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

Indonesia, as one of the most populous countries in the world, requires clean water sources. Industrial waste that is improperly discharged pollutes water bodies with hazardous metals. Adsorption is one of the effective methods for reducing the concentration of harmful metals in water. This study utilized fulvic acid extracted from goat manure compost and combined it with chitosan and magnetite as an adsorbent material for Ni(II). The FTIR results for the magnetite-fulvic acid-chitosan composite showed a peak at 1627 cm⁻¹, indicating the presence of aromatic C=C, aromatic ring -OH, and quinone C=O groups, which confirm the binding of fulvic acid. BET analysis was performed on magnetite and magnetite-fulvic acid-chitosan, and the pore volume and pore size were found to be 0.177488 cm³/g and 6.5394 nm, respectively. The composite exhibited magnetic behavior due to the attraction between the magnetite-fulvic acid-chitosan and an external magnet. Adsorption tests using isotherm and kinetic models revealed that Ni(II) adsorption followed a multilayer mechanism and pseudo-second-order kinetics, with a b value of 121.68 mg/g and an experimental qe of 6.28 × 10⁻⁵ mol/g. This shows that the magnetite-fulvic acid-chitosan composite is a promising, sustainable, and magnetically separable adsorbent for the effective removal of nickel ions from contaminated water.

Abstract

The development of stealth technology in modern defense systems demands superior radar absorbing material (RAM) innovation. This study aims to synthesize and characterize Fe₃O₄/ZnO modified carbon-based RAM composites in a polypyrrole (PPy) matrix using graphite oxide (GiO). The composites were synthesized via a modified Hummer method as well as a one-pot technique, and characterized using FTIR, XRD, SEM-EDX, and VNA. The FTIR characterization results showed that the C=C peak decreased in intensity after the oxidation process, indicating the breaking of the aromatic double bond and the formation of new functional groups such as C–O and C=O. This change was detected in both pGiO and kGiO samples. XRD data showed a shift in the main peaks to 2θ = 11.25° and 42.20° for pGiO and 2θ = 11.56° and 42.40° for GiO-k, respectively. This shift indicates the formation of a more amorphous graphite oxide structure compared to the original graphite.The results show that GiO/Fe₃O₄/ZnO has the highest reflection loss value of -9.20 dB at 10.91 GHz (GiO-p/Fe₃O₄/ZnO 66%-PPy) with an absorption value of 88.03% and rGO/Fe₃O₄/ZnO/PPy the highest RL value reached -7.51 dB at 11.57 GHz (rGO-k/Fe₃O₄/ZnO 66%-PPy) with an absorption value of 82.21%. This research proves that Fe3O4/ZnO modified carbon-based composites in a polypyrrole matrix have high potential as an efficient radar absorbing material and can support the needs of domestic defense technology.

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.
