Abstract

The purpose of this study was to develop valid, practical, and effective number bowling media to improve children's counting skills at IT Al-Kahfi Kindergarten, Kemu Village. The research method is research and development with the ADDIE research model (Analysis, Design, Development, Implementation, and Evaluation). The one to one trial stage amounted to 5 students and a small group trial with 10 students. Data collection techniques using observation, questionnaires, interviews and documentation. The data analysis technique uses validity test, practical test, and effectiveness test. The results showed the validity of material experts 87.5 very valid category and media experts 92.5 very valid category. Practicality test of number bowling media based on teacher response questionnaire, 86.6 very practical category and in the student response trial using one to one 91.28 categorized as very practical and 89.63 categorized as very practical in the small group trial. The effectiveness test is seen from the hypothesis test using the t-test, obtained tcount = 103.439 while for ttable = 2.313. So it can be concluded that tcount> ttable then Ha is accepted and Ho is rejected. It is concluded that the number bowling media to improve children's counting skills is valid, practical, and effective to use in learning.

Abstract

Eucalyptus plants (Melaleuca cajuputi) are one of the essential oil-producing plants that are important for the essential oil industry in Indonesia, the potential of wood oil plants in Indonesia is quite large, starting from the Maluku, Bali, and Java areas as one of the ingredients for health or pharmaceutical products. The purpose of this study is to determine the content of essential oils in eucalyptus oil using FTIR. To determine the characteristics of essential oil compounds in eucalyptus oil is carried out by characterizing FTIR from the tests carried out, it is hoped that the characterization of essential oil compounds in eucalyptus oil can be obtained. The results of the study contain eucalyptus oil containing the main component, namely 1,8-sineol. This is indicated by the appearance of longitudinal vibrations in the functional groups in the function groups -CH2 at wave numbers 1463.27 and 1361.15 cm-1, -CH3 at wave number 1361.15 cm-1, C-H alkanes at wave numbers 2965.27 and 2920.29 cm-1, and C-O at wave numbers 1214.72, 1167.29, and 1078.61 cm-1 there are 1,8-sineol compounds [2]. The C-O group at wave numbers 1214.72, 1167.29, and 1078.61 cm-1 is an ether group. The quality of eucalyptus oil is determined by the content of sineol, the higher the sineol content, the higher the quality value.
