Collaborative Problem Solving (CPS) is one of the essential skills of the 21st century. This skill is also must be instilled in students in learning process. CPS can be gauged by using an instrument in the form of inventory. In this study, a web-based Collaborative Problem Solving Inventory (CPSI) was developed with the Learning Development Cycle (LDC) development method. The CPSI developed by the authors is a measurement of innovative Collaborative Problem Solving, emphasizing on measurements before, during and after Collaborative Problem Solving learning activities are carried out. The stages of this research include: (1) Observation, Survey and Needs Analysis; (2) Focus Group Discussion; (3) Preparation of CPSI Design; (4) Development of Web-Based CPSI through LDC Development Model; (5) CPSI validation by experts in developing teaching materials (feasibility) and teachers (practical); and (6) Data Analysis. Based on the results of the study, it was obtained that the CPSI instrument was web-based with indicators for assessing collaboration skills that had been validated by experts and practitioners. The validation results showed that the instrument is feasible to use with minor improvements (validity 3.75 by media experts; validity 3.78 by evaluation experts; and mean 3.65 by practitioners). Follow-up research can be done by testing the instrument in a classroom learning situation, by first making improvements related to the attractiveness of the appearance and website design.
The exploration of macrozoobenthos diversity as a bioindicator parameter in the Bolong river, Magelang has not been widely carried out. This study aims to determine the water quality of the Bolong river based on macrozoobenthos Bioindicator parameters. This research method uses a qualitative descriptive approach. The water quality test is measured based on the level of macrozoobenthos diversity according to the Shannon-Wienner diversity index. The purposive sampling method is used to determine 5 stations for sample collection. The intake of macrozoobenthos is done by using a Surber net and a tray at the bottom of river waters. Moreover, sampling is carried out with three repetitions. The data is analyzed using a diversity index, uniformity index, and dominance index to determine the water quality based on the Bioindicator parameters. Based on the result of the study, the macrozoobenthos diversity index is 1.028. Based on this index, the quality of waters in the Bolong river is considered as moderate pollution.
Distance learning and face-to-face learning at Senior High School of 3 Magelang makes it difficult for students to understand the concept of the system the immune system so that it triggers misconceptions in students. This study aims to analyze students' misconceptions about the material on the immune system at Senior High School of 3 Magelang. The research method is uses qualitative methods to be able to explain more deeply about students' misconceptions. Twenty-five multiple-choice questions in three tiers are given to determine the distribution of students' conceptions. The analysis showed that 64,16% of misconceptions were found in the concept of definition and function of the immune system, followed by the concept of antigens and antibodies with 58.7%, the concept of the mechanism of the immune system with 56.74% and disorders of the immune system with 41.4%. Based on the interviews and questionnaires, the factors that cause misconceptions come from the teacher's teaching methods with less effective, text-books and the lack of student activity, and learning media that have not been varied. So, it can be concluded that students' misconceptions on the material of the immune system are still found with a high level of misconceptions.
This study aims to determine the effectiveness of the Project-Based Learning model conducted via online (e-PjBL) on the concept understanding of evaluation in the biology learning. A quasi-experimental method with a non-equivalent pre-test and post-test group design is chosen in this study. The research is carried out at the Biology Education Study Program of Universitas Tidar in March - June 2021. A total of 63 college students become the sample in this research which are divided into experimental class and control class. The instrument used to collect the data is in the form of a concept understanding test about the evaluation of biology learning. Then, the results of the data are analyzed by quantitative. The results show that there is no difference in the use of online Project-Based Learning models on the concept understanding of evaluation in biology learning. This is indicated by the results of hypothesis test which is 0.184 > 0.05. Meanwhile, the average N-Gain in the experimental class is 0.2083 which belongs to the ineffective category. Next, several factors become obstacles to the online Project-Based Learning that causes this learning model to be ineffective.

Nudibranch are a mollusk which can be found in all zones of ocean. Further, they are distributed widely from subtropical to tropical areas. The Nudibranch is characterized by lack of a shell and usually have a bright shiny color. Nudibranch has a potency to be used in the medical field because they have chemical compound inside their body. These chemical compound are the result of secondary metabolites from symbiosis with zooxanthellae in nudibranch tissues. This research aims to study the structure of epidermal tissue of the Phyllidia coelestis collected from Pasir Putih, Situbondo, East Java Indonesia.
