Abstract

Politeknik Astra is a high vocational education institution that have several laboratories. Welding laboratoy has longest preparation time compare to another laboratories. Gas cylinder changes process in Gas Metal Arc Welding (GMAW) takes 29.2 minutes, which is the longest preparation time so the welding training is hinder by it. Previous condition of  gas instalation is, every GMAW machine equiped with one  gas cylinder,  so if the cylinder is run out of  gas, it have to changes and potentially it could be done more than one machine. The aim of this research is to reduce gas cylinder changes time in welding laboratory using single minute exchange of dies methode (SMED). SMED is one of lean manufacturing metodes that able to identified and reduce or eliminate time waste by separated internal setup and external setup. Using SMED metods, gas cylinder changes activities are identified then divided by internal and external setup. The activities that have no effect to gas flow from cylinder to machine are convert from internal to external setup. For the final, external setup are simplified using 5W2H tools. The solution that reserearcher found using SMED method is to built a centralized gas system with one cylinder as an active gas supply for whole GMAW machine and the other one as  a backup cylinder, in stead of install  gas cylinder on every GMAW machine. The result of this research is setup time for gas cylinder changing process is reduce from 1752 seconds or 29.2 minutes to 877 seconds or 14.6 minute or reduce 50%, furthermore man power alaso reduce from 3 person to 1 person.

Abstract

This research aims to investigate the risk of six big losses and the effectiveness of packing machines at PT Surya Tsabat Mandiri in South Lampung using monthly data on production of bread products from March 2021 to February 2022 used in the research. Research was carried out on packing machine objects using quantitative data or data that can be measured systematically. The Overall Equipment Effectiveness (OEE) method is applied to measure the total performance of equipment as a whole according to what must be done and to assess the dominant factors of the Six Big Losses which are dominantly used by the fishbone diagram approach. The research results show that the average OEE value of packing machines is 78.17% and is still below world standards (≥85%). Apart from that, evidence was found that the most dominant six big losses factors were idling and minor stoppage losses with a value of 16.85% and reduced speed losses with a value of 7.85%. Based on the fishbone diagram, the aspects that cause speed losses on packing machines are humans (lack of operator knowledge, lack of workers guarding bread baskets), machines (repair of damaged machines, unstable center and end seal temperatures), environment (unstable production room temperature) and method (non-periodic machine maintenance). The recommendation given to reduce these two losses is to use the TPM pillars, namely education and training, autonomous maintenance and planned maintenance.

Abstract

Seblak is a food that has seen an increase in demand in recent years, and is a promising culinary business that can be run with a small capital. UD. XYZ is a seblak business that started selling seblak in early 2022 in West Aceh and wants to maximize the profits from its seblak sales. One method that can do this is Linear Programming, which can determine decision-making that can group limited materials or resources to achieve an optimal or best solution. From UD. XYZ's weekly sales data, it can be transformed into a mathematical model that helps to find the maximum function of the profit from seblak sales. The linear programming calculation process in this study uses the Lingo 18.0 software to solve linear programming problems, which will be continued with the linear graph visualization of the objective function with the MATLAB software. The results of the study show that the maximum profit that will be obtained by UD. XYZ in one week is Rp. 420,000/week, this profit is already categorized as net profit that can be used for the development of UD. XYZ's seblak business. Of the three variables X1 (seblak noodles and crackers), X2 (seblak eggs), and X3 (seblak chicken/feet), variables X1 and X2 have the potential to increase maximum profit if increased.

Abstract

So far, small and medium enterprises (MSMEs) have shown a contribution of 61.7% to GDP, or IDR 8,573.89 trillion. Apart from that, MSMEs can absorb around 97% of the national workforce. However, in reality, MSMEs face many problems, one of the most common being a lack of business capital. One of the factors causing the slow growth of MSMEs in Indonesia is development policies that are not on target. This is especially true for this research in West Aceh District. Each MSME is unique, making it difficult for banking institutions to establish consistent financing policies. This research aims to map the characteristics of MSMEs in the form of groups to make it easier to determine policy-making patterns. The Hierarchical Data Mining Clustering Method is considered appropriate because it has a much lower bias than K-means. Apart from that, this method can reduce data complexity. According to the results of data distribution for MSMEs in the fisheries sector using Matlab 2016b software, there are 6 clusters, and the results of data distribution for MSMEs in the trade sector using Matlab 2016b software show 7 clusters. Each cluster has main parameters that make MSMEs superior, such as length of business, capital ownership, sales projections, and average sales. For the last parameter.

Abstract

PT. Karunia Selaras Abadi is a flexible packaging converting company. This company produces various types of plastic packaging for snacks, powdered drinks, soap, etc. This company produces more than 10,000 rolls and 1,000,000 bags every week so that the printing cylinders at PT. The Gift of Eternal Harmony reaches more than 3,000 items. The cylinder washing process is stressful for workers, thereby triggering fatigue which results in decreased productivity. Workers handle materials incorrectly using Manual Material Handling, causing workers to experience pain in their body parts. Workers' muscles receive continuous static loads over a long period of time, potentially resulting in musculoskeletal disorders. Thus, workers are asked to fill out the CMDQ questionnaire which aims to determine the level of ergonomic risk. Based on the CMDQ questionnaire, the body parts that workers often experience pain are the knee (left), shoulder (right) and lower back. Followed by an assessment of work posture using the OWAS method including the back, arms, legs and load, then completed with an assessment of work posture using the REBA method. There are 2 activities that have a high level of risk according to the OWAS method, washing cylinders using category 3 solvent, checking cylinders, category 3. For research on the REBA method, washing cylinders using solvents with a score of 8, checking cylinders with a score of 10, these results show that all activities require an improvement process.

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

The current initiative on SMEs development suggest that effective partnership programs play a pivotal role in enhancing SME competitiveness. However, current research in the area of partnership programs, specifically their impact on SMEs performance, remains limited. Therefore, partnerships need to be examined with an emphasis on moderator variables to assess their impact on various aspects. This research presents an objective to determine a partnership program impact on SME performance. To fully understand the dynamic of the study, this research propose a Partnership Program model consists of three exogenous variables: Entrepreneurial Competence (KK), Partnership Program (PK), and Digital Competence (KD), and one endogenous variable: SME Business Performance. To analyse the data in the research, this research employs the Partial Least Square (PLS) analysis method. The PLS model is utilized to examine and determine the extent of influence among variables. The research population comprises 88 coffee-based SMEs participating in a partnership program in Bener Meriah Regency. The result of this research indicates that the significance test for the relationships within the Structural Model reveals strong statistical significance among various research parameters. Notably, the impact of digital competence (KD) on SMEs performance (KB) demonstrates the most robust relationship, with a substantial Std Beta value of 0.902. This pattern is consistent with the perspective of partnership programs (PK), where it exhibits significant effects on SMEs performance (KB) (0.429), digital competences (KD) (0.294), and entrepreneurial competences (KK) (0.451).
