Abstract

Penelitian ini bertujuan untuk meningkatkan kinerja Dermaga Island Berth dengan mengimplementasikan energi terbarukan dan sistem perlindungan yang efektif. Upaya dilakukan untuk meminimalkan potensi-potensi yang dapat menghambat atau menghentikan operasional dermaga. Langkah-langkah yang diambil meliputi pemasangan perlindungan katoda pada pipa dan struktur dermaga, serta perancangan kebutuhan energi cadangan. Berdasarkan hasil perhitungan, dermaga Island Berth membutuhkan 24 modul panel surya dengan spesifikasi 410wp.

Abstract

Solar panels have relatively low efficiency, but their performance can be enhanced by a tracking system directing the panels perpendicular to the light source and adding reflectors to capture more sunlight. The dual-axis solar tracking method, using two linear actuators and optimized by fuzzy logic, efficiently positions solar panels for maximum sunlight exposure. This research aimed to improve the overall efficiency of solar panels by integrating reflectors with a dual-axis solar tracking system optimized by fuzzy logic. Specifically, this research tested various reflectors to determine the most significant efficiency improvement. This research consisted of two tests: a tracking test and a reflector test using a halogen lamp. The tracking test was conducted by positioning the light in four different positions. The light sensor data were obtained before and after the solar tracking, indicating that the tracking was successful. All these tests were conducted with the light source radiation of 1,168 W/m2. This research concluded that the tracking system effectively positioned the solar panels toward the light source, with the tracking time ranging from 12 to 16 s, depending on the position. Aluminum foil is the most cost-effective reflector, priced at IDR5,341 per 1% increase in efficiency, compared to mirrors at IDR20,204 per 1% and reflective tape at IDR48,034 per 1%. In conclusion, the integration of aluminum foil reflectors and a dual-axis solar tracking system, optimized by fuzzy logic, significantly improves the efficiency of solar panels, which is both cost-effective and efficient.

Abstract

The problem of limited access to electricity in the agricultural sector will have a direct impact on the suboptimal operation of smart greenhouses, including irrigation systems, additional lighting, and sensor-based environmental monitoring. The absence of a reliable energy source makes it difficult for farmers to maintain the stability of the planting environment, especially in remote areas that are not covered by the PLN electricity network. This community service activity aims to design an off-grid Solar Power Plant (PLTS) system as an independent energy solution that is efficient, environmentally friendly, and accessible to farmers in the location. The methods used include direct surveys to obtain data on electricity load requirements, measuring location conditions to determine orientation and potential for solar radiation, and technical calculations of the system based on field data. The result of this activity is a PLTS system design with a 2320 Wp solar panel configuration, 3 kW inverter, and 48V 150Ah battery, which is projected to be able to meet the daily energy needs of 2880 Wh and can maintain greenhouse operations for two days without sunlight. This activity also provides benefits in increasing farmer literacy regarding solar energy technology and encouraging initiatives to implement similar off-grid PLTS systems independently. This community service activity shows that the design of an off-grid PLTS system based on actual needs has great potential to be replicated as a sustainable energy solution in the agricultural sector.

Abstract

In today's electrical infrastructure, a significant portion continues to depend on the AC (alternating current) system, necessitating energy conversion from DC (direct current) to AC during power generation and vice versa when reaching consumers. Nonetheless, as renewable energy sources and DC-based electronic devices gain popularity, the DC electrical system presents an attractive alternative. This research compares the energy efficiency between AC and DC electrical systems in school buildings. Through literature review and energy analysis in school buildings, the study found that the DC electrical system is significantly more efficient, achieving an efficiency rate of 89%. In contrast, the AC system only reaches 84%. The implications of this research provide valuable insights for implementing more efficient and sustainable electrical systems in buildings in the future.

Abstract

Indonesia's heavy reliance on non-renewable energy sources, such as fossil fuels and other resources obtained from mining, poses sustainability challenges. Solar panels, which are environmentally friendly and renewable energy alternatives, are designed to convert solar energy into electricity, and they have shown room for improvement in their efficiency. One method to enhance its efficiency is the utilization of dual-axis solar tracking, employing linear actuators for control over both horizontal and vertical panel movements. In addition, solar panels frequently experience efficiency losses as a result of high working temperatures when exposed to sunlight. The use of water treatment techniques may help address this problem. In this research, the two-axis solar tracking approach with water treatment methods were combined to achieve greater efficiency and boost energy production. A notable increase in solar panel efficiency was seen subsequent to the design, implementation, and testing of the proposed system, resulting in a notable rise in power output. Combining the two-axis solar tracking approach with water treatment methods produced solar panels with a 7.46% efficiency and a 17.77% power increment. Dual-axis solar tracking and combined with water treatment could significantly increase solar panel efficiency, which will ultimately lead to environtmentally clean renewable energy production increment.

Abstract

The implementation of a small-scale Micro-Hydro Power Plant which considering a 2-meter water head river will be discussed in this research. Therefore, a Micro-Hydro Power Plant with a Propeller turbine type was implemented. The turbine components include the turbine wheel, blades, guide vanes, turbine housing, turbine cover, and discharge pipe. Each component was manufactured using a 3D printing process with PLA filament. The testing process involved a miniature dam made from a container with a height of 1 meter, connected vertically with pipes. Water flowing into the turbine rotates the turbine wheel, causing it to rotate on the turbine shaft. Output data, including rthe number of rotations (RPM) and torque (M), were collected using sensors placed on the turbine wheel shaft. The testing results of the prototype Propeller turbine showed an efficiency of over 90% at a flow rate of approximately 0.008 m^3/s. Under the ideal design conditions with 90% efficiency, the prototype turbine would operate at a rotation speed of 2880 RPM and generate a power output (P) of 66 Watts.

Abstract

This research focuses on improving hydropower production by designing a turbine for the MaliringanRiver in Kalimantan Selatan. The rotational speed and torque will be the focus of maximizing power generation. This research used Computational Fluid Dynamics (CFD) to understand how the fluid flows and how efficiently the turbine works. The simulations helped us see how the fluid flowed, the pressure differences, and the speed of the water inside the turbine. The software COMSOL Multiphysics imitates how the fluid behaves and interacts in real-life situations. The utilization of SOLIDWORKS played a crucial role in the turbine's design process, facilitating an accurate representation of the turbine's geometry and the subsequent fabrication of a prototype propeller turbine, featuring an outer diameter measuring 0.27 meters and an inner diameter measuring 0.113 meters. The methodology resulted in a power efficiency of 76.45%, showcasing the possibility of significant enhancements in the efficiency of hydropower generation. The broader ramifications of this study emphasize the feasibility of tailor-made turbines for local hydropower initiatives, thereby supporting Indonesia's renewable energy plan by providing sustainable and efficient energy alternatives. This study emphasizes the collaborative utilization of Computer-Aided Design (CAD) and CFD technologies in the progression of turbine technology, thereby establishing a basis for future investigations in hydropower optimization.
