Abstract

The increasing population has led to higher consumption and the generation of household waste, particularly in the Bandung Raya area. The Legok Nangka Final Processing and Disposal Site (TPPAS) is planned as a solution for regional waste management after the Sarimukti landfill has completed its operational period. The service area of the Legok Nangka TPPAS follows the service area of the Sarimukti landfill, which includes the City of Bandung, the City of Cimahi, Bandung Regency, and West Bandung Regency. Given the existing conditions of the Legok Nangka TPPAS location, which is relatively far from the city and regency centers that generate waste, an alternative Intermediate Transfer Station (SPA) is needed. This facility can reduce waste volume while increasing waste density by three times. This research focuses on analyzing alternative locations for the Intermediate Transfer Station (SPA) in the City of Bandung to enhance the efficiency of waste transportation to the Legok Nangka TPPAS using Geographic Information System (GIS) based on Network Analysis. The results of this study indicate that the implementation of the Intermediate Transfer Station (SPA) significantly improves waste transportation efficiency. With a capacity of 500 tons per day, the SPA reduces the volume of waste directly sent to the Legok Nangka TPPAS by 26%. The distance and travel time for trucks are reduced by 23.97% for pool 1 and 25.91% for pool 2, respectively. Efficiency is also evident in the reduction of fuel consumption and carbon emissions, with decreases of up to 25.91%. The average number of trips required is 83 trips per day, indicating a reduction in long-distance travel to the TPPAS. These findings underscore the importance of the SPA in sustainable waste management in the City of Bandung.

Abstract

Tempat Pengolahan dan Pemrosesan Akhir Sampah Regional Lulut Nambo (TPPAS Nambo) direncanakan oleh Pemerintah Provinsi Jawa Barat untuk melayani 4 wilayah yaitu Kota Depok, Kota Bogor, Kabupaten Bogor, dan Kota Tangerang Selatan. Tujuan penelitian adalah menganalisis berbagai alternatif skenario kebijakan guna mengoptimalkan pelayanan pengelolaan sampah di 4 wilayah tersebut dan mengetahui pengaruhnya terhadap sampah yang terangkut ke TPPAS Nambo dengan pendekatan model sistem dinamik. Simulasi dilakukan terhadap 4 skenario yaitu business as usual (BAU), optimalisasi fasilitas pengolahan sampah eksisting, implementasi rencana induk pengelolaan sampah daerah (masterplan), dan implementasi Kebijakan Strategi Daerah (Jakstrada) pengelolaan sampah. Dari hasil simulasi mulai tahun 2020 hingga 2045, didapat bahwa keempat kota di atas tidak dapat hanya mengandalkan keberadaan TPPAS Nambo yang memiliki keterbatasan kapasitas pengolahan, sehingga kehadiran Tempat Pemrosesan Akhir (TPA) di masing-masing kota/kabupaten masih tetap diperlukan. Dari hasil simulasi didapat bahwa Skenario Jakstrada merupakan skenario yang paling optimal adalah bila mempertimbangkan jumlah timbulan sampah yang harus dikelola, biaya pengangkutan, kebutuhan lahan untuk TPA dan emisi lingkungan, walaupun mensyaratkan adanya kebutuhan fasilitas penanganan sampah di sumber yang lebih besar. Perkiraan biaya pengolahan sampah dari Skenario Jakstrada untuk masing-masing Kota Depok, Kota Bogor, Kabupaten Bogor dan Kota Tangerang Selatan adalah sebesar Rp 297.584/ton, Rp 543.345/ton, Rp 285.532/ton, dan Rp 305.902/ton. Dari validasi model terbukti bahwa sistem dinamik dapat diaplikasikan untuk menganalisis keterkaitan berbagai macam faktor yang perlu dipertimbangkan dalam proses perencanaan untuk mencapai pengelolaan sampah yang berkelanjutan.

Abstract

Background: One of the main environmental challenges in Coal-Fired Power Plant (CFPP) operations is the large amount of Fly Ash and Bottom Ash (FABA) produced, which creates significant waste management issues. Reducing FABA production through biomass co-firing has become a potential solution, yet its effectiveness in actual operations remains underexplored. Asam Asam Power Plant Unit 1–4, with a capacity of 4 × 65 MW in South Kalimantan, is one of the power plants that utilize sawdust biomass in its operations.Aims: This study aims to analyze the effect of coal and biomass consumption on FABA generation during 2022, 2023, and 2024.Methods: The method employed is multiple linear regression using Minitab version 21.4.1 software, with coal consumption (X1) and biomass consumption (X2) as independent variables and FABA generation (Y) as the dependent variable.Result: The results show that coal consumption has a positive relationship with FABA generation, while biomass consumption shows a negative relationship. ANOVA test results indicate that only coal consumption significantly affects FABA generation. A notable decrease in FABA production in 2024 signifies an increase in biomass utilization in the fuel mixture, highlighting its potential in reducing solid waste generation from CFPP operations. A simulation involving three biomass-coal blending scenarios demonstrated that incorporating 20% biomass into the fuel mix can reduce FABA generation by up to 27.79%.

Abstract

Waste management in Indonesia, especially in big cities, faces a big challenge as the volume of waste continues to increase every year. One of the technologies used to address this problem is incineration, which is the process of burning waste to reduce its volume and generate energy. However, this process produces residues in the form of fly ash and bottom ash (FABA), which contain harmful heavy metals such as Zn, Cu, Cr, Ba, and Ni. If not managed properly, these residues can pollute the environment because they are difficult to decompose and are potentially harmful to human health and ecosystems. This study aims to analyze the physical and chemical properties of FABA to determine its potential utilization. The results showed that fly ash has a finer particle size with a higher density than bottom ash which has coarser and larger particles. Based on ASTM C618 standard, FABA belongs to class C category, which shows SiO2 + Al2O3 + Fe2O3 > 50% content > 50%, and CaO content > 15%. FABA has the potential to be utilized in construction, where fly ash can be used as a partial substitute for cement, while bottom ash can replace sand. The utilization of FABA enables the production of environmentally friendly construction materials, such as rosters, bricks, and paving blocks, which are the result of recycling residues. Thus, the utilization of FABA also reduces the amount of residue generated by the incineration process and reduces dependence on natural raw materials, supporting the creation of a more sustainable construction industry.

Abstract

E-commerce activities have shown significant growth, especially during the Coronavirus Disease (Covid-19) pandemic, driving an increase in packaging waste generated by consumers from their online purchases. Similar to other cities, Yogyakarta City has waste management facilities at source, but the existence of this infrastructure has not significant reduced the amount of waste transported to the Piyungan landfill. This study aimed to predict consumer behavior and measure their willingness to participate in packaging waste management through the Theory of Planned Behaviour (TPB) model. Data was collected through structured questionnaires distributed to 111 respondents in 14 subdistricts in Yogyakarta city which were then analyzed using Partial Least Square-Structural Equation Modeling (PLS-SEM). The results showed that knowledge, perceived behavioral control, and convenience had a significant effect, while subjective norms and attitudes had a insignificant effect on the willingness of consumers participation in packaging waste management.
