Abstract

Abstract—Public street lighting (LPJU) is a road infrastructure that is very important for road users at night. The constraints faced by User managers in an area in LPJU management are the problem of maintenance, monitoring, electricity consumption, and limited workforce. In an effort to overcome this problem, this study designed a tool in the LPJU system that can control LPJU ignition according to user needs by combining the timer and light sensor functions, and can monitor electricity consumption by calculating the power consumption or kWh meter and recording data on accumulation of electric power consumption every day at 06.00 WITA automatically stored on the micro SD Card. The accumulated data last recorded for 1 (one) month at the beginning of each month at 08.00 WITA will be sent using SMS services to users periodically. In addition, the user can monitor at any time with the "lapor" SMS format, the monitoring data sent in the form of the last electrical power consumption used by LPJU at that time.

Abstract

Kutampi Diesel Power Plant that supplies the Lembongan Island electrical system has a reliability value index that has not met the standard with SAIDI 95.85 hours / customer / year and SAIFI 76 times / customer / year while the WCS standard for SAIDI is 2.5 hours / customer / year and SAIFI is 3 times / customers / year. Reliability value can be improved one of them by adding recloser. The addition of the recloser should pay attention to the area of frequent interference, the percentage of load and impedance of the electricity system. The VEGA method was used to determine the optimal recloser location by minimizing the SAIDI and SAIFI values. The result of the optimization method using VEGA shows optimal recloser location in the group 5 with the highest fitness 8,8396 with SAIDI 0,0070 hour / customer / year and SAIFI 0,0061 times / customer / year with program running time ± 3,6 minutes. These values indicate the VEGA method is more accurate than the fuzzy and genetic algorithm combination method but requires a longer running time.

Abstract

Electricity monitoring is making to determine the quality of electricity used. Currently, electricity monitoring is still done manually together with it requires a system that can measure the electrical parameters automatically. Therefore, an electrical monitoring system is designed for a three-phase system based on a wireless sensor network (WSN) using LoRa communication. The system consists of a transmitter node as a measured voltage, current, frequency, power factor, and active power using the PZEM-004T module. The receiver node is a gateway that receives data from the transmitter node used LoRa transmission and then forwards the data to be stored in a database using the internet network. The receiver node is equipped with backup data when the node receiver cannot be connected to the internet network. Finally, web monitoring is designed to make it easier for users to access electricity monitoring data online. Web monitoring will display data onto voltage, current, frequency, power factor in a single-phase system and active power in the form of the three-phase system into tables and graphs.

Abstract

Keberadaan gardu induk dalam sistem tenaga listrik mutlak diperlukan. Gardu induk sendiri merupakan suatu instalasi yang terdiri dari peralatan listrik yang berfungsi untuk mengubah daya listrik tegangan tinggi menjadi tegangan tinggi atau tegangan menengah lainnya. Untuk mendukung kelancaran penyediaan tenaga listrik dan menjamin kontinuitas kelistrikan, kemampuan peralatan yang ada di gardu induk sangat perlu mendapat perhatian khusus, seperti pengawasan dan perawatan secara berkala. Misalnya saja di Gardu Induk Nusa Dua yang lokasinya dekat dengan pantai dan hutan mangrove, banyak terdapat burung-burung liar yang berkeliaran dan mencari makan atau bahkan membuat sarang di area Gardu Induk Nusa Dua. Keberadaan burung-burung liar tersebut tentu dapat mengganggu operasional gardu induk, seperti membuang kotoran dan membuat sarang di peralatan listrik gardu induk. Burung-burung liar tersebut akan hinggap di peralatan yang ada di gardu induk dan tidak jarang juga akan membuang kotoran di peralatan yang dihinggapinya. Kotoran yang tidak dibersihkan lama-kelamaan akan mengeras dan dapat menimbulkan gangguan berupa titik api dan korsleting pada peralatan. Gangguan hotspot dan arus pendek pada gardu induk merupakan kendala yang tidak diinginkan oleh penyedia listrik dalam mengoperasikan sistem kelistrikannya. Maka dari itu kelompok kami berencana untuk membuat sebuah prototipe yang dapat memancarkan gelombang suara dengan frekuensi yang tidak disukai burung dengan memanfaatkan IoT dan sinar matahari sebagai sumber tenaganya. Dengan begitu, alat ini dapat dioperasikan melalui internet dan memiliki sumber energi sendiri, sehingga dapat dioperasikan dengan mudah dan dapat ditempatkan di tempat yang sulit dijangkau tanpa memerlukan perawatan yang berarti.

Abstract

Biomass is one of the materials that can be utilized as fuel. To ensure optimal quality, effective management of biomass is required to maximize its potential. One possible approach is the application of a biomass stove fueled by rubber wood pellets. By integrating a thermoelectric generator, data can be obtained to determine whether all aspects meet the established standards. This system is designed to generate electrical energy from combustion heat, supported by components such as a buck-boost converter and a 3V DC lamp. Testing was carried out using proximate and ultimate analyses on the fuel as well as the Water Boiling Test (WBT) on the stove, referring to SNI 8021:2020 and SNI 8021:2014 standards. The results showed that rubber wood pellets contained 7.64% moisture and had a calorific value of 4050 kcal/kg. The stove demonstrated an efficiency of 23.53%–37.28% and a fuel consumption rate of 0.61–0.77 kg/hour, both of which meet the requirements. In addition, the thermoelectric generator produced a voltage of 3.6 V and an electric current of 0.05 A, which are higher than those reported in previous studies (2.06 V and 0.01 A, respectively). Therefore, this thermoelectric biomass stove system is considered successful and feasible for further development as an alternative energy application.
