Comparing the Financial Burden of Colorectal Cancer Chemotherapy on Indonesian Healthcare Insurance (JKN) Coverage: A Study in East Kalimantan
type: item
description: Background: Colorectal cancer (CRC) constitutes a major public health burden in Indonesia. Chemotherapy remains the primary treatment for advanced CRC but creates substantial financial pressure on patients, hospitals, and the National Health Insurance (JKN) system. Although reimbursement is provided through the Indonesia Case Base Groups (INA-CBGs), differences between actual costs and tariff rates have been reported. Objective: This study assessed the financial burden of chemotherapy for stage III and metastatic CRC and its alignment with JKN reimbursement in a government referral hospital in Kalimantan. Methods: A retrospective cross-sectional study was conducted at Abdoel Wahab Sjahranie Regional General Hospital, Samarinda, using medical records from January-June 2024. A total of 129 chemotherapy visits were analyzed. Direct medical costs were compared with INA-CBG claims using descriptive statistics and the Mann–Whitney U test. Results: FOLFIRI was the most frequently administered regimen (71%). The total chemotherapy cost was Rp590,674,630, with a mean of Rp4,578,873 per visit. Pharmaceutical costs accounted for 56.58% of total expenditures. Actual costs were adequately covered by JKN, resulting in a positive variance of Rp1,314,544 per visit. Conclusion: INA-CBG reimbursement adequately covered CRC chemotherapy costs, although continued evaluation of JKN financing sustainability is warranted.

type: item
description: Nutraceutical is food for health with functions of preventive, promotive, rehabilitation, aesthetic, intelligence to curative. Nutraceuticals as food products can have a contemporary value, which is a trend or extraordinary circumstance that attracts consumers because of its function as a supplement, functional food, medical food, and genetically engineered food so that it penetrates the world market without limits. Nutraceuticals that are contemporary make it easy to achieve the goals of health care by using the "nutraceuticals" approach because the client wishes to himself with a high level of confidence in the benefits of the product for health and therefore uses it. Potential compound for nutraceuticals is secondary metabolites because it has multipotential for health, but specific to certain functions. Secondary metabolites, generally sourced from low plants and animals, because these biological groups do not have a perfect secretion system so that metabolites resulting from secondary metabolism are stored in cells and tissues properly, with several functions, among others, for defense and attractiveness of the biological. Some of the classes and compounds of plant secondary metabolites that are known to have potential for nutraceuticals are Terpenoids, Terpenoids non-Carotenoids, Polyphenolics, Phenolic Acids, Non-Flavonoid Polyphenolics, Glucosinolates, Thiosulphinates, Phytosterols, Anthraquinones, Glucosamines, Octacosanolines, Characticines, Chines) Pectin, Pigments, Tocotrienols and Tocopherols, Ubiquinon and ?-Lipoic Acid. Furthermore, some contemporary nutraceuticals are Spiruline, Broccoli, Aloe Vera Gel and Aloe Juice, Soyfoods, Omega-3- Fatty Acids, Pomegranate Juice, Walnuts, and Organic Mushroom Nutrace.

Toxicity Prediction of Bioactive β-Sitosterol from Saw Palmetto (Serenoa repens)
type: item
description: β-sitosterol is one of the major bioactive compounds found in Serenoa repens (Saw Palmetto) that has been widely studied for its potential therapeutic effects, particularly in prostate disorders. This study aimed to evaluate the toxicity profile of β-sitosterol using an in silico approach through the ProTox-III platform. Toxicity predictions included organ toxicity and toxicity endpoints. The results showed that β-sitosterol was predicted to be inactive for hepatotoxicity (0.87), nephrotoxicity (0.89), and cardiotoxicity (0.85), indicating a low risk to major organs. Additionally, carcinogenicity (0.60), mutagenicity (0.98), cytotoxicity (0.94), and clinical toxicity (0.52) were also predicted to be inactive, suggesting a favorable safety profile. However, β-sitosterol demonstrated active predictions for neurotoxicity (0.54), respiratory toxicity (0.82), immunotoxicity (0.99), blood-brain barrier penetration (0.91), and nutritional toxicity (0.66), indicating potential risks that require further investigation. Overall, the findings suggest that β-sitosterol has a generally safe toxicity profile but may pose moderate risks in specific toxicity parameters. Further experimental validation through in vitro and in vivo studies is recommended to confirm these findings and support the safe therapeutic use of β-sitosterol.

Potential Molecular Targets of α-Linolenic Acid from Green Purslane (Portulaca oleracea) Through SwissTargetPrediction Analysis
type: item
description: α-Linolenic acid is an essential omega-3 fatty acid widely found in medicinal plants, including Portulaca oleracea, and is known for its diverse pharmacological activities. However, the molecular targets underlying its biological effects remain insufficiently explored. This study aimed to predict the potential molecular targets of α-linolenic acid using an in silico approach. The molecular structure of α-linolenic acid was obtained in the form of SMILES from PubChem, followed by target prediction using SwissTargetPrediction. The analysis revealed several key targets, including peroxisome proliferator-activated receptors (PPARG, PPARD, and PPARA), fatty acid binding proteins (FABP4 and FABP3), free fatty acid receptor 1 (FFAR1), and cyclooxygenase-1 (PTGS1). These targets are primarily associated with lipid metabolism, glucose regulation, and inflammatory pathways. The results indicate that α-linolenic acid exhibits a multi-target mechanism of action, suggesting its potential as an antidiabetic, anti-inflammatory, and cardioprotective agent. This study provides valuable insights into the molecular basis of α-linolenic acid activity and highlights its potential for further development in pharmacological applications.

Formulation of Cream Extract Kratom Leaf (Mitragyna speciosa Korth.) as Analgesic in Mice (Mus musculus)
type: item
description: Pain is an unpleasant sensation caused by tissue damage. One alternative pain management is the use of topical analgesics in the form of creams. Kratom leaves (Mitragyna speciosa Korth.) are known to contain alkaloids that have analgesic potential. This study aims to formulate a cream preparation of kratom leaf extract and evaluate its physical characteristics and analgesic activity. The cream preparations were made in three variations of extract concentrations: 10%, 25%, and 50%. Physical quality evaluation showed that all formulas met the organoleptic requirements, homogeneity, pH, viscosity, spreadability, and adhesiveness with an oil-in-water emulsion type. The pH value of the preparation was in the range of 4.56–5.50, viscosity 4,266–24,766 cPs, spreadability 5.05–5.66 cm, and adhesiveness 4.64–22.91 seconds. Increasing the extract concentration caused a color change in the preparation from light brown to dark brown. Analgesic activity testing using the hot plate method showed that all formulas had analgesic activity indicated by an increase in the pain threshold after administration of the preparation. The percentage increase in the pain threshold in Formula I (10%) was 14.35%, Formula II (25%) was 17.17%, and Formula III (50%) was 20.68%, while the positive control (counterpain cream) was 33.07% and the negative control (cream base) was 0%. This study concluded that cream formulated with kratom leaf extract exhibited analgesic activity as evidenced by the increase in pain threshold in mice.

Comparative Study of Vitamin C Content in Rome Beauty Apples (Malus sylvestris Mill) with Several Processing Methods
type: item
description: Apples are known to contain antioxidants and vitamin C which play important roles in protecting the body from oxidative stress and degenerative diseases. However, vitamin C is sensitive to heat, light, and oxygen, which can lead to degradation during processing. This study aimed to compare the vitamin C content of Rome Beauty apple (Malus sylvestris Mill.) in various processed forms commonly consumed by the public, including fresh apple, apple juice, cider, dodol, and apple chips. The research was conducted using a titrimetric method with 2,6-dichlorophenol-indophenol dye to determine vitamin C content. Five samples were analyzed in duplicate. The data were statistically tested using the Kruskal–Wallis and Mann–Whitney tests to evaluate differences among samples. The vitamin C content ranged from 2.85 to 12.36 mg/100 g. The highest content was found in fresh apples (12.36 mg/100 g), followed by apple juice (6.41 mg/100 g), apple extract (5.23 mg/100 g), apple dodol (2.85 mg/100 g), and apple chips (2.85 mg/100 g). Statistical analysis showed significant differences (p < 0.05) among the samples, particularly between fresh or juiced apples and processed forms such as dodol and chips. Processing significantly reduces the vitamin C content of Rome Beauty apples. Heat treatment, oxidation, and exposure to air during processing are the major factors contributing to vitamin C loss. Therefore, consuming fresh apples provides the greatest nutritional benefit in terms of vitamin C intake.

Lifestyle Interventions for Blood Pressure Control: A Narrative Review of Global Evidence and Indonesian Perspectives
type: item
description: Hypertension remains a major global public health concern with a steadily rising prevalence, including in Indonesia. Global estimates indicate that over 30% of the adult population is affected, while in Indonesia the prevalence ranges between 34–36%. This narrative review synthesizes findings from 35 scientific articles published within the last decade, examining the relationship between lifestyle factors and blood pressure control. Literature searches were conducted through PubMed, ScienceDirect, Google Scholar, SpringerLink, and Garuda databases. The results demonstrate that high sodium intake, physical inactivity, obesity, psychosocial stress, smoking, and excessive alcohol consumption are major determinants of elevated blood pressure. Lifestyle modifications encompassing the DASH dietary pattern, sodium restriction, regular physical activity, weight management, and stress reduction have been shown to significantly lower both systolic and diastolic blood pressure. Comprehensive strategies integrating lifestyle modification, healthcare optimization, and sustained patient education are essential for effective hypertension control.

Comparison of Antioxidant Activity of Extracts and Fractions of Bay Leaves (Syzygium polyanthum (Wight.) Walp.) Using the DPPH (2,2-diphenyl-1-picrylhydrazyl) Method
type: item
description: Free radicals contribute to oxidative stress and chronic diseases, driving interest in natural antioxidants. This study evaluated the antioxidant activity of bay leaf (Syzygium polyanthum) ethanol extract and its dichloromethane and ethyl acetate fractions. Extraction used 70% ethanol maceration, followed by liquid-liquid fractionation. Antioxidant capacity was assessed via the DPPH radical scavenging assay at various concentrations (50–200 ppm), with results expressed as half-maximal inhibitory concentration (IC₅₀) values. Phytochemical screening was also performed. The ethanol extract exhibited the strongest activity (IC₅₀ = 47.89 ppm, classified as very strong), followed by the dichloromethane fraction (IC₅₀ = 73.88 ppm, strong), while the ethyl acetate fraction showed weak activity (IC₅₀ = 326.60 ppm). Phytochemical analysis revealed the presence of alkaloids, flavonoids, tannins, saponins, and steroids, with distribution varying across fractions. Statistical analysis of inhibition percentages showed no significant difference (p > 0.05), likely due to limited replicates, but the IC₅₀ trend clearly indicates superior radical scavenging by the polar constituents of the crude ethanol extract

description: Chia seed oil (Salvia hispanica) contains bioactive compounds, including tocopherols and phenolics, which exhibit antioxidant properties against free radicals. This study aimed to evaluate the antioxidant activity of chia seed oil, determine the optimal nanoemulsion formulation based on physical characteristics and antioxidant activity, and develop a nanoemulgel preparation. Antioxidant activity was assessed using the DPPH method. Nanoemulsion optimization was performed by varying concentrations of the surfactant Cremophor RH 40 and cosurfactant PEG 400. The best formulation (Formula 1) consisted of Cremophor RH 40 (80%), PEG 400 (10%), and chia seed oil (5%). The selected nanoemulsion was incorporated into a nanoemulgel containing 30% nanoemulsion and 70% gel base composed of Carbopol (0.5%), DMDM hydantoin (0.5%), and propylene glycol (5%). The nanoemulgel was evaluated for organoleptic properties, pH, viscosity, homogeneity, spreadability, adhesiveness, emulsion type, stability, and antioxidant activity. Results demonstrated that the formulation possessed good and stable physical characteristics, with strong antioxidant activity (IC₅₀ = 22.10 ppm). These findings indicate its potential for development as a natural-based pharmaceutical and cosmetic product.

Adsorptive Removal of Chemical Oxygen Demand Using Eggshells and Tea Waste Entrapped in Calcium Alginate
type: item
description: This study aims to assess the efficiency of two agricultural wastes as biosorbents to remove the chemical oxygen demand (COD) from a batik wastewater sample. COD-containing batik wastewater was treated with a combination of biosorbents by eggshells and tea waste activated using H?SO? and then immobilized in calcium alginate through the entrapment technique. The contact time, pH, and biosorbent dose were all investigated to examine the efficiency of biosorbent to remove COD. The independent variables for the optimization process are the contact time (47.13, 50, 60, 70, and 72.87 min), pH of the samples (1.71, 2,3, 4, and 4.28), and the ratio of the number of biosorbent between eggshells: tea waste (2.67:12.33, 3.75:11.25, 7.5:7.5, 11.25:3.75, and 12.33:2.67). The Characterization of the biosorbents was investigated using scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and energy-dispersive x-ray (EDX) analysis. The results show that eggshells and tea waste immobilized by calcium alginate with a ratio of 2.67 g: 12.33 g, a contact time of 60 min, and a sample pH of 3 are 89% effective in removing the COD in batik wastewater samples.

HPLC-HRESI-MSn Characterization of Polyphenolic Compounds in the Stem Bark of Chlorophora regia A. Chev (Moraceae)
type: item
description: Isolation and identification of secondary metabolites from medicinal plants could be tedious and time consuming. Therefore, any technique that could be used to confirm the identity of medicinal plant constituents without isolating them will save time and resources. Chlorophora similar to many genera in the Moraceae family have been demonstrated to be rich sources of polyphenolic compounds with important biological activities. The current study was designed to employ HRESI-MSn analyses to qualitatively examine isolated polyphenolic compounds from the stem bark of Chlorophora regia. Based on the HRESI-MSn data obtained, the fragmentation patterns of the compounds under study will be proposed and could be used in their identification in a matrix. Five polyphenolic compounds were successfully isolated and purified using various chromatographic techniques including column chromatography, thin-layer chromatography (TLC) and preparative HPLC. The structures of the isolated compounds were elucidated by in-depth analyses of their 1D and 2D NMR and mass spectroscopic data. HRESI-MS/MS was further used to characterize the isolated compounds. Five polyphenolic compounds including three Diels-Alder type adducts: sanggenon C, kuwanol E and chalcomoracin; two stilbene derivatives: chlorophorin and isochlorophorin were isolated from the stem bark. The tandem MS fragmentation patterns of the compounds in positive mode, were successfully proposed. The fragments obtained and proposed fragmentation patterns of the isolated compounds could be employed qualitatively in the identification of the studied polyphenolic compounds in a matrix.

type: item
description: SARS-COV-2 virus is a new coronavirus variant that causes the severe acute respiratory syndrome. COVID-19 can cause abnormalities in various organs. It is due to increased levels of cytokines causing a cytokine storm. Cytokine storms occur due to an increase in the innate immune system to eliminate infectious agents. Activation of the production of inflammatory mediators causes pulmonary fibrosis, interstitial fluid infiltration, and impermeability in blood vessels. Qutshul al Hindi, or in Latin called Sausurea sp contains anti-inflammatory activity. However, the study about the definite benefit of bioactive in this plant against COVID-19 and their mechanism, especially to the immune system, needs more explanation. Therefore, this review discusses their mechanism against COVID-19 by activating immune cells. In the literature research, we approach the studies that examine the secondary metabolite of Qutshul al Hindi that is effective in activating and enhancing the immune response against covid 19. Our literature review shows that qutshul al Hindi (Sausurea sp) has anti-inflammatory activity by inhibiting expression and activity of cytokine proinflammation induced by the innate immune system. So that this plant is a promising herb as a therapeutic candidate for covid-19 by regulating the immune system to produce and activate cytokine pro-inflammatory.

Green Preparation of Cu Nanoparticles with Bioreductor of Red Dragon Fruit Peel Extract: Visible Spectroscopy Properties
type: item
description: Copper nanoparticles have been successfully synthesized using the green synthesis method by utilizing red dragon fruit peel extract as a bioreductor. Red dragon fruit peel contains secondary metabolites that can reduce Cu2+ ions to Cu0. Physically, the formation of copper nanoparticles is indicated by a color change from light blue to green. In addition, the success of copper nanoparticles of red dragon fruit peel extract can be analyzed using a Visible and Fourier Transform Infrared (FTIR) spectrophotometer. The measurements using a Visible spectrophotometer showed the formation of copper nanoparticles at absorption peaks in the wavelength range of 400-450 nm. The stability of copper nanoparticles can be determined through the SPR peak absorption for 30 minutes, which shows that copper nanoparticles have good stability and have an estimated particle range of 46.43-92.93 nm, with a band gap value of 2.45 eV. The results of the FTIR spectrum on copper nanoparticles-red dragon fruit peel extract show a shift in the absorption peak of the wave number 3412.07 cm-1 to a wave number of 3439.07 cm-1 indicating a reduction of Cu2+to Cu0.

The Effect of Solvent Concentration Against Specific and Non Specific Parameters of Standardization: Ethanolic Extract of Papaya Seed (Carica papaya Linn.)
type: item
description: Papaya plants (Carica papaya L.) can be used as traditional medicine. The parts of the plant commonly used as medicine are the seeds and leaves. Assurance of the quality of the extract obtained needs to be carried out by testing specific and non-specific parameters. The aim of the study was to determine the effect of the percentage of ethanol solvent concentration on specific parameters (organoleptic, phytochemical screening, and total phenolic content) and non-specific parameters (moisture content, ash content, and specific gravity) of papaya seed extract (Carica papaya L.). This type of laboratory experimental qualitative research was done to determine the effect of the percentage of ethanol solvent concentration (70% and 95%) on specific and non-specific parameters. Specific and non-specific parameter testing is based on work procedures listed in the Indonesian Herbal Pharmacopoeia. The results of testing the specific parameters on organoleptics showed no difference in the extract obtained, which was viscous and dark brown in color with a characteristic odor. Based on qualitative phytochemical screening, 70% ethanol extract contains alkaloids, flavonoids, tannins, and saponins. However, the 95% ethanol extract was only positive for alkaloids, flavonoids, and tannins. The phenolic content test of 70% ethanol and 95% ethanol extracts was 4.31 ± 0.65 mg GAE/g and 2.69 ± 0.41 mg GAE/g, respectively (Sig 0.022 < 0.05). Extract non-specific parameter test results. The ash content test for 70% and 95% ethanol extracts was 9.5% ± 0.21% w/w and 8.5% ± 0.06% w/w (Sig 0.043 < 0.05). The respective water contents were 8.7 ± 0.11% w/w and 9.7 ± 0.26% w/w (Sig 0.046 < 0.05). The specific gravity of each obtained was 0.88 ± 0.006 % g/ml and 0.75 ± 0.006% g/ml (Sig 0.043 < 0.05). The conclusion of this study is that the concentrations of 70% ethanol and 95% ethanol in papaya seed ethanol extract have an effect on specific parameters, namely the measurement of total phenolic cont…

Isolation and Cytotoxic Activity Test of Alkaloids from Dichloromethane Fraction of Bark of Tampa Badak (Voacanga foetida (Blume) Rolfe) Against T47D Cell Line
type: item
description: Cancer is a problem in the health sector because this disease has an increasing incidence of morbidity and mortality. While the treatment still leaves some drug side effects, which cause discomfort for cancers sufferers. The arises because most cancer drugs work non-selectively. Because of some of the problems above, it is necessary to encourage the search for alternative drugs treatment of cancer. Voacanga foetida (Blume) Rolfe (Apocynaceae) is a species of plant from the genus Voacanga known as the tampa badak from West Sumatra. This plant is known to be source of indole alkaloids and also bis-indole alkaloids potential as cancer drugs. Therefore, in this study we are interested to explore the potency of this plant as natural product sources with potential cytotoxic activity. The study was started from the isolation process and continued by characterization of the isolated compounds and then testing their cytotoxic activity T47D breast cancer cell line. The isolation process of alkaloid compounds were performed by acid-base extraction, liquid-liquid fractionation, and followed by separation using column chromatography. Then,the potency of cytotoxic activity of the isolates were screened through Brine Shrimp Lethality Test (BSLT) method and evaluated by MTT assay. The structure of three isolated alkaloids (VFB-DB1.1; VFB-DB2.1; and VFB-DB2.2) were charachterized using spectroscopic analyses, including UV and FT-IR. One isolated compound (VFB-DB1.1) was also characterized using 1H NMR spectroscopy. Based on the similarity of 1H NMR spectra of isolated compound when compared with the literature, compound VFB-DB1.1 was identified as voacangine. Then, the BSLT and MTT assay result showed that VFB-DB1.1 exhibited LC50 value of 15.8 µg/mL againt Artemia salina L.and IC50 value of 8.9 µg/mL against T47D breast cancer cells, respectively.

Effect of Education on Knowledge and Attitude Level Related to Vitamin D in Pharmacy Students
type: item
description: Indonesia is a country located in the tropics with sun exposure throughout the season. Sun exposure is the best source of vitamin D and there have been no cases of vitamin D intoxication due to excessive sun exposure. Pharmacy students tend to lack knowledge of vitamin D. Changes in lifestyle and modernization lead to high use of sunscreens which can lead to a decrease in the synthesis of vitamin D in the skin. This research was conducted to determine the differences in knowledge and attitudes towards sun exposure using cross sectional method on 100 first semester pharmacy students and 100 final semester students. Test differences in aspects of knowledge and attitudes using odds ratios. The results of the knowledge aspect odds ratio test are 1,000 and the attitude aspect odds ratio test results were 0.583 so that it can be concluded that both knowledge and attitudes towards sun exposure have the same risk tendency for first semester and final semester pharmacy students.

Test of Antidiabetic Effect of Taro Leaf Extract (Colocasia esculenta L.) on Zebrafish (Danio rerio)
type: item
description: Diabetes mellitus (DM) is a common metabolic disorder defined as chronic hyperglycemia. In addition to the symptoms associated with hyperglycemia itself such as thirst, polyuria and weight loss, it can also cause acute hyperglycemia emergencies that are potentially life threatening. One of the traditional plants that has potential as an antidiabetic drug is the taro plant (Colocasia esculenta L) because it contains chemical compounds such as alkaloids, flavonoids, saponins, tannins and polyphenols which are known to have antidiabetic effects. This study aims to determine the effectiveness and what dose of Taro Leaf Extract gives the best effect of reducing blood glucose levels in zebrafish. This study used zebrafish (Danio rerio) induced with alloxan and glucose to raise blood glucose levels. The 20 test animals used were divided into 6 groups, namely group 1 without treatment (normal), group 2 control (-) alloxan induction 0.1% + glucose 1%, group 3 control (+) metformin, group 4 taro leaf extract 200 mg, group 5 taro leaf extract 300 mg, group 6 taro leaf extract 400 mg. Then glucose levels were measured using a glucometer. Data analysis was carried out statistical tests. The results showed that a dose of 400 mg/2L had the ability to reduce blood glucose levels that were not significantly different from normal zebrafish glucose levels.
