PT.S is a metal pressing company that produces spare parts for the automotive industry. The increasing number of new companies, encouraging the company to make improvements continously, one of which is by reducing the processing time. The problem that occurs is the frequent occurrence of late pulling stocks in the finished product inventory area. One of them occurs in the Cap product (C1805-009) within a period of 6 months (October 2017 to March 2018) 16 times the stockout in the finished product inventory area. In addition, an increase in demand requires companies to do various ways, including adding four inspectors on each shift. This study aims to analyze the flow of production processes and waste of time with a simulation approach. Based on the simulation results using the Promodel software, it is known that the work station that is the cause of flow congestion is the inspection work station. Proposed improvements in simulation results also showed improvements, namely the reduction of processing time by 330.66% and the reduction in the number of operators by 50%. The simulation results can be considered by PT. S to improve the flow of the Cap product manufacturing process (C1805-009).

The village of Karanganyar, at the regency of Indramayu, is the largest centre for walking catfish aquaculture industry in West Java. However, during 2015-2016, the growth of the catfish aquaculture has not been satisfactory, mostly due to several obstacles that reduces the production rate by 25%. Therefore it is necessary to map out an empowerment strategy for the aquaculture industry of catfish in the village of Karanganyar. The process of designing the strategy uses Internal-External Matrix (IE), analysis on Strength, Weakness, Opportunities and Threats (SWOT), and Quantitative Strategic Planning Matrix (QSPM). Early step involves gathering internal (strength and weakness) and external factors (opportunities and threats) for the aquaculture industry of catfish. These factors points to the factor that affects the development of the industry. Second step involves determining the empowerment strategy for the aquaculture industry of catfish in accordance to internal and external conditions using IE Matrix and SWOT analysis. Third step requires establishing a scale of priority for the prioritised strategy, which includes 1) forming a union of catfish farmer, 2) consolidate and reinforce partnership with institutions of higher education, supporting organisations, and other supporting institutions, and 3) developing capabilities of processing catfishes to satisfy demands from local and international markets. First strategy is expected to overcome the dependency on third parties for fishmeal, markets, and capitals, along with the difficulties for accessing financial institutions. Second strategy is expected to help with the development of the product, the improvement on the standardisation of aquaculture and post-harvesting activities of catfishes, and the step-up on levels of independency for farmers in terms of capital and funding. Third strategy is expected to grab the market niche and opportunity for catfish-based products in national and international scale by exploiting the ease of access to the market, the availability of training and supporting program for catfish aquaculture industries, and good ratings from customers in regard to the quality of catfishes produced by the industry.

Transportation is a sector that has a dependency on fossil fuel production and will produce carbon dioxide (CO2) emissions. Carbon Dioxide (CO2) is a pollutant produced by vehicles which causes air pollution. The increase in vehicle demand causes an increase in CO2 emissions, which is the cause of global warming. But vehicles with fossil fuels are still a necessity for community mobilization. Because most vehicles used today are fossil fuel vehicles, the measurement of the efficiency of fossil fuel use is very important. The measure used to see the efficiency of fuel use by vehicles is Vehicle Kilometer Traveled (VKT). By using mobilev software, carbon dioxide (CO2) emissions from fossil fuel vehicles can be predicted. CO2 emissions that occur in an industrial area are caused by several types of motor vehicles, namely motorcycles, LDV and HDV cars. From the analysis of the correlation between CO2 emissions with each type of vehicle obtained that the motor and LDV have a strong correlation with CO2 emissions, but the correlation with HDV is weak. This shows that CO2 emissions from each vehicle will contribute to CO2 emissions, the number of motorcycles correlates very closely with CO2 emissions (r = 0.9), the number of LDV correlates closely with CO2 emissions (r = 0.7) and the number of HDV correlates weakly with CO2 emissions (r = 0.1).

This research was carried out in a manufacturing company producing industrial paints for steel roofing and walling. The level of sales of industrial paint varies and fluctuates depending on product demand from customers. Due to fluctuating demand and forecasting methods for current product demand that is less accurate based only on demand from the previous period, the inventory of imported raw materials has not been optimal. The ARIMA method is used to forecast and then control imported raw material inventories using the probabilistic Economic Order Quantity (EOQ) method to determine the optimal order quantity, safety stock, re-order points and order frequency so as to minimize the total inventory cost. With the probabilistic EOQ method that implements the existence of safety stock will be able to minimize the risk of a shortage of imported raw materials so that the burden of shortage costs can be minimized. The results shows that the proposed method provides a total inventory cost savings of Rp.493,832,731 or obtained a 66% reduce cost compared to the company method

Chili (cabai rawit) is one commodity that is very significant for people's daily consumption. However, the price of chili often experiences a significant increase. This condition will make the sales of chili decrease dramatically if the price rises. In addition, the margins felt by farmers to sellers of chili in the traditional market are uneven. this is also felt by other vegetable sellers. This research aims to identify the supply chain network of chili in Bekasi Regency. The margin of each stage in the supply chain network is also identified. This research employs descriptive analytical. Descriptive analytics is a preliminary stage of data processing that creates a summary of historical data to yield useful information and possibly prepare the data for further analysis. Data collection method used is by direct observation in Bekasi regency and other locations associated with suppliers of chili, then we employ direct and a phone interview with respondents. The finding shows that there are three main stages in supply chain of chili in Bekasi Regency, namely producer, distributor and consumer. The consumers can buy the product from three channels, that shows the flows of product from producer to consumer. The share of margin in the producer stage for the second flow is lower than the first flow, with the value 56.25% from 75%, then, the third flow is higher than the second flow but still lower than the first flow, with the value 64.29%.

Quality is an assessment of products that are in accordance with customer specifications and relate to the level of customer satisfaction. Quality is one of the factors that influence the competitiveness of a product in the market. One indicator of the quality of a product is the presence or absence of defects (defects) of the products produced. In this study the DMAIC method was applied to solve the problem in the process of filling the 40 gram seasoning flour packaging on a single line machine at PT XYZ. The use of the DMAIC method aims to reduce defects due to the instability of the seasoning flour filling process which causes a mismatch of product weights to the specified standards. The improvement phase includes setting the machine by adjusting the distance between the cup and scraper on a single line machine and by increasing the number of sampling. Sampling the weight of the product that was previously only once every hour by the QC operator, added to the sampling every half hour by the production operator and once an hour is still carried out by the QC operator.

Spare parts are an important factor in the continuity of the production process for a manufacturing company. Its existence affects the company's operational processes. Besides, the inventory cost requires a large enough capital from the company's total capital. PT. ABCD currently has not applied the ABC method to determine the category of each part. This research was conducted by analyzing nine critical parts obtained from the ABC analysis results for the fast-moving category. The parts analyzed were focused on category A, with a fast-moving part value of 80.71% of the total existing parts. Based on Period Order Quantity (POQ) method, it was found that the total inventory cost applied by the company for the nine types of critical parts was IDR 37,054,735. In contrast, using the Economic Order Quantity (EOQ) method single order multiple products resulted in a total inventory cost of IDR 18 841,277, -. This result is better than the method established by the company, with savings of Rp. 18,213,458,
