Abstract

Microplastic pollution is a significant threat to aquatic ecosystems and human health, particularly in Indonesia, a major contributor to plastic waste. This study investigated the presence and characteristics of microplastics in three commonly consumed fish species from Tondano Lake, North Sulawesi: mujair (Oreochromis mossambicus), payangka baru (Oxyeleotris marmorata), and payangka lama (Ophiocara poropechala). Analysis of gills and gastrointestinal tracts (GIT) from 11 fish samples revealed microplastic contamination in all species. Mujair exhibited the highest microplastic abundance, predominantly fragments in both gills and GIT. Payangka baru showed more fibers in the GIT and fragments in the gills, while payangka lama had more fibers in the GIT and fragments in the gills. A positive correlation was observed between fish body weight and microplastic accumulation in the GIT, but not the gills. The findings confirm microplastic contamination in Tondano Lake fish, highlighting the need for stricter waste management and further research on human health implications.

Abstract

Pakoba fruit is one of the endemic flora of North Sulawesi which is rich in nutrients and has the potential to be fermented. The fermentation process occurs due to the bacteria in the fruit, including lactic acid bacteria (LAB). One of the interesting products from LAB fermentation is that it can produce secondary metabolites which have the potential to produce exopolysaccharides, namely high molecular weight and biodegradable polymers. This research aims to determine whether LAB can be obtained from fermentation of Pakoba marination and what types of LAB produce exopolysaccharides based on their phenotypic characteristics. This research uses a qualitative descriptive method to characterize the type of LAB and observe the exopolysaccharides produced by the bacteria. This research succeeded in isolating and identifying 10 LAB isolates based on their morphological and biochemical characters. Four isolates named MP(1)5.2, MP(1)7.1, MP(3)6.3, MP(3)7.2 can produce exopolysaccharides with a soft character but not mucus, where bacterial exopolysaccharides are believed to increase probiotics in the digestive tract. Genus level recognition (generic assignment) based on profile matching revealed that these four bacteria were from the genus Lactobacillus.

Abstract

Abstrak Mangrove adalah tanaman khas daerah tropis yang dapat ditemukan baik di darat maupun di lautan. Mangrove berperan besar dalam menjaga keseimbangan ekosistem pantai dan pesisir. Upaya konservasi diperlukan karena ekosistem mangrove di berbagai tempat yang terdapat di Pantai Pangalisang Pulau Bunaken akhir-akhir ini mengalami kerusakan dan pertumbuhan yang tidak baik. Tujuan dari proyek pengabdian ini adalah untuk meningkatkan pengetahuan, pemahaman, dan kesadaran mahasiswa akan nilai pengembangan dan pengelolaan kawasan mangrove secara berkelanjutan. Metode yang digunakan dalam kegiatan ini adalah persiapan, sosialisasi, dan penanaman mangrove. Pelaksanaan pengabdian ini melibatkan 6 dosen Unima beserta 65 mahasiswa yang tergabung dalam organisasi HMJ Biologi FMIPAK Unima dan IKAHIMBI Wilayah Kerja VIII. Hasil dari kegiatan pengabdian ini menunjukkan bahwa mahasiswa merasakan manfaat dari pengembangan pola pikir peduli lingkungan pantai dan pesisir melalui penanaman mangrove secara langsung. Di samping itu,mereka menjadi sadar akan pentingnya lingkungan mangrove bagi kelangsungan hidup manusia serta berbagai jenis tumbuhan dan satwa. Kata kunci: konservasi; penanaman mangrove; peduli lingkungan Abstract Mangroves are plants typical of tropical regions that can be found both on land and in the ocean. Mangroves play a big role in maintaining the balance of coastal ecosystems. Conservation efforts are needed because the mangrove ecosystem in various places on Pangalisang Beach on Bunaken Island has recently experienced damage and poor growth. The aim of this service project is to increase students' knowledge, understanding, and awareness of the value of sustainable development and management of mangrove areas. The methods used in this activity are preparation, outreach, and planting mangroves. The implementation of this service involved six Unima lecturers and 65 students who were members of the HMJ Biology FMIPAK Unima organization and IKAHIMBI Work Area VIII. The results of this service activity show that students feel the benefits of developing a mindset of caring for the coastal and coastal environment through direct mangrove planting. In addition, they become aware of the importance of the mangrove environment for human survival as well as various types of plants and animals. Keywords: conservation; planting mangroves; caring for the environment
