Abstract

Seagrass ecosystems play a crucial role as feeding grounds, spawning sites, and refugia for various marine organisms, including macrozoobenthic communities. Macrozoobenthos are ecologically significant in energy cycling, organic matter decomposition, and serve as bioindicators for assessing environmental quality. This study aimed to analyze the composition, dominance, and diversity of macrozoobenthos in the seagrass beds of Pari Island and to evaluate their implications for coastal ecosystem management. Samples were collected from 27 research plots in the seagrass meadows of Pari Island between September and November 2021 using a hand corer to a depth of 10–15 cm. Sediment samples were sieved, the macrozoobenthic organisms were sorted, identified, and grouped into five major taxa: Polychaeta, Crustacea, Mollusca, Echinodermata, and other minor phyla. Community structure was assessed by calculating absolute abundance, relative abundance, as well as ecological indices including the Shannon–Wiener diversity index, Pielou’s evenness, and Simpson’s dominance index. A total of 2,386 individuals were recorded, consisting of Polychaeta (73.7%), Crustacea (13.7%), minor phyla (11.8%), Echinodermata (0.5%), and Mollusca (0.3%). The diversity index ranged from 0.92 to 1.49, evenness from 0.48 to 0.80, and Simpson’s dominance index (C) from 0.44 to 0.69. These results indicate that Polychaeta dominated nearly all sampling stations, whereas other taxa were only sporadically present. The macrozoobenthic community structure in Pari Island reflects low to moderate diversity, with uneven distribution among taxa. The findings highlight the ecological importance of seagrass beds as primary habitats for benthic infauna, while also demonstrating their vulnerability to anthropogenic pressures. Consequently, this study provides a scientific basis to support seagrass conservation, benthic bioindicator-based monitoring, and sustainable coastal management in the Kepulauan Seribu region.

Abstract

The rapid growth of seafood consumption has raised concerns about food safety due to microplastic contamination in marine organisms. This study investigated the occurrence and characteristics of microplastics in commercially important marine fish marketed in Jakarta Bay, one of Indonesia’s most densely populated and industrialized coastal regions. A total of 160 specimens representing eight species were collected from five major fish markets between December 2023 and January 2024. Microplastics were extracted from gills and gastrointestinal tracts using enzymatic digestion, density separation, and confirmed by ATR-FTIR spectroscopy. Results revealed that 93.8% of the samples contained microplastics, with an average of 3.65 ± 2.34 particles per individual (0.12 ± 0.21 particles/g). Carnivorous and benthopelagic species exhibited significantly higher contamination levels compared to omnivorous and planktivorous species. Most particles were fragments and fibers (~70%), predominantly within the 2000-5000 µm size range. Seven polymer types were identified, with polyethylene, polypropylene, and polystyrene as the most frequent. These findings indicate that Jakarta Bay is a hotspot of plastic pollution, posing potential risks to food security and public health. Continuous monitoring, standardized risk assessments, and improved waste management strategies are urgently needed to mitigate the impacts of microplastic contamination on fisheries and human consumers.

Abstract

Microgreens are young vegetable plants harvested 7–14 days after planting. They boast high nutritional content and have growing market potential in line with public awareness of a healthy lifestyle. This study aims to assess the application of microgreen cultivation in the Hasanah Farmers Group as an effort to diversify their farming business and increase farmer income. The research was conducted using a participatory Rural Appraisal (PRA) approach, involving farmer group members at every stage, from media preparation, planting, maintenance, harvesting, and marketing. The results indicate that microgreen cultivation can be carried out using simple technology, at low cost, while generating significant added value. Tray microgreen harvests yield an average of 250–300 grams per cycle with a selling price of IDR 20,000–25,000 per 100 grams. The profit margin for microgreen farming in the Hasanah Farmers Group reaches 45–55% compared to production costs. In conclusion, microgreens have the potential to become a promising alternative commodity to improve farmer welfare through a modern, sustainable agricultural system

Abstract

Learning will be more meaningful if there is encouragement or a desire to learn. This encouragement is what is called learning motivation. To build learning motivation, efforts were made, including the implementation of the Problem-Based Learning (PBL) model and the Culture-Based Approach (CRT). The purpose of this study was to improve the learning motivation of tenth-grade Anggrek students at SMAN 6 Palu, Central Sulawesi, through the implementation of the PBL model and the CRT approach. This study used classroom action research (CAR). The research design adopted the Kemmis & MC Taggart design. The study was conducted in two cycles, each consisting of planning, implementation, observation, and reflection. Data were obtained through questionnaires administered to students in cycles 1 and 2. Data analysis was conducted descriptively. Based on the data analysis, the results showed an average increase in student learning motivation of 74 in cycle 1, which is considered quite good, and 80 in cycle 2, which is considered good. This proves that there is an increase in student learning of the Problem Based Learning (PBL) on cultural approach (CRT).

Abstract

This study aims to explore the potential of halophilic actinobacteria from Talise salt ponds, Central Sulawesi, as candidates for producing antibacterial compounds. The study was conducted through isolation, macroscopic and microscopic characterization, biochemical tests, and testing of antibacterial activity against S. aureus and E. coli using the disc diffusion method. Data were analyzed descriptively based on observations and inhibition zone measurements. The results showed the acquisition of five halophilic actinobacteria isolates, namely TL1, TL2, TL3, TL4, and TL5, which have characteristics similar to the genus Streptomyces. Biochemical tests indicated unique metabolic capabilities, including the production of the catalase enzyme and sugar utilization in the TSIA test. All isolates showed antibacterial activity, with isolate TL5 providing the largest inhibition zone, namely 16.5 mm against E. coli and 6.5 mm against S. aureus. These findings indicate that halophilic actinobacteria from Talise salt ponds have the potential to be a source of new antibiotics relevant for drug development in addressing antibiotic resistance

Abstract

The consumption of chicken continues to rise each year. However, the complete nutritional content in chicken meat makes it highly favored by bacteria. The allicin content in garlic can prevent the growth of various microorganisms that can cause meat spoilage. This study aims to determine the effect of varying concentrations of garlic solution (Allium sativum) on bacterial growth in chicken meat. The method used is an experiment employing a Completely Randomized Design (CRD) with three treatments: marinating chicken meat in garlic solution at concentrations of 0% (Control), 10%, and 20%, each with three replications. The research was conducted in November 2024 at the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, State University of Padang. The results obtained indicate that the optimum concentration of garlic solution as an antibacterial compound is 10%, with an average total microbial count of 2,3 x 104 cfu/g

Abstract

During practical work, students tend to have difficulty describing the objects they are observing. This research aims to analyze the relationship between visual representation and students' factual knowledge on plant anatomy material. This type of research is descriptive correlational. The sample in this study included 33 students from a biology education study program at one of the universities in Bandung. The instruments used in this research include image analysis rubrics and tests. The image analysis rubric instrument is used to obtain data related to image representation abilities, while the test instrument is used to obtain data on students' factual knowledge. Before the correlation test is carried out, a prerequisite test is carried out first to obtain normal distribution results and linear regression. Based on the results of the correlation test, results were obtained with a significance of 0.031 < 0.05. Based on these results it can be concluded that there is a relationship between the two variables, namely between visual representation and factual knowledge. Furthermore, an r value of 0.377 was obtained, indicating that the relationship between visual representation and students' factual knowledge was categorized as low
