Abstract

Abstrak Pengembangan listrik tenaga surya yang berbasis kepada efek photovoltaic dari peranti sel surya sebagai salah satu sumber tenaga listrik alternatif merupakan salah satu pilihan yang tepat saat sekarang ini dimana banyak perusahaan pembangkit energi terbarukan yang berlomba lomba untuk mengembangkan penggunaan photovoltaic. Akan tetapi dalam pengaplikasiannya, kemampuan dari panel surya untuk menghasilkan tenaga listrik, belum optimal. Karena pengaturan sudut penerimaan cahaya pada panel surya yang masih belum efektif. Sehingga diperlukan sebuah pengontrol gerakan dari penampang tempat panel surya berada, agar dapat diperoleh suatu sudut kemiringan yang sesuai dengan arah dating cahaya matahari sehingga kemampuan panel surya dalam menghasilkan energi listrik bias lebih optimal. Panel surya akan bekerja dengan baik, apabila memiliki posisi yang tegak lurus dengan arah datangnya sinar matahari. Dengan demikian, sistem yang akan dirancang bertujuan agar posisi panel surya, tetap tegak lurus dengan arah datangnya sinar matahari. Pada sistem ini digunakan module Real-Time Clock yang akan mengirimkan data waktu ke NodeMCU sebagai microcontroller untuk diolah menjadi data sudut dengan metode perhitungan azimuth. Setelah didapatkan sudut posisi matahari maka Microcontroller akan menggerakkan motor servo pada penampang tempat panel surya berada sehingga posisi panel surya tegak lurus dengan posisi matahri.Dari perancangan sistem ini, dihasilkan sistem yang secara otomatis mampu untuk mengontrol posisi dari panel surya agar tetap tegak lurus dengan cahaya matahari. Kata kunci : panel surya, optimal, Real-Time Clock, azimuth, motor penggerak, tegak lurus Abstract The development of solar electricity based on the photovoltaic effect of solar cell devices as an alternative power source is one of the right choices right now, where many renewable energy companies try to make develop photovoltaic. However, on the application, the ability of solar panels to produce electricity is not optimal yet. Because of the arrangement of the angle of reception of light on solar panels that are still not effective. So we need a motion controller from the cross section where the solar panel is located, so that a slope angle can be obtained that corresponds to the direction of the sun's light, so that the ability of the solar panel to produce electrical energy can be optimized. The solar panel will work well, if it has a position that is perpendicular to the direction the sun is coming from. Therefore, the system that will be designed aims to position the solar panel, remaining perpendicular to the direction of sunlight. In this system, Real-Time Clock module is used to send time data to NodeMCU as a microcontroller to be processed into angular data with azimuth calculation’s method. After obtaining the angle of position of the sun, the microcontroller will move the servo motor in the cross section where the solar panel is located so that the position of the solar panel is perpendicular to the position of the sun.

Abstract

Photovoltaic (PV) systems are a promising renewable energy source due to their ease of installation, eco-friendliness, and abundant solar radiation availability. Indonesia has a theoretical potential of 4.625 kWh/m² and a practical potential of 3.767 kWh/kWp; however, as of September 2021, its installed capacity was only 194 MW. Land constraints have led to the development of floating PV systems, which reduce land usage and enhance module efficiency due to lower temperatures above water. Nonetheless, PV systems face challenges from solar radiation intermittency, influenced by cloud opacity, causing output power fluctuations. This study maps cloud opacity patterns on Kodingareng Island based on dry and rainy seasons using 2020 BMKG data. Results indicate that output power during the dry season is more stable than in the rainy season due to lower cloud cover. Conversely, thick cloud cover during the rainy season reduces solar radiation reaching PV modules, resulting in fluctuating power output. Thus, floating PV systems demonstrate better energy availability during the dry season. This study highlights the importance of understanding cloud opacity patterns in planning floating PV systems to address the challenges of solar radiation intermittency.

Abstract

Indonesia, as an archipelagic country with over 17,000 islands, faces significant challenges in providing electricity access, particularly to small and remote islands. One promising solution is Solar Power Plants (PLTS), both land-based and floating solar plants that utilize water surfaces, suitable for areas with limited land availability. This study evaluates the economic feasibility of floating solar plants and land-based solar plants using the Levelized Cost of Electricity (LCoE) approach. LCoE encompasses all costs of construction, operation, maintenance, and energy production over the plant's lifespan, serving as a key benchmark in selecting power generation technologies. The findings show that the LCoE for floating solar plants is Rp11,197.00/kWh, lower than land-based solar plants at Rp11,769.00/kWh, although both exceed the electricity purchase price in Kodingareng, South Sulawesi, at Rp2,460.00/kWh. This difference is influenced by higher construction costs for floating solar plants but offset by greater energy output and lower operation and maintenance costs. This research provides a basis for developing solar power systems in archipelagic regions, emphasizing efficiency and sustainable energy solutions.

Abstract

Pemanfaatan teknologi dalam pendidikan dasar menjadi semakin krusial di tengah perkembangan era digital dan Revolusi Industri 4.0. Kegiatan pengabdian ini dilatarbelakangi oleh pentingnya peningkatan literasi teknologi di lingkungan sekolah dasar, khususnya dalam pemanfaatan kecerdasan buatan (Artificial Intelligence/AI) untuk mendukung proses belajar mengajar yang lebih interaktif dan adaptif. Program ini dilaksanakan di UPT SD Negeri 16 Parepare dengan tujuan utama untuk mengimplementasikan pendekatan pembelajaran berbasis AI. Metode pelaksanaan meliputi pelatihan intensif kepada guru mengenai konsep dan praktik penggunaan AI, penerapan langsung AI dalam kegiatan pembelajaran di kelas, serta evaluasi untuk mengukur dampak kegiatan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman dan keterampilan guru dalam mengintegrasikan AI ke dalam pembelajaran, serta meningkatnya minat dan partisipasi aktif siswa selama proses belajar. Kegiatan ini memberikan kontribusi positif dalam memperkenalkan transformasi digital di lingkungan sekolah dasar, serta berpotensi menjadi model replikasi untuk sekolah lainnya.
