Abstract

Abstract: The research about development of learning based on Lectora Inspire media has been done. Learning media that developed is Lectora Inspire with using Research Development of modification Four - D model, include stages Define, Design and Development by eliminating Disseminate stage. Data collect technique by validating Lectora Inpire to three validators (media expert and matter experts) and given average score of assessment is 95.63 %. Assessment for practically media test using trial of practitioners (users), there are three teachers and 15 students from class XI. Data analysis of learning media based on questionnaire responses of teachers and students each earned an average score of 96.67 % and 97.3 %. Average score overall validation and trial practitioners of learning media based on Lectora Inspire show that this media is valid and can be use in learning process.Keywords : Learning Media, Lectora Inspire, Rate of Reaction

Abstract

Palm Oil Mill Effluent (POME) is the biggest waste from palm oil production. This liquid waste contain much methane gas (CH4) which has potential as renewable energy, namely biogas. The last stage of processing biogas called methanogenesis reaction, the process of synthesis methane and carbon dioxide. The methanogenesis reaction can be studied by computational studies as learning media source for SeniorHigh School Chemistry with the Chemistry, Life, Universe, and Everything (CLUE) approach. According to learning outcomes of Merdeka Curriculum, the methanogenesis reaction can be used as a learning source forthree chapters in F phase. The chapters areChemical Bonding, Rate of Reaction,and Thermochemistry. The chapter of Chemical Bonding describe hydrogen bonding in acetic acid intermediate species and its effect on the molecular characteristics. The chapter Rate of Reactiondiscuss the result of computational calculation to determine the activation energy (AE). Methanogenesis reaction have two transition states (TS), with AE of each TS are 228.56 kJ.mol-1 and 281.31 kJ.mol-1, while the second stage act as the rate-determining step. The last, for Thermochemistry chapter, the content material is define the quantity of thermodynamic variables on methanogenesis reaction.The value of∆S = 50.14 kJ.mol-1T, ∆G = 139.7 kJ.mol-1, and ∆H =168.84 kJ.mol-1.
