The clinical journal of science in the health analyst study program is a scientific journal that discusses the competence of health analysts which includes the competencies of Microbiology, Hematology, Parasitology, Immunoserology, Toxicology, and Clinical Chemistry. The clinical journal of science will be published every six months, in one period each academic year will be published twice, namely in June and December. This clinical journal of science was created primarily to assist lecturers, practitioners and students in publishing their scientific work. The background in making this clinical science journal is: 1. As a forum to accommodate the interests of lecturers in writing scientific papers, 2. Making the Dawn Health Analyst Study Program as a research center related to health laboratories, 3. As a source of information for the community about the importance disease detection in the laboratory as early as possible. Such is the background in making clinical clinical journals.<br><a href="" target="_blank" rel="noopener"><img src="" width="100%"></a></p> AKTIVITAS ANTIBAKTERI EKSTRAK DAUN KITOLOD (Isotoma longiflora) TERHADAP PERTUMBUHAN BAKTERI Streptococcus pyogenes 2024-01-08T12:15:16+07:00 Ari Nuswantoro [email protected] Kartini Kartini [email protected] <p class="Normal1" style="text-align: justify;"><span lang="EN-US" style="font-size: 10.0pt; font-family: 'Times New Roman',serif;">Kitolod is a plant that is easy to grow in the tropics, including Indonesia. Kitolod leaves contain flavonoids, alkaloids, tannins, saponins and terpenoids that have the potential to be used as antibacterial agents to inhibit the growth of pathogenic bacteria such as <em>Streptococcus pyogenes</em>. This study aims to determine the antibacterial activity of kitolod leaf extract on the growth of <em>Streptococcus pyogenes</em>. This research is quasi-experimental with purposive sampling technique. Kitolod leaves were extracted by maceration method using ethanol then dissolved in 15% DMSO to obtain concentrations of 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, and 90%. Each concentration was replicated three times, and the control used the antibiotic bacitracin. After carrying out the antimicrobial sensitivity test using the Kirby-Bauer diffusion method, the results obtained were inhibition zones of 17.66 mm (sensitive), 18.16 mm (sensitive), 18.50 mm (sensitive), 19 mm (sensitive), 19. 83 mm (sensitive), 21.16 mm (sensitive), 21.83 mm (sensitive), 22.33 mm (sensitive), and 23.83 mm (sensitive) respectively, while the bacitracin control was 17.5 mm (sensitive). Thus, kitolod leaf extract proved to have antibacterial activity against the growth of <em>Streptococcus pyogenes</em>.</span></p> 2023-12-05T00:00:00+07:00 ##submission.copyrightStatement## PENGARUH STABILITAS KADAR TRIGLISERIDA PADA SERUM SEGERA DIPERIKSA DAN DITUNDA 7 HARI PADA SUHU 2-8◦C 2024-01-08T13:25:37+07:00 Iis Afriayani94 [email protected] Asrori Asrori [email protected] <p>Examination of triglyceride levels using serum specimens is recommended to be examined immediately, but the examination can be delayed due to factors such as power outages and equipment damage. Deferred serum should be stored in a proper manner. Storage of specimens is one of the pre-analytic stages with a large risk of error. Research Objectives: knowing effect of triglyceride levels in serum which were immediately examined and delayed for 7 days at temperature of 2-8<sup>o</sup>C. Research method: This research is experimental design with pre-test and post-test design. The research population, namely students of level 1 and 2 of the Department of Medical Laboratory Technology, Poltekkes Kemenkes Palembang, amounted to 221 people. The sampling technique used random sampling. Triglyceride levels were checked using the Biosystem-350 tool. Data analysis using Wilcoxon test.

Four hours after cutting, without preservatives chicken meat begins to spoil. Star fruit plants have many benefits from leaves, fruits and even stems. The flavonoid content in star fruit works by damaging the cytoplasmic membrane so that bacteria will be damaged and die. The purpose of this study was to determine the squeeze of star fruit (Averrhoa bilimbi L) in inhibiting the growth of germ numbers in fresh cut chicken. This type of research is a pure experiment with pre and post test design with control. Researchers provide treatment or intervention on a variable. From this treatment, changes or influences on other variables are expected. The results of this study resulted in the average number of germs in 0, 2, 4, and 6-hour controls was 1.1 × 109 CFU / gr; 1.65 × 108 CFU/gr ; 1.69 × 108 CFU/gr ; 5.7 × 108 CFU/gr.

There are many factors that can affect CRP levels including age, gender, and smoking status. Increasing age allows the emergence of several groups of rheumatic diseases. One of the rheumatism groups that often accompanies the elderly is <em>Rheumatoid Arthritis (RA).</em> Elderly is an age that has a greater chance of experiencing autoimmunity. RA sufferers in the elderly around the world have reached 355 million people, meaning that 1 in 6 elderly people in the world suffer from rheumatism. The resulting human immune response depends on lymphocytes, where systemic inflammation significantly suppresses cellular immunity. Based on the Central Java Health Profile (2019) it shows that the number of elderly people in Cilacap Regency is 174,143 people. This study aims to analyze the number of lymphocytes as an indicator of the immune response in the elderly against levels of CRP, RF. The method used is descriptive qualitative method. From the results of a study of 30 samples in residents of RW 03, Donan Cilacap Village, the results of qualitative examination of CRP and RF levels showed normal results (100%), and the lymphocyte count results obtained for a number of 12 samples showed low results.</p> 2023-12-05T00:00:00+07:00 ##submission.copyrightStatement## DENTIFIKASI CEMARAN BAKTERI Escherichia coli PADA AIR MINUM DI KELURAHAN TLOGOSARI WETAN KOTA SEMARANG 2024-01-08T13:38:37+07:00 Roni Afriansya [email protected] Sulistia Istiqomah [email protected] Iin Desmiany Duri [email protected] <p>Pada tahun 2021 telah dilakukan pemeriksaan bakteri <em>Escherichia coli</em> pada air sumur gali di Kelurahan Tlogosari Wetan hasil menunjukkan bahwa air sumur gali positif mengandung bakteri <em>Escherichia coli.</em> Dengan keberadaan bakteri <em>Escherichia coli</em> pada air sumur gali yang digunakan sebagai sumber air minum, memungkinkan tercemarnya air minum tersebut dengan bakteri <em>Escherichia coli</em> sehingga tidak sesuai dengan Peraturan Menteri Kesehatan Nomor 492/MENKES/Per/IV/2010 yang menyatakan bahwa air minum tidak boleh mengandung bakteri <em>Escherichia coli</em> per 100 ml sampel.

Pada beberapa kasus perkembangan peradangan hati akut ataupun menahun dapat menjadi sirosis hati. Virus Hepatitis B dtransmisikan secara vertikal dan horizontal. Penularan dari ibu kepada janinya melalui plasenta pada masa perinatal merupakan penularan vertikal, sedangkan penularan melalui cairan tubuh penderita Hepatitis B antara lain air liur, darah, atau cairan tubuh dan kontak seksual merupakan jenis penularan secara horizontal.

The study had a cross-sectional design by conducting hematological examinations on suspected Covid-19 patients undergoing PCR swabs. The study used two specimens; first, naso/oropharyngeal swab for PCR examination; second, venous blood with EDTA anticoagulant for examination of hemoglobin, leukocytes, platelets, NLR and ALC using an automated hematology equipment. Univariate analysis was performed to determine the mean and standard deviation. Independent variable data were tested by Kolmogorov-Smirnov which were then analyzed bivariately by independent t test. The mean age of the research subjects was 48.94 years. Most of the subjects who underwent PCR swab examination were women (63%) with positive PCR swab results of 88%. The mean NLR parameter was higher in patients with positive PCR than in patients with negative PCR with p value =0.025 (p&lt;0.05).

Accurate diagnosis is crucial for malaria elimination. The malaria diagnostic method utilized is the microscopic examination, which is easy and affordable. This method involves preparing thick and thin blood smears using capillary blood. However, when an anticoagulant is used in the preparation of thick blood smears for malaria, such as blood with anticoagulant, it may cause the blood smear to peel off or not adhere to the glass slide during hemolysis. Calcium chloride (CaCl<sub>2</sub>) is one of the reagents used in the hematology laboratory for prothrombin time testing.
