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…

Fulfillment of plant nutrition is one of the important things in cultivating a hydroponic system. Part Per Million (ppm) is a unit for measuring the concentration of a liquid solution. Non-ideal ppm values can affect the growth rate of hydroponic plants to be suboptimal. In general, the process of providing nutrients can be done manually by farmers, however, for larger and more complex agricult…
This study developed a broiler cage temperature prediction model using the Long Short-Term Memory (LSTM) algorithm to help farmers maintain cage temperature in the optimal range (20°C-32°C). The problem of unstable cage temperature can cause thermal stress, reduce productivity, and even increase the risk of broiler death. The temperature monitoring system is designed using a DHT11 sensor …
The close house chicken coop is a type of cage that is widely used in the industrial era 4.0 because it has good environmental conditions. This cage can be used by broiler chickens. The environment where broiler chickens are grown has a significant effect on chicken meat productivity so it needs to be maintained properly. These environmental components include the …
The brooding phase, which starts from one-day-old chicks (DOC) until 14 days of age or until the chickens can be transferred from the artificial incubator or heater, is a critical stage in the poultry industry, particularly for chickens. To ensure optimal environmental conditions during this phase, a reliable and continuous monitoring and data acquisition system is required. This study develops…
