Abstract

Abstrak General purpose of research to improve student learning outcomes through wordsquare model. Descriptive Method in the form of Classroom Action Research, is collaborative. Data collection techniques used are the technique of direct observation and measurement by means of data collection is the Student Worksheet. Setting research with the subject of Teachers / Researchers and students of class IV amounted to 33 students.1) The ability of teachers planning learning wordsquare model experienced an average increase of 0.35 with an average value of 3.64. 2) The ability of teachers to implement learning model wordsquare experienced an average increase of 0.28 with an average value of 3.55. 3) Students' learning outcomes of the wordsquare model experienced an increase in cycles of 8.30 with an average score of 65.04. Conclusion and suggestion: the use of wordsquare model in learning Citizenship Education can improve student learning outcomes, teachers are expected to use wordsquare model in improving student learning outcomes in the future Keywords: Learning outcomes, Wordsquare Model, Citizenship Education.

Abstract

Tujuan penelitian ini adalah: (1) Meningkatkan aktivitas belajar klasikal (2) Meningkatkan aktivitas belajar kelompok. (3) Meningkatkan hasil belajar IPA siswa kelas VIII B SMP Negeri 1 Bangkinang. Metode yang digunakan dalam penelitian ini adalah Penelitian Tindakan Kelas (PTK). PTK ini menggunakan model pembelajaran kooperatif tipe STAD yang terdiri dari 6 langkah yaitu: menyampaikan tujuan dan memotivasi siswa, menyajikan informasi, mengorganisasikan siswa ke dalam kelompok – kelompok belajar, evaluasi, memberikan penghargaan. Hasil penelitian menunjukkan bahwa dengan menggunakan model pembelajaran STAD pada pembelajaran IPA aktivitas belajar klasikal, aktivitas belajar kelompok dan hasil belajar siswa setiap siklusnya mengalami perubahan secara signifikan. Siswa yang aktif secara klasikal dalam pembelajaran mencapai skor 34,57 % pada Siklus I dan pada siklus II mencapai skor 69,14 %. Hasil penilaian aktivitas belajar kelompok siklus I skor A mencapai 40% dan pada siklus II Skor A mencapai 83,33%. Sedangkan hasil belajar siswa pada siklus I pertemuan 1 ketuntasannya mencapai 70,37%, lalu meningkat pada siklus II pertemuan 2 menjadi ketuntasan 96,30%..

Abstract

Lakota Formation is one of the prolific  formations at Teapot Dome Field. The objective of this study is to analyze hydrocarbon potential of Lakota Formation using Amplitude Versus Offset (AVO) analysis. AVO analysis is performed to determine AVO class, intercept (A) and gradient (B) values of Lakota reservoir. This study uses pre-stack 3D gather data and three wells, 17-WX-21, 48-X-28 and 41-2-X-3. The Lakota formation is known to be an oil-bearing sandstone reservoir which supported by log interpretation. Analysis of AVO modelling using well data by crossplotting reflectivity (R) with sin2 θ, shows that the Lakota Formation is in Class IIP for wells 17-WX-21 and 41-2-X-3 and Class II for well 48-X-28. An estimation of AVO intercept and gradient based on the seismic data show that the Lakota Formation is  class II AVO response. A-B plane shows that the pay zones of Lakota formation are fall within hydrocarbon zone, but very close to background trend (wet sands/shale). AVO attributes; A*B and scaled Poisson Ratio  at well location showing difficulty in differentiate the presence of oil and brine. Therefore, it can be concluded that AVO attributes can not distinguish between water and oil zone in Lakota Formation, and therefore we can not determine distribution of oil in the Lakota reservoir.
