Abstract

AbstractThis research was instigated bythe emergence of environmental pollution problems caused by laundry waste.  The problem could be solved by processing the waste using the active carbon of pineapple crown, by utilizing adsorption properties found on Colloid material.  The research findings would be as the learning resource.  This research aimed at producing the valid and practical learning resource.  The learning resource product developed was such interactive multimedia using Lectora Inspire software.  This research was a Research and Development (R&D) with Define, Design, and Develop steps.  This research was administered at State Senior High Schools 1 and 2 Bangkinang Kota.  Validity and practicality test questionnaires were the instruments of collecting the data, and the data were analyzed by using descriptive qualitative and quantitative analysis techniques.  The research findings stated that the active carbon of pineapple crown contained 5% water content and iodine absorption was 482.334 mg/g.  The reduction of Phosphate content oflaundry waste after being processedwith the active carbon of pineapple crown was 40.7%.  The learning resource produced in the form of interactive multimedia contained 93.51% validity (very valid) and 87.57% practicality (very good).  Based the findings, it could be identified that the learning resource tested was proper and practical to be used as the learning resource. Keywords:  The Active Carbon of Pineapple Crown, Laundry Waste, Learning Resource, Interactive Multimedia of Lectora Inspire, Adsorption

Abstract

Abstract This research was an experiment—instigated by the lack of students’ activeness in the teaching learning process. This research aimed at informing that Predict Observe Explain (POE) learning model effected students’ Chemistry learning activity on Electrolyte and Non-Electrolyte Solution material at State Islamic Senior High School of Kuok.  The samples were 29 students of class X.1 (Experimental group) and 31 students of class X.3 (Control group). Interview, normality test of observation sheets, and documentation were the techniques of collecting the data.  T-test was used to analyze the data. Based on the data analysis, tobserved was 2.200 and ttable was 2.00 (tobserved ≥ ttable). It revealed that Ho was rejected. In other words, it showed that there was students’ Chemistry learning activity enhancement on Electrolyte and Non-Electrolyte Solution material at State Islamic Senior High School of Kuok. The influence is counted by using Influence Coefficient (IC) Predict Observe Explain (POE) learning model it is 7,7%. Keywords:Predict Observe Explain (POE)Model, Learning Activity, Electrolyte and Non-Electrolyte Solution
