Siswa SMA di Kabupaten Demak
- Authors: Alik Sus Adi, Sugiyanto Sugiyanto, Ani Rusilowati
  Pages: 1 - 6
  Abstract: The purpose of this study was to identify students' learning difficulty profile on the topic of static fluid. The study was conducted in three high schools in Demak. Student learning difficulties profiles were measured using a diagnostic test instrument in the form of multiple open-ended options totaling 13 items. To strengthen the data is done interview with some students. Learning difficulties profiles are diagnosed with five approaches, namely learning objectives, material profiles, prerequisite knowledge, misconceptions, and structured knowledge. The results showed that the percentage of learning objectives for each indicator understood the concept of hydrostatic pressure, comparing the hydrostatic pressure on different liquids, understanding Pascal's legal concepts, understanding the concept of the law of Archimedes in floating, floating, and drowning phenomena, and explaining the buoyant force in a row 58.33%; 75.96%; 57.21%; 81.25%; and 98.56%. Percentage of hydrostatic pressure material profile, Pascal law and Archimedes law were 68.40%; 57.21%; and 89.90%. For prerequisite knowledge with 12% percentage, the percentage of material misconception of hydrostatic pressure and Pascal law are 48.08% and 48.08% respectively and knowledge is structured with 4.07% percentage.

  Pages: 14 - 22
  Abstract: This study aims to describe students’ activities and to determine more effective treatment for improving the concepts achievement between the guided inquiry through real experimental activity or virtual lab activity. This study was a pre-experiment with one group pretest-posttest type. Sampling technique using a purposive sampling. Class experiment 1 was taught by guided inquiry learning through real experiment activities and class experiment 2 was taught by guided inquiry learning through virtual lab activities. Data were collected using test and observation method. The value of experiment class 1 (3,71)> of class experiment 2 (2,10), it means that guided inquiry learning through real experiment activity more effective to improve the concepts achievement of students than virtual lab activity. The gain test of the students' activity development of experiment class 1 was 0,37 (medium) and experiment class 2 was 0,31 (medium), it means that real experiment and virtual lab activities were effective to develop students’ activities.

  Pages: 32 - 41
  Abstract: The purpose of the research is to find out does the testlet test can work as a essay test. This research is an explorative research done to investigate a relatively new phenomenon. In accordance with the research itself, research design used is the One Group Posttest Only Design. Sample is don randomly (Random Sampling). The research is done in SMA Negeri 1 Gombong with the subject of the study is the students of XI MIPA 4 and XI MIPA 6. Based on the research’s result with the t-test analysis, showed that t-value= 1.85 for the XI MIPA 4 students and t-value= 1.89 for the XI MIPA 6 students, with t-table= 1.99. Therefore, from both of the research sample classes, the t-value is lesser that the t-table, so the conclusion is that there is no difference in the students’ cognitive learning outcome evaluated using testlet test and essay test, so testlet test can work as essay test.

- Authors: Irnin Agustina Dwi Astuti, Ria Asep Sumarni, Yoga Budi Bhakti
  Pages: 91 - 96
  Abstract: This study aims to determine the value of elastic modulus of aluminum rod using Video Based Laboratory (VBL) and tracker analysis. The subject discussed about the material of elasticity, because the material is still abstract and still related to everyday life. To overcome these problems then created a learning innovation in the form of innovative visual aids that can attract students' responses in physics learning. Experiments are a planned effort to answer a question by creating an activity under controlled conditions. This tool consists of an aluminum ruler, load, slide, micrometer couplers, couplers, balance sheets, laptops, and cameras. The load used in the research varied as much as six loads with mass of 8.5 grams; 16.3 grams; 22.7 grams; 30.6 grams; 38.0 grams; And 45.8 grams. The method used is linear regression analysis the relationship between the square of the period of T2 oscillation to the load mass M and the data collection for the determination of the modulus value of elasticity of the material is done by ruler oscillation with variation of load mass in the video then analyzed by using tracker software. Furthermore, from T2 data to M is done by linear regression and obtained gradient value which will be used to determine modulus value of ruler elasticity. The value of the aluminum rod elastitis modulus (61.91 ± 5.69) × 109 N / m2 approximates the reference value of 70 × 109 N / m2 with a relative ration of 11.6%.
