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

This study concerns the design of a waste management system using the Material Flow Analysis (MFA) method in the city of Tasikmalaya. TPA Ciangir is the only landfill in Tasikmalaya, and its storage capacity has reached its maximum, necessitating improvements in waste management. The aim of this design is to determine an appropriate waste management system that can be implemented in Tasikmalaya. Based on observations and interviews, waste collection at TPA Ciangir in Tasikmalaya is conducted in small amounts, leading to a significant amount of household waste not being collected daily, resulting in waste accumulation and minimal transport to waste processing facilities. According to Permen PU Number 3 of 2013 and SNI 19-2454-2002, waste collection from the source should be conducted at least once every two days. Therefore, an evaluation and redesign of the waste management system based on technical aspects are needed. The best system selection will be carried out using the Analytical Hierarchy Process (AHP) method, which will then be recommended for application at TPA Ciangir in Tasikmalaya. Based on the calculations using the AHP method, scenario 3 scored the highest, at 1.676, using composting processes, RDF, and TPST-3R. From the design results, a total waste reduction of 81% was achieved, aligning with the government's target of a 70% waste reduction by 2020.

Abstract

Kendal District has two primary waste management facilities: the Pasar Kendal Composting House and the Jatirejo Composting House. This study meticulously evaluates the operational performance of these facilities throughout the 2021-2022 timeframe, uncovering a stark contrast in their waste processing achievements. In the year 2021, the Jatirejo facility managed to process only a paltry 0.35% of the total waste received, starkly juxtaposed against the Pasar Kendal facility, which impressively reduced 100% of its waste. The subsequent year, 2022, witnessed a dramatic shift in performance metrics: Jatirejo saw a significant uptick in its processing capacity to 50.00%, while Pasar Kendal experienced a reduction in efficiency, processing only 58.81% of its waste. This research accentuates the untapped potential for amplifying the capacity and effectiveness of composting as a waste management strategy in Kendal District, where a considerable volume of waste is composed of food remnants. The study proposes a series of solutions aimed at fortifying waste management capabilities, including infrastructure enhancement, comprehensive community education programs, and the enactment of more stringent governmental policies to facilitate improvement in waste processing rates.

Abstract

Crowds of flies will add to the burden of everyday life. Moreover, if the flies try to eat the fly, they will be caught in the trap placed in the container's open mouth. Therefore, the fly population at X Hospital, Tulung Agung, should be controlled to a non-hazardous extent. This study analyzes the practical design for catching flies in the temporary hospital waste collection area. Fly traps are designed based on design criteria. Where fly traps can be made of wood and wire mesh to form a cylinder, inside which the flytrap is placed cone-shaped wire mesh. The fly trap, which has a length of 165 cm, a width of 180 cm, and a height of 30 cm, will be applied in a closed container with a capacity of 6 m3 and dimensions of 3.3 meters in length, 1.8 meters in width and 1.2 meters in height. This eco-friendly fly trap is made using perforated anti-mosquito wire mesh and arranged on top of the container. At the same time, the flies obtained can be used according to the needs that will be used.

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

SARS-CoV-2 terus menginfeksi manusia dan menyebabkan kematian dengan jumlah yang tidak sedikit. SARS-CoV-2 dapat terdeteksi di saluran pernapasan, sampel darah, urine, feses, dan lainnya. Tujuan dari karya tulis ini adalah untuk mengetahui potensi penularan virus SARS-CoV-2 dari hasil analisis data literatur yang membahas potensi transmisi virus SARS-CoV-2 melalui feses manusia yang terkontaminasi serta mengetahui kondisi sanitasi di Indonesia selama pandemi Covid-19 terhadap kesehatan masyarakat. Metode yang digunakan adalah penelitian kualitatif dengan mengumpulkan data-data yang didapat dari jurnal, berita media massa, dan lainnya. Berdasarkan hasil penelitian yang dilakukan oleh peneliti di Cina dan data literatur, SARS-CoV-2 berpotensi dapat menular melalui feses manusia yang terjadi pada sejumlah pasien. Tidak hanya feses, tetapi pada urine juga terdapat sampel positif RNA SARS-CoV-2. Penularan tersebut bisa melalui jalur transmisi fecal-oral, tetapi perlu diperhatikan bahwa bisa berasal dari aerosol toilet. Kegiatan BABS di Indonesia masih dalam nilai 10,40% perlu digencarkan kembali agar target 0% BABS dapat tercapai. Tidak menutup kemungkinan bahwa penularan virus SARS-CoV-2 di Indonesia ke depannya dapat melalui feses dan air limbah. Oleh karena itu, dibutuhkan penelitian lebih lanjut yang dilakukan secara eksperimen di Indonesia sendiri karena sampai saat ini masih belum ditemukan kasus terkait penularan virus SARS-CoV-2 melaui feses.
