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

Rectangular crossings with sharp turns have complex three-dimensional structures because the flow separation is caused by sudden changes in direction of flow in sharp turns. This study aims to determine the effect of variations in the width of the sharp channel solar collectors with hydraulic diameter factors to increase the heat transfer rate in solar collectors. The size of the collector examined was 2440mm x 1220mm in the form of a rectangular cross-section. Solar collectors use iron and iron gram absorber with a thickness of 30mm, the thermometer is placed on each track, channel, absorbent and output temperatur  of each solar collector. The results of the study can be concluded that the solar collector with the largest hydraulic diameter value of 223 cm will produce the highest output temperatur  and the temperatur  distribution at the collector can reach 91º C at 13.30. This is because the greater the value of the hydraulic diameter or cross-sectional area will increase the heat transfer rate.

Abstract

This research aims to study the mechanics (strength) properties of iron ore briquettes. Iron ore briquettes are made using the hot briquetted iron method (HBI). HBI is a briquette after reduction directly and pressed at a temperature above 650 ⁰C and has more density than 5000 kg/m3. The specimens used were iron ore briquettes made of the composition of iron ore, coal, and adhesives. The composition of the briquettes is 55: 40: 5, 65: 30: 5, 75: 20: 5, 85:10: 5 and the reduction temperature is 750⁰C,850⁰C,950⁰C and 1050⁰C. There are 16 briquett specimens. After the briquettes are made, the briquettes are reduced using a reduction blast furnance which is fuel by LPG and CO2 gas. When the mass of briquette is no longer decrease ore the time (reach steady state condition) the briquettes take out from the blast furnance for press. Pressing is carried out in hot briquettes conditions and the press load is 15 tons. The results obtained from testing the I-Type Tumbler Test have more small paricle ruptures because the briquettes have lost their adhesive during the reduction process and coal does not affect the strength of the HBI briquettes. After being reduced briquettes are given more adhesive so that briquettes can be tested again. Iron ore briquettes after reduction are stroger than those before reduction. In the variation 85:10:5 obtained from testing I-Type Tumbler Test iron ore briquettes test after reduction has a number of particle small rupture 0,21% while iron ore briquettes before reduction of 3,35%.

Abstract

Machining technology, especially for micro hole cutting cases is a challenge in the industrial world to supply for components that have micro dimensions. The purpose of this study was to measure dimensional accuracy (roundness) and burr formation in the part of the entrance and exit holes. The object of the material used is brass plate. Brass plates with a thickness of 0.5 mm will be drilled using a twist drill chisel 0.2 mm diameter made from tungsten carbide material. Spindle rotation speed varied is 14,000 rpm, 17,000 rpm, and 20,000 rpm. The variation in feed rate for each spindle rotation is 5 mm / min, 8 mm / min, and 10 mm / min. The hole from the results will be observed and measured using a stereo microscope. From the measurement results show that the size of the largest hole dimensions with a value of 0.217 mm is formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min, while the smallest hole diameter with a value of 0.202 mm is formed at a rotation of 20,000 rpm and a feed rate of 10 mm / min. The highest entrance burr value of 0.050 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.038 mm occurred at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The highest exit burr value of 0.077 mm was formed at a rotation of 17,000 rpm and a feed rate of 10 mm / min, while the lowest height of 0.032 mm was formed at a rotation of 14,000 rpm and a feed rate of 5 mm / min. The results of this research data conclude that the accuracy of the hole dimensions and burr formation becomes better as the spindle rotation value and machining feed rate increase.
