Extraction is a crucial stage in obtaining bioactive compounds from natural materials that have potential as medicinal, cosmetic, or nutraceutical ingredients. Among the various extraction methods available, maceration remains one of the most widely used techniques due to its simplicity, cost-effectiveness, and ability to maintain the stability of active compounds. The maceration process involves soaking powdered plant material in a suitable solvent at room temperature for a certain period, accompanied by periodic stirring to facilitate the diffusion of active compounds into the solvent. This method is particularly effective for extracting polar and semi-polar compounds such as flavonoids, phenolics, and essential oils that are sensitive to heat. The review shows that the effectiveness of maceration is influenced by several key factors, including the type and concentration of solvent, particle size of the material, duration of soaking, and stirring frequency. The use of ethanol with higher concentrations generally yields greater extract recovery and higher levels of active compounds. In addition, maceration is considered environmentally friendly because it requires no excessive heating and can employ safe, natural solvents. Therefore, despite the development of advanced extraction technologies, maceration remains a relevant, practical, and efficient method for phytochemical extraction, especially in laboratory research and small-scale herbal industries.

Acute Respiratory Infections (ARI) in the working area of Mulyorejo Public Health Center, where an aluminum factory is located, rank first among the ten most common diseases. This study aims to analyze the influence of sociodemographic characteristics and PM2.5 exposure on ARI complaints in the aluminum factory area of Payageli Village, Deli Serdang Regency. The cross-sectional observational study involved 160 housewives living within a radius of 10–1500 meters from the factory’s chimney. The analysis included univariate, bivariate, and multivariate methods. Results showed that 58.1% of respondents experienced ARI symptoms in the past month. The average ambient (outdoor) PM2.5 concentration measured from three sampling points was 12.3 µg/m³, which did not exceed the WHO standard (<15 µg/m³). The highest concentration was recorded in the southern direction (15.5 µg/m³). Bivariate analysis indicated that education (p = 0.010), direction of house location (p = 0.001), and indoor PM2.5 concentration (p = 0.006) were significantly associated with ARI. Multivariate logistic regression analysis showed that the most dominant factor influencing ARI was indoor PM2.5 concentration (p = 0.039), followed by education (p = 0.013) and direction of house location (p = 0.001). This study provides a scientific basis for air quality control and housing environment improvement to reduce the risk of environmentally related diseases in industrial zones.

Pediculus humanus capitis, according to the WHO, is classified as a skin disease and ectoparasite in the list of neglected tropical diseases. The cause can infect the scalp, leading to many children suffering from iron deficiency and anemia. Its spread occurs through shared items. Therefore, traditional insecticides such as srikaya seeds and kemiri seeds, which contain saponins and flavonoids capable of killing head lice, are required. The obective of this study is to determine the most effective concentration, compare their efficacy, and determine the killing time of both extracts. The experimental research method involved treatments at concentrations of 20%, 40%, and 60% with four repetitions. The results of this study indicate that there is an effect of srikaya seed extract with kemiri seeds in terms of concentration and time on lice mortality, as shown by a two-way ANOVA test with a p-value of 0.000 (P<0.05). In the Tukey test, the average mortality rate for srikaya seeds was 4, and the average mortality rate for kemiri seeds was 3. The concentration of srikaya seed extract killed 50% of head lice LC50 at a dose of 0,14%, while the concentration of kemiri seed extract killed 50% of head lice at a dose of 0,28% with contact times of 30 and 60 minutes. This demonstrates that srikaya seed extract at a dose of 0,14% is effective in causing mortality in head lice (Pediculus humanus capitis)

Infertility affects approximately 8–12% of couples worldwide, with male factors contributing to nearly half of all cases. Varicocelectomy, particularly the microsurgical subinguinal technique, is now considered the primary treatment that provides superior reproductive outcomes compared to conventional or laparoscopic approaches. To evaluate and compare fertility outcomes and recurrence risks between microsurgical and conventional inguinal varicocelectomy, based on recent evidence from 2020 to 2025. Methods A systematic review was conducted using databases including PubMed, Scopus, Cochrane, ScienceDirect, and Google Scholar. Out of 371 identified articles, 9 studies met the inclusion criteria. Results, most studies demonstrated that the microsurgical technique significantly improved sperm concentration, motility, and morphology, as well as higher natural pregnancy rates. The risks of hydrocele and recurrence were also markedly lower than those observed with laparoscopy. The average postoperative sperm count increased by 7.7 ± 4.5 million/mL (p< 0.001). Furthermore, the microsurgical subinguinal approach allows for more precise identification of arteries and lymphatic vessels, thereby minimizing vascular injury and facilitating faster recovery. Conclusion, the microsurgical subinguinal varicocelectomy has proven to be more effective and safer than conventional approaches. This technique significantly enhances semen parameters and pregnancy rates, while reducing the risk of hydrocele formation and recurrence.

Water plays a fundamental role in sustaining human life, particularly as a source of drinking water. Nonetheless, the consumption of water that does not comply with established health standards can result in illnesses such as diarrhea and vomiting. In the Patrang District, the use of refillable drinking water has gained popularity as an economical substitute for bottled water. Despite its convenience, there are growing concerns about the microbiological safety of refillable drinking water, especially regarding contamination by Coliform and Escherichia coli bacteria, which serve as key indicators of water hygiene and safety. The objective of this research was to determine the contamination levels of Coliform and Escherichia coli bacteria in refillable drinking water. The study utilized a quantitative research design with descriptive analysis and employed the Most Probable Number (MPN) method for testing. Data collection took place from May to June 2024, comprising five water samples labeled X, Y, Z, A, and B, obtained from refillable drinking water depots in Patrang District using a simple random sampling approach. The results indicated that out of the five samples tested, the sample labeled Z was positive for Coliform with an MPN value of 920 cfu/mL, while the sample labeled A was positive for both Coliform and Escherichia coli with an MPN value of 2,000 cfu/mL. From these findings, two samples (Z and A) were identified as contaminated, with the highest bacterial concentration found in sample A, which had an MPN value of 2,000 cfu/mL

The root of Mimosa pudica L. contains mimosine, a toxic alkaloid, as well as tannins that exhibit toxic properties, potentially disrupting pancreatic function. Exposure to sufficiently high concentrations of toxic compounds can impair cellular metabolism, leading to irreversible damage. One of the cellular changes induced by cytotoxic compounds is the reduction in the size of pancreatic Langerhans islets. This study aimed to investigate the effects of ethanol extract of Mimosa pudica roots on the diameter of Langerhans islets and β-cell damage in the pancreas of mice. Twelve mice were randomly divided into four groups, each consisting of three animals. Group I served as a control and did not receive the extract, whereas Groups II, III, and IV were administered root extract at doses of 10 mg/g BW, 100 mg/g BW, and 1000 mg/g BW, respectively, for 14 consecutive days. The results demonstrated that administration of ethanol extract of Mimosa pudica roots reduced the diameter of pancreatic Langerhans islets in a dose-dependent manner, with higher doses causing more severe β-cell damage. These findings highlight the need for caution in the use of Mimosa pudica roots as traditional medicine or dietary supplements.

Mimosine is an aromatic amino acid found in Mimosa pudica L. (sensitive plant) and is known to possess toxic properties that can damage various organs, including the kidneys. This study aimed to investigate the effect of ethanolic root extract of Mimosa pudica on renal damage in mice (Mus musculus). Twelve mice were divided into four groups: a control group and three treatment groups that received ethanolic root extract of M. pudica at doses of 10 mg/mouse/14 days, 100 mg/mouse/14 days, and 1000 mg/mouse/14 days. Following treatment, the mice were dissected to measure serum creatinine levels as an indicator of renal function, and histopathological observations of kidney tissues were performed using Hematoxylin-Eosin staining. The results revealed that administration of the ethanolic root extract of M. pudica significantly increased serum creatinine levels (P < 0.05), indicating impaired renal filtration function. Histologically, several types of tissue damage were observed, including glomerular atrophy, hydropic degeneration, and cellular necrosis, with hydropic degeneration being the most predominant and glomerular atrophy the least frequent. These findings suggest that mimosine, an active compound in M. pudica roots, exhibits a dose-dependent nephrotoxic effect, where increasing extract concentrations exacerbate renal tissue damage. Therefore, caution is advised in the medicinal use of M. pudica, as despite its pharmacological potential, high-dose or prolonged exposure may pose a serious risk of renal dysfunction.         

This study aims to determine the effect of digital media use on children's academic achievement.

Using a qualitative descriptive approach, this study provides an in-depth description of how digital media is used in learning activities and its impact on student learning outcomes. Data were collected through observations, interviews, and documentation of students, teachers, and parents involved in the technology-based learning process. The results indicate that digital media plays a significant role in increasing children's interest and motivation in learning, enriching their knowledge base, and helping them understand the material more effectively. However, the study also found that excessive, unsupervised use of digital media can lead to decreased concentration, the development of procrastination, and decreased social interaction among students. Therefore, the use of digital media needs to be balanced with guidance and supervision from teachers and parents to ensure its use remains aligned with educational goals. In conclusion, digital media has significant potential to improve children's academic achievement when used wisely, purposefully, and in accordance with each student's individual learning needs.

The addition of butterfly pea (Clitoria ternatea) extract which contains antioxidants into pasteurized milk is expected to increase the intake of antioxidants in the body. This research was conducted to evaluate the effect on pH, color, organoleptic chracteristic, and antioxidant activity of pasteurized milk. This study used a completely randomized design (CRD) with 5 treatments and 4 replications. The results of this study showed that increasing concentration of extract decreased pH, brightness, redness and yellowness. P3 was the most preferred treatment according to sensory evaluation. The antioxidant activity increased proportionally with extract concentration, reflected in decreasing IC50 values from 116.54 ppm (P0) to 19.06 ppm (P4). These findings indicate that the enrichment of pasteurized milk with butterfly pea extract effectively enhances its antioxidant capability while maintaining favorable sensory properties, particularly at moderate extract concentrations.

This study examined the effect of modified mung bean powder (Vigna radiata) media with the addition of glucose and chitin on the growth of Trichophyton rubrum. The results of the One Way ANOVA test showed a p value = 0.931 (p>0.05), indicating no significant difference between the modified media and Sabouraud Dextrose Agar (SDA). Media with a concentration of 2% showed a colony diameter of 97.8% of the control, proving the ability of mung bean nutrition, glucose, and chitin to support fungal growth. The color of the media varied from light to dark yellow without affecting the morphology of the colony. The best growth occurred on the 4th to 14th day with a cotton-like colony texture. These results confirm the potential of modified mung bean media as an economical, environmentally friendly, and effective alternative to SDA, especially for laboratories with limited resources, as well as opening opportunities for the development of local media based on other natural materials.

This study aimed to evaluate the effect of adding Eucheuma spinosum seaweed on the quality of goat milk dodol on moisture, protein, fat, and color (L*, a*, b*). Goat milk was chosen due to its high nutritional value and better digestibility than cow milk, although its consumption in Indonesia remains limited because of its strong odor, while dodol, a traditional Indonesian confection with a chewy texture, was used as a base product to promote milk utilization. The research material was dodol made from goat milk, glutinous rice flour, sugar, and salt, with the addition of Eucheuma spinosum seaweed at concentrations of 0% (T0), 10% (T1), 20% (T2), and 30% (T3). The method used was a laboratory experiment employing a Completely Randomized Design (CRD) with four treatments and five replications. The obtained data were then analyzed using analysis of variance (ANOVA). If significant differences were found, the Duncan Multiple Range Test (DMRT) was conducted. The results showed a protein content value of 5.33%-6.37%. Fat content value of 11.96%-13.19%. Ash content value ranged from 1.49%-3.96%. Texture value ranged from 16.22 N-26.44 N. pH value ranged from 6.76-6.94. Color parameter value L* ranged from 39.65-45.39; a* 5.16-8.33; b* 21.16-22.71.

The increasing transportation activity in urban areas contributes significantly to air pollution, particularly through emissions containing Nitrogen Dioxide (NO₂). This reactive oxidizing gas can cause respiratory disorders and eye irritation, especially among high-risk groups such as permanent vendors working in bus terminals. This study aimed to analyze the environmental health risks of NO₂ exposure and identify related health complaints among permanent vendors at Brawijaya Bus Terminal, Banyuwangi Regency. A descriptive observational study with a cross-sectional approach was conducted and analyzed using the Environmental Health Risk Assessment (EHRA) method. Secondary data on NO₂ concentrations were obtained from the Banyuwangi Environmental Agency (average 0.00874 mg/m³), while primary data on respondent characteristics and health complaints were collected through questionnaires involving 10 permanent vendors. The results showed that the Risk Quotient (RQ) values for both realtime and lifetime exposure were below 1, indicating no significant non-carcinogenic risk. However, 60% of respondents reported coughing, 30% experienced shortness of breath, and 40–60% reported eye irritation. These findings indicate potential long-term health effects even though NO₂ levels remain below national air quality standards. Regular air quality monitoring, vehicle emission control, and health education for vendors are recommended to reduce exposure risks in transportation environments.
