Advances in science and technology are faced with a number of challenges, one of which is preserving the environment which is faced with the use of synthetic materials. Synthetic materials are basically materials that cannot be decomposed naturally and pollute the environment. Therefore, a number of research and developments have been carried out in utilizing more environmentally friendly materials through the manufacture of biocomposites. However, the use of biocomposites has not been able to replace the use of synthetic materials as a whole, due to the weak bonding of the fiber-matrix interface (adhesion between fiber and matrix) in biocomposites. One effort that can be made to increase fiber-matrix interfacial bonding in biocomposites is through modification of natural fibers using NaOH. A number of studies have been carried out using NaOH to modify the fiber-matrix surface. The results obtained through a number of studies state that each natural fiber has a different response to NaOH concentration, so that each natural fiber requires a certain concentration to increase the bond between the fiber-matrix interface in biocomposites.

The lack of human awareness of environmental problems and limited natural resources is a challenge that needs to be corrected for the survival of future generations. Raising awareness through environmental literacy habits needs to be instilled from basic education, this is done because instilling character values will be more effective given from an early age. Infographic media is a way to convey overall information clearly, complexly and quickly. With the aim of knowing the use of infographics regarding the problem of preserving natural resources as an effort to increase environmental literacy in elementary school students. The type of research used is a qualitative approach with a literature study method. Infographics are an interesting medium for increasing environmental literacy in students. Students can be guided to collect and analyze problems in the surrounding environment, analyze the impacts that will occur, and find solutions to overcome these problems which are outlined in the form of infographics. By instilling environmental literacy in children from an early age, it is possible for students to have an attitude of caring about the environment.

The exploration of policies for the conservation of marine biodiversity in the management of natural resources (SDA) in Indonesia emphasizes the urgency of preserving marine biodiversity in the world's largest archipelagic country. Challenges such as illegal fishing, environmental degradation, and a lack of institutional coordination take center stage. With the aim of identifying barriers and opportunities for policy implementation, this study analyzes models of natural resource management using a qualitative approach through literature review. The study focuses on theories of conservation, natural resource management, and international collaboration. The findings highlight the complexity of policy issues and practices in managing marine natural resources, including an evaluation of the "Community-Based Folley Sea Sasi Management" and "Blue Economy Implementation" models. The recommendations put forward involve enhancing supervision, strengthening international collaboration, and implementing advanced technologies. The implications of these findings are expected to support the formulation of more effective policies and efforts to conserve marine biodiversity in Indonesia.

Environmental care activities carried out in the form of reforestation in Negeri Kilang are also an implementation of the Pattimura University KKN student program, the first batch of Class L, aimed at increasing the knowledge of the Negeri Kilang community about the role and function of plants, as well as creating the character of the Negeri Kilang community who care about the environment. Carrying out activities is a form of assistance in the field as well as outreach to village communities regarding reforestation efforts as a form of protecting and preserving the environment. The results of this tree planting activity are the planting of clove, mahogany, ironwood and durian tree seedlings in reforestation locations and in hamlets/community gardens which can be utilized according to their intended purpose to make land use more efficient, apart from optimizing ecological functions, as well as providing economic value for the people of the Negeri Kilang.

This research will focus on the evaluation of socio-economic development policies in Sape District, Bima Regency, with the aim of understanding the extent to which development efforts have achieved their goals. This study employs a qualitative descriptive method and a Literature Review. The research location includes the Bima Regency Development Planning Agency, the Department of Tourism, the Department of Marine and Fisheries, the Department of Environment, and the Department of Social Affairs of Bima Regency. The research findings indicate that Sape District has significant economic potential in the fisheries and agriculture sectors, but it still faces a considerable level of poverty, especially among coastal households. The economic empowerment of coastal communities needs to be enhanced through skills training programs, financial assistance for business capital, and improved access to business loans. Furthermore, a specific focus on generating employment opportunities, particularly for young people, is essential. Poor infrastructure and limited accessibility pose significant obstacles to economic development. Investments in infrastructure improvement, such as roads and ports, are required to enhance mobility and market access. Sustainable natural resource management is vital for preserving the potential of fisheries and agriculture in the area. Strict law enforcement against illegal fishing practices and educational efforts to promote sustainable fishing practices are necessary. Climate change impacts, including rising sea levels and extreme weather conditions, affect the region. Therefore, strategies for climate change adaptation and mitigation need to be developed. The evaluation of socio-economic development policies indicates that assistance programs have been implemented, but there is a need for improvement in directing policies toward poverty alleviation, economic empowerment, and sustainable natural resource management.

Environmental problems, especially rivers, have become a global issue that must receive more attention because of their extraordinary impact on society. Some residents of Bedewang village still use the river for bathing, defecating and washing. However, ironically, most people are apathetic and care less about preserving the river, where residential waste is the biggest contributor to river pollution because they throw away kitchen waste, leftover food and diapers around the watershed. This Community Service activity aimed to increase public awareness of the environment through the SEKARDADU program in the Bedewang Watershed, Songgon - Banyuwangi. The methods used include socialization, providing education, and direct assistance. The activity results showed that residents can directly implement the socialization/education activities provided, the understanding of using clean water for daily needs and forming a community commitment to preserving the river so that disasters do not occur due to environmental damage.
