Abstract

Penggunaan sistem fotovoltaik (PV) yang terhubung dengan jaringan menjadi strategi yang diadopsi secara luas untuk mengurangi emisi karbon dioksida dan biaya listrik. Sejalan dengan Peraturan Pemerintah No. 79 tahun 2014, Indonesia telah menetapkan target nasional untuk menggunakan 23% energi terbarukan pada tahun 2025. Sebagaimana diuraikan dalam Kebijakan Energi Nasional (RUEN), Indonesia bertujuan untuk mencapai total 45 GW kapasitas energi terbarukan pada tahun 2025, dimana 6,5 GW (14%) diproyeksikan bersumber dari energi surya. Penelitian ini menyajikan desain sistem PV atap on-grid di Masjid Al-Hikmah, Universitas Muhammadiyah Palembang (Kampus A), yang dimaksudkan untuk mengoptimalkan penggunaan energi dan mengurangi pengeluaran listrik. Berdasarkan simulasi yang dilakukan menggunakan Homer Pro, sistem yang diusulkan terdiri dari 48 modul surya dengan total kapasitas 20 kWp, yang diintegrasikan dengan inverter on-grid Growatt tiga fase. Hasil simulasi memperkirakan produksi energi tahunan sebesar 27.306 kWh, dengan sistem PV memasok 57,7% dari total kebutuhan energi, dan 42,3% sisanya (19.985 kWh/tahun) bersumber dari jaringan listrik umum. Analisis ekonomi, dengan menggunakan tarif listrik Rp 992,72 per kWh, menunjukkan bahwa investasi ini layak secara finansial, dengan periode pengembalian modal yang diproyeksikan terjadi pada tahun ke-21 operasi.

Abstract

Corrosion is a major issue for ships operating in high-salinity seawater environments. One of the most widely applied methods of corrosion prevention is cathodic protection using sacrificial anodes. This article presents a literature review on the effectiveness of various metals used as sacrificial anodes, including zinc (Zn), aluminum (Al), and magnesium (Mg). The review highlights that each metal has unique characteristics: zinc offers stable potential and moderate service life, aluminum provides high current capacity with lightweight properties, while magnesium delivers the highest protective potential but corrodes rapidly in seawater. The selection of sacrificial anode material depends on ship operating conditions, water resistivity, and economic considerations. This review serves as a reference for the maritime industry in designing effective and cost-efficient cathodic protection systems.

Abstract

The goal of this project is to learn how to use a Crossflow turbine to create a Picohydro power plant system modeling. The manufacturing process, from design to evaluation, is the methodology employed. The turbine type utilized is a crossflow turbine, measuring 26 cm in outer diameter, 17.3 cm in inner diameter of the blade runner, and up to 35 pieces of blades. The calculations show that the distance between the blades is 2.3 cm, the blade length is 8.5 cm, the blade width is 4.4 cm, and the radius of curvature of the blade is 2.8 cm. The test results without load obtained the highest turbine rotation of 421 Rpm produces a voltage of 7.29 V before going through the boost converter.

Abstract

This research presents a vessel tracking system that provides real-time coordinate and speed information. The idea behind the development of this system originated from Automatic Identification System (AIS) technology, which functions as a vessel monitoring system in maritime areas. The system aims to improve navigation safety, monitor vessel traffic, and maritime security. In Indonesia, AIS is regulated by the Ministry of Transportation. However, this technology has not yet been implemented in river waters. In addition, AIS is a complex and expensive system. In this research, geographic location detection information in the form of a vessel tracking system is obtained using the UBlox Neo-6M GPS module based on LoRa technology. The LoRa mechanism periodically sends location data and vessel speed from the node to the gateway. The data is then sent to the ThingSpeak server using the MQTT protocol. On the server, the data can be accessed for further analysis. The developed system shows that the research can be realized and the system functions properly through a series of experimental tests. While in the in situ test, the system displayed good performance on LoRa SF 7 configuration with a signal strength of -118 dBm within the communication range of 1000 meters. This result can be improved by considering the MAPL value of -138 dBm.
