The method of catching fish carried out by traditional fishermen in "fisherman-cage" still uses petromax lamps with kerosene or lamps from generators that run on diesel fuel. These situations could cause oil spills that pollute the environment and are prone to fires. This community service program introduces a new energy source, by designing a solar-based lighting system (PLTS), where sunlight is converted into electric current and stored in batteries as a backup current at night. In this design, fishermen can optimize lighting by adjusting the position of the lamp according to the sea level at high and low tide to attract plankton and fish to enter the cage net. The design of the prototype has been tested in the TI-MR ITEBA laboratory with very satisfactory results, and then it was continued with serial production of 10 sets to be handed over to the fishing community. The fisherman directly recognized the success of the 10 sets of PLTS in increasing fish catches and getting environmentally friendly when the team visited the cage location

The low resistance of wood as a frame material for traditional fishing boats against splashing sea water, humidity, and high-temperature fluctuations was studied in this study by adding coconut coir fiber to wood paint, where this mixture will become an anti-weathering composite material. To make compatibility between the fibers from coir which are water-absorbing (hydrophilic) and alkyd paints which are water-repellent (hydrophobic), the author gives special treatment to the coco fibers through an acetone pre-treatment process and hot alkali (hot alkali treatment) by soaking fiber in 10% high-temperature sodium hydroxide NaOH solution. Soaking in this solution is able to modify fibers that have a rough surface and reduce hydrogen bonding thereby improving the interfacial bond between the fiber and the filler in the composite. The results obtained were that the addition of fiber with a weight fraction of 3.40% to the alkyd paint matrix made the composite the most optimal anti-weathering coating.

Pengabdian kepada Masyarakat (PkM) yang dilaksanakan bertujuan untuk pemahaman dan kesadaran masyarakat tentang masalah erosi pantai dan solusinya.Penahan erosi pantai dari tempurung kelapa adalah solusi ramah lingkungan yang memanfaat-kan limbah tempurung kelapa sebagai bahan utama yang jumlahnya melimpah dan hampir tidak memiliki nilai jual yang hanya dianggap sebagai sampah. Tempurung kelapa yang memiliki kekuatan dan ketahanan alami digunakan untuk mengurangi laju erosi akibat abrasi air laut. Teknik ini melibatkan penempatan tempurung kelapa yang disusun membentuk formasi kura-kura di sepanjang garis pantai yang rentan terhadap erosi. Selain itu, tempurung kelapa dapat digunakan bersama dengan vegetasi pantai untuk menambah stabilitas tanah. Tempurung kelapa dapat dijadikan pelindung serta media tanam pohon bakau, sebelum akhirnya pohon bakau akan tumbuh besar dengan akar yang menjulur dengan kuat. Akar tanaman pantai ini akan tumbuh di antara tempurung kelapa dan semakin memperkuat perlindungan terhadap erosi. Metode ini tidak hanya efektif secara ekologis, tetapi juga ekonomis karena menggunakan bahan yang mudah didapatkan dan murah, terutama di daerah tropis yang memiliki banyak kelapa. Selain itu, dengan sifat biodegradabilitas tempurung kelapa yang memungkinkan integrasi ke dalam lingkungan alam secara alami tanpa mencemari atau merusak ekosistem pantai. Keuntungan lain adalah mensukseskan program “carbon neutrality” dengan berkembangnya hutan bakau yang menjadi ekosisistem pesisir yang akan membantu dalam penyerapan karbon. Berdasarkan hasil evaluasi kegiatan dan pengamatan tim pengabdian, program pelatihan pembuatan formasi kura-kura dari tempurung kelapa telah memberikan manfaat nyata bagi masyarakat sasaran

Background: Brackish water is a unique ecosystem formed from the mixing of seawater and freshwater, commonly found in coastal areas and swamps. However, its existence is now threatened by heavy metal pollution from industrial activities. Unprocessed heavy metals are discharged into brackish water, contaminating the ecosystem and endangering human health, especially coastal communities that rely heavily on this water resource. Methods: To address this problem, the Community Service Program (PkM) proposes the application of a water treatment installation technology based on blood cockle shell powder filtration in the area of the Indonesian Traditional Fishermen’s Union (KNTI), specifically in Dangas Village, Batam. Blood cockle shells (Anadara granosa) were chosen because of their high calcium carbonate (CaCO₃) content and their effectiveness in absorbing heavy metals. Results: Based on p-value analysis, there was a significant difference in partner satisfaction before and after the PkM activity. Conclusion: This approach is expected to provide an environmentally friendly and sustainable solution to combat brackish water pollution, improve the quality of life of coastal communities, and prevent long-term health impacts caused by heavy metal exposure.
