<![CDATA[With the decreasing of world oil reserves, energy savings programs have started across the entire world. Recently, Indonesia has now become one of the importing countries for crude oil. Biomass gasification sustainability, especially in Indonesia, is very guaranteed because of the abundant availability of biomass in Indonesia. The goals of this study are examine the 5 kW diesel generator performance against various load with diesel fuel and diesel fuel plus syngas (synthetic gas) from sawdust. This research was carried out at Renewable Energy Laboratorium of Engineering Faculty UNTIRTA. The author performed this research using 5,2 kW total load of halogen lamp. In this research the load used was only at 3.2 kW because of the "not optimal condition" of the diesel generator resulting in not optimal engine rotation. Diesel generator power value at low loading point was increased. Whereas, at high loading point was decreased.]]>

<![CDATA[Sebagai salah satu turunan produk dari aren, gula aren cair memiliki pangsa pasar tersendiri yang menjanjikan. Pengolahan nira cair selama ini masih menggunakan metode tradisional dengan pemanasan diatas 120C dimana proses ini menyebabkan proses Reaksi Maillard yang berlebih yang bisa menyebabkan kanker. Penelitian ini menciptakan proses pengevaporasian kadar air melalui proses pemanasan dibawah 100 C melalui proses vacuum evaporasi. hasil eksperimen menunjukkan bahwa tekanan vacuum sangat berpengaruh pada temperatur didih air, pada 0,24 Atm proses vacuum evaporasi dapat mengurangi hingga 80% kadar air dalam waktu 9 jam, selain itu produk gula aren cair yang dihasilkan berwarna lebih muda dibandingkan produk proses secara tradisional. Kata kunci: Vacuum Evaporator, gula cair]]>

<![CDATA[The availability of fossil fuels is prolonged, declining. This causes the need to find alternative fuels is increasing. Based on this, the study discusses alternative fuels from rice husk biomass. The method to do is to process the biomass energy through the gasification process in the reactor, and vary the value of the combustion air velocity through the configuration and manometer output tubes, and the water content content of the rice husk, with the result in the form of synthetic gas. The purpose of this research is to know the effect of speed variation of fuel combustion air to syngas content, heating value (LHV) efficiency of synthetic gas and gasification. The results showed an increase for both CO and H2 compounds in water content of rice husk 8.33% and 10.28%. This result is also proportional to the increase in the heating value (LHV) of the synthesis gas produced by the calculation approach. And the overall efficiency of the gasification process is best obtained at the air velocity value of 14.9 m / s with a value of 45.95% in the moisture content of 8.33%.]]>

<![CDATA[Wind is moving air caused by the earth's rotation and also because of the difference in air pressure around it. The wind flows that occur include laminar flow and turbulent flow. Judging from the effect of spreading its direction, the wind that passes through a building, its flow will split into horizontal and vertical axes and pass along the geometry and structure of the building. This happens because the wind speed increases due to the increased wind pressure along the side of the building. Departing from this hypothesis, this research was conducted to compare the velocity potential on the angle side of the building roof with the speed at the top of the building (Rooftop) as a starting point for the development of new renewable energy engineering, especially wind energy. This experiment was conducted at the Dean Building of the Faculty of Engineering, Sultan Ageng Tirtayasa University, Cilegon, Banten. After conducting experiments with reference to the International Electrotechnical Commission (IEC) 61400-12-1 standard, this research found that on the angle side of the building the average and maximum velocity are higher than those on the roof of the building, also the wind energy potential is higher, amounting to ≥20.94%. In terms of Daily Wind Energy Potential, the elbow side of the building is proven to be more efficient with an increase in efficiency of 42.2%.]]>

<![CDATA[Sultan Wind Turbine is a vertical type wind turbine researched by New Renewable Energy Lab which is used as development for wind energy utilization. In this wind turbine, there are problems in the form of blade resistance which is not strong enough to withstand wind velocity when the wind blows reaches 4 m/s. The blade, which is one of the parts that have the highest liability on the turbine, can be improved in terms of performance and their overall strength. The blade material which currently used is fibreglass, and Styrofoam can be substituted using a better material to improve its performance. Carbon fiber and ABS filament can be substituted as a blanket and airfoil to be used as materials for manufacturing new blades. This research will focus on improvised blades in terms of performance and strength. With an experimental and quantitative approach, the data obtained from the blades that have been improvised with carbon fiber and ABS filament, resulting in blades that are superior from their predecessors.]]>
