents, reaching 5 to 7 times the rated current, which can potentially interfere with other equipment on the same circuit. This study aims to design a trainer kit, analyse phase sequences, and compare the starting currents of three-phase induction motors using the DOL and Star-Delta starting methods in forward mode. The experimental method was implemented by assembling a trainer kit with components such as an MCB, contactor, TOR, and TDR. Testing involved measuring the phase sequence using a Phase Rotation Tester and the starting current using an ampere clamp with varying DC injection braking loads of 0–200 VDC. The results show that the trainer kit functions optimally, with the phase sequence of the power source and the motor in forward mode (R-S-T) rotating clockwise (CW). In the analysis of starting current, the Star-Delta starting method was shown to significantly reduce current surges compared to the DOL starting method. Under no-load conditions at 0 VDC, the Star-Delta method reduced the starting current by 65.98%, from 0.97 A to 0.33 A. However, at a maximum load of 200 VDC, the reduction effectiveness decreased to 31.10%, from 2.99 A to 2.06 A. Star-Delta starting is highly effective at reducing starting current, although its effectiveness decreases as the motor’s mechanical load increases.
