Abstract

A production process will not be free of difficulties with faulty goods during its implementation; this is a problem that is a major factor in the production process; if the process still has many problems with product defects, the process has not been adequately regulated. Moving on from the issues raised above, the author did research at UD. Meurah Mulia, a paving stone manufacturer. For the time being, the control process in the manufacturing process is inspection control, which is an inspection that just distinguishes good and faulty goods without improving the process. In this scenario, the authors advise using the Six Sigma approach to eliminate flaws, which is a process control method that can affect decisions connected to product manufacturing, namely the production and insfection functions. The results of the analysis through processing with the Six Sigma method, which goes through five stages, namely define, measure, analyze, improve, and control, show that the current control process is ineffective, as evidenced by the occurrence of numerous defects in the manufacturing of Paving Blocks.

Abstract

UKM Stefen Aluy is one of the businesses engaged in processing fresh fish into salted fish. When conducting preliminary research in the field, several causes of Musculoskeletal Disorder (MSDs) complaints were found. The results of the preliminary study, 66.7% of workers complained of pain in the waist, 50% of workers complained of back and waist pain, 33.3% of workers complained of pain in the left and right elbows and 16.7% of workers complained of pain in the thighs. Cumulatively from the preliminary research conducted, the parameters of the level of pain complaints were 21.4%, moderate pain, 33.3% and 45.2% pain. If this condition is ignored continuously for a long time, it has the potential to cause injury or low back pain to workers. To identify and analyze work attitudes, the Ovako Work Analysis System (OWAS) method is used, which is a method to identify and analyze work attitudes. The results of the study concluded that based on biomechanical measurements of work postures, there were several work postures that were included in 3 (three) assessment categories, namely the work posture of moving fish at the sorting station, working posture of moving fish at the weeding station, and working posture of moving fish at the packaging station.

Abstract

This study aimed to analyze the operator's work posture using the Rapid Entire Body Assessment (REBA) method and to determine the level of risk of Musculoskeletal Disorders (MsDs) on the alum filling station operator at PDAM Tirta Meulaboh. Based on the observations made on the operator's activities while working, the operator fills the alum with a bent body position, uses a shovel and lifts it and is done repeatedly. This research is a quantitative descriptive study, with direct observation of the process of filling alum. Data collection is done by taking photos of the operator's activities while doing his job, then determining the angle of the operator's body using the Rapid Entire Body Assessment (REBA) method. The conclusions is that the operator's working posture with REBA method gets a score for element I with a score of 6, element II with a score of 8, and element III with a score of 7 and the level of risk through Action Level. REBA score element I final score (4-7) moderate risk category with required action, element II final score (8-10) high risk category with urgent action required, and element III final score (4-7) moderate risk category with required action.

Abstract

Telapak tangan minyak adalah salah satu perkebunan yang memiliki peran penting bagi sub sektor perkebunan. Produktivitas tandan buah kelapa sawit meningkat dengan cepat dan mencapai maksimum pada usia 8-12 tahun, kemudian menurun secara bertahap hingga usia 25 tahun. Kelas kesesuaian tanah dapat mempengaruhi produktivitas kelapa sawit. Penelitian yang dilakukan di Divisi II Kebun Matapao Pt. Socfindo. Ini dilakukan pada Mei 2021 hingga Juli 2021. Penelitian menggunakan analisis deskriptif, menggunakan produktivitas data kelapa sawit di Divisi II Kebun Matapao. Hasilnya menunjukkan bahwa jumlah rata -rata tandan per pohon pada tahun 2011 hingga 2013 meningkat 1,49% dari potensi, berat rata -rata tandan menurun 5,82% dari potensial, dan produktivitas rata -rata tikat buah kelapa sawit menurun 15,10% dari potensi. Kesenjangan produktivitas kelapa sawit di Divisi II Kebun Matapao Pt. Socfindo dipengaruhi oleh faktor iklim, usia faktor tanaman dan jumlah pohon per hektar.

Abstract

CV. Rasya Jaya is a traditional fishing boat manufacturing company located in Padang Seurahet, Kec. Johan Pahlawan, Aceh Barat Regency. The facility layout of CV. Rasya Jaya has several workstations that are not in the correct location for the production process or the relationship between related rooms. This results in inefficient and ineffective material handling, as well as reduced worker comfort. The poorly organized facilities also contribute to production constraints. Therefore, it is necessary to evaluate the production facility layout at CV. Rasya Jaya. The goal is to provide an alternative design for the production facility layout that is more efficient and effective in terms of the relationship between the production process flow and minimizing material flow in the production process. The purpose of this study is to determine the optimal layout at CV. Rasya Jaya using the Blocplan algorithm. Blocplan-90 is an algorithm for solving spatial layout problems that can handle both quantitative and qualitative data. Mathematical models within the design are developed with computer applications for models that work with the limitations of workstation shapes. Based on the results of the layout design of facilities at CV. Rasya Jaya, three main layouts were created: office layout, facility layout, and production layout. The total area of the three layouts is 1739 m2.

Abstract

CV Nadha Furniture is a business entity operating in the furniture sector which produces various types of processed wooden goods that have sales value such as doors, frames and windows. The aim of this research is to identify potential hazards at each step of the work and carry out risk assessments, prevention and control of potential hazards found in the production process. The method used in this research is Hazard Identification and Risk Assessment & Risk Control (HIRARC). Based on the results of identifying potential hazards at CV Nadha Furniture, it has 5 potential hazards in the high category and 4 potential hazards in the medium category in the production process, including the raw material selection station has 1 potential hazard in the high category, the raw material cutting station has 2 potential hazard categories. high and 1 potential hazard in the medium category, the pattern forming station has 2 potential hazards in the high category and 1 potential hazard in the medium category, and the vinyl installation station and final checking and packaging stations have 2 potential hazards in the medium category. To minimize the level of risk from potential dangers, risk control is carried out which can be done by using gloves, safety helmets, masks and safety shoes as well as providing job training and conducting safety talks before carrying out work..
