Abstract

Seed quality is a key factor in determining the success of germination and productivity of rice plants. This study aims to evaluate the seed growth potential of 21 rice varieties (Oryza sativa L.) consisting of local, national, and introduced varieties through correlation analysis and Principal Component Analysis (PCA). Four parameters observed include Maximum Growth Potential (PMP), Germination Power (DB), Plumule Length (PP), and Radicle Length (PR). The study was conducted at the Biology Laboratory, Satya Terra Bhinneka University, using a completely randomized design with three replications. The analysis results showed significant variations among varieties for all observed parameters. The PCA value showed that two principal components (PC1 and PC2) explained 78.1% of the total variability. The PTM and DB parameters had high negative loadings on PC1, indicating that this component represents seed viability, while PP and PR had positive loadings on PC2, which described the morphological vigor of the seedlings. The Sigupai, Tinggong, and Inpago 12 varieties were in the quadrant with negative PC1 and positive PC2 values, indicating a combination of high viability and strong seedling growth. Correlation analysis showed a very strong positive relationship between PTM and DB (r = 0.98; p < 0.001), while the correlation between physiological and morphological parameters was weak. Thus, PCA and correlation analysis proved effective in identifying superior rice varieties based on seed viability and vigor traits, potentially supporting variety selection in rice seed management and development.

Abstract

Microbiological pollution of river water is one of the major risks to public health. Escherichia coli is used as an indicator of fecal contamination in waters. The Aur River is a tidal river in Palembang City that receives domestic waste runoff from the activities of the surrounding community. This study aims to analyze the total concentration of coliform and identify the dominant coliform type in the Aur River. The research was carried out along 2.5 km with three observation stations (upstream, middle, and downstream). Water sampling was carried out at five points at each station, and coliform analysis referred to SNI 3554. The results showed that the total coliform concentration at the upstream station was 5.24 × 10⁶ ± 1.1 × 10⁵ CFU/100 mL, the middle station was 1.1 × 10⁴ ± 5.5 × 10² CFU/100 mL, and the downstream station was 9.2 × 10⁶ ± 1.1 × 10⁵ CFU/100 mL, all of which exceeded the quality standard of 5 × 10³ CFU/100 mL. The dominant coliform types identified include Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli, and Enterobacter sp. These results show that the Aur River has experienced significant microbiological pollution, so efforts to control and manage water quality in a sustainable manner are needed.

Abstract

This study aims to determine the effect of the application of fermented walking mill rice bran using Effective Microorganisms (EM4). The observed parameter is the quality of purebred chicken yolks. The research was carried out through three stages, namely the comparison of the nutritional quality of DPPB with factory bran, DPPB fermentation with three EM4 formulations, and the application of fermented DPPB in purebred chickens. The results showed that the nutritional content of DPPB was lower than the quality standards of factory bran, especially in the protein content. The fermentation process increased the protein content of DPPB by 1.2%. The application of fermented DPPB resulted in the highest protein content in the P4 treatment (13.2%), the highest fat content in the P3 treatment (5.6%), and the highest cholesterol content in the control treatment (56.2%). Thus, DPPB fermentation using EM4 has the potential to increase the nutritional value of bran as an alternative feed ingredient for purebred chickens.

Abstract

Coffee Liberica (Coffea liberica) is one of the coffee varieties that has the potential to be developed, but information on the effect of roasting levels on caffeine content is limited. Meanwhile, caffeine levels are an important parameter that affects quality and sensory characteristics. This study aims to qualitatively identify the presence of caffeine and quantitatively determine caffeine levels in liberica coffee with different roast levels, namely light, medium, and dark roast. The research was conducted experimentally in the laboratory using the Qualitative Test of the Parry method and the quantitative test of the UV-Vis Spectrophotometry method. The sample was in the form of liberica coffee beans at three roasting levels and was repeated three times. The results of the qualitative test showed that all samples of liberica coffee at the three levels of positive roasting contained caffeine which was characterized by the formation of a green color in the Parry test. The results of the quantitative analysis showed that the highest caffeine level was found at the light roast level of 116.412 mg/g, followed by medium at 102.381 mg/g, and the lowest at dark roast at 91.036 mg/g. The decrease in caffeine content as the temperature increases and the length of the roasting time shows that the roasting process has a significant effect on the stability of caffeine. The results of this study are expected to make a scientific contribution to the development of the chemical study of Liberica coffee, as well as become a practical reference for coffee industry players in determining the roasting level according to the characteristics of caffeine.

Abstract

This research aims to develop a biodiversity Practicum Worksheet (LKP) that is oriented towards improving students' understanding of environmental concepts and attitudes. The research uses the Research and Development (R&D) method with a 4D model that is limited to the development stage. The development stages include analysis of learning needs, design of LKP structures, and product validation by experts. Data was obtained from the validation results and analyzed descriptively to determine the feasibility level of the product. The validation results showed that the LKP developed was in the category of feasible use with a feasibility percentage of 77%. However, there are several aspects that still need improvement, especially in the deepening of the material, linguistic clarity, as well as the completeness and clarity of practicum tools and materials. The LKP developed integrates contextual practicum activities, data analysis, and reflection on environmental care attitudes, so that it has a practical contribution as a biology learning tool that is not only procedural, but also encourages the linkage between observation results and the concept of biodiversity. Thus, this LKP has the potential to support more meaningful learning after improvements are made according to the validator's recommendations.

Abstract

Pandanus tectorius is a non-timber forest product that has important ecological, cultural, and economic value for coastal communities. This study aims to analyze the utilization of Pandanus tectorius in MSME-based creative industries through an ethnobotanical approach in Banjar District, Pandeglang Regency, Banten. This approach is used to examine local knowledge, processing techniques, and pandan cultural values in the community's economic system. Data was collected through in-depth interviews, observation of the production process, and descriptive analysis. The results show that pandans have been used for generations as the main raw material for various woven products, such as mats, hats, and bags. Based on field findings, pandan handicraft activities involve more than 100 active and growing weavers in the last five years, with a marketing reach to the national level as well as limited-scale exports. However, the development of pandan crafts still faces obstacles in the form of limited raw materials due to land conversion, the lack of regeneration of young artisans, and limited production technology. These findings affirm the importance of integrating ethnobotanical knowledge in strengthening MSMEs and developing a sustainable pandan creative industry.

Abstract

Indonesia is one of the countries with the highest level of biodiversity in the world, including plant diversity from the Fabaceae family which has an important role ecologically and economically. The Fabaceae family contributes to maintaining soil fertility through nitrogen fixation capabilities, and is widely used as a source of food, medicine, animal feed, and shade plants. The existence of Fabaceae plants can be found in various types of ecosystems, such as swamps, forests, and agricultural land. This study aims to inventory the diversity of plant species of the Fabaceae family found in Tabing Rimbah Village, Mandastana District, Barito Kuala Regency, South Kalimantan. The research method used is an exploratory approach through direct observation in the field, recording morphological characters, photo documentation, and species identification using taxonomic literature and PlantNet applications. The results of the study showed that as many as 16 species of plants from the Fabaceae family were found with variations in habitus in the form of herbs, shrubs, and trees. The diversity of these species shows that the environmental conditions in Tabing Rimbah Village are quite supportive of the growth and development of Fabaceae plants. These findings affirm the importance of biodiversity inventory as a basis for sustainable conservation and management of local biological resources.

Abstract

This study aims to identify shrub insect species around the Bodogol Nature Conservation Education Center (PPKA Bodogol), Bogor, West Java. The research uses an exploratory descriptive approach by sampling through the free roaming method on shrub vegetation. Specimens were collected using sweeping net and hand collecting techniques from morning to noon, then analyzed descriptively based on the number of individuals, the number of species, and the composition of the order and family. The results of the study recorded 20 species from 8 orders, with the dominance of Orthoptera (7 species) and Lepidoptera (4 species). The families Acrididae and Scarabaeidae are the most abundant taxons, while Xylotrupes gideon is the species with the highest number of individuals. The dominance of these families and species indicates that the vegetation of the PPKA Bodogol bush provides habitat conditions that support herbivorous and detritivore insects that play an important role in energy flow and ecosystem stability. These findings show that shrub vegetation has a strategic role as a functional habitat for insects and can be used as basic data in planning, management, and conservation of insect biodiversity in conservation areas.

Abstract

Microplastic pollution in the waters of Lake Toba has the potential to accumulate in aquatic biota, including tilapia (Oreochromis niloticus) cultivated in floating net cages. The presence of microplastics in aquatic organisms is an important concern, because it has the potential to disrupt the balance of aquatic ecosystems and pose a risk to food security for humans. This study aims to identify the shape and color of microplastics in the gills and digestive tract of tilapia, as well as analyze the differences in abundance between the two organs. The research was carried out in June-August 2025 using a quantitative descriptive method. Fish samples were taken from three stations in the waters of Lake Toba, Simalungun Regency, namely tourist areas, boat transportation activities, and residential areas. Microplastic identification was performed visually using a microscope after the degradation of organic matter by the Fenton method. The results showed that the abundance of microplastics in the gill organs was 32 particles/individual, while in the digestive tract as many as 31 particles/individual. The microplastics found are dominated by fibers, fragments, and films with the main colors being green, black, red, brown, and transparent. The results of the independent sample t-test showed a value of p = 0.787 (p > 0.05) which indicated that there was no significant difference in microplastic abundance between the gills and the gastrointestinal tract. These findings confirm that microplastics have been distributed relatively evenly in tilapia organs, so that they have the potential to have an impact on the health of Lake Toba's aquatic ecosystem and food safety from aquaculture fisheries.

Abstract

Microplastic pollution in the marine environment is a global issue that has the potential to threaten aquatic organisms, including marine fish consumed by humans. The presence of microplastics in fish can impact the health of marine ecosystems and risk entering the human food chain. This study aims to analyze the shape, color, abundance, and differences in the abundance of microplastics in the gills and digestive tract of marine fish for consumption. The study was conducted in June-August 2025 at the Tanjung Beringin Fish Farming Site (TPI) in Serdang Bedagai Regency. The sample consisted of five fish species, namely Sardina pilchardus, Selaroides leptolepis, Rastrelliger brachysoma, Parastromateus niger, and Euthynnus affinis, each with 10 individuals/fish species. Microplastics were isolated from the gills and digestive tract, then identified based on the shape and color of the microplastics using a stereo microscope. Microplastic abundance data were analyzed using a one-way ANOVA test. The results showed that the microplastics found were dominated by fibers (56%), fragments (42%), and films (2%). The colors of the identified microplastics included red (81%), black (73%), green (37%), blue (6%), and transparent (3%). The highest microplastic abundance was found in the digestive tract of Euthynnus affinis (41.9 particles/individual), while the lowest was found in the gills of Rastrelliger brachysoma (26.5 particles/individual). The ANOVA test showed significant differences in microplastic abundance (p < 0.05), especially between Sardina pilchardus and Parastromateus niger, and between Selaroides leptolepis and Euthynnus affinis.
