Abstract

Waste is a remnant produced from human activities such as; household, commercial, office, industrial, etc. Waste is considered to have no value because it cannot be reused so that some people do not care about the impact of waste. The accumulation of waste that accumulates every day will harm the environment and society. The incoming waste to be processed at Talangagung Landfill comes from: Settlements, markets, Sub-Landfill, hospitals, offices, companies and highway services. In 2018 the Talangagung landfill receives 48,063.37 tons/year of waste. The largest source of waste entering the Talangagung landfill comes from settlements of 54%, the market by 22%, sub- landfill by 15%. Talangagung landfill educational tourism is one of the pilot landfills that use a controlled landfill system to manage waste to minimize negative impacts on the environment and society. The waste that enters the Talangagung landfill will be processed into biogas. Renewable energy produced from Talagagung landfill in the form of methane gas arising from waste decay. The potential for waste management into biogas can be calculated using the scholl canyon method from Talangagung landfill waste data in 2018. The results of the calculation of the gas produced are 183,558 m3 / year. The gas produced is assumed to only be captured at 75% with the composition of methane gas at 50% -55% of the total gas produced. The resulting methane gas has decreased to reach 31,897.6 tons/year in the 40th year. This is because waste that experiences an anaerobic phase experiences nutrient reductionKeywords: Controlled landfill, Renewable energy, Methane, Waste

Abstract

Peningkatan jumlah Daerah Aliran Sungai (DAS) kritis termasuk DAS Brantas adalah salah satu masalah utama yang harus diselesaikan dalam pengelolaan lingkungan di Indonesia. Untuk menyelesaikan permasalahan ini diperlukan solusi dengan pendekatan perencanaan pengelolaan DAS secara terpadu. Dalam penyusunan perencaan tersebut, landasan berfikir pemangku kepentingan merupakan fundamen penting yang harus perhatikan. Penelitian ini bertujuan untuk menganalisis landasan berfikir pemangku kepentingan untuk penyusunan perencanaan pengelolaan sub DAS Brantas hulu wilayah Kota Batu. Metode yang digunakan adalah metode survei dengan pendekatan kuantitatif. Analisis data dilakukan melalui metode Profesional Judgement dengan menggunakan analisis Ziel Orientierte Projekt Planung (ZOPP). Hasil penelitian ini menunjukkan kalau landasan berfikir penyusunan perencanaan pengelolaan sub DAS Brantas hulu wilayah Kota Batu terdiri atas 4 tahap, yaitu: analisis pemangku kepentingan, analisis masalah, analisis tujuan dan analisis penyelesaian masalah. Faktor pendorong utama untuk penyusunan rencana pengelolaan sub DAS Brantas hulu antara lain adalah adanya komitmen dari pemangku kepentingan, sementara faktor utama penghambatnya adalah belum adanya koordinasi dari pemangku-pemangku kepentingan tersebut. Penelitian ini menunjukkan kalau tersusun dan terdokumentasinya landasan berfikir dalam penyusunan rencana pengelolaan sub DAS Brantas hulu wilayah Kota Batu menjadi hal yang sangat penting untuk kepentingan berbagai pihak seperti legislatif, eksekutif, yudikatif, swasta, tokoh masyarakat, perguruan tinggi dan lembaga swadaya masyarakat. Saran yang diberikan dari hasil penelitian ini adalah perlu adanya perubahan pola berfikir dalam penyusunan rencana pengelolaan dari sektoral menjadi terpadu dan dari reaktif ke antisipatif.

Abstract

The objective of this study is to find out the availability of water, the distribution of spring locations, the amount of clean water needs, and the right strategy to maximize the management of clean water in Passo Village. To obtain the right management strategy, the SWOT method was applied in this study. Based on the results of SWOT analysis, it was found that the proposed alternative management strategy related to stable growth is directed at strengthening collaborative and participatory management by relying on the strength of costs or funds owned by the government and opportunity from society in management implementation. The three strategies consist of developing individual or family water management sites into society-based ones, improving water quality by maintaining vegetation around the springs, and developing sites for optimal water management by creating cooperation between society and the government in order to continue to meet the needs of society. The three strategies are expected to maximize society-based clean water management in Passo Village in Baguala Sub-District, City of Ambon.Keywords: Strategy, Water Management, SWOT
