Abstract

β-CGTase (β-cyclodextrin glycosyl transferase) is an enzyme that converts starch into CD (cyclodextrin). The CD is a high-value oligosaccharide used for modifying food, textiles, chemicals, medicines, cosmetics, and biotechnology. This research aims to obtain isolates of β-CGTase producing bacteria from sweet potato plantation soil. Screening is carried out using Horikoshi media which contains the color indicators phenolphthalein and methyl orange. Bacteria producing β-CGTase will give a yellow hollow zone if they grow on this media. CGTase activity was measured using a UV-Vis spectrophotometer. Three isolates producing CGTase were obtained, coded BSP6A, BSP6B, and BSP6C, which had the characteristics of being Gram-positive, shaped like bacilli, produced spores, were motile, had a positive catalase test, and could ferment acid. These three isolates were able to produce the optimum CGTase enzyme if incubated for 18 and 24 hours at a temperature of 37°C and pH 10 and were able to convert starch into CD if incubated for 30 minutes at a temperature of 37°C and pH 7.

Abstract

Cyclodextrin glycosyltransferase (CGTase) is an extracellular enzyme produced by several microorganisms, particularly bacteria, that converts starch into cyclodextrin (CD). CD has various applications in fields such as food, textiles, pharmaceuticals, chemistry, and biotechnology. The objective of this study was to isolate b-CGTase-producing bacteria from soil in a potato plantation located in Kerinci, and to conduct their characterization. Screening was conducted using Horikoshi agar media with phenolphthalein and methyl orange color indicators. The results indicated that one isolate, coded CK-2, produced the optimum b-CGTase enzyme when incubated for 30 hours at 37 ºC and pH 10. The CGTase enzyme converted starch to CD when incubated for 60 minutes at 37 ºC and pH 7. The CK-2 isolate was identified as monobacilli Gram-positive bacteria, having spores, positive in the catalase test, and motile. The study concluded that the bacteria producing b-CGTase enzyme are found in the soil of potato plantations in Kerinci, which is believed to originate from the genus Bacillus sp.

Abstract

Seawater concentrate from Pamekasan is a product with high mineral content. The mineral content analysis of Pamekasan seawater concentrate was conducted using a comparative test of results from X-Ray Fluorescence Spectrometry (XRF) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This mineral content testing used a skin moisture device. The essential minerals found in Pamekasan seawater concentrate through analysis are Mg, Cl, K, Ca, Cr, Mn, Cu, and Zn. Statistical analysis results from XRF and ICP-OES on market products showed no significant difference in average results; however, there was a significant difference in average results in the samples. The most recommended method for analyzing seawater mineral concentrate from Pamekasan is ICP-OES due to its wider detection range and lower matrix interference.

Bromelain enzymes can be isolated from the peel, fruit, and stem of pineapple (Ananas comosus (L.) Merr). The purpose of this study was to obtain the concentration of bromelain enzymes from the peel and stem of Pineapple in inhibiting the growth of Staphylococcus aureus. Bromelain was isolated by extraction with phosphate buffer, purified with 60% of ammonium sulfate. Antibacterial activity tests of bromelain enzymes from the peel and stem of pineapple against Staphylococcus aureus were carried out in vitro using disc diffusion by measuring clear zones. The bromelain enzyme concentration used was 1%, 2%, 3% and 4% with chloramphenicol antibiotics as a positive control. The results showed that bromelain enzymes from peel and stem of pineapple at 4% concentration inhibited the growth of Staphylococcus aureus with inhibition zones of 19.23 mm and 18.30 mm respectively. The minimum inhibitory concentration of bromelain enzymes from peel and stem of pineapple was 1% with inhibition zones of 11.45 mm and 12.24 mm respectively. Bromelain enzymes from the peel and stem of pineapple provide the same activity in inhibiting the growth of Staphylococcus aureus bacteria.

Abstract

Background: Burns represent a condition of damaged or lost skin tissue due to high-temperature exposure. Oral therapy has limitations in penetrating hardened skin tissue, necessitating topical preparations such as gels that offer advantages in comfort, absorption capability, and ease of application. The stem of physic nut (Jatropha multifida L.) contains bioactive compounds including alkaloids, flavonoids, saponins, and tannins that may accelerate burn wound healing, particularly in its ethyl acetate fraction. Objective: This study aimed to formulate the ethyl acetate fraction of physic nut stem into a gel preparation and evaluate the effect of concentration variations on burn wound healing efficacy. Methods: Physic nut stems were extracted with 96% ethanol, then fractionated using n-hexane, ethyl acetate, and ethanol solvents. The ethyl acetate fraction was formulated into a hydrophilic gel at concentrations of 0.140%, 0.281%, and 0.421%. The gel preparations were evaluated through organoleptic tests, homogeneity, pH, spreadability, stability, irritation, and burn healing efficacy tests in rabbits. Results: Phytochemical screening revealed that the ethyl acetate fraction contained alkaloids, flavonoids, saponins, and tannins. All gel formulations met physical preparation requirements with skin-compatible pH (5.95-6.37). Formula F1 (0.140%) demonstrated optimal burn healing efficacy, equivalent to positive control (p > 0.05), and was topically safe (non-irritating). Conclusion: The ethyl acetate fraction of physic nut stem was successfully formulated into a stable and effective gel preparation for burn wound healing, with 0.140% as the optimal concentration. Further studies are required to examine toxicity and the mechanism of action of active compounds.

Abstract

Sa'adatuddaren Islamic Boarding School is one of the oldest Islamic boarding schools in Jambi City, located on the banks of the Batanghari River. One of the facilities provided by Islamic boarding schools is dormitories. Based on the survey conducted, problems were found, especially in female student dormitories. The dormitories are not kept clean, rubbish is strewn about, and female students use the Batanghari river water directly for bathing, defecating and washing. This condition causes health problems such as scabies, diarrhea, and others. Scabies is a major health problem at the Sa'adatuddaren Islamic Boarding School, Jambi Province. This is disturbing for students and dormitory supervisors, because it is difficult to apply PHBS to teenage students, at this age someone tends to be unstable and cannot control clean and healthy living habits, several supporting factors such as the condition of the Islamic boarding school, the students' busy routine and being far from their parents. Adolescence is the right age to form good habits, therefore MTs students are targets for socialization. Reminders are a solution for teenagers to create a scabies-free Islamic boarding school environment. The method involves conducting outreach, collecting data on students affected by scabies, treating infected students and implementing PHBS using Reminder stickers. The results of the outreach were an increase in knowledge, understanding and perspective of students at the Sa'adatuddaren Islamic boarding school in Jambi Province regarding scurvy and a healthy environmental cleanliness.
