XYZ is a company operating in the largest shipping manufacturing industry in Indonesia. Apart from that, PT. XYZ also accepts ship maintenance such as overhaul and ship repair work. PT. XYZ launched a ship created by the nation's children, named Ship X. This ship has a big impact because this ship can help provide medical assistance in underdeveloped, remote and frontier areas. However, in the production process of this ship there are still some remaining materials which can be said to be a lot. One of them is cable. To overcome this problem, analysis is needed to find out what factors can influence it and proposals that can solve the problem. In this research, the New Seven Tools analysis method was used. Based on the results of the analysis using the new seven tools method, it was found that the factors causing the large amount of leftover cable material were the lack of accuracy of both staff and field workers in determining material requirements and material processing. So that improvement evaluations can be carried out by determining the design and need for fixed materials in accordance with applicable SOPs, increasing worker productivity, and optimizing material processing during the production process.

PT Pertamina Gas is a big company that carries out transportation business or as a gas transporter through a transmission pipe. Gas pipes must be monitored regularly so that they do not experience damage, cracks, corrosion or even leaks. This research was conducted to analyze one of the pipe monitoring technologies, namely corrosion coupon monitoring to detect internal pipe corrosion using a failure mode effect (FMEA) method. Through fishbone identification, corrosion is classified into 6 factors, namely material (related to gas), method, people, machines, pipe facilities, and environment. Based on the FMEA method, it was found that the main cause of corrosion is material factors or comes from gas with a defect severity (S) value of 8, occurrence (O) of 6, and detection (D) of 3, with a total RPN of 144. With this research, it is hoped that the company can prioritize these causal factors and carry out corrosion control.

In the case of gas transmission, the calculation of the gas delivered and the gas currently in the pipe is of course required to be a safe amount in the sense of neither less nor more. A condition where the amount of gas is less than the minimum value of the pipe capacity can cause damage to the pipe because the pressure is below the normal point. Meanwhile, conditions where the gas in the pipe exceeds the maximum capacity value is also very dangerous because it can cause accidents such as pipe leaks and explosions. Therefore, this research was carried out to determine the value of forecasting gas demand by PT PGN to be able to find out the range of gas volumes that must be stored and then distributed by Pertamina Gas to meet PT PGN's demand. Forecasting is a technique of predicting the influence of prevailing conditions and situations on future developments. The method generally used in forecasting is the quantitative method using the time series method.

Domestic wastewater can be sourced from industrial activities, one of which is the Feedmill Industry. The Surabaya Feedmill Industry has been treating domestic wastewater using a WWTP. The management of domestic wastewater is based on the Technical Approval (PERTEK) of Wastewater Utilization for Application to Land. Based on the results, there are parameters that do not fulfill the quality standards. The parameter is Biological Oxygen Demand (BOD), an evaluation is needed to enhanced WWTP performance. The purpose of this research is calculating the percent removal of BOD, COD and TSS parameters in the biological treatment unit and identifying factors that can affect the removal of BOD parameters in the existing conditions of the biological treatment unit in the Surabaya Feedmill Industry. The method used is a literature study using the Ludwig Sasse equation. In the calculation of the average water discharge of 5.93 m³/day, only 29.6% of the planned discharge. The results of the calculation of HRT in biological unit processing have not met the design criteria, except for the aerobic biofilter. The BOD/COD ratio is 0.33. According to the existing calculation, the final result for the BOD parameter is 5.11 mg/L, COD is 24.38 mg/L and TSS is 37.33 mg/L. The design air requirement is 27.64 m³/day. Other factors that affect BOD removal are Dissolved Oxygen (DO) levels in the Aerobic Biofilter, nutrient requirements, and Food to Microorganism (F/M).
