Abstract

This study aimed to determine the antibacterial activity of Lo’i keta solution and methanol extract against the growth of Staphylococcus epidermidis and Pseudomonas aeruginosa. The research employed a true experimental design using a Posttest Only Control Group Design with the well diffusion method. A total of 80 samples were divided into 20 treatment groups with concentrations of 25%, 50%, 75%, and 100%, along with a positive control (ciprofloxacin) and a negative control (distilled water). GC-MS analysis revealed nine bioactive compounds in the methanol extract of Lo’i keta. The results showed that the Lo’i keta solution inhibited the growth of Staphylococcus epidermidis with inhibition zones ranging from 15–24 mm, while the methanol extract produced larger inhibition zones of 18–32 mm. Against Pseudomonas aeruginosa, only the methanol extract demonstrated antibacterial activity with inhibition zones of 13–17 mm, whereas the solution showed no inhibitory effect. The Kruskal-Wallis test indicated significant differences among the treatment groups. In conclusion, both the Lo’i keta solution and the methanol extract were effective in inhibiting the growth of Staphylococcus epidermidis, while antibacterial activity against Pseudomonas aeruginosa was observed only in the methanol extract. Lo’i keta demonstrates potential to be developed as a traditional medicine-based antibacterial alternative.

Abstract

This study aimed to determine the pupicidal activity of ethanol extract from bilimbi ( Averrhoa bilimbi L.) leaves against Ae. aegypti pupal mortality. A true experimental design was employed to evaluate the toxicity of various ethanol extract concentrations against pupae over treatment periods of 24 and 48 hours. Mortality rates were recorded and calculated using the WHO mortality formula, and lethal concentrations (LC50 and LC90) were determined via probit analysis to identify concentrations causing 50% and 90% pupal mortality. The results showed that the ethanol extract exhibited dose-dependent pupicidal activity, with the highest mortality observed at 4% concentration, achieving 97.33% mortality after 48 hours. The LC50 values were 2.378% at 24 hours and 1.425% at 48 hours, indicating an increased effectiveness over time. The findings suggest that the ethanol extract of bilimbi leaves has potential as a natural pupicide, offering an eco-friendly alternative for controlling Ae. aegypti populations. Further studies are needed to optimize formulation and field application for sustainable mosquito vector management.

Abstract

This study aims to evaluate the antioxidant potential of bioactive compounds from Adenostemma lavenia in targeting interleukin-6 (IL-6) associated with pulmonary sepsis. Phytochemicals from Adenostemma lavenia leaves were identified using GC-MS, and ten bioactive compounds with potential antioxidant activity were selected. These compounds underwent further in silico evaluation, including drug-likeness screening, biological activity prediction, pharmacokinetic and toxicity analysis, and molecular docking against interleukin-6 (PDB ID: 8J6F). Among them, stigmasterol showed the highest docking score of –8.1 kcal/mol and a PASS prediction probability (Pa) of 0.867 for antioxidant activity. Half of them fully complied with drug-likeness criteria. Among these, D-Allose, 2,4-Di-tert-butylphenol, and Phytol demonstrated the highest predicted antioxidant activity. Toxicity evaluations revealed a generally safe profile, with minimal nephrotoxicity in two compounds. Notably, Phytol exhibited the closest similarity in binding residues to the native ligand of IL-6, suggesting a strong binding orientation and promising therapeutic value. The in silico findings highlight Phytol and other antioxidant-rich phytoconstituents of A. lavenia as promising agents targeting IL-6, supporting their potential use as adjunct therapies for oxidative stress-related conditions such as pulmonary sepsis. These results contribute to the scientific understanding of natural antioxidants in inflammation control and warrant further validation through in vitro and in vivo studies.

Abstract

This study aims to determine the management of Madura cows, grades 1 and 2, based on local wisdom in the breeding source area of Waru Subdistrict, Pamekasan Regency. The method used was a case study. Data were obtained through direct interviews with 36 farmers who met the following criteria: keeping at least 2 Madura cows of grade 1 and 2 females, cattle aged 24-36 months, in good health, who had given birth, and who were not pregnant. Data were analyzed using the Chi-Square Test and was analyzed descriptively.. The results showed that the breeding management aspects of feed, housing, and mating systems for grade 1 and 2 cows were not significantly different (P>0.05). However, on average, grade 1 breeding management tended to be better than grade 2. Average forage feeding was 29.89±1.65 kg/head/day (grade 1) and 25.06±1.81 kg/head/day (grade 2). The mean supplementary feeding of Tajin was 3.11 kg/head/day (grade 1) and 2.06 kg/head/day (grade 2). Grade 1 (88.89%) and grade 2 (72.22%) farmers used wood-based stage cages with tile roofs and areas, as specified by SNI. Natural mating was the leading choice of grade 1 (68.42%) and grade 2 (64.71%) breeders. In comparison, Artificial Insemination was the leading choice of grade 1 (31.58%) and grade 2 (35.29%) breeders. The study concluded that the components of grade 1 and 2 breeding management, based on local wisdom, are similar; however, there are differences in the quantity of treatment. The forage feed management aspect of grade 1 was 16.15% higher than grade 2. Supplementary feed Tajin grade 1 was 33.76% more than grade 2. The majority of grade 1 and 2 farmers used wood-based stage cages with tile roofs, and the area was by SNI. The ratio of the natural breeding system in grade 1 and grade 2 was 7.68%, and the AI was 19.99%.

Abstract

This study aimed to analyze the phenotypic variation and morphometric profiles of female Madura cattle across different grades in the breeding source area of Pamekasan Regency. A case study method was employed using a purposive sampling technique, involving 120 female Madura cattle aged 30–36 months, healthy, and non-pregnant. Data on qualitative phenotypic traits and morphometric profiles (shoulder height, body length, and chest girth) were analyzed using Chi-square and Q–Q Plot tests. The results showed that the phenotypic variation of female Madura cattle across grades did not differ significantly from the Indonesian National Standard (SNI) for Madura cattle (P > 0.05). The percentages of phenotypic conformity to the SNI in grades 1, 2, and 3 were 96.67%, 95.24%, and 93.75%, respectively, while non-conformities were 3.33%, 4.76%, and 6.75%. Morphometric profiles were also consistent with the SNI without significant differences (P > 0.05). However, the mean morphometric values tended to be slightly higher—by 1.72–3.69%—compared to the SNI standard. The Q–Q Plot analysis indicated that morphometric data of female Madura cattle across all grades were normally distributed, with grade 1 showing greater variation than grades 2 and 3.

Abstract

Forests store biomass and carbon in the form of living trees, forest floor detritus (e.g. litter falls), soil and wood products. This study describes inventory results of the above ground biomass of teak (Tectona grandis L.f.). By determining the site condition and developing allometric method, the inventory was designed to estimate the potential of above ground biomass of teak. This study aims to determine the characteristics or site qualities, carbon stock and find out whether the characteristics of the soil has a high or low correlation to the carbon stored in teak forest in Taman Wisata Alam Camplong, East Nusa Tenggara Province. Carbon stored in teak forests are 45.53 ton/ha and 104.35 ton/ha for IV and V age classes, respectively. The correlation between soil characteristics and carbon stock is obtained that the P and K soil has a positive correlation to carbon stock in the teak forest. The equation model for the relationship between growing conditions and aboveground carbon stocks is Y=25.182-4.149X1-172.231X2 + 2.046X3 + 32.711X4 + 0.297X5-28.330X6-1.746X7 +0.171X8.

Abstract

This study aims to describe the obstacles faced by biology teachers at the senior high school (SMA) level in South Palu District in implementing the Independent Curriculum. The method used was descriptive qualitative, with biology teachers from two schools in South Palu District as subjects. The research instruments were interview sheets and questionnaires. The questionnaires were analyzed using an average score calculation to determine the category of obstacles, while the interview data were analyzed qualitatively through data reduction, data presentation, and conclusion drawing. The results of the questionnaire analysis showed that teacher obstacles ranged from low to very low. Among the three aspects, implementation had a relatively greater level of obstacles than planning and assessment, but remained in the low category, while planning and assessment were both in the very low category. Interviews supported these findings, namely that teachers still relied on training modules and experienced difficulties in adapting assessments to student characteristics, as well as facing limitations in facilities and technology. In general, it can be concluded that the obstacles faced by Biology teachers in implementing the Independent Curriculum in South Palu District are in the low and very low categories, but mentoring, competency strengthening, and infrastructure support are still needed so that curriculum implementation can run optimally.
