ABSTRAK

Dalam dunia usaha dan dunia industri sering dilakukan optimalisasi menyangkut bidang usaha yang ditekuni dengan orientasi untuk mendapatkan hasil yang lebih memadai. Pada penelitian ini tujuan dari diadakannya optimalisasi adalah untuk meminimalkan biaya produksi sehingga perencanaan produksi tersebut harus dilakukan dengan tepat. Perencanaan produksi secara optimal sangat diperlukan dalam mengantisipasi mekanisme pasar dengan segala kemungkinan perubahannya. Adanya fluktuasi permintaan terhadap produk yang ditawarkan harus dicermati dengan baik untuk dapat merebut pangsa pasar. Agar didapatkan gambaran yang jelas mengenai jumlah produksi kain tenun songket yang akan dihasilkan selama dua belas periode mendatang dilakukan peramalan forecasting dengan menggunakan data masa lalu. Metode peramalan yang digunakan terhadap produksi kain tenun songket tersebut adalah model ARIMA Autoregressive Integrated Moving Average dari Box-Jenkins. Hasil pengolahan data setelah melalui tahap identifikasi estimasi dan pemeriksaaan diagnostik menunjukkan adanya white noise. Adapun model peramalan yang didapatkan mengandung faktor musiman yaitu ARIMA 0 0 1 i 2 yang dipilih berdasarkan kriteria pemilihan terbaik dengan membandingkan AIC BIC dan SBC terkecil. Model peramalan ini dinyatakan sebagai Zt a1 07777 at-12. Hasil ramalan beserta ongkos-ongkos denda yang muncul sebagai konsekuensi pengubahan kecepatan produksi jnmlah tenaga kerja penjualan dan kapasitas normal perusahaan diformulasikan ke dalam bentuk program linier linear programming yang mencakup fungsi tujuan dan batasan-batasannya. Penyelesaian dengan metode simpleks memberika 1 hasil berupa kondisi optimum yaitu minimasi dari biaya produksi.


ABSTRACT

In business and industrial fields optimization is often carried out included business establishment in order to obtain a good result. The purpose of this research is to minimize production cost so that the production planning must be done in the right way. Optimization of production planning is needed to anticipate a market mechanism included every change in a market share. A demand fluctuation of the product which is offered must be observed well to obtain a market share. In order to be obtain a description clearly concerning the amount of weaving cloth production will be produced for next 12 periods by forecasting using past data. Forecasting method that is used in weaving cloth production is an ARIMA Autoregressive Integrated Moving AverageBox-Jenkins model. A result of data after passing identification estimation and diagnostic tets stage shows a white noise. The forecasting model that obtained contains a seasonal factor namely ARIMA 0 0 1 12 which is choosed bases on the best criterion by comparing the minimum AIC BIC and SBC. The forecasting model is expressed by Zt at 0.777at_12. The result and the penalty cost which emerges as consequention of production speed changing in amount of workers selling and normal capacity on a company to be formulated into a linear programming which involves an objective function and constrains. The solution using simplex method giving the result of optimum condition namely to minimize from production cost.
