Evaluation of Acid Mine Drainage Neutralization Using CaO and Alum
type: item
description: Acid mine drainage (AMD) is a major environmental issue associated with coal mining activities, characterized by low pH and elevated concentrations of dissolved metals that can degrade water quality and harm aquatic ecosystems. Active treatment using alkaline materials such as quicklime (CaO) combined with coagulants like alum is widely applied to neutralize acidity and reduce metal content. This study aims to evaluate the effectiveness of CaO and alum in improving the pH of acid mine drainage. The research was conducted through a combination of field testing and laboratory analysis. The treatment process involved dosing quicklime and alum into acid mine drainage, followed by periodic pH measurements at inlet and outlet points over a one-month observation period. Data were analyzed using linear regression to determine the relationship between CaO dosage and pH changes. The results showed that the initial pH of acid mine drainage remained acidic, with an average value of 4.43, and increased slightly within the range of 4.43 to 4.76 after treatment. Regression analysis indicated a strong correlation (R² = 0.9537) between CaO dosage and pH increase, suggesting that higher dosages contribute to improved neutralization performance. However, the achieved pH values have not yet met the environmental quality standard (pH ≥ 6), indicating that further optimization of treatment dosage and process conditions is required. These findings highlight that while the combination of CaO and alum has potential in neutralizing acid mine drainage, its current application is not yet sufficient to achieve regulatory compliance and improvements in treatment design are necessary.

POTENTIAL OF MORINGA LEAF EXTRACT GEL (Moringa oleifera Lam.) AS AN ANTIBACTERIAL AGAINST Staphylococcus aureus CAUSES OF ACNE
type: item
description: Moringa leaves (Moringa oleifera Lam.) can be utilized by the community to heal wounds, beriberi, and fever; have anti-inflammatory and analgesic properties; and treat skin disorders caused by bacteria. One of the skin diseases is acne, which is caused by the bacterium Staphylococcus aureus. The aim of this study is to determine the antibacterial activity of a gel made from moringa leaf extract against Staphylococcus aureus and to identify the secondary metabolite compounds of the extract through phytochemical screening. This research is a laboratory experiment that involves creating moringa leaf extract gel at concentrations of 2%, 4%, 6%, and 8% to inhibit the growth of Staphylococcus aureus. Antibacterial testing was conducted using the well diffusion and disc diffusion methods and analyzed using one-way ANOVA. Based on the results of the phytochemical screening, the extract contains flavonoid, alkaloid, saponin, tannin, and terpenoid compounds. The results of the study showed that the antibacterial activity of the gel with the well method at concentrations of 2%, 4%, 6% and 8% obtained an average inhibition zone of 7.68 mm; 8.8 mm; 9.18 mm; 9.55 mm. While with the well method, the average inhibition zone at concentrations of 2%, 4%, 6% and 8% was 8.55 mm; 9.03 mm; 9.17 mm; 9.88 mm. The ANOVA test analysis obtained a result of p = 0.000 smaller than α = 0.05 which means there is a significant difference in the average diameter of the inhibition zone between the treatment groups.

DISSOLUTION TEST OF SESEWANUWA LEAF FRACTION TABLETS WITH VARIOUS BINDERS USING UV-VIS SPECTROPHOTOMETRY
type: item
description: The sesewanua plant has potent anti-inflammatory activity, particularly in the n-Hexane: Ethyl Acetate fraction, which contains alkaloid compounds. However, consuming the fraction can cause discomfort, making it important to develop it into a tablet for more practical use. Binders are used in tablet formulations because they bind the tablet components and affect tablet quality. This study aimed to determine the effect of the type of binder (PVP, starch, and Na-CMC) on the dissolution test results of N-Hexane: Ethyl Acetate Fraction tablets using UV-Vis spectrophotometry. The dissolution test was conducted to evaluate how quickly the active ingredient dissolves from the tablet. Four formulas were tested: F0 (without binder), F1 (5% PVP), F2 (5% starch), and F3 (5% Na-CMC). The formula with the best results was F2, containing 5% starch as the binder, with a dissolution percentage of 80.91%. This is because starch is the best binding agent because it can increase the percentage of active ingredient dissolution in tablets. Therefore, it can be said that the addition of starch provides the best results with a dissolution percentage that meets the requirements.

ADSORPTION STUDY OF LEAD (Pb²⁺) IONS USING CASSAVA PEEL BIOCHAR: EFFECT OF pH AND CONTACT TIME
type: item
description: This study evaluates the adsorption performance of NaOH-activated cassava peel biochar (Manihot esculenta Crantz) for the removal of Pb²⁺ ions from aqueous solutions, with particular focus on the effects of solution pH and contact time. Cassava peel biochar was produced via pyrolysis at 180–350 °C and chemically activated using 0.1 M NaOH. Surface functional groups and morphology were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy–Energy Dispersive X-ray (SEM–EDX). Batch adsorption experiments were conducted by varying solution pH (3–8) and contact time (30–120 min), while Pb²⁺ concentrations before and after adsorption were analyzed using Atomic Absorption Spectroscopy (AAS). The results showed that solution pH significantly affected Pb²⁺ adsorption, with the highest adsorption capacity of 9.94 mg/g achieved at pH 5. Contact time also influenced adsorption performance, and the optimum condition was obtained at 90 min, yielding a maximum adsorption capacity of 9.94 mg/g. These findings indicate that NaOH-activated cassava peel biochar exhibits stable and effective Pb²⁺ adsorption under slightly acidic conditions and moderate contact time, highlighting its potential as a low-cost and environmentally friendly adsorbent for Pb²⁺ removal from contaminated wastewater.

ASPARTATE TRANSAMINASE IN CHRONIC HEPATITIS B PATIENTS AT AWALBROS BATAM HOSPITAL
type: item
description: Chronic hepatitis B (HBV) is a liver infection characterized by persistent replication of Hepatitis B virus (HBV). Viral load is a parameter often used to evaluate viral replication activity, while Alanine Transaminase (ALT) and Aspartate Transaminase (AST) often used as biomarkers to assess liver damage. Objective: This study aims to evaluate the correlation of HBV viral load to ALT and AST in patients with chronic hepatitis B at Awalbros Batam Hospital. Methods: This research used descriptive study by data collected from patients with chronic hepatitis B who had undergone testing assessments of HBV viral load, ALT and AST. Results: The results of this study is indicate a significant correlation of HBV viral load to ALT levels. Approximately 40% of patients showed elevated ALT levels in line with increasing HBV load, while AST increase was observed in only about 5% of patients. The stronger correlation was noted in ALT, likely due to its higher specificity to liver tissue compared to AST. Conclusion: Quantitative HBV load significantly influences ALT levels but has a less notable effect on AST levels. These findings support the role of ALT as a more reliable indicator of chronic HBV infection. The study also simplifies the clinical phases of infection into two main categories: active and inactive, based on presumed similarities in clinical patterns.

Α-GLUCOSIDASE ENZYME INHIBITOR ACTIVITY OF ETLINGERA ELATIOR LEAF EXTRACT WITH SOLVENT VARIATION
type: item
description: Diabetes mellitus (DM) is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin production or utilization. The increasing prevalence of diabetes, especially type 2, is a global concern due to the risk of complications it poses. One approach in treating type 2 diabetes is to inhibit the α-glucosidase enzyme to slow down glucose absorption. This research aims to identify the potential of patikala leaf extract as an α-glucosidase enzyme inhibitor. Using an experimental method with patikala leaf samples collected from Mariri Hamlet, Banyuurip Village, Bone-bone District, North Luwu Regency. Extraction was performed using the maceration method with variations in solvents: 70% ethanol, ethyl acetate, and n-hexane. The α-glucosidase enzyme inhibition activity was measured using a microplate reader and analyzed to determine the IC50 value. From the percentage inhibition data, the IC50 values obtained for 30% ethanol extract of patikala leaves were 351.95 µg/mL, for 70% ethanol extract of patikala leaves were 444.83 µg/mL, for 96% ethanol extract of patikala leaves were 362.27 µg/mL, for ethyl acetate extract of patikala leaves were 163.59 µg/mL, and for n-hexane extract of patikala leaves were 294.90 µg/mL, indicating that patikala leaf extracts with variations in solvent or extraction method exhibited very weak α-glucosidase enzyme inhibition activity. In conclusion, based on the research results obtained, the extract with variations in the solvent or extractant. Patikala leaf extract has an inhibitory activity against the α-glucosidase enzyme, which is categorized as very weak because it has an IC50 value > 100 µg/mL. In comparison, the control (acarbose) is in the weak category with an IC50 value of 50-100 µg/mL.

type: item
description: Exposure to free radicals and oxidative stress are major factors in various degenerative diseases, such as cardiovascular disease, diabetes, cancer, and neurodegenerative diseases. Therefore, the use of natural antioxidant sources is important to reduce the negative effects of free radicals. This study compares the natural antioxidant potential of black rice, bajakah root, and kebiul seeds, whereas previous studies have only identified the antioxidant potential of a single natural ingredient. This study aims to measure the antioxidant potential, such as total polyphenols, total flavonoids, and antioxidant activity, of these three natural materials using distilled water, 70% ethanol, and 96% ethanol as solvents. The experimental research method involved testing antioxidant activity and measuring total phenolics and flavonoids. The results showed that the 70% ethanol extract of black rice had the highest total polyphenol content at 6.83±0.28 mgGAE/g (0.007±0.00%), the 70% ethanol extract of bajakah wood root had the highest flavonoid content at 8.77±0.02 mgQE/g (0.009±0.00%), and the distilled water extract of kebiul seeds showed the strongest antioxidant activity based on an IC50 value of 5.96 ± 0.01 ppm. This study concluded that black rice has potential as a primary source of phenolics and anthocyanins, while bajakah wood root and kebiul seeds are sources of flavonoids with strong antioxidant activity.

HPLC-DAD PROFILING OF SIDR LEAVES AND ROASTED CANDLENUT FOR ALOPECIA THERAPY
type: item
description: Alopecia is a dermatological disorder characterised by progressive hair loss, often impairing patients’ quality of life. Conventional therapies, such as minoxidil and finasteride, have demonstrated efficacy; however, their adverse effects have prompted the search for natural-based alternatives. Sidr leaves (Ziziphus spina-christi L.) and roasted candlenut seeds (Aleurites moluccanus L.) have been traditionally employed in ethnopharmacology for hair treatment, yet scientific data on their phytochemical composition remain limited. This study aimed to identify and quantify the major bioactive constituents in purified aqueous extracts of sidr leaves and roasted candlenut seeds using high-performance liquid chromatography coupled with diode-array detection (HPLC-DAD), and to assess their potential implications in alopecia therapy. Powdered sidr leaves and roasted candlenut seeds were extracted, fractionated, and analysed on a C18 column using a gradient acetonitrile–water mobile phase. The results revealed that sidr leaves are rich in rutin hydrate (245.64 ± 0.73 mg/L), accompanied by gallic acid (47.63 ± 0.43 mg/L) and quercetin (6.85 mg/L), whereas roasted candlenut seeds predominantly contain quercetin (27.00 mg/L). Rutin functions as an antioxidant and angiogenesis stimulator, gallic acid exhibits anti-inflammatory activity, and quercetin acts as a 5α-reductase inhibitor relevant to androgenetic alopecia. In conclusion, the phytochemical profiles of sidr leaves and roasted candlenut seeds support their potential use as phytotherapeutic candidates for alopecia management.

EVALUATION OF ANTIBIOTIC USE FOR DIARRHEA THERAPY IN TODDLERS AT PUSKESMAS BEJI DEPOK CITY
type: item
description: Acute diarrhea is diarrhea more than fourteen days and is generally caused by microbial infection. The principles management of acute diarrhea are rehydration, symptomatic therapy, and selective and rational antibiotic therapy. Previous study shown antibiotic prescriptions for diarrhea therapy are still quite high, a study at the Bangsal Puskesmas in Mojokerto Regency showed that 27% was inappropriate for the indication. The aim this study was to evaluate the rationality of using antibiotics for diarrhea in toddlers. This study is a descriptive study with retrospective data collection from the medical records of toddler diarrhea patients at the Puskesmas Beji in Depok City in 2021 who met the inclusion and exclusion criteria. The results of the study showed the use of antibiotics such as metronidazole, amoxicillin, and cotrimoxazole was the right choice because it was in accordance with the choice of antibiotic therapy for acute diarrhea with specific indications, however the results of the evaluation of antibiotic prescriptions were not appropriate indications there was still a high number 62,5% of antibiotic prescriptions for patients with non-specific acute diarrhea. Antibiotic prescriptions must be based on the bacteria causing the infection so it is very necessary to be supported by data from laboratory tests.

THE REMAINING CHEMICAL COMPOUNDS OF THE BODY'S METABOLISM ARE REDUCED THROUGH THE HEMODIALYSIS METHOD
type: item
description: The accumulation of metabolic residual chemical compounds, such as urea, and creatinine, is a major consequence of decreased glomerular filtration function in patients with chronic kidney disease (CKD). Increased concentrations of these compounds trigger internal homeostasis disorders and accelerate the progression of metabolic complications. Hemodialysis is a kidney replacement therapy that aims to eliminate toxic compounds and maintain the body's biochemical balance. The purpose of this study is to evaluate the effectiveness of hemodialysis in reducing urea, creatinine, and uric acid levels in CKD patients. The pre-post test research involved 30 stage V CKD patients who underwent routine hemodialysis at the Regional General Hospital (RSUD) Padang Panjang, West Sumatra. Venous blood samples were taken 15 minutes before and after a single hemodialysis session. Urea levels were analyzed using the urease-GLDH method, creatinine using the kinetic Jaffé method, and uric acid using the uricase-POD method. The data were analyzed using a paired t-test with a significance level of p<0.05.The results were obtained The average urea level decreased from 182.6 ± 28.7 mg/dL it was concluded that Hemodialysis significantly reduced the level of chemical compounds left over from the body's metabolism in patients to 76.3 ± 16.9 mg/dL (p<0.001), creatinine from 11.8 ± 2.9 mg/dL to 4.9 ± 1.3 mg/dL (p<0.001), and uric acid from 8.5 ± 1.8 mg/dL to 5.2 ± 1.1 mg/dL (p<0.001). It can be concluded that hemodialysis significantly reduces the level of chemical compounds left over from the body's metabolism in advanced CKD patients. Hemodialysis maintains biochemical homeostasis and reduces the risk of systemic complications.

type: item
description: Aging is an unavoidable physiological process. The process of premature aging is prevented using natural anti-aging cosmetics derived from plants. Cosmetics can be used as anti-aging products. Therefore, plants can be used as substitutes for anti-aging chemicals with fewer side effects. There are many herbal plants that are empirically used by the Baduy community and have potential as anti-aging agents with tyrosinase inhibitory and antioxidant activities. Evidence of anti-aging activity can be obtained by testing the effects of each herbal plant, which has been conducted by several researchers previously. The purpose of this article is to provide information on which plants have the potential as anti-aging agents for cosmetic raw materials thru a literature review of journals in electronic databases. The results obtained from several plants such as Carica papaya L., Kaempferia galanga, Psidium guajava, Zingiber officinale var. Rubrum, Piper bettle, Caesalpinia sappan L, and Etlingera elatior (Jack) R.M. Sm have tyrosinase inhibitory activity. Orthosiphon stamineus B., Coleus scutellarioides (L.) Benth, and Imperata cylindrica (L) Beauv., the cogongrass plant, use an antioxidant approach as anti-aging. In conclusion, all herbal plants from the Baduy tribe have the potential as raw materials for anti-aging cosmetics

description: Konyal passion fruit (Passiflora ligularis f. lobata) has been widely used as fruit juice by the community, it is necessary to conduct research to explore the potential of konyal passion fruit as a natural medicine. This study aims to determine the total phenolic compound content and antioxidant activity of ethanol extract from konyal passion fruit seeds using UV-Vis Spectrophotometry method. The sample was macerated with 70% and 96% ethanol solvent, repeated three times and the filtrate was concentrated using a rotary evaporator at 40°C. The extract obtained was determined by the concentration of phenolic compounds using the Follin - Ciocalteau method and the antioxidant activity test using the DPPH method with gallic acid as a comparison compound. The determination of the total phenolic compound content was obtained at 77,73 µg/mL at a wavelength of 747 nm. The antioxidant activity test of gallic acid obtained IC50: 2,04 µg/mL, and the antioxidant activity test of the sample obtained IC50: 21,89 µg/mL at a wavelength of 515 nm. Based on the IC50 value, it can be concluded that the antioxidant activity of the ethanolic extract of passion fruit seeds is in the very strong category, namely in the range <50 µg/mL. The equivalence of antioxidant activity of ethanolic extract of konyal passion fruit seeds with gallic acid is 1:10,73 mg, meaning that 1 mg gram of gallic acid is equivalent to 10,73 mg of ethanolic extract of konyal passion fruit seeds.

REMOVAL OF HEAVY METALS USING CHLORELLA VULGARIS: A REVIEW
type: item
description: In this review, the researchers describe a natural process that can remove heavy metals from the environment. The use of Chlorella vulgaris has more potential than other bioremediation processes. Chlorella vulgaris has been recognized as a biomaterial capable of removal and could be a potential alternative method for the physicochemical absorption of heavy metals. The removal of heavy metals using Chlorella vulgaris on living cells can occur rapidly, independent of absorption of metabolism to the cell surface and intracellular absorption. Non-living cells have also successfully removed heavy metals from liquid waste. As one of the innovative removal technologies, it depends on algae's biosorption and bioaccumulation capabilities, which dominate the bioremediation process. This study shows that the composition of Chlorella vulgaris constituents, such as proteins, lipids, carbohydrates, pigments, vitamins, and minerals, which have various amino acid, hydroxyl, carboxyl, and sulfate functional groups, are the main factors in the absorption process of heavy metals in liquid waste, so they have the potential sustainability in its use as a bio adsorbent in the removal of heavy metals in liquid waste in the future.

FORMULATION AND ANTIBACTERIAL ACTIVITY TEST OF ANTI-ACNE GEL FROM ETHANOL EXTRACT OF SENDUDUK LEAVES (Melastoma malabathricum. L)
type: item
description: Treatment of inflamed acne is done by administering antibiotics and chemicals, which can usually cause side effects such as skin irritation and resistance. To avoid this, it can be replaced by doing traditional treatment using natural ingredients. Senduduk plant (Melastoma malabathricum L.) is one of the natural ingredients that can be used to treat acne because it contains secondary metabolites of flavonoids, phenolics, tannins and terpenoids that are very potential as antibacterials. This study aims to determine the ethanol extract of senduduk leaves can be formulated in a physically stable gel dosage form and determine the antibacterial activity against Propionibacterium acne and Staphylococcus aureus bacteria. This study used an experimental method by making 3 types of formulas containing ethanol extract of senduduk leaves (Melastoma malabathricum L.) 1.5%, 2.5% and 3.5%. Furthermore, the evaluation of the gel preparation included organoleptic test, homogeneity test, pH test, spreadability test and adhesion test. Antibacterial activity testing was carried out by the pitting diffusion method using Klindamycin as a positive control. Based on the results of the gel preparation evaluation, it shows that the anti-acne gel preparation has physical quality that meets the standards. Antibacterial activity test of senduduk leaf ethanol extract gel against S.aureus bacteria at concentrations of 1.5%, 2.5% and 3.5% had inhibition zone diameters of 20.3 mm, 21.4 mm, and 24.2 mm, respectively, while against P. acnes bacteria it was 21.6 mm, 25.3 mm, and 26.5 mm. It can be concluded that the anti-acne gel of senduduk leaf ethanol extract has antibacterial activity against S. aureus and P. acnes bacteria and can be made into an anti-acne gel dosage form.
