Abstract

The utilization of biomass and polyethylene terephthalate (PET) waste as raw material for refuse-derived fuel (RDF) has been studied. However, physical such as density and hardness are still not widely used. This study aimed to determine the relationship between variations in the composition of PET and physical garden waste density and hardness on the quality of the caloric value of RDF. Density measurements were carried out with the Ultrapyc 1200e instrument. While for hardness, using the Shore D method. The Shore D Hardness test is a standardized test that involves evaluating the amount of depth that may be penetrated by a certain indentation. The lowest density is RDF pellets for food waste at 1,537 kg/m3 and consists of RDF pellets for plastic waste at 2,560 kg/m3. In line with the density, the hardness value increases with the addition of the PET composition. The density and hardness values in the RDF mixture show a simultaneous relationship to the heating value. The highest caloric value achieved is the use of 100% PET as pellets which can reach 5765 kcal/kg.

Abstract

the Punge Intersection is one of the four-armed unsignalized intersections in Banda Aceh City without traffic regulations such as traffic lights, roundabouts, or other warning signs. This condition is very troublesome for road users, especially during peak hours. It is considered necessary to evaluate the performance of the intersection along with alternative treatments that produce the best performance to meet the standards. Most of the previous studies relied heavily on tailor-made simulation tools to evaluate control algorithms, but the use of simulation platforms to make system comparisons through modeling is still very rare, especially in Indonesia. Analysis and modeling at the Punge Intersection using the MKJI method and PTV VISSIM 10.00-02 (VISSIM) software. Traffic volume data (plan), road geometric, and environmental conditions are needed in data processing operations using VISSIM. Three modeling scenarios were carried out with the implementation of a one-way road for arm A in the entry direction, installation of a traffic signaling tool, called APILL, roundabout planning and widening of each arm. A roundabout planning simulation with type R10-22 with widening on each road section can make the Punge Intersection with the best LOS and meet the best service levels.

Abstract

global warming and environmental issues are being caused by the overuse of fossil fuels and increased industrialization around the world, which has resulted in the production of greenhouse gases. As a result, it's crucial to reach net-zero carbon emissions. By balancing the total quantity of carbon dioxide or other greenhouse gas emissions over a specific period and taking actions that are ecologically responsible, net zero carbon emissions can be accomplished. For environmental sustainability to be successful, it must be able to influence people's attitudes and behavior toward the environment. To understand NGOs' obligations in supporting net-zero carbon emissions, this paper presents a methodical debate utilizing NGOs as case studies. The method is employed in this work by reviewing the body of primary and secondary research on the study issue. This essay initially lists different environmental NGOs organizations before categorizing and outlining some of the significant GHGs reduction initiatives made by these organizations. This essay also addresses key issues that must be addressed upon to achieve the best outcomes. This report gives a broad overview of the synergizing domains that NGOs around the globe work in to assist improvement environmental security.

Abstract

Population growth has led to increased runoff and wastewater flowing into drainage channels. This study, therefore, aims to evaluate the drainage capacity of selected channels in Medan City and whether they can still serve the community in the next 10, 20 and 30 years. The observed channel starts from Taduan Street No. 1 to Taduan Street No. 153, with a length of 1,000 m. This evaluation considers population growth, the volume of domestic wastewater, the volume of runoff, the generation of sediment in channels, and evapotranspiration as part of the water cycle. Monthly maximum rainfall data from 2012-2021 from the BMKG Sampali Medan and population data along Taduan are used in the review in this article. Based on the investigation, it is known that the volume of drainage on Taduan Street is no longer able to serve the community even for 2032. It is necessary to review and redesign the dimensions to ensure that wastewater from household activities and runoff does not have a negative impact, especially during the rainy season. With as many as 48 injection wells and the Watershed expansion, it is expected to reduce inundation. Keywords:   Drainage channel, Domestic wastewater, Evaluation,  Medan, Rainwater

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

This study aims to analyse the causes of delays in the implementation of construction projects caused by management (owners/consultants) and production (contractors). The research sample consists of 56 respondents who are directly involved in the implementation of construction projects (owners, consultants, contractors, field supervisors, and estimators). The quantitative data analysis technique used was descriptive analysis technique, while the qualitative data obtained by interviewing 5 construction project experts was analysed by qualitative descriptive method. To analyse the causes of delays in project implementation, an analysis technique using the Relative Importance Index (RII) formula was used with a reference value of RII> 0.710. The results showed that 1) the average RII on management factors was 0.895> 0.710. This means that management factors (owner/consultant) can cause delays in the implementation of construction projects; 2) the average RII on production factors is 0.917> 0.710. This means that production factors (contractors) can cause delays in the implementation of construction projects. This means that production factors (contractors) can cause delays in the implementation of construction projects. This research is directly useful for construction service providers and contributes to the development of Project / Construction Management science.

Abstract

According to Presidential Regulation No. 35 of 2018, which focuses on accelerating the development of waste-to-energy projects, Denpasar City in Bali has been identified as one of the key Indonesian cities for implementing these projects. The daily waste generation in Denpasar City is estimated at 750 tons. The city's sanitation strategy outlines that 20% of this waste will be reduced at its source, while the remaining 80% is managed at the final treatment site. This study employs the Life Cycle Analysis (LCA) approach to evaluate the environmental impacts of traditional landfilling and various thermal waste treatment methods. The findings reveal that gasification (Scenario 2) has the lowest Global Warming Potential (GWP), with 779,759 kg CO2 equivalent emitted, indicating its superiority in reducing greenhouse gases. In contrast, landfilling (Scenario 1) is the least favorable, with a GWP of 2,885,770 kg CO2 equivalent and a significant cancer risk due to hexavalent chromium emissions estimated at 1,634,050 kg equivalent. These results underscore the health and environmental hazards of landfilling. Further, the study delves into each treatment scenario's impact on acidification, eutrophication, global warming potential, and photochemical oxidation.

Abstract

One of the most widely used fuels is coal, where the South Sumatra region is an area with coal potential whose production is still being increased. On the other hand, there are negative impacts caused by coal exploration activities, one of which is mining runoff, commonly called acid mine drainage. Acid mine drainage has a low pH and contains inorganic constituents such as iron and manganese. Therefore, proper and optimum information processing is needed to support environmentally friendly mining management. In contrast, alternative materials such as blast furnace slag, wood ash, fly ash, cement kiln dust, and construction waste are being used. These materials are effective against AMD, at a relatively low cost, and outperform traditional neutralizers. However, comparing them with conventional agents is challenging due to limited data and experimental variation. In this study, the objectives to be achieved are 1) to determine the quality conditions of AMW at the study location, 2) to determine the effectiveness of the use of chemical and alternative compound neutralization agents in the processing process, and 3) to provide recommendations for the dosage, type of neutralization agent, and the most optimum time in AMW processing. The AMW obtained is then subjected to laboratory analysis related to quality, including TSS, pH, Fe, and Mn parameters. In addition, conventional and alternative neutralization agents are also prepared and then used to process AMW. Then, experiments were carried out on variations in the type of neutralization agent, the dosage of neutralization agent use, and the contact time between the neutralization agent and AMW. Experimental results have shown that these materials, mainly pond ash and concrete sludge, can effectively neutralize pH and reduce Mn concentrations by up to 83.26% and 79.12%, respectively. Similarly, Fe concentrations can be reduced by up to 80.76% and 74.05% using pond ash and concrete sludge, respectively. While these results are promising, future research should focus on characterizing the generated sludge to confirm the adsorption of ferrous and manganese ions onto the surface of the alternative neutralizers.
