Abstract

Mamminasata (Makassar, Maros, Gowa, Takalar) is one of the urban or metropolitan areas in Eastern Indonesia. Mamminasata as a strategic area with economic interests has an important role in the development of its city and surrounding areas. Meanwhile, the dynamic development of the city causes demands for space needs to increase, especially the need for residential land. The objectives of this study are to 1) know economic development in the Mamminasata district/city in 2001-2021 2) know the development of built-up land in the Mamminasata district/city in 2001-2021 and 3) know the influence and contribution of economic growth to the development of the Mamminasata region. The research location is Makassar City, Maros Regency, Gowa Regency and Takalar Regency. This type of research is descriptive quantitative qualitative. The required data is collected through literature studies in the form of secondary data, namely Gross Regional Domestic Product (GRDP) at constant prices 2010, and google earth images 2001-2021. The analysis used in the research is literature study analysis, qualitative quantitative descriptive, basic statistics, LQ-DLQ, Shift Share, and multiple linear regression analysis. The result of this study is that during 2001-2021 the real income of the Mamminasata Region continued to increase. With the highest growth rate in Gowa Regency. Makassar City only has one leading sector, Maros Regency has two leading sectors, Gowa Regency has three leading sectors, and Takalar Regency has two leading sectors. Only Kabupaten Maros experienced a shift in economic structure from the tertiary sector to the primary sector in 2021 due to a significant economic decline. Spatially, sub-districts that are adjacent or directly adjacent to Makassar City have the most significant built-up land growth with developments following the main road network pattern. Based on the results of multiple linear regression analysis, it shows that there is no significant influence between the independent variables on the dependent variable either jointly or partially individually. Then the t-test was conducted again between tertiary variables and built-up land and showed a significant influence with a contribution of 33% to built-up land.

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.   DOI: https://doi.org/10.51557/mv15pp96

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.   DOI: https://doi.org/10.51557/sqmhpw38

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.   DOI: https://doi.org/10.51557/zer8bm80

Abstract

Workplace accidents remain a critical concern in the palm oil processing industry, which is characterized by complex operations and high-risk activities, particularly in key operational areas such as sterilizers, clarification units, boilers, screw presses, and sand trap tanks. This study aims to identify potential hazards and assess the level of occupational accident risk at PT Perkebunan Nusantara IV Unit Air Batu using a combined approach of Job Safety Analysis (JSA) and Hazard and Operability Study (HAZOP). Data were collected through field observations, questionnaires, and accident reports recorded between 2023 and 2024. The findings indicate that the primary causes of workplace accidents stem from technical equipment failures, unsafe working environments, and non-compliance with standard operating procedures. The highest risk levels were identified at the boiler and sterilizer stations, with risk scores reaching 20–25, categorized as extreme hazard zones. Dominant hazards include exposure to high-temperature steam and hot oil, pressure leakage, musculoskeletal injuries from manual handling, and gas exposure in confined spaces. Recommended corrective actions involve strengthening engineering controls through the installation of interlock systems and automated sensors, developing risk-based standard operating procedures, enforcing appropriate personal protective equipment (PPE) usage, and implementing regular safety training and evaluation. The integration of JSA and HAZOP methods proved effective in providing a comprehensive risk mapping framework and can serve as a strategic reference for enhancing occupational health and safety (OHS) management systems in the palm oil industry   DOI: https://doi.org/10.51557/tmxm7846

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.   DOI: https://doi.org/10.51557/yknegr07

Abstract

Urban traffic congestion in developing cities like Kendari requires rapid and accurate monitoring solutions. This research aims to design and implement an integrated traffic performance analysis system utilizing the YOLOv8 deep learning architecture. The system, named KILALIN, automates vehicle detection, classification, and tracking to calculate road capacity and saturation levels based on the PKJI 2023 standards. A comprehensive dataset of 1,606 annotated images was utilized, partitioned into training (57%), validation (29%), and testing (13.7%) subsets. The developed YOLOv8s model achieved high performance with a mean Average Precision (mAP@0.5) of 0.948, precision of 0.941, and recall of 0.935 across all vehicle classes. Functional validation through black-box testing confirmed the system's ability to process real-time video inputs under various conditions. Comparative results with manual surveys showed a 96% counting accuracy, indicating the system's robustness in quantified traffic flow estimation. Furthermore, the integration of automatic Passenger Car Equivalent (EMP) conversion allows for an immediate determination of the Degree of Saturation (DS) and Level of Service (LoS). These findings indicate that the YOLO-based traffic performance analysis system provides a reliable and efficient framework for urban traffic management, effectively replacing conventional manual survey methods while maintaining high technical standards   DOI: https://doi.org/10.51557/3fxt8a88

Abstract

This research investigates and maps potential risks for Micro, Small, and Medium Enterprises (MSMEs) in Majene Regency, analyzing aspects of Human Resources (HR), capital, production, marketing, and law/legality. MSMEs are crucial to the regional economy , but they often face significant risks that hinder growth. This problem is worsened by a lack of spatial understanding of these vulnerabilities , which makes government interventions and development initiatives less effective. This study aims to spatially model and map MSME risks by integrating multidimensional factor analysis with WebGIS. The methodology involves four stages: (1) acquiring primary and secondary data related to the five risk dimensions; (2) using descriptive statistical and cluster analysis to categorize MSMEs; (3) applying risk factor scoring and weighting analysis to determine potential risk levels ; and (4) developing spatial modeling and GIS for risk visualization. The research results in a classification of MSMEs based on risk levels (high, medium, low), which is presented on a WebGIS platform to allow interactive spatial visualization. The findings are intended to provide a basis for more informed decision-making in the development of MSMEs in Majene Regency   DOI: https://doi.org/10.51557/pgr6ey93

Abstract

The Trans-Sulawesi National Road section Majene-Mamuju (segment 010–009) is a vital land transportation artery supporting the mobility and economy of over 475,000 people. However, its geographical profile, narrow coastal corridors adjacent to steep hills and active fault lines, exposes it to severe multi-hazard threats. This study establishes a fixed infrastructure inventory of 94.7 km of national road and 79 critical bridge nodes to assess susceptibility to earthquakes, tsunamis, coastal abrasion, and landslides. Spatial analysis derived from sub-district data tables reveals that earthquakes are the most pervasive threat, impacting 90.69 km (95.8%) of the road and 65 bridges (82.3% of the inventory). Tsunami susceptibility represents the second most significant hazard, threatening 56.71 km (59.9%) of the network and 51 bridges (64.6%). Coastal abrasion affects 25.20 km (26.6%) of the road and 47 bridges (59.5%). Landslides, while localized, present a high-intensity risk to 5.66 km (6.0%) of the road and 6 bridges (7.6%). The Sendana, Tammeroddo Sendana, and Tubo Sendana sub-districts emerge as the most critical multi-hazard zones, with composite indices ranging from 2.57 to 2.82. While Ulumanda exhibits a high landslide susceptibility ratio (13.0%), Sendana represents the primary operational threat with 1.83 km of exposed road, nearly double the absolute physical impact found in Ulumanda. These findings provide a standardized scientific basis for prioritizing structural mitigation at critical bridge nodes to prevent total network severance during cascading disaster events   DOI: https://doi.org/10.51557/yhjjy774
