Abstract

Abstract: This study aim to describe the thinking process of elementary school fifth grade students in solving mathematics problem based on Krulik and Rudnick rule. This research was a qualitative research using the case study method. Sampling was done by a combination of purposive sampling and snowball sampling technique. The subject of research that used in this study was twelve subjects, that was: four high-ability students, four moderate-ability students and four low-ability students. The data was validated by using a time triangulation test. The results show: (1) At the step of reading and thinking, students do not directly identify all of the facts in writing. After identifying the facts, students identify questions from the given problem. Furthermore, students do not portray the problems encountered but directly process the needed information to answer the question; (2) At the step of exploring and planning, students organize the information on the matter. Students consider enough information on the matter because there is a relation between the known and the asked. On the other hand, students do not make tables, diagrams, charts, tables or images from a given problem, but directly chose a strategy to answer the question; (3) At the step of selecting the strategy, students use the making list of all possible answers strategy. Students write down all the possibilities answers in the answer sheet. However, there are students who also use the guessing and testing strategy, guess how the value of variable and test whether the variable value is correct. In addition there are also students who use simulation or experimental strategies, students try to experiments; (4) At the step of finding the answer, the student use estimation in finding the answer. On the other hand, there is one student who uses algebra ability to find the answers. Students are also assuming the third day as a variable. After obtaining the value of the variable, student examine whether the numbers are correct. (5) At the step of reflecting and extending, students can review the results of the calculation by return on the answer sheet. Then students find that the answer is correct. Furthermore, students assume no alternative other solutions. Then the students do not make a generalizations of matter and discover the concept of matter.Keywords: process thinking, mathematics and problem solving.

Abstract

Pendidikan adalah suatu proses sistematis yang bertahap serta berkelanjutan dimana setiap saat terjadi perkembangan baru sebagai upaya peningkatan output pembelajaran. Penggunaan media pembelajaran yang tepat dapat menjadikan proses belajar menjadi menarik dan menyenangkan serta dapat mengurangi kesalahfahaman. Dengan tujuan ingin memberikan pengalaman belajar yang menarik tentang mata kuliah materi elektronika peneliti melakukan rancang bangun multimedia e-learning menggunakan HTML. Metode yang dilakukan adalah menggunakan metode Rapid Application Development (RAD). Metode ini dilaksanakan menggunakan 4 tahap yaitu, Studi pendahuluan, Pembangunan media sistem, penerapan rancang bangun, dan evaluasi penelitian. Hasil dari penelitian ini adalah rancang bangun multimedia interaktif elektronika dasar dengan menggunakan bahasa HTML yang mampu dijangkau pembelajar . Media pembelajaran ini dharapkan mampu digunakan untuk menarik perhatian dan konsentrasi belajar pembelajar sehingga mampu menambah pemahaman pembelajar terhadap materi.

Abstract

Indonesia has enormous potential to develop the tourism sector. The role of the tourism sector in Indonesia's economic development is increasingly important. The contribution has been made by the tourism sector through foreign exchange earnings, regional income, regional development, investment, and employment increment as well as business development across various areas in Indonesia. One of the government's targets in the tourism sector is to increase foreign tourist visits. Grouping or clustering the countries of origin of the tourists need to be done to help the government in determining strategies. This study uses the K-means clustering algorithm to classify the data on the country of origin of tourists and evaluate the clusters using silhouette score for determining the appropriate number of clusters. The result of the silhouette score shows that K = 2 has a value of 0.8, which is the best cluster that can be used to classify data on the country of origin of tourists. Based on the test results of the clusters, both of the clusters were then identified as cluster 1 for the category of low visitors with 206 members and cluster 2 for the category of high visitors with 6 members, namely Malaysia, Singapore, China, Other Asia, Timor Leste, and Australia. The results of the clustering process are expected to be input data for further performance, namely mapping the right marketing strategy for the countries visiting Indonesia so as to increase foreign tourist visits to Indonesia.
