Changes on the mangrove ecosystem, directly and indirectly, affect the living organisms associated with it, including Molluscs. This study aimed to investigating Molluscs species in mangrove ecosystem of Kendari Bay. It is descriptive research containing facts and natures of mangrove Mollusc species. This study conducted from September to November 2020. Observing and collecting the Mollusc organisms were carried out in four mangrove ecosystems like Bruguiera, Bruguiera/Rhizophora, Rhizophora, and Avicenia. The method used in this research was an exploring technique by collecting and counting the found Mollusks. Indicators of observing the Mollusks included morphological characteristics and environmental parameters. Three important environmental parameters, like salinity, acidity (pH), and temperature, were measured during field works using hand refractometer, pH tester, and thermometer, respectively. This research indicates about 279 individuals of Mollusks found in all zones consisting of 17 species representing two classes, Gastropod (14 species) and Bivalves (3 species). During this research, the Gastropod Mollusks found Telescopium-telescopium, Terebralia palustris, T. sulcata, Cerithideopsilia cingulata, C. alata, Nerita squamulata, Cerithidea quadrata, C. obtusa, Latirus paetelianus, Cerithium kobelti, Chicoreus capucinus, Nassarius stolatus, N. niticusis, Siphonalia varicosus. For the three species of Bivalves are Polymesoda erosa, Anadora granosa, and Sacostrea cucullata. The both species T. sulcata and S. cucullata positively dominated all total found Gastropods and Bivalves namely 21.86% and 3.943%, respectively. The three water quality parameters measured at research stations are still on tolerance limits for the collected molluscs. Keywords: Molluscs, Mangrove Ecosystem, Kendari Bay

Comparison of Project Based Learning and Guided Inquiry in the Development of Understanding of High School Student Concepts. This study aims to compare the understanding of concepts in the Excretion System material between students taught using Project Based Learning (PjBL) and Guided Inquiry (GI). This research is in the form of a quasi experiment with a pretest-posttest non-equivalent control group design. The population of this research is the XI grade students of SMA Negeri 1 Kendari, 2018/2019 Academic Year. The sample of this study was students of Class XI MIPA 1 as an experimental group taught by the PjBL model and students of Class XI MIPA 2, taught by the GI model. Data were analyzed descriptively and inferentially using the SPSS program. The conclusions of this study are (1) There is a significant difference in the understanding of concepts in the excretion system material between students taught with project based learning models and students taught with guided inquiry models as evidenced by differences in the average value of students' posttest and G-gain value in each indicator of concept understanding, (2) Students of the project based learning model class gain significantly higher concept understanding than the group of students in the guided inquiry model class.

Problem based learning was chosen because it has a learner-centered nature and emphasizes independent learning. The purpose of this study is to describe a problem based learning model that can improve student learning achievement and analyze the increase in student understanding of the subject of the human respiratory system after problem based learning is applied. This research was conducted at SMA Negeri 2 Bungku, students of class XI MIA 2, totaling 30 students for the 2021/2022 academic year, having the address Bente, Bungku Tengah District, Morowali Regency, Central Sulawesi Province. The data analysis technique in this study was using descriptive statistics, namely calculating student learning completeness. The test achievement shows that the Teaching Completeness Criteria (TCC) in the first cycle are 70% or 21 students and 30% or 9 students are incomplete with a total of 30 students. Then in the second cycle of the Teaching Completeness Criteria (TCC) in the second cycle there were 90% or 27 students and only 10% or 3 students who did not complete the total number of students as many as 30 students. Cycle III Teaching Completeness Criteria (TCC)) with a maximum score of: 100% of the total 30 students
