Abstract

Sebagai perusahaan yang bergerak di sektor industri tekstil, PT. XYZ yang berlokasi di Kabupaten Sukoharjo menggunakan thermal oil boiler dengan bahan bakar batubara untuk mengoperasikan mesin-mesin di bagian produksi. Sebelum melakukan pembakaran batubara ke tungku boiler, operator boiler terlebih dahulu melakukan proses pemecahan batubara secara manual menggunakan palu dengan tujuan untuk memaksimalkan pembakaran batubara secara merata guna menjaga temperatur oil tetap stabil agar proses produksi tidak terganggu. Dalam kondisi tersebut, proses pemecahan batubara membutukan usaha manusia yang tidak sedikit dan lama untuk melakukannya, sehingga perusahaan mengeluarkan biaya operasional produksi yang tidak sedikit pula. Penelitian ini bertujuan untuk menganalisis kelayakan usulan investasi rancangan mesin pemecah batubara kapasitas kurang lebih 10 ton per jam sesuai kebutuhan produksi guna menggantikan proses pemecahan batubara secara manual. Penelitian ini menggunakan metode evaluasi investasi Net Present value, Annual Equivalent, Benefit Cost Ratio, dan Payback Period. Hasil perhitungan analisis kelayakan investasi dengan umur investasi 8 tahun menghasilkan nilai NPV Rp 419.200.488,8492 lebih besar dari 0, nilai AE Rp 66.171.955,16 lebih besar samadengan 0, nilai BCR 1,851 lebih besar samadengan 1, dan PBP sebesar 0,2007 tahun lebih kecil samadengan 8 tahun (umur investasi). Berdasarkan hasil perhitungan tersebut maka usulan investasi mesin pemecah batubara dapat dikategorikan layak diterapkan untuk menggantikan proses pemecahan batubara secara manual karena memenuhi ukuran atau kriteria investasi

Abstract

Furniture is one of the main needs of every home. Furniture designs that are currently trending are minimalist designs, namely designs that prioritize the main function and comfort of the user. One type of furniture that many consumers need is a study table. There are many study table designs available, but there are consumer needs that have not been met by the available product designs. The aim of this research is to design a minimalist wall study table. A study table attached to the wall will be functional and save space. This is in accordance with the minimalist concept applied. The method used is Quality Function Deployment (QFD). This QFD method involves consumers from the early design stages so that the design results will be in accordance with what consumers need. Consumer needs are then linked to the corresponding technical characteristics. The technical characteristics of a study table with the highest value are the main priority in design. The survey results using the QFD method show that the technical characteristics with the highest scores are (a) selection of durable basic materials (score 5.96); (b) ergonomic design (score 5.95) and additional components (score 5.37). The results of comparing with competitor products show that the product developed is superior.Keywords – furniture, minimalist, wall study table, QFD
