Redesign and Improvement of Pottery Spinner to Increase Worker Producivity

Abstract

Many small industries produce handicrafts related to art in Bali, one of which is pottery. Pottery is an object made of clay which is formed and then burned to be a unique shape such as: jugs, glassware, cauldron, brazier, piggy bank, and other objects. The process of producing pottery required the complex steps, from preparing clay, printing by turning, drying and burning. The main difficulty of pottery producers is in the process of forming shapes which involved the rotating spinner. Most of small industries still use the manual spin control to rotate clay bucket holder. This research aims to redesign of a rotating spin machine from the existing pottery industries to increase the productivity. The sample was overtaken from 12 craftsmen in Singakerta Village, District of Ubud Gianyar, Bali. Sample P0 was given to craftsmen is still used the old design and P1 was given to sample modified and redesigned the old machine with added automatic control of rotating spinner. Workload is calculated based on the worker's pulse rate which is measured using a pulse meter. Research data were analyzed using descriptive and inferential statistics. T-test method was performed to analyzing the differences range between groups P0 and P1 at significance level of 5%. The results showed a workload was decreased from heavy to moderate by 12.09%. Production rate was increased by 282.1%, and productivity increased by 334.6%

Rancang Bangun Mesin Pemotong Serba Guna Hemat Energi Penunjang Produktifitas Ukm Kerupuk

“…Produktivitas dihitung berdasarkan output produksi dibagi waktu yang dibutuhkan untuk menghasilkan produk [4]. Proses produksi akan berlangsung secara optimal jika tugas, organisasi dan lingkungan kerja sesuai dengan kemampuan, perijinan dan keterbatasan pekerja [5]. Alasan UKM tidak menggunakan mesin bantu adalah tingginya biaya penggunaan mesin.…”
