Abstract

Komposisi timbulan sampah perkotaan di Indonesia didominasi oleh biowaste. Emisi gas rumah kaca (GRK) yang dihasilkan dari pengelolaan sampah adalah 8% dari total emisi GRK di Indonesia. Dalam sektor ini, biowaste merupakan salah satu penyumbang terbesar emisi GRK. Namun, pengolahan biowaste di Indonesia masih belum optimal. Teknologi pengolahan yang umum diterapkan adalah landfilling. Padahal, landfilling menghasilkan emisi GRK relatif lebih besar dari teknologi pengolahan lainnya. Teknologi biokonversi berpotensi baik dalam pengolahan biowaste karena secara umum lebih sederhana dan tidak membutuhkan banyak pengolahan awal. Studi pustaka ini membahas teknologi pengolahan biowaste dengan biokonversi dan potensi timbulan GRK. Teknologi yang dibahas adalah landfill, komposting, dan anaerobic digestion. Kajian pustaka dilakukan dengan mengumpulkan data dan informasi dari studi dan penelitian terdahulu mengenai mekanisme proses, aspek teknis, dan potensi timbulan GRK setiap teknologi. Hasil kajian pustaka digunakan sebagai dasar dari penyelesaian studi kasus berupa penentuan teknologi pengolahan biowaste yang optimal berdasarkan aspek teknis dan potensi timbulan GRK di Kota Surabaya. Potensi GRK dihitung dengan persamaan dari IPCC 2006 yang diadopsi dari Emission Quantification Tool (EQT) IGES. Penentuan teknologi pengolahan yang paling optimal pada studi kasus dilakukan dengan Analytic Hierarchy Process (AHP). Kesimpulan yang dapat diambil dari studi ini adalah urutan teknologi terpilih berdasarkan kajian yang telah dilakukan dan opini dari stakeholder terkait. Urutan teknologi yang paling sesuai diterapkan di Surabaya berdasarkan aspek teknis dan lingkungan adalah two stage AD, single stage AD, controlled landfill, sanitary landfill, in-vessel composting, BSFL composting, windrow composting, aerated static pile composting, dan vermicomposting. ============================================================================================ A large percentage of solid waste generation in Indonesia consists of biowaste. Greenhouse gas emissions of waste handling take 8% of total greenhouse gas produced in Indonesia. In this sector, biowaste is one of its major contributor. However, biowaste treatment in Indonesia is not yet optimal. Landfilling is still commonly used, although the greenhouse gas emitted from this technology is relatively abundant. Bioconversion technologies have great potential to be applied to treat biowaste because they are generally more convenient and does not require any advanced pre-treatment. This study discussed bioconversion as biowaste treatment technology and the potential of greenhouse gas emissions. The technologies discussed are landfill, composting, and anaerobic digestion. Literature study consisted of some past research about process mechanism, technical aspect, and potential of greenhouse gas of each technology discussed. The information gathered is applied to solve the case study of determining the most suitable biowaste treatment technology to be used in Surabaya City based on technical aspect and potential of greenhouse gas emissions. Potential of greenhouse gas emissions is calculated using equations from IPCC 2006 which was adopted by the Emission Quantification Tool (EQT) IGES. Lastly, the technology is determined using Analytical Hierarcy Process (AHP) method by applying opinions of related stakeholders. This study ultimately concluded the most suitable technology to be applied based on the literature study and the opinions of stakeholders. The sequence of the most suitable technology to be applied for biowaste treatment in Surabaya City is two stage anaerobic digester, single stage anaerobic digester, controlled landfill, sanitary landfill, in-vessel composting, BSFL composting, windrow composting, aerated static pile composting, and vermicomposting.
