Abstract

UD XZ merupakan industri rumahan yang berlokasi di Kabupaten Gresik. Perusahaan ini memproduksi alat musik tradisional. Bahan baku utama yang dibutuhkan untuk proses produksi rebana adalah kayu dan kulit kambing.Sistem perusahaan dalam mengolah bahan baku yaitu melakukan pembelian secara terus menurus tidak memperkiraan bahan baku yang dibutuhkan, sehingga mengakibatkan kualitas bahan baku kayu menurun karena kayu mudah dibentuk sehingga menimbulkan banyak biaya penyimpanan. Hasil penelitian terhadap metode peramalan yang dipilih adalah Wighted Moving Average untuk uji normalitas data berdistribusi normal. Perhitungan Economic Order Quantity Probabilistik menghasilkan total biaya persediaan sebesar Rp. 108.803.275 dan Rp. 102.260.550. Sedangkan total biaya persediaan perusahaan adalah Rp. 129.580.000 dan 113.220. 000 sehingga perusahaan dapat melakukan penghematan sebesar 16% untuk bahan baku kayu dan 9,6% serta untuk perhitungan harga pokok produksi rebana tanpa motif sebesar Rp. 106.536 dengan harga jual Rp. 140.000 per unit, sedangkan rebana berukir Rp. 121.536 per unit dengan harga jual Rp. 160.000 per unit.

Abstract

Tujuan dari analisis pengendalian persediaan adalah untuk mengoptimalkan jumlah persediaan oli mesin mobil di toko Fifa Motor dengan menggunakan metode Economic Order Quantity (EOQ). Hal ini dilakukan karena toko Fifa Motor mengalami masalah dalam memperkirakan permintaan, yang mengakibatkan pembelian yang berlebihan atau kekurangan stok. Metode EOQ digunakan untuk menentukan jumlah persediaan yang tepat, dengan mempertimbangkan biaya-biaya yang relevan seperti biaya pembelian, biaya pemesanan, dan biaya penyimpanan. Dalam analisis ini, juga dilakukan perhitungan frekuensi pemesanan, safety stock, dan re-order point untuk memastikan pengendalian persediaan yang efektif dan efisien. Dengan menggunakan metode EOQ, diharapkan biaya yang dikeluarkan oleh toko Fifa Motor dapat diminimalkan ketika melakukan pemesanan stok barang. Hasil penelitian menunjukkan pemesanan ekonomis oli mesin dengan jumlah pembelian sebesar 672 galon untuk setiap pesanan, untuk persediaan pengaman (Safety Stock) sebanyak 160-239 galon per tahun dan 13-20 galon per bulan untuk setiap jenis oli, dan titik pemesanan kembali (Re Order Point) ketika stok oli mesin mobil mencapai 5-7 galon untuk setiap jenis oli.

Abstract

Home Industry Achmad Rochman is a company engaged in the manufacture of skullcaps, in the production of skullcaps there are 3 types namely AC skullcaps, Standard skullcaps and stacking skullcaps, in the production process the company does not yet have a standard time as a reference for making skullcap products. The production process at Achmad Rochman is only based on targets so that workers must complete according to the company's targets because they do not yet have a standard time reference for each skullcap and an order system within the company, namely Make to order and requests are always changing. The results of calculating the standard time using the working time measurement method with a stop clock yield a standard skull cap of 1099.33 seconds, an AC skullcap has a standard time of 1189.13 seconds and for stacking skullcaps a standard time of 1129.29 seconds. Optimizing the workforce using the Work load Analysis (WLA) method and producing a standard skull cap requires 20 workers, corporate stacking requires an optimal workforce of 20 workers and AC cap to meet demand requires an optimal workforce of 30 workers plus 2 workers in sewing operations sum Keyword: Cycle Time, Work Load Analysis, Work Sampling.

Abstract

PT Adiprima Suraprinta is a subsidiary of Jawa Pos Group which is located in Sumengko Village, Wringinanom, Gresik. PT. Adiprima Suraprinta was founded in 1997, this factory is one of the industrial companies in Indonesia that produces paper. With paper industry competition being very tight, PT Adiprima Suraprinta needs to innovate and pay attention to the quality of its products to maintain stability in quality in order to become the leading paper company in Indonesia. Based on the results of the research and discussion analysis that has been described, it is known that the production of News Print Paper type newsprint in the 2022 period is 52174 Tons with defective conditions that occur in production of 14633 Tons of copies. The average defect in each production in a one-month period is 30%. in several production times there were defects that exceeded the target of the number of production. The analysis method used is check sheet, control chart, pareto and fishbone. This is based on observations made where damage to newsprint paper occurs during the production process using the company's Paper Mill machine where each machine is run by several operators. Therefore, efforts to overcome the occurrence of defects caused by these factors can be carried out by providing training to workers, creating a new work appraisal system with the aim of motivating workers' performance to be better. Checking the readiness of the machine before and after use so that it is in accordance with operational standards and Immediately replace damaged engine components so that they do not hinder the production process

Abstract

In 2022 the government in Blitar Regency reduces the amount of subsidized chemical fertilizers again, this has been done for several years by the central government. The main goal is to replace chemical fertilizers with organic fertilizers. However, the lack of government assistance for the use of organic fertilizers causes farmers to suffer losses due to crop failure or crop yields that are far from expectations. This causes the cost of rice production to increase while the quality and weight decrease. The farmer movement in Papungan Village has created a nutritional formula that can replace chemical fertilizers without reducing crop quality and also requires a large amount of money to make these nutrients. This study uses the full costing method which calculates all the cost elements incurred by farmers who use chemical fertilizers and those who use nutrients. Then see if there is an average growth equation if the two are compared using the T-Test method. The results obtained from the calculation of the cost of production can be used as a reference for farmers to switch to nutrition and not rely on chemical fertilizers whose prices have skyrocketed
