Abstract

Article history : The rapid growth of the tourism industry, especially in Indonesia, has positively impacted various other sectors. This growth has indirectly spurred the development of supporting businesses, predominantly small and medium-sized enterprises (SMEs), such as tourist transportation rentals. Rising tourist demands for transportation necessitate that entrepreneurs in this industry adapt quickly, including investing in the latest vehicle units. However, investing in new vehicles is challenging, especially for small-scale rental owners. They must carefully calculate their investment, considering various potential risks. Therefore, this study recommends alternatives for new vehicle investments in tourist transportation rentals based on BWM and SAW. A case study on small-scale rental businesses in Yogyakarta has been selected. The results indicate that five criteria must be considered for new vehicle investments in tourist rentals: vehicle type (C1), fuel consumption (C2), engine specifications (C3), rental price (C4), product lifetime (C5), and price (C6). The optimal weights of these criteria are determined using BWM to rank five investment alternatives: KIZ, HIC, AVZ, BRI, and SGR. The findings suggest KIZ as the potential top investment priority, followed by AVZ, BRI, SGR, and HIC.

Abstract

The construction industry, particularly road construction, supports economic growth and enhances community mobility. One of the primary challenges is ensuring that the quality of hot mix asphalt (HMA), a critical component in road construction, aligns with customer needs and expectations. This study aims to evaluate customer satisfaction with HMA products produced by PT. SKS in Yogyakarta. The Importance-Performance Analysis (IPA) approach was employed to identify gaps between the product's actual performance and the importance level expected by customers. Data were collected from 25 respondents using a Likert-scale questionnaire covering 20 service attributes, including guest facilities, product services, and quality control. The data were analyzed using a Cartesian diagram to map attributes into four priority quadrants. The findings revealed that the average performance score (3.93) was slightly lower than the average importance score (4.13), indicating gaps in several attributes. Attributes such as the availability of project safety shoes (Q8) and accessibility (Q9) fell into Quadrant A, requiring immediate improvement. Meanwhile, attributes like product quality (Q14) and delivery reliability (Q12) in Quadrant B must be maintained. This study concludes that enhancing the priority attributes in Quadrant A can significantly improve customer satisfaction. The findings provide strategic recommendations for the company to enhance efficiency, improve product quality, and meet customer expectations.

Abstract

A robust production system needs to be implemented across all business scales, including small-scale enterprises managed by community groups. This forms the foundation for the development of more competitive businesses. As reported in this paper, a community service program was elaborated to design a production system for a stagen weaving business group located in Moyudan, Sleman, Indonesia. To implement this production system, there are five main stages: situational analysis, production system design, workshop, implementation, and monitoring and evaluation. A pilot project was tested on four weavers with distinct characteristics. The results indicate that each of the four weavers produced different stagen patterns with significant revenue gains for weaver 1 and weaver 2 amounting to more than IDR 500.000 (360.24 meters and 237.43 meters, respectively). This program successfully achieved specific targets in line with the scope.

Abstract

This paper studies on proposed inventory policy at a well-known pharmacy in Riau Province, Indonesia. Pharmacy X often experiences stockouts, especially during the critical period of the COVID-19 pandemic. These stockouts lead to lost sales. The Q and P inventory models are used to determine the optimal order quantity and order period using several simulation scenarios. Storage capacity and the ability of suppliers to supply drugs are constraints in this study. However, only 7 SKUs that often run out will be examined. The purpose of this paper is to minimize the shortage level of the SKUs using a parameter of shortage costs. After simulation, it was proven there was a decrease in the shortage costs in each SKU compared to the actual state. The reduction reached 23% - 74%.

Abstract

Currently, it is obvious that occupational health and safety culture in companies is on the rise including a focus on workers’ working postures. However, the implementation of these initiatives tends to be notably deficient, particularly in small and medium-sized enterprises (SMEs). This research aims to introduce a framework for evaluating workers’ working postures taking into account ergonomic factors and other influential factors. In this study, the developed evaluation model was applied to an SME producing kitchenware situated in Indonesia using rapid upper limb assessment (RULA), and the method was combined with multi criteria decision-making (MCDM). There were five criteria identified, namely RULA score (C1), the activity’s level of importance (C2), duration (C3), work station environmental condition (C4), and supportive equipment (C5). These five criteria were considered to evaluate five working postures on the production floor. The result indicated that based on the RULA score, five postures were categorized as high risk. Besides, by considering the criteria, working posture in assembly activity (posture 3) has the highest risk level which requires immediate corrective action. This research is applicable as the evaluation of work posture is assessed by considering ergonomic factors and the level of importance for each activity.

Abstract

The LPG gas base carries gas to homes and shops using a two-wheeled motorcycle fitted with an iron basket to have gas. A design needs to be designed to make it easier to transport gas. This study aims to determine the weight of criteria that are important for consideration of design design for a gas conveyor. Quality Function Deployment (QFD) is a structured methodology used in product planning and development to obtain consumer needs and wishes specifications. Multi-Criteria Decision Making (MCDM) is a method for making alternative decisions based on specific criteria. The result of this study is the weighting of measures necessary for consideration of design for a gas conveyor of the most crucial sequence, namely: type of material used, weight, strength, size and dimensions, flexibility, maximum capacity, durability, comfort, attractive graphic design, efficiency (gallons, gas 3kg, 5.5kg, 12kg), and thickness
