Honey is natural liquid produced by honey bees. In reality, the quality can be reduced if the storage is not done properly. Diastase enzyme activity is one of the important honey quality parameters. The purpose of this research was to determine the quality of honey that was influenced by storage temperature on the activity of the diastase enzyme using Spectrophotometry method. Samples were obtained from the beekeeping area of East Jakarta. The results showed that, storage temperature greatly affects the quality of honey. Diastase enzyme activity was significantly different in each treatment at storage temeprature (P-Value < 0,05). Honey’s best storage temperature was at room temperature (26oC) compared to hot (50oC) and cold (±5oC) temperatures.

Sandoricum koetjape belongs to the family Meliaceae which is known to have antioxidant activity. Natives of Betawi use stem of S. koetjape for the treatment of helminthiasis meanwhile leaf of S. koetjape was used for the treatment of fever. Stem and leaf of that plant were tested for phytochemical and total phenolics content. Phytochemical screening of plants extracts revealed the presence of quinon. Quantitative determination of total phenolics of methanol and chloride acid extract was carried out using colorimetric methods. The mean total phenolics content was found to be 1.4155 mg/g and 3.1469 mg/g for stem and leaf respectively (ANOVA, p=0.000). There is significant difference in total phenolics content between the stem and leaf of Sandoricum koetjape.

Background: Plaque is a soft deposit attached to the teeth consisting of various types of microorganisms from saliva and food waste. Plaque cannot be seen because it is transparent, like the color of translucent white glass. The way to see plaque is to use a contrast material such as a dye (red/purple) in the form of a liquid or gel called a disclosing solution. It is usually found in gel and liquid form. But in use in humans there are many shortcomings because they are expensive, quite expensive and often contain harmful chemicals. One of the herbal plants that can be used as an alternative material as a disclosing solution is Rosella (Hibiscus sabdariffa L.) which can be used for its properties in the field of Prevention of Dental and Oral Diseases and has antibacterial and remineralizing effects. Methods: This research is an experimental study on the development of Rosella Flower Extract (Hibiscus sabdariffa L.) in the form of a gel in disclosing solution. The research was carried out from June to August 2021 at the Pharmacognosy Laboratory, Department of Pharmacy and Food Analysis, Health Polytechnic of Jakarta II and Dental Health Laboratory, Health Polytechnic of Jakarta I. Disclosing solution prepared from dried Rosella Flowers (Hibiscus sabdariffa L.) was obtained as much as 1000 grams. from the Research Institute for Spices and Medicinal Plants, Bogor. Hedonic testing was carried out on 34 students of the Department of Dental Health, Health Polytechnic of Jakarta I. Results: The disclosing solution preparation in the form of a gel from rosella flower extract had good organoleptic test results. The expected red color corresponding to the color of the disclosing solution is at a concentration of 70%. The average pH of the disclosing solution in the form of a gel was 4.95. The average dispersion of the gel preparation is 5.7. 5. The average adhesion of gel preparations at all concentrations is 1.44 seconds. The hedonic test was obtained that most of the respondents had a neutral opinion on all disclosing gel preparations. Conclusion: The preparation of Roselle Flower Extract Gel (Hibiscus sabdariffa L) can be used as an alternative disclosing solution

Anas Gilang Pratama, “Analysis of Total Plate Count, Yeast, and Mould Count, Salmonella spp., Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Shigella spp. on Traditional Medicines” under the guidance of Silvester Maximus Tulandi, S.Farm., M.Sc., and Ruth Elenora Kristanty, M.Farm., Apt., 2019. Traditional medicines can be contaminated by bacteria starting from the raw material process, during production, and at the time of storage. The analysis of total plate count, yeast, and mould count on traditional medicines was done at the Microbiology Laboratory of National Agency of Drug and Food Control in Jakarta by using five types of bacteria. This work was based on microbiological test parameters on traditional medicines through several stages: homogenization, enrichment, isolation, and biochemical tests. Based on the results, the samples fulfilled the requirements on Analysis of Total Plate Count, Yeast, and Mould Count, Salmonella sp, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Shigella spp. according to the Regulation of the Head of the National Agency of Drug and Food Control No.12/2014.
