Abstract

The adoption of Electric Vehicles (EV) is one of the solutions to reduce emission problems. In Indonesia, the government targets 2.1 million Electric Motorcycles (EM) ownership in 2025. One of the keys to encouraging the EV Indonesian market is vehicle cost analysis, like Total Cost of Ownership (TCO). This study developed a TCO model to compare EM with Conventional Motorcycles (CM) in Indonesia.  Data were collected from surveys and information from stakeholders. The proposed TCO model considered a battery replacement cost, which influenced the resale value of the vehicle. As a result, the TCO of EM had a more economical value than CM of 12% (IDR 3 million) on low mobility, 16% (IDR 4 million) on medium mobility, and 18% (IDR 5.5 million) on high mobility. In addition, several scenarios were also analyzed as a study to consider providing subsidies ownership motorcycles in Indonesia.

Abstract

Taxi services involve the number of taxi and demand. A balance is needed for operated taxi and demand, so that the number of canceled order decreases. This system involves taxi and consumers as agents with various behaviors from their agents, then solved using modeling methods. Agent-based modeling is a feasible method used in this study because it can accommodate the properties and attributes of each agent. From the scenario that has been done, the average number of good fleets to operate is 103 fleets, with the canceled order rate is 1.2% and this model proves that the number of operated taxi is sensitive to the number of requests that exist.

Abstract

Harga Pokok Produksi adalah beban yang dikorbankan dalam kegiatan produksi dari bahan awal mentah menjadi produk akhir yang dapat dijual. Setiap perusahaan memiliki tujuan utama yaitu memperoleh keuntungan sebesar-besarnya. Dalam mencapai tujuan ini perusahaan harus memperhatikan beberapa kondisi, salah satunya perusahaan harus mengetahui penetapan HPP yang sesuai. Hal ini dikarenakan penentuan HPP yang sesuai dan layak berpengaruh penting dalam penjualan produk jadi seperti yang terjadi di CV. Supernova Marketindo Perkasa. Penelitian ini juga bertujuan untuk melakukan perhitungan HPP yang lebih akurat dengan menggunakan metode Time Driven Activity Based Costing karena kriteria harga sangatlah penting dalam keputusan pembelian produk konsumen. TDABC adalah metode yang menggunakan perhitungan dengan dua parameter yaitu waktu yang digunakan dan kapasitas biaya per unit. Metode ini menggunakan times cost driver sehingga dapat memberikan hasil yang efektif dan tidak menyebabkan distorsi biaya yang disebabkan oleh pengakuan/asumsi biaya. Penentuan jenis produk yang tepat juga akan mendukung kinerja perusahaan. Sehingga penerapan metode TDABC dapat meningkatkan kualitas dari pengambilan keputusan yang dilakukan manajemen.

Abstract

As time goes by, there are more problems regarding the quantity and quality of water in Indonesia. One of these problems was found at Sebelas Maret University (UNS), precisely at Sistem Penyediaan Air Minum UNS (SPAM UNS). In serving its customers, SPAM UNS provides water tap and water dispenser facilities. However, there are still many weaknesses in the distribution of water. This is due to the frequent occurrence of pipe leaks and it takes a long time to find the location of the leak. As a result, financial losses experienced are quite large. The purpose of this study is to reduce losses by using the District Meter Area (DMA) concept to determine the area coverage (zoning) and the Analytical Hierarchy Process (AHP) method to determine the location of new reservoirs as a follow up of the zoning system. By implementing the DMA concept and the AHP method, SPAM UNS is able to reduce financial losses. The results obtained are making a new reservoir feasible because the value of the construction is almost the same as the initial loss value experienced by the UNS SPAM distribution network

Abstract

PT. RMC, a company based on make to order which producing ready mixed concrete has not applied acertain ordering method yet. Giving letter of delivery and job-mix to logistics department close to production execution time make logistics department cannot determine requirement of material. Beside that, logistics department works based on work instrument and manual recording so that there are still found many problems which effect on pile up or shortage.It needs a method which can provide the decision about material ordering time and quantity so that result minimum total inventory cost. The method is developed as Decision Support System (DSS). It uses Material Requirement Planning concept (MRP) with daily phased. Determining economic ordering lot size uses static Economic Order Quantity (EOQ) with safety stock (SS). DSS determine Q order if inventory decrease until reach Reorder Point (ROP). With DSS, input and edit data become easier thanbefore.In validation, the proposed method is compared with the current method that result the total inventory cost of proposed method lower than current method. The cost reduction is 10,31 % or Rp. 23.351.790,97439 per month.

Abstract

This paper studies a facility location with single sourcing problem which simultaneously considering opening some new facilities or closing some existing facilities. This problem comes from the inefficiency of the distribution network because of its distribution process growth. One of the mainly caused is each customer zone, which consist of several demand points, served by more than one warehouses. This policy causes high delivery cost and also makes what called marketing conflict. The objectives of this problem solving is determining number, location and distribution coverage of warehouse that could minimizing total logistic cost. Total logistic cost consist of delivery cost from warehouse to customer zone, storage and operation cost at warehouse and transportation cost from plant to warehouse. The best solution is achieved using heuristic approach and optimized using integer linear programming by examining the best configuration network offering the least total logistic cost.
