One of the competitiveness parameters of tourist destinations is the cleanliness index. Labuan Bajo as a super-priority tourist destination has a very serious municipal solid waste (MSW) problem. Waste generation in Labuan Bajo and Komodo National Park in 2020 reached 14.06 tons/day and is projected to be 15.51 tons/day in 2023. The main sources of...

A new building filling materials (NBFM) using phosphogypsum and municipal solid waste incineration (MSWI) fly ash is prepared in this paper. The effects of MSWI fly ash dosage and MSWI fly ash water washing pretreatment on mechanical properties, setting time, metal leaching, hydration products and microstructure of NBFM are analyzed by a range of e...
Municipal solid waste incinerator (MSWI) fly ash poses intricate compositional challenges and potential environmental hazards. Effective management of such hazardous waste is imperative to mitigate the release of toxic compounds into the environment. Solidification/stabilization (S/S) processes have emerged as a viable strategy to transform MSWI fl...
Municipal solid waste incineration fly ash (MSWIFA) can be reused as a positive additive to strengthen soft soil. In this study, MSWIFA was initially used as a supplementary solidification material in combination with ordinary Portland cement to prepare fly ash cement-stabilized soil (FACS) with silty sand and silty clay, respectively. The ratio of...
Municipal solid waste incineration (MSWI) fly ash is considered hazardous waste due to heavy metals. Their improper management/disposal is lethal for both humans and animals. This paper aims to explore the gelling properties of fly ash, activated by adding different alkali activators, i.e., Na2SiO3, NaOH, KOH, Na2SiO3:NaOH (1:1, g/g), and Na2SiO3:K...
This study investigates the possibility of using municipal solid waste incineration fly ash as a supplementary cementitious material to replace part of the clinker in cement. Life cycle assessment has shown that the partial replacement of clinker with blast furnace slag (CEM III) reduces cement’s global warming potential by ~30%, while replacing cl...

The incineration of municipal solid waste (MSW) effectively reduces waste and has a side product, such as electricity. The waste-to-energy (WTE) power plant in Bantargebang is the first national pilot plant facility in Indonesia using moving grate incinerator (MGI) technology, with a 100 tons/day design capacity and a maximum design of electricity power output of 750 kW. The main challenge of WTE in Indonesia is high moisture content (MC) and unsorted waste. Hence, it is imperative to include the pre-treatment facility through waste drying and sorting. In this work, over 241 working days from January to December 2022, approximately 15,451.35 tons of MSW (averaging 70.55 tons/day) have been incinerated at an average temperature of 613.8 o C. Waste pre-treatment alleviates waste MC from 20.13% to 8.59%. This process achieves a significant waste mass reduction of 81.52-96.50%. In addition, the system generates superheated steam at maximum values of 5000 kg/h, 340 o C, and 38-39 barA. The total electrical energy generated (956.04 MWh) is used to supply the electrical energy demand of the internal plant operation (1368.78 MWh). Moreover, the wastewater and flue gas in this WTE have successfully been processed by the pollution control systems to meet national standards. The fly and bottom ash from MSW incineration have proven harmless and suitable for construction material or cement admixture. This work conclusively shows that WTE Bantargebang provides positive implementation in almost all aspects, encompasses a significant amount of waste reduction, satisfying incineration performance, a significant amount of electricity generated, and the environmental performance does not harm the surroundings. Related to the performance deficiencies found is expected can be a valuable input for WTE development in Indonesia.

One of the factors for the competitiveness of tourist destinations is cleanliness, especially solid waste management. Toba Regency, as one of the buffer zones for the tourist destination of Lake Toba, cannot be separated from the challenge of reducing and handling solid waste generated by households, industry, and tourists. The amount of waste generated in Toba Regency in 2022 is 31,794 tons/year with a reduction rate of 0.94%, 37% dumped in landfill and 62% unmanaged. A simulation was carried out through data analysis from various planning documents, field observations, and interviews with stakeholders to get the best scenario for achieving the Jakstranas waste target in this study. Scenario 1 is by maximizing recycling through waste banks with a capacity of 10,074 tons/year or scenario 2 by composting food waste as much as 7,665 tons/year and recycling through waste banks at 2,317.75 tons/year. Scenario 1 is more likely to be implemented than scenario 2, considering the low compost market. If scenario 1 is implemented, the potential for creating a circular economy ranges from Rp. 19,654,374,000 to Rp. 22,354,206,000 annually. Salah satu faktor daya saing destinasi wisata adalah kebersihan, khususnya pengelolaan sampah. Kabupaten Toba sebagai salah satu wilayah penyangga destinasi wisata Danau Toba tidak lepas dari tantangan untuk mengurangi dan menangani sampah yang dihasilkan baik oleh rumah tangga, industri, maupun wisatawan. Jumlah timbulan sampah Kabupaten Toba tahun 2022 sebanyak 31.794 ton/tahun dengan tingkat pengurangan sebesar 0,94%, ditimbun di Tempat Pemrosesan Akhir (TPA) 37% dan tidak terkelola 62%. Melalui analisis data dari berbagai dokumen perencanaan, pengamatan lapangan dan wawancara dengan pemangku kepentingan dilakukan simulasi untuk mendapatkan skenario terbaik dalam mencapai target Jakstranas persampahan dalam studi ini. Skenario 1 dengan memaksimalkan daur ulang melalui bank sampah dengan kapasitas 10.074 ton/tahun atau skenario 2 dengan melakukan pengomposan sampah sisa makanan sebanyak 7.665 ton/tahun dan daur ulang melalui bank sampah 2.317,75 ton/tahun. Skenario 1 lebih mungkin dilaksanakan dibanding skenario 2 mengingat rendahnya pasar kompos. Jika skenario 1 terlaksana maka potensi terwujudnya ekonomi sirkuler berkisar antara Rp. 19.654.374.000 hingga Rp. 22.354.206.000 per tahun.
