the purpose of this study is to there is influence average learning outcomes students who follow learning to use with those who do not use the guided inquiry model. this research was conducted in class X MAN MODEL 1 MANADO odd semester of the school year 2019/2020. this research is using an experimental method by sampling obtained class X mipa 8 as a 9 as a control class. data collection using learning outcomes test. value is with thitung 3,62 > ttabel 2,011. this means that there is a significant influence on chemical bonding material.
Aglutinin atau lektin adalah protein atau glikoprotein yang mengikat gula secara spesifik. Substans tersebut dapat mengaglutinasi sel karena permukaan sel terdiri atas gula atau sakarida. Halymenia durvillaei, Laurencia obtusa dan Ulva fasciata mengandung aglutinin. Aglutinasi sel oleh aglutinin dapat dihambat oleh gula tertentu yang merupakan gula spesifiknya. Penelitian ini bertujuan untuk menentukan jenis gula spesifik pada aglutinin dari rumput laut Halymenia durvillaei, Laurencia obtusa dan Ulva fasciata. Penelitian ini menunjukkan bahwa gula spesifik pada agglutinin dari ekstrak Laurencia obtusa adalah D-glukosamin, dan Ulva fasciata adalah D(+)-Glukosa.
North Sulawesi is one of the regions in Indonesia which has a wealth of natural resources which is quite abundant, one of the natural potential that can be utilized is White sand. White sand has a composition that is SiO2, CaO, Fe2O3, TiO2, MgO. This study aims to identify the composition of the main components of white sand through XRF testing and the results of extraction of white sand from Marinsow village using the alkaline fusion method, NaOH solution for extracting and crystallizing the formation of silica crystals and tested using XRD testing to determine the crystal characteristics. Extraction and testing processes have been carried out using XRF and XRD on white sand samples taken in Marinsow Village, North Minahasa Regency. The results of the identification of the components of the white sand constituents through XRF testing namely CaO is the largest main component of the white sand compilers in the village of Marinsow which is as much as 89.97%. The content of SiO2 compounds in white sand (Marinsow) is as much as 1.41%. Other components found in white sand from Marinsow village, North Minahasa Regency include MgO as much as 5.85%, SrO as much as 2.31%, Fe2O3 as much as 0.277 %, TiO2 is 0.079%, Cr2O3 is 0.032%, Nb2O5 is 0.0238%, MoO3 is 0.0159%, SnO2 is 0.0082%, Sb2O3 is 0.0079% and RuO4 is 0.0074%. The results of XRD testing on white sand taken in the village of Marinsow give results that white sand has a calcite crystal structure (CaO) and for the SiO2 silica component is quartz.
Tujuan dari Penelitian ini adalah untuk mengetahui Pengaruh Penerapan Video Pembelajaran melalui Google Classroom Terhadap Hasil Belajar siswa X Mipa 4 di SMA N 1 Langowan. Penelitian ini adalah penelitian kuantitatif menggunakan metode experiment dengan menggunakan desain One-Group pretest-posttest design. Populasi yang diambil adalah seluruh kelas X MIPA SMA N 1 Langowan sampel terdiri dari 1 kelas yaitu X MIPA 4 Sebagai kelas eksperimen yang berjumlah 32 orang siswa. Pengambilan data dilakukan dengan memberikan pretest sebelum proses pembelajaran dilaksanakan, dan posttest setelah proses pembelajaran. Data Hasil penelitian yang diperoleh berupa selisih pretest dan posttest pada kelas eksperimen 40,4 dan rata-rata pretest yaitu 47,7, sedangkan rata-rata posttest yaitu 88.1, Sebelum di lakukan uji one sample t test terlebih dahulu di lakukan uji normalitas dan di dapatkan bahwa data terdistribusi normal. Selanjutnya uji melalui uji-t, hasil yang didapat antara kelas eksperimen signifikan yaitu thitung thitung = 18,60 > ttabel = 1,998. Dengan demikian dapat disimpulkan bahwa media pembelajaran Google Classroom yang berisikan Video dapat berpengaruh pada hasil belajar siswa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
