Penerapan Pendekatan Pembelajaran STM Materi Sumberdaya Alam Dan Lingkungan Untuk Meningkatkan Hasil Belajar IPA Siswa Kelas IV SD Negeri I Labuan Lobo Tolitoli

Melalui observasi awal kelas IV SD Negeri I Labuanlobo Tolitoli ditemukan bahwa. Siswa kurang menguasai konsep sains khususnya pada pokok bahasan sumberdaya alam dan lingkungan. Siswa belum aktif dalam proses pembelajaran. Hasil belajar tentang Sumber Daya dan lingkungan belum 80% siswa mencapai KKM. Jenis penelitian ini dilaksanakan dengan tujuan untuk mengetahui. Apakah meningakat hasil belajar IPA pada materi sumber daya alam dan lingkungan dengan menggunakan pendekatan sains teknologi masyarakat pada Siswa kelas IV SD Negeri I Labuanlobo Tolitoli. Teknik pengumpulan data menggunakan lembar observasi untuk mengukur tingkat aktivitas siswa dalam pembelajaran tentang sumber daya alam dan lingkungan. Dan tes pilihan ganda bersifat individu pada setiap siklus untuk mengukur hasil belajar siswa. Hasil belajar tentang sumber daya alam dan lingkungan pada siswa kelas IV SDN I Labuanlobo Tolitoli mengalami peningkatan pada setiap siklusnya yaitu pada siklus 1 siswa yang tuntas belajar sebanyak 9 siswa atau 45 %, sedangkan siswa yang belum tuntas belajarnya sebanyak 11 orang atau 55 %. Pada siklus 2 siswa yang tuntas belajar sebanyak 11 siswa atau 90 %, sedangkan siswa yang belum tuntas belajarnya sebanyak 2 orang atau 10%. Aktivitas siswa dalam pembelajaran dengan menggunakan pendekatan STM dapat meningkat yaitu pada siklus 1 rata-rata siswa yang aktif dalam pembelajaran sebanyak 13 siswa atau 65% dengan kualitas baik, sedangkan pada siklus 2 rata-rata siswa yang aktif dalam pembelajaran sebanyak 17 siswa atau 84% dengan kualitas sangat baik. Dengan demikian dapat disimpulkan bahwa penerapan pendekatan pembelajaran STM dapat meningkatkan hasil belajar siswa

Pengaruh Aset, Pemberian Kredit dan Permodalan terhadap Laba Perbankan di Indonesia (Studi Empiris Bank Umum Konvensional yang Terdaftar di Bursa Efek Indonesia)

The purpose of research is to investigate and analyze the influence of Asset , Capital Lending and significant effect on the profit on Banking in Indonesia In Simultaneous or partially. Further research method diganakan role in research with quantitative research method approach that inferential statistics are supported by empirical data obtained from financial statements published by Bank Indonesia through the website www.bi.go.id. and analyzed by multiple regression analysis approach is a portrait of the relationship between the independent variable ( in this case Assets , Loans and Capital ) of the dependent variable ( in the case in is profit ) , with a model of multiple regression equation Y = a + BX1 + CX2 + DX3 , where the variable Y = income , assets X1 = X2 = X3 = credit and Capital , a = intercept or constant and bcd = regression coefficient of each independent variable . By testing the hypothesis that the results obtained are simultaneous F-test result that the calculated F value 1766.834 with a significance of 0.000 . were higher than the value of F table ( one side or α = 0.05 ) is 3.14 ( or 1766.834 > 3.14 ) , so the hypothesis in this study stated that the Assets , Capital Lending and Banking significant effect on earnings simultaneously in Indonesia is proven . And testing hypotheses obtained partial results : no significant effect on the Assets of Banking Income . Non-productive assets significantly influence the Banking Profit is proven , or H0 is rejected . RWA significant effect on Banking Profit is proven , or H0 is rejected . But its influence is negative , where the increasing amount of RWA actually reduce bank profitability and vice versa . Loans disbursed significant effect on Banking Profit is not proven , or H0 is accepted . Credit Loss significant effect on Banking Profit is proven , and significant effect on earnings Equity Bank is proven

Applying Genetic Algorithm on Power System Stabilizer for Stabilization of Power System

This paper the genetic algorithm method is used in Power System Stabilizer (PSS) for power system stability is discussed. Parameters of PSS on generator system in a state determined offline using genetic algorithms and the objective function is based on eigen value system was described in detail. PSS parameters and the location is calculated to maximize damping performance in different operating conditions. Genetic algorithm is a kind of random search algorithm based on the mechanism of natural selection and natural genetics. Genetic algorithms are used as search parameters of the PSS technique, which utilizes genetic operators to find the nearest optimal solution. An advantage of the search with the GA is not trapped in an early convergenc

Pengaruh Hydraulic Retention TIME (Hrt) Dan Konsentrasi Influen Terhadap Penyisihan Parameter Bod Dan Cod Pada Pengolahan Limbah Domestik Greywater Artificial Menggunakan Reaktor Uasb

In urban areas domestic wastewater pollution reaches 60 % and about 75 % of the total volume of domestic wastewater is greywater . As an alternative wastewater treatment, UASB ( Upflow Anaerobic Sludge Blanket ) is an effective waste processing because it has many advantages . Several factors affect the performance of UASB reactors is Hydraulic Retention Time ( HRT ) and influent concentration. In the COD removal and BOD , reactors with HRT 4 hours having the smallest removal efficiency , i.e. by 36 % and 20 % . Reactor reaches the optimum point processing when operated at HRT 12 hours , where COD removal efficiency of 73% and BOD removal efficiency of 66% . In the reactor with medium concentration range ( S ) with an influent COD of 760 - 880mg / L of COD and BOD removal efficiency reached a maximum of 77 % and 75 % . While the smallest efficiency reactor obtained at low concentrations ( R ) with the organic content of the feed ( influent ) of 133-160 mg / L with a COD removal efficiency of 48% and BOD by 44 %
