Efek Antiinflamasi Jus Bawang Putih terhadap Kadar C-Reactive Protein (CRP) pada Tikus Jantan Galur Sprague Dawley yang Diinduksi Karagenan
type: item
description: Garlic (Allium sativum L.) is known to contain bioactive compounds with pharmacological potential, including anti-inflammatory activity. Inflammation is characterized by an increase in the biomarker C-reactive protein (CRP), which is produced by the liver in response to inflammatory processes. This study aimed to evaluate the anti-inflammatory effect of garlic juice on CRP levels in male Sprague Dawley rats induced with carrageenan. An experimental design was applied using 24 male rats divided into six groups: normal control, negative control (Na-CMC 1%), positive control (diclofenac sodium 4.5 mg/kgBW), and treatment groups receiving garlic juice at doses of 300, 400, and 500 mg/kgBW. Inflammation was induced by 1% carrageenan injection, and CRP levels were measured using the CRP-latex method. The results showed that garlic juice significantly reduced CRP levels compared with the negative control (p<0.05). The 500 mg/kgBW dose produced the most optimal effect, approaching the efficacy of the positive control. Therefore, garlic juice has potential as a natural anti-inflammatory agent effective in reducing CRP levels.

type: item
description: Moringa (Moringa oleifera L.) is a member of the Moringaceae family that is rich in flavonoids and phenolics, especially in the leaves, with potential as an antioxidant and skin moisturizer. Serum is a preparation made with low viscosity so that it can deliver a thin film of active substances to the skin surface and has a high water content so that it can hydrate the skin. This study aims to optimize the formula of a face serum based on ethanol extract of moringa leaves. The extract was obtained using the maceration method and tested at concentrations of 2%, 4%, and 6%. The highest antioxidant activity was shown at a concentration of 6%, which was used as the optimal concentration in formulations with variations of 5%, 10%, and 15% glycerin. Antioxidant activity was tested in vitro using the DPPH method with UV-Vis spectrophotometry, while skin moisture was tested using a moisture skin analyzer. The results showed that all formulations met physical quality standards and had moderate to strong antioxidant activity with IC₅₀ values of F0 (36,772 ppm), F1 (26,966 ppm), F2 (25,300 ppm), and F3 (23,591 ppm). Increased concentrations of extract and glycerin were associated with decreased IC₅₀ values and increased moisturizing effects, with formula 4 producing the most optimal performance.

type: item
description: The use of sunscreen creams can protect the function of human skin structures from the negative effects of UV rays. This study aims to formulate sunscreen cream preparations with variations of polysorbate and sorbitan emulgators to determine the physical characteristics of cream preparations and determine the stability of sunscreen cream preparations containing titanium dioxide (TiO2) to SPF (Sun Protection Factor) values. This research uses laboratory experimental methods. The active ingredient used is TiO2, which is a physical blocker by reflecting UV radiation. Polysorbate and sorbitan are the emulgator combinations used in this study. Sunscreen cream preparations were formulated into four formulas by combining and varying the concentration of polysorbate and sorbitan emulgators. FI contained polysorbate 60 (3%) and sorbitan 60 (2%), FII polysorbate 80 (2.5%) and sorbitan 80 (2.5%), FIII polysorbate 60 (2.75%) and sorbitan 80 (2.25%), and FIV polysorbate 80 (3.25%) and sorbitan 60 (1.75%). Furthermore, the preparations were evaluated and tested for stability (cycling test,) as well as effectiveness determination tests (SPF, and %TE). The results showed that different combinations and variations in the concentration of polysorbate and sorbitan emulgators in the four formulas had an influence on the physical characteristics and stability of the preparation. And the results of the determination of the effectiveness of sunscreen cream have an influence of UV exposure on the in vitro effectiveness of sunscreen cream (SPF, and %TE).

type: item
description: Exposure to ultraviolet rays at a certain level cannot be accepted by human skin. Objective: This study aims to see the potential value of the Sun Protection Factor (SPF) of green betel leaves (Piper betle L.) by finding good stability using stearic acid. Methods: This study was conducted with a qualitative approach with a laboratory experimental method. Data collection directly from the laboratory to determine whether there is sunscreen activity in green betel leaf extract (Piper betle L.) to see if there is a difference in the effect of stearic acid concentration on the stability of green betel leaf extract sunscreen cream (Piper betle L.). Results: The results obtained are that green betel leaf extract (Piper betle L.) has sunscreen activity with the higher the concentration of the extract, the higher the Sun Protection Factor (SPF) value. This can be proven by the results of data processing obtained, every 1% increase in concentration value. Then the SPF value increases by 0.21. The results of the stability test showed stable results with organoleptic consistency, pH, and homogeneity, and spreadability. After being formulated, the sunscreen cream has a Sun Protection Factor (SPF) value, the higher the concentration of stearic acid, the lower the SPF value, this can be proven by the results of data processing with the addition of 1% concentration value. Conclusion: The Sun Protection Factor (SPF) value decreases by -0.900 but the stability of the preparation shows good results. This study suggests that it is necessary to test the antioxidant levels in green betel leaf extract (Piper betle L.).

description: A famous traditional herbal cure created from natural materials, turmeric and tamarind herbal medicine (jamu turmeric tamarind) is now readily available in powder form. The purpose of this study is to evaluate the safety and quality of powdered turmeric and tamarind herbal medicine by looking at factors including water content, total phenolic content, and microbiological contamination. Six brands of commercially available powdered turmeric and tamarind herbal medicine were the subject of an experimental laboratory investigation. The Folin–Ciocalteu method was used to determine the total phenolic content, the gravimetric technique was used to measure the water content, and the pour plate method was used to conduct the Yeast Mold Count (YMC) and Total Plate Count (TPC) assays. The findings indicated that all samples had AKK values ​​between <1 and 1.7 × 10¹ cfu/g and ALT values ​​between <1 and 1.2 × 10⁴ cfu/g, both of which were below the upper limit established by BPOM Regulation Number 29 of 2023. Significant variations were observed in the total phenolic levels among the samples; the maximum value was 121.03 mg GAE/g, while other samples had extremely low values. All of the samples met the quality requirements for natural medical powder formulations since their water contents ranged from 0.62 to 7.20%, which is less than 10%. The analyzed powdered turmeric and tamarind herbal medicine satisfies microbiological safety and quality criteria, has an acceptable water content, and exhibits a range of bioactive potential, according to these findings.

Analisis Pengaruh Faktor Sosial Ekonomi terhadap Kepatuhan Pasien dalam Penggunaan Antibiotika Secara Oral di Puskesmas X Kota Depok
type: item
description: The inappropriate use of antibiotics is one of the main factors contributing to antimicrobial resistance (AMR), which significantly increases global morbidity and mortality rates. Patient adherence to antibiotic regimens plays a crucial role in preventing the development of resistance. Socioeconomic factors, such as educational level, occupation, and income, are suspected to influence adherence levels. This study aims to analyze the impact of socioeconomic factors on adherence to oral antibiotic use at Puskesmas X in Depok City. The results indicate that socioeconomic factors (education, occupation, and income) collectively have a significant effect on adherence to oral antibiotic use, contributing 10.8% to the variance in adherence, while the remaining 89.2% is influenced by other unexamined factors. An ANOVA (F-test) yielded a significance value of 0.011 (< 0.05), thereby supporting the general hypothesis (H1). Further analysis using partial t-tests revealed that educational level was the most influential factor, with a significance value of 0.052, close to the α threshold of 0.05. This finding suggests that higher educational attainment enhances individuals’ ability to understand medical information and follow antibiotic usage instructions, thereby improving adherence. Conversely, occupation (α = 0.759) and income level (α = 0.122) did not demonstrate a significant influence on adherence to oral antibiotic use
