Abstract This research aims to find out the increase student learning outcomes on the subject of hidrocarbon with the application of active learning type of Group to Group Exchange (GGE) of grade X at Senior High School 10 Pekanbaru. This type of research is experimental research with data retrieval time from the date of 18 May to 1 June 2013. The samples in this research are students of class X2 as experimental class and class X1 as control class selected after conducting test of homogeneity. Techniques of data collection in this research was to test the homogeneity as initial data on the material previously, documentation, observations, pretest and posttest as final data. Final data analysis in this research using test "t". From the calculations, t count = 4.59 at significant level of 5% obtained t table = 1.66, showing that t count≥ t table so that Ho is rejected and Ha accepted. The magnitude of the average normalized gain <N-GAIN> student learning outcomes experimental class was 0.75 which includes high category, and for the control class is 0.70 which included a middle category. Based on the results of these data analysis, it is concluded that an increase in learning outcomes on the subject of hidrocarbon with the application of active learning type of Group to Group Exchange (GGE) of grade X at Senior High School 10 Pekanbaru.

Abstract

Vitamin C is one of the vitamins that the body needs to increase immunity in warding off all forms of disease. One of the fruits that contain vitamin C is srikaya fruit. Srikaya fruit is a plant belonging to the genus Annona originating from the tropics. Srikaya fruit is analyzed for its vitamin C content in order to increase the immunity of the community during the COVID-19 pandemic. The method used is a laboratory experiment with the iodometric method. The result is that srikaya fruit contains a fairly high amount of vitamin C, with the average vitamin C levels in the srikaya fruit sample being 2.58%, 2.503% and 2.66%, respectively, while the average vitamin C content in the srikaya fruit sample is 2.581%. And during this pandemic, we should consume a lot of food and fruit with vitamin C to increase the body's immunity, so that it can be developed to the next stage of further and more effective research.

Abstract

Biodiesel can be production from waste cooking oil catalyzed by base heterogeneous catalysts. One type of heterogeneous base catalyst is CaO. CaO can be produced from mollusc animal waste, one of which is snail shell waste (Achatina fulica). The main constituent of snail shell waste (Achatina fulica) is a calcium oxide compound (CaCO3) which can be decomposed into CaO at high temperatures. In this study, a temperature of  900 oC for 10 hours was used to convert CaCO3 compounds into CaO compounds. Biodiesel production using CaO catalyst on the mole ratio of oil: methanol 1: 6, 3 g weight of catalyst, the reaction temperature at 60 °C, the reaction time of 3.5 hours, and stirring speed of 250 rpm with biodiesel results obtained at 84,28%.
