Abstract

The pulp industry is one of the sectors contributing to climate change, especially through greenhouse gas (GHG) emissions from wastewater treatment. This study aims to estimate the GHG emissions from the aerobic wastewater treatment applied by PT X using the IPCC method and to calculate the potential emission reduction by implementing anaerobic treatment. The results show that the COD concentration of the pulp industry effluent ranges from 500 to 600 mg/L. GHG emissions in the form of CH₄ are considered to be zero since the aerobic process does not produce CH₄, while CO₂ emissions from electricity consumption for the activated sludge aerator are 9.48 tons of CO₂/day. The implementation of anaerobic treatment is proposed as a solution to reduce GHG emissions by reducing electricity consumption and sludge production. Anaerobic treatment also has the potential to produce biogas, which can be used as an energy source for pulp production activities. The potential electrical energy from biogas utilization is estimated to be between 14.88 and 24.34 MWh, which is significant in reducing dependence on non-renewable energy sources while also reducing GHG and air pollutant emissions.

Abstract

Surabaya is the second largest city in Indonesia which is densely populated. The need for fresh water for the population of Surabaya is 4.61 m3/second, where many still use groundwater as a source of clean water. In this research, groundwater feasibility test will be carried out using 6 parameters at 31 points in the city of Surabaya. The water quality parameters to be tested are turbidity, temperature, pH, hardness (CaCO3), E. coli bacteria, and Dissolved Oxygen. The method used in the classification of ground water feasibility is the Mamdani method because it has a broad field coverage and is easily understood by humans. The results showed that the average quality of groundwater in the city of Surabaya was: turbidity 2.34 NTU, temperature 28.6 oC, pH 7.4, hardness (CaCO3) 349.67 mg/liter, and E. coli bacteria 0,13 CFU/100 ml, and DO 1.93 mg/l. The results of the evaluation of the feasibility of groundwater are compared with water quality parameters for hygiene and sanitation purposed based on PerMenKes No. 32 of 2017, all parameters have met the quality standards and are suitable as a source of clean water except for the parameter of E. coli bacteria. Based on the modeling using Fuzzy Mamdani type, there are ten sampling points that have groundwater that is not suitable as a source of clean water. Management recommendations for the protection of groundwater resources in the city of Surabaya for the community and for decision making by the government are disinfection using chlorine.

Abstract

Domestic wastewater management in Sawahlunto City is done by local system. About 75.5% of the houses use septic tanks, 4.1% are discharged into drainage channels, 4.5% are discharged into rivers, 15.9% have unknown location of domestic waste disposal. This study used primary data obtained from distribution of questionnaires to 100 respondents, interviews with stakeholders and field observations. Secondary data was obtained from related agencies. Evaluation of existing conditions through 5 aspects and determination of development strategy through SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) and business model selection using business model canvas. The result was an average desludging production rate of 0.4 liters/person/day. About 64% of the respondents stated that they have never emptied their septic tanks and 56% of the respondents did not know about Integrated Pond Treatment (IPLT). The SWOT analysis shows that the project is in quadrant II, which means that the development strategy includes drafting regulations on domestic wastewater management, transferring the authority of desludging management to the PUPR office, continuous dissemination of information, and collaboration with the private sector in the dissemination of CSR (Corporate Social Responsibility). Based on the assessment of the business model canvas, the business model for the short term is co-composting and the business model for the long term is scheduled desludging management. Another alternative is to use fecal sludge as briquettes that can be used as a substitute fuel for coal in Sawahlunto City.

Abstract

Greenhouse gas (GHG) emissions are the primary driver of climate change and have become a significant concern in recent decades due to their increasing atmospheric concentration. This study aims to systematically review research trends on GHG emissions over the past 20 years using bibliometric analysis. A total of 1,035 articles were analyzed through VOSviewer to map knowledge structure, research dynamics, and emerging topics. The results show that GHG emission research is divided into six main clusters: (1) gas emissions, (2) industrial and waste management, (3) air quality and human health, (4) bioenergy and energy systems, (5) food production, and (6) global climate change mitigation. Research trends indicate a shift from sectoral studies, particularly agriculture and livestock production (2005–2016), to a more integrated and systemic approach involving energy systems, air quality, and human health (2020–2024). The density visualization highlights “gas emission” as the most frequent and central keyword. Moreover, keywords such as "Municipal Solid Waste Treatment," "Energy Production," and "Domestic GHG Mitigation" have emerged as future research hotspots. This study provides a comprehensive overview of GHG emission research developments and offers valuable insights for identifying future research directions and supporting GHG mitigation strategies.

Abstract

Making fertilizer from goat dung usually requires additional materials such as fermenters, water, and dry leaves, as well as tools such as hoes, plastic sheeting, buckets, tarpaulins, and pestles. The process of making manure by farmers in Ngadirejo village, Kromengan district, takes quite a long time because the destruction of dry goat dung is still done manually by pounding. This study aims to design a goat dung crusher machine to optimize the destruction process. The method used to design this machine is Quality Function Deployment (QFD), which is an approach that focuses on meeting the needs of the users, in this case goat farmers. Through a questionnaire, the design attributes desired by the user are identified and translated into technical design responses. The next step is to create a design visualization and a machine prototype. The advantages of using the QFD method compared to previous methods are its ease of use, as well as increased efficiency and ergonomics compared to manual methods. This manure crusher machine is not only more efficient in terms of time and cost, but also provides comfort and safety for operators when using it. The following results were obtained from the calculations and planning in "Design of Goat Manure Smoothing Tool Using the Quality Function Deployment (QFD) Method": From five experiments conducted, the maximum force to crush goat dung was 4.6 kgf and power of 3.95HP, obtaining a torque value of 8437.5 kgf.mm, obtaining a shaft diameter of 17mm, obtaining a force on the pin of 2652.5N.

Abstract

The prolonged drought and declining water quality that struck Garut Regency in 2024 caused serious problems in the supply of clean water, exacerbated by the continuously declining water quality, thus requiring strategic steps in water resource management. This research focuses on the planning of a water treatment plant (WTP) in Garut Kota subdistrict, the area with the largest population in Garut Regency. This research aims to plan a WTP. The raw water source used is from Cimanuk River with a discharge of 313 l/second. The method used begins with an analysis of the river water characteristics based on a comparison of the river water quality with the water quality standards set by the Minister of Health Regulation No. 2 of 2023, and to determine the projection of clean water demand, a 10-year population projection is calculated. The water quality of the Cimanuk River shows that the parameters of BOD and fecal coliform exceed the standard quality standards, so a water treatment process with a series of units is needed, starting from the raw water intake, through coagulation, flocculation, sedimentation, filtration, to the final stage of disinfection. The maximum water demand is 164 l/s in 2034. The treatment results include BOD of 1.59 mg/L and Fecal Coliform of 0.0178 CFU/100ml; these values indicate that the treatment results meet the quality standards.
