No full textThis research was carried out at the UPTD BIH Gedung Johor, Medan Johor, Medan City, starting from December 2023 to February 2024. This research aims to determine the effect of cucumber plant growth and production on the provision of potassium silica and cow manure. This research used a factorial randomized block design (RAK) with 2 treatment factors. The first factor is potassium silica with the symbol (K) which consists of 3 treatment levels, namely: Ko = Without potassium silica 0-gram polybag, Ki = 2.5 cc/ liter of water, K2 = 5 cc/ liter of water. The second factor is cow manure with the symbol (S) which consists of 4 treatment levels, namely: So = No fertilizer, S = 100 grams/polybag, S2 200 grams polybag, and S: = 300 grams/polybag. The parameters observed in this study were plant length (cm), number of leaves (strands), flowering age (days), number of fruit per plant (fruit), weight of fruit per plant (kg), number of fruit per plot (fruit), weight of fruit per plot (kg). The results of the research showed that Potassium Silica treatment had a significant effect on flowering age, and the number of fruit per plot, and had a very significant effect on fruit weight per plot. Providing cow manure fertilizer had no significant effect on all parameters. The best fruit weight per plot was obtained in the K0S2 combination, namely 2.13 kg.

No full textNutrient deficiency in soil has a negative impact on plant growth and productivity. Limited use of chemical fertilizers and poor soil conditions encourage the need for environmentally friendly alternatives. One solution is the utilization of organic waste such as goat manure, rice husks, and bran as raw materials for compost fertilizer. This training aimed to improve the knowledge and skills of SETMA members at the Faculty of Forestry, Tadulako University, in processing organic waste into quality solid fertilizer. The training was carried out in three stages: preparation, implementation, and evaluation. The implementation phase included theoretical sessions on nutrient content and material benefits, followed by hands-on practice in compost production, from mixing materials, fermentation using EM4, to storage. Evaluation was conducted through pre-tests, post-tests, and observation during practice. The results indicated increased understanding and active participation among participants. This training not only equipped them with technical skills but also raised awareness about the importance of managing organic waste to support sustainable agriculture. It is expected that this activity can be widely implemented and serve as a model for environmental education in both academic and community settings

No full textBackground: MDG (Millennium Development Goals) supports good umbilical cord care as one of the efforts to prevent neonatal infections, especially due to infection. Proper umbilical cord care, keeping it dry and clean, is the key to achieving the MDG target which leads to a decrease in infant mortality. Lack of maternal knowledge in caring for the umbilical cord causes mothers to use traditional medicine, allowing the development of clostridium tetani which can cause infection in neonates.
Objective: To determine the level of knowledge of postpartum mothers about umbilical cord care for newborns in the Alue Bilie Health Center Work Area, Darul Makmur District, Nagan Raya Regency in 2025.
Research method: this study uses an analytical method with a cross-sectional approach with a Proportional Systematic Random Sampling sampling technique with a sample size of 42 people, data collection using an umbilical cord care questionnaire. The time of this study was conducted on May 1 to May 20, 2025 with univariate and bivariate analysis with the chi square test.
Research results: most respondents had given birth more than once (multiparous) namely 25 people (59.5%). The level of respondent knowledge about umbilical cord care was in the Good category as many as 20 respondents (47.6%) where 26 people understood how to care for the umbilical cord.
Conclusion: the results of this study indicate that the knowledge of postpartum mothers in the Alue Bilie Health Center area regarding umbilical cord care is in the good category.
Recommendation: for the research location, it is hoped that health workers can minimize the incidence of neonatal infection due to improper umbilical cord care by providing education to postpartum mothers shortly before the mother goes hom
Gastritis in medical students: An analysis of contributing factors
No full textGastritis, defined as inflammation of the stomach lining, can arise from various factors, including Helicobacter pylori infection, stress, poor dietary habits, and the use of certain medications. Medical students represent a population particularly susceptible to gastritis due to high academic pressure, irregular eating patterns, and smoking habits. This study aimed to analyze the risk factors for gastritis among medical students at Prima Indonesia University. This study employed a cross-sectional design involving 123 medical students. Data were collected through questionnaires, and statistical analysis was performed using SPSS version 27. The majority of the study subjects were 21 years old (61.8%) and female (74.8%). Irregular eating habits (82.1%), coffee consumption (74%), and academic stress (79.7%) were prevalent among the subjects. More than half of the subjects had a history of gastritis (57.7%). The risk factors significantly associated with gastritis included female sex (OR=2.362; 95% CI: 1.030-5.414), irregular eating patterns (OR=3.707; 95% CI: 1.385-9.918), coffee consumption (OR=2.569; 95% CI: 1.126-5.861), and academic stress (OR=3.062; 95% CI: 1.227-7.638). Age did not significantly affect the risk of gastritis. Females were found to be more susceptible to gastritis than males, possibly due to hormonal influences and lifestyle factors. Irregular eating patterns and coffee consumption increased the risk of gastritis; however, smoking habits did not show a significant association. Academic stress was identified as an important risk factor, as it can increase gastric acid production. The risk factors significantly associated with gastritis among medical students were female sex, irregular eating patterns, coffee consumption, and academic stress
In vitro cholesterol-lowering activity of probiotics isolated from commercial products in Medan City
No full textRegular consumption of probiotic drinks has been shown to provide numerous benefits for human health. One of the primary benefits is boosting the immune system by promoting optimal digestive health. Ten brands of probiotic milk were collected, and bacterial isolates were obtained through a series of isolation and purification steps. The characterization of these isolates involved morphological and biochemical tests, including Gram staining, catalase activity assessment, and tolerance testing under simulated gastric conditions. The cholesterol-lowering activity of the isolates was evaluated in vitro by assessing their ability to reduce cholesterol levels in a simulated intestinal environment. The results demonstrated the presence of potential probiotic strains with cholesterol-lowering activity, providing a foundation for further research into the development of functional dairy products with cholesterol-lowering properties. The results indicated that probiotic milk from commercial beverages demonstrated a favorable response to bile salts in individuals with high cholesterol levels. Probiotic bacteria, such as Lactobacillus acidophilus, can survive in bile, facilitating the deconjugation of bile salts. This suggests that regular consumption of probiotic milk may aid in managing cholesterol levels in individuals with unhealthy lipid profiles. A significant relationship exists between the tolerance of probiotic milk to the digestive environment and its effectiveness in managing cholesterol. Mechanisms including bile salt deconjugation, short-chain fatty acid (SCFA) production, and increased cholesterol excretion contribute to cholesterol management. With appropriate formulation, probiotic milk can effectively control cholesterol levels, particularly in individuals at risk for cardiovascular disease
The impact of white turmeric rhizome extract on the histopathological characteristics of the pancreas in male wistar rats with diabetes
No full textThis study investigates the potential of white turmeric (Curcuma zedoaria Rosc.) rhizome extract as a cost-effective treatment for managing diabetes, focusing on its impact on pancreatic histopathology and blood glucose levels in diabetic Wistar rats. The research employed a randomized pre-test and post-test control group design, with rats induced with alloxan to simulate diabetes. The treatment groups received varying doses of white turmeric extract (250 mg/kg BW, 500 mg/kg BW, and 750 mg/kg BW) for 14 days. Histopathological analysis of the pancreas revealed that the white turmeric extract groups showed no signs of edema, inflammation, or necrosis, indicating a protective effect. Blood glucose level measurements demonstrated that the 500 mg/kg BW dose exhibited the most optimal results in lowering blood glucose levels. Statistical analysis using ANOVA and Kruskal-Wallis tests indicated significant differences between groups. These findings suggest that white turmeric extract, particularly at a dosage of 500 mg/kg BW, holds promise as a complementary treatment for managing diabetes by improving pancreatic health and reducing blood glucose levels. Further research is warranted to explore the underlying mechanisms and optimize its application
Risk factors for anemia among pregnant women at Bhayangkara Medan Hospital
No full textAnemia is a common complication affecting approximately 30% of pregnant women worldwide. Anemia is defined as a hemoglobin level of less than 11 grams per deciliter (g/dL) in non-pregnant women and less than 10.5 g/dL in pregnant women. This study aimed to determine the prevalence and risk factors of anemia in pregnant women. A cross-sectional study was conducted with 75 samples from 306 pregnant women who underwent ANC at the Bhayangkara Medan Hospital between January and June 2022. The risk factors studied included parity, pregnancy spacing, diet, maternal knowledge, and family support. Data regarding the risk factors were collected using questionnaires and medical records. Frequency distribution calculation and the chi-squared test were used for data analysis. The results showed that 30.7% of pregnant women experienced anemia. Chi-square test results showed that pregnancy spacing (0.001), diet (0.002), maternal knowledge (0.039), and family support were risk factors for anemia in pregnant women. Parity alone was not associated with anemia (0.306). The increased risk of anemia during pregnancy is influenced by short pregnancy spacing, poor diet, lack of maternal knowledge, and lack of family support

Model ini dilatih menggunakan data historis harian dari tahun 2010 hingga 2024, yang mencakup beragam variabel ekonomi makro dan mikro yang secara empiris diketahui memiliki pengaruh signifikan terhadap pergerakan harga emas, seperti indeks pasar saham utama, harga komoditas energi dan logam mulia lainnya, tingkat inflasi, suku bunga acuan, dan nilai tukar mata uang terhadap dolar AS. Melalui proses pra-pemrosesan data yang cermat, pemilihan fitur yang relevan, dan optimasi parameter model, diperoleh model prediksi yang mampu menangkap pola kompleks dalam data dan menghasilkan perkiraan harga emas dengan tingkat akurasi yang tinggi. Hasil evaluasi model menunjukkan bahwa Gradient Boosting Regression mampu mengungguli metode prediksi tradisional, dengan nilai Root Mean Squared Error (RMSE) sebesar 0,323 dan Mean Absolute Percentage Error (MAPE) sebesar 0,002 sehingga model ini dapat mencapai akurasi 99,96%. Analisis sensitivitas terhadap perubahan parameter model juga dilakukan untuk menguji robustitas model. Model prediksi yang dikembangkan dalam penelitian ini memiliki potensi besar untuk dimanfaatkan oleh investor, analis pasar, dan pembuat kebijakan sebagai alat bantu dalam pengambilan keputusan investasi yang lebih baik. Namun, perlu diingat bahwa model ini memiliki keterbatasan, seperti asumsi stasioneritas data dan potensi perubahan struktur pasar yang dapat mempengaruhi kinerja model di masa depan. Oleh karena itu, perlu dilakukan pembaruan model secara berkala untuk memastikan keakuratan prediksi. Penelitian ini juga menyarankan perlunya eksplorasi lebih lanjut mengenai pengaruh peristiwa global yang tidak terduga, seperti pandemi atau konflik geopolitik, terhadap pergerakan harga emas
