IMPLEMENTASI DATA LOGGER MENGGUNAKAN SD CARD PADA PEMBANGKIT LISTRIK TENAGA SURYA DI TAMBAK UDANG BANJARASRI KECAMATAN TANGGULANGIN KABUPATEN SIDOARJO JAWA TIMUR
Solar Power Plants (PLTS) are an environmentally friendly alternative source of renewable energy, especially in tropical regions like Indonesia. PLTS offers an ideal solution to support electrification in areas that are difficult to reach by the power grid, such as the shrimp pond in Banjarasri, Tanggulangin, Sidoarjo. This pond, covering approximately 2 hectares, utilizes PLTS to meet energy needs, particularly for nighttime lighting. However, one of the main challenges in operating PLTS is the limited real-time performance monitoring system. Failure to detect a drop in panel efficiency, damage to the solar charge controller, or battery overload can lead to energy loss and high maintenance costs. This study examines the implementation of a PLTS monitoring system using an SD Card-based data logger as an affordable and independent solution without relying on internet connectivity. The system has been tested to record parameters such as battery voltage, charging current, load current, and load voltage. Measurement results show that deviations between SD Card readings, Serial Monitor, and manual measuring instruments are very small (±0.01–0.3), demonstrating the system’s accuracy and consistency. With the support of an RTC module, data timestamping also runs synchronously and stably. In conclusion, integrating PLTS with an SD Card-based monitoring system proves effective in supporting efficient and sustainable shrimp pond operations. This technology enables early detection of system disturbances, faster technical decision-making, and long-term operational cost savings.

KOMUNIKASI DATA LORA UNTUK MENDETEKSI GANGGUAN PADA JARINGAN DISTRIBUSI LISTRIK
Disturbances in power distribution networks, such as growing trees or the presence of animals near electrical cables, can disrupt electricity flow and pose safety risks. To address this, a remote monitoring system was developed using LoRa (Long Range) communication for long-distance, low-power data transmission. The system integrates a JSN-SR04T ultrasonic sensor to measure the distance between objects (e.g., trees) and power lines. When the detected distance is less than the safe limit of 2.5 meters, a warning buzzer is triggered, and the ESP32-CAM module captures an image of the surrounding area. Data and images are transmitted via LoRa RA-02 in a point-to-point setup and displayed in real-time using an IoT platform. Testing results show that the ultrasonic sensor provides accurate measurements with an average error of 1.12%. LoRa communication remained reliable up to approximately 348 meters, with minor interference caused by physical obstacles. The ESP32-CAM successfully captured images when objects were detected. This system proves to be effective for early detection and monitoring of potential disturbances in power distribution networks

Visible Light Communication (VLC) is a wireless communication technology that utilizes visible light as a medium for transmitting information. This study develops a VLC-based audio communication system using a laser diode (LD) as a transmitter and a solar panel as an audio signal receiver. This system is designed to evaluate the performance of voice transmission in various lighting conditions (bright and dark), distances (1–48 meters), and variations in the angle of light transmission and reflection. The test results show that the system is able to transmit audio stably up to a distance of 48 meters, both in bright and dark conditions. However, the sound quality received tends to be higher and more stable in dark conditions, with an average dB value above 90 dB, and minimal interference from environmental light. In addition, high tones such as la, sol, and si show the best quality in both conditions. The test of the beam angle and reflection through the mirror also proved that the system remains effective even though the angle and distance increase, especially in low light intensity environments. From the overall results, this laser-based VLC system is proven to be an efficient, power-saving, and electromagnetic interference-resistant wireless audio communication alternative, and is very suitable for use in dark indoor environments or areas sensitive to radio waves.

PERANCANGAN ALAT PERAGA RCBO SEBAGAI PROTEKSI INSTALASI RUMAH TANGGA
Non-standard electrical installations often cause fires due to short circuits. RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is known to enhance electrical installation protection. People often neglect the dangers of non-standard electrical installations. This study designs a demonstration tool for an electrical protection system. The demonstration tool is intended to show that using non-standard electrical devices is hazardous. It effectively demonstrates the effectiveness of RCBO in protecting against abnormal conditions. The design includes testing MCB (Miniature Circuit Breaker) and RCBO as circuit breakers. The results show that RCBO is effective in minimizing electrical risks and plays a crucial role in protecting electrical equipment. In the short-circuit test, the RCBO tripped in 1.33 seconds, while the MCB tripped in 5.19 seconds. In the leakage current test, the RCBO was able to detect a leakage of 30 mA. Additionally, in the overload test at 1.8In, the RCBO tripped in 9.4 seconds, whereas the MCB tripped in 33.2 seconds. Thus, the RCBO demonstration tool created can visualize electrical hazard factors such as short circuits, leakage currents, and overloads. Moreover, the combination of RCBO and MCB is more effective as protection.
