Abstract

Fungsi Puskesmas berorientasi kepada upaya kuratif dan rehabilitatif, saat ini bergeser kepada upaya preventif dan promotif tanpa mengabaikan orientasi sebelumnya. Untuk dapat melaksanakan fungsi pelayanan laboratorium di puskesmas dibutuhkan sumber daya manusia yang mencukupi baik jumlah maupun mutunya. Berdasarkan Permenkes Nomor 46 Tahun 2015 tentang Akreditasi Puskesmas dokumen yang harus terpenuhi sesuai kriteria persyaratan akreditasi yaitu terdapatnya SOP tentang Pemantapan Mutu Internal (PMI) dan Pemantapan Mutu Eksternal (PME).  Bahan kontrol komersial sangat baik digunakan untuk pelaksanaan PMI karena sangat stabil sampai masa expiry date nya, namun secara ekonomis relatif mahal sehingga  untuk penggunaan bahan kontrol komersial secara rutin di laboratorium terutama laboratorium puskesmas atau laboratorium institusi pendidikan kurang terjangkau dan cukup memberatkan. Bahan kontrol yang banyak digunakan di antaranya bahan kontrol darah lengkap komersial untuk  pemeriksaan hematologi.  Berdasarkan hal tersebut tujuan penelitian adalah untuk menganalisis pembuatan bahan kontrol buatan dari Packed Red Cell sebagai alternatif penggunaan bahan kontrol komersial. Bahan tambahan yang akan digunakan  dalam penelitian adalah kuersetin yang diperoleh dari hasil fraksinasi daun teh hijau. Berdasarkan penelitian sebelumnya telah diketahui kuersetin dapat berfungsi sebagai antioksidan dan anti agregasi platelet. Metode penelitian yang digunakan adalah eksperimen laboratorium. Hasil penelitian setelah diuji secara statistik dengan uji GLM dapat disimpulkan bahan kontrol yang ditambah dengan kuersetin, jumlah eritrosit stabil selama 20 hari, lekosit stabil 15 hari dan trombosit disimpan selama 5 hari sudah tidak stabil, sedangkan bahan kontrol komersil disimpan selama 15 hari sudah terjadi penurunan jumlah sel.

Abstract

In hypertensive patients, platelet hyperaggregation occurs. Platelet hyperaggregation will have a bad outcome in acute infarction stroke, in the form of death or neurologic deficits. One plant species that can play a role in preventing hyperaggregation complications is tomato fruit (Solanum lycopersicum) which is a horticultural plant cultivated in Indonesia. The compound content in Tomato Fruit (Solanum lycopersicum) includes solanine (0.007%), saponin, folic acid, malic acid, citric acid, bioflavonoids (including lycopene, α, and ß-carotene), protein, fat, vitamins, minerals, and histamine which function as antiaggregation. This research uses 2 methods, namely survey and sampling methods to determine the scope of empowerment and education in the form of counseling and mentoring. Apart from that, another method used is an educational method in the form of counseling and assistance to provide an understanding of the use of tomatoes to prevent the risk of blood vessel blockages. The results of the research were 20 cadres with a presentation increase of 51.67%, while the results from 20 residents had a presentation increase of 75.06%. Wilcoxon test results with p value (Sig) < 0.05. This shows that there is a significant difference in scores between the pre-test scores and the post-test scores of cadres and residents of RW. 16, Cipageran Village, North Cimahi District, Cimahi City.

Abstract

Industrialization plays important role in the economy of developing countries, including increasing community welfare. However, the presence of poorly industries waste disposal system has negative impact to the environment. Therefore, it is necessary to overcome this problem with low-cost technology, called adsorption. In this research, silylated-montmorillonite (sMMt) has been successfully prepared as supporting material for adsorption of methylene blue by chitosan. The sMMt was characterized by FTIR, XRD, and elemental mapping techniques. The chitosan/sMMt composites were prepared through dissolution-precipitation method and produced rod-like morphology as observed by SEM. The adsorption process was carried out in a batch method by studying the pH and the adsorption contact time. The adsorption kinetic mechanism of the chitosan/sMMt nanocomposite followed pseudo-second order rather than Lagergren model indicating chemisorption predominant. The addition of silylated-montmorillonite into chitosan enhanced the methylene blue dye removal performance, which evidenced by improving Qe values by 10% compared to chitosan.

Abstract

Background Dengue hemorrhagic fever (DHF) is a viral disease transmitted by Aedes aegypti mosquitoes, posing global public health challenge. The Riau Islands Province has the highest incidence of DHF in Indonesia. Objective This study aimed to investigate the relationship between hematocrit and platelet levels with the cycle threshold (Ct) values of polymerase chain reaction (PCR) results in DHF cases in Batam City, Riau Islands Province. Methods A descriptive correlation study was conducted using data from 102 patients infected with the dengue virus. Hematocrit and platelet counts were measured using a hematology analyzer, while Ct values for DENV1, DENV2, DENV3, and DENV4 were obtained through real-time qRT-PCR. Pearson's correlation test was employed to analyze the relationship between these variables. Results The study found no significant gender difference in DHF incidence (males: 50%, females: 50%). The highest prevalence was observed in the 6–11 years age group (44.1%), followed by the 12–18 years group (25.5%), the >18 years group (24.5%), and the 1–5 years group (11.8%). DENV3 was identified as the dominant serotype. No statistically significant correlation was found between Ct values and hematocrit (p = 0.607) or platelet counts (p = 0.323). Conclusion DHF cases in this study showed no gender disparity, with the most affected group being children aged 6–11 years, and DENV3 was the prevalent serotype. Ct values did not show a statistically significant correlation with hematocrit levels or platelet counts, suggesting that these hematological parameters may not predict viral load in DHF cases.

Abstract

Stroke is part of Cerebro Vascular Disease (CVD), which is any form of blood circulation disorder affecting the brain or due to pathological processes in the blood vessels. Acute infarction stroke is caused by blockage or occlusion of the small cerebral arteries caused by blood clots (thrombus) originating from excessive clotting of platelets which must be given antiplatelet agents. Indonesia has biodiversity, including a diversity of plants that can be used as traditional medicine. One of the medicinal plants that contains natural ingredients that have the potential to have biological activity as an antiplatelet is papaya leaves (Noviar, 2023). Flavonoid compounds, steroids and tannins in free form and tannin-protein complexes have anti-aggregation properties. This research uses 2 methods, namely survey and sampling methods to determine the scope of empowerment and education in the form of counseling and assistance. Apart from that, another method used is an educational method in the form of counseling and assistance to provide an understanding of the use of papaya leaves to prevent the risk of blood vessel blockages. The results of research from 18 cadres showed that based on the Wilcoxon test, a sig value of 0.000 <α (0.05) was obtained. Thus, it can be concluded that the pre-test scores and post-test scores have a significant difference in scores with an increase in scores for cadres of 22.66% or 40.02%. Meanwhile, the results of the Paired T Test obtained a sig value of 0.000 <α (0.05), thus it can be concluded that the platelet aggregation value before and after administration of papaya leaves had a significant difference with a decrease in value of 9.94% or 13.87%. This shows that papaya leaves are effective in reducing platelet aggregation to prevent the risk of blood vessel blockages

Abstract

Background & Objective: Mycobacterium tuberculosis, often referred to as M. tuberculosis, is an infectious pathogen that is responsible for causing tuberculosis (TB), a prevalent condition that is a leading cause of death globally. The spread of tuberculosis bacteria that are resistant to certain medicines, such as isoniazid, is currently on the rise. Therefore, molecular testing, such as quantitative polymerase chain reaction (qPCR), is needed to rapidly and reliably identify isoniazid-resistant tuberculosis germs. Method: The purpose of this study was to assess the analytical specificity of TaqMan Probe and SYBR Green qPCR techniques for the detection of isoniazid-resistant tuberculosis. This study was descriptive and quantitative. Analytical specificity was ascertained using MTB DNA with the S315G mutation spiked with E. coli DNA. A paired t-test was used to assess the primary data. Result: The results show that the analytical specificity values based on the significance of the paired t-test for the SYBR Green and TaqMan Probe methods were 0.398 and 0.790, respectively. Conclusion: Based on these results, it can be concluded that the analytical specificity of the TaqMan Probe qPCR method was 1.99 times greater than that of the SYBR Green method.
