Abstract

Carbon tetrachloride is well known as hepatotoxic, including toxic substances commonly used to induce liver damage. Sugar palm (Arenga Pinnata Merr.) is a type of palm plant that is used as a source of antioxidants, one of which is part of the fruit. The aim of this research is to determine the effect of administering ethanol extract of palm fruit (Arenga pinnata Merr.) on the morphology and liver function of rats (Rattus norvegicus L.) which is induced by carbon tetrachloride. This research method used a completely randomized design consisting of 20 mice grouped into 5 groups, namely negative control, positive control, P1 (ethanol extract of palm fruit 90 mg/kg BW), P2 (180 mg/kg BW), P3 (360 mg /kg BW) with each group having four repetitions. Data analysis was carried out using the One Way ANOVA test and continued with the Duncan test. The results of this study show that carbon tetrachloride at a dose of 1 mL/kg BW can damage the morphological appearance of rat liver and increase SGOT and SGPT levels. Giving ethanol extract of palm fruit to the P3 group at a dose of 360 mg/kg BW was the most effective dose to improve liver morphology and reduce SGOT and SGPT levels in white rats induced by carbon tetrachloride.

Abstract

Staphylococcus aureus is a Gram-positive bacteria that is widespread on human skin and mucosa and can cause a range of ailments, from food poisoning to serious and life-threatening infections. Food handlers are directly linked to food hygiene since they can be a source of infection. The purpose of this study was to detect the presence of S. aureus bacteria in the nasal cavity of canteen handlers in the University of Mataram. This study used a cross-sectional descriptive research design with a population of all food handlers at the University of Mataram canteen. This study was conducted through the stages of isolation, culture, Gram staining, and biochemical detection. The sampling technique used in this study was purposive sampling. This study was conducted on 10 samples of nasal cavity swabs of food handlers in the canteen of the University of Mataram with 5 (50%) positive samples of S. aureus. Meanwhile, the other 5 (50%) samples were indicated to be types of Staphylococcus sp. other species. It can be concluded that the presence of S. aureus was found in food handlers at the University of Mataram Canteen and food handlers are also expected to improve the application of hygiene and sanitation to themselves.

Abstract

Bamboo in Indonesia grows in clumps that create habitats that support biodiversity that can be studied through bioindicators, such as spiders that act as biological control agents as well as indicators of ecosystem diversity. This research was carried out with the aim of determining the diversity of spiders in bamboo clumps. The spider collection method is Hand Collecting and Beating. The results of the study found 14 species from 14 genera, 10 spider families consisting of 38 individuals. The species with the highest number of individuals is Ctenus hibernalis which reaches 14 individuals, while most other species only have a number of individuals between 1 to 3. This variation in the number of individuals per species is likely due to factors such as habitat differences, spider behavior, and the effectiveness of each collection method.

Abstract

Neem, a member of the Meliaceae family, is recognized to have the ability to decrease blood glucose levels. The study’s goal is to determine the neem gum (NG) impact in overcoming hyperglycemia in Wistar rats. There were three groups of rats in this study: (1) control, (2) hyperglycemic group (which got Streptozotocin (STZ) treatment but not NG treatment), and (3) hyperglycemic group (which got STZ treatment and 15% NG treatment) for three weeks. The T test results revealed notable variations before and after giving STZ. The finding indicated the blood glucose level before STZ induction in control was 86.50 ± 3.15 mg/dL, and the diabetic rat group (treated with STZ) was 87.60 ± 4.56 mg/dL. After STZ induction (7th day), there was a noteworthy rise in amount of glucose, namely 435.34 ± 120.33 mg/dL compare to the STZ treatment. The Duncan Multiple Range (DMRT) test showed there is no discernible difference between the STZ and NG treatments; however, there was a downward trend on days 14, 21, and 28. The conclusion of this study is that 15% NG has failed to decreas ehyperglycemia to normal blood glucose levels.

Abstract

Tangkas Lake, a freshwater swamp in Muaro Jambi and Batanghari, is dominated by Homalium sp., but its overall plant diversity remains undocumented. This study inventories plant species as a baseline for conservation. Plant sampling was conducted using transect and plot methods in two locations, Pulau Tepus and Rawa Liontin, over two months. A total of 37 species from 21 families were recorded, with higher diversity in Pulau Tepus (31 species, dominated by Myrtaceae, Elaeocarpaceae, and Euphorbiaceae) compared to Rawa Liontin (6 species, dominated by Homalium sp.). Species diversity indices were moderate in Pulau Tepus but lower in Rawa Liontin. Species richness was highest in Pulau Tepus for tree (4.6) and seedling (4.5) stages, while pole-stage richness was 3.7. Rawa Liontin had low species richness across all stages, with low evenness in both sites. Environmental factors varied, with Pulau Tepus experiencing wider temperature fluctuations (23–30°C), lower light intensity, and sandy loam soils, while Rawa Liontin had a narrower temperature range (25.5–27.3°C), higher light intensity, and similar soil texture. Soil pH ranged from 4.29 to 6.21. These findings highlight the need for conservation, particularly in Rawa Liontin. Further research is needed to support habitat restoration and long-term monitoring.

Abstract

The Sumatran striped rabbit (Nesolagus netscheri) is endemic to the highland forests of Sumatra. This study aims to analyze the level of awareness and knowledge of universamong students about the endangered species Nesolagus netscheri, whose population is easingly threatened. This species has high ecological value, but the lack of information and knowledge about this species can worsen its condition in nature. This study used a survey approach by distributing questionna to junior and senior high school students in West Sumatra to measure their understanding of this species. The results showed that students' knowledge of the Sumatran Striped Rabbit is relatively low, although they have an awareness of the importance of conservation of endangered species. In conclusion, there is a need to improve specific environmental education programs to introduce local biodiversity to the younger generation. We suggest that by increasing student awareness and knowledge will encourage active participation in the conservation of this species and their environment in the future.

Abstract

Cemara Beach in Banyuwangi Regency has a unique mangrove ecosystem with a river flow that limits the tidal area with the land behind it. This study aims to determine the structure and composition of mangroves in Cemara Beach and its zoning. The method used is a vegetation survey with a transect plot. Data were analyzed using ecological indices and zoning illustrated from the results of vegetation surveys and observations. The results show that the Casuarina equisetifolia species has the highest important value index (IVI) in tree-level vegetation with an IVI value of 128.29%, while the highest IVI at the sapling level is owned by the Rhizophora mucronata species of 86.72% and the Acanthus ilicifolius species of 64.41% at the seedling level. The species diversity index (H') and dominance index (D) of mangroves in Cemara Beach are classified as moderate with average values ​​of 1.21 and 0.35. Then the species evenness index (E) of mangroves in Cemara Beach is included in the high category with an average E value approaching one at 0.78, while the species richness index (R) is classified as very low with an average value of 0.93. The zoning formed in mangrove vegetation in Cemara Beach is in sequence from sea to land, namely Casuarina equisetifolia, Rhizophora mucronata, Acanthus ilicifolius, Avicennia alba, Sonneratia alba, and Excoecaria agallocha. These findings suggest the need for targeted conservation and rehabilitation strategies that consider the natural zonation and dominance patterns of mangrove species to maintain the ecological balance of Cemara Beach.
