Analisis Karakteristik Sampah Nonorganik Dan Strategi Penguranganya Di Kawasan Suci Laut Provinsi Bali
Summary
Survey of inorganic litter in four sacred coastal areas of Bali found that 56% was inorganic material with soft plastics dominant in buffer and beach zones, while community perceptions of waste management did not match actual litter conditions. This study directly informs microplastic research by documenting plastic litter accumulation patterns in high-footfall coastal environments, where fragmentation of soft plastics is a primary source of secondary microplastic generation.
Sacred coastal areas in Bali face serious challenges due to litter accumulation from religious and tourism activities, particularly plastic waste that threatens environmental sustainability and spiritual values. This study aims to analyze the characteristics and distribution of inorganic litter, evaluate community perceptions, and formulate plastic waste reduction strategies aligned with local values and the needs of sacred sites. The research employs a quantitative approach, collecting litter data from three zones (temple, buffer zone, and beach) across four sacred coastal areas in Bali (Goa Lawah, Er Jeruk, Sakenan, and Petitenget). Litter was analyzed based on density, distribution, and physical characteristics. Community perceptions were assessed through mean analysis of closed-ended questionnaires, while priority strategies were determined using the Analytic Hierarchy Process (AHP). The results of this study is show that litter in Bali's sacred coastal areas is dominated by inorganic materials (56%), with soft plastics most prevalent in buffer zones and beaches. Most litter items were found intact except for plastic foam. Size classes were predominantly 3-7 (2-4 cm², 4-8 cm², 8-16 cm², 16-21 cm², and >22 cm²). While community perceptions of waste management were rated good (average score 3.60-3.72), a gap existed between perceptions and actual conditions. AHP analysis revealed location-specific priorities: law enforcement in Goa Lawah, community participation in Er Jeruk/Sakenan, and segregated waste management in Petitenget.
