Abstract

Indonesia’s coastal waters have great potential wealth in supporting human life and as an ecosystem for several species. However, this potential is eclipsed by heavy metal pollution caused by industry and domestic activities. The purpose of this study is to determine the concentrations of heavy metals mercury (Hg) and lead (Pb) in numerous species of mussels often found in Indonesian coastal waters. The research method used was systematic literature review. The results showed that coastal waters in several regions I Indonesia, especially in the provinces of Aceh, Central Java, Banten, West Java, East Java and Jakarta, have significant concentrations of heavy metals. Thirteen kinds of mussels were found to have heavy metal pollution. But the most heavily polluted with heavy metals were lead (Pb) and mercury (Hg) were green mussels (Perna viridis). The results demonstrated that many varieties of mussels have higher concentrations of the heavy metals lead (Pb) and mercury (Hg) than the maximum allowed by BPOM Regulation No. 9 of 2022.

Abstract

The rising levels of heavy metal pollution in water bodies present major environmental and public health issues. Conventional methods for remediation often come with high costs and produce secondary waste, which can pose additional environmental risks. As an alternative, chitosan—a natural, biopolymer derived from chitin—has gained attention as a promising biosorbent for heavy metal removal. Its advantages include biocompatibility, biodegradability, and a strong ability to bind metal ions effectively. This review explores chitosan’s capacity to adsorb various heavy metals and examines its practical applications in biosorption technology. Key factors that impact its adsorption efficiency, such as solution pH, metal concentration, and contact time, are discussed. Additionally, structural modifications to enhance chitosan’s performance, including cross-linking and nanoparticle incorporation, are analyzed to highlight improvements in adsorption efficiency. By assessing these elements, this review aims to offer a comprehensive perspective on the role of chitosan in environmental management, particularly for treating heavy metal contamination in wastewater. The findings underscore chitosan's potential as a sustainable solution in pollution control, emphasizing its advantages over traditional methods and its capacity to contribute to cleaner water resources.

Abstract

Indonesia is an archipelagic country with an ocean area wider than land. Indonesia's ocean areas contain many maritime activities, one of which is shipping and trade. This activity causes a lot of domestic and foreign transportation to pass through Indonesia's maritime areas. It is not uncommon for domestic and international sea transportation to discharge exhaust emissions from their fuel onto the sea surface, causing marine damage. This article was created with the aim of summarizing previous research to make it easier for readers and to find out the appropriate types of maritime chemical fuels, combustion and exhaust emissions, as well as reducing pollution from combustion. The review of studies uses a comparative approach, collecting sources from Google Scholar and PubMed databases, as well as national and international publications. The research results show that liquefied natural gas (LNG) and hydrogen are good candidates to replace chemical fuels because they are both sulfur-free.

Abstract

Waste is one of the major problems in terms of preserving the natural environment for humans. When waste is produced in large quantities, improper management will endanger human health and the environment. Making Eco-Enzyme (EE) products from waste, especially organic waste from homes, is one possible answer. Since Eco-Enzyme is made by fermenting organic waste using brown sugar as a substrate, it can be produced on a small scale. The aim of this project is to find out the advantages of producing Eco-Enzyme products from household organic waste, especially fruit and vegetable waste. This experiment uses the method of literature review and simple experimentation. The result of this experiment is an Eco-Enzyme product that is used as a disinfectant, a mixture of floor cleaning detergents, a pesticide residue cleaner, a descaler and a decrease in car radiator temperature, a hand-sanitizer (hand sanitizer) and also a skin wound medicine.

Abstract

Meningkatnya konsumerisme dan terbatasnya kesadaran masyarakat terhadap penggunaan plastik telah mengakibatkan penumpukan sampah plastik yang signifikan di wilayah pesisir Kepulauan Riau. Contoh nyata adalah tumpukan sampah setinggi 3,5 meter di Pantai Senggarang, dan produksi sampah harian Batam yang mencapai 1.200 ton, dengan kapasitas TPA yang terbatas. Penelitian ini melakukan analisis bibliometrik, yang bertujuan untuk mengidentifikasi tren publikasi dan pola kutipan dalam penelitian bioplastik dari tahun 2020 hingga 2025 untuk memahami dinamika pertumbuhan dan dampak ilmiah bidang ini. Analisis bibliometrik terhadap 990 publikasi bioplastik (2020–2025) dengan 49.801 kutipan dan h-indeks 105 menunjukkan evolusi penelitian dari karakterisasi bahan dasar seperti pati dan selulosa hingga eksplorasi bahan baku inovatif termasuk limbah makanan dan mikroalga. Analisis kepadatan mengungkap bahwa konsep "bioplastik" memiliki intensitas penelitian tertinggi, dengan kaitan signifikan dengan plastik, bio, PLA, dan biopolimer, serta aplikasi praktis seperti pengemasan makanan dan sifat mekanis. Pola temporal menunjukkan bahwa konsep produksi bioplastik, mikroalga, dan degradasi muncul sebagai area penelitian yang signifikan pada tahun 2022. Hal ini menandai pergeseran paradigma dalam penelitian menuju proses produksi berkelanjutan dan peningkatan biodegradabilitas sebagai solusi untuk krisis plastik konvensional.

Abstract

This research is part of a strategic research program in environmental technology and renewable energy focused on climate change mitigation. Organic waste management through composting technology is a strategic approach to reduce waste generation and the potential for methane (CH₄) emissions from anaerobic decomposition. This study aimed to analyze the effectiveness of local microorganism (MOL) bioactivators, namely rice MOL (P1), banana mob MOL (P2), and fruit MOL (P3), in accelerating composting, compared to controls (without the addition of MOL). The results showed that fruit MOL (P3) is the most effective bioactivator for accelerating decomposition and improving compost quality. This treatment achieves the fastest maturity in 40 days with the lowest C/N ratio and the highest macronutrient content (Nitrogen (N), Phosphorus (P), Potassium (K)) compared to other treatments. These findings confirm that the application of local bioactivators can significantly improve the efficiency of campus organic waste management and support environmental sustainability.
