Abstrak

Seksi persampahan Kecamatan Manggala Kota Makassar saat ini masih menemukan banyak risiko yang umum terjadi pada supply chain pengelolaan sampah dari sumber sampah menuju Tempat Pembuangan Sementara (TPS) selanjutnya ke Tempat Pembuangan Akhir (TPA). Hal ini menyebabkan semakin meningkatnya volume sampah setiap hari karena kurangnya pemilahan sampah dari sumber sampah sehingga sampah di TPS berserakan akibat bak sampah tidak mampu lagi untuk menampung dan akhirnya TPA mengalami over kapasitas tanpa ada penangangan yang efektif untuk mengurangi volume sampah. Oleh karena itu perlu dilakukan penanganan pada risiko yang terjadi. Penelitian ini bertujuan untuk memberikan usulan strategi mitigasi yang berkelanjutan untuk mengurangi dampak risiko pada pengelolaan sampah dengan metode Delphi untuk mengidentifikasi potensial risiko. Menggunakan House of Risk (HOR) pada tahapan analisis dan evaluasi risiko untuk menentukan strategi mitigasi dan pengukuran index sustainability menggunakan Method Successive Interval (MSI) untuk dapat mengetahui status keberlanjutan dari strategi mitigasi yang telah diusulkan. Berdasarkan hasil penelitian diketahui bahwa terdapat 18 risk event dan 65 risk agent yang teridentifikasi. Selanjutnya dilakukan strategi mitigasi pada risk agent menggunakan 16 preventive action yang selanjutnya dilakukan pengukuran tingkat keberlanjutan masing-masing strategi, hasil dari pengukuran tersebut ditemukan 3 strategi yang statusnya sangat berkelanjutan, 10 strategi yang statusnya cukup berkelanjutan dan 3 strategi yang statusnya kurang berkelanjutan.
