Abstract

Matoa fruit is abundant in Papua and has not been optimally utilised. Matoa fruit consists of ash approximately 3.74%. The high ash and silica content make it highly suitable as a raw material for zeolite production. Zeolite can be used as a zeolite material to adsorb heavy metal Cu(II). Heavy metal pollution continues to increase with industrial growth. Heavy metals can harm human health. Innovation must continue addressing heavy metal pollution, such as Cu(II), to produce more efficient, cost-effective, and environmentally friendly technologies. This study aims to determine the ability of matoa fruit zeolite to adsorb heavy metal Cu(II). The characterization of zeolite was done using XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscope). The synthesis process involved preparing sodium aluminate and sodium silicate solutions, followed by controlled crystallisation at 105°C for 24 hours. The zeolites were tested for adsorption with the independent variable being zeolite mass, while the dependent variables were contact time of 48 hours and stirring time of 4 hours. SEM analysis confirmed the cubic morphological characteristics of matoa fruit zeolite, classifying the product as matoa fruit zeolite. The main findings of the study showed that matoa fruit zeolite can reduce Cu metal levels in sewage-polluted water with 88.85% adsorption at 0.5 g in 50 ml of test solution.

Abstract

Low-carbon aquaculture is increasingly recognized as a vital strategy to mitigate climate change, improve resource efficiency, and ensure sustainable food production. This systematic review, following the PRISMA 2020 protocol, analyzed 58 peer-reviewed studies selected from 312 published between 2020-2024, providing a transparent and replicable synthesis of the current evidence. Research is predominantly focused in Asia and Europe, regions where rapid aquaculture growth coincides with emerging climate policies. Key strategies for reducing environmental impacts include Integrated Multi-Trophic Aquaculture (IMTA), cultivation of low-trophic species such as seaweeds and filter feeders, and the restoration of coastal ecosystems, all of which enhance carbon sequestration, nutrient cycling, and ecosystem resilience. The review identifies the most commonly reported sustainability indicators as global warming potential (GWP), energy consumption, land use, nutrient loading, and eutrophication. Despite ongoing technological innovations, global aquaculture remains largely unsustainable with persistently low environmental performance. Barriers to improvement include incomplete carbon accounting, fragmented regulatory frameworks, and limited consumer awareness. Additionally, significant knowledge gaps in greenhouse gas emissions and carbon sequestration constrain robust life cycle assessments. Transitioning to low-carbon aquaculture requires not only technological innovation but also with stronger governance, ecosystem-based management, and integrated policy frameworks to enhance sustainability and climate resilience. This review underscores the urgency of coordinated action across research, industry, and policy sectors to optimize low-carbon strategies, address existing knowledge gaps, and support the development of sustainable aquaculture systems that are both environmentally responsible and economically viable.

Abstract

The high use of fossil fuels to the point of a spike, is a sign that fuel is needed by the community. Currently, alternative energy in the form of biodiesel has been developed as one solution to this problem. Biodiesel is a substitute for diesel fuel made from renewable sources such as vegetable oils or animal fats through a transesterification process, so that the fuel becomes more environmentally friendly. In this study, seeds from bintangur fruit (Calophyllum inoopyhllum) were used as biodiesel feedstock by going through a degumming process for oil separation and impurities, esterification to reduce free fatty acid (FFA) levels, transesterification to make biodiesel, and analysis of characteristics in the form of density, viscosity, FFA (free fatty acid) levels, and water content. Based on the results obtained, transesterification results 1 on Bintang Tanjung for density of 1.0898 gr/cm3, viscosity 0.575 mm2/s, moisture content 5.412%, and transesterification results 1 on Bintang Misool for density of 1.033 gr/cm3, viscosity 0.6381 mm2/s, moisture content 4.473%. And the results of transesterification 2 at Bintang Tanjung for density of 0.8837 gr/cm3, viscosity 8.99 mm2/s, FFA content 3.63%, moisture content 0.26%, and transesterification 2 results in Bintang Misool for density of 0.8416 gr/cm3, viscosity 8.99 mm2/s, FFA content 7%, moisture content 8.79%. Thus, it can be concluded that neither Tanjung star nor Misool can be used as biodiesel.

Abstract

Corrosion is one of the main causes of material degradation in piping systems, which has a direct impact on safety and operational efficiency. The corrosion process, influenced by the environment, material type, and operational conditions, leads to the thinning of pipe walls over time. Therefore, evaluation of the corrosion rate is crucial in determining the remaining service life of pipes, allowing for mitigation measures to be planned before system failure occurs. This study aims to analyze the corrosion rate using a quantitative approach based on inspection data and to predict the remaining service life using a time-based degradation method. The pipe material examined in this study is API 5L Grade B with a maximum carbon content of 0.30%. The types of corrosion occurring in the internal piping of natural gas are erosion corrosion and crevice corrosion. The reduction of pipe thickness by 0.43 mm is caused by the natural gas content from the gas flow activities that contain hydrocarbon and non-hydrocarbon compounds. The corrosion rate of 0.165 mm/year results in a remaining service life of the pipe being 45 years. This corrosion rate shows a relatively good resistance to corrosion. The results of this study are expected to provide technical recommendations for the sustainable management of pipeline assets.
