Rancang Bangun dan Analisa Mesin Pengaduk Dodol Semi Otomatis dengan Kapasitas 30 Kilogram

Abstract

Dodol is a traditional food that is quite popular in some areas in Indonesia. Dodol is one of processed agricultural products were included in the types of food that have a wet texture so that it can be eaten without rehydration and dry enough so it can be stable in storage. Dodol including intermediate moisture type of food which has a water content of 10-40%; Aw 0.70 to 0.85; soft texture; elastic, can be eaten, does not require refrigeration and durable during storage. The process of making dodol traditionally takes 5-6 hours and requires 2-3 employees. Problems faced by the small and medium enterprises, especially the small industries of rural households, included a lack of experience, poor education, limited capital, inexact selection of location, low competitiveness, outdated equipments and products, less follow the information and developments. These conditions encourage the author to make dodol mixer used to assist and facilitate the small and medium enterprises in making dodol that meet the needs, ideal for small industries, with a simple shape and easy to operate. This machine is driven by an electric motor. The research result of belt analysis indicate that an error occurred selection of the type pulley on the second and third belt, where in the second belt, according to calculations should use a belt type C but the type of belt used on the appliance is V-belt type B. The same thing happens on the third belt where according to calculations should use a belt type E but the type of belt used on the appliance is v-belt type B. While for the first belt, the use of v-belt has been in accordance with the calculation, which the belt used is a v -belt with type A.
