Abstract

The R 175 diesel engine is powerful enough to drive most agricultural and plantation equipment, fisheries, and even electric generators. An example of its application in SMEs in the Sukoharjo Regency area of ??Central Java Province is processing clay mixers and printers in tile SMEs.The main problem today is that the use of the R 175 diesel engine is known not to last long or not last long; some even say it burns easily (smokes black) and is difficult to start (starting the crank), and the rpm is unstable. The main cause is the quality of the fuel misting system in the injector, which is not perfect (sometimes even dripping or clogged), only produces a mist diameter of 40mm, and uses biodiesel fuel. The aim of this research is to determine the value of increasing fog formation through optimization of the Taguchi orthogonal array L9. This research method is experimental by applying 4 factors and 3 levels to the response to the formation of fog diameter. The injector mist diameter data was subjected to statistical analysis of the Signal Noise Ratio Larger The Better (SNR LTB) and the effect value of each factor. The research results show that the value of increased fog formation achieved by the R 175 driving engine was 27.84 mm, or an increase of 68.74% from the initial condition of 40.5 mm to 68.34 mm. The factor level composition that produces the optimal fogging diameter is test number 3 A1B3C3D3, namely the fuel viscosity value using dexlite, pump lever distance 20cm, pumping time 15 times/30 seconds, nozzle setting +3 revolutions.

Abstract

Nila fish is a food source containing animal protein, which is important for human health. The health of nila fish is the main factor that is prioritized by a number of cultivators and livestock breeders. The more quality air in the pond, the more stable the pond temperature will be, and the fish growth will accelerate. The air source comes from nature and is artificial, using a water wheel. The main problem is that the driving engine resource is quite large, 1 pk, which increases operational costs. This activity has the main objective of applying the energy-saving horizontal water mixing technique in fish pond cultivation. The method applied is observation of needs and problems, followed by design and manufacture of tools, and ending with periodic evaluation. The result achieved is that a 1/5 pk energy-efficient water wheel using a gear transmission is able to increase the quality of oxygen content in the tilapia pond.
