Abstract

The goals of this research were to determine the differences in cognitive learning outcomes, describe the Science Process Skills (SPS), the character, the activities and students’ attitudes toward the use of media ICT simulation as a complement demonstration in the learning measuring instruments. The research has been done in the first semester of 2013/2014 in SMPN 3 Tulang Bawang Tengah. The sample of this research was class VIIA of SMPN 3 Tulang Bawang Tengah randomly. The data was analyzed by using Paired Sample T-Test. The researcher concludes by the use of media ICT simulation as complement demonstration improve that cognitive learning outcomes, to foster character, increase the activity of students and to foster positive attitudes of students toward the use of ICT media simulation as a complement demonstration in the learning measuring instruments.Tujuan penelitian ini untuk mengetahui hasil belajar ranah kognitif, mendeskripsikan Keterampilan Proses Sains (KPS), karakter, aktivitas dan sikap siswa terhadap pemanfaatan media TIK simulasi sebagai komplemen demonstrasi pada pembelajaran alat ukur. Penelitian ini dilakukan pada semester ganjil di SMPN 3 Tulang Bawang Tengah. Sampel penelitian ini kelas VIIA SMPN 3 Tulang Bawang Tengah menggunakan teknik random. Data dianalisis dengan menggunakan Paired Sample T-Test. Kesimpulan penelitian setelah pemanfaatan media TIK simulasi sebagai komplemen demonstrasi terdapat peningkatan hasil belajar ranah kognitif, menumbuhkan KPS, membentuk karakter, mengembangkan aktivitas siswa serta menumbuhkan sikap positif siswa terhadap pemanfaatan media TIK simulasi sebagai komplemen demonstrasi pada pembelajaran alat ukur.Kata kunci : aktivitas siswa, karakter siswa, keterampilan proses sains, komplemen demonstrasi, media TIK simulasi

Abstract

Reserves of fuel oil, especially those from fossil fuels, are dwindling, while the people's need for fuel oil is increasing. Dependence on fossil fuels needs to be addressed immediately. So it is necessary to develop renewable energy sources as alternative energy to replace fuel oil. One of them is by utilizing bioethanol as an alternative. The process of making bioethanol involves a distillation process. In this study, the design and performance test of an electric distillation apparatus was carried out by utilizing molasses as a raw material for making bioethanol. The aim is to determine the quality of the alcohol content in bioethanol which is processed using an electric distillation apparatus. Electrical distillator testing includes functional tests and performance tests. Functional testing is done by testing the components used in the tool so that it can be seen whether the tool is functioning properly. Meanwhile, the performance test of the electric distillator is an automatic performance test of a tool to produce bioethanol. The performance test procedure of the electric distillator was carried out using a bimetallic thermostat of 76ºC and 85ºC, to measure the distillation time and determine the alcohol content in bioethanol. From the results of the study, it was found that for an electric distillator that uses a bimetallic thermostat of 76˚C, the processing time of 70.43 hours produces bioethanol with an alcohol content of 61.7% and an electric distillator that uses a bimetallic thermostat of 85˚C with a processing time of 0.56 hours to produce bioethanol. with an alcohol content of 35%.
