Kualitas air pada tanaman hidroponik merupakan hal yang sangat berpenganuh pada pertumbuhan tanaman. PH dan TDS merupakan parameter yang mempengaruhi kualitas air. PH yang terlalu asam ataupun basa akan menghambat penyerapan nutrisi oleh akar tanaman. Nilai TDS yang rendah menujukkan kurangnya nutrisi dan berdampak pada pertumbuhan tanaman yang tidak optimal ataupun …
Penelitian ini bertujuan untuk merancang sistem komunikasi antara Variable Speed Drive (VSD) dan Soft PLC untuk mengontrol kecepatan motor induksi tiga fasa. Pendekatan ini menggantikan PLC konvensional dengan Soft PLC, yang lebih hemat biaya dan fleksibel. Sistem dikembangkan menggunakan software Codesys, Arduino Uno, protokol Modbus TCP, dan sensor Infra Red (IR) untuk pengukuran ke…
A power transformer is an important piece of equipment in the distribution of electrical energy which is expected to operate continuously and have a service life that is in accordance with its estimates. Transformer loading is one of the factors that influences the remaining useful life of a power transformer. This research aims to predict loading using the ARIMA method and calculations to dete…
Mountain climbing often involves unpredictable risks that can result in climbers getting lost, especially due to limited access to internet signals in mountainous areas, which makes it difficult for climbers to determine their location. This research aims to monitor climbers' locations using Global Positioning System (GPS) and Long-Range (LoRa) technology. The device operates by sending…
This study aims to design a State of Charge (SOC) estimator for Lithium-ion batteries using the Recursive Least Squares (RLS) method. SOC is an important parameter in Battery Management Systems (BMS) that serves to monitor the remaining capacity and act as an indicator of battery health. The RLS method is applied to estimate the regression parameter coefficients in SOC estimation by iteratively…
Based on BMKG data in 2022-2023 in the Semarang Regency area has a lightning strike density of 10-30 strikes / year. The Gedong Songo Temple area includes historical places and places of worship for Hindus and has the potential threat of lightning strikes. The planning of the lightning distribution protection system in the Gedong Songo temple area refers to the SNI 03-7015-2004 standard and the…
Increasing energy consumption is driving the development of renewable energy sources, including solar panels. However, the efficiency of solar panels often decreases due to the partial shadow effect, which reduces the output power. This research aims to develop an Arduino-based adaptive reflector and LDR sensor to improve the efficiency of solar panels. The research method involves desi…
Penelitian ini bertujuan untuk memprediksi baterai NiCd 110 VDC Unit 1 di Gardu Induk Jajar yang berusia lebih dari 10 tahun, berdasarkan hasil pengujian operasi discharging pada tahun 2019, 2022, dan 2024. Baterai yang telah beroperasi sejak Mei 2010 menunjukkan penurunan performa, ditandai dengan penurunan kapasitas dari 211 Ah (2019) menjadi 170 Ah (2024), serta efisiensi dari 100% (2019) m…
