Abstract

Cassava is one of the animal feeds, namely poultry and fish feed, etc. Its use is very beneficial for farmers easily to get this material. The processing of cassava is by chopping small cassava by chopping manul. This method is felt to be less efficient for a large amount because it will take a lot of time and energy, so by making the solution with a wake up design. in this design, it is devoted to the calculation of its components. In this design, the power used is 3.519 kw with a 2000 rpm engine speed, turning a 40 mm shaft using a 3 inch pulli 4 inch pulli with a 1500 rpm dish rotation using a V type A belt, with 9 blades in the tube.

Abstract

Shovel is one of the important parts in the clay grinding machine component, where this component serves to direct the material that is milled in the mill between the roller and roller bearings. With the high rate of replacement of this shovel material due to wear will have an impact on the decline in engine productivity due to lost working hours. Shovel material is made from Hardox 400 material where the value of BHN material hardness: 370 - 430, the value of material hardness is very influential in determining the age of the shovel, but still calculated from the side of the collision load that occurs during grinding. From the results of testing both macro testing and micro testing it is known that the value of material hardness (Hardness test) is not in accordance with the specifications of the material which is around 37% below the specification value. And from the SEM test results it can also be observed that there has been a significant change in the grain structure of the matrial surface and scouring on the shovel samples that have been used.

Abstract

In the process of processing cassava chips, especially chili chips made by the patumbak village community, ranging from stripping, washing, chopping, soaking and packing still use human labor and are done manually with simple tools. So that this problem can be overcome, the solution is to have designed and made cassava chopper machines. The purpose of this PKMS is to help solve the problems faced by small home industries with Appropriate Technology independently in the village patumbak, village. The implementation method begins by examining the technological and equipment deficiencies in the processing of cassava chips, especially the cassava chopper machine. During this time the process of chopping cassava before being fried into chips is done manually. The method used to achieve the PKMS goal is to make a cassava chopper machine in the village of Patumbak. The results obtained are that the PKMS activities have been completed by the team for 1 period of activity, the final result has been obtained the application of appropriate technology in the form of cassava chopper machines in partner villages and partners was greatly helped by these activities. From the activities that have been carried out the last questionnaire score that has been distributed to partner villages is the highest score influencing the results of understanding of the community or partners, where PKMS 2019 partners are satisfied and helped by the existence of the abdimas. The final result that has been obtained is the production of cassava chips increased by 50% when compared to before the team came to do PKMS activities, the condition of this improvement was seen after partners used cassava chopper machines from the PKMS team.

Abstract

Mesin penggiling sekam padi adalah mesin yang digunakan untuk proses penggiling sekam padi. Dengan menggunakan batu gerinda yang terpasang pada poros digerakkan oleh motor. Pengujian ini bertujuan untuk mengetahui pengaruh variasi putaran batu giling terhadap produktivitas. Mesin yang diuji berkapasitas 30 kg/jam. Dengan menyiapkan mesin penggiling sekam padi dan alat uji yang digunakan kemudian bahan baku yang digunakan adalah sekam padi kering dengan density 0,902 kg/liter dengan ukuran rata-rata panjang 3 mm dan diameter 1-1,5 mm. Dari hasil pengujian ini ternyata diperoleh kapasitas 23,4 kg/jam yang bekerja pada putaran 992 rpm, sedangkan pada kapasitas 24,6 kg/jam yang bekerja pada putaran 1097 rpm, kapasitas 34,2 kg/jam yang bekerja pada putaran 1457 rpm. Kualitas yang didapat pada putaran 992 rpm yaitu 59% sekam halus dan 41% tidak halus, sedangkan pada putaran 1097 rpm yaitu 63,4% sekam halus dan 36,6 tidak halus dan pada putaran 1457 rpm yaitu 60% sekam halus dan 40% tidak halus. Effisiensi daya dan daya produksi yang dihasilkan pada putaran 992 rpm, besarnya effisiensi mesin 34,6% dengan daya 1733 Watt didapat daya produksi 74,05 Watt/kg, sedangkan pada putaran 1097 rpm besarnya effisiensi 33,3% dengan daya 1800 Watt didapat daya produksi 73,17 Watt/kg dan pada putaran 1457 rpm, besarnya effisiensi mesin 30% dengan daya 2000 Watt didapat daya produksi 58,47 Watt/kg. Kata kunci : sekam padi, putaran, batu giling, efesiensi
