Abstract

The research has created the module of mole concept based on structured inquiry with interconnection of multiple representation and determined the validity and practicality of the module. The research type was Research and Development (R&D). The development model was 4-D models that consist of four steps: define, design, develop, and disseminate. The research was limited on develop step. The instrument of the research was questionnaire form that consist of validity and practicality sheets. The module was validated by 5 validators. Practicality module was tested by 2 chemistry teachers and 28 students of grade XI MIA 5 at SMAN 4 of Padang. Validity and practicality data were analysed by using the kappa Cohen formula. The moment kappa average of 5 validators was 0,95 with highest validity category. The moment kappa average of teachers and students were 0,89 and 0,91 praticality with high category. The result of the research showed that the module of mole concept based on structured inquiry with interconnection of macro, submicro, and symbolic representation was valid and practice to be used on the learning chemistry

Abstract

Inulin is natural polymer belong to a class of carbohydrates. Inulin has effect the best of prebiotic. Inulin is fermented by Bifidobacteria and Lactobacilli quictly and easy. Major product of  fermentation is short chain fatty acids (SCFA) and L-laktate.  SCFA is an important function of the large intestine. SCFA influence immune function, heart health, cancer prevention. SCFA decrease colonic and faecal pH, so support growth of Lactobacilli and Bifidobacteria, inhibits growth of patogen bacterial. SCFA can influences metabolism of lipid and glucose. Inulin can increase absortion of Ca, Mg and Fe. Key words :    inulin, prebiotic, probiotic, SCFA

Abstract

The aim of the Community Partnership Program (PKM) service activity is to increase teacher competency in making learning media of ICT-based PowerPoint-iSpring with emphasis on three levels of representation. The method of PKM was lectures, demonstrations and workshops. The lecture and demonstration methods were used to deliver the topics i.e ICT and internet terminology, three levels representation and 21st century learning, making learning media of PowerPoint-iSpring, using Camtasia software. The practice includes quick tricks of editing images from ebooks, google image, video learning and transferring them to PowerPoint-iSpring learning media.Workshops were to make PowerPoint-iSpring media accompanied by videos of learning, animation of chemical, physical and biological concepts. This activity can improve the knowledge and skills of chemistry teachers using standard chemistry, physics and biology e-books, videos of learning and animation from internet. This community service activities can improve the knowledge and skills of chemistry teachers in integrating a variety of learning resources that can be used to create ICT-based PowerPoint-iSpring with emphasizing on three levels of representation

Abstract

The aim of the Community Partnership Program (PKM) service activity is to increase teacher competency in making electronic electronic Student Work Sheets (e-LPKD) using flip book makers with an emphasis on three levels of chemical representation. The method used is lectures, demonstrations and workshops. The lecture and demonstration methods are used to deliver the topics i.e ICT and internet terminology, industrial revolution 4 and three levels of chemical representation. The practice includes quick tricks of editing images from general chemistry books and transferring them to LKPD. Workshops are to make e-LKPD using a flip book maker accompanied by videos of learning chemistry, animation of chemical concepts. This activity can improve the knowledge and skills of chemistry teachers using standard general chemistry e-books, videos of chemistry learning and chemical animation from internet. This community service activities can improve the knowledge and skills of chemistry teachers in integrating a variety of learning resources that can be used to create ICT-based e-LKPD by emphasizing on three levels of chemical representation.

Abstract

Increasing the functional value of yogurt can be done by combining prebiotics with probiotics, known as yoghurt set synbiotics. This study aims to determine the effect of adding inulin chicory to the organoleptic synbiotic yoghurt set. This research is an experimental research. The yoghurt synbiotics made have variations in inulin concentrations (0.1%, 0.3%, 0.5%). Preparation of yoghurt synbiotic set was carried out at an incubation time of 20 hours, temperature 37°C. The analysis of the organoleptic test results showed that in the addition of 0.3% inulin, there was a significant difference in the aroma and texture of the yogurt synbiotic set, while the color was not significant between the comparison yogurt with the addition of 0.3% inulin.
