Abstract

Peningkatan volume sampah laut di wilayah pesisir Jakarta merupakan permasalahan lingkungan yang serius, sementara kebutuhan energi terbarukan terus meningkat seiring upaya pengurangan ketergantungan pada energi fosil. Penelitian ini bertujuan menganalisis potensi energi sampah laut sebagai dasar pengembangan pembangkit listrik berbasis ekoteknologi di wilayah pesisir Jakarta, dengan lokasi pengambilan sampel di Kali Adem dan Muara Angke, Kecamatan Penjaringan. Penelitian menggunakan pendekatan kuantitatif deskriptif-analitis melalui survei komposisi sampah (metode kuadran 1×1 m pada 6 titik sampling), pengujian laboratorium karakteristik fisik-kimia (kadar air, kadar abu, kadar garam), serta perhitungan potensi energi berdasarkan data sekunder nilai kalor yang dikoreksi dengan hasil uji laboratorium. Hasil penelitian menunjukkan sampah plastik mendominasi komposisi sampah laut (78,64% dari 220 item), diikuti sampah organik (10,00%), kain (4,09%), karet (3,64%), logam, dan residu lain (masing-masing 1,82%). Pengujian laboratorium menunjukkan karakteristik fisik-kimia sampah laut berbeda signifikan dari sampah darat sejenis, dengan kadar air umumnya lebih rendah (0,223–7,580%) akibat pengeringan alami di pesisir, serta kadar garam (1,33–4,00‰) sebagai parameter khas sampah laut yang berimplikasi pada potensi korosi sistem konversi energi. Total energi kalor terkoreksi diestimasi sebesar 598.608 MJ/hari, dengan estimasi daya listrik 1,91 MW (insinerasi), 2,77 MW (gasifikasi), dan 1,56 MW (pirolisis). Berdasarkan kesesuaian skala operasional, karakteristik bahan baku, dan validasi benchmark literatur, pirolisis direkomendasikan sebagai teknologi konversi energi yang paling sesuai untuk sampah laut di wilayah penelitian. Penelitian ini diharapkan menjadi dasar ilmiah pengembangan pemanfaatan sampah laut sebagai sumber energi terbarukan berbasis ekoteknologi, sekaligus mendukung pengelolaan sampah laut berkelanjutan dan perumusan kebijakan energi bersih di kawasan pesisir.

The increasing volume of marine waste along Jakarta's coastal areas represents a serious environmental problem, while the growing demand for renewable energy underscores efforts to reduce dependence on fossil fuels. This study aims to analyze the energy potential of marine waste as a basis for developing ecotechnology-based power generation in Jakarta's coastal areas, with sampling conducted at Kali Adem and Muara Angke, Penjaringan District. This research employed a descriptive-analytical quantitative approach, comprising a waste composition survey (1×1 m quadrant method at six sampling points), laboratory testing of physical-chemical characteristics (moisture, ash, and salt content), and energy potential calculations based on secondary calorific value data corrected using laboratory test results. The results show that plastic waste dominates the marine waste composition (78.64% of 220 identified items), followed by organic waste (10.00%), textiles (4.09%), rubber (3.64%), metal, and other residue (1.82% each). Laboratory testing revealed that the physical-chemical characteristics of marine waste differ significantly from equivalent land-based waste, with generally lower moisture content (0.223–7.580%) due to natural drying in coastal environments, and salt content (1.33–4.00‰) as a distinctive parameter of marine waste with implications for corrosion risk in energy conversion systems. The corrected total heat energy was estimated at 598,608 MJ/day, with estimated electrical output of 1.91 MW (incineration), 2.77 MW (gasification), and 1.56 MW (pyrolysis). Considering operational scale suitability, feedstock characteristics, and validation against literature benchmarks, pyrolysis is recommended as the most suitable energy conversion technology for marine waste in the study area. This research is expected to serve as a scientific basis for developing marine waste utilization as an ecotechnology-based renewable energy source, while supporting sustainable marine waste management and clean energy policy formulation in coastal regions.
