STAKEHOLDER COLLABORATION IN HOUSEHOLD ORGANIC WASTE MANAGEMENT IN SEMARANG CITY

Household organic waste presents a specific challenge for Semarang City, as its waste volume represents the highest proportion in Central Java Province. The rising accumulation of household organic waste has led to a continuous increase in the volume of waste disposed of at Final Processing Sites (TPA). Without active stakeholder support, achieving sustainability and a positive environmental impact in household organic waste management remains difficult.Although stakeholder involvement in waste management and the implementation of Supply Chain Management (SCM) are often discussed separately, there is still a lack of conceptual models that integrate these two perspectives within the context of household organic waste in Semarang. This study aims to examine stakeholder collaboration in the implementation of the supply chain for household organic waste management. The research utilizes a quantitative method approach. Primary data from 177 respondents-representing every sub-district (kelurahan) across the 16 districts of Semarang-were collected via questionnaires. Respondents were selected using the stratified random sampling method. Data analysis was conducted using the Partial Least Square (PLS) method through SmartPLS 4.0 software. The data for analysis consisted of scores from scale-based responses. The findings indicate that active stakeholder involvement is a key factor in improving system or organizational performance. In the context of the organic waste supply chain, SCM relies not only on technical and operational aspects but also on social support and collaboration between actors.
