Abstract

UDMB is a distributor company of frozen food products in East Kalimantan and North Kalimantan. Time and distance are the biggest obstacles felt by companies in the distribution process. It is because the product must be at a minimum temperature of -18o Celsius so that the product remains in good condition. Meanwhile, the cooling machine on a distribution truck can only maximize working temperature for 6 hours. These travel time and distance problems have occurred more than 12 times a year in out-of-town distribution. Therefore, this research aims to produce an optimal distribution routes with consideration of the fastest time and shortest distance. This problem is solved using the Clarke and Wright Savings Method with the Head and Tail concept and the Cluster First Route Second Method with Sweep Algorithm and Nearest Neighbor. Then, the total distribution time and distance between the results of the two methods are compared. Based on the first results, the total trucks used are 3 units with a total distribution time of 847 minutes and a total distribution distance of 475.8 km. Based on the second results, the total trucks used are 3 units with a total distribution time of 875 minutes and a total distribution distance of 483.8 km. This shows that the Clarke and Wright Savings Method with the Head and Tail concept is the method that produces the most optimal route with the fastest total distribution time and shortest total distribution distance.

Abstract

The selection of transportation fleets plays a crucial role in determining the cost efficiency of logistics operations. This study aims to evaluate the feasibility of investing in company-owned vehicles compared to using third-party rental services on the Bandung–KTSH route operated by the Bandung Branch Office of PT Pos Logistik Indonesia. Using a quantitative approach with a causal associative design, this research applies the Vehicle Operating Cost (VOC) method supported by investment feasibility analysis tools including Cash Flow, Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP). The analysis shows that the average daily operational cost of company-owned vehicles reaches IDR 1.904.479, which is higher than the rental cost of IDR 1.865.385 per day. Additionally, the results show a negative NPV (–IDR 150,550,343), negative IRR (–35.1%), and an unattainable payback period within the 5-year investment horizon. Therefore, it is concluded that using leased vehicles is more cost-efficient than investing in company-owned trucks for this specific route.

Abstract

Transit-Oriented Development (TOD) is an urban concept that reduces dependence on private vehicles and promotes sustainable mobility. As one of Indonesia's metropolitan cities with a railway serving Bandung and its surrounding areas, Bandung can potentially adopt the TOD concept to address transportation and spatial planning issues. Therefore, this study takes three urban railway station areas as research objects, conducts a detailed evaluation of the comprehensive benefits of land use around these stations, and provides relevant recommendations. This study classifies urban railway transportation stations based on land use functions and establishes a three-tier comprehensive benefit evaluation index system across four dimensions: land use, population and building density, public transportation, and design. The research findings indicate that the  Cikudapateuh stations meet five (5) basic TOD criteria, such as adequate pedestrian lane, mixed-use development, operational public transport service, public transport integration, and building coverage ratio (BCR). These findings indicate that TOD-based development in Cikudapateuh should be prioritized over the other two stations because it better meets the TOD criteria. The policy implications of this study recommend the need for synergy between spatial planning, strengthening transit infrastructure, and stakeholder participation to optimize TOD implementation, thereby achieving sustainable mobility in the future.

Abstract

Work accidents are one of the serious problems that have a direct impact on worker safety and company productivity. This study was conducted at PMKS PT. Sisirau located in Aceh Tamiang. This research aims to explore potential sources of danger, evaluate the degree of associated threats, and formulate strategic preventive measures through the structured framework of Hazard Identification, Risk Assessment, and Control Determination (HIRADC) method. The focus of this study was on three work stations, namely loading ramp, boiling (sterilizer station), and tipler. The data used were in the form of work accident reports from January 2021 to February 2025, as well as the results of observations and interviews in the field. The results of the study showed that there were a total of 18 work activities identified as hazardous, consisting of 8 activities at the loading ramp station, 5 activities at the boiling station (sterilizer), and 5 activities at the tipler station. The results of the risk assessment showed that at the loading ramp station there were 5 activities with One activity presented moderate risk; three others showed low-risk potential. At the boiling station (sterilizer) there were 4 activities with a moderate risk and 1 activity with a low risk. Meanwhile, at the tipler station, among the evaluated activities, one was determined to involve a significant risk factor, whereas two others presented comparatively lower levels of risk, and 2 activities with low risk. Recommended risk control includes 7 activities with engineering control, 9 activities with administrative control, and 10 activities with mandatory Application of individual safety gear.

Abstract

The selection of transportation fleets plays a crucial role in determining the cost efficiency of logistics operations. This study aims to evaluate the feasibility of investing in company-owned vehicles compared to using third-party rental services on the Bandung–KTSH route operated by PT X. Using a quantitative approach with a causal associative design, this research applies the Vehicle Operating Cost (VOC) method supported by investment feasibility analysis tools including Cash Flow, Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP). The analysis shows that the average daily operational cost of company-owned vehicles reaches IDR 1.904.479, which is higher than the rental cost of IDR 1.865.385 per day. Additionally, the results show a negative NPV (-IDR 344.739.419), negative IRR (–11%), and an unattainable payback period within the 5-year investment horizon. Therefore, it is concluded that using leased vehicles is more cost-efficient than investing in company-owned trucks for this specific route.
