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

Homegardens have long been a vital traditional agroforestry system supporting the livelihoods of Indonesian communities, particularly in terms of food security. This study aims to deepen the understanding of the role of homegardens in national food security by focusing on a case study of the Local User Value Index (LUVI) for food crops in homegardens in Pujon, Malang Regency, East Java. The research methodology involved collecting local knowledge from the community and applying the Pebble Distribution Method (PDM) to calculate the significance value of plants across various utility categories (LUVI). The findings indicate that homegardens play a significant role in meeting local food needs, particularly through the production of food crops, vegetables, fruits, herbs, and natural dyes. Crops such as maize and cassava serve as important staple food alternatives in areas with limited agricultural land. The preference for plant usage is influenced by geographical factors, community preferences, and the utility of the plants. This study provides deeper insights into the potential of homegardens and their role in supporting food security, with the aim of contributing to the advancement of knowledge and agricultural policy development in the future.

Abstract

ARTICLE HIGLIGHTSMangrove species like Acanthus ilicifolius and Avicennia marina aid food and health.Correlation and PCA reveal food, medicine, and firewood as key use dimensions.Location trends: Sondaken for firewood, Baboi for medicine, Mantehage for knowledge.This study supports mangrove ethnobotany and promotes community bioconservation.ABSTRACTMangrove ecosystems play a vital ecological and socio-economic role along coastal regions. However, their sustainable utilization faces significant challenges due to habitat degradation and modernization. This study aimed to characterize the ethnobotanical utilization of mangroves by coastal communities within Bunaken National Marine Park (BNMP) and its surrounding small islands, while exploring their potential for food and medicinal bioprospecting. Data were collected through questionnaire surveys, in-depth interviews with informants, and field observations within coastal communities in four locations such as Bahoi, Likupang Barat District, North Minahasa, Sondaken, Tatapaan District, South, Alung Banua, Bunaken Archipelago District, Manado, and Mantehage, Wori District, North Minahasa Regency. The data were subsequently analyzed descriptively, followed by Principal Component Analysis (PCA) and heatmap visualization. The findings revealed that specific species such as Acanthus ilicifolius and Avicennia marina occupy central roles as sources of food and traditional medicine, emphasizing the close integration between subsistence needs and community health. Correlation analysis and PCA indicated that the categories of food, medicine, and firewood represent the dominant dimensions of utilization, while cultural functions and species knowledge serve as secondary differentiators. Location-based variations underscored the heterogeneity of utilization practices, with Sondaken being more prominent in firewood use, Bahoi in ethnomedicine, and Mantehage in biodiversity knowledge. These findings highlight the necessity of mangrove management that extends beyond ecological conservation to include local wisdom as a foundation for bioprospecting, thereby supporting food security, health, and the well-being of coastal communities. Thus, this research significantly contributed to the literature on mangrove ethnobotany and provided a scientific framework for community-based bioconservation strategies in Indonesia.

Abstract

Antimicrobial resistance has accelerated the search for alternative antibacterial agents derived from natural products. Water hyacinth (Eichhornia crassipes) is an invasive aquatic weed that is abundant in Indonesian waters, yet rich in secondary metabolites such as flavonoids, tannins, alkaloids, and saponins with antibacterial potential. This study aimed to evaluate the inhibitory activity of the ethanol extract of water hyacinth leaves against Escherichia coli (Gram-negative) and Propionibacterium acnes (Gram-positive). A descriptive-exploratory laboratory design was used. Leaf samples collected from Lake Tondano were extracted by maceration in 96% ethanol and concentrated using a rotary evaporator. Antibacterial activity was assessed by the well-diffusion method at 100% extract concentration, with 30% amoxicillin as the comparator, incubated at 37°C for 24 hours. The extract produced mean inhibition zones of 7.0 mm against E. coli and 5.7 mm against P. acnes, both classified as moderate according to the Davis & Stout scheme, whereas amoxicillin produced zones of 8 mm and 7 mm. The ability of the extract to inhibit both Gram-positive and Gram-negative bacteria indicates a broad spectrum of activity. These findings confirm that water hyacinth leaves are a promising source of natural antibacterials while adding value to aquatic weed management.
