This research was aimed to produce a valid, practice, and effective student worksheet based on guided inquiry for transport membrane topic to train integrated science process skill. The development was reffered to 4D (define, design, develop, and disseminate) method without disseminate. The developed student worksheet was implemented to twenty 11th grade students of Senior High School Muhammadiyah 1 Taman. The observed method were validity method, observation of student worksheet implementation, test method, and questionaire method. Data was analyzed with qualitative and quantitative descriptive. The result of this research showed that the developed student worksheet was proved completely valid with validation score 3.87. The student worksheet practicality determined from the student worksheet implementation that gained the average of practicality score 87.67% with very practice category. The developed student worksheet was stated completely effective which determined from the achievement result of science process skill and student positive response. The achievement result of science process skill gained score 80.6% with an N-gain 0.60. Besides, the student positive response had score percentage 96%. Based on the result, it can be concluded that the student worksheet were valid, practice, effective and worthy to be used in the learning proccess.

The aim of this study was to find out whether or not there was a significant difference of students’ speaking anxiety across gender. This study used survey method. The population was the second grade students of SMAN 2 Kendari in academic years 2017/2018. This study involved 184 students (92 males and 92 females) who were taken from proportionated stratified by random sampling. An instrument employed in this study was a questionnaire of Foreign Language Classroom Anxiety Scale (FLCAS). The data were analyzed by using descriptive and inferential statistic. The result of descriptive analysis showed that students’ speaking anxiety was affected by three factors namely communication apprehension, test anxiety, and fear of negative evaluation where each factor had a neutral position and majority students had a moderately anxious level on speaking anxiety. The result of the t-test showed that tobserved was -2.007 and ttable was 1.973. It means that ttable was lower than the tobserved. Thus, there was a significant difference of speaking anxiety between male and female students where females were more anxious then male.

Paper waste is an organic residual that has not been widely utilized and its existence around us. The high cellulose content in paper waste allows it to be used as a media for cultivating white oyster mushrooms. This aims to compare the speed of mycelium propagation from different concentration of paper in each growing medium. The study used a Completely Randomized Design (CRD) with six treatments and five repeattation. The treatment used is the difference in the composition of 0% paper waste media (control); 20% of paper waste; 40% of paper waste; 60% of paper waste; 80% of paper waste; and 100% of waste paper. The data were obtained from six time observations in the form of mycelium propagation (cm)and tested with anava. The results were not significant at 1,65 using correcttion factor 2,53. Mycelium propagation speed was influenced by environmental factors such as temperature, light intensity, humidity, and air circulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
