Abstract

ABSTRACT[Study of Potential of Wild Taro as a Bioethanol Source and Its Implementation in Biological Learning]. This research aims to (1) Determine the carbohydrate content in three types of wild taro. (2) Assessing the effect of different types of yeast on ethanol produced. (3) Assessing the effect of fresh and dried taro tubers on ethanol produced. (4) To find out the difference in learning outcomes of students who use research-based LKS and those who do not use research-based LKS. Bioethanol is obtained through fermentation using yeast. The method used is direct observation and testing of the bioethanol produced. The carbohydrate content of taro kembaang (Colocasia esculenta) in wet conditions is 23.04% and in dry conditions 78.433%. For kemumu forest (Alocasia macrorrhiza) in wet conditions 20.08% and in dry conditions 79,725. For black taro (Xantomonas nigrum) 23.20% in wet conditions and in dry conditions 72.622%. Traditional yeast produces more ethanol than packaging yeast (Fermipan). More ethanol is produced in taro in dry conditions, namely kembaang taro (Colocasia esculenta) 2.30%, kemumu taro forest (Alocasia macrorrhiza) 2.64% and black taro (Xantomonas nigrum) 2.23%. Based on the fresh dried taro tuber, dried taro tubers produce more ethanol. LKS which is a learning resource is used to determine whether there is a difference between the experimental class and the control class using the T test. There are significant differences in learning outcomes between the experimental classes using research-based LKS and the control class that does not use research-based LKS which is characterized by the T test test where th> tk, th = 18.3138 and tk = 2.0085. So that the experimental class learning outcomes are better than the control class. Keywords: Potential; wild taro; bioethanol; learning process.(Received November 6, 2018; Accepted February 9, 2019; Published February 26, 2019) ABSTRAKPenelitan ini bertujuan untuk (1) menentukan kandungan karbohidrat pada tiga jenis talas liar.

Abstract[Improvement of students learning outcomes by applying the video of coffee-mixture identification using UV-Visible Spectroscopy]. The purpose of this study was to evaluate the differences of student learning outcomes on electromagnetic wave materials and how students respond to the learning videos. This research was an experimental research which applies video coffee-mixture identification. The study was conducted in grade X islamic high school consisting of experimental class and control class. Based on the data analysis, the average post-test grade of the experimental class was 82.11 and the mean post-test control grade was 72.88 with tcount = 0,038 which is lower than the value of significance (0,05). The N-gain values of both classes indicate that the experimental class (0.72) is better than the control class (0.61). This suggests the adoption of a coffee-mixture identification video on electromagnetic wave material able to improve greater learning outcomes than control class that did not apply the video to the learning process. The result of questionnaire analysis shows that the student response to video implementation is good, as seen from the average score of responses of students who answered strongly agree at 40% level, while the answer agree at 53.83% level, not agree at 5.43% level and who answered very disagreeing 0.74% of all students. Keywords: Coffee-mixture; UV-Visible spectroscopy; electromagnetic waves; learning video.(Received August 15 2018; Accepted January 25, 2019; Published February 25, 2019) AbstrakPenelitian ini dilakukan dengan tujuan untuk menjelaskan perbedaan peningkatan hasil belajar siswa pada materi gelombang elektromagnetik dan bagaimana respon siswa terhadap video pembelajaran.
