Abstract

Bioethanol is an energy source obtained through fermentation. In bioethanol production, Persea americana seeds are used as a fermentation medium because they contain lots of carbohydrates. This research aims to determine the effect of additional nutrients (NPK and urea fertilizer) required by Saccharomyces cerevisiae by varying the nutritional variables in the form of NPK and urea fertilizer. The process of making bioethanol goes through stages: making Persea americana seed flour, hydrolysis process using 6% HCl, then fermentation process, and distillation process. This research was carried out with the addition of Nutrients in the form of NPK and Urea Fertilizer with 5 treatments, namely: A) 100% yeast (no addition of Nutrients); B) 100% NPK (4 g); C) 100% Urea Fertilizer (4 g); D) 50% NPK and 50% Urea Fertilizer (4 g NPK and 4 g Urea Fertilizer); and E) 75% NPK and 25% Urea Fertilizer (3 g NPK and 1 g Urea Fertilizer), and varying the length of fermentation time to 13, 19, and 25 days. Success parameters are assessed through the bioethanol yield produced by each treatment. The research results showed that the highest bioethanol (29.7 ± 0.47%) was composition E (NPK 75% and Urea Fertilizer 25%) with a fermentation time of 25 days.

Abstract

This study aims to determine the effect of providing a combination of snails and coconut dregs as feed on the growth and protein content of Black soldier Fly (BSF) maggots. The method used is an experiment with a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments consist of: P1 (100% snails), P2 (75% snails: 25% coconut dregs), P3 (50%: 50%), P4 (25%: 75%), and P5 (100% coconut dregs). Maggot maintenance was carried out for 14 days with feeding carried out every 2 days in the morning at 10:00. The research data observed included Weight, Thickness, Length which were analyzed statistically using the ANOVA test and the test was continued with the Least Significant Difference (LSD) test, and the Kruskal wallis test if the data was not normal, temperature and humidity, Feed consumption, Specific growth rate (SGR), Waste reduction index (WRI), and Protein content and water content were analyzed using the automatic kjeldahl test. The results of the study showed that the provision of snail and coconut dregs feed had a very significant effect on the growth of maggots (P <0.05) both in weight and thickness, but had no significant effect (P>0.05) on the growth of maggot length. Treatment P1 (100% snail) gave the best results with an average weight of 0.09 g, a length of 13.4 mm, and the highest protein content of 27.49%. Treatment P5 (100% coconut dregs) showed the lowest results in all main parameters. It was concluded that snail feed was more optimal in supporting the growth and protein content of BSF maggots. The high animal protein content and soft texture are the main reasons, which show the potential of snails as a highly nutritious alternative feed for BSF maggot cultivation.

Abstract

Vincetoxicum villosum belongs to the Apocynaceae family. V. villosum is often used as a traditional medicine for treating jaundice, gallstones, kidney stones, hepatitis B, and liver diseases. This study aims to determine the metabolite profile and antioxidant activity of V. villosum to provide new information and serve as a reference for its safe use as a medicinal plant. The methods used to determine the metabolite profile involved GC-MS, and antioxidant activity was assessed using the DPPH method. GC-MS analysis showed that V. villosum leaf extract contains n-hexadecanoic acid, phytol, 9,12,15-octadecatrienoic acid (Z,Z,Z)-, and 2,4-di-tert-butylphenol which have potential antioxidant activity. The antioxidant activity in V. villosum leaves is classified as very weak, with  IC50 ranging 0.6 – 1.6 mg/mL, with the best antioxidant activity observed in polar solvents (ethanol extract) with a maceration time of 72 hours. The highest total phenol content was obtained using ethanol solvent with a maceration time of 72 hours, amounting to 416.17 mg GAE/g, and the highest total flavonoid content was obtained using ethyl acetate solvent with a maceration time of 24 hours, amounting to 168.78 mg QE/g

Abstract

The forest softshell turtle (Dogania subplana) is a species increasingly threatened by habitat destruction and overexploitation. This study aims to identify the acclimatization process of D. subplana in an artificial environment, specifically, an aquarium at the Turtle Learning Center (TLC). The research was conducted over 30 days from July to August 2024. Observations were made on daily behavior, body temperature, and health condition, individual biometric measurements, and environmental (abiotic) parameters. The results showed that daily behaviors such as feeding, basking, and hiding occurred regularly, indicating the species' ability to adapt to a new environment. The turtles experienced an increase in body weight, while growth in carapace length and width was very slow. The body temperature of D. subplana varied in accordance with the surrounding environmental temperature, reflecting its dependence on ambient conditions. Some individuals experienced minor health issues, such as fungal infections, but the majority remained active and healthy. Environmental factors such as temperature, humidity, pH, dissolved oxygen, total dissolved solids, and light intensity were within ranges conducive to acclimatization. These findings suggest that the aquarium at the TLC is quite effective as an ex situ conservation facility in supporting the adaptation process of D. subplana  outside its natural habitat.

Abstract

Exposure to mercury chloride (HgCl?) is known to induce oxidative stress, which negatively affects the hematological system, including a decrease in hemoglobin levels. This study aims to analyze the effect of honje fruit juice (Etlingera hemisphaerica), known for its high antioxidant content, on hemoglobin levels in mice (Mus musculus) exposed to mercury chloride. This study used an experimental method involving several groups of mice, namely group K1 (control), group K2 (given honje fruit juice), and group K3 (injected with mercury and given honje fruit juice). Hemoglobin levels were measured using a Sahli tube. The results showed that honje fruit juice significantly increased hemoglobin levels in mice exposed to mercury chloride compared to the control group. These findings indicate that the antioxidant content in honje fruit can help reduce the toxic effects of mercury chloride on the circulatory system. Therefore, honje fruit juice has the potential to be developed as a natural therapeutic agent in efforts to mitigate the toxic effects of mercury chloride.

Abstract

Kabau (Archidendron bubalinum (Jack) I.C. Nielsen) is a lesser-known legume native to Sumatra and surrounding regions that is widely used as food and traditional medicine, but its scientific and educational potential remains underexplored. This study presents a qualitative–descriptive literature review synthesizing ethnobotanical, phytochemical, pharmacological, and educational evidence on kabau, based on peer-reviewed national and international publications indexed in databases such as Scopus, PubMed, SpringerLink, Wiley Online Library, and Google Scholar. The review shows that kabau seeds and fruit pods contain diverse secondary metabolites, dominated by phenolics, flavonoids, terpenoids, fatty acids (e.g., linoleic and palmitic acids), and sulfur-containing amino acids related to djenkolic acid. These constituents underpin strong in vitro antioxidant activity and support preliminary evidence of antidiabetic, anti-hyperuricemic, and antimicrobial effects in enzyme-based assays and animal models. Ethnobotanical data from Bengkulu and other regions document kabau as a functional food, a remedy for metabolic and digestive disorders, and a component of local cultural identity. Drawing on this evidence, the article proposes a framework for integrating kabau into biology education as a contextual learning resource across topics such as plant morphology, ecology, ethnobotany, phytochemistry, health, and STEM-based inquiry. Integrating local biological resources like kabau is argued to promote scientific literacy, critical thinking, and sustainability awareness while strengthening students’ appreciation of local biodiversity. Further field, experimental, and design-based research is needed to standardize kabau-derived products and to evaluate their effectiveness and safety, as well as their impact on learning outcomes in science education.
