Abstract

Abstract One of the lesson while student have to learn it there are ranks and line aritmatics number. Base from that, writer do research with purpose know are the cooperative learning model STAD type can improve learning result in the ranks and line aritmatics number in class IX SMPN 1 Labuhanhaji South Aceh and for know the students activies during the learning process with cooperative learning model STAD type in ranks and line aritmaticsc number at class IX SMPN Labuhanhaji South Aceh. Subject that take from the research are students at class IX4 SMPN 1 Labuhanhaji South Aceh. Data was collected by do test and observation when learning implementation that do in two cycle activity. Data analysis in this research use statistic descriptive technic that is determine the average of the test every in the end of the syclus with count the presentase the students learning success. The result research show that model application of cooperative learning STAD type can during learning at ranks and line aritmetics at class IX SMPN 1 Labuhanhaji South Aceh. This thing can see from the raising completeness learning in every siclus. Clasical completeness in siclus I is 81,82% with the average value 79,24, classical completeness in siclus II is 90.91% with average value 86,21 or increase 8,08% equivalent with average value in siclus I. Research result show too that students activities the during learning with cooperative model STAD type in ranks and line aritmatics number at class IX SMPN 1 Labuhanhaji South Aceh more active. That thing sign with active students that focus on the teacher’s explanation, active student group discussion, the braveness of students in questioning, answer quation and comprehend subject.Keywords: The Cooperative Type STAD, result student learning

Abstract

Study on enhancing the solubility of clay containing magnesium of localproduction (Indrapuri) has been conducted. The clay is commercially available and named as “kieserite” produced by local companies. The sample was taken randomly from fertilizer shops and analysed with AAS and XRF methods. XRF data of local kieserite showed the dominated chemical content; MgO(33.19%); SiO2(33.11%); CaO(1.90%);Al2O3 (5.77%) and Fe2O3(6.32%). The MgO content is higher than that of magnesium sulphate monohydrate (CAS No.: 14168-73-1) which is only 28%. The concentration of soluble magnesium ions of local kieserite naturally soluble was 0.0186% which is very low compared with the soluble magnesium of magnesium sulphate monohydrate (CAS No.:14168-73-1) which is 25%. The Enhancing the magnesium solubility was done by soaking the local kieseriteinto 0.1-0.5M HNO3 before neutralized with NH4OH or mixing the local kieserite with in alluvial, entisol, red-yellow-podsolik (RYP) soils with and without addition of 0.1-0.5M of (NH4)2SO4. The amount of dissolved magnesium of kieserite was found morein entisol soil than the other type of soils. The concentration increased up between 0.59-1.00% along with the incrementof (NH4)2SO4 concentration (0.1-0.5 M). Both in entisol soil and in 0.1 M of (NH4)2SO4, the dissolved magnesium ion increased up to 0.825% but decreased at higher concentration of (NH4)2SO4

Abstract

Cara menyikapi suatu penyakit saat ini sangat berubah. Masyarakat saat ini mengharapkan semua perawatan, bahkan atas kelainan yang paling berat pun, harus berhasil. Sementara itu, masyarakat saat ini juga semakin mandiri. Pada umumnya masyarakat sadar bahwa berbagai sakit ringan biasa, seperti pilek atau diare, tidak memerlukan bantuan ahli kesehatan atau pengobatan yang rumit. Masalah bagi masyarakat yang tidak terlatih secara medis adalah bahwa keluhan semacam sakit kepala atau batuk dapat merupakan petunjuk awal adanya sakit yang serius. Sejauh mana seseorang cukup aman untuk mengatasi sendiri sebuah masalah? Kapan mereka harus menelepon dokter atau meminta bantuan layanan kesehatan? Kapan mereka harus membawa si sakit ke unit gawat darurat sebuah rumah sakit? Dengan meluasnya teknologi piranti  mobile di masyarakat, maka mendorong pemanfaatan teknologi informasi tersebut untuk membantu dalam bidang kesehatan. Khususnya sebagai alat bantu untuk menyampaikan informasi dan mendiagnosa gejala penyakit yang diderita bayi. Hal ini akan membantu para orang tua dalam melakukan pencegahan dan pengobatan pada bayi mereka yang sakit.
