APPLICATION OF ONLINE LEARNING ON ACID-BASE TITRATION TOPIC TO IMPROVE STUDENTS’ LEARNING INTEREST

Students' interest in learning chemistry, especially in acid-base titration material during the pandemic, makes the learning process ineffective, students tend to be quiet and not interested in learning. The application of learning that can be used during a pandemic is online learning. This study aims to measure students' interest in learning through the application of online learning and to describe student learning activities and student reactions to the application of online learning. The type of research used is quantitative research with quasi-experimental methods and the One Group Posttest-Only Design. This research was conducted at SMA Negeri 1 Banda Aceh with 28 students in class XI MIA 4 taking samples using purposive sampling technique. Collecting data through observation sheets of learning activities and student learning interest questionnaires. The output of the study showed that there were learning activities in the good category with an average value of 90% and 93% observed by the observer. The application of online learning can be used during the current pandemic, seen from the responses of students in the good category with an average score of 76.67. The level of student interest in learning before the application of online learning was 65.71%, after the application of online learning obtained very good results of 77.08%. N-Gain score obtained 32.51 which is included in the medium category. Based on the results of the study, it can be concluded that the application of online learning can increase students' interest in learning.Keywords: Online, interest in Learning, Google Classroom, Acid-Base Titratio

The results of the analysis of the responses obtained an average value of 78, meaning that the 30 students were more dominant in giving a positive response to the questions

CHEMISTRY TEACHER'S PERCEPTION TOWARD SCIENTIFIC LITERACY

Education has a very important role in the development of Indonesian people as a whole. Based on this, it is necessary to develop various sciences in order to improve the quality of learning and intelligence for a nation. Therefore a research has been conducted entitled Perceptions of Chemistry Teachers Against Science Literacy. This study aims to analyze the perceptions of chemistry subject teachers on scientific literacy in several high schools in Aceh. The sample of this research is chemistry subject teachers in Aceh. The approach used in this research is descriptive qualitative. The data collection technique is in the form of an online questionnaire. Based on the results of data analysis and discussion in this study, of the 26 chemistry teachers who filled out a questionnaire, the majority of chemistry teachers had applied scientific literacy to the teaching and learning process after the implementation of the 2013 curriculum. Before the implementation of the 2013 curriculum teachers still often used direct learning. /lecture. Teachers in several areas in Aceh strongly support the application of scientific literacy in chemistry learning. Teachers are eager to take part in the training on scientific literacy that will be held.

ANALYSIS OF SEDIMENTATION TRENDS IN EFFORTS FOR SUSTAINABILITY AT WONOREJO RESERVOIR

Sedimentation is a natural problem that always occurs in water structures, especially dams and reservoirs. Wonorejo Reservoir as a multipurpose reservoir also experienced this. Sedimentation can affect the performance of reservoirs and dams. With the accumulation of sediment, the volume of the reservoir will change from time to time, so it is necessary to estimate the volume of sediment during the useful life of the reservoir and dam, so that they can function optimally. In addition, efforts are also needed to deal with the sedimentation. This study was conducted to estimate the volume of sediment that can occur during the useful life of reservoirs and dams, which is 50 years. Using limited data from previous studies, the study was carried out using the literature study method from other studies that have been carried out in other reservoirs and dams in Indonesia. Based on the estimation results, it is estimated that the volume of sediment in the Wonorejo Reservoir at the end of its age will reach 17.6% of the reservoir capacity volume. So it can be concluded that the reservoir can still work optimally. However, these results are not accurate enough due to the limited data available so that proper sedimentation management efforts are still needed. These countermeasures can be adopted from what has been suggested in other studies for reservoirs and dams in Indonesia
