For the results of learning output on cognitive at the pre-action average score was 65,9 the classical understanding was 65,9 and the classical completed was 52,5%. On cycle I, the average learning output score was 68,7, the classical understanding was 65,9, and 65,9% of classical understanding. On cycle II, the average csore was 88,30, and the classical completed was 87,5%. In cycle I, affective score was average 3,2 (begin to develope), in cycle II, it was 3,55 (habit). Psychomotorscore was average 3,2 (begin to develop) in cycle I and it was 3,8 (habit) in cycle II. To achieve the criterion of classical completed was influenced by the optimum of teacher and student actifity during the learning process using group investigation
Three-Dimensional Model For Cohesive Sediment Transort In Estuary Of Palu River
Get PDFPenelitian ini bertujuan untuk mengkaji dinamika transpor sedimen di Estuari Sungai Palu yang memiliki batimetri curam dan perairan yang dangkal di muara. Simulasi model hidrodinamika dan transpor sedimen dilakukan dengan menggunakan model tiga dimensi ECOMSED yang dibangun oleh HydroQual, Inc., (2002). Simulasi dilakukan dengan menggunakan gaya pembangkit debit sungai dan pasang surut. Hasil simulasi pola arus pada penampang horizontal pada setiap kondisi pasang surut dominan bergerak ke luar teluk, pada penampang vertikal, saat elevasi pasang tertinggi arus bergerak memasuki teluk pada lapisan paling bawah dengan kecepatan arus yang relatif kecil. Perhitungan elevasi permukaan dan kecepatan arus pada penampang vertikal memperlihatkan kesesuaian yang baik dengan data sekunder dan DISHIDROS dan observasi arus. Hasil simulasi transpor sedimen menunjukkan bahwa konsentrasi sedimen pada penampang horizontal dan vertikal dominan dipengaruhi oleh debit sungai dibandingkan dengan pengaruh pasang surut.Penelitian ini bertujuan untuk mengkaji dinamika transpor sedimen di Estuari Sungai Palu yang memiliki batimetri curam dan perairan yang dangkal di muara.

Pengaruh Pembelajaran Kimia Melalui Inkuiri Terbimbing Dengan Pendekatan Saintifik Terhadap Hasil Belajar Dan Sikap Ilmiah Siswa Kelas X SMA Negeri 9 Palu
Get PDFIt has been conducted a research where that aim is to describe the influence of the guided inquiry learning process with the scientific approach on the learning outcomes of and scientific attitudes of student. The population in this study is all students of class X SMA Negeri 9 Palu with academic year 2014/2015. The purposive sampling is used for sampling technique where class XA as an experimental class and class B as a control class. The research design used is the pretest-posttest control group design. Statistical test used is the Mann-Whitney U-Test. Based on the analysis of the calculation of the value of <g>, there is an improvement on learning outcomes of student in the experimental class compared to the control class. Based on statistical test, it is showed that Zcalculation<Ztable at significant level of 0.05, which means that the guided inquiry in chemistry learning through scientific approach gives a significant effect on learning outcomes and scientific attitudes of student in class X SMA Negeri 9 Palu on electrolyte and on-electrolytes solution topic
Pengaruh Urutan Pemberian Materi Pembelajaran (Sequenced) Dengan Model Fragmented dan Model Connected Terhadap Hasil Belajar Siswa Pada Konsep Vektor Di SMA Negeri 1 Palu
Get PDFThe present research is an experimental research studies about the effect of presenting sequenced learning material on the concept of vector through fragmented and connected learning model. The subject of the research consists of 30 students of grade XA who were treated with fragmented model and 30 students of grade XB who were treated with connected model. The data of the two groups of subject were analyzed by using t-test with 5% real level. The result of the experiment indicates that thitung (4,02) is out of acceptance area (2,66). The result indicates that there is the difference result of the students’ learning on concept of vector between those who taught by using fragmented and connected model. Quantitatively, the average score of the students who were treated by using fragmented model is 73, 56 and those who were treated by using connected model is 61,78, it then can be inferred that the fragmented learning model is more effective than connected model use to present the lesson
