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

Upaya Meningkatkan Hasil Belajar Siswa melalui Penggunaan Media dan Metode Pemberian Tugas di Kelas Ivb Sdn 007 Bagan Besar Dumai

This study aimed to describe the learning outcomes through the use of maps. The subjects were students of class V SD 007 Bagan Besar, Dumai with held consisting of two cycles. Improved learning outcomes in terms of four categories, namely absorption, the effectiveness of learning, mastery learning completeness students both individually and classical completeness and thoroughness of learning outcomes. The instrument used for data collection is an oral test and a written test in the form of worksheets that is done after the process of learning. The results showed absorption learning outcomes on average 80% considered very good, very effective learning effectiveness categorized by an average of 8.5. While the completeness of student learning outcomes expressed complete 100%

Pengaruh Konsentrasi Influen Dan Debit Terhadap Penyisihan Parameter Bod Dan Cod Pada Pengolahan Air Limbah Domestik Artificial (Grey Water) Menggunakan Reaktor Uasb

UASB anaerobic digestion is one of the most suitable used to treat waste especially grey water. UASB (Up-flow Anaerobic Sludge Blanket) is one of a kind anaerobic wastewater treatment that operated continuously, sewage flowed vertically in the UASB fermenter from the bottom toward the top pass Sludge Blanket which there is microbial decomposition of waste in it. Domestic waste has a huge contribution to the contamination ofwater. Domestic waste consists of black water and grey water, but grey water is the most polluting water and there is a few efforts to manage it recently. This studyusingartificialwastethat has beenadapted tothe originalgrey waterwith thehighestrangein the Gabahan Village, andBSB Neighborhoodis thelowestconcentration rangewhichwill beanalyzed then byvarying theinfluent flow and concentration so that the qualityof theinfluentandeffluentof eachBOD5andCOD parameter will be known. There are 5 variations of concentration and flow for 25 reactors which extracted the most optimum removal efficiency within designated parameters BOD5 and COD. The results showedthat by varying the influentconcentration, the range of valuesof CODremoval efficiencyreached40-77% and 38-75% ofBOD5allowance. Themiddle concentration being the most optimum in the BOD5 allowance with percentage 0f 75% and COD by 77% andthe most optimum flow variations on0,405L/ hourwiththe longestHRTto 12Hours. Results of the research showedthat the higher flow will decrease the removal efficiency of BOD5and COD

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 %
