Abstract

and eliminate waste. CV. Hidup Baru is a company that manufactures Bottled Drinking Water (bottled water) systems make to stock. The company set a number of production based on rough estimates of consumer demand in the previous periods. This causes the total production exceeds the amount of consumer demand for 6 periods within the range of the last 12 periods derived from historical data of the company. According to these data, too, can be seen an average of the final product inventory in the warehouse at 280% of the final product in each period. Stacking sizable inventory of this course will cause the cost of carrying cost is high. Therefore, this study aimed to optimize the amount of inventory in the warehouse by using the concept of lean manufacturing, in which the system uses the reorder point (amount of safety stock) as the minimum inventory that should be there in the shed, so companies can plan production quantities which should be generated in the next period. The results showed that with the proposed inventory system obtained total cost savings reached 716.100 cardboard carrying cost and inventory turnover value of 2 times is also larger than the current inventory system.Keywords: Lean Manufacturing, Safety Stock, Carrying Costs, Inventory Turnover

Abstract

This study used a rectilinear method in redesigning the layout of the salted fish production facility to minimize the mileage of Stefen Aluy's UKM. Stefen Aluy UKM is one of the salted fish businesses that is developing in West Aceh and its products are evenly distributed in West Aceh and its surroundings. The large production area makes it easier for UKM Stefen Aluy to maximize salted fish production. However, the large production area owned by UKM Stefen Aluy can result in long distances so that it is ineffective and efficient. The risk of worker fatigue and injury can occur due to the long distance. In addition, there is a risk of raw materials falling while moving. To minimize this potential, it is necessary to evaluate the layout of the salted fish production facilities at UKM Stefen Aluy, namely by improving the layout of the facilities. The rectilinear method can be used to minimize mileage in making layout improvements. From the results of the layout mapping based on the measurement of the rectilinear distance, the initial layout has a rectilinear distance of 6.932 cm, while the layout of the design results obtained a rectilinear distance of 3.409 cm. The result of the layout redesign resulted in a distance reduction of 49.04% from the previous distance.

Abstract

Agam Teknik is a business that produces dump trucks, where at the iron plate cutting site there are no work facilities that support operators in carrying out their work activities which result in complaints of skeletal muscles. In the production process activities, it was found that there were semi-automatic activities, namely the process of cutting iron plates using a welding torch on the floor so that the operator worked in a squatting state, bent knees and ankles, raised shoulders and bent body so that the work posture experienced by the operator was not ergonomic. The aims of this study were (1) to identify complaints of musculoskeletal disorders experienced by dump truck manufacturing operators using the Standard Nordic Quistionaire (SNQ), (2) to determine the value of the operator's work posture using the REBA method with the help of Ergofellow Software, and (3) to design ergonomic work facilities. SNQ is a method used to identify the source of muscle fatigue at work, while the REBA method is used to determine risk factors related to overall body posture at work. The tool used is Ergofellow Software which serves to analyze quickly and easily in terms of postural. The results of the identification of operator complaints during the dump truck manufacturing process, obtained two work stations where the operator felt very sick and painful complaints, namely at the cutting station and pressing the iron plate. Based on the identification results obtained eight operator complaints, namely extreme pain and pain including pain in the left and right shoulders, neck pain, left upper arm pain, back pain, left hand pain, right knee pain, left calf pain, and pain in the right leg. Recommendations from these conditions are to design an iron plate cutting work facility with the addition of a table for cutting iron plates, and to redesign the iron plate pressing station by adjusting the press tool used by the operator for pressing iron plates.
