Abstract

Salah satu kegiatan yang bertujuan untuk mengolah bahan baku menjadi produk jadi sehingga mempunyai nilai tambah disebut kegiatan produksi. UMKM Widi Nugraha adalah salah satu perusahaan yang berjalan di dunia industri tekstil dan berfokus pada produksi kain batik tulis. Seiring berjalannya waktu, permintaan kain batik mulai meningkat dan hal tersebut yang mendorong melonjaknya bahan baku yang harus disediakan. Salah satu upaya perusahaan dalam menangani hal tersebut dengan cara meramalkan data permintaan kain batik dengan menggunakan data masa lalu. Hal tersebut dilakukan dengan tujuan untuk merencanakan penjualan, agar tidak terjadi kekurangan atau berlebihnya jumlah bahan baku yang disediakan. Ramalan permintaan batik selama ini tidak pernah dilakukan dengan metode statistik. Pada penelitian ini akan dilakukan peramalan permintaan batik menggunakan metode peramalan ARIMA Box-Jenkins. Didapatkan total hasil peramalan dalam 12 periode ke depan sebesar 7429 pcs. Hasil ramalan dengan menggunakan metode tersebut diperlukan untuk mengetahui target penjualan yang berkaitan langsung dengan bahan baku yang dibutuhkan. Metode Economic Order Quantity (EOQ) multi-item digunakan untuk menentukan frekuensi pemesanan pengadaan bahan baku yang optimum berdasarkan biaya-biaya yang mempengaruhinya. Hasil analisis EOQ multi-item menunjukkan pemesanan bahan baku yang paling optimum sebanyak 84 kali dalam setahun dengan total biaya paling optimum untuk seluruh bahan baku sebesar Rp. 21.846.616.794.

One of the activities that aim to process raw materials into finished products so that they have added value is production. UMKM Widi Nugraha is one of the companies that operates in the textile industry and focuses on the production of written batik cloth. Over time, the demand for batik cloth began to increase and this prompted an increase in the number of raw materials that must be provided. One of the company's efforts to deal with this is by predicting the demand for batik cloth using past data. This is done to plan sales so that there is no shortage or excess of the number of raw materials provided. Forecasting demand for batik has never been done using statistical methods. In this study, batik demand forecasting will be carried out using the ARIMA Box-Jenkins forecasting method. The total forecasting results in the next 12 periods are 7429 pcs. The forecast results using this method are needed to find out sales targets that are directly related to the raw materials needed. The EOQ method is used to determine the optimal frequency of orders for raw material procurement based on the costs that affect it. The results of the multi-item EOQ analysis show the most optimum ordering of raw materials as much as 84 times a year with the most optimum total cost for all raw materials of Rp. 21.846.616.794.
