Abstract

Earthworms (Lumbricus rubellus) are beneficial invertebrates that reduce waste, animal feed, and cosmetic raw material. The research was conducted at Ruyani Life Sciences Learning Resources (SBIH), Bengkulu (Ruyani et al., 2018), from September to November 2023. The design of this study adopted a Complete Randomized Design (RAL) consisting of five experimental groups with different feed comparisons (in %).Earthworm growth and development are optimized in their natural habitat, which includes temperatures ranging from 15℃ to 25℃, soil moisture and air availability between 15% and 30%, soil pH levels between 6.0 and 7.2, and the presence of organic matter for food. The study fed earthworms a diet consisting of tofu residues and cow dung in different proportions: (a) 100% tofu residues and 0% cow dung; (b) 75% tofu residues and 25% cow dung; (c) 50% tofu residues and 50% cow dung; and (d) 25% tofu residues and 75% cow dung. The research findings indicated that the ideal feed composition for maximizing earthworm biomass production is 25% tofu residues and 75% cow dung. Additionally, the most effective ratio of individual earthworms throughout a four-week maintenance period is 75% tofu residues and 25% cow dung.

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

Background: Fruit juice is highly needed nowadays due to its effectiveness as a source rich in antioxidants.Research Objective: This study aims to reduce glucose levels caused by the administration of HgCl₂, which is neurotoxic and cytotoxic, capable of damaging pancreatic β-cells that produce insulin. Etlingera hemisphaerica was utilized as a potential solution because it contains compounds such as terpenoids, flavonoids, phenols, and polyphenols that can lower glucose levels by maintaining the normal function of pancreatic β-cells. Method: This study applied a true experimental method with a pretest-posttest control group design, involving measurements taken before and after treatment. The subjects were divided into three test groups K1, K2, and K3 each consisting of three Mus musculus , with a total of nine mice. Results: The administration of Etlingera hemisphaerica Fruit Fresh Drink (MSBE) did not show a significant effect in reducing blood glucose levels in Mus musculus  induced with HgCl₂. Conclusion: The secondary metabolites contained in E. hemisphaerica  have not yet been able to repair or maintain blood glucose levels under conditions of damage caused by HgCl₂ exposure.

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.
