Abstract

This study aims to determine the increase in learning motivation of class I students in semester II at MIN 3 Boyolali in prayer lessons through picture learning media. This study used classroom action research methods and used three cycles of action with the stages of planning/preliminary design, action, observation and reflection. The subjects of this study were class I MIN 3 Boyolali Academic Year 2022/2023. The data collection method uses 2 techniques, namely observation techniques and closed questionnaires. The data obtained were analyzed using a percentage, namely dividing the increase in the average score of learning motivation by the average score before giving action and then multiplying it by 100%. The results of data analysis showed that there was an increase in learning motivation in the high category, namely 58.3%. The increase can be explained as follows, namely that there is an average learning motivation score of 24.6 before the action, then it becomes 31.04 or an increase of 26.0% in cycle I, then it becomes 36 or an increase of 47.9% in cycle II, and becomes 39 or an increase of 58.3% in the third cycle. So it can be concluded that the action to increase learning motivation in class I MIN 3 Boyolali has been successful. With an increase in the average score of learning motivation after being given a minimum of 50% action. The actions are 1) Asking students to pay attention to the prayer movements in the media images; 2) Ask students to practice prayer movements together; 3) asking students to practice harmony between prayer movements and readings in groups guided by their respective group leaders.

Abstract

Energi sudah menjadi kebutuhan primer dalam kehidupan sehari-hari. Namun karena jumlahnya yang semakin menipis, para ilmuan mulai mencari sumber energi alternatif. Salahsatunya adalah bahan berbasis selulosa. Kertas HVS bekas merupakan salah satu material yang kandungan selulosanya sangat tinggi dan melimpah, pada tahun 2010 mencapai sekitar 400 juta ton. Sehingga kertas HVS bekas memiliki potensi untuk digunakan sebagai bahan baku dalam pembuatan bioetanol. Hidrolisis selulosa akan menghasilkan glukosa serta bahan-bahan lain seperti furfural. Furfural merupakan salah satuasam karboksilat dan fenol yang bersifat meracuni mikroorganisme pada saat proses fermentasi. Arang aktif dapat digunakan sebagai adsorben yang efektif untuk menghilangkan berbagai kontaminan organik dan anorganik. Arang aktif juga dipengaruhi oleh reagen aktivasi yang digunakan. Dalam penelitian ini digunakan reagen aktivasi KOH dan K2CO3 dengan metode pemanasan microwave dan autoclave. Diketahui bahwa semakin tinggi konsenterasi reagen aktivasi maka semakin tinggi pula kadar bioetanol yang terbentuk karena luas permukaan arang aktif yang semakin besar. Perolehan bioetanol yang paling tinggi yaitu pada konsenterasi reagen aktivasi 3,5N KOH dan 3,5N K2CO3.
