Abstract

From the tofu production process. The waste generated by tofu industries can be divided into two types, i.e the solid waste and liquid waste. One effort to reduce the environmental damage due to tofu liquid waste from the processing of tofu is to make the tofu liquid waste into biogas. The effort to convert liquid waste from tofu factories into biogas reguires a biogas reactor.  The aim of this study was to design a biogas reactor with a size of 1 m3 (1000 Liters) by using materials and equipment that are very easily available in the market at an affordable price, to determine the pressure, pH value and the quality of the flame produced when the biogas is used as fuel gas stove. The method used in this study is an experimental method within 30 days. The results showed that biogas pressure increased with increasing time (days). Maximum pressure is reached on day 21, which is 12.2 kPa. The average pH value is 6.91. The temperature in the biogas reactor tends to be stable with an average temperature of 31oC. The color of the flame when the biogas from tofu liquid waste is used as a gas fuel for a large flame gas stove is still a mixture of blue and yellow. The utilization of tofu liquid waste into biogas is expected to reduce environmental pollution and make tofu liquid waste become a high economic value and environmentally friendly.

Abstract

One of the post-harvest honey processing processes is the pasteurization process. Pasteurization is the initial stage of honey processing before evaporation. The high demand for honey in Indonesia requires that honey producing companies must use pasteurization tools with large capacities and do not damage the honey content. Honey will be damaged if the pasteurization temperature is more than 70oC. In addition, the pasteurization process is also still a problem in the honey industry. Therefore it is necessary to make pasteurization tools with automatic and fast temperature control in the pasteurization process. The purpose of this study was to observe the rate of heat penetration into pasteurized honey material and the amount of honey weight pasteurized, then also measured changes in water content, viscosity, degree Brix, and density of density. From the results of measurements of heat penetration rates in pasteurization and conventional pasteurization devices, the difference in time duration on stoves 1, 2, and 3 to increase the initial temperature of 35 oC to 65oC respectively were 45, 45, and 42 minutes with a total of 101 honey, 22 kg while in conventional equipment takes 50 minutes to heat honey as much as 46,780 kg. Gas consumption on stove 1 was 0.291 g/(kgoC), stove 2 was 0.281 g/(kgoC), stove 3 was 0.285 g / (kgoC), whereas gas consumption on conventional stove was 0.272 g/(kgoC). The results of measurements of water content, viscosity, Brix, and density of density before and after pasteurization were as follows 21.99%, 4.835 poise, 63 obrix, 1.356 kg/m3, and 19.82%, 5.453 poise, 64 obrix, 1.358 kg/m3.

Abstract

This final project makes a device that produces electrical energy by utilizing waste heat from injection machines. The waste heat of the injection machine is converted into electrical energy using a thermoelectric. This device consists of an aluminum heatsink, aluminum plate, thermoelectric, MDF wood planks, engine gasket, and thermal paste. The heat generated by the injection machine is received by the hot side heatsink, then 4 units of the thermoelectric and the cold side heatsink. Thermoelectrics are arranged in series. The output from the thermoelectric is connected to a multimeter to test the amount of voltage and current generated. The number of thermoelectric-based equipment made of 2 (two) pieces and assembled in series. The test was carried out using an open circuit and a closed circuit with a load using a 1 watt LED lamp (Ω 55 Ω). The open circuit test results show that the largest voltage is generated at 10.80 volts with a hot side temperature of 108C and a cold side temperature of 64˚C. The results of the closed circuit test show that the greatest voltage produced is 2.64 volts with a hot side temperature of 108 C and a cold side temperature of 62 C. When thermoelectric based equipment is given a load, the voltage decreases because the voltage is divided into the given load. This equipment can be applied to turn on as many as 5 lamps with a power of 1 watt each which supports production activities in the injection workshop.
