In recent years, the use of small-scale liquefied natural gas (LNG) has grown alongside demand from industrial users of natural gas. Small-scale LNG is an alternative to the supply of natural gas to remote areas with a cost-effectiveness challenge. To address this challenge, five mobile power plants located in remote areas with limited depth of water level in western Indonesia are used here as a case study. The objective of this paper is to optimize LNG distribution using small-scale LNG carriers and carry out an economic analysis in this region. The capacitated vehicle routing problem model was used to optimize the maritime routing of a small-scale LNG supply chain. The maximization of the volume cargo with a given LNG vessel capacity set as the objective function was therefore provided with the optimum inventory routing and economic analysis of the transport of LNG. Cluster 1 serves three power plants with a total demand of 966 m 3 /day and a distance is 913 Nautical Miles, while cluster 2 serves two power plants with a total demand of 690 m 3 /day and distance of 1,483 Nautical Miles. Economic analysis of the two clusters shows that there is a minimum difference in the margin rate needed to make it worth the investment, which is 3 USD/MMBTU for cluster 1 and 4 USD/MMBTU for cluster 2. Thus, this paper concludes that the cost of LNG transportation depends on the amount of cargo demand and shipping distances.
Arranging an optimal distribution system is a challenging step in every company who runs logistics activities because it is one of the crucial factors to achieve high customers’ satisfaction level. This problem becomes more complex during the high or special seasons such as Christmas, new year, etc. In Indonesia, high season for logistics usually during the Eid season. During that special season, the demand increases while the resource decreases due to long national holiday. Failed to find an optimal distribution system might lead to a huge loss for the company. Therefore, to overcome this problem, logistics company should optimize the distribution system including optimizing the route and vehicles utilization. This paper aims to help a logistics company based in Bali, Indonesia, to find an optimal distribution route during the Eid Season. This company find difficulty to fulfil the customer demands especially during the Eid Season. To find an optimal route for the company, this paper applies Saving Matrix and Nearest Insert methods. These two algorithms are chosen because both of them have a simple procedure. Thus, it can save the computational time. Besides, a simple procedure will help the company to reuse the proposed methods for the next application. Data collection and observation in this paper were carried out during one week of Eid season in 2019. The computational results show that the optimal route is able to deliver all items before the due date with total distribution time 7 hours 16 minutes. Compare with the existing route, the proposed route reduces the total cost by 30%.
Pelabuhan Sorong memegang peranan penting dalam kegiatan ekspor dan impor peti kemas khususnya di wilayah provinsi Papua Barat. Berdasarkan observasi di lapangan, kegiatan operasional di terminal peti kemas Pelabuhan Sorong belum berjalan dengan efisien karena tata letak lapangan penumpukannya belum dirancang dengan teratur. Oleh karena itu, penelitian ini bertujuan untuk memberikan usulan tata letak lapangan penumpukan untuk Pelabuhan Sorong. Usulan tata letak dirancang berdasarkan hubungan antara aktivitas-aktivitas pergerakan peti kemas di terminal dan ramalan permintaan peti kemas. Penelitian ini menerapkan metode peramalan untuk meramalkan jumlah peti kemas impor dan ekspor serta mengidentifikasi jumlah kapasitas yang dibutuhkan lapangan penumpukan. Hasil rancangan dari usulan tata letak dievaluasi utilitasnya menggunakan rumus Yard Occupancy Ratio (YOR). Berdasarkan perhitungan, usulan rancangan tata letak lapangan penumpukan dapat mengakomodir jumlah permintaan peti kemas Pelabuhan Sorong dengan nilai YOR yang mendekati standar kinerja pelabuhan yaitu 71,03% pada tahun 2025.
A dry port is established as an inland extension of a port. Tanjung Intan Port, which is located in Cilacap and within the range of tsunami risk zones, has no dry port to accommodate its distant customers. This research proposes a dry port location selection for Tanjung Intan Port with the following main criteria: safer from tsunami risks and achieve maximal demand coverage. By applying AHP (Analytical Hierarchy Process), the location candidates were ranked and further selected using MCLP (Maximum Coverage Location Problem) to choose the best candidate. The study result selects Maos railway station as the most attractive dry port location. The feasibility study result shows that the location has: (1) a lower risk of tsunami impact, (2) potential for the port’s market expansion, (3) less pollution potential, (4) adequate railway tracks, (5) large area, (6) good location away from densely populated areas and, (7) easy access for trucks.
Krupuk Mlarat merupakan salah satu makanan khas yang berasal dari Kota Cirebon. Saat ini sebagian besar UMKM yang memproduksi Krupuk Mlarat masih menggunakan cara tradisional dan sangat sederhana, sehingg tidak pelaku usahanya tidak berkembang sesuai dengan harapan. Oleh akrena itu, dalam pengabdian kepada masyarakat ini dilakukan pendampingan terhadap UMKM Krupuk Mlarat di Desa Setu Kulon Cirebon. Metode yang dilakukan adalah pemetaan potensi, perbaikan proses produksi, perbaikan kualitas pengemasan dan pelatihan kewirausahaan dan pembukuan sederhana. Hasil kegiatan berupa pemetaan profil UMKM Krupuk Mlarat, memberikan usulan perbaikan tata letak proses produksi, memberikan usulan kemasan Krupuk Mlarat dan juga melaksanakan pelatihan kewirausahaan dan pembukuan sederhana. Terlaksananya kegiatan ini diharapkan dapat memberikan semangat dan motivasi kepada pengusaha UMKM Krupuk Mlarat dalam mengelola usahanya
