Abstract

The study aims to identify the main feed source for Apis nigrocincta through the analysis of polent morphology. The study uses explorative descriptive methods with qualitative and quantitative approaches. The focus of this study is the identification of feed source for endemic honeybees of Sulawesi, Apis nigrocincta through the analysis of polent morphology. Through the approach of polent morphology analysis, successfully identified 12 plant species from 9 families that could potentially be feed sources such as, Cucurbita maxima, Clematis viticella, Clematis montana, Pseuderanthemum tropurpureum, Cersicaria odorata, Solamun torvum, Solamun nigrum, Pine mercussii, Piper betle, Piper nigrum, and Galium aparine identification showed the presence of polyn diversity that supports the nutritional needs of bees, and emphasized the importance of local vegetation conservation to maintain the sustainability of the A. nigrocincta population. The results of the study showed that the polen has characteristics such as the polish unit, size, shape, shape on the P and E side, aperture type, as well as exin ornamentation. The polents collected by bees A. nigrocincta come from various types of plants, namely fruits, ornamental plants, vegetable plants, herb plants, and trees. This diversity reflects the flexibility of bees in choosing food sources based on availability in the surrounding environment. The results of the identification of the polymer samples showed that 12 species of plants that are the main feed source for A. nigrocincta bees are sourced from the polen. Each species has different flower characteristics, both in terms of shape and color. Polen diversity indicates that the environment around Jononunu Village has a rich ecosystem with different types of flowering plants.

Abstract

Heat shock protein 70 also known as HSP70 is a protein that regulates in response to stress factors such as heat, exercise, and others. The current research work used enzyme-linked immunosorbent assay (ELISA) to measure HSP70 levels in working horses on Sumbawa Island. Blood was taken through jugular venipuncture whereas saliva was collected non-invasively via cotton swab, both were analyzed with ELISA. The results indicated different expressions of HSP70; saliva shows a significantly higher level of HSP70 (52.07 ± 25.25 ng/mL) than serum (43.71 ± 34.83 ng/mL) from the same animal. The observed differences might indicate a better representation of acute stress by saliva due to physiological rapid turnover compared to serum, which reflects an integration of cumulative stress exposure. Our finding thus proves that double monitoring of both biological matrices offers complementary information in assessing stress in working horses while taking salivary HSP70 into account as especially promising for the in-field welfare monitoring due to its non-invasive collection and sensitivity to immediate stress conditions.

Abstract

This study aims to explore the effectiveness of handwashing soap made from cocoa pod husk extract in inhibiting the growth of pathogenic bacteria such as Salmonella typhi, Staphylococcus aureus, and Escherichia coli, which are common causes of various diseases. The extract used was a crude cocoa pod husk extract obtained through the maceration method using distilled water (aquadest) as the solvent. The extract was then formulated into soap at concentrations of 80%, 90%, and 100%. Antibacterial activity tests were carried out using the disk diffusion method based on CLSI standards to measure the inhibition zones against Escherichia coli, Staphylococcus aureus, and Salmonella typhi. The study used a completely randomized factorial design (3 x 3), involving three extract soap concentrations and three types of bacteria, each tested in three replications. Data were analyzed using Analysis of Variance (ANOVA) to determine the significance of differences among treatments. The inhibition zone measurements showed that at concentrations of 80%, 90%, and 100%, the zones for E. coli were 4.1 mm, 4.9 mm, and 6.3 mm respectively, classified as weak to moderate. For S. aureus, the inhibition zones were 7.3 mm at 80%, 11.30 mm at 90%, and 13.77 mm at 100%, which fall into the moderate to strong category. For S. typhi, the inhibition zones were 5.16 mm (80%), 6.3 mm (90%), and 8.81 mm (100%), categorized as moderate. It can be interpreted that cocoa pod husk extract soap showed the most effective antibacterial activity against S. aureus at 90% and 100% concentrations, while its inhibitory effect on E. coli and S. typhi was weaker to moderate. Biologically, the effectiveness of cocoa pod husk extract soap as a natural antibacterial agent is more optimal against Gram-positive bacteria such as S. aureus, whereas its effectiveness against Gram-negative bacteria like E. coli and S. typhi still needs to be optimized. The ANOVA test results showed a p-value < 0.05, indicating that the average inhibition zone results among the three bacterial types differed significantly. This confirms the potential of cocoa pod husk as a natural raw material for producing environmentally friendly antibacterial hand soap.

Abstract

This study evaluates the effects of NaOCl concentration and immersion time on contamination levels and viability of in vitro mangosteen seed explants, aiming to identify the optimal sterilization protocol. Conducted at YAHDI Tissue Culture Laboratory, Medan, Indonesia, a Randomized Complete Block Design tested three treatment combinations: (1) 15% and 10% NaOCl for 5 minutes, (2) 20% and 15% NaOCl for 15 minutes, and (3) 30% and 20% NaOCl for 25 minutes. After immersion, explants were rinsed three times with sterile distilled water. Observations spanned 12 MST, with data analyzed using ANOVA and Games-Howell post hoc tests; contamination sources were qualitatively described. Results showed the first combination had the lowest effectiveness, the second was better but suboptimal, while the third significantly delayed contamination and yielded the highest explant survival rate of 86.1%. The third treatment also prolonged the contamination-free period compared to others. Fungal and bacterial contaminants were predominant, highlighting the need for effective disinfectants against both. These findings indicate that the third combination is a promising sterilization protocol for mangosteen seed explants, especially for hard endocarp tissues prone to contamination.
