Abstract

Proyek pemindahan dan penataan selective racking di gudang logistik merupakan aktivitas yang membutuhkan perencanaan waktu yang akurat karena melibatkan rangkaian pekerjaan berurutan yang saling bergantung. Kondisi operasional gudang yang dinamis menuntut adanya metode penjadwalan yang mampu mengidentifikasi aktivitas prioritas sekaligus memperkirakan risiko ketidakpastian durasi. Penelitian ini bertujuan menganalisis penjadwalan proyek pemindahan dan penataan selective racking di gudang PT X menggunakan metode Critical Path Method (CPM) dan Program Evaluation and Review Technique (PERT). Data diperoleh melalui observasi lapangan dan wawancara dengan tim gudang untuk menentukan aktivitas, hubungan ketergantungan, serta estimasi durasi pekerjaan. Hasil analisis CPM menunjukkan bahwa proyek memiliki jalur kritis dengan durasi total 16 hari, yang menjadi waktu minimum penyelesaian proyek. Sementara itu, analisis PERT menghasilkan nilai waktu harapan (TE), varians, dan standar deviasi yang memberikan gambaran probabilitas keterlambatan berdasarkan ketidakpastian durasi aktivitas. Integrasi CPM–PERT memberikan model penjadwalan yang lebih komprehensif dan adaptif, sehingga dapat mendukung pengambilan keputusan terkait prioritas aktivitas, alokasi sumber daya, serta mitigasi risiko keterlambatan. Temuan ini membuktikan bahwa metode CPM–PERT relevan untuk diterapkan pada proyek penataan fasilitas gudang guna meningkatkan efisiensi operasional dan mengurangi potensi downtime selama proses berlangsung.

Abstract

This study develops a minimum-cost distribution optimization model by integrating the Transportation Problem for shipment allocation and the Shortest Path method for minimum-distance routing. Distance, cost per kilometer, demand, and vehicle capacity are quantitatively analyzed using mathematical modeling and then compared with the company’s manual distribution pattern. The results show that total travel distance decreases from 110 km to 80 km and distribution cost drops from IDR 880,000 to IDR 640,000 per trip. The estimated delivery lead time (average speed 40 km/h) is reduced from 2.75 hours to 2.00 hours. A cost sensitivity test (IDR 7,000–10,000 per km) indicates a consistent efficiency of 27.27%, suggesting model robustness to cost fluctuations. This model can support data-driven distribution decisions to improve cost efficiency and operational performance.

Abstract

This study analyzes the influence of constructin value variation on project control effectiveness in Indonesia using a quantity explanatory research design. The data were obtained from the statistics Indonesia (BPS) 2023 report, specifically the dataset on constructin categories. Descriptive analysis reveals highly extreme value variations with several large-scale outliers. Pearson correlation analysis indicates very strong relationship (≥ 0,97) among value categories, suggesting simulatneous escalatin in multi component projects. The findings imply that higher construction values requier more complex control mechanism, including Earned Value Management (EVM), structured risk mitigation, and strist change-order management. This study recommends adopting value-based project control classifications to enhance the effectiveness of cost anda schedule oversight and to support optimal construction project performance.

Abstract

This study aims to identify the most suitable country of origin for Indonesia’s machinery imports by analyzing import data from 2018 to 2024 using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Secondary data obtained from the Central Bureau of Statistics (BPS) include import volume, CIF value, logistics costs, trade stability, and import growth. The analysis process consists of constructing the decision matrix, normalizing the data, assigning criterion weights, determining ideal solutions, and calculating preference values for each alternative country. The results indicate that China is the most optimal source of machinery imports, achieving the highest preference score due to its dominance in volume, economic value, supply consistency, and trade growth. South Korea and the “Others” category follow as strategic alternatives. Overall, the TOPSIS method proves effective in providing objective and measurable support for multi-criteria decision-making related to selecting import partner countries.

Abstract

This study maps development priorities for rail freight in Indonesia based on the spatial distribution of freight volume by major island groups. A descriptive quantitative approach was applied using secondary data on rail freight volume (thousand tons) across five island groups. The analysis includes volume tabulation, share calculations, Java-to-other regions dominance ratios, and a Java versus non-Java aggregate comparison. Results indicate a total of 33.0 million tons, dominated by Java at 18.5 million tons (56.06%), followed by Sumatra 7.2 (21.82%), Kalimantan 4.1 (12.42%), Sulawesi 2.3 (6.97%), and Bali–Nusa Tenggara 0.9 (2.73%). The dominance ratio of Java reaches 20.56 over Bali–Nusa Tenggara and 8.04 over Sulawesi, while non-Java accounts for 43.94% (14.5 million tons). These findings support prioritizing rail freight development outside Java through strengthened logistics nodes and intermodal integration.

Abstract

This study aims to optimize the inventory control of plastic pellet raw materials in the production line of PT. Tiplas by applying mathematical models consisting of Economic Order Quantity (EOQ), Safety Stock, Reorder Point (ROP), and Total Inventory Cost (TIC). One year of observation shows that raw material usage fluctuates significantly, with notable differences in monthly consumption. Such conditions require the company to implement a more structured and measurable inventory control system to ensure smooth production activities and minimize the risk of stockouts. Analysis of monthly consumption data indicates that the average daily demand reaches 768 units, with a standard deviation of 329.24 units, reflecting a high level of demand uncertainty. Using a probabilistic inventory approach, the study determines the optimal order quantity at 9,601 units, safety stock at 1,880 units, and a reorder point at 11,099 units. The results demonstrate that the applied model provides more efficient inventory control recommendations, reduces total inventory costs, and ensures better readiness of raw material availability to support continuous production operations.
