Abstract

Garment industry often faces many problems such as low productivity, long lead time production, high product rework and rejection, improper line balancing, and inflexible style running changeover. The aim of this research is to implement one of the lean concept tools namely one piece flow. This study focuses on Sewing Department of Man Shirt Unit in a Garment Company in Central Java, Indonesia. The study of this paper includes the description of garment manufacturing process flow and comparison between the batch production system and one-piece flow system. The performance criteria used in this study is the total processing time, the basic pitch time, the production targets and the throughput time. The time study is used as the measurement method to determine the cycle time and throughput. From the analysis, one piece flow system performs better in term of total processing time, the basic pitch time and the throughput time and the target achievement than batch production system. The total processing time and pitch time reduced by 6.42 % and 0.385% respectively. The daily target quantity increased by 8.609% and tThe troughput time of 1 piece of good garment in assembly line reduced from 3.35 hour to 0.915 hour.

Abstract

Baby diaper waste management is becoming an increasingly pressing environmental issue due to the high use of disposable diapers in the community. The lack of waste management infrastructure and low environmental awareness are the main obstacles in increasing public participation in the collection of baby diaper waste. This study aims to identify the factors that influence the level of consumer willingness to collect baby diaper waste and determine the expected compensation expected by consumers. Multiple ordinal regression and Contingent Valuation Method (CVM) were used to achieve these objectives. The results of multiple ordinal regression analysis show that several independent variables have a significant influence on community participation in baby diaper waste management, including Environmental Awareness (X1), Infrastructure Availability (X2), Knowledge and Education (X3), Economy (X4), Policy and Regulation (X6), Ease of Access and Facilities (X7), and Culture and Social Norms (X8). Meanwhile, Community Involvement (X5) did not show a significant effect. Of these variables, Infrastructure Availability (X2), Culture and Social Norms (X8), and Policy and Regulation (X6) show the most significant influence. Based on the CVM results, the average expected compensation for community participation is Rp1,250 per kilogram of dry diaper waste. These findings suggest the importance of improving waste management infrastructure as well as supportive policies to encourage community participation. In addition, attractive economic incentives need to be implemented to strengthen community involvement in the collection of baby diaper waste. This study provides insights for stakeholders in formulating policies that support the development of effective and sustainable community participation-based waste management programs.
