To meet this shortage, farmers apply organic nutrient fertilizers as a substitute for non-subsidized and chemical fertilizers, but the process of making organic nutrient fertilizers requires a long fermentation process, which is 16-30 days. Therefore it is necessary to have an Anaerobic Bioreactor to help speed up the fermentation. This tool is quite expensive for farmers in Papungan village, so it is necessary to analyze the level of investment feasibility of the Anaerobic Bioreactor tool to find out whether it is worth buying or investing. From the calculation results obtained NPV (Net Present Value) of IDR 9,266,620, IRR (Internal Rate Of Return) of 40.1513% and BCR (Benefit Cost Ratio) of 1.0289 so it can be concluded that the purchase of Anaerobic Bioreactors is feasible.

T, which is a company in the automotive sector, uses the Min-Max method which aims to be able to better plan spare part inventory for customer satisfaction. This was motivated by the fact that the spare parts needed were not available, causing the car repair process to be delayed and cars having to stay overnight while waiting for the parts to be ordered and to arrive. From the results of data processing using the min-max method which has been carried out, it was concluded that the more often spare parts are used, the greater the minimum and maximum values when compared to spare parts that are rarely used. That there are 6 items out of 61 spare parts (0.1%) that are recommended not to have minimum stock or do not need stock because there has been no demand for parts for quite a long time. Meanwhile, for other items, it is recommended to stock at least 1 to meet existing demand. Apart from that, there are 5 items or 0.1% of spare parts with a maximum stock of only one because there is still demand, and 27 items out of 61 spare parts (44%) are recommended to have more than 10 maximum stocks.

One way to increase labour productivity is to calculate standard time. The standard time is the time required reasonably by a normal worker to complete a job that is carried out in the best work system. The research was carried out by direct observation in the field. Observation of the standard time that occurs through a certain time interval is useful for knowing the description of the use of queues. In this study, the population was operators working at PT Y at the time of the study, while the sample used was the total time of O-Ring installation. The analysis method used in this study uses the standard time analysis method using a stopwatch. Adjustments are made as a measuring effort to normalize the average price carried out by the operator. Adjustments are taken into account because operators in the work can do inappropriately, for example too fast as if in a hurry, encounter some difficulties, and other things. Time data collection was carried out 30 times by breaking down the work into three motion elements.
