Karena meningkatnya kebutuhan listrik masyarakat Indonesia setiap tahunnya, penelitian sedang dilakukan untuk mengubah energi matahari menjadi energi listrik yang ramah lingkungan melalui konversi panel surya yang menghasilkan arus searah (DC). Karena sebagian besar panel surya diletakkan dalam posisi statis atau tidak bergerak, kemampuannya dalam menyerap sinar matahari tidak maksimal. Dengan menggunakan solar tracking sumbu ganda, posisi panel surya harus selalu melacak pergerakan cahaya matahari guna memaksimalkan energi matahari. Untuk mengetahui cara terbaik dalam menyerap sinar matahari, penelitian ini akan membandingkan daya listrik yang dihasilkan panel surya dengan dan tanpa solar tracking (statis). Penelitian ini menggunakan metodologi komparatif untuk mengetahui perbedaan keluaran daya antara solar tracking dan panel surya statis. Tegangan (V) diukur dengan multimeter, dan arus (I) diukur dengan tang ampere. Empat sensor LDR digunakan pada pelacak surya ini untuk mendeteksi sinar matahari. Mikrokontroler Arduino membaca keluaran sensor LDR dan menyalurkannya ke motor servo yang menggerakkan panel surya. Pengujian menggunakan panel surya statis dan solar pelacak, serta pengumpulan data arus (Ampere) dan tegangan (Volt) selama delapan jam, mulai pukul 08.00 WIB hingga pukul 16.00 WIB. Berdasarkan hasil pengukuran tegangan dan arus diperoleh daya total (P) sebesar 6,30 W tanpa solar tracking (statis) dan 30,37 W dengan menggunakan solar tracking. Hasil perhitungan panel surya dengan solar tracking dan tanpa solar tracking memperoleh persentase arus sebesar 78,37% dan daya sebesar 79,26%. Hasil penelitian ini mengungkapkan bahwa panel surya dengan menggunakan solar tracking lebih efisien dan optimal dalam menyerap sinar matahari dibandingkan tanpa solar tracking (statis).

The Unmanned ships have become a primary focus in maritime technology development to enhance efficiency and navigational safety in waters. In this research, a unmanned ship utilizing ESP32CAM as its core system is designed to detect navigation lights of other vessels and avoid potential collisions. The initial response of the ESP32CAM camera reads the colors of lights approaching the unmanned ship within a distance of less than 100cm. The ESP32CAM reads and identifies colors through image processing. When the ESP32CAM detects green and red lights, it commands the buzzer to sound. The color detection system works such that when the ESP32CAM detects a red light, it sends a signal to the servo motor to move left, and when it detects a green light, it sends a signal to the servo motor to move right. The servo motor functions as the ship's rudder. Testing of the navigation light system with ESP32CAM camera to prevent ship collisions is conducted with predetermined scenarios, including testing with red LEDs, green LEDs, and overall system testing. The results show that the navigation light system with ESP32CAM camera functions well. The ESP32CAM camera can optimally identify light colors at a distance of 100cm. Based on the conducted research, the ESP32CAM camera is capable of reading both the distance and colors of lights as specified at a distance of 100cm.

In the era of maritime technology, Unmanned Surface Vehicles (USVs) are becoming the main vehicles on the water surface, controlled from land and capable of transmitting live data. USVs have a wide range of survey and exploration applications, relying on hydrographic knowledge for accurate mapping. USV development has adopted a double hull design, improving stability and wave resistance. Survey data transmission requires advanced technology, with Long Range (LoRa) technology being the solution for long distance data transmission with low power consumption. LoRa utilisation is expected to increase the efficiency of USVs in hydrographic surveys. The research and development (R&D) research method is used as the main approach in this research with the aim of creating and developing USVs that can increase efficiency in hydrographic surveys. The USV is equipped with an RPM sensor and flowmeter used to monitor the movement control of the USV in the waters. In addition, a depth detector is used to monitor the topography of the seabed. In order for this USV to run using a remote control that is controlled from land. The USV drive consists of a BLDC motor connected to the propeller and a servo motor connected to the ship's rudder. Furthermore, the data taken from the sensor is sent via LoRa to be delivered to the ground station. From the USV test results, it was found that the data transmission range with LoRa Ra-02 under Line of sight (LOS) conditions was 340 metres while under Non Light of sight (NLOS) conditions it was around 200 metres. The average speed travelled by USV is 0.616 km/hour in operational survey conditions and can be faster in non-operational survey conditions. The error value of the RPM sensor is obtained at 1.604% with a reading accuracy of 98.936%.

Irrigation is a land irrigation system by damming water sources. Irrigation as the provision, regulation and disposal of water to support agricultural needs. Irrigation is generally used by farmers, especially farmers in rice fields to irrigate and provide water supply to agricultural land, monitoring water stock in rice fields must be done frequently because rice water needs must be balanced with a lack of water supply or excess water supply in rice fields is not good for rice growth . So far, farmers have monitored irrigation channels manually, the location of the rice fields from the farmer's house often causes rice plants to experience scarcity because the floodgates are not opened when the water supply is running low or experiencing water supply. excess because the floodgates are opened for too long, this will greatly disturb the growth of rice plants.
