The Effect of Alginate-Chitosan/Quaternary Chitosan Concentration on The Release of Propolis (Tetragonula Spp.) in Hydrogel Wound Dressings
type: item
description: The increasing incidence of acute and chronic wounds globally requires the development of effective wound dressings. This study aims to formulate and analyze the release profile of propolis extract (Tetragonula spp.), which has potential biological activity for wound healing, from a hydrogel wound dressing (HWD) based on alginate-chitosan/quaternary chitosan biocomposite as a delivery system that can control its release. Propolis extract, which has been tested positive for alkaloids, flavonoids, tannins, and steroids/triterpenoids, was formulated into four HWD formulas (F1-F4) with varying ratios using the solvent casting method. The results of the release test in PBS medium at pH 7.4 at 37 C for 48 hours showed that all formulas produced a gradual release. The results of the One-Way ANOVA test on the final cumulative release showed no statistically significant differences (p>0.05). However, descriptively, Formula F2 (4% alginate-8% quaternary chitosan) showed the highest release percentage (99.85%) with the most stable rate, followed by F4 (98.71%), while F3 with high chitosan showed the lowest percentage (86.65%). The best release kinetics analysis followed the Higuchi model (R² ≥ 0.95), indicating that the release mechanism was controlled by diffusion. It was concluded that variations in the alginate and chitosan/quaternary chitosan ratios affected the release pattern and rate, and Formula F2 with a balanced ratio produced an optimal controlled release profile, making it the most ideal candidate for further development as a therapeutic hydrogel wound dressing.

Comparison of Lead (Pb) Content Analysis Using Atomic Absorption Spectrophotometry with Wet and Dry Destruction Methods in Body Lotion Preparations in Semarang City
type: item
description: Many body lotions are found in circulation without a BPOM RI registration number, which can raise concerns about lead metal contamination. The lead metal content in body lotion can be sourced from the raw material, namely water. Lead metal levels in water range from 0,011 mg/L to 0,076 mg/L. Determination of lead levels uses an Atomic Absorption Spectrophotometry instrument. The requirement for analysis using Atomic Absorption Spectrophotometry is that the sample must be in solution form, so a destruction process is necessary because the body lotion sample is in semi-solid form. This study aims to compare two commonly used destruction methods, namely wet and dry destruction. The methodology in this study consists of qualitative analysis, method validation, and quantitative analysis. The test results with qualitative analysis showed negative lead metal content. The results of the Atomic Absorption Spectrophotometry method validation were: linearity (R2) of 0,9999; LoD of 0,024 mg/L; LoQ of 0,080 mg/L; precision (%RSD) of 0,61%; accuracy (%Recovery) of 100,09% with quantitative results of the percentage of wet digestion sample content, results were: 1,2264 ± 2,96%; 1,7687 ± 4,24%; 1,5036 ± 3,75%; 1,1807 ± 2,92%; and 1,5606 ± 3,88%. This can happen because the wet destruction method is better to use than the dry destruction method which can be seen from the %Recovery.

Antidiabetic and Antihyperuricemic Activities of Salak Madu (Salacca edulis Reinw) Peel Extract in Alloxan- and High-Purine Diet-Induced Mice
type: item
description: Diabetes mellitus (DM) is a chronic metabolic disorder characterized by impaired carbohydrate, lipid, and protein metabolism. Hyperuricemia is a condition in which serum uric‑acid levels exceed normal values, namely > 7.0 mg/dL in men and > 6.0 mg/dL in women. Both antidiabetic and antihyperuricemic therapies can be administered pharmacologically and non‑pharmacologically; however, synthetic drugs often produce undesirable side effects. Concerns regarding these adverse effects have led many people to favour herbal remedies that are perceived as safer, one of which is the Salak Madu fruit. Salak Madu (Salacca edulis Reinw.), an emerging premium variety cultivated in Sleman, Yogyakarta, is rich in flavonoids with potential antihyperglycaemic and antihyperuricaemic properties. The present study evaluated the antidiabetic and antihyperuricemic activities of Salak Madu peel extract in vivo using alloxan‑induced and high‑purine‑diet mouse models. Mice were observed over 14 days and treated orally with peel extract at doses of 100, 200, and 400 mg/kg body weight (BW). On day 14, the 100 and 200 mg/kg BW doses produced significant reductions in blood‑glucose levels (P < 0.05), indicating a marked antihyperglycaemic effect in hyperglycaemic mice. For serum uric‑acid reduction, significant effects were observed on day 7 at doses of 200 and 400 mg/kg BW (P < 0.05), demonstrating a pronounced antihyperuricemic action in hyperuricemic mice.

This study utilizes the betacyanin content in beetroot (Beta vulgaris L.)—a phenolic compound with photoprotective properties that can counteract UV free radicals. This study applies nanotechnology through the formulation of beetroot extract nanoparticles to optimize sunscreen activity. Aim: This study aims to evaluate and compare the sunscreen activity between lip balm formulations containing beetroot extract nanoparticles and beetroot extract lip balm formulations, as well as to determine the extent of the effectiveness of nanoparticle-based lip balm in providing protection against UV rays. Materials and Methods: This study extracted beetroot (Beta vulgaris L.) using the maceration method with 96% ethanol, yielding a concentrated extract (yield 34%) with a dark red color. Results: Phytochemical analysis revealed the presence of flavonoids, phenolics (20 mg GAE/g), tannins, and alkaloids in beetroot. The nanoparticle extract was successfully formulated with a size of 1.05 nm (PDI 0.403) and a zeta potential of -21.0 mV. Among the seven lip balm formulations, F6 (30% nanoextract) demonstrated the best performance with an SPF of 25.25 (ultra category), %Te of 0.26%, and %Tp of 0.61%, as well as optimal physical stability (homogeneous, melting point 70°C, pH 4.5–6.5). The nanoextract formulas (F4–F6) significantly outperformed conventional extracts (F1–F3) in sunscreen activity, demonstrating the effectiveness of nanotechnology in enhancing UV protection. Conclusion: These findings demonstrate that beetroot nanoparticle extracts have potential as an effective and safe natural sunscreen lip balm for lip protection

Optimisation of SSG (Sodium Starch Glycolate) and Avicel PH 102 in the Formula of Orally Disintegrating Acetaminophen Tablets by Simplex Lattice Design Method
type: item
description: Background: ODT acetaminophen tablets are an alternative drug therapy for patients who have difficulty in swallowing tablets or capsules. Additional ingredients that play an important role in the ODT tablet formula are disintegrants. The disintegrants used in this study were avicel ph 102 and SSG. The use of disintegrants can help increase the dissolution rate and accelerate the destruction time. Aim: The purpose of this study was to determine the optimum formula of ODT acetaminophen tablets and analyse the effect of SSG and avicel ph 102 on dissolution and disintegration time. Material and Methods: Determination of acetaminophen ODT tablet formula was carried out running in design expert software with the simplex latice design method. Preparation of ODT acetaminophen tablets was carried out by direct felting. The evaluation of ODT acetaminophen tablets was IPC physical evaluation, determination of content, and dissolution. Determination of the optimum formula was done by simplex latice design method. Results: The results showed that all ODT acetaminophen tablet formulas fulfilled all the requirements of the IPC test, physical evaluation, dissolution, and determination of levels according to the Pharmacopoeia VI edition standards. Formula 3 produced the fastest disintegration time of 3 minutes, but the dissolution rate of 100% was reached in the 15th minute. It is suspected that gel formation in the SSG swelling mechanism slowed down the dissolution rate. While formulas 1, 2, and 4 which have a longer disintegration time reached >80% dissolution in the 10th minute. Conclusion: The optimum formula results with the simplex latice design method were SSG 8% and avicel ph 102 7%. Avicel ph 102 and SSG had the effect of accelerating the destruction time and slowing down the dissolution rate.

The Effect of Ethanolic Extract of Bangle Rhizome (Zingiber purpureum Roxb.) on Reducing Blood Sugar Levels in Hyperglycemic Mice: In vivo and In silico Studies
type: item
description: Diabetes mellitus (DM) is a metabolic disease in which blood sugar levels are uncontrolled. Type 2 diabetes mellitus is uncontrolled blood sugar levels that occur due to insulin resistance or reduced body sensitivity to insulin. Treatment of type 2 diabetes mellitus, pharmacologically, uses oral antihyperglycemic drugs and injectable antihyperglycemic drugs. Although effective, antidiabetic drugs often cause adverse side effects. Indonesian people are concerned about synthetic drugs because of the potential side effects caused so that people are encouraged to look for more natural or herbal alternative treatments that are believed to have antidiabetic activity, one of which is ginger. Bangle (Zingiber purpureum Roxb.) is one of the plants that belongs to the zingiberaceae or ginger family. Bangle rhizome has a major compound of curcumin of 2,633% w/w and phenylbutanoid which has antioxidant, anti-inflammatory, and AMPK (AMP-activated protein kinase) agonist activity. With this activity, the antidiabetic potential of bangle rhizome was tested in vivo using alloxan-induced hyperglycemic mice, observed in 14 days with bangle rhizome extract doses of 100mg/kgBW, 200mg/kgBW, 400mg/kgBW, and in silico to determine compounds that have antidiabetic activity. The results obtained from the in vivo test for reducing blood sugar on days 7 and 14 had a significance value of 0.383 (p>0.05) and 0.253 (p>0.05) which means that the administration of bangle rhizome extract did not have a significant effect on reducing blood sugar in hyperglycemic male mice. The in silico test conducted was in line with the in vivo results where bangle rhizome extract had greater potential for anticancer, anti-inflammatory, and fat metabolism activities. The PASS Online results did not show any activity related to insulin sensitivity or alpha glucosidase inhibitor activity.

Validation Study of the Method of Analysis of Fe (II) Levels in Blood Addition Tablet Preparations by Wet Destruction and Dry Destruction Methods by UV-Vis Spectrophotometry
type: item
description: Iron is one of the micro minerals needed in the human body. One effort to meet iron needs can be done by consuming blood supplement tablets that contain iron. The iron content contained in blood supplement tablets needs to be known by carrying out quality testing to ensure that the preparation contains the specified ingredients and quantities. The UV-Vis spectrophotometer is an alternative method for determining iron levels because it has lower operating costs and is simpler but has high sensitivity. Determining the iron content to be analyzed requires a complexing agent to form colored compounds. The complexing compound often used in this research is phenantorline. The requirement for metal analysis using a UV-Vis Spectrophotometer is that the sample must be in solution form so a digestion process needs to be carried out. Destruction is divided into two, namely dry and wet destruction. This study aims to compare two digestion methods that are commonly used, namely wet digestion and dry digestion in determining Fe (II) levels in blood supplement tablets. In this research, method validation will also be carried out which aims to show that the testing procedures used obtain the expected results consistently and continuously. Validation of analytical methods carried out includes linearity test parameters, detection limit tests, quantitation limit tests, accuracy tests and precision tests. . Linearity is indicated by R2 of 0.9986; detection limit of 1.10 mg/L; quantitation limit of 3.62 mg/L; accuracy of dry digestion and wet digestion between 80-120%; and precision of dry digestion and wet digestion as indicated by an RSD percentage below 2%. Quantitative test results showed that the percentage levels of blood added tablet samples from wet digestion and dry digestion were 91.52% respectively; 100.09%; 96.15%; 100.96%; 100.67%. and 93.39%; 108.29%; 99.47%; 93.47%; and 92.57%.

It is known that excessive & longterm use of sodium cyclamate can cause adverse health effects. Currently, the standard method used to detect the presence of cyclamate refers to the precipitation method of SNI 01-2893. However, the level of sensitivity of the method is unknown. This study aims to determine the sensitivity of the precipitation method of SNI 01-2893, as well as to optimize reagents that have better sensitivity to be used as a reference for cyclamate precipitation reagents and applied to measure cyclamate in jamu. The determination the method’s sensitivity is based on the smallest concentration of cyclamate standard that can be detected by the method. Optimization of the precipitation reagent was carried out on 6 variations of precipitation reagent concentration to obtain a new formula that has a better sensitivity than the SNI 01-2893 method. Jamu samples were tested using the new optimized reagent formula. The result showed the detection limit of the of SNI 01-2893 method is 5 ppm. Optimization of the precipitation reagent formula with the composition of HCl 10%, BaCl2 10%, and NaNO2 20% showed as the highest sensitivity. It was marked by an increase in the amount of precipitate formed and had a detection limit of up to 0.9 ppm. Based on testing using the new reagent, 9 out of 10 jamu samples were positive for cyclamate. The cyclamate levels of the 9 jamu samples were measured using the spectrophotometric method, the results showed cyclamate levels are in the range of 4.3 - 6.32 mg/kg sample and meeting BPOM requirements.
