Abstract

Abstrak: Tujuan penelitian untuk meningkatkan hasil belajar siswa dengan metode bermain peran dalam pembelajaran PKn di kelas VB SDN 24 Pontianak Tenggara. Metode penelitian yang digunakan metode deskriptif, bentuk penelitian tindakan kelas, dan bersifat kolaboratif. Subjek penelitian guru dan siswa 28 orang. Hasil penelitian terdiri dari III siklus (1) kemampuan guru merancang pembelajaran dari siklus I yaitu, 3,8 siklus II 3,85 dan siklus III 3,9. (2) kemampuan guru melaksanakan pembelajaran dari siklus I yaitu, 3,5 siklus II 3,84 dan siklus III  dengan rata-rata 3,92. (3). Hasil belajar siswa diperoleh dari siklus I yaitu, 79,46 siklus II 86,78 dan siklus III 91,42. Dari data yang diperoleh bahwa dengan menggunakan metode bermain peran dapat meningkatkan hasil belajar siswa   Kata Kunci : Peningkatan, hasil belajar, metode bermain peran. Abstract: The aim of research to improve student learning outcomes with teaching methods play a role in Civics class VB SDN 24 South East Pontianak. The research method used descriptive methods, forms of action research, and collaborative. The research subject teachers and students 28 people. The results of the study consisted of the third cycle of (1) the ability of teachers to design lessons learned from the first cycle ie, 3.8 second cycle and third cycle 3.9 3.85. (2) the ability of teachers to implement the lessons learned from the first cycle ie, 3.5 second cycle and third cycle of 3.84 with an average of 3.92. (3). Student learning outcomes are obtained from the first cycle, second cycle 79.46 86.78 91.42 and third cycle. From the data obtained that by using the method of role playing can improve student learning outcomes   Keywords: Improvement, learning outcomes, methods play a role

Abstract

Utilization of Bagasse Cellulose for Ethanol Production through Simultaneous Saccharification and Fermentation by Xylanase. Bagasse is a solid residue from sugar cane process, which is not many use it for some product which have more added value. Bagasse, which is a lignosellulosic material, be able to be use for alternative energy resources like bioethanol or biogas. With renewable energy resources a crisis of energy in Republic of Indonesia could be solved, especially in oil and gas. This research has done the conversion of bagasse to bioethanol with xylanase enzyme. The result show that bagasse contains of 52,7% cellulose, 20% hemicelluloses, and 24,2% lignin. Xylanase enzyme and Saccharomyces cerevisiae was used to hydrolyse and fermentation in SSF process. Variation in this research use pH (4, 4,5, and 5), for increasing ethanol quantity, SSF process was done by added chloride acid (HCl) with concentration 0.5% and 1% (v/v) and also pre-treatment with white rot fungi such as Lentinus edodes (L.edodes) as long 4 weeks. The SSF process was done with 24, 48, 72, and 96 hour’s incubation time for fermentation. Variation of pH 4, 4,5, and 5 can produce ethanol with concentrations 2,357 g/L, 2,451 g/L, 2,709 g/L. The added chloride acid (HCl) with concentration 0.5% and 1% (v/v) and L. edodes can increase ethanol yield, The highest ethanol concentration with added chloride acid (HCl) concentration 0.5% and 1% consecutively is 2,967 g/L, 3,249 g/L. The highest ethanol concentration with pre-treatment by L. edodes is 3,202 g/L.
