The purpose of this research is to analyze the problems in the production process in the occurrence of waste. This method used lean six sigma approach to define, measure, analysis, improve and control (DMAIC). The results of the study were the ability for saus sambal to be at level 3 sigma, while the shrimp sauce was at level 4 sigma. The analysis found two waste production process. First, waste transportation, is in the form of activities to move the labelling table and the labelling table is placed close to the pallet during the packing process. The second is waste processing in the form of sorting activities and manually re-stripping the raw material in the compounding process. As for the improvements suggested by the researchers, the first is to improve the packing area layout and use conveyors to move the cans to be packed and the second suggestion is to standardize Rpm and the appropriate amount of release rubber to produce optimal fresh raw material peels.
This research was aimed to study alternative techniques for soil conservation in controlling erosion and nutirients lost from Andisol planted with potatoes in upper part of Merao watershed, in Kerinci Region, Jambi Province. The research was conducted in Kebun Baru, Kayu Aro, Kerinci. The soil and sediment samples were analysed at Soil and Land Resource Laboratory, Agriculture Faculty, Institute Pertanian Bogor. Erosion was measured on small plots consisting of seven (7) treatments and three (3) replications considered as blocks. The results showed that planting potatoes across the slope direction, or making soil bed across 15% slope, or soil bed as slope direction and across slope direction every 4.5 m distance could control erosion and nutrients lost, and did not affect potato yield compared to soil bed as slope direction. Planting potatoes on soil bed as slope and across slope direction in each 4,5 m distance (modified farmers model) reduced erosion, soil organic-C, and total-N lost for 65.89, 65.19, and 24.55%, respectively, compared to planting as slope direction.
The purpose of this study is to conduct a quality control analysis of carded and combed yarn produced using the six sigma method. The approach used in working with the Six Sigma method is DMAIC (define, measure, analyze, improve and control). The results is obtained from the carded and combed yarn products are there are 4 types of defects, such as the strength of the thread does not match the standard, contami, bad rolls and tangled thread. The average DPMO value is both threads of 7,786 with an average sigma level of 4. The root causes of product defects are operators’ fatigue, age of machines, no machine checks, cotton fibers from the eastern countries and lack of ventilation. The conclusion obtained by using the DMAIC (define, measure, analyze, improve and control) to analyze 4 types of strength defects is that the strength defects do not match the standard is the most dominant type of defect. In addition, the results of the DPMO value and sigma level indicate that the product quality is good, exceeding the average sigma level of the company in Indonesia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
