Abstract

Abstract This research aimed to determine the reaction kinetics in the process of hydrolysis of pineapple leaves. The experiment was carried out at the temperature (60, 90, and 120 oC) and variation of acid catalyst concentration (0.1; 0.5 and 1 M) by observation reaction time every 30 min. The kinetics model of hydrolysis reactions of pineapple leaves has shown first order reaction with activation energy value to find the concentration of sulfuric acid successively: 0.1 M; -15420 KJ/mol; 0,5 M; 3173.8 KJ/mol; 1 M; 100.53 KJ/mol. The reaction rate constant which produced the highest glucose level was on the use of sulfuric acid at a concentration of 0.1 M at a temperature of 120 oC with glucose levels produced between 26.366.039 ppm to 155.510.778 ppm with k = 0.0106/min. Keywords: glucose; hydrolysis; kinetic model; pineapple leaves

Abstract

ABSTRACT:There had been done a study of Visual Based Learning (VBL) method based on Short Duration Video for Instrumental Chemicals Subject in Chemistry Study Program of Mathematics and Natural Sciences Faculty (MNSF), Islamic University of Indonesia (Universitas Islam Indonesia—UII). VBL method is carried out by creating a short duration video about an instrument according to the syllabus of instrument 1 subject such as AAS, UV-Vis Spectrophotometer, FTIR, GC-MS, and CV. In order to determine the effect of VBL method using, an analysis of scores obtained between the experimental class and the control class is used. To determine the effect of VBL on psychomotor ability is done by observing directly when students do an experiment or practicum. The influence of VBL method application on student motivation was studied by using questionnaire. The results pointed out that the data of both samples (both classes) is homogeneous. T-test results: Two-Sample Assuming Equal Variances showed that there is a significant difference in the final scores mean between the experimental class and the control class. Based on the mean score it indicates that the VBL method is better while compared to the learning method without VBL. VBL method has a significant effect on students motivation andpsychomotor ability when it is viewed from observation of practicum and the score of practicum. The conclusion is that the VBL method is able to increase students' motivation and psychomotor ability in the Instrumental Chemistry subject.Keywords: Learning, video, chemistry, instrumentalReceived: 20 June 2017, Revised: 13 August 2017, Accepted: 1 September 2017

Abstract

This activity is a training activity on strengthening understanding of chemistry through the Learning Management System (LMS). The basis for taking this activity is based on a needs analysis that has been carried out for the MGMP Chemistry teacher in Bantul Regency. A needs analysis was conducted using non-test instruments in the form of open questionnaires and interviews. Based on the needs analysis results, it shows that most teachers experience problems implementing online learning activities so that learning materials cannot be delivered properly. The method used in this activity is formal socialization—offline. The material presented is related to chemistry and applications and the introduction of LMS. LMS: Teachmint is considered to be able to facilitate students and teachers in teaching and learning activities. Teachers can efficiently conduct video conferences, share material in the form of files/videos, provide deadlines for collecting assignments, and assess and even interact with students using only a single platform. This training received a positive response from chemistry teachers; most teachers agreed to use the platform in chemistry learning
