Abstract

Background: TNF- α is a cytokine that plays an active role in the pathogenesis of gastritis. The correlation of TNF-α levels in the gastric mucosa with the severity of gastritis has long been known. However, few studies have assessed TNF-α levels in serum of gastritis patients. This study aims to evaluate correlation between serum TNF-α level with the degree of gastritis based on histopathology.Method: A cross sectional study on eighty gastritis patients that fulfilled the inclusion criteria underwent serum TNF-α examination, endoscopy, and biopsy. Rapid urease test was used for diagnosis of H. pylori infection. The severity of gastritis based on lymphocyte infiltration, neutrophil infiltration, atrophy, and intestinal metaplasia according to Updated Sydney System. Univariate and bivariate analysis (Chi-square, fishers exact, spearman correlation, and independent T-test) were done using SPSS version 22.Results: There were 41.25% patients infected with Helicobacter pylori. Serum TNF-α levels in the infected group were significantly higher compared to negative H. pylori (p < 0.05). There was significant positive correlation between serum TNF-α levels and degree of gastritis based on lymphocyte infiltration (r = 0.333; p = 0.003).Conclusion: There was a significant positive correlation between serum TNF-α level with the severity of gastritis based on lymphocyte infiltration.

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan proses Fenton dalam menurunkan kadar chemical oxygen demand (COD) dan kadar total suspended solid (TSS) dari limbah cair pabrik kelapa sawit (PKS) dan menentukan kondisi optimum dari parameter yang digunakan dengan Response Surface Methodology menurut Box- Behnken design. Sampel diambil pada keluaran pertama kolam anaerobik ketiga dari instalasi pengolahan limbah cair kelapa sawit yang mengandung nilai COD berkisar antara 8.000 hingga 12.000 ppm. Pada penelitian ini, dilakukan pengujian pada berbagai pH, konsentrasi FeSO4.7H2O dan konsentrasi hidrogen peroksida. Hasil  penelitian menunjukkan bahwa kemampuan proses AOP dengan metode Fenton dapat menurunkan konsentrasi COD dan TSS masing-masing adalah 70,7704% dan 88,3897% pada konsentrasi FeSO4.7H2O 3703,52 ppm, konsentrasi H2O2 5586,43 ppm, dan pH 3.

Abstract:This research aimed to produce comic media with guided inquiry models based on scientific literacy on circulatory system in humans for grade VIII junior high school students. It had been done in SMPN 4 Pekanbaru and the Faculty of Teacher Training and Biology in University of Riau on April of October 2019. This typeofresearch was a Reseach and Development (R&D) study using the ADDIE model which consists of five stages namely analyze, design, development, implement, and evaluate. This research only reached the development stage by conducting validation by validators and limited trials in stages I and II. The data obtained were analyzed statistically descriptive. The evaluation of the developed comic media includes 6 aspects, namely aspects of comic content, aspects of linguistic / communication, aspects of presentation, aspects of overall appearance, aspects of guided inquiry, and aspects of scientific literacy. The results of the average validationwith a guided inquiry model based on science literacy gained a score of 3.47 in the very valid category. The average results of the limited trial phase I get a score of 96.42% with a very good category and a limited trial phase II get a score of 94.28% with a very good category. Based on these data it can be concluded that the development of comic media with a guided inquiry model based on scientific literacy in the material of the circulatory system in humans for grade VIII junior high school students gets very valid and very good categories so that it is appropriate to be used as a source of learning and can be implemented in the learning process at school.KeyWords: Comic Media, Guided Inquiry, Scientific Literacy, the Material of Circulatory System In Human

Abstract

The primary objective of this study is to investigate the pattern of intraday tradingwithin industrial sector which are listed in LQ45 and the domination oftelecommuniaction sector in trading activities at the Jakarta Stock Exchange. Anexamination on the behavior of intraday stock trading activities at the Jakarta StockExchange in the period between 2002 and 2003 is accomplished in this study. Tradingactivities used in this study were volatility of return, volatility of stock price, volume oftrading (based on transactions), spread, relative spread, depth, and relative depth(based on order). Approximately 8 millions trading activities were particized into timeinterval of 30 minutes. Regression analysis with dummy variable for independentvariable was applied. Results of the study showed that there were high means oftrading activities both at the beginning and the end of trading. This finding is inaccordance with a number of theories and results of several empirical studies whichindicate that trading behaviors in each capital market are varied.

Abstract

Head lice (Pediculus humanus capitis) is an insect that carries a disease that makes the loss of confidence. Efforts of control and pembutuasan head lice is the use of natural insecticides, one of the plants that have the potential as a natural insecticide is duku skin extract (Lansium domesticum Corr.). The purpose of this study was to determine mortality of head lice (Pediculus humanus capitis) and to know the compounds contained in duku skin extract. The research used laboratory experimental method with design research design post only control group. Based on the result of the research, the most effective rate of death of head louse (Pediculus humanus capitis) is 15% concentration with 4 head of head louse (80%), while at concentration 10% is 2 tail (40%) and at concentration 5% there is a dead head louse 0 (0%). The results of this study can be concluded that duku leaf extract (Lansium domesticum Corr.) Serves as a natural insecticide due to the presence of secondary metabolite compounds that are active in killing head lice (Pediculus humanus capitis).
