Abstract

This research addresses the problem of temperature fluctuations affecting the efficiency of solar panels. A cooling system has been developed using a Peltier and a combination of air- and water-cooling methods. The air-cooling system involves placing a Peltier coated with a heatsink under the solar panel, while the water-cooling system uses pumped water on the panel's surface. The study aims to design a solar panel cooling system to reduce temperature and power losses and compare its output to standard solar panels. The system includes a Peltier, DC fan, and heatsink. Results indicate that the air-cooling system reduced temperature losses on the bottom milk of solar panels by 14.5%. However, the surface of solar panels showed no reduction in temperature losses. Additionally, solar panels with cooling systems were able to reduce power losses by 4% compared to standard solar panels. This research suggests that the use of an air-cooling system utilizing Peltier as the cooling medium could be a potential solution to reduce temperature losses and power losses on solar panels.

Abstract

Current technological developments generally use sophisticated equipment which is categorized as a non-linear load. The massive use of non-linear loads causes side effects on the quality of electric power. Electric power systems that are connected to non-linear loads will experience distortion in current and voltage by harmonics due to the engineering of voltage waveforms due to the installation of many converters operating at frequencies that do not match the utility frequency of 50 or 60 Hz. Taking into account the great benefits for humans, the use of non-linear loads cannot be reduced but can be applied by keeping non-linear loads operating with good quality electric power. Therefore, harmonic filter equipment is needed to reduce harmonics. Passive filters and active filters can be used where active filters have many advantages compared to passive filters because they can adjust to varying working frequencies. To obtain more optimal harmonic reduction results, an active filter Shunt Active Power Filter (SAPF) using a PI controller tuned with the Gray Wolf Optimizer (GWO) optimization method is designed. The SAPF PI-PSO method is used as a comparison. The SAPF experiment on the IEEE 14 bus test system, PSO obtained better ITAE error results and computation time than GWO. The ITAE value and PSO computing time were 108.5821 second and 4255.097192 second, respectively, while GWO obtained 109.0172 second and 4379.461 second. However, the GWO-tuned SAPF is more able to reduce the THD of the 12 bus current on the IEEE 14 bus system by 13%.

Abstract

Sistem Informasi dan Manajemen Laboratorium (SIMLAB) merupakan solusi digitalisasi untuk mengelola kegiatan laboratorium di Institut Teknologi Kalimantan. Penelitian ini mengimplementasikan metode Scrumban sebagai pendekatan hybrid antara Scrum dan Kanban dalam perancangan ulang SIMLAB menggunakan teknologi Laravel dan React. Sistem dikembangkan dengan menerapkan design pattern Repository, Service, Observer, dan Factory untuk mengoptimalkan arsitektur aplikasi. Fitur utama yang dikembangkan meliputi modul admin, peminjaman alat laboratorium, dan pengajuan praktikum. Metodologi Scrumban dipilih untuk memberikan fleksibilitas dalam mengelola backlog sekaligus mempertahankan struktur sprint yang terorganisir. Hasil pengujian menunjukkan bahwa sistem berhasil meningkatkan efisiensi pengelolaan laboratorium dengan response time rata-rata 1.2 detik dan tingkat kepuasan pengguna mencapai 87.5%. Implementasi design pattern Repository menghasilkan kode yang lebih maintainable dengan cyclomatic complexity rata-rata 3.2.
