Comparison of Rainfall Forecasting in Simple Moving Average (SMA) and Weighted Moving Average (WMA) Methods (Case Study at Village of Gampong Blang Bintang, Big Aceh District-Sumatera-Indonesia

The changing climate causes rainfall to vary from period to period. This change has an impact on society, especially in agriculture such as crop failure. This study aims to predict rainfall in 2018 and 2019 with the Simple Moving Average (SMA) method and the Weighted Moving Average (WMA) method. Based on 2004-2018 data, the dry season occurs in February-October and the rainy season in November-January. The level of validation of forecasters in 2018 according to each the SMA method and the WMA method were 43.43% and 40.69%, respectively. Both of these methods are low and reasonable or acceptable. Based on the SMA method, the division of the dry season in 2019 is estimated in February-October while the distribution of the rainy season in the same year is in December-January. Based on the WMA Method that the distribution of the dry season is estimated in February-April, June-September and the rainy season in October-January and May

Correlation of saliva characteristics and caries in beta-thalassemia major patients

A patient with beta-thalassemia major is known to have poor oral hygiene and a high risk of caries. Some studies showed that patients with beta-thalassemia have low salivary flow rate and acidic saliva. A reduction in salivary flow rate and pH would increase caries susceptibility. The aim of this study was to determine the correlation between salivary flow rate and pH with DMFT index in patients with beta-thalassemia major. This study was a cross-sectional design. A total of 38 patients with beta-thalassemia major aged more than 12 years old at Dr. Mohammad Hoesin Palembang Hospital were included in this study. Their unstimulated saliva was collected by spitting methods, and the teeth were examined with DMFT Index. The salivary flow rate was expressed as ml/min and the pH was measured using a saliva pH indicator paper. Data were analyzed using Pearson correlation test to determine the correlation between variables. The result showed that the mean age of the patients in this study was 16.6 years old, with a higher number of female patients than males. Patients with beta-thalassemia major had low salivary flow rate (0.72 ml/5 min), acidic saliva (6.34), and high DMFT index (8.34). This correlation was statistically significant (p<0.01). It can be concluded that there is a strong negative relation between DMFT index with salivary flow rate and salivary pH in patients with beta-thalassemia major

THE EFFECT OF GAMBIER EXTRACTS (Uncaria gambir [Roxb.]) AS ANTISEPTIC ON GINGIVAL WOUND IN RATS

Background: The main principle in treatment of wounds is infection control by using antiseptic. Gambier (Uncaria gambir [Roxb.]) containing catechins and tannins reported that has an antiseptic effect. This aim of this study was to determine the effect of gambier extract as antiseptic on gingival wound in rats.Methods: In vivo study, used pretest-posttest only control group design had been conducted in Animal house, Medical Faculty of Sriwijaya University and Province’s Health Laboratory in Palembang. There were 30 white Wistar rats divided into fve groups. Group 1 was given 10% povidone-iodine ointment (positive control), group 2 was given a placebo ointment (negative control), group 3, 4, and 5 were given an ointment with 10%, 15%, and 20% gambier extracts. Gingival labial wound of the mandible was induced with cylinder diamond bur, then swabbed before and after treatment. Gingival swab samples were cultured in agar medium and incubated for 24 hours. The number of bacterial colonies from all groups were counted by colony counter. The statistical analysis was used IBM SPSS statistics version 22,0.Result: The result showed that the number of bacterial colonies from all groups decreased signifcantly after treatment, except for negative control. The higher concentration of gambier extract led the better effect of antiseptic.Conclusion: It can be concluded that gambier extract has antiseptic effect of gingival wound in rats

Developing Website-based Interactive Learning Media Integrated with Kirchhoff's Law Experimental Tools

Understanding the correct concept is a fundamental goal of learning physics. One material that is still vulnerable to conceptual understanding is Kirchhoff's law. For that, we need media that can bridge the understanding of the concept of this material. Media development by integrating real experimental tools with digital technology is the right solution to answer this problem. Integrated interactive Google site with tool practice form senior high school tool simplification designed for upgrade understanding concept science high school students on the material Kirchhoff's law electricity dynamic. Development used R&amp;D with 4D stages (Define, Design, Development, Disseminate). Media implementation used limited tests with some students and implementation through one class in a high school in Bandung. Data analysis used the Rasch model. Based on the results of Rasch Model analysis, students tested have a medium category, and the given predictions in the Google Sites were high and low. Based on the analysis results of student responses to tools, students who used the tool directly agreed and strongly agreed that it and Google Sites could improve their conceptual comprehension skills.Understanding the correct concept is a fundamental goal of learning physics.

COMPARISON OF WEIGHTED MARKOV CHAIN AND FUZZY TIME SERIES-MARKOV CHAIN METHODS IN AIR TEMPERATURE PREDICTION IN BANDA ACEH CITY

Air temperature prediction is needed for various needs such as helping plan daily activities, agricultural planning, and disaster prevention. In this research, Weighted Markov Chain (WMC) method and Fuzzy Time Series-Markov Chain (FTS-MC) method are applied to predict the weekly air temperature in Banda Aceh city. The purpose of this study is to find out how the results of the application and comparison of the accuracy of the WMC method and the FTS-MC method on weekly air temperature prediction in Banda Aceh City. The prediction result of air temperature in Banda Aceh city using the WMC method for the next three weeks obtained an air temperature of 26,5℃. The prediction results of air temperature in Banda Aceh city using the FTS-MC method for the next three weeks obtained predicted values of 26,66℃ for the 105th week, 26,79℃ for the 106th week, and 26,83℃ for the 107th week. The MAPE accuracy level of the WMC method is 1,5% and the FTS-MC method is 1,7%. This shows that the MAPE of the WMC method is smaller than the FTS-MC method so it can be concluded that air temperature prediction using the WMC method is better than the FTS-MC method
