Pumpkin seeds (Cucurbita moschata) in daily life is used only limited to pumpkin seed snack, whereas pumpkin seeds can be processed in various forms. One of them is pumpkin seed tempeh. Tempeh is a traditional fermented food rhizopus sp. made by fermentation and can be used as a food source that has economic value which has high protein. This study aims to determine the protein levels in pumpkin seed tempeh and its use as a learning media. The research type is an explorative descriptive research. Tempe pumpkin seeds were analyzed for protein levels by using micro Kjedhal analysis through three stages, namely destruction, distillation and titration as many as three repetitions. The results show the average protein level of pumpkin seed tempeh is 24.66%. Based on the results of validation tests by a team of experts in content, design and media as well as 20 students, the results of the study are very worthy to be used as a learning media in the form of posters with a feasibility percentage of 81.49%.

The purpose of the research is to find out whether or not the influence of science process skills with the Project Based Learning model on the results of physics learning in grade XI IPA students of SMA Labschool UNTAD Palu. The problem in this study is whether there is an influence of science process skills with project based learning model on the results of students studying physics in grade XI IPA SMA Labschool UNTAD Palu. The benefit of research is to increase students' knowledge of the concepts of physics. To see the success of this study, an initial test was conducted to determine the ability of students in experimental classes and control classes. After that in the experimental class was treated using science process skills with the Project Based Learning model and the control class only used the Project Based Learning model on Business and Energy materials. After the learning is complete, both classes are again given a final test to test the results. Based on the results of both classes, the average scores from the experimental class and control classes were 6,125 and 5.70 for the initial test, while for the final test the average was 13.01, and 12.00. From the analysis of the final test data obtained ttable value of 2.01 while thitung value of 2.48. This shows that thitung value is outside the ho admission area, thus Ho is rejected and H1 is accepted in other words the learning outcomes of the group of students who get the treatment of science process skills with the Project Based Learning model against the results of physics learning in grade XI ipa sma labschool UNTAD Palu at a real level significantly different from the group of students who only use project based learning mode, then it can be concluded that there is an influence of Science Process skills with Project Based Learning Model on Student Physics Learning Results in Grade XI IPA SMA Labschool UNTAD Palu.

This study aims to describe the understanding of the concept of direct current electrical circuits through real and virtual laboratory learning. Subjects and respondents to this study as many as 6 students of the Physics Education Study Program class of 2016 who have programmed basic physics courses. The research instrument used is a three-tier multiple choice diagnostic test with DIRECT 1.1 which is a question of multiple choice with the reason in answering the question, each choice of answers accompanied by a choice of confidence level index in answering or CRI. The test instrument used as many as 24 question numbers. The test result data is then analyzed to determine the percentage of scientific concepts, understand alternative concepts, and do not understand concepts both before practicum and after practicum for each group. Based on the results of the analysis of research data, the concept of students before practicum either follow the learning through the real laboratory first then the virtual laboratory, as well as students who follow the learning through the virtual laboratory first then the real laboratory in the categorized very low, while after practicum in high categorization. Understanding the concept in students who have followed the learning using the real laboratory first then the virtual laboratory is relatively better compared to students who follow the learning using a virtual laboratory first then a real laboratory.
