The village of Lamundre is an area overgrown with a mangrove ecosystem of 4 hectares and is well developed on the coast. The area can be well overgrown with mangroves because of environmental conditions and other supporting factors such as muddy substrate, muddy sand in tidal transition areas, salty, brackish water and the presence of currents/waves that are classified as mangrove growing conditions. This study aims to determine the types of mangrove plants and environmental parameters on the abundance of mangrove species on the coast of the Rainbow Bridge, Lamundre Village, Watubangga District, and Kolaka Regency. This type of research is descriptive and qualitative by using mangrove samples on the roots, stems, leaves, flowers and fruit. The method used is Line Transect, which uses plots that are aligned on the main line (Basseline) that has been determined in the research area along 280m, the total number of plots is 10, with each plot of 10m x 10m. Based on the study's results on the identification of mangroves in the Pantai Pelangi Beach, Lamundre Village, Watubangga District, and Kolaka Regency, it shows that mangroves belong to 2 families and 7 species. The mangroves are from the Rhizophoraceae family namely Rhizophora mucronata species, Rhizophora apiculata, Rhizophora stylosa, Ceriops decandra, Bruguira cyndrica, Bruguira ghymnorryza and the Soneratiaceae family namely Soneratia caseolaris.

The current state of the Covid-19 pandemic has had an impact on various ongoing activities, including learning activities. Currently, the government provides a policy to organize learning from home, known as Learning From Home (BDR). Learning From Home in its implementation requires the support of mobile devices. It is a challenge for both teachers and students to master technology in learning in these conditions. In addition, teachers must also be able to carry out the teaching and learning process or provide assessments/evaluations to students face-to-face (done online). The research objective is to determine the use of alternative assessment-based portfolios in biology learning. The authors want to introduce web-based portfolios as alternative assessments in biology learning in this study. Alternative assessments can support students to understand biology lessons with the task of making lab reports, making herbariums, drawing, writing widespread scientific reports, etc. These are collected in the form of website links. The research method used is a literature study that the author has carried out. The results obtained are using a web-based portfolio as an alternative assessment in biology learning, which is still not widely applied even though this assessment is very efficient to apply in biology learning during the Covid-19 pandemic. This research concludes that every lesson that has been carried out certainly needs to be assessed on student learning outcomes in following each lesson that has been followed. In this case, an alternative web-based portfolio assessment is one of the solutions to evaluate the performance and work of students so that all activities carried out can be rewarded with value.

The seventh grade science teacher at MTsN 3 Kota Pariaman has problems in developing an instrument for assessing higher order thinking skills. In the 2013 curriculum, teachers are required to be able to provide questions in the C4-C6 domain, namely High Order Thinking Skills (HOTS). This study aim to produce a valid and practical assessment instrument for higher order thinking skills on environmental pollution material at the C4-C6 cognitive level. The background of this research is that the questions made by the teacher are still at the C1-C3 level and there are still obstacles for teachers in developing higher order thinking skills assessment instruments, while inthe 2013 curriculum teachers are required to be able to provide questions in the C4-C6 domain. This type of research is research development (Research and Development) which is a research method used to produce certain products. This type of research uses 3 stages of the 4-D model, namely the define, design and develop stages.Based on the research conducted, a very valid assessment instrument of 3,32 was produced by thevalidator, the empirical validity there were 30 valid questions and 10 invalid questions, the reliability in this study was 0,77 with the category of reliability, 94,79% teacher practicality and practicality. students amounted to 80,80%, the difficulty level of the questions was between 0,31 to 0,70 with moderate criteria and the question difference had sufficient criteria. This research can be used as a reference for other researchers related to the development of higher order thinking skills assessment instruments.Keywords : High Order Thinking Skills, Validity

The learning process in class still uses a lot of methods conventional and is less creative in conveying material, namely the model has not been applied one of the innovative learning models is the STAD learning model. The research purpose is to determine the effect of the STAD cooperative learning model on student learning outcomes of SMP Negeri 2 Wundulako. This type of research is quasi-experimental. This research was quantitative. The population in this research were all students of class VIII SMP Negeri 2 Wundulako, amounting to 56 people. The sampling of this research used the purposive sampling technique with certain considerations that each class has the same initial cognitive ability. As the experimental unit, there were two research classes, namely one experimental class and one control class, each of which was 28 people. The data was collected using non-test techniques, observation sheets for student learning activities, and tests in the form of multiple-choice pretest-posttest questions. Then analyzed by descriptive statistic analysis and inferential static analysis. The results of the research inferentially on student learning outcomes using the Independent sample t-test at the significance level = 0.05, obtained t count 8.799 and t table 1.674 because t count ≥ t table, indicating that H0 was rejected and H1 was accepted. It could be concluded that the application of the role-playing model to the digestive system material affected the learning outcomes of class VIII students of SMP Negeri 2 Wundulako.

Learning media is one component of learning. The accuracy of the selection of media and learning models that will be applied is one of the factors in the success of effective learning. This study aims to obtain the results of the analysis of student needs for android-based learning media in biology subjects. This student needs analysis is focused on SMPN 16 Poleang Tengah students. The selected method in data collection is a quantitative method using the purposive sampling technique. The sample used to obtain the data is class VIII student respondents and consists of 22 respondents. Data were collected by filling out a questionnaire the form of a questionnaire. The results of this questionnaire data are then processed and made in the form of percentages and tables. Analysis of student needs for Android-based learning media shows that the use of Android-based learning media in the learning process is very much needed, and students feel interested in using Android as a learning medium. This can be seen based on the percentage of statements agreeing to manufacture android-based learning media in biology subjects, namely the percentage of 90.1% agreeing. The analysis of student needs will be used to design android-based learning media for biology subjects in class VIII of SMP Negeri 16 Poleang Tengah. Keywords: Learning media, Android,
