Abstract

This study explains what waste occurs in the manufacturing industry, where there are 7 wastes, namely excess production, waiting time, unnecessary transportation, excessive processes, excess inventory, unnecessary movements, and defective products. As a result of this waste, the company has lost an output of 46 tons in 1 semester. The purpose of this research is to find out the critical waste and the source of the waste that occurs in the manufacturing industry and then reduce the waste using the waste assessment model and the deming cycle method. The method used to identify waste is the waste assessment model. The waste assessment model consists of 2 stages, namely the waste relationship matrix to determine the relationship between waste and a waste assessment questionnaire to identify the causes of waste. The results of this study obtained critical waste from 7 wastes, namely defect waste with a percentage of 27.94% and the cause of the waste is the frequency of machine breakdowns that occur in area 2 production. It can be concluded that the critical waste in this research is defect waste that originates from engine damage in the production area and within a quarter the waste has been eliminated so that it can maximize the production process.

Abstract

Coffee is a farm commodity that has an important role in economic activities in Indonesia. The Indonesian coffee sector is dominated by small producers. North Toraja Regency, including in Sapan Village, is known as a producer of high quality coffee but low production. This study aims to examine the strategy of increasing coffee productivity in Sapan Village using value chain analysis. Data were collected through observation and interviews with cultivators in the value chain. This study shows that the productivity of coffee produced is still relatively low. The basic cause of low coffee productivity is that cultivation techniques are not good because information on good agriculture practices is still limited and there is a thought that the selling price of coffee is still low. To increase productivity, farmers need the role of the government. Farmers need counseling on coffee cultivation techniques that are in accordance with the application of GAP and price transparency from the government. If farmers have applied coffee cultivation techniques well, coffee productivity will increase so that farmers' income will also increase.
