Abstract

Commonly the prime material for brake pad of the commercial motorcycle using asbestos, these materials cause a disease like as cancer of respiration if the abrasive particles were sniffed. The SKJ (Serbuk Kayu Jati) brake pad is alternative to replacement the asbestos brake pads. The mechanical test includes a wear test, hardeness test, friction coefficient test, and heat resistant test. The hot press process for SKJ as main material of brake pad based by variation of temperature there are 160ºC, 170ºC, and 180ºC. The optimum test result of SKJ brake pads is a variation of 180ºC with wear test result is 3,36 x 10-7 mm2/kg, the hardeness result is 25,1 BHN, the friction coefficient test is 0,59 and not damaged on the heat resistant test with a temperature of 300ºC during an hour.

Abstract

Blade design and material selection for savonius turbines need to accurate to produce high power input. This research aims to make the most robust blade material by vacuum infusion manufactured. The hybrid laminate composite applied in the manufacture of Savonius turbine blades consists of woven carbon fiber with chopped strand mat glass fiber and woven glass fiber. The variations of fiber composition comprised of five layers, namely 5An (5 layers of woven glass fiber), 5Ac (5 layers of chopped strand mat glass fiber), 2C-3An (2 woven carbon fiber-3 woven glass), and 2C-3Ac (2 woven carbon fiber-3 chopped strand mat glass fiber). The results showed 2C-3An for the best variation of hybrid laminate composite with the tensile strength of 219 MPa, with the modulus of elasticity of 6.8 GPa and the smallest density was 1.21 g/cm3.

Abstract

Design of the red ginger powder production machine aims to increase UMKM(Usaha Mikro Kecil dan Menengah) in the Yogyakarta area. By making a semiautomatic red ginger powder machine, it can increase production capacity and improve the economy for UMKM. Component design is divided into 3 processes, namely; designing the frame, designing the stirring shaft, and designing the cooking tank. There are first adjusted to the design that has been made using the solid works software which is then applied by assembling other components. The drive system on the powdered red ginger production machine uses an AC electric motor which is then forwarded into the v-belt transmission then the output from the transmission is forwarded to the stirring shaft.

Abstract

The potential of natural resources in tropical countries is very diverse. one of them is the abundant agricultural products. but there are some obstacles in the post-harvest cycle and the continuous availability when the harvest season ends. various methods of preserving agricultural products have been tested from conventional methods to advanced technology. one of the technologies for preserving agricultural products is freeze drying. various innovations continue to be tested until they get consistent results with good energy efficiency. This method was originally started in the pharmaceutical industry. Various treatments and flexible adaptations make this method penetrate the food industry to maintain the quality of food products. In the food industry, freeze drying is suitable for food products such as meat, fruits, grains, and vegetables. The advantage of freeze drying is that the food products produced do not change shape, form, texture, taste, and nutrition even though they have gone through the drying process. Of the various characteristics of fruits and vegetables have their own properties that can be changed with the temperature parameters applied in the freeze dryer method.
