PENERAPAN PENDEKATAN REALISTIC MATHEMATICS EDUCATION (RME) UNTUK MENINGKATKAN KEMAMPUAN OPERASI HITUNG SISWA SEKOLAH DASAR

Penelitian ini bertujuan untuk mengetahui pelaksanaan pembelajaran matematika tentang operasi hitung penjumlahan dan pengurangan bilangan bulat dengan menerapkan pendekatan Realistic Mathematics Education (RME) serta peningkatan kemampuan operasi hitung siswa setelah menerapkan pendekatan RME dalam pembelajaran. Penelitian ini dilatarbelakangi dari hasil observasi di lapangan selama peneliti mengajar sebagai praktikan di salah satu SDN di kota Bandung, tepatnya siswa kelas IV yang dijadikan subjek penelitian dikarenakan peneliti menemukan bahwa masih banyak siswa yang tidak bisa menyelesaikan operasi bilangan bulat hal ini dilihat dari beberapa soal yang diajukan peneliti untuk mengukur kemampuan operasi hitung dan hasil perolehan skor banyak siswa yang tidak mencapai KKM. Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) dengan menerapkan Pendekatan RME. Instrumen yang digunakan dalam penelitian ini adalah Tes, observasi guru dan siswa, serta catatan lapangan. Hasil penelitian menunjukan bahwa perencanaan yang disusun peneliti dengan menggunakan langkah-langkah pendekatan RME dan proses pembelajaran pun mengalami peningkatan pada aktivitas guru maupun siswa dari 93,75% pada siklus I menjadi 100% pada siklus II serta pembelajaran dengan menerapkan pendekatan RME membuat siswa lebih aktif dan menyukai pembelajaran hal ini membuat adanya peningkatan kemampuan operasi hitung siswa, hal ini dilihat dari hasil belajar yang mengalami peningkatan yakni pada siklus I rata-rata nilai siswa adalah 73,64 meningkat menjadi 87,05 pada siklus II dan ketuntasan belajar siswa pun mengalami peningkatan dari 68,18% pada siklus I menjadi 86,36% pada siklus II, bisa dilihat juga dari rata-rata gain yang diperoleh sebesar 0,4. Kesimpulan dari penelitian ini yaitu pendekatan RME dapat meningkatkan kemampuan operasi hitung penjumlahan dan pengurangan bilangan bulat siswa di salah satu SDN di kota Bandung. The study aims to describe the implementation of learning Mathematic which apply Realistic Mathematic Education (RME) approach and to improve students’ ability in calculating operation of addition and subtraction integers through the implementation of Realistic Mathematics Education (RME). The basis of the study reviews to the observation result in one of elementary schools in Bandung city at fourth grade. There are many students who cannot solve some questions in calculating operation, so most students got score less that KKM score. The method applied Classroom Action Research (CAR) which implement RME approach. The instruments used in collecting data are test, teacher and students observation, and field note. Furthermore, the result of the study shows that there is an improvement in the learning and teaching process from the average number 93,75% in cycle I to 100% in cycle II. In addition, students is involved in the activity which is pleasant to study with new athmosphere given. The students’ result score also have great progress. The mean score of the students’ achievement in cycle I is 73,64, while the mean score of the students’ achievement in cycle II is 87,05. Furthermore, the students’ result score have increased from cycle I to cycle II which is percentaged 68.18% to 86.36%. The mean gain is 0.4. In brief, the study which implements RME in calculating operation can improve students’ ability in one of elementary schools at kota Bandung

Studi Kandungan Merkuri dan Arsen dalam Air Laut dan Sedimen di Perairan Teluk Buyat dan Ratatotok

Gold mining activities has been widely recognized using mercury in traditional way and using cyanide in the modernway for fixing (setting) the gold. Usually the gold is fixed with other metals such as arsenic and mercury which arethrown away as a waste. The waste from the gold mining process was thrown away through tailing pipe to the bottomof Buyat Bay and from the gold mining traditional activities are dumped to the river which ended at the RatatotokBay. The aim of this study was eager to know the mercury and arsenic content in the sea water and sediments ofthe Buyat and Ratatotok Bay, and to know the impact of these wastes to the biotic life of Buyat and Ratatotok Bay.This study was done in the period of January to March 2005, during west monsoon. The results indicated that themercury and arsenic content of the sea water quality still below the requirement of Ministry Decree of sea waterquality standard No. 51/MENLH/2004. On the contrary, the mercury content in the sediment of tailing zone andsome areas in Buyat and Ratatotok Bay are indicated as polluted sediment refer to the Guidelines Asean Marine2004. Moreover, the content of arsenic in the tailing zone, and some areas in the Buyat bay are already categorizedas polluted sediment. The arsenic and mercury content in the sea sediment deteriorating the life of sea biota, and itcan be seen from the decreasing of the benthic index diversity

Analisis Proses Pembelajaran Berbasis Masalah (Problem Based Learning) Matematika Dengan Pendekatan Ilmiah (Scientific Approach ) Di SMA Negeri 1 Jogorogo Kelas X Kabupaten Ngawi

The purpose of this research was to describe the planning, implementation process of learning undertaken by teachers of mathematics and constraints experienced during the process of mathematical problem-based learning with a scientific approach in class X SMAN 1 Jogorogo. This research was a qualitative study. These subject are taken using purposive sampling. The subjects of this study were the teacher math in class X. Data collection techniques in this study were documentation, interviews and observations. Techniques to validate that the data source triangulation and triangulation time. The data analysis technique used was the concept of Miles and Huberman consists of data reduction, data display, and conclusion. The results showed that the planning process of mathematical problem-based learning with a scientific approach was not maximal yet, seen in the preparation of lesson plans which teachers only see examples of other schools and only see a reference to the syllabus. Implementation of the learning process is done the math teacher in class X SMAN 1 Jogorogo was not maximal yet. Visible in the indicator 5M on core activities are observing, asking, gather information, and communicate their associates have not done all. In observing the activities of students had no difficulty, however, go into the next phase indicator and students are still difficulties in doing so. In the event of problem making students ask questions, lack of motivation and imagination. Collect information on the activities of students also have difficulty in learning resources are used only for math books grade students associate X. At this stage also looks still difficulty in processing information, although sometimes the teacher has given direction that the students tried to process the information that has been obtained. At that last stage quite well in communicating the results, good enough student responses revealed the results even though the teacher had to call one of the students without first. Overcoming the problems found in the process of mathematical problem-based learning with a scientific approach to teacher always gives motivation at any stage of learning and trying to develop a problem-based learning with a scientific approach
