Abstract

The community's conventional salt production business is one of the economic drivers of the community. In addition to being able to provide a lot of jobs for people in Indonesia's coastal areas, the people's salt production business is also seen as a way to reduce poverty. Pidie Regency, which is included in the Province of Aceh, is one area that has a wide coastline and can be utilized as a salt farmer business. Pidie is an area that has a salt production business with a total production of 449.05 tons/month. The problem faced in the traditional salt processing business in Pidie District is the unknown level of risk that exists in each salt production process. The purpose of this study is to determine the level of risk in the traditional salt production process using failure mode and effect analysis (FMEA) and probability impact matrix (PIM) in the Saho Adab people's salt business group in Keude Ie Leubeu Village, Kembang Tanjong District, Pidie District. FMEA is a form of qualitative analysis that assesses the severity , occurrence and detection on each activity and then given a value on a predetermined scale. Whereas risk assessment using PIM only assesses the severity and occurrence. Based on the analysis of failure and effect modes, the salt production process has a high level of risk, namely the packaging process with an RPN value (risk priority number) 75, the salt water storage process with an RPN value of 48, the drying process with an RPN value of 45 and the level of the soil process with an RPN 45. While the results of the matrix impact probability obtained by the salt production process that has a high level of risk, namely the process of storing salt with a value of 5, the packaging process with a value of 4, the process of leveling sand with a value of 3,5 and the process of salt water filtration with sand filtration media containing NaCl with a value of 3,5.

Abstract

The pharmacy is a place for the taking of drugs available at the Puskesmas Ingin Jaya, where in the process of taking drugs often there is a queue at certain times. This study aims to improve services so as to minimize the average waiting time for taking drugs while waiting in the queue and the service queue system so that the queue does not occur too long. The analytical method used is queuing theory analysis in accordance with the single phase single channel model or M / M / 1 which is applied to the pharmacy Puskesmas Ingin Jaya. The results of research on the process of taking drugs at the pharmacy Puskesmas Ingin Jaya by using queuing theory analysis, namely by calculating the queue model of one service line shows that in the non-rush hour condition, the number of facility lines used by one facility line is good, but not at the hour condition busy at 09.00-10.00, which shows that the longest patient waiting in the queue is 11 people, while the shortest queue is at 11.00-12.00, 9 people. The suggestion in this study is to add one service facility during the peak hour period, namely to become two facilities so that it is expected to optimize the performance of the service in the process of taking drugs.

Abstract

This paper uses the failure mode approach and effect analysis (FMEA) in formulating a risk reduction strategy for damage to critical components of the boiler section of the Nagan Raya steam power plant. Boilers are an important part of the production system of steam power plants. The problem in the boiler section is the relatively high damage frequency compared to other parts. The aim of this study is to propose a risk reduction strategy for critical boiler components using a failure mode approach and effect analysis (FMEA). The proposed damage risk reduction will prioritize important components that have the highest risk priority number (RPN). The strategy that was successfully formulated was for the cyclone separator component, to carry out periodic and scheduled preventive checks and maintenance, especially on the return leg to prevent the accumulation of solid particles in the fluid system. Primary air fans and induced draft fan components, they must perform standard operational procedures (SOP) when operating the fan so that they do not experience high vibrations, and routinely balance the rotor contained in the fan. As for the coal feeder components, monitor the coal flow in detail so that it does not accumulate at one particular point, which can cause leakage at the outlet flanges.

Abstract

This paper uses the Palmer method to schedule paving block production in CV. Nibo Corporation Banda Aceh. CV. Nibo Corporation is engaged in the production of paving blocks located in the city of Banda Aceh. Problems faced by CV. Nibo Corporation often produces excess paving blocks than the number of orders that results in product accumulation in the storage area. The purpose of this study is to schedule paving block production in CV. Nibo Corporation. Paving block production scheduling in CV. Nibo Corporation will use the Palmer method. This research begins by calculating each standard time for each job. From the scheduling results, the comparison between the initial factory work schedule is nine hours of work in one day, and twenty-four working days in a month. While scheduling using the palmer method is six hours of work in one day and twenty-four working days in a month, or nine hours of work in one work day and seventeen days in a month. Using the palmer method can reduce the difference in production and orders every month from 31.000 to 5.944, or 3.000 per month, thereby reducing the accumulation of paving block products.

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.
