Abstract

Most of the area in Klungkung Regency has a waste management system that needs to meet technical requirements regarding the compartment, sorting, collecting, transporting, and processing. Coverage of handling urban waste is still far from the target of 80% in 2019 (46% in 2013), and the amount of waste generation that is still recycled is still minimal (4.95 m3 in 2017). This research aims to make a master plan or strategy implemented to improve service coverage and the quality of solid waste management in the future. This research was conducted by conducting a direct survey and secondary data collection. The strategy adopted is to increase the utilization of waste infrastructure and facilities; increasing the capacity of solid waste facilities according to service targets; improving the quality of landfill management in the direction of sanitary landfills; developing regional final processing site management, and applying waste handling technology that is appropriate and environmentally friendly. The Millennium Development Goals (MDGs) contain the seriousness of improving sanitation conditions, which require increased public access to sanitation facilities in half of the population without access to sanitation. Increased population access to proper sanitation (domestic wastewater, solid waste and environmental drainage) to 100% at the level of basic needs.

Abstract

Efficient waste management remains a pivotal challenge at Indonesian tourist sites. This study conducts a literature review to dissect the prevalent issues and necessary policy interventions in recycling waste within these locales. Results reveal that current policies on plastic usage are inadequately enforced, largely due to insufficient awareness and stakeholder engagement. Key barriers include a lack of infrastructure, minimal community participation in recycling initiatives, and limited regulatory oversight. To address these issues, the study suggests amplified enforcement of existing plastic regulations, enhancement of waste management infrastructure, and a boost in community involvement. The study advocates for a cohesive approach involving government authorities, tourism businesses, waste management entities, and local communities to heighten accountability and environmental stewardship. It is posited that with collective effort, waste management in Indonesian tourist spots can be significantly improved, thus yielding environmental and social dividends.

Abstract

This study explores the potential for managing biodegradable marine debris waste in Jakarta City through composting, aiming to reduce and treat this waste effectively. In Jakarta, river debris predominantly consists of materials that degrade easily and are biodegradable. Composting represents the most straightforward method for processing this type of organic waste. The study's objective was to evaluate the feasibility of composting organic biodegradable river debris as a waste management strategy. Data collection was conducted at Emplacement Pluit, utilizing random sampling with the four quadrants method. Out of the total river debris generated daily, which amounts to 309 m³, approximately 9.07 m³/day was found suitable for composting. The composting process resulted in a significant reduction of river debris volume by 50.15% within a 30-day detention period. This process was facilitated by mesophilic microbial activity at temperatures between 30-38°C. During the first two weeks, the composting environment remained acidic until the pH stabilized to a normal range between 6.8 and 7.49. A notable observation was the high initial water content of the river debris, recorded at 53.846%, which only reduced to 42.857% by the end of the 30-day decomposition period. Therefore, a pretreatment step is recommended to optimize the water content before composting. Despite these challenges, the compost produced met the required standards set by SNI 19-7030-2004. This study underscores the importance of managing biodegradable organic waste at its source to alleviate the burden on landfills, which are currently operating beyond their capacity.

Abstract

Di Kota Kediri, kondisi sosio-ekonomi yang beragam berpengaruh signifikan terhadap akses layanan sanitasi dan sering kali terkait dengan tantangan di kawasan yang berpenduduk padat dan kurang mampu secara ekonomi. Penelitian ini bertujuan untuk menganalisis dampak faktor-faktor sosio-demografi terhadap penggunaan tangki septik dan Instalasi Pengolahan Air Limbah (IPAL). Menggunakan data sekunder yang diolah melalui model regresi linier berganda, penelitian ini meneliti hubungan antara lama sekolah, kondisi ekonomi, dan metode pengelolaan air limbah oleh penduduk. Variabel yang digunakan meliputi durasi pendidikan (X1), kondisi ekonomi (X2), serta metode pembuangan air limbah ke perairan terbuka atau ke dalam tanah (X3 dan X4). Temuan menunjukkan bahwa panjang pendidikan, status ekonomi, dan metode pembuangan signifikan mempengaruhi keputusan menggunakan tangki septik atau IPAL. Hasil penelitian ini menekankan perlunya Pemerintah Kota Kediri untuk meningkatkan infrastruktur sanitasi sebagai komponen krusial dalam pengembangan ekonomi dan peningkatan kesejahteraan publik. Dianjurkan penerapan analisis biaya-manfaat secara sistematis untuk membenarkan alokasi dana terhadap peningkatan sanitasi.

Abstract

This study examines the characteristics and utilization potential of plastic waste, particularly Polyethylene Terephthalate (PET), collected from the Kebon Melati Reservoir in Central Jakarta. Urban reservoirs in Jakarta increasingly serve as accumulation points for floating waste, contributing to drainage obstruction and aquatic pollution. Waste samples were collected using a grab sampling method at multiple accumulation points, followed by manual sorting and moisture content analysis. The results showed that biodegradable waste accounted for 64.1% of total collected waste, while plastic waste represented 35.9%. Within the plastic fraction, PET was identified as the dominant polymer type, followed by High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE). Moisture analysis indicated that PET had the lowest moisture content (3.4%) compared with HDPE (5.3%) and LDPE (6.3%), while biodegradable waste had a significantly higher moisture content (78.1%). These findings demonstrate that PET has strong potential for mechanical recycling, pyrolysis, and Refuse-Derived Fuel (RDF) production due to its low moisture content and stable polymer structure. This study highlights the importance of reservoir-based plastic recovery as a strategy to support circular economy initiatives and improve urban waste management in Jakarta.
