Abstract

Permasalahan yang dialami perusahaan yaitu mengenai penentuan jumlah pemesanan bahan baku. Terkadang perusahaan mengalami kesulitan dalam menentukan pembelian bahan baku untuk persediaan di gudang, Dampak yang dapat ditimbulkan yaitu akan menambah beban biaya persediaan bagi perusahaan serta kekurangan bahan baku ketika permintaan produk sedang tinggi. Untuk menyelesaikan permasalahan tersebut maka diperlukan suatu metode EOQ (economic order quantity) yang digunakan untuk mengetahui pembelian yang tepat bagi perusahaan. Tujuan dari penelitian yaitu mengetahui persediaan bahan baku dengan metode EOQ, mengetahui Total Inventory Cost secara keseluruhan dan membuat peramalan permintaan bahan baku untuk tahun berikutnya. Berdasarkan perhitungan dengan metode EOQ maka jumlah pembelian resin yang paling optimal dengan kondisi pemesanan bersyarat yaitu untuk lot order kapasitas truk pengirim resin sebanyak 285,000 kg (19 truk sedang) untuk tahun 2014, dan untuk tahun 2015 sebesar 270,000 kg (18 truk sedang). Total jumlah biaya dengan metode EOQ sebesar Rp. 19.680.000 sedangkan jumlah biaya persediaan dengan metode perusahaan sebesar Rp. 46.488.752 selama tahun 2014-2015. Penghematan yang dapat dilakukan dari total biaya persediaan oleh PT XYZ jika menggunakan metode Economic Order Quantity sebesar 57,66%. Berdasarkan pola data pemesanan yang didapat maka metode peramalan yang sesuai adalah metode regresi linier maka didapat total peramalan resin untuk tahun 2016 sebesar 665,788 kg dengan rata-rata pemakaian perbulan sebesar 55,48233 kg.

Abstract

Material handling becomes an important activity in handling material, first a loading material in the company until unloading material, company X use forklift for material handling in production operation. Overall effectiveness Equipment (OEE) is one method used for measuring the performance of equipment in industries by considering availability, performance, and rate of quality of used equipment. This research purpose was to analyze the performance of forklifts using the OEE method. Based on the results of the study, it is known that during the 6 months of forklift damage varies with the longest breakdown time in June reaching 360 minutes or equivalent to 6 hours. The average value of forklift availability for 6 months period is 97.85% where the operating time is 6000 minutes or equivalent to 20 hours per month. The average value of forklift performance is 97.60% with the number of pianos being transported an average of 1152 units per month. The average value of forklift availability for 6 months is 97.85% where the operating time is 6000 minutes or equivalent to 20 hours per month. The average value of forklift performance is 97.60% with the number of pianos being transported on average per month being 1152 units. The average value of the rate of quality forklift is 98.71% with the number of piano products transported being 1152 units per month, while the number of defective products that fail to be transported only reaches 14.67 or equivalent to 15 products per month. The overall effectiveness method of equipment is obtained at 98.14% where according to Nakajima (1988) the chairman of the Japanese maintenance institute (JIPM) sets the ideal limit of the OEE value index for world-class companies that have implemented TPM, which is 85% and the value of the company's forklift performance is above the standard value. which is set at 98.14%.

Abstract

Mpok Imeh Chips is an Independent small business that produces Balado cassava chips in Jakarta, where cassava chips are packaged using plain plastic so that it has an unattractive impression. This research focuses on developing packaging designs that are following customer desires using the quality function deployment (QFD) method. Based on the results of the study, it is known that the customer's requirement for cassava chip packaging produced by UKM Mpok Imah includes cassava chip packaging that functions to protect the product, a medium packaging size. The form packaging is a standing pouch. Cassava chips packaging is made of polypropylene plastic transparent packaging. There is product information on the packaging. The packaging design is based on the house of quality (HOQ) in QFD and uses polypropylene plastic materials, size (14 x 22) cm, a weight of 250 grams, cassava chips illustration, transparent and a standing pouch packing, description on the label shown on the front view design shows a visualization of the chip's packaging, there is some information about the product including the product name, net weight, address of the producing party and the halal logo. On the back packaging shown, there is information about the composition, storage rules and how used the packaging information expiration date of the packaged product.
