Abstract

AbstractMathematics learning in SMP Negeri 3 Ngabang is still not optimal. The problem experienced is the lack of student involvement in the learning process. this is also related to the selection of inappropriate learning models. This affects the low student achievement. The purpose of this study was to determine the effectiveness of Creative Problem Solving (CPS) learning model on student mathematics learning achievement. The research method used is a quantitative method with comparative studies. The prerequisite test carried out normality test and homogeneity test. Hypothesis testing using the t-test. The results of the study show that the model CPS learning is effective against mathematics learning achievement compared to direct learning models. The results of the final data analysis showed the proportion of experimental class students had reached individual KKM with the results of tcount> ttable or 5.64> 1.68 Based on the average difference test obtained tcount= 1.751> 1.67 = t table and = 5%. Keywords: learning, learning achievement.

Abstract

AbstractThis research aims to find out the improvement of students' understanding of concepts in the basic mathematics subject of relations and functions. This type of research is an experiment, with one group pretest-posttest design research design. The study population was all first-level students of the Primary School Teacher Education Program (PGSD). The determined sample is class I.A as many as 26 students with a purposive sampling technique. Research instruments in the form of UTS questions and tests of students' conceptual understanding. Testing this hypothesis using the t-test. Before conducting a hypothesis test, first test the normality and homogeneity. The student group is divided into three categories, namely high, low, and medium based on UTS results. Furthermore, based on the normalized gain score test obtained an increase in the ability of mathematical understanding for groups of students who have high and medium ability with sufficient criteria. While the group of students who have low ability has an increase with low criteria. Overall the implementation of learning media using Macromedia flash can improve students' mathematical understanding abilities by 0.403, including enough categoriesKeywords: Macromedia Flash, Relationships and Functions, Mathematical Understanding

Abstract

AbstractThis study aims to empirically examine the effect of short-term and long-term Inflation, Amount of Current Money, Exchange Rate, Interest Rate of Bank Indonesia, World Oil Price (WTI) and Net Exports on the Composite Stock Price Index (IHSG) using the Error Correction Model method ( ECM) which is processed with reviews 6.0. During the observation period of 2000-2012, there was a relationship between macro variables and the movement of the JCI on the Indonesia Stock Exchange (IDX). The ECM test results show that inflation, exchange rates, and world oil prices have a significant effect on the JCI in the short term while the long-term variables that significantly affect the JCI are CPI, exchange rates, net exports, and world oil prices.Keywords: CSPI, CPI, JUB, Exchange Rate, Bank Indonesia Interest Rate (rSBI), World Oil Price (WTI), Net Export and Error Correction Model (ECM)

Abstract

Media pembelajaran merupakan alat bantu yang berfungsi  untuk menjelaskan sebagian dari keseluruhan program pembelajaran yang sulit dijelaskan seecara verbal ( Musfiqon, dalam Okto Ardiansyah, 2012). Matematika seringkali dianggap suatu hal yang menakutkan dikalangan siswa di sekolah karena identik dengan banyaknya konsep, khususnya pada materi integral dimana materi tersebut baru diperkenalkan pada siswa SMA sehingga siswa banyak yang mengalami kesulitan bahkan seringkali dirasakan sangat absrak sehingga dirasa kurang ada manfaatnya di kehidupan sehari-hari. Artikel ini merupakan hasil penelitian pengembangan produk dalam bentuk video tutorial pada materi integral untuk siswa SMA. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian pengembangan. Penelitian ini memenfaatkan video tutorial sebagai media pembeajaran. Instrumen yang digunakan dalam penelitian ini adalah lembar penelitan ahli materi dan media terhadapmedia pembelajaran. Setelah media pembelejaran dibuat selanjutnya divalidasi oleh  tim ahli. Validasi dilakukan oleh satu ahli materi dan  ahi desain. Setelah media divalidasi dan direvisi kembali menemukan kelemahan maka selanjutnya akan diuji coba penggunaanya. Dari hasil analisis validasi terhadap video tutorial pada materi integral diperoleh 81,25. Ini artinya mediapembelajaran yang telah dibuat sesuai dengan tujuan penggunaan mediapembelajaran. Sehingga media pembelajaran ini bisa digunakan oleh guru Matematika SMA  khususnya pada pembelajaran materi integral. Kata Kunci: video tutorial, kemampuan konseptual

Abstract

Hidden Markov model is a development of the Markov chain where the state cannot be observed directly (hidden), but can only be observed, a set of other observations and combination of fuzzy logic and Markov chain to predict Rupiah exchange rate against the Dollar. The exchange rate of purchasing and exchange rate of saling is divided into four states, namely down large, down small, small rise, and large rise are symbolized respectively S1, S2, S3, and S4. Probability of sequences of observation for 3 days later is computed by forwarding and Backward Algorithm, determine the hidden state sequence using the viterbi algorithm and estimate the HMM parameters using the Baum Welch algorithm. The MAPE result exchange rate of purchase of FTS-Markov Chain is 1,355% and the exchange rate of sale of FTS-Markov Chain is 1,317%. The sequences of observation which optimized within exchange rate of  purchase is X* = {S3,S3,S3}, within exchange rate of sale is also X* = {S3,S3,S3}. Keywords: Exchange rate, FTS-Markov Chain, Hidden Markov Model
