Abstract

Wind energy is one of the energy that is starting to be used to produce electricity or convert it to mechanical energy for other purposes. One of the tools used to harness wind energy is a wind turbine. Indonesia, especially Aceh, is one of the countries that has not used wind energy as a power plant because of the characteristics of wind in Indonesia which tends to be low-speed. Archimedes spiral wind turbine is a new type of wind turbine that can operate at low wind speeds, consisting of two to three Circular blades form an axis, then wrapped around each other and one side is extended, the design of this turbine essentially mimics the shell of the Nautilus snail (Biomimicry). The basic principle of this wind turbine is designed using the legal principle of Archimedes. This scientific work will analyze the effect of variations in the number of blades on rotation and the influence of blade rotation on wind speed using the experimental method, therefore turbines are made with variations of 2 blades and 3 blades, and the outer diameter is 80 cm and overall length is 90 cm. From the results of the study it was found that the 3 blade wind turbine has a better percentage of shaft rotation compared to the 2 blade wind turbine that is equal to 16.67%. Maximum wind power occurs on the 4th floor with a value of 164.3 watts

Abstract

A hydraulic ram pumps, or shortly known as a hydram, is a water-lifting device that operates automatically and continuously. It is a device that uses the energy in the flowing water such as spring, stream or river to pump part of the water to a height above that of the source. With a continuous flow of water a hydram operates continuously with no external energy source. Hidram pump design influenced several input parameters such as head, inlet pipe diameter and yield parameters: length of inlet pipe, heavy weight exhaust valve, the inflow speed, output flow rate and efficiency of the pump. In this study, the analysis is done using visual basic 6.0 computer program, as well as completion of the problem in terms of design of the hydram pump. The performance results are then compared with the experimental results. This program aims to ensure that everyone can design and make the hidram pump, with still follow the general rules of the proper design.

Abstract

Micro hydro Power (MHP) Rampah planned to power as many as 95 heads of house holds with an installed power capacity of 20 kW. Source water comes from rivers by building dams Rampah intake. Intake should be on the basis of a steady stream, so it does not impede the flow of water entering the intake. The writing is focused on the stability of the river going up stream along the 300 m intake, based on the difference between the two cross-sectional sediment capacity in each pias. Stream flow that occurred during measurements of 5.724 m3/sec. Debit is used to drive a 50% of the measured discharge, so the available flow is 2.862 m3/sec. This exceeds the initial survey of potential discharge stream Rampah required to drive the turbine at MHP Rampah of 1.5 m3/sec. Calculation of sediment using Frylink method. Turns on up stream erosion, so that down stream erosion, while experiencing the process of deposition of sediment down stream. Debit dominant flooding that occurred in September 2011 until February 2012 amounted to 9.833 m3/sec and a maximum flood discharge of 19.572 m3/sec. While the discharge monitoring using arc discharge regression equation Q = (3.142 H - 0.289)2. In the circumstances the magnitude of dominant flood sediments (bed load) that settles and into the intake tract of 0.00019 m3/sec, while in a state of maximum flood 0.00035 m3/sec. Minimum grain diameter (smallest) as the protector of the river at flood dominant at 21.50 mm, and maximum flood conditions used by 31.00 mm.

Abstract

The availability of fossil fuels is increasingly decreasing, so some researchers have to look for alternative fuels, namely biodiesel. The raw material used as biodiesel was avocado seeds planted in Indonesia. Avocado seed oil content ranges from 15-25%. The purpose of this study was to determine the characteristics of biodiesel and diesel engine performance testing. This biodiesel is obtained through the esterification and transesterification process. This research uses a mixture of avocado seed oil biodiesel fuel with Pertamina dex fuel namely (B-5) 5%:95%, (B-15) 15%:85%, and (B-25) 25%:75% and (B-0) as a comparison. The test was carried out at the Engine and Propulsion System Laboratory at Mechanical Engineering Department, Universitas Syiah Kuala. The diesel engine was used is RUGGERINI HT-51 with a maximum power of 3 kW/3600 rpm. Biodiesel from avocado seed was tested physicochemical characteristics; the result is in accordance with National Standard (SNI) for biodiesel fuel. Performance results show the B-15 fuel produces the best engine performance at 3500 rpm. At this cycle a maximum power of 1.90 kW is obtained, the lowest specific fuel consumption rate of 2000 rotation (rpm) is 0.34 kg / kW hour on B-15 fuel, and the highest thermal efficiency on B-15 fuel with 2000 rotation (rpm) is 14.05%.

Abstract

The function of solar collector is to increase the air that consist of absorber, air duct and glass cover. One of the factors that affect the collector output temperature increased is depend on high temperature absorber. An absorber serves to absorb heat from the sun, and heats flowing air in the air duct above the absorber. The heating of the air pass/route is greatly influenced by the flow patterns inside the collector. In this study the authors examined the use of variations absorber on solar collector. There were four variations of The absorber; iron sand, gram iron sand, asphalt hotmix, and iron sand asphalt. The research method is intended to determine the value of heat transfer by radiation, conduction and convection. Dimension of solar collector was used 300 cm x 80 cm. The best variation of absorber was gram iron sand type at the most optimum intensity of sun at 12 a.m-2 p.m.

Abstract

Thermal energy is one form of energy that is very crucial for human being. It can be obtained through the sun, i.e, that is solar energy. Solar energy is used widely both in industry and houshold. One of the most important component of solar water heater is thermal energy collector or known as absorber. Solar collector is a device utilized to convert sun radiation to thermal energy. This research wanted to examine the effect of different shapes of collector. The methodolody used is by varying the shapes of plat plate, where plate A has a square shape and plate B has has isosceles shape. Collector dimension is 1.5x0.8 m with these two shapes constructed from stainless steel. Pipe used for fluid is made from copper with 1 in diameter and 1.4 m length. Thermal insolation is used from rubber to decrease heat loss from pipe. Plate B collector with isosceles shape showed the highest efficiency compared to plate A collector with square shape. The highest outlet fluid temperature from plate B is 670C with sun radiation 1198 W/m2. The highest useful energy is 209.91 Watt from plate B at 13.30 and efficiency is 16.23% at 13.00WIB.
