Abstract

Wind energy is renewable energy that is clean, environmentally friendly and easy to obtain. Balikpapan City is very suitable for applying the Savonius wind turbine because it has a relatively low average wind speed. Savonius wind turbine is a turbine consisting of two concave and convex blades that work based on drag forces. Savonius wind turbine can utilize wind energy at low speed 2 m/s to be converted into electrical energy which can reduce the electrical load in urban areas. This research makes a prototype of the Savonius wind turbine with the addition of variations extra layer on the concave turbine blades. The test method uses a generator that is attached to the turbine shaft and the test is carried out in a multi-storey building area. The results obtained are the Savonius wind turbine prototype capable of producing actual power 0.76 Watt and power coefficient is 0.082. The addition of an extra layer at both tips of the turbine concave blades is proven to be able to improve the performance of the Savonius wind turbine.

Abstract

Currently, the dominance of electricity in Indonesian providers comes from fossil energy which has the potential to increase the average temperature in various parts of the world or is called global warming. The contribution of the national renewable energy potential mix in 2016 ranging from 6.27%, then reaching 11.28% in 2020. The Government has made a long-term plan for the national renewable energy mix to reach 25% in 2025 and 31% in 2050. One of the renewable energy sources is wind energy, which is usually built on a large scale and is separated from settlements so that a long distribution network is required. Conversely, on a small scale, wind energy can be utilized with a simpler distribution network, this concept is called Small Wind Turbine. For a good wind turbine is designed according to the wind characteristics in real-time, so it is necessary to study wind mapping. This research was conducted as a prelude to observing wind characteristics in the form of mapping wind speed and direction in real-time in the northern part of Balikpapan City Region, using the Automatic Weather Station instrument which was carried out August 6 to September 26, 2022. Data processing in this study using the Weibull distribution method with Microsoft Excel. This study shows an average speed of 1.118 m/s in wind conditions with high wind variability with strong gusts, with a power density value of 1.157 Watts/m2. The wind direction tends to be east after the wind gusts are blocked by the building profile.

Abstract

Leftover banana peels and orange peels are organic waste that can be used as a raw material for alternative energy in the form of biobriquettes. The high consumption of bananas and oranges in Balikpapan City has led to an increase in the amount of fruit peel waste, necessitating efforts to utilize this waste in a more optimal and environmentally friendly manner. This study aims to analyze the characteristics of biobriquettes made from banana peels and orange peels based on their calorific value, water content, and ash content, in accordance with SNI No. 1/6235/2000 standards. The research method employed was an experimental approach, utilizing varying particle sizes of 60 and 80 mesh, varying amounts of tapioca starch adhesive of 5% and 10%, and varying molding pressures of 2 tons and 4 tons. The stages of briquette production include drying, carbonization, charcoal refining, filtering, mixing the adhesive, molding, and re-drying. The study results showed that the best variation was obtained in 80 mesh briquettes with 5% adhesive and 4 tons of pressure, resulting in a calorific value of 6188.7 Cal/g, a moisture content of 6.27%, and an ash content of 7.42%. These results indicate that finer particles and higher molding pressure can improve briquette quality, as they produce a denser and more homogeneous structure, resulting in a more efficient combustion process. Meanwhile, excessive use of adhesive results in increased moisture and ash content and reduces the briquette’s calorific value. The results indicate that banana and orange peel waste have promising potential to be developed as a sustainable and environmentally friendly alternative energy source.

Abstract

This research is based on obtaining the best possible aerodynamic performance for the Quickster Narasena Bengawan UV Team Unmanned Aerial Vehicle (UAV) aircraft wing design. One factor that significantly affects the flying version of a UAV is the wing. The Quickster Narasena UAV aircraft wing uses an MH33 airfoil because MH33 is specifically for high-speed UAV aircraft. This research will compare the performance of a branch without a vortex generator with addition with a vortex generator. This study will also discuss variations in the positioning of the vortex generator on the wing of the Quickster Narasena UAV. The method used in this research is the Computational Fluid Dynamics (CFD) method. The simulation process will use the ANSYS Fluent 19.0 application with the K-Omega Shear Stress Transform (SST) method with the Reynolds-Averaged-Navier-Stokes (RANS) equation as the basis. This study aims to obtain the results of the coefficient of drag, lift, and the contour of the turbulence that will occur. The simulation results that have been done are the geometry of the wing with the addition of a vortex generator can reduce the drag coefficient and can increase the lift coefficient.
