Study on Possibility of Cleaner Production Application at Small Scale Bakery Industry in Pekalongan Indonesia

Abstract

This study analyzed the opportunities for implementing a cleaner production of small bread industries. The research begun with identification of the process stages, problems and opportunities for the application of cleaner production as well as an analysis of alternative feasibility of environmental, technical and financial aspects. The study found a variety of problems such as no special fermentation chambers, no determination of fermentation time, scattered flour, smoking workers, spilt dough, inappropriate placing goods, and the use of lights during the day, untreated eggshells, leftover bread and off-grade bread, the liquid waste from the washing process goes into the water body, unsold bread, and does not have a halal certificate. The recommended alternatives are making space and determining fermentation time, Good Manufacturing Practices, lighting re-design during the day, eggshells process into fertilizer, the remaining slices of bread and off-grade bread are processed into bread crumb flour, four stages of washing, submitting halal certificates, and bread waste flour as animal feeds. The implementation of cleaner production can: (i) increase bread production of 21.19 to 21.80 ton/month, (ii) reduce washing water from 4,000 to 3,600 liters/month, (iii) cut electricity from 1,613 to 1,593 kWh/month, (iv) improve treated solid waste from 3.27 to 3.43 tons/month, and (v) increased sales of fresh bread to 34,996 packs/month and sweet bread 14,560 packs/month. The total profit that can be obtained by applying cleaner production is Rp 21,324,000 per month. Keywords : cleaner production, feasibility analysis, small bread industry DOI : 10.7176/CPER/59-01
