Penerapan Model Pembelajaran Inkuiri Terbimbing Untuk Meningkatkan Aktivitas Dan Hasil Belajar IPA Siswa Kelas V SD INPRES 2 Kayumalue Ngapa
Get PDFThe purpose of this study was to be improve activity and science achievement at fifth grade SD Inpres 2 Kayumalue Ngapa by application of guided inquiry learning model. This study is classroom action research that refers to the Kemmis and Taggart model which consists of four stages namely: planning, action, observation, and reflection. The Learning was done for 3 cycles, each cycle conducted in three meetings. The data was analyse by used qualitative analysis techniques for learning process and quantitative analysis for learning outcomes. Based on classical completeness and absorption, it could be said the achievement of each end of the cycle of 20 students always increasing. Based on the percentage of achieved of students and teacher activity from the first cycle until third cycle the achievement were increased. Achievement of completeness criteria and absorption by way classical, influenced by the optimal activity of students and teachers during the learning takes place
PREDIKSI EROSI DAERAH ALIRAN SUNGAI POBOYA
Get PDFLand rehabilitation in Poboya Watershed should be done on the actual land erosion value in other to avoid intensive land degradation. This research has been conducted to determine and map erosion hazard level. The erosion hazard level was determinate by using USLE (Universal Soil Lost Equation) formula. The result of experiment showed that the low erosion hazard level in study area 371,2 Ha (5,5%), medium 3.483,4 ha (51,9%), high 11,8 ha (0,2%), and very high 2.848,8 ha (42,4%). In general, land with erosion hazard level of very high is located in middle watershed. The high value of erosion in Poboya Watershed area mainly due to the land cover factor and topography. Tolerable erosion in Poboya watershed 371,1 ha (5,51%) and intolerable 6.344 ha (94,4%). Land area Poboya Watershed 6.715,06 ha and total erosion 2.643.587,48 ton.yr-1 while tolerable erosion 73.259,97 ton.yr-1

Get PDFThe aims of this research are: (1) analyzing the supplies effect, the effective working days, the catching trip, the fishing equipment which affecting the fishermen result in catching fish of Bantaya Village, Parigi Sub-District in Parigi Moutong Regency, (2) Analyzing the fishermen income in bantaya Village Parigi Sub-District in Parigi Moutong Regency. The sample of this research is fishermen in Bantaya village, and then the method used was census method. The instruments of data collection were observation and interview which analyzed through multiple linear regression and income analysis. The result of the research by using multiple linear regression showed that coeffcient of determination (R2) is 0.849. Going through Ftest, it shows that Fcounted = 80.034 > Ftable = 3.695 on α = 1%, it proves that Null hypothesis was rejected. It means that the independent variable (1n X1), labor (1n x2), the number of catching trip (1n X3) the fishing equipment (D) simultaneously affects the result of catching fish in bantaya Village Parigi Sub-District in Parigi Moutong Regency. Furthermore, the fisheries’ income in Kelurahan of Bantaya with the production cost is Rp. 26.208.658,-/ month, which consists of fixed amount is Rp. 16.101.847,-/month and the variable cost is Rp. 10.106.810,-/month, the amount income is Rp. 53.881.207,-/month, so that the amount before sharing profit is Rp. 27.672.549,-/month, while income after sharing profit is Rp. 3.231.213,-/month
