Use of Solar Energy Hybrid Dryer with Techno-Ergonomic Application to Increase Productivity of Dodol Wokers in Buleleng, Bali

Abstract

Penglatan Village is one of dodol industrial centres in Buleleng Regency, Bali. Dodol is a balinese traditional snack that usually used for religion ceremonies offering or “sesajen”. Dodol’s making processes had several layer of stages, from making dough, stirring dough, packaging and drying dodol. Because the drying process is done with traditional work tools, this process cause several ergonomic problems. Based on preliminary research, the complaints that felt by dodol workers are pain in the neck, shoulders, back, waist, head, and hands. Therefore, productivity of workers are decreasing. This problem solved by designing a hybrid solar drying tools with the application of techno-ergonomic, appropriate technology concept (TTG) and from ergonomic science with the application of SHIP concept (systemic, holistic, interdisciplinary, participatory). This research use 20 people as sample. The sample performance is observed while working traditionally and using techno-ergonomic hybrid solar dryer tools. The measurements conducted three times which are First Period (PI), Second Period (PII), and Third Period (PIII) with interspersed time for rest. WOP (washing out period) is intended to eliminate residual effects. The data were analyzed with SPSS program with significance level of 0.05. Hopefully, with this solution will improve worker productivity.
