Abstract

Degenerative diseases such as stroke and cancer arise due to oxidative stress by a large number of reactive oxygen species (ROS) in the body. Free radical scavenging (antioxidant) compounds are needed to neutralize the ROS. The natural antioxidant potential of mangrove species Sonneratia caseolaris has been widely explored. However, its extraction is usually carried out with polar solvents such as methanol. Besides being more toxic than ethanol, methanol can cause blindness and death when inhaled in large quantities. Additionally, Indonesia, as the country with the largest Muslim population, requires the use of halal products for food and cosmetics. This study aims to analyze the scavenging activities of S. caseolaris with methanol and distilled water as the polar solvents for extraction. Antioxidant activity was tested with the free radical assay method of DPPH (2,2-diphenyl-1-picrylhydrazyl radicals). The test results were calculated as the IC50 value, a concentration capable of reducing free radicals by 50%. The antioxidant activity test showed that the IC50 values of methanol and distilled water were 18.9 ppm and 36 ppm, respectively. Therefore, both are considered very strong antioxidants. It indicates that distilled water is an acceptable substitute for methanol in the extraction process. Keywords: antioxidant, extraction, mangrove, solvent, Sonneratia.

Abstract

This study aims to determine the effect of using natural deep eutectic solvent in extracting compounds from young and old leaves of Avicennia marina on the antibacterial activity through in vitro and in silico. The research method used was experimental with different molar ratios of solvent components: citric acid and glucose (1:1, 2:1, 3:1, 4:1 v/v). In vitro, the paper-disk method was employed to assess percent inhibition, and in silico, peptide deformylase (ID 6JFQ) was the target of the investigation. The best treatment results for testing the antibacterial activity of A. marina leaves extracts that were extracted using natural deep eutectic solvent against S. aureus and E. coli was citric acid and glucose (molar ratio 4:1). The inhibition zone by old leaves extracts was 27.47 and 37.73 mm, and by young leaves extracts were 28.69 and 30.99 mm. Then, phytochemical compound analysis was done using liquid chromatography-mass spectrometry, and six phytochemical compounds were obtained. The docking results showed that the diosmetin 7-O-β-D-glucuronide has the best binding affinity (−9.4 kcal/mol) towards the peptide deformylase. Purification must be done to obtain pure compounds from crude extracts of A. marina leaves.

Abstract

Pasuruan City, located in East Java, plays a significant role in the fisheries sector, contributing to industrial and trade activities. However, production declines, influenced by poor water quality and flooding, threatens the sustainability of jelak milkfish farming. This study aims to analyze the status and sustainability index of the milkfish farming business using the MDS-Raps method, which evaluates it based on five dimensions: ecology, economy, social aspects, technology, and institutions. The respondents included 41 farmers from four fish farming groups (Pokdakan). The results shows that the business is fairly sustainable, with a multidimensional index of 51.99, meaning it can be continued and developed but does still has room for improvements. The sustainability status by dimension is as follows: ecological (65.24, fairly sustainable), economic (37.39, less sustainable), social (78.72, very sustainable), technological (27.40, less sustainable), and institutional (51.18, fairly sustainable). The study also proposes seven strategies to enhance sustainability and identifies a link between the MDS analysis and SWOT strategies in managing milkfish farming. Each SWOT strategy offers insights for improving the value of individual dimensions in the MDS framework.

Abstract

Municipal solid waste (MSW) generation contributes to methane emission, formed during anaerobic decomposition of organic. The MSW reduction can be forced into an integrated solid waste management site through 3R paradigm built in each municipal level area. This is because methane has a relatively short atmospheric lifetime of about 12 years compared to CO2. This means that reducing methane can quickly impact slowing global warming in the short term. This study aimed to achieve maximum results in reduction methane emission generated from an urban area through 3R waste treatment facility with measurable evaluation in 3 scenarios. The method used to gather the data analysis is Minitab 22 software, which forecasts an approach through trend method analysis, moving average, single exponential smoothing, and double exponential smoothing model to obtain the best-fit model for scenario analysis. The result showed that trend analysis has a high accuracy category with the smallest error (<10%: strong accuracy) in BaU, scenario 1, scenario 2, and scenario 3 with the MAPE value 0.002071 (0.2%), MAD value 0.00, and MSD value 0.00. Meanwhile, scenario 3 could decrease the amount of waste sent to landfills 188.03 tons/year in 2024 and 203.53 tons/year in 2033. Whilst, it could reduce methane up to 0.829126 tons-CO2-eq /year in 2024 and 0.897479 tons-CO2-eq /year in 2033 from total waste in Janti or 8-10% from the total methane emissions in Jabon landfill (65683,8 tons-CO2-eq /year). It concluded that optimizing the activities of 3R waste management facility units in each area, particularly in Sidoarjo, can significantly reduce the effect of methane emissions that arise in landfills.

Abstract

The Metro River flows from upstream to downstream across East Java to support several human activities such as household, toilets, or agriculture. The utilization of water rivers must be balanced with water quality monitoring so that the quality of the water can be monitored. This study aims to analyze the abundance of microplastic in the Metro River. Moreover, the water parameters (pH, dissolved oxygen, temperature, flow velocity) were also measured. Sampling was carried out at three different stations, namely station 1 representing the agricultural activity area, station 2 representing the household activity area, and station 3 representing industrial activity. This study shows the abundance of microplastics in biofilm matrices and surrounding river water. The types of the microplastics are fibers, fragments, and films. The total abundances of microplastics in river water ranged from 0.8 - 1.61 particle.mL-1, while the biofilm matrices ranged from 7.4 to 9.5 particle.gram-1. The results of water quality parameters at all stations are still relatively good compared to quality standards. To the best of our knowledge, this study was the first study that reports the microplastics in the water of and inside biofilm formed on Metro River.

Abstract

Waste management in Muncar, Banyuwangi, East Java, faces critical challenges, with 40 tons of waste generated daily and only 11% of the population accessing waste collection services by 2018. PROJECT STOP was introduced to address these issues through an integrated waste management strategy that combines governance, facility development, behavior change initiatives, and partnerships with local government. This study used a variety of methods, such as collecting data on waste production, judging the effectiveness of waste processing facilities, and polling people in the community to find out what role institutional frameworks like village-owned businesses (BUMDes) and community-based organizations (KSM) play in promoting sustainable waste governance. The results showed that PROJECT STOP used two types of governance models: the Village Waste Operator Model, which cut costs by 29% (from USD 31.2 to USD 22.2 per ton) by getting people to work together, and the Joint Village Model, which centralized operations across five villages and kept costs at USD 25 per ton while making them more efficient. Collectively, the initiative managed 16,876 tons of waste, served 90,773 residents, and improved operational efficiency through resource sharing and institutional support. The lessons learned from PROJECT STOP show how important collaborative governance is for building waste management systems that are both long-lasting and scalable. Additionally, they offer a model for addressing issues comparable to those in other regions of Indonesia. Keywords: waste management, collaborative, community waste governance, institutional framework

Abstract

In 2020, Banyuwangi Regency generated 852 tons of waste daily, with 78% (approximately 664 tons) unmanaged, primarily from rural areas (83%). By 2021, about 77% of this waste will continue to pollute the environment, and projections for 2040 indicate annual waste could exceed 500,000 tons, posing a risk of 385,000 tons of environmental pollution without enhanced management strategies. Private sector involvement is mandated by Banyuwangi Regulation No. 6/2022, requiring companies to implement waste reduction initiatives and develop comprehensive waste management plans, necessitating monitoring and evaluation for effective policy implementation. This paper investigates the Banyuwangi Government's capacity to implement waste reduction roadmaps by producers in the Regency.  The study uses a qualitative descriptive method. Data collected consist of secondary and primary data. The study consists of two analyses. The first analysis was conducted on sample documents of waste reduction roadmap developed by producers to assess the document’s quality. The second analysis is to assess the policy capacity of Banyuwangi Regency Environmental Agency to understand which area of competence still needs to be strengthened. The study emphasizes the need for producers to register with the Environmental Agency, ensuring compliance and oversight of waste reduction initiatives. The research highlights the significance of adaptability in the political landscape, particularly in modifying strategies to correspond with shifts in political leadership and development objectives. It also confronts the local government's limited financial capacity. The paper provides initial insights regarding the Banyuwangi local government's capacity to effectively enact these policies. Keywords: waste reduction, policy implementation, government policy capacity

Abstract

Siomay, a popular Indonesian snack traditionally made with high-fat chicken or beef fillings, can be made healthier by using mackerel fish instead. This modification, combined with the addition of potato starch, aims to improve the nutritional profile of siomay while maintaining its appeal to consumers, as mackerel is both tasty and nutritious.  This study aims to improve the nutritional profile and consumer acceptance of siomay filling through the integration of mackerel meat and potato starch. Data were analyzed using a Completely Randomized Factorial Design with two factors (mackerel meat and potato starch) mixed in different proportions in the siomay filling dough. Parameters tested included nutritional composition (protein, fat, carbohydrate, fiber, and mineral), physicochemical properties (texture, color, and aroma), and consumer acceptance test using a hedonic scale. The results showed that the most preferred treatment was K2D2 (14g mackerel meat and 20g potato starch), which was 5.6±1.5. The nutritional content of the siomay filling preferred by the panelists increased (water 29.07 g, protein 12.89 g, fat 3.65 g, ash 3.41 g, sugar 1.35 mg, vitamin B1 0.26 mg). However, the carbohydrate content decreased to 50.98 g, compared to the content of siomay filling without the addition of yellow potato starch (56, 74 g). This study shows that mackerel flour and potato starch can potentially be used to improve the nutritional profile and consumer acceptance of siomay filling.

Abstract

The Leachate Treatment Plant (LTP) at Supit Urang Landfill produces a by-product of dewatered sludge that has not been utilized optimally and according to its potential. Sludge is a highly organic material that agriculture can reuse as a fertilizer or soil conditioning agent. However, its potential heavy metals possess environmental risks. Currently, sludge from the dewatering process is disposed of in landfills. Sludge left open without further handling will potentially be a source of environmental pollution that will cause unpleasant odors. This study aims to identify how to utilize sludge as raw material for compost mixtures. The approach applied in this research was quantitative with an experimental design. Sludge was mixed with ready-made compost and EM4 solution. Composting is carried out with three different ratios of sludge and compost, which consist of (w/w) 1:1 (M1), 1:2 (M2), and 1:3 (M3). The addition of EM4 solution (10% of the mixture weight) was used to enhance the efficiency of the composting process. The result revealed that after 21 days, the quality of co-composting sludge and ready-made compost met the requirements of SNI 19-7030-2004. The best results were obtained in mixture M3 (C-Org = 17.92%, Ntotal = 1.71%, Ptotal = 0.80%, Ktotal = 1.33%, C/N-ratio = 10.38, Cd = 2.47 mg.kg-1, Hg = 0.0 mg.kg-1). These findings suggest that sludge has the potential to be used as raw material for compost mixtures.
