The research focused on the influence of discovery learning. The purposes of this research were to reviewing the effect of discovery learning model to student\u27s learning motivation in MAN Bondowoso and to knew the effect of discovery learning\u27s model for student\u27s physics learning outcomes in MAN Bondowoso. The kind of this research was experiment by posttest only control design. Population of the research was class X at Islamic Senior High School Bondowoso. Technique to collect the data were observation, interview, documentation, test and questionnaire. Technique of data analysis were decriptive and Independent Sample t-test with SPSS 16. The result of independent sample t-test to student\u27s learning motivation showed  value 0,0305≤ 0,05. While the result of independent sample t-test to learning outcomes showed  value 0,000 ≤ 0,05. Based on that result could be concluded that: (1) discovery learning model significantly took effect to student\u27 learning motivation in MA; (2) discovery learning model significantly took effect to student\u27s physics learning outcomes in MA.   Keywords: discovery learning model, learning motivation, student\u27s learning outcom

Penerapan Model Inkuiri Terbimbing (Guided Inquiry) Dalam Pembelajaran Fisika SMA Di Jember (Studi Pada Keterampilan Proses Sains Dan Keterampilan Berpikir Kritis)

The research aimed to describe of science process skills students and to assess the effect of guided inquiry learning to physics critical thinking skills students. The research used true experimental with randomized control group only design. Data collection methods used in this research is test, observation, documentation, and interview as supporting data. The data of student\u27s critical thinking skills were analized by using Independent Sample T-Test in SPSS 22. The results showed 1) guided inquiry learning can be used to train students\u27 science process skills. The term proved by percentage increase in science process skills of students from the first meeting until third meeting and if the categorized in science process skills criteria already quite good, 2) guided inquiry learning significant effect on students\u27critical thinking skills. It can seen from the significant value (one-tailed) of 0,0015 or ≤ 0,05. The research can be concluded that: the students\u27 science process skills during guided inquiry learning was classified into good criteria and the student\u27s critical thinking skills after learning physics using guided inquiry model better than the student\u27s critical thinking skills after learning physics using the usual model in Senior High School

Pengaruh Lama Perendaman Tio2 Dalam Dye Sensitizer Ekstrak Daun Tembakau (Nicotiana Tabacum L) Terhadap Efisiensi Dye Sensitizer Solar Cell (Dssc)

Energy is one of the important things in the world, especially Indonesia,which has high people population. Energy consumption are dominate ofunrenewable energy, such as fuel and gasses. In other side, unrenewable energy wasrestricted, so we need to find the other energy source. Renewable Energy can helpsUnrenewable energy to complete national energy consumption such as solar cell.DSSC (Dye sensitized solar cell) is a kind of inexpensive and eco-friendly solar cellthat base on photoelectrochemical reaction. The purpose of this research is toobserve the affect of TiO2 immersion in tobacco leaf extract (Nicotiana tabacum L)as dye sensitizer to current, voltage and eficiency of Dye Sensitized Solar Cell(DSSC). The stage of this research are dye preparation, counter-electrodepreparation, TiO2 preparation, electrolyte and assembly process. The variable thatuse in this research are 30 minutes, 60 minutes, and 90 minutes of immersion time.The result indicate that the immersion hasaffect to DSSC output. The 60 minutes ofimmersion can result higher output at 12 P.M with 729,2 Watt/m2 illuminance,which are 173,6 mV in voltage and 0,621 mA in current. It also produce 0,0493%efficiency at the same time. The result indicate that the immersion hasaffect to DSSCoutput such as current, voltage and efficiency
