Published: December 2024

Abstract
The environment has become a crucial issue in addressing the climate crisis, with universities plaing a key role by positioning students as agents of change. However, the success of university environmental programs is often limited by a lack of student engagement. This study explores the relationship between environmental knowledge and behavior, mediated by environmental attitudes and environmental intelligence. Using an exploratory quantitative approach and the Theory of Planned Behavior, 385 students from the top five universities in Central Java were surveyed. The results show that environmental attitudes significantly mediate the relationship between knowledge and behavior, with a mediationeffect size of 0.45 (p < 0.01). Additionally, environmental intelligence mediates the relationship between knowledge and attitudes (0.35, p < 0.01). These findings underscore the role of attitudes and intelligence in shaping students’ environmental behavior, highlighting the need for holistic and sustainable environmental education programs in universities to foster positive environmental actions.

Abstract
The pharmaceutical industry’s fabrication of pharmaceutical products releases byproducts that have the potential to negatively impact the environment. Indicators of contaminants include characteristics such as COD, BOD, TOC, pH, and turbidity that are within acceptable standards of excellence. The objective of this study was to look at fluctuations in the concentrations of pharmaceutical wastewater substances parameters before and following treatment with the ozonation method, as well as to assess the ozonation procedure’s performance on pharmaceutical wastewater contaminants parameters. The ozonation methods, which altered the O3 retention period, served as the independent variable in this study. The dependent variables applied were pH optimalization, and the removal efficiency of turbidity, BOD, COD, and TOC. Controlling variables involve the starting pollutant concentration, pressure and temperature levels, and equipment conditions. To determine the ideal time variation for the ozonation process, many variations will be evaluated. However, several parameters (e.g. pH, BOD, and TOC) were not reducing with the designed time variations. Nevertheless, this approach was effective in reducing turbidity levels by 48.5% and COD levels by 55.4% over 15 minutes.

Abstract
PT Pupuk Iskandar Muda, a company operating in the fertilizer sector, produces waste in its production process, so a waste reduction program is needed. The Low-Temperature Shift Converter (LTS) catalyst used in the fertilizer production process at the Ammonia Factory produces catalyst waste classified as hazardous and toxic. Each LTS catalyst has a lifespan of four years before requiring replacement with a new catalyst. Regular replacement of LTS catalysts leads to a substantial hazardous waste generation of 22.25 tons per year, necessitating special handling to prevent environmental pollution. An innovation was carried out using the method of changing the Standard Operating Procedure by changing the operating conditions, which involved adjusting the operating temperature of the LTS catalyst from 195 to 210°C to regulate the flow of boiler feed water supplied to the Heat Exchanger. This innovation aims to reduce the waste of hazardous and toxic materials and the cost of procuring the catalyst. This initiative succeeded in extending the life of the LTS catalyst to nine years (2012-2021). As a result, there was a significant reduction in catalyst waste generation during 2012-2021, namely 12.32 tons per year, accompanied by annual cost savings of IDR 1,531,200,000.

Published: December 2024

Abstract
Ruminants such as cattle and goats are significant contributors to greenhouse gas emissions, particularly methane (CH4) and nitrous oxide (N2O). Methane is produced through enteric fermentation in ruminants and their manure management practices, while nitrous oxide emissions stem from the utilization of animal manure. At the Singosari Artificial Insemination Centre (BBIB), there are around 180 male cattle and 140 goats, this study was conducted to assess methane and nitrous oxide emissions from these animals and arrange the strategies for emission reduction. The Intergovernmental Panel on Climate Change (IPCC) methodology was implemented to calculate emissions, whereas the methane levels was determined by using local factors (Tier-2) and nitrous oxide levels using default for Asian countries. TOPSIS analysis was chosen to identify the key strategies for reducing greenhouse gas emissions, considering technical, cost, and environmental criteria. Three strategies for carbon emission reduction are community-based livestock biogas initiatives (BATAMAS), organic fertilizer processing units (UPPO), improved manure storage systems, and the provision of high-quality animal feed. Findings revealed methane emissions of 286.10 tonnes CO2-eq/year or 1.59 tonnes Co2-eq/head/year, mainly from enteric fermentation, and nitrous oxide emissions totaling 2.75 tonnes CO2-eq/year or 0.015 tonnes CO2-eq/head/year from direct livestock manure management.

Abstract
The seawater desalination technology, named WEFO (Water with Electrolysis, Filtration, and Ozonation), holds significant potential for addressing clean water scarcity in coastal areas. This study employs Life Cycle Assessment (LCA) to evaluate the environmental impact of producing the WEFO device. The LCA results indicate notable environmental impacts, mostly attributable to using stainless steel and aluminum alloy. Stainless steel contributes 72.81% to abiotic depletion, 85.54% to acidification, 47.64% to eutrophication, 79.87% to freshwater ecotoxicity, 81.05% to terrestrial ecotoxicity, and 81.40% to photochemical oxidation. Meanwhile, aluminum alloy is responsible for 57.48% of global warming and 64.10% of ozone layer depletion. The manufacturing process of these materials emits pollutants that damage air and water quality and contributes to climate change and ecosystem disturbance. To mitigate these impacts, it is advisable to decrease the utilization of materials with significant environmental consequences in components such as wheel plates, faucets, and frames, replacing them with more environmentally friendly alternatives. Implementing these alternatives is expected to make WEFO technology more sustainable and provide an environmentally friendly solution to clean water scarcity in coastal areas while preserving human and ecosystem health.

Published: December 2024

Abstract
The building sector is a significant global energy consumer, requiring strategic efforts for efficiency improvements. This research focuses on residential homes in satellite cities around Jakarta, where many developer-built houses offer potential for energy-efficient design. Modeling energy consumption helps identify opportunities for implementing energy-saving measures when standards are exceeded. This research takes a case study of three house built by a private developer in the South Tangerang area. The research was conducted using simulation and experimental methods using the Sefaira application from Trimble SketchUp. The location, geometric data, materials, and building form were analyzed to obtain an accurate model of energy consumption levels. All three types of houses fall into the very efficient category based on SNI standards, ranging from 4.17 kWh/m2/month to 9.13 kWh/m2/month. However, compared to the EUI standard in the Sefaira application based on “The 2030 Challenge”, the EUI values for each building still exceed the expected standard of 25 kWh/m2/year.

Abstract
Wood pellets are gaining a lot of attention as a sustainable fuel alternative due to the growing need for renewable energy sources. Understanding the physical properties of wood pellets is crucial for optimizing their production and performance. In this study, the mechanical durability of Dipterocarpus sp. sawdust pellets was enhanced with the application of starch and carboxymethylcellulose. The internal structure of the pellet, including the distribution of pores, the integrity of the pellet matrix, and the existence of imperfections, can be recognised by high-resolution, in-depth examinations of the surface morphology of the pellet provided by Scanning Electron Microscopy (SEM) imaging. The results indicate that different binders and their concentrations have different morphological structures of pellets. Nonetheless, there is a tendency for the five pellet types to have similar densities. Of the five variations tested, the 100% starch binding material could produce pellets with the best physical properties.

Abstract
Tourism activities that focus on the exploration of (local) food, known as gastronomy tourism, are increasingly popular. Salatiga is designated as a gastronomic city in Indonesia. The rapid growth of tourism has impacted the environment, making it important to evaluate the ecological footprint of tourism. The objectives of this study are: 1) to analyze the resource consumption per tourist in terms of carbon footprint generated from gastronomy tourism and 2) to study the contribution of ecological footprint of gastronomy tourists in Salatiga. The resulting carbon footprint was calculated through carbon dioxide (CO2) emissions generated from transportation, food and waste generation, and accommodation, as a guide to calculate the ecological footprint of gastronomy tourism in Salatiga. Using random sampling, a constructed questionnaire was collected from 139 tourists in Salatiga. The results showed that the carbon footprint of gastronomy tourism activities contributed up to 6 million kgCO2e per year, equivalent to 1,256.3 gha. The footprint is still appropriate, but could pose a threat to ecological sustainability. These findings provide important insights for policy makers and tourism industry players in formulating more sustainable strategies to manage gastronomy tourism in Salatiga.

Published: December 2024

Abstract
Amide bonds are prevalent in peptides, synthetic polymers, insecticides, and pharmaceuticals. These bonds play a critical role in medicinal chemistry due to their stability, ability to interact with biological targets, and flexibility in designing bioactive compounds. Many methods have been devised to date for the synthesis of amides, however the majority of them rely on coupling agents and an excess of bases to neutralize the acid produced during the reaction. These techniques have low atom economy and generate a lot of waste, making them unfriendly to the environment. Greener chemical methods have been developed as a result of the growing worldwide awareness of environmental issues and the drive towards sustainability. In this context, new approaches are being developed based on the concepts of green and sustainable chemistry, particularly through emerging research utilizing organic electrosynthesis. This review aims to demonstrate the application of sustainable amide electrosynthesis as a green chemistry pathway for the development of future pharmaceuticals.

Abstract
The world population is increasing, which has implications for increasing food needs. Food crop cultivation faces problems, namely pest attacks. Pest attacks will cause a decrease in agricultural productivity. The use of synthetic insecticides has a negative impact on the environment and human health. Therefore, it is important for further research to produce safer and more effective insecticides from natural ingredients. Based on a literature review, the essential oil content of Baeckea frutescens L has the potential to be a bioinsecticide. Therefore, in this study a hydrosol formulation was carried out with essential oil from B frutescens L as an insecticide control. This research tested the efficacy of the formulation against Spodoptera sp pests on mustard greens. It was found that a formulation with the addition of 30% essential oil to the hydrosol achieved 100% mortality against Spodoptera Sp pests. This formulation has great potential to be developed as a safe and environmentally friendly insecticide.
