Penelitian ini dilakukan pada gudang bahan kemas pada PT.X. Permasalahan yang terjadi pada gudang bahan kemas ini terjadi pada saat melakukan penyimpanan produk, operator akan langsung menyimpan produk pada rak yang kosong. Selain itu penempatan produk yang terdapat dalam gudang ini ditempatkan tidak berdekatan dengan produk sejenisnya. Berdasarkan hal tersebut penelitian ini bertujuan untuk merancang tata letak gudang agar mempemudah operator dalam proses penerimaan, penyimpanan dan pengiriman produk di gudang, sehingga dapat meminimumkan jarak tempuh pemindahan produk. Pada penelitian pendekatan yang digunakan adalah metode Class Based Storage. Berdasarkan hasil dan pembahasan dip...

It aids enterprises on how to minimize the total of production costs by reducing the inventory cost. However, the three main parameters in EPQ model, demand, set up cost, and holding cost, are not sufficient enough to solve current inventory issues. When an enterprise has two types of demand, continuous and discrete demands, the basic EPQ model would be no longer useful. Continuous demand comes from customers who want their demand to be fulfilled every time per unit time, while the fulfilment of discrete demand is at a fixed interval of time. Literature review is conducted to observe other formulations of EPQ model. As literature dealing with this problem cannot be found, this study aims to develop an EPQ model considering the two types of demand simultaneously. Therefore, this research proposes a modified EPQ model considering both continuous and discrete demands under...

Proporsi terbesar bahan baku yang diolah berasal dari kebun inti. Sistem persediaan push system seperti ini mengakibatkan perusahaan melakukan produksi terus menerus, sehingga keandalan mesin menjadi sangat penting. Replenishment persediaan material & spare part yang mendukung aktivitas penggunaan mesin, tidak dapat dilakukan secara mendadak ketika dibutuhkan. Ketersediaan yang terlalu tinggi dapat mengakibatkan overstock yang berakitbat tingginya biaya simpan serta risiko penyimpanan produk bagi perusahaan. Penelitian ini bertujuan menghitung jumlah minimal dan jumlah maksimal persediaan material dan sapre part yang memiliki tingkat stockout tertinggi pada gudang material di PT XYZ. Perhitungan dilakukan dengan metode Minimum-Maximum Stock Level (MMSL) pada material oxygen isi ulang, oli turalik, baut mur ¾ x 3” baja, baut mur ¾ x 4” baja , kawat las RB 26 dia. 3,2 mm, dan kawat las LB 52 U dia. 3,2 mm....

Bulk cooking oil controls 75 percent of the production market share in Indonesia and about 77.5 percent of households in Indonesia use bulk cooking oil because the price is cheaper than packaged cooking oil. Demand for olein in the future is predicted to be continued to increase, so it is necessary to estimate future sales so that production activities become more effective and efficient. The method used in this study is the double moving average (DMA), which is one of the forecasting methods with data that has a trend. The calculation will be done by comparing the result of 3 moving, 4 moving and 5 moving. Forecasting error is calculated using mean absolute percentage error (MAPE). The calculation results show that the average MAPE from DMA with 5 moving has the smallest value. To verify these results, an analysis of the processed data was carried out, namely looking for data with the furthest distance from ...

Similarly, investment in processing coconut yields into virgin coconut oil (VCO) provides a promising future by applying agriculture 4.0. This paper presents decision support system which provides investment decision toward new VCO agroindustries. The contribution lies in the improvement management system with observed several aspects before the investment is carried out. The approach combines nature dataset and economics analysis. The methods cover spatial analysis, location quotient, capacity production planning, and financial analysis. The result presents four study case of VCO investment in Pariaman districts in West Sumatera Indonesia, which decision about feasibility investment of VCO agroindustry in selected potential area. This DSS application permits the investor to be facilitated with an accurate and fast decision. Although, the DSS requires futures improvement with a fully online application without an overlay process.

Cabai merah besar (Capsicum annum l.) salah satu produk pertanian hortikultura yang banyak diusahakan oleh petani. Sumatera Barat dengan konstribusinya sebesar 5,83% atau sebesar 58.064 ton per tahun menghasilkan sentra produksi cabai yang berasal dari beberapa daerah akan tetapi yang menghasilkan produksi cabai terbesar berada di Kabupaten Solok yaitu 19.325 ton. Namun ironisnya harga cabai sering mengalami fluktuasi yang tidak teratur. Suatu ketika cabai bisa mencapai harga yang sangat mahal, lalu harga akan sangat jatuh ketika panen melimpah. Beberapa petani bahkan sampai membuang cabai-cabai hasil panen yang masih bagus karena harga jual cabai pada panen raya sangat rendah. Untuk membantu para petani dalam mengatasi fluktuasi harga tersebut, perlu dilakukan upaya-upaya pemanfaatan cabai merah menjadi aneka produk melalui pengolahan cabai merah dalam bentuk bubuk dengan rasa original. Metode pelaksanaan yang dilakukan berupa penyuluhan kepada masyarakat tentang nilai ka...

The development of rural industries will create new jobs so that the community economy will increase. Coconut has a lot of derivative products, one of which is cocofiber produced from coconut coir. Coconut coir itself is one of the remaining coconut products that can be processed so as to increase the value of the product. Location determination and financial analysis can help potential investors to make cocofiber agroindustry development decisions. The method used to determine the location of the factory is gravity location model (GLM), using data on the coordinate point of coconut IKM in Kab. Padang Pariaman. For financial analysis is calculated using Net Present Value (NPV) and Internal Rate of Return (IRR). Both of these methods are expected to illustrate whether the development plan ...
