Abstract

Background: Carbohydrates in kluwih seeds have sufficient nutrients, such as potatoes and tubers, making it possible to be used as a medium for mushroom growth. The nutritional composition of breadfruit contains 25% carbohydrates, 1.5% protein, and 0.3% fat. Aspergillus niger fungi require nutrients such as carbohydrates and protein to grow. This study aims to determine whether kluwih seed starch can be used as an alternative medium for the growth of Aspergillus niger fungi. Method: This study used a pre-experimental design with laboratory observation. The study was conducted by utilizing kluwih seed starch as a medium, compared to Potato Dextrose Agar (PDA) and Sabouraud Dextrose Agar (SDA). Results: The results showed that kluwih seed starch can be used as an alternative medium for the growth of Aspergillus niger, with fungal colonies that grow macroscopically and microscopically almost the same as PDA and SDA media. Conclusion: Kluwih seed starch can be an alternative substitute for PDA media for the growth of Aspergillus niger.

Abstract

Background: This study counts the number of leukocytes using a manual method. The natural materials used are lime, lemon, and tamarind, which contain glacial acid and citric acid with a pH below 2.0. These acids can lyse blood cells, except for leukocytes (white blood cells). Objective: This study aims to analyze the effectiveness of varying concentrations of starfruit (Averrhoa bilimbi) on the number of leukocytes (white blood cells). Method: This research employs an experimental method. The number of leukocytes is counted from the juice of starfruit at concentrations of 5% and 10%. The objective is to find the most effective concentration compared to the standard Turk solution as a control. Conclusion: The data were analyzed using One-Way ANOVA. The average number of leukocytes in the control group was 6,500, in the 10% concentration was 6,450, and in the 5% concentration was 4,500. The results of statistical tests and hypotheses showed a significance value of 0.000, which is less than ? (alpha) (0.05), thus the null hypothesis is rejected and there is a significant difference. The 10% concentration proved to be the most effective in replacing glacial acetic acid in the Turk solution.

Abstract

Background: Mycobacterium tuberculosis is known as a highly pathogenic bacterium. These bacteria are aerobic in shape like rods and have resistance to acids. This bacteria can cause tuberculosis (TB). TB disease has been widely recognized as a cause of death which is quite high in the world. Tuberculosis causes the death of nearly one million women each year. Currently, no country in the world is free from tuberculosis. Data shows that Indonesia is the third largest contributor of tuberculosis cases in the world. Examination of mycobacterium tuberculosis bacteria which is routinely carried out in hospitals or health centers uses microscopic diagnosis of acid-resistant bacilli (BTA). Recently, a rapid test of Mycobacterium tuberculosis was carried out using the semi-quantitative Real Time Polymerase Chain Reaction Assay (RT-PCR) method which targets the rpoB gene in Mycobacterium tuberculosis, which can automatically process preparations by extracting doxyribo nucleic acid (DNA) in a cartridge. The time needed for this diagnosis is approximately two hours until the results come out. Purpose: To see the results of the rapid test compared to the microscopic diagnosis at the Puskesmas. Method: Using the cross-sectional method, with a sample of 25 patients at the Lubuk Pakam Health Center. To detect Mycobacterium tuberculosis using the GeneXpert MTB/RIF tool. Furthermore, the data obtained was processed and examined using the Wilcoxon statistical test. Results: The value of the statistical test results using the Wilcoxon test showed that the p-value (Sig) was 0.264, the value was > 0.05, which means that in this study there were no significant differences in results between the microscopic method and RT-PCR. Conclusion: Overall there was no significant difference in the results between microscopy and RT-PCR methods. Keywords: Tuberculosis; Mycobacterium Tuberculosis; RT-PCR Pendahuluan: Mycobacterium tuberculosis dikenal sebagai bakteri yang sangat patogen. Bakteri ini berbentuk aerobik seperti batang dan memiliki ketahanan terhadap asam. Bakteri ini dapat menyebabkan tuberkulosis (TB). Penyakit TBC telah dikenal luas sebagai penyebab kematian yang cukup tinggi di dunia. Tuberkulosis menyebabkan kematian hampir satu juta wanita setiap tahun. Saat ini tidak ada satu negara pun di dunia yang bebas dari tuberkulosis. Data menunjukkan bahwa Indonesia merupakan penyumbang kasus tuberkulosis terbesar ketiga di dunia. Pemeriksaan bakteri mycobacterium tuberculosis yang rutin dilakukan di rumah sakit atau puskesmas menggunakan diagnosis mikroskopis acid-resistant basil (BTA).

Abstract

Clean and Healthy Living Behavior (PHBS) is a promotive and preventive effort that aims to improve the degree of public health through behavior change. Nursery reservoir employees have a high risk of exposure to the work environment in the form of dirty water, biological waste, and pathogenic microorganisms. This community service activity was carried out to increase the knowledge and practice of PHBS among employees of the nursery reservoir in Juata Tarakan based on national PHBS indicators. The implementation method includes counseling, demonstration, and evaluation using pre-test and post-test. The results showed a significant increase in employee knowledge, with an average pre-test score of 58.7 increasing to 78.3 in the post-test. The statistical test resulted in a value of p = 0.000 (p < 0.05), which confirms the effectiveness of PHBS educational interventions in improving workers' health knowledge and behavior. These findings provide practical implications that counseling-based education and demonstrations can be an effective strategy in encouraging the implementation of PHBS in risky work environments. Thus, this activity is expected to be able to support the creation of a healthier work environment, increase productivity, and become a model for community-based occupational health interventions.

Abstract

Dengue Hemorrhagic Fever (DHF) remains a serious public health problem in Tarakan City, Indonesia, with case numbers fluctuating annually. This study aimed to analyze trends in DHF incidence and map the spatial distribution of cases and the Larval-Free Index (LFI) in Tarakan City from 2016 to 2025. A descriptive observational study with a retrospective approach was conducted using secondary data obtained from the Tarakan City Health Department. The variables analyzed included the number of DHF cases, incidence rate (IR), case fatality rate (CFR), endemicity status of subdistricts, and the 2025 LFI. Descriptive analysis and Geographic Information System (GIS)-based spatial mapping were performed. The results showed fluctuating trends in DHF incidence throughout the study period. In 2025, 90 cases were reported, with an IR of 35.2 per 100,000 population and a CFR of 1.11%. Most cases occurred in endemic areas. Spatial analysis revealed an uneven distribution of cases, with some urban villages showing lower LFI values but higher dengue incidence. These findings indicate that GIS-based mapping can support the identification of priority areas for surveillance, vector control, and sustainable larval source reduction programs.

Abstract

Examination of helminth eggs in fecal samples remains the primary method for diagnosing helminth infections. A 2% eosin stain is commonly applied to improve contrast in microscopic preparations; however, synthetic dyes have limitations due to their chemical properties and low environmental friendliness. The senduduk plant (Melastoma malabathricum L.) contains natural pigments such as anthocyanins and flavonoids, which may serve as potential natural staining agents. This study aimed to evaluate the effectiveness of senduduk leaf and flower extracts as alternative stains to replace 2% eosin in identifying Trichuris trichiura eggs. This research used a laboratory experimental design consisting of one control group and five treatment groups. The treatments included flower extract with a flower-to-distilled water ratio of (1:5), pure flower extract (100%), flower extract with 70% alcohol (1:5), leaf extract with distilled water (5:1), and leaf extract with 70% alcohol (5:1). The results showed that all extract preparations were able to stain the microscopic slides, enabling clear observation of T. trichiura egg morphology. Extracts using alcohol as a solvent produced stronger and clearer contrast compared to those prepared with distilled water. In conclusion, senduduk leaf and flower extracts demonstrate potential as environmentally friendly natural alternative stains for parasitological microscopic examinations.
