Abstract

Every human being always produces waste in his life, be it organic waste or inorganic waste. With the increasing number of people in the world, of course, the amount of waste produced will increase. To overcome these problems, we need a technology that can utilize waste to be used as a source of renewable energy, as was done by PLTSa Benowo in the city of Surabaya. At PLTSa Benowo, the use of waste to be used as a renewable energy source is carried out in two ways, namely Landfill Gas Recovery (LFG) and Gasification. The two processes will produce gas which will be used to generate 11 MW of electrical energy. Utilization of waste to be used as a source of electrical energy provides many benefits for humans, besides being able to overcome the problem of urban waste which is increasingly piling up, it can also provide electricity supply for PLN. The author uses descriptive methods through a qualitative approach, this research intends to understand what phenomena are experienced by the research subjects. The results of the research are expected to provide additional knowledge about PLTSa Benowo which is located in the city of Surabaya.

Abstract

The management of used medical mask waste has become a significant issue due to the increased volume of waste during and after the pandemic. Medical mask waste contains cellulose compounds that can be converted into derivatives such as glucose, which are then processed into bioethanol as an alternative energy source. This study aims to hydrolyse medical mask waste using cellulase enzymes from Aspergillus Niger to produce glucose. The cellulase enzyme composition was varied (5 ml, 15 ml, and 25 ml) to determine the optimal hydrolysis conditions. The glucose produced was measured using DNS reagent assay with spectrophotometry at a wavelength of 540 nm. The highest amount of glucose was obtained under optimal conditions with 25 ml of cellulase enzyme after 48 hours of hydrolysis, amounting to 88.16 ppm. Subsequently, the glucose from hydrolysis was fermented using Saccharomyces cerevisiae, and the fermentation product was analysed for ethanol concentration using GC-FID. The products of fermentation ware 0.017% ethanol concentration from mask waste fermentation. Hydrolysis is an environmentally friendly alternative solution for handling mask waste.

Abstract

As the world’s largest nickel producer, Indonesia faces critical challenges in decarbonizing its nickel smelting sector while maintaining economic growth. This study addresses the lack of integrated assessments of carbon pricing impacts and green finance mechanisms in Indonesia’s nickel industry, using exclusively secondary data from government reports (BPS, MEMR), global databases (IEA, Global Carbon Atlas), and policy documents. A gate-to-gate Life Cycle Assessment (ISO 14044) reveals that Indonesian nickel smelters emit 14.8 tons CO₂-eq per ton of product (IEA, 2023), 25% higher than the global average. Economic modeling, based on nickel price trends (LME, 2020–2023) and carbon tax scenarios, indicates that a $40/ton CO₂ tax would raise production costs by 15%, reducing export competitiveness by 6.2% under current market conditions. Policy analysis highlights the feasibility of green bonds and fiscal incentives for renewable energy adoption, referencing successful cases in the Philippines (RE Law, 2022). These findings provide a data-driven framework for aligning Indonesia’s nickel industry with its 2060 net-zero target, emphasizing the role of secondary data in shaping low-carbon transitions for resource-rich economies.

Abstract

The global energy crisis and increasing demand for low-carbon energy sources have positioned biomass as a strategic alternative in the transition to renewable energy. Forestry waste such as sawdust and wood chips have great potential to be converted into energy, but their utilization in Indonesia is still not optimal despite their abundant availability. Indonesia produces approximately 146.7 million tons of biomass per year with an estimated energy potential of 470 GJ/year, indicating significant opportunities for energy diversification. This article examines the potential of forestry waste biomass as an energy source, developments in conversion technology, and economic and sustainability challenges. A comparative analysis of the Fujino & Hashimoto (2023) study shows that biomass can provide local economic benefits, but its effectiveness in reducing emissions still depends on supporting technology and policies. The results of the study emphasize the need to develop high-efficiency biomass generation technology and a regulatory framework that encourages the sustainable use of waste so that biomass can play a role as a pillar of national renewable energy.

Abstract

Energy security is a strategic element in supporting sustainable development and national security, particularly in Indonesia's outermost islands. Wetar Island in Southwest Maluku Regency faces serious challenges in the form of high dependence on fuel oil and limited energy distribution systems. This study aims to conduct an in-depth analysis of the challenges of distribution and dependence on BBM and their impact on the energy security of Wetar Island. The study uses a qualitative approach with a case study method through analysis of policy documents, energy institution reports, and related scientific studies. The results of the study show that the dominance of BBM, logistical obstacles due to geographical conditions, and high energy costs have led to low resilience in the local energy system. In addition, the limited use of renewable energy has increased the region's energy vulnerability. This study emphasises the need for energy diversification, strengthening of local infrastructure, and integration of central and regional policies in order to achieve sustainable energy security for Wetar Island.

Abstract

Magnetite nanoparticles (Fe₃O₄) possess unique magnetic properties and are widely applied in various fields such as biomedical technology, environmental remediation, and material separation. This study reports the synthesis of Fe₃O₄ using the co-precipitation method under varying conditions of temperature, reaction time, and atmospheric exposure (open vs. closed system). Ferric and ferrous salts were reacted with ammonium hydroxide under controlled heating at 70°C and 80°C for 60 minutes. The synthesized materials were evaluated through visual color inspection, qualitative magnetic response, yield efficiency, and magnetic load-bearing capacity. The results showed that a closed system at 80°C produced the most optimal Fe₃O₄, indicated by a deep black color, strong magnetic attraction (149.86 mN), and a yield of 92.5%. Comparatively, open systems led to partial oxidation of Fe², resulting in less magnetic phases like maghemite or hematite. The findings confirm that controlling synthesis parameters, especially atmospheric exposure and temperature, significantly influences the purity, particle uniformity, and magnetic strength of Fe₃O₄ nanoparticles, highlighting the importance of optimized synthesis for practical applications.

Abstract

Heavy metal contamination in water is one of the most critical environmental issues, posing direct threats to human health and ecosystems. Various methods have been developed to address this problem; however, adsorption remains the most effective technique due to its simplicity, low cost, and regenerability. In this context, ferrite based materials (MFe2O4) offer great potential as heavy metal adsorbents owing to their combined advantages of magnetic properties, chemical stability, large surface area, and easy separation under an external magnetic field. This review paper provides a systematic comparison of various types of metal ferrites (Ni, Mn, Co, Zn, Mg, Cu, and Nd) applied for the removal of heavy metal ions from water. The comparison covers their crystal structures, morphology, surface area, magnetic properties, adsorption capacity, as well as the isotherm models and kinetics underlying the adsorption process. The findings show that each type of ferrite possesses specific advantages and limitations. NiFe2O4 exhibits high structural stability, MgFe2O4 demonstrates high adsorption capacity but is susceptible to dissolution under acidic conditions, CuFe2O4 exhibits strong chemical affinity, and NdFe2O4 shows potential selectivity toward specific ions. Meanwhile, MnFe2O4 and CoFe2O4, particularly in composite forms such as MnFe2O4/biochar and CoFe2O4/FAU, stand out with adsorption capacities exceeding 400 mg/g, sufficient magnetic properties, and easy magnetic separation, making them the most promising candidates for water treatment applications. This paper provides a comprehensive understanding of the structure property function relationship of metal ferrites as selective, stable, and efficient adsorbent materials for heavy metal remediation in aquatic environments.

Abstract

Fossil fuels—coal, oil, and natural gas—remain central to global energy despite environmental concerns. This study examines the logistics of transporting these fuels, each with unique challenges. Coal relies on bulk rail and ship transport, raising pollution concerns. Oil uses pipelines and tankers, with risks like spills. Natural gas, especially LNG, requires complex infrastructure for liquefaction, shipping, and regasification. Safety is a major issue due to hazards like explosions and spills, prompting industry reliance on technology and regulations. Environmental impacts include emissions, ecosystem damage, and methane leaks. The paper calls for improved efficiency, safety, and sustainability in logistics. Through case studies, it highlights innovations and best practices to mitigate risks and enhance performance. As the world shifts toward cleaner energy, fossil fuel logistics must evolve to meet environmental standards and societal expectations.

Abstract

Tourism destinations in Indonesia generate food waste in significant number and contribute to 39.78% of total national food waste (FW). However, characterization data for bioprocess applications and evaluations of waste processing remains limited. This study aimed to quantify and characterize food waste from tourism destinations to assess baseline conditions for circular economy and bioprocess implementation. FW was systematically collected and analysed from Jatim Park 2 tourism facilities over Oktober 2024 to January 2025. Food waste generation rates, physical composition, and chemical properties were determined. Existing waste management framework assessed using observational method and stakeholder interviews. Average of 89.2kg/day food waste was generated from 1 main restaurant and 16 food seller in Jatim Park 2 area and predicted to increase up to 121.5kg/day in weekend or holiday. Average moisture content was 72.71%, total solid of 27.29%, and C/N ratio of 46.40. Existing waste processing was limited to collect and transport from waste collection point to waste storage point only. Furthermore, external contractors were contracted to provide waste and FW disposal services. Unfortunately, their partners do not have sufficient disposal service capacity to handle the volume of waste and FW produced. This inadequacy results in the accumulation of waste and FW to a significant volume. In general, the results indicate that tourism FW represent significant untapped resources. The baseline data provides foundation for suitable FW management strategies. Implementation of circular economy could transform FW streams into valuable products contributing to sustainable tourism development.
