Abstract

Competition in industrial sector does not only apply to garment and electronic subsectors but also to food & beverage subsectors. Accordingly Mujur Jaya—a medium enterprise operating in food & beverage subsector—is required to maintain its existence, growth, and competitiveness. This can be accomplished through production decision which leads to production efficiency and product quality improvement. The objective of this study is to analyze time efficiency and cost of production processes within the firm. Network analysis was applied. Primary data regarding chronological order, time, and costs of production processes were collected and directly measured at the location of the firm. Critical Path Methods, in particular methods of Earliest Start Time & Earliest Finish and Latest Start Time & Latest Finish Time were used to analyze data. Results of the study indicated that production process cost can be reduced up to IDR1870 per production cycle by cutting production time by approximately 2 minutes. In the long term, this improvement (i.e., time and cost of production process) would be of beneficials for the firm.Key words: network analysis; critical path methods; time of production process; cost of production process.

Abstract

Persaingan di sektor industri tidak terbatas pada subsektor pakaian dan elektronik tetapi juga subsektor pangan atau bahan makanan. Oleh karenanya Perusahaan Mujur Jaya dituntut untuk menjaga eksistensi, pertumbuhan, dan daya saingnya secara berkelanjutan. Salah satu caranya adalah melalui pembuatan putusan proses produksi yang bermuara pada peningkatan efisiensi dan kemampuan untuk menghasilkan produk yang bermutu. Penelitian ini dilakukan dengan tujuan untuk mengukur efisiensi waktu dan biaya proses produksi perusahaan yang menjadi objek penelitian. Analisis jaringan (Network Analisys) digunakan dalam penelitian ini. Data berupa urutan proses produksi, waktu, dan biaya yang diperlukan oleh setiap urutan diperoleh melalai pengamatan langsung di lokasi penelitian. Metode jalur kritis (Critical Path Method), khususnya metode algoritma Earliest Start Time & Earliest Finish and Latest Start Time & Latest Finish Time digunakan untuk menganalisis data. Hasil penelitian menunjukkan bahwa dengan memperpendek waktu produksi selama 2 menit, perusahaan dapat menghemat biaya sebesar Rp1.870 per produksi atau Rp1.570.800,- dalam satu tahun produksi. Meskipun relatif kecil, penghematan tersebut untuk jangka panjang akan memberikan keuntungan yang cukup signifikan bagi perusahaan.
