Waste Reduction Through Integrated Waste Management Modeling at Mustika Residence (Tangerang)

Abstract

In Indonesia, there are classic issues about waste that are highlighted due to the country's critical conditions. Uncontrolled population growth and regional development have led to massive waste production. One popular practice in waste management is located at integrated waste management site (TPST). This practice has been implemented successfully by TPST Mustika Iklhas, a small community operation in Tangerang. Though different from previous operations, its success is achieved by active community participation, far away from government intervention. This study looks at management practices in TPST Mustika Ikhlas. The method used to address real and complex problems is called system dynamics. This method uses life cycle thinking to address the waste management practice in Mustika Residence. Once the model was constructed, a simulation was carried out within 1,080 days. In this study, exponential behaviors were generated in the main variables such as waste, inorganic waste, and compost. However, organic waste exhibited oscillation behavior due to its processing time needed to convert to compost. From the results and discussion, we conclude that integrated waste management in TPST Mustika Ikhlas has been effective in reducing waste through conversion to inorganic waste and compost. Intervention to Business-As-Usual (BAU) should focus on two leverage variables: retribution and TPST cash flow.

Manajemen Lingkungan Masyarakat Melalui Pendekatan Culture and Behavior di Pesisir Timur Sumatera Utara

“…Konsep pengelolaan sampah padat melalui pendekat budaya belum dijadikan alternative solusi dari masalah global tentang sampah saat ini, penerapan teknologi dan berbagai metode juga sudah banyak dikembangkan salah satunya adalah mesin penghasil platik yang mudah hancur dalam hitungan beberapa tahun, namun manusia sebagai pelaku utama dalam pencipta dampak konsumsi tidak dilibatkan sebagai aktor pemecah masalah dalam mengatasi tumpukan sampah, manusia hanya menjadi pelaku dalam pemusnahan sampah tapi bukan sebagai agen perubahan perilaku untuk merubah keadaan. Budaya adalah sesuatu yang berakar, memiliki nilai yang kuat dan sulit dirubah kecuali terjadinya sebuah revoluasi besar-besaran tentang perilaku manusia namuan hal ini sulit terjadi (Johannes, 2018). Manusia memiliki kemampuan adaptasi yang baik pada tempat tinggal dan bentuk interaksi sehingga manusia memiliki potensi dalam merubah suatu keadaan melalui nilai teguh yang di pegang kuat, kearifan lokal atau biasa di sebut pengetahuan lokal adalah suatu pola pemahaman sederhana tentang suatu aktivitas yang dijalankan secara terus menerus dan bersifat diturunkan dari bentuk cerita dan pengalaman (Iacovidou and Voulvoulis, 2018), hanya saja nilai empirisnya perlu diuji, tapi kebanyakan sebuah kearifan lokal tentang pengelolaan lingkungan, sikap manusia dalam berinteraksi, cara konsumsi makanan dan pola hidup biasanya mengandung nilai kebaikan dan fenomena sebab akibat.…”
