Abstract

This study aimed to improve student learning outcomes in Mathematics class IV at Kinilow Catholic Elementary School through the application of IT-based media. The type of research used is Classroom Action Research. Data collection techniques are observation, tests and documentation. The subjects of this study were 10 students of class IV of Kinilow Catholic Elementary School. The results of the study show that the application of IT-based media can improve student learning outcomes. As for the first cycle, student learning outcomes obtained a percentage of 62.5%, then learning outcomes in cycle 2 obtained a percentage of 86.5%. Implementation of cycle 2 by perfecting things that are lacking in cycle 1, student learning outcomes experience a significant increase and are declared successful. Based on the results obtained, it can be concluded that the application of IT-based media can improve the learning outcomes of fourth grade students at Kinilow Catholic Elementary School

Abstract

Research has been carried out on the effect of a catalyst on the yield of transesterification reactions. Pure coconut oil is made mechanically without heating using fresh coconut meat or what is called non-copra, followed by a base-catalyzed transesterification reaction using KOH and NaOH. The purpose of this study was to determine the effect of the catalyst on the yield of the transesterification reaction. The results of the reaction were analyzed by determining the physico-chemical properties and analysis of Gas Chromatography-Mass Spectrometry (GC-SM). The results showed that the average reaction yield with KOH catalyst was 74.3% and 70% NaOH catalyst. The most dominant GC-SM identification results were ethyl caproate 4.12%, ethyl capricate 4.99%, ethyl laurate 54.97%, ethyl myristate 18.49%, ethyl palmitate 8.13%, 9.12 octadecatrin-1-ol 5.24% and ethyl strearate 2.28%.

Abstract

This study aims to develop new learning media using wordwall in chemistry learning, especially in the basic chemical law material at SMA Kr. Eben Haezar Manado, class X. Another objective is to evaluate the feasibility of learning media wordwall in the context of learning chemistry on basic legal material at the school. The research method used is the R&D (Research and Development) method with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Wordwall learning media was developed and implemented in chemistry learning in class X at SMA Kr. Eben Haezar Manado. This study provides several results, namely; The wordwall learning media that was developed received a positive response from students in class X at SMA Kr. Eben Haezar Manado. This media is considered feasible and can be used in chemistry learning basic legal material based on the validity test taken. This research has important implications in increasing the use of wordwall learning media in chemistry learning at SMA Kr. Eben Haezar Manado class X. The use of this media can increase student engagement, facilitate understanding of chemistry concepts, and improve problem solving skills. It is suggested that wordwall learning media can be integrated into the broader chemistry learning strategy in this school.

Abstract

This research using the PTK (Classroom Action Research) method which aims to be able to find efforts to increase student activities through project-based learning models, to improve cognitive abilities and student learning interests. Learners are educational subjects considered active in shaping their chemistry learning achievement. The subjects this study is students of class XI IPA 2 SMA Dian Harapan Holland Village Manado. The focus of this research is the cognitive ability and learning interest of students. The results showed that the cognitive ability and interest in learning class XI IPA 2 SMA Dian Harapan Holland Village Manado there is an increase marked by an increase in the average score from cycle I to cycle III. There was also an increase in the activity of students. Therefore, the implementation of the Project Based Learning Model (PjBL) can provide a good and positive response for students.
