Abstract

ABSTRACT: Marine tourism is one of the region's leading sectors, significantly contributing to Regional Own-Source Revenue (PAD - Pendapatan Asli Daerah). However, tourist areas also generate waste from tourists or visitors. This study aims to identify and analyze the waste generation and composition in the Pasir Putih Beach tourist area and assess the potential for waste reduction. The research was conducted over four months (March-June 2024), with the study site located at Pasir Putih Beach. Waste generation measurements were categorized by source type: point sources and line sources. Point sources include restaurants and food stalls within the Pasir Putih Beach area, while line sources refer to marine debris along the shoreline. Waste generation from point sources was measured using the standard method outlined in SNI 19-2964-1994, which details the sampling and measurement of urban waste generation and composition. Based on the study's findings, 15 different types of marine debris were identified at Pasir Putih Beach. The most abundant components of marine debris were coconut shells (27.59%), wood (18.32%), and recycled plastic (14.61%). Organic waste generated by restaurants or cafés at Pasir Putih Beach amounted to 8 kg per unit per day, with a waste density of 0.007125 kg/m³ for cafés, while food stalls had a waste density of 0.00675 kg/m³. The average waste produced by food stalls at Pasir Putih Beach was 8 kg per unit per day, with a waste density of 0.00675 kg/m³. Waste from tourist activities, including cafés, restaurants, and food stalls, was primarily composed of kitchen waste and food leftovers, along with garden waste, such as leaves, accounting for 13.48% of the total. This waste can be processed through biological methods, such as composting or biodigesters.

Abstract

ABSTRACT: The coastal area of Makimi Village, Makimi District, Nabire Regency is an important nesting site for the olive ridley turtle (Lepidochelys olivacea) with unique characteristics as its nests are located near residential areas that help protect the nesting sites. This research aims to determine the physical and biological parameters of the olive ridley turtle nesting habitat in Makimi Village, Makimi District, Nabire Regency. The research was conducted during the nesting season from February 1 to August 31, 2023. The results showed that The physical characteristics of Makimi Village Beach include an average beach width of 30 m, with a beach category ranging from sloping (6-39°) to steep (with a slope greater than 40°). The most common substrate in the nesting area is fine sand (60.05%), followed by very fine sand (25.77%). There were 11 nesting holes with temperatures ranging from 27°C to 31°C, with an average of 28.12°C to 30.87°C. The pH levels ranged from 5.5 to 7, and the average humidity was between 50% and 74%. The types of beach vegetation in the olive ridley turtle nesting area are dominated by six plant species: goat's foot creeper (Ipomoea pescaprae), waru tree (Hibiscus tiliaceus), pongam tree (Pongamia pinnata), sea almond (Terminalia catappa), coastal she-oak (Casuarina equisetifolia), and coconut palm (Cocos nucifera).
