Abstract

Drying technique plays a very important role in determining the quality and continuity of the tapioca flour manufacturing process. Traditionally the drying process is carried out by farmers by utilizing the sun's heat, but problems occur when the rainy season comes while production must continue to meet needs. which requires a large area of land and is very dependent on the weather with a lot of hot sun. Based on the analysis of the results of data processing using the Taguci experimental method to determine the optimum design of the main dimensions of the economizer in the laundry factory, the following conclusions are obtained. Effect of tube diameter, lay out, pitch ratio and excess area on the economizer Tube diameter (dO) has a significant effect on the amount tube and shell diameter (Ds).Picth ratio (PR) has a significant effect on shell diameter (Ds) but has no significant effect on the number of tubes. Excess area has a significant effect on the number of tubes but has no significant effect on shell diameter (Ds).Lay out has the same effect on shell diameter and tube number. Optimum economizer conditions. Optimum tube number ( Nt ) is obtained from a combination of tube diameter ( do ) 0.0254 m, excess area (PR) 1.2 , lay out 30o and pitch ratio 1 ,2. The optimum shell diameter is obtained from a combination of tube diameter (do) 0.0381 m, pitch ratio (PR) 1.2, excess area 1.2 and lay out 30o.Keywords: Dryer, Shell Diameter, Tube Diameter

Abstract

Technological developments that continue to develop today are increasingly making it easier for humans to do their jobs, as well as what is happening in the automotive world with the existence of these new technologies, it will make it easier for mechanics to do their jobs because of demands from consumers or desires and the mechanics themselves are constantly evolving. Knowing the effect of standard exhaust and modifications to the power and torque of the RX king 135cc motorcycle. This test was carried out using a dynotest tool, the influence of a standard exhaust and a modified exhaust of 2mm, 4mm, 6mm, and 8mm filter holes. produces the most optimal increase in power in the variation of the 2mm exhaust filter with a result of 16.6hp at 9059 rpm engine speed. As for the optimal torque performance, the standard exhaust produces a maximum torque of 14.43 Nm at 6289 rpm engine speed.Keywords: Exhaust, Power and Torque.

Abstract

Cassava is a tuber plant that can grow in tropical areas with hot and humid climates. In tropical climates cassava is needed for its growth process so that this plant cannot grow at temperatures below 10 c. Cassava is a tuber or tree root that can grow on sandy to clay soil, as well as on low-fertility soil. Cassava length ranges from 15-30 cm with a relatively different diameter as well, which is 2-5 cm. Cassava has a skin consisting of two layers, the first layer is the outer skin while the second layer is the inner skin with white or yellowish flesh. It would be better if the production of cassava cutting increased without ignoring the existing human aspects. Therefore, a machine is needed as a human tool in increasing the productivity of cassava cutting. Significant results or not, can later be observed from the data obtained before and after using the machine. A significant increase after the experiment was carried out means that the cassava cutting machine was able to assist the existing cutting process. This can be seen later by using SPSS calculations.Keywords: Cassava, Cassava Cutting Machine, SPSS

Abstract

To reduce production costs , designing a heat exchanger in advance is very effective than buying a ready - made exchanger . This design is in the form of dimensions of a shell and tube type heat exchanger using the polonomial power 4 calculation method and the calculation analysis method using the Exel program. Calculation of the dimensions of this heat exchanger aims to simplify the design and manufacture of heat exchangers. The heat exchanger designed is a shell and tube type heat exchanger which is widely used in Garment or Textile Companies in Pekalongan. The heat generated from the Diesel Exhaust Gas is 250 C - 300 C, where the exhaust gas originating from the Diesel is channeled to the heat exchanger so that the hot air released to the dryer has a temperature of 70C and the capacity of the dryer is 36 kg. /1 hour and Q = 1098 W and a temperature of 70 oC, so that the design of a heat exchanger is needed to circulate the hot air that has been raised in temperature. The exhaust gas that comes from PLTD with a mass flow rate of 2.72 kg/s, the design of a heat exchanger with shell and pipe type, where the flue gas heat flows through the shell and air through the pipe.

Abstract

Basically any engine that undergoes a combustion system to produce power allows for exhaust emissions. Exhaust gas emissions are the residue from the combustion of fuel (gasoline) and air in the combustion engine which is released through the engine exhaust system. Therefore, one of the efforts to reduce exhaust gas levels is to innovate to create a more perfect ignition system. This study aims to determine how the effect of the comparison of the ignition system Contact point, TCI and Full Transistor on the resulting exhaust emissions. The test was carried out using a gas analyzer on a Mitsubishi L300 gasoline with engine speed variations of 700 rpm, 1000 rpm, 2000 rpm and 3000 rpm to determine the concentration values of CO and HC. Based on the test results, it was found that the use of the TCI ignition system resulted in the lowest concentration reduction, namely at 3000 rpm engine speed with 1.43% CO levels and 115 ppm HC.Keywords: Contact point, TCI, Full transistor, Exhaust Emission
