DETERMINATION OF SIMULTANEOUS SULFAMETHOXAZOLE AND TRIMETHOPRIM BY ULTRAVIOLET SPECTROPHOTOMETRY WITH MEAN CENTERING OF RATIO SPECTRA

 Objective: Mean centering of ratio spectra (MCR) is analysis method for determination levels of mixture that has maximum wavelength is overlapping, and without preliminary separation. The purpose of this study is a determination of sulfamethoxazole (SLF) and trimethoprim (TRM) mixture by ultraviolet spectrophotometry with MCR.Methods: Absorption spectra of each drug were recorded and divided by the corresponding concentration of divisor, and the ratio spectra were then mean centered. SLF and t TRM concentrations were determined from calibration graphs by measuring at obtained maximum wavelengths 256 nm for SLF and 288 nm for TRM.Result: The result determination of SLF and TRM content in tablet S was 103.31±0.34% and 96.588±2.13%, respectively, result of validation method was fulfilled, percentage recovery for SLF was 101.24% and relative standard deviation (RSD) was 0.41%, and percentage recovery for TRM was 100.89% and RSD was 0.96%.Conclusion: The determination simultaneous by ultraviolet spectrophotometry of MCR was found to be accurate, precise, simple, and rapid method and can be used for SLF and TRM mixture

The Aplication of Problem Based Learning Model on Heat and Temperature

This study aims to determine the effect of Problem Based Learning model to student learning outcomes on subject of Heat and Temperature. This research is quasi-experimental. Techniques that used to gain a sample is random-cluster-sampling technique that was chosen two classes as experimental and control classes. Instruments in the form of essays tests and observation sheets to measure affectivepsychomotor of students. Pretest data on both classes showed that both classes have the same ability. Then be given treatment which experimental class with Problem Based Learning and control class with Conventional Learning. From the t-test results there is effect of Problem Based Learning model to student learning outcomes

Evaluasi Kebijakan Beasiswa Bidik Misi di Universitas Riau Tahun 2010-2014

Bidik Misi scholarship is a programm to all students in College especially to all least coast fee about study and appreciate to the best student at Campus. Indonesia has 148 campus to the receive the Bidik Misi scholarship. University of Riau is a one of a campus get the Bidik Misi 2010 until 2014 scholarship and program has continue to the least poor in this area. Many problems who the writer found the some unjustice about the Bidik Misi scholarship in University of Riau. The writer has information from rektorat building in University of Riau. After that, the writer check this data, and begin to analizy with theory. The writer of this research using William Dunn theory about Evaluation of Policy. This is a theory to all problems, so the writer get a solution in this research after the writer finish interview about Bidik Misi scholarship.Keywords : Bidik Misi scholarship, Evaluation of Policy, University of Ria

Effect of Inquiry Learning Model and Motivation on Physics Outcomes Learning Students

The purposes of the research are: (a) to determine differences in learning outcomes of students with Inquiry Training models and conventional models, (b) to determine differences in physics learning outcomes of students who have high motivation and low motivation, (c) to determine the interaction between learning models with the level of motivation in improving student Physics learning outcomes. The results were found: (a) there are differences in physical students learning outcomes are taught by Inquiry Training models and conventional models. (b) learning outcomes of students who are taught by Inquiry Learning Model Training better than student learning outcomes are taught with conventional model. (c) there is a difference in student\u27s learning outcomes that have high motivation and low motivation. (d) Student learning outcomes that have a high motivation better than student learning outcomes than have a low motivation. (e) there is interaction between learning and motivation to student learning outcomes. Learning outcomes of students who are taught by the model is influenced also by the motivation, while learning outcomes of students who are taught with conventional models are not affected by motivation

Convolutional Neural Network and Feature Transformation for Distant Speech Recognition

In many applications, speech recognition must operate in conditions where there are some distances between speakers and the microphones. This is called distant speech recognition (DSR). In this condition, speech recognition must deal with reverberation. Nowadays, deep learning technologies are becoming the the main technologies for speech recognition. Deep Neural Network (DNN) in hybrid with Hidden Markov Model (HMM) is the commonly used architecture. However, this system is still not robust against reverberation. Previous studies use Convolutional Neural Networks (CNN), which is a variation of neural network, to improve the robustness of speech recognition against noise. CNN has the properties of pooling which is used to find local correlation between neighboring dimensions in the features. With this property, CNN could be used as feature learning emphasizing the information on neighboring frames. In this study we use CNN to deal with reverberation. We also propose to use feature transformation techniques: linear discriminat analysis (LDA) and maximum likelihood linear transformation (MLLT), on mel frequency cepstral coefficient (MFCC) before feeding them to CNN. We argue that transforming features could produce more discriminative features for CNN, and hence improve the robustness of speech recognition against reverberation. Our evaluations on Meeting Recorder Digits (MRD) subset of Aurora-5 database confirm that the use of LDA and MLLT transformations improve the robustness of speech recognition. It is better by 20% relative error reduction on compared to a standard DNN based speech recognition using the same number of hidden layers

Pengaruh Harga Minyak Mentah Dunia, Inflasi, Suku Bunga (Central Bank Rate), Dan Nilai Tukar (Kurs) Terhadap Indeks Harga Saham Sektor Pertambangan Di ASEAN (Studi Pada Indonesia, Singapura, Dan Thailand Periode Juli 2013 – Desember 2015)

This research is to explain the influence of crude oil price, inflation, interest rate (central bank rate), and exchange rate towards mining stock indices in ASEAN period of July 2013 to December 2015. All data was analyse with multiple linier regression technique regards on classical assumption to obtain BLUE (Best Linier Unbiased Estimation). The results show that crude oil price, inflation, interest rate (central bank rate), and exchange rate does have simultaneously relation towards mining stock indices in Indonesia and Singapore. Crude oil price and exchange rate does have partially relation towards mining stock indices both in Indonesia and Singapore, meanwhile in Thailand only exchange rate which have partially relation towards mining stock indices in Thailand
