Abstract

PMI Blood Transfusion Unit (UTD PMI) is an agency that provides or a health service agency that organizes blood donation and blood supply. The observations and interviews showed that some existing cases were not carried out immediately and accurately, and there was no distance to align the duration with blood cells. The formation of blood distribution routes only stems from the highest number of requests and the delay in the distribution in several hospitals. Therefore, it is necessary to determine vehicle routes to meet demand due to the limited number of vehicles. The distribution time limit is another obstacle in the distribution process due to delays in delivering blood products from UTD to hospitals or hospital blood banks. In this study, the CCVRPTW solution was determined using a metaheuristic algorithm, namely the Tabu Search algorithm, to minimize blood distribution routes and distances at UTD PMI Pekanbaru. The solution for blood distribution is solved using a programming language through MATLAB software based on the Tabu Search algorithm. Based on the study results, the route 0-1-14-8-18-6-2-17-11-10-4-3-15-9-5-7-16-19-12-13-0 with a distance of 55, 9 KM in 67.1 Minutes. The initial distribution route is 0-1-2-6-5-4-3-7-17-8-13-11-12-14-16-15-18-9-10-19-0 with a distance of 130.7 KM in 156.8 minutes. UTD PMI uses one coolbox with 100 bags of blood capacity, but there is a delay because it only uses one vehicle. The optimized route is divided into two routes: car 1 has a route of 0-1-14-8-18-6-0 with a total distance of 9.2 KM, and car 2 has a route of 0-2-17-11-10-4 -3-15-9-5-7-16-19-12-13-0 with a total distance of 50.6 KM

Abstract

This study evaluates the effectiveness of the blood supply chain and determines potential causes of substandard supply chain performance. Unfulfilled demand for blood at UDD PMI Indragiri Hilir in 2021 reached 970 bags, or 14.1% of all orders. The method used is SCOR (supply chain operation references) and CLD (cause loop diagram). The novelty of this research is applying the SCOR model to holistically measure the blood supply chain's performance and determine the leading causes of low performance. The total value of supply chain performance is 77.78, which is a good category. The results show that Five matrices fall into the low-performance process on the Production attribute (28.24), Capacity Utilization Screening (37.50), Capacity Utilization of Blood Quarantine Storage Cabinets (39.01), Capacity Utilization of Healthy Blood (44.44), and Capacity Utilization Crossmatch (33.3). Based on CLD analysis, potential root causes of the low performance of the supply chain with the CLD model are five low-performance matrices on production attributes influenced by voluntary donors and replacement donors, the number of donors, and blood tapping.

Abstract

Global Putra Swasembada is a company that distributes broiler chickens with a market area in Pekanbaru City. During the distribution process, the vehicle still has remaining capacity, which should be used to load customer orders in other areas. So, the number of tours formed and the number of vehicles used increases, which results in high distribution costs. An effective and efficient distribution method is needed to optimize distribution routes. The research uses the nearest-neighbour method to determine new routes. The results show that the distance of the existing route, which was previously 151.3 km, became 128.8 km, saving 22.5 km. The previous number of vehicles using 4 to 3 optimal vehicles. After calculating the distribution costs, the company paid the cost of Rp. 28,590,800 became Rp. 21,744,000, then there is a reduction in costs of Rp—6,846,800 or 14% every month.

Abstract

PT. DSV Solutions Indonesia is a logistics company facing challenges in efficient warehouse management. One area, Racking Outbound 1, holds the most Stock Keeping Units (SKU). However, materials are placed haphazardly, ignoring item types, leading to damage and difficulty locating materials, which increases search time. This study aims to improve efficiency by using the Class-Based Storage method to group materials and applying an Activity Relation Chart to plan a new layout based on facility proximity. High-frequency materials are placed in accessible areas, while low-frequency ones are stored farther away. This method reduces average search time by up to 57%, allowing operators to access materials faster, with fewer errors and reduced damage.

Abstract

Municipal Solid Waste (MSW) is still an issue in urban areas, including Pekanbaru, one of the most densely populated cities in Riau. The increase in the amount of MSW that is left has an impact on the environment and health. This study aims to provide MSW management policies by analyzing various alternative scenarios, including reduction and treatment. The method used is System Dynamics, which consists of designing a CLD (Causal Loop Diagram) model, then continuing by building an SFD (Stock and Flow Diagram) model composed of 3 alternative scenarios that have three levels each scenario. The simulation period was carried out until 2058. The simulation and model validation results showed that increasing recycling capacity and reducing the use of plastic products can significantly reduce the amount of waste entering the TPA (Final Disposal Site). The best scenario in MSW management is the combination scenario with a 30% reduction in MSW and 72.9% treatment. Waste reduction is carried out through education programs and public awareness, reducing the use of disposable materials and increasing recycling. Waste processing is carried out by constructing modern facilities such as incinerators and compost plants. Implementing this scenario can reduce the burden on landfills and maximize the use of waste as a resource. This research will contribute to developing future sustainable and environmentally friendly waste management strategies. Sampah padat perkotaan atau Municipal Solid Waste (MSW) masih menjadi isu di daerah perkotaan termasuk Pekanbaru sebagai salah satu kota terpadat di Provinsi Riau. Peningkatan jumlah MSW yang dibiarkan berdampak terhadap lingkungan dan kesehatan. Pengelolaan MSW saat ini berupa daur ulang melalui bank MSW dan sanitary landfill, namun hal tersebut belum optimal. Karena timbulan MSW terus meningkat.  Peningkatan jumlah MSW yang dibiarkan berdampak terhadap lingkungan dan kesehatan Penelitian ini bertujuan memberikan altrenatif skenario kebijakan pengelolaan MSW dengan menganalisis berbagai alternatif skenario meliputi pengurangan dan pengolahan untuk Dinas Lingkungan Hidup Kota Pekanbaru. Metode yang digunakan yaitu System Dynamics yang teridiri dari perancangan model CLD (Causal Loop Diagram), kemudian dilanjutkan dengan membangun model SFD (Stock and Flow Diagram). Terdiri dari 3 alternatif skenario yang memiliki 3 tingkat setiap skenarionya. Periode simulasi dilakukan hingga tahun 2058. Hasil simulasi dan validasi model menunjukkan bahwa peningkatan kapasitas daur ulang dan pengurangan penggunaan produk berbahan plastik dapat secara signifikan mengurangi jumlah MSW yang masuk ke TPA (Tempat Pembuangan Akhir). Skenario kombinasi dengan pengurangan MSW sebesar 30% dan pengolahan 72,9% merupakan skenario terbaik dalam pengelolaan MSW. Pengurangan MSW dilakukan melalui program edukasi dan kesadaran masyarakat, pengurangan penggunaan bahan sekali pakai, serta peningkatan daur ulang. Pengolahan MSW dilakukan melalui pembangunan fasilitas pengolahan MSW modern, seperti insinerator dan pabrik kompos Implementasi dari skenario ini dapat mengurangi beban tempat pembuangan akhir dan memaksimalkan pemanfaatan MSW sebagai sumber daya. Penelitian ini memberikan kontribusi penting bagi pengembangan strategi pengelolaan MSW yang lebih berkelanjutan dan ramah lingkungan di masa depan.

Abstract

PT Indotruck Utama is a company that supplies and distributes heavy equipment, including Volvo trucks and construction equipment. One of the main problems this company faces is overstocking in the warehouse, which can lead to additional storage space, increased inventory costs, and the risk of damage to goods. This research aims to optimize inventory management by controlling stock at an ideal level and comparing the current total inventory cost with the proposed price. In this study, the Continuous Review System method is applied by first grouping spare parts using the ABC method. This method categorizes inventory items based on the contribution of fund absorption, where category A items absorb the most significant funds, category B is intermediate, and category C has the most minor fund absorption. A total of 24 spare parts items were grouped into these three categories. Next, inventory requirements were forecasted using historical data to estimate the number of spare parts required in the future. Based on the forecasting results, estimated inventory requirements, optimal ordering point (Q*), reorder point, and safety stock were calculated for each item. The results showed that the current total inventory cost reached Rp 343,368,047.63, while with the implementation of the Continuous Review System, the cost can be reduced to Rp 333,425,336.79. Thus, there is a savings of Rp 9,942,710.84 or about 2.90%.
