Abstract

Daun pisang sering menjadi limbah dari aktivitas manusia. Meskipun demikian, daun pisang memiliki kandungan karbon yang membuatnya berpotensi sebagai bahan bakar. Namun, kendalanya adalah kadar air yang tinggi dalam daun pisang, yang dapat menghambat efektivitasnya sebagai sumber energi. Untuk mengatasi hal ini, diperkenalkan proses Biodrying. Melalui Biodrying, mikroorganisme digunakan untuk mengurangi kadar air dalam limbah organik, seperti daun pisang, sehingga meningkatkan potensinya sebagai bahan bakar. Penelitian ini dilakukan untuk menganalisa seberapa efektif Biodrying dalam meningkatkan nilai kalor daun pisang. Selama proses Biodrying, terjadi pengurangan massa dan kadar air pada daun pisang. Sejak hari pertama, suhu dalam tumpukan sampah daun pisang meningkat, menandakan aktivitas mikroorganisme, dengan pH yang tetap normal. Hasil akhir menunjukkan bahwa kadar air daun pisang berkurang sekitar 45,3% hingga 50,49%, dan nilai kalor yang dihasilkan mencapai standar pellet biomassa, yaitu antara 19.9 MJ/kg hingga 21.4 MJ/kg. Ini menunjukkan bahwa daun pisang, setelah melalui proses Biodrying, memiliki potensi besar untuk dimanfaatkan sebagai sumber energi yang efisien.

Abstract

River debris in Jakarta is generated in several locations by conventional transportation. Waste transportation with traditional models is usually not time-efficient, primarily when river debris is generated every time. Transport systems that can be used for river debris include compactor systems, pre-compactor systems, and baller systems. This research uses literature study and secondary data in determining alternatives. Meanwhile, the alternative selection was carried out using the Multi-Criteria Decision Making (MCDM) method. This study uses four criteria for selecting alternatives: initial capital, type of transport container, operation and maintenance, and processing capability. The utility value of waste transportation with compaction and pre-compacting systems does not significantly have utility values of 0.722 and 0.833, respectively. At the same time, the baller system has a utility value of 0.222. This shows that the compacted system is more suitable to be applied to SPA river debris in Jakarta. The presence of a pr-compactor can also reduce the water content in-river debris.

Abstract

This study critically evaluated the potential of Refuse Derived Fuel (RDF) as a sustainable substitute for coal in the cement manufacturing process. Using Emplacement Pluit's waste as a primary source, three distinct RDF variations were analyzed: RDF A (comprised purely of PET Charcoal), RDF B (a 50-50 combination of PET Charcoal and organic waste), and RDF C (solely organic waste). Among the parameters evaluated were moisture content, ash content, and calorific value. The results indicated RDF A's superior quality, with a moisture content of 2.6%, ash content of 0.7%, and a calorific value of 25.1 MJ/kg. In stark contrast, RDF C exhibited a high waste reduction potential at 80.5%, but its calorific value fell short of Korean standards. RDF B, balancing quality and reduction potential, achieved a 98.9% waste reduction and met Korean RDF standards, making it the most viable alternative to coal in cement production. The study underscores the significant potential of integrating RDF in industrial practices, particularly cement kilns. It offers insight into optimizing waste management strategies in line with the 'zero-waste' vision.

Abstract

The waste from the river is one of the obstacles in managing the Bengawan Solo River, Surakarta City. River debris is usually collected in tributaries so as not to carry the pollutant load to the watershed, causing flooding, and then transported to the Final Processing Site (TPA). This study aims to analyze the waste transportation system from the source to the landfill. This research was conducted by direct observation and using Multi-Attribute Utility Theory (MAUT) for determination. Alternative waste transportation used are haul container system (HCS) and stationary container system (SCS). The criteria used are the number of ritations, price, ease of transportation, potential damage, maintenance, and type of container. Based on the weighting results on the MAUT analysis, transportation with the SCS method has a higher weight than the HCS method.

Abstract

Dalam konteks peningkatan keberlanjutan lingkungan, biodiesel muncul sebagai solusi energi alternatif yang menjanjikan, diperoleh dari sumber terbarukan seperti minyak tumbuhan atau lemak hewan. Upaya pengurangan ketergantungan terhadap bahan bakar fosil di Indonesia dapat ditempuh melalui adopsi biodiesel. Penelitian ini bertujuan untuk menganalisis potensi pemanfaatan minyak jelantah, yang merupakan limbah dari aktivitas memasak para pedagang kecil, sebagai bahan baku dalam produksi biodiesel. Dengan metode penelitian kuantitatif yang mengandalkan data survei dan tinjauan literatur, studi ini menyelidiki kebutuhan infrastruktur dan potensi konversi minyak jelantah menjadi biodiesel. Temuan menunjukkan bahwa dari data survei responden, minyak jelantah dapat dikonversi menjadi biodiesel dengan kapasitas sekitar 0,66 liter biodiesel per hari. Proses pengolahan minyak jelantah menjadi biodiesel ini berpotensi menggantikan penggunaan lampu 15 Watt selama sekitar 10 hari dengan biaya operasional sebesar Rp3.655 untuk dua orang. Penelitian ini mengungkapkan bahwa pengolahan minyak jelantah menjadi biodiesel tidak hanya mendukung inisiatif zero waste di kalangan rumah tangga tetapi juga menyajikan alternatif energi yang ekonomis dan ramah lingkungan.

Abstract

Urban public health initiatives rely heavily on community participation to ensure success and sustainability. This study explores the socio-demographic determinants of community engagement in the public health initiatives of Koja Subdistrict, Jakarta. A cross-sectional survey was conducted, employing both qualitative interviews and quantitative questionnaires to gather data from a representative sample. Binary logistic regression was used to analyze the data, focusing on aesthetics, public health sanitation performance, community socialization, gender, age, and education. The findings reveal that aesthetic considerations, perceived sanitation performance, socialization practices, and demographic factors significantly influence the willingness to participate. Aesthetics and community socialization positively impacted engagement, while perceived high sanitation performance paradoxically discouraged individual participation. Furthermore, demographic factors such as gender, age, and education level showed varying degrees of influence, with gender disparities and higher education correlating with increased engagement. This study contributes to understanding public health participation dynamics and offers insight into designing tailored community engagement strategies. Policymakers and health officials can leverage these insights to effectively enhance community involvement and address public health challenges.

Abstract

Leachate is one of the results of the waste degradation process that can pollute the environment. Leachate is usually treated by biological processes, including aerobic processes that require sufficient oxygen. Oxygen transfer by aeration process is one way to consider gas transfer coefficient (KLa). This study aims to determine the gas KLa kinetics in leachate. This study used a chemical oxygen demand (COD) concentration limit of 100 mg/L. The oxygen flow rates used in this study were 1 L/minute and 1.5 L/minute. The main parameter measured in this study is dissolved oxygen (DO) which is measured by a DO meter every minute. The final DO in this study can be as high as 4 to 6 mg/L. The KLa values in this study show values at the flow of 1 and 1.5 L/min, respectively 0.0095/min and 0.017/min. These results also show that the detention time required for 1 and 1.5 L/min flow rates is 1.75 hours and 0.96 hours. This indicates that the greater the flow rate is given to the oxygen transfer process, the greater the flow rate the KLa value will increase. This will also affect the volume required for the oxygen transfer process. In addition, further research is needed with more diverse variations to further determine the appropriate detention time in leachate processing.

Abstract

The COVID-19 pandemic brought an upsurge in Personal Protective Equipment (PPE) usage, leading to emergent challenges in its post-use management, especially in urban centers like Jakarta. This study conducted a quantitative exploration, employing simple random sampling techniques, to investigate Jakarta citizens; perceptions of PPE waste management. Two significant factors, "Safe Management and Regulation" and "PPE Waste Handling," were identified as paramount in addressing the issue. Through cluster analysis, the population was segmented into three distinct clusters: "Regulatory-Driven Safety Respondents," "Operational PPE Focus Respondents," and "Minimal Management Respondents." The study also unveiled a notable influence of socioeconomic variables on PPE waste management attitudes, particularly occupancy and income. These findings give policymakers, urban planners, and researchers invaluable insights, emphasizing the need for a dual-focused approach encompassing regulatory and operational strategies tailored to specific demographic segments for optimal impact.

Abstract

Maluku Province is an area with minimal access to sanitation because of its archipelagic location. Access to sanitation is one indicator of sustainable development goals (SDGs) that must archive in 2030. To achieve sustainable universal sanitation access, an indicator is needed that can be used to make policies that can grow access to proper sanitation. This study aims to determine the factors that can improve sanitation in Maluku Province. The development of livable housing must also pay attention to access and proper sanitation. This study used secondary data to analyze multilinear regression of socioeconomic impact on access to sanitation. Economic growth affects people's welfare. Economic growth is usually followed by a reduction in poverty, an increase in the Human Development Index (HDI), and an expansion of employment opportunities. This study uses secondary data from 2006 to 2016. Integrating human development, reducing poverty, and increasing residential ownership is needed to increase Maluku Province's sanitation access. With improved policies and better master plans for improving the quality of social variables, this variable will also affect increasing access to sanitation in Maluku Province. Better policy and programs from the central and local governments should seek to reduce poverty levels to improve access to sanitation in Maluku Province.
