PERAMALAN PERTUMBUHAN PENDUDUK KABUPATEN SITUBONDO DENGAN MODEL ARIMA, DERET ARITMATIK, DERET GEOMETRI DAN DERET EKSPONENSIAL “THE FORECASTING GROWTH OF THE POPULATION IN SITUBONDO BY USING ARIMA, ARITMATICS, GEOMETRICS AND EXPONENTIALâ€
Get PDFAbstract. ARIMA models as the population forecasting in Situbondo is a model of ARIMA(3, 3, 3) and mathematically, it is stated as; =2,445–1,6632–0,148+0,9732–1,0746+ 0,4676+– 1,0635. Forecasting the population in Situbondo is 667646 people in 2012 and in 2013 is 677852 people. Some other approaches in determining the population is the Arithmetic growth formula, the result of forecasting in 2012 is 657540 people and in 2013 is 661626 people, Based on Geometric growth formula, the result of forecasting in 2012 is 19696459 people and in 2013 is 35211214 people and Based on Exponential growth formula the result of forecasting in 2012 is 657611 people and in 2013 is 661799 people. If we compare the data of the forecasted result of ARIMA model with the Aritmatics growth formula and Exponential growth formula, show that the data of the population with the last ten actual data is relatively similiar.The closed last ten actual data forecasting of population is the aritmatics growth formula, whereas the data of the population result for next two year based on the Geometric growth formula got the forecasted result which is different from the forecasted result of ARIMA model, Aritmatics growth formula and Exponential growth formula.

Get PDFAbstract. The learning strategy is one of cause influenced the student’s learning completion. It means that to reach high teaching quality, all studies, especially math, should be organized with the right organizing strategy, then explained to the students with the right strategy. One of the learning strategy which make the students learning desire grow by activating all student’s potential in visual, auditory, or kinesthetic were think talk write learning strategy with authentic assessment. The type of this research was classroom action research. The research aimed to find out the student’s activity, student’s learning completeness, and student’s respond to think talk write learning strategy. While the objects were students of X-1 Grade SMAN (Junior High School) 1 Tanggul Jember Residence with 40 students amount. The results of applied research after think talk write learning strategy with authentic assessment the average student in the first cycle with 82 reaching 92,5% completeness, where there are 37 students who completed and 3 students did not complete. Then proceed to the second round, second round results on the average value of 84,75 students to reach 100% completeness. Based on the success criteria for this study that at least 75% of the entire class of students there is scored 75-100 or completeness reach 75% -100%. Therefore, it is associated with learning the completeness criteria, the results of this study meets these criteria. It can be concluded that the application of think talk write learning strategy with authentic assessment can improve student learning outcomes in math study in SMAN (Junior High School) 1 Tanggul Jember.

Get PDFAbstract. In mathematics learning, the scoring method used was still dominated by one scoring method which only measure the students’ factual knowledge. Thus, the scoring method should be integrated in the teaching learning process, not merely on the result of learning it self. This research was conducted to improve the grade VIII-I student’s learning achievement and their active participation through the implication of Team Games Tournament (TGT) method of cooperative learning type with authentic assessment on the surface area of the prism and pyramid at SMPN 1 Jember in the 2012/2013 academic year. The research design was Classroom Action Research (CAR), and the data collecting method used was observation, test, interview, and documentation. From the actions implemented in each cycle, it was proved that the students’ score improved from 74,68% in Cycle 1, to 80,76% in Cycle 2. Thus, the average percentage of the second cycle was 76,32% and it fulfilled the research criteria, it showed that the implication of TGT can improve the students’ learning achievment and their active participation.

THE EFFECTIVENESS OF ADAMSBASHFORTH-MOULTONORDER 12 METHOD IN ANALYZING THE RABIES VIRUS TRANSMISSION MODEL
Get PDFAbstract. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas metode Adams Bashforth-Moulton dalam menganalisis model penularan virus Rabies. Model matematika sistem penularan virus Rabies direpresentasikan dalam bentuk persamaan diferensial biasa (PDB) non linear orde satu sehingga sulit diselesaikan dengan metode analitik. Metode numerik Adams Bashforth-Moulton order dua belas digunakan dalam penelitian ini karena sudah terbukti merupakan metode yang lebih teliti dalam menyelesaikan permasalahan yang sulit diselesaikan secara analitik. Sebagai perbandingan, digunakan metode Adams Bashforth-Moulton order sembilan untuk menganalisis tingkat keakuratan dan keefektivannya. Hasil penelitian menunjukkan bahwa metode Adams Bashforth-Moulton order dua belas memiliki nilai error yang lebih kecil dibandingkan metode Adams Bashforth-Moulton order sembilan. Hal ini menunjukkan metode Adams Bashforth-Moulton order dua belas lebih efektif dalam menganalisis model dinamika penularan virus Rabies.
