Abstract

This study used red mud as an adsorbent for biogas purification. However, red mud had to undergo dealumination and calcination processes before being used as an adsorbent. Several acids, including 1 M HCl and 1M H2SO4, were employed in the red mud dealumination process, which was then analysed by XRF and GSA instruments. The results show that the best type of acid for the dealumination process was HCl with a Si/Al ratio, total pore volume, surface area and pore radius of 1.697; 67,081 m2/g; 0.1624 cm3/g; 48.4242 Å. The biogas purification process was carried out using red mud adsorbent dealuminated with HCl by varying the length of the adsorbent column, such as 10, 20 and 30 cm, and the contact time of 5, 10, 15 and 20 min. The optimum column length variation was 30 cm. The results obtained for this variation were a decrease in CO2 content of 292742.30 ppm with an efficiency of 19.08%. The increase in CH4 was 378232.69 ppm with a percentage increase of 240.28%.

Abstract

Kapur Village is located in Sungai Raya District, Kubu Raya Regency. The existing condition of waste management has not been implemented properly due to the lack of waste management facilities, namely temporary waste disposal and other communal waste containers, so efforts are needed to handle the waste management system, by planning temporary waste disposal 3R plus. The aim of planning is to know, analyse existing condition of management waste, generation size, density, waste composition and planning the 3R temporary waste disposal design. The research method is sampling generation, density and composition of waste according to SNI-19-3964-1994, conducting interviews and questionnaires to obtain selected locations. The resulting waste generation is 0.35 kg/person/day. The density of domestic source waste is 142.09 kg/m3, while the largest density of non-domestic source waste is produced from restaurants at 113.32 kg/m3. The composition of domestic waste is dominated by organic waste with a percentage of 49.3%, while non-domestic waste is dominated by paper waste with a percentage of 30.60%. This 3R plus temporary waste disposal planning requires land of 1,112.3 m2. The planned waste management is is processing organic waste into composting using the hollow brick method, while inorganic waste in the form of plastics and bottles is processed into handicraft products.

Abstract

Massive industrial and urban development can cause changes in the quality of river water, one of which is the Garang Watershed, located in Central Java Province. This river is situated in Kendal Regency (upper and middle) and Semarang City (middle and lower). This research examined the Garang River's water quality conditions, divided into four sub-basins: Garang Hilir, Garang Hulu, Kreo and Kripik. The parameter assessed in this research is TSS, TDS, Total Phosphate, Nitrate, and Total Coliform Parameters with a total of ten sampling location points were determined based on several criteria using GPS and the SNI 6989.57:2008 sampling method. TSS and TDS concentrations in March-April were observed to be high, especially at sampling point 10. In contrast, total phosphate concentrations were elevated at sampling points 2, 3, and 9; Nitrate values were observed to be high at sampling point 3 in March and sampling point 5 in April; Total coliforms were high at sampling points 1, 3, and 4, all of these is possibly due to domestic waste and the use of fertilizer by agricultural activities. This sampling quality assessment shows a close relationship between human activities and agricultural activities in river water quality, especially in the Garang River.

Abstract

Leachate resulting from the decomposition of organic waste is still a challenging problem, especially in landfill management.  Constructed wetlands (CW) are effective, economical, and environmentally friendly options to treat landfill leachate. Biochar added into CW as a pollutant adsorbent in leachate treatment.  This study aimed to determine the effectiveness of sub-surface flow CW amended with biochar in reducing leachate pollutants. Biochar was synthesized from crumb rubber scrap waste using pyrolysis. The variation biochar in CW i.e. CW0 without biochar as a control system, CW1 10% biochar, CW2 20% biochar, and CW3 30% biochar.  Leachate samples flowed into each CW reactor for 10 days of retention time.  The scanning electron showed that the biochar pores ranged from 5-10 կm, containing elements of C, O, Ca, N, Mg, Al, Si, and Fe.  Some elements have greater cumulative mass and atomic percentage values i.e. C 34.51%, O 26.54%, and Ca 21.85%.  The result of CW treatment showed that the CW system was able to remove 76-88% BOD5, 70-87% COD, and 67-81% TSS.  The addition of biochar in CW increased pollutant removal by 7-14%, showing that biochar is able to increase pollutant adsorption in wastewater and improve CW performance. Furthermore, converting organic waste into biochar is highly recommended as a sustainable way to generate useful resources.

Abstract

The snack food industry is one of the major industries in Indonesia that has various types of products, one of which is snacks (cookies), which are widely consumed as snacks. This study aims to determine the characteristics of wastewater from the snack food industry (cookies). The research was conducted in three factories located in Bandung Regency, Sumedang Regency and Majalengka Regency. Primary data were collected from wastewater samples collected monthly for laboratory testing. Data analysis used descriptive statistical analysis of average concentration of wastewater parameters using Microsoft Excel software and SPSS 25 software. The main parameters of wastewater from the snack food industry (cookies) are pH, TSS, BOD, COD, ammonia, total nitrogen, and MBAS. From the comparison of the resulting BOD, COD, TSS, ammonia, and total nitrogen pollutant loads, the largest load trends occur in Factory B, Factory C, and Factory A. Failure to properly treat these crucial wastewater parameters can pose risks to the environment and surrounding communities. Thus, these vital parameters form the basis for selecting wastewater treatment plant technology to fulfil environmental standards. WWTP process recommendations that can be used are grease trap, surge tank, dissolved air flotation (DAF), anaerobic system, aerobic system, secondary clarifier, and post-treatment.

Abstract

The development of ecotourism in Goa Rangko, Labuan Bajo, West Manggarai Regency, East Nusa Tenggara, has increased waste generation, resulting in environmental degradation and negative impacts on the tourism industry. To address this issue and achieve sustainable tourism, this study aims to investigate the current waste management system in Goa Rangko and propose an optimized solution. The research was conducted through direct field observations and the collection of secondary data from literature and government documents. Waste characterization studies were undertaken to determine waste generation and composition. Based on the findings, a Material Recovery Facility (MRF) was recommended for waste management. The MRF would encompass a source-to-final processing system, ensuring efficient waste handling. Any residue from the process would be appropriately disposed of in the landfill. In addition to the MRF, the study proposes the involvement of the local community, along with education and awareness-raising programs. These initiatives aim to foster a sense of responsibility among the residents and tourists in managing waste sustainably. Moreover, the study suggests implementing an ecotourism certification program to support sustainable tourism development in Goa Rangko.

Abstract

Transmigration is one of the government programs that aim to create a new growth center by establishing an activity center through the development of basic business patterns. Development of the main business pattern is carried out through the management of land resources for agriculture. Improper management of land resources can lead to a decrease in environmental quality. Therefore, it is necessary to know the potential carrying capacity of ecosystem service to plan agricultural development. Parameters are used to analyze the carrying capacity of ecosystem services as provisioning based on environmental services for water and food provisioning. The environmental service assessment method for water and food provisioning is calculated using weighting and scoring. The total value of the carrying capacity of ecosystem services as provisioning is obtained from the calculation of the two parameters using the Simple Additive Weighting method. The results of the analysis show that the value of the carrying capacity of ecosystem service as provisioning is classified as very low. This indicates that the capability of the land for agricultural development is very low. Agricultural development requires conservation actions to increase the carrying capacity of ecosystem service. Recommendations for conservation actions are carried out through land use arrangements.
