Abstract

This study aims to design and develop an automatic fish feeding system based on the Internet of Things (IoT) that can be applied in former tin mining pits in Bangka Belitung. The system is expected to improve feeding efficiency and reduce dependence on manual labor. The research method includes hardware design using a NodeMCU ESP32 microcontroller, a servo motor as the feed dispensing actuator, and an RTC module as the time controller. The system is equipped with a web-based IoT application for remote control and monitoring. Testing was carried out at a fish farming site located in a former mining pond, with observations on feeding schedule accuracy, feed throwing distance, and feed usage efficiency. The results showed that the system achieved 100% accuracy in feed timing based on RTC sensor readings. Feed output during multiple feeder motor rotations was stable, with an error rate of less than 1%. The pellet throwing distance at 90% motor speed reached a maximum of 6.6 meters and a minimum of 2.4 meters.The system can also be controlled remotely via the web, allowing users to schedule feeding times and monitor device status in real time from a smartphone or computer. This system has proven to be effective and feasible for freshwater fish farming in post-mining areas, supporting sustainable aquaculture development.

Abstract

Tuberkulosis (TBC) merupakan salah satu penyakit yang masih menjadi masalah kesehatan utama yang ada di Indonesia, termasuk di Kabupaten Bangka. Keterlambatan diagnosis dan keterbatasan dalam akses konsultasi, turut menjadi hambatan dalam menangani kasus ini. Penelitian ini dilakukan guna mengembangkan sebuah inovasi sistem cerdas diagnosis dini TBC berbasis web yang mengintegrasikan metode Bernoulli Naive Bayes sebagai algoritma, lengkap dengan fitur Chatbot AI sebagai sarana konsultasi. Sistem ini dirancang agar masyarakat dapat melakukan pemeriksaan mandiri secara cepat dan memperoleh informasi awal melalui Chatbot AI yang interaktif. Uji coba model memperlihatkan bahwa sistem berhasil mencapai akurasi 95,24%, dengan tingkat presisi 100%, dan recall 93,33%. Selanjutnya evaluasi kinerja sistem dilakukan melalui metode Blackbox Testing untuk memastikan seluruh fitur berfungsi sesuai dengan rancangan. Dengan hasil tersebut, sistem ini dinilai mampu mendukung proses deteksi dini TBC secara lebih efektif, sekaligus menyediakan layanan konsultasi awal yang mudah diakses oleh masyarakat, khususnya masyarakat yang ada di Kabupaten Bangka.

Abstract

Technological advances in the hydroponic agricultural sector have the potential to be developed. One of them is an electrical energy efficiency system. For this reason, it is necessary to test an appropriate energy source. In this study, the test aims to determine the characteristics of the DC generator, the output of the DC generator will function as a battery charging source which is then used for energy efficiency systems in hydroponics. The test is carried out by comparing the pump height to the DC generator, the incoming water discharge and the DC generator rotation. With a pump height of a DC generator as far as 120 cm and a resistance load of 100 , the flowrate is 1L/minute, the DC generator rotation is 162 rpm and the lowest output power is 0.224 milliWatt. With the pump height to the DC generator as far as 30 cm, the flow rate is 25L/minute, the DC generator rotation is 956 rpm and the highest output power is 0.1 Watt. In other words, the greater the flow/discharge of water that enters the generator, the greater the output produced by the DC micro hydro generator.

Abstract

Indonesia is one of the countries in the world that is crossed by the equator that cause Indonesia has a duration of 12 hours (or all day). Hence, the sun can be alternative energy. For instance, it can be used for heating water. Water heaters circulating in the market are still priced in quite an expensive range, so innovation is needed. In this research, a tool is made namely a Solar Water Heater which can track the direction of the sun's rays with the addition of a reflector to reflect sunlight to get optimum heat. This study aims to see the difference between a continuous water cycle where the pump will continue to pump water into the tank through a hot cross-section with a delayed water cycle where the pump will stop for 10 seconds so that the water sits on the copper pipe first. Based on the test results, it was found that the Solar Water Heater can heat water in the tank up to 47.35 degrees Celsius in unstable weather and the optimum method for heating the water is the continuous method which has a difference of 6,47 degrees Celsius with the delay method.

Abstract

Thermoelectric Generator (TEG) is a technology that can convert heat energy into electrical energy directly due to the difference in temperature between the hot side and cold side of the thermoelectric module, known as the Seebeck effect. This study uses a thermoelectric module of the SP 1848 type. An aluminum plate is used as a medium for absorbing heat from a simulated iron temperature with a maximum temperature of 75°C, while the cold side of the thermoelectric module uses a heatsink with a temperature of 33°C and a fan. From the tests carried out, the maximum voltage produced when two TEG modules are connected in series is 1.65 Volt with a temperature difference of 43.13°C. The maximum current generated when two TEG modules are connected in parallel is 3.52 Ampere with a temperature difference of 42°C.
