<![CDATA[Guwatirta Sejahtera is one of the companies engaged in the bottled drinking water industry. Problems that occur at PT. Guwatirta Sejahtera is the absence of routine maintenance on the machine so that damage, especially on automatic bottle filling machines, often occurs. This study applies a total productive maintenance method to determine the level of damage and identify the source of the problem as a basis for making recommendations for improvement in reducing the level of damage that often occurs in automatic bottle filling machines. The stage of the study begins by determining the engine efficiency and six big losses using the Overall Equipment Effectiveness parameter (OEE). Then proceed with identifying the source of the problem using the Failure Mode and Effect Analysis (FMEA) method. Recommendations for improvement include making: a daily inspection checklist, small working groups, Standard Operating Procedures for operating the machine and routine maintenance schedules. Based on the estimated calculation if the recommendation for improvement is applied, the value of the original engine efficiency of 84.26% increased to 98.97% and the initial maintenance costs of Rp.81,232,369.48 decreased to Rp.75,355,764.39 per year]]>

<![CDATA[The most widely generated waste is organic waste, which is 60% compared to other types of waste. So far, NRC has been able to process organic waste to be used as animal feed products for catfish or pellets. The production capacity that can be carried out by the NRC company is 150 kg to 200 kg per day, but the organic waste obtained at this time has not been able to reach the required production capacity. Based on this, it is necessary to propose a better organic waste supply chain model for NRC companies. The purpose of this study will be to map the supply chain of organic waste into catfish feed. The supply chain model made is the current supply chain and the proposed supply chain. The final output of the study will compare current conditions and proposed supply chain models. The simulation results with arena software show the acquisition of organic waste as much as 352 kg. That means organic waste obtained by the NRC company from the 4 waste banks is 352 kg. Recommended supply chain recommendations have 4 waste bank suppliers, with each bank having a minimum of 3 waste producers.]]>

<![CDATA[Musculoskeletal disorders (MSDs) are diseases in the human muscular tissue system in the back, wrist, knees and shoulders caused by incorrect postur during work activities. This study was conducted to determine the level of risk MSDs on operator work activities at the cast house work station. Activities under study are activities; surface repair tap hole, checking temperature iron, and take iron sample. These activities are carried out repeatedly, incorrect work posture and the presence of heat from work environment factors that affect the whole body. This makes the operator complain of pain in parts of the body at risk of developing musculoskeletal complaints. This study was an observational study using the Rapid Entire Body Assessment method and the Nordic Body Map instrumen. The result of the Nordic Body Map instrumen for 20 operators at the cast house work station showed that there were 21 complaints against operator. Based on the measurement of cast house operators the surface repair activity of tap holes has a “high” risk value for MSDs (REBA Score 9), checking temperature iron activities have a “low” risk value for MSDs. Proposed improvement to prevent is to improve the procedur in the surface repair activities of tap holes, where when the process of sticking the dough is done in front of the tap hole is changed by attaching it to the mud gun nozzle tip. After the proposed improvement, the result of the Nordic Body Map instrumen showed no complaints and the measurement of the tap hole had a “low” risk value for the occurrence of MSDs (REBA Score 3).]]>
