Perbedaan Hasil Belajar IPS Ekonomi Menggunakan Pendekatan Reciprocal Teaching dengan Konvensional Siswa Kelas VII SMP Negeri 20 Padang

This research was motivated by the low economy class student learning outcomes SMP N 20 Champaign Academic Year 2013/2014. This is caused by the lack of activity of students in the learning process. This study aims to determine the differences in learning outcomes of students with the application of economic models Reciprocal Teaching learning with conventional learning on SMP Seventh Grade 20 Padang. This research is an experimental study. The study population was a class VII student of SMP N 20 Champaign school year 2013/2014. Samples were taken by purposive sampling technique, was selected as the class VII6 VII7 experimental class and the class as a control class. The instrument used is the observation sheet achievement test. Data analysis techniques to test the hypothesis is to test Z. Based on the analysis of data obtained an average value of 80.73 experimental class and control class average of 73.37. The results of data analysis known Z count value is greater than 2.091 price 1.960 Z table which means the hypothesis is accepted at significance level α = 0.05. It can be concluded that the learning outcomes of students with the application of economic models Reciprocal Teaching learning better than economics student learning outcomes in the conventional learning process in class VII SMP N 20 Padang. To the principal, especially economic studies teachers are expected to implement the learning model Reciprocal Teaching to improve student learning outcomes. Students are also expected to be more motivated and more active in the learning economy if this strategy is applied. For other researchers who are interested in using learning model Reciprocal Teaching please apply with variations of different tests, different yng school and different subjects

Penerapan Model Cooperative Learning Tipe Picture and Picture Dalam Meningkatkan Motivasi Belajar Anak Sekolah Dasar

This study aims to determine (1) the effect of the cooperative learning modelon learning motivation (2) the effect of cooperative learning models on learning outcomes (3)the relationship between motivation and learning outcomes that are learned using the model cooperative learning. This research is a quasi-experimentalCooperative learning is known as open learning. However, cooperative learning is more than just group learning or group work because in cooperatives there is a cooperative drive or task that allows open interaction and effective interdependence among group members.Cooperative learning can also be interpreted as a shared task structure in an atmosphere of togetherness among fellow group members. Cooperative learning is a learning model where the system learns and works in small groups that gather 4-6 people collaboratively so that it can make students more enthusiastic in learnin

Pengaruh Pemberian Amelioran terhadap Laju Infiltrasi pada Tanah Psamment dan Pertumbuhan Serta Hasil Tanaman Jagung (Zea Mays)

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ameliorant terhadap laju infiltrasi tanah serta pertumbuhan dan hasil tanaman jagung (Zea mays) pada Psamment. Penelitian ini dilaksanakan di Nagari Katapiang, Kecamatan Batang Anai Padang Pariaman, dan analisis tanah di laboratorium Jurusan Tanah Fakultas Pertanian Universitas Andalas. Penelitian ini dilaksanakan pada bulan April hingga Oktober 2018 menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 4 ulangan. Data yang diperoleh dianalisis dengan statistik dan dilanjutkan dengan uji DNMRT taraf 5% untuk nilai F yang berbeda nyata. Perlakuan yang diberikan adalah A = Kontrol, B = Mulsa jerami padi (10 ton/ha), C= Biochar sekam padi (20 ton/ha), D = liat (20 ton/ha), E = Mulsa jerami padi (10 ton/ha) + liat (20 ton/ha), F =Mulsa jerami padi (10 ton/ha) + Biochar sekam padi (20 ton/ha), G = Biochar sekam padi (20 ton/ha) +liat (20 ton/ha), H = Mulsa jerami padi (10 ton/ha) + Biochar sekam padi (20 ton/ha) +liat (20 ton/ha). Hasil penelitian menunjukkan bahwa penambahan perlakuan kombinasi biochar sekam padi, tanah liat, dan mulsa jerami padi terdapat peningkatan tertinggi terhadap nilai TRP yaitu sebesar 23,23%, kandungan bahan organik sebesar 2,78%, dan kadar air tanah sebesar 6%, dan penurunan nilai BV sebesar 0,47 g/cm3. Penurunan nilai laju infiltrasi tertinggi berada pada perlakuan kombinasi mulsa jerami padi, liat dan biochar sekam padi dengan nilai sebesar 506,6 mm/jam dibandingkan kontrol sebesar 994,7 mm/jam, namun masih dalam kriteria yang sama. Penambahan pelakuan kombinasi mulsa jerami padi, liat dan biochar sekam padi pada Psamment dapat meningkatkan hasil tanaman jagung sebesar 11,05 kg/plot jika dibandingkan dengan kontrol sebesar 6,72 kg/plot
