Abstract

Industrialization is an alternative development model needed by the country to spur economic processes. Apart from accelerating the economy, the development of industrialization also has impacts that need to be watched out for, including the presence of a waste industry. One of the companies that manages the waste, namely PT. AJU is also a service company for the procurement and sale of metal waste (metal scrap) in Karawang. The metal scrap studied is canned metal scrap, which is wasteful in the procurement and sales process. So that efforts are made to minimize the waste that occurs. This research uses the Value Stream Mapping method with VALSAT analysis. Based on the research results, the most common types of waste are waiting (28%), inventory (24%), and movement (20%). Then the mapping tools that will be used based on the results of converting the questionnaire scores into the VALSAT matrix are Process Activity Mapping (33%), Supply Chain Response Matrix (20%), and Demand Amplification Mapping (17%). The Value Added Ratio (VAR) before the repair has a value proportion of 3%, while after the repair analysis the VAR value becomes 9%.

Abstract

Penyimpanan produk pupuk urea non subsidi pada gudang bagging PT. Pupuk Kujang Cikampek masih bisa dioptimalkan. Hal ini karena pada penyimpanan beberapa kemasan produk seperti penyimpanan kemasan 5kg yang tidak bisa ditumpuk mengakibatkan pada periode tertentu penyimpanan porudk ini cukup banyak menggunakan space pada gudang. Penyimpanan pada produk 25kg, 50kg dan Jumbo dilakukan secara acak dengan mengisi slot kosong hal ini seringkali terlihat produk tercampur dengan kemasan lain. Maka dilakukan penelitian untuk perbaikan pada tata letak penyimpanan tersebut yang bertujuan menghasilkan jarak perpindahan produk dan ongkos material handling yang minim serta mengoptimalkan kapasitas area penyimpanan produk tersebut. Metode class based storage digunakan dalam menetukan produk-produk yang sering masuk-keluar gudang sehingga memudahkan pembuatan layout usulan. Dibandingkan dengan layout exisiting, layout usulan menggunakan metode tersebut menghasilkan penurunan perpindahan jarak sebesar 56%, 3% pada ongkos material handling yang dikeluarkan serta kenaikan 9% pada kapasitas penyimpanan.

Abstract

Tofu factory “X” is a tofu factory located in Purwakarta Regency, West Java. Purchasing soybeans in large quantities is very risky, because the price of soybeans is very fluctuating. The impact received is when purchasing the price of soybeans purchased when the price is high but when making production at a later date the price of soybeans is falling. This will greatly affect the price of tofu later, because the price sold does not match the market price. The dynamic system model for the availability of soybeans at the “X” tofu factory is in the first scenario the existing model of soybean inventory at the “X” tofu factory. Then the second scenario run is to increase the safety stock by 0.05 or 5%. As for the third scenario used is to use lot size using sack units, in each sack containing 50 kg. Based on the results of the scenarios that have been run, the best scenario that has been simulated in this dynamic system has been chosen. The conditions that occur in this first scenario are models that match the existing. In this first scenario can provide a profit of Rp. 491,898,600.00. Compared to the second scenario of Rp. 467,765,400.00 and the third scenario of Rp. 480,605,800.00.ABSTRAKPabrik tahu “X” merupakan pabrik tahu yang terletak di daerah Kabupaten Purwakarta, Jawa Barat. Pembelian kedelai dalam jumlah banyak sangat beresiko, karena harga dari kacang kedelai ini sangat fluktuaktif. dampak yang diterima adalah ketika melakukan pembelian harga kedelai yang dibeli saat sedang harga tinggi namun ketika melakukan produksi dikemudian hari harga kedelai sedang turun. Hal ini akan sangat berpengaruh terhadap harga tahu nantinya, karena harga dijual tidak sesuai dengan harga dipasar. Model sistem dinamis untuk ketersediaan kacang kedelai pada pabrik tahu “X” adalah pada skenario pertama model eksisting persediaan kacang kedelai di pabrik tahu “X”. Kemudian skenario kedua dijalankan adalah dengan menambah safety stock sebesar 0,05 atau 5%. Sedangkan untuk skenario ketiga digunakan adalah menggunakan lot size menggunakan satuan karung, dalam setiap karung berisikan 50 kg. Berdasarkan hasil skenario yang telah dijalankan, telah terpilih skenario terbaik yang telah disimulasikan pada sistem dinamis ini adalah skenario pertama. Kondisi yang terjadi dalam skenario pertama ini adalah model yang sesuai dengan eksisting. Pada skenario pertama ini dapat memberikan keuntungan sebesar Rp. 491.898.600,00. Dibandingkan dengan skenario kedua sebesar Rp. 467.765.400,00. dan skenario ketiga sebesar Rp. 480.605.800,00.

Abstract

Indonesia has a lot of promising mineral wealth, one of which is copper, but its processing into cathodes is still minimal while domestic demand is not yet sufficient. In accordance with the strategic downstream investment plan for mineral commodities, especially copper, which has been included in the state downstream document, it requires a comprehensive financial feasibility document, especially for PT. X. The analysis in this research uses a reference capacity of 25,000 tons of cathode. This research aims to determine the technical factors in building a copper cathode factory, determine the amount of investment required in the form of CAPEX and OPEX, and determine its financial feasibility. The method used in financial feasibility analysis at PT. This X is Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). Based on the research results, it was found that the total CAPEX (Capital Expenditure) costs that had to be incurred were $ 330,589,628 and the total OPEX (Operational Expenditure) costs that had to be spent was $ 312,257,456 with an NPV value of $ 27,505,439, an IRR value of $ 27,505,439. 15.1%, and PP value for 6 years 10 months. Therefore, the project to build a copper cathode factory at PT. X is worth continuing.
