Bioecology of Coconut crab (Birgus latro L.) On Kaledupa Island, the objective of the research is to know the Biological characteristics (morphometric measurements in the length and width of the carapax, cephlathorax added rostrum (Cp + r) and body weight) and to know the Ecological characteristic (population size) Coconut crab which is on the island of Kaledupa. Sampling technique used the CMRR (Capture-Mark-ReleaseRecapture) method. Data analysis techniques used: (1) Coconut crab morphometry. Data were analyzed descriptively by calculating the average length and width of the carapax, cephalothorax + rostrum length and body weight, (2) Data on sex ratio and population estimation were analyzed quantitatively. Based on the result of the analysis, the highest morphometric measurements are the length of the carapax with an average of 6.37 cm, the width of the carapax 6.03 cm, the length of the cephalothorax + rostrum 10.06 cm, which is located at the location of Station I (Hoga island, Furake sub-village). This is because of this station has unspoiled environmental conditions and there are burrows or caves where the Coconut crab is hiding, where the station belongs to the Wakatobi National Park which is a protected area, and has coconut and other shrub vegetation. These are a food source of Coconut crab s, so this area is ideal for the survival of Coconut crab. The lowest morphometry measurements obtained by carapax length with a mean of 5.62 cm, carapax width of 5.49 cm, length of cephalothorax + rostrum of 9.044 cm, which is found at the location of Station II (Sombano village). This is thought to be the condition of habitats that have been converted into other uses such as the opening of plantation land, so many of the Coconut crab hide outs are damaged. The comparison of male and female sex ratio is 13 Male: 7 Female.

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.

The quality of science learning in the science field is still low. This study aims to determine the effect of the scientific approach on students' communication skills and understanding of concepts related to pollution materials. This type of research is a quasi-experimental design with a pretest-posttest design with only control groups. The study population consisted of all seventh-grade students at the SMP Negeri 9 Buton enrolled in the even-numbered semester of the 2021/2022 academic year. The study sample consisted of 45 students. The sampling technique was simple random sampling. A multiple-choice test served as an instrument for examining the communication skills and understanding of the students' concepts. Research data is analyzed descriptively and inferentially. The results showed that a scientific approach had a positive and significant impact on students' communication skills and understanding of pollution concepts. Key words: Scientific approach, Communication skills, Understanding of concept Abstrak Mutu pembelajaran IPA pada bidang sains masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan saintifik terhadap keterampilan komunikasi dan pemahaman konsep siswa pada materi pencemaran lingkungan. Jenis penelitian ini adalah quasi eksperimen dengan desain pretes-postest only control group design. Populasi penelitian adalah seluruh siswa kelas VII SMP Negeri 9 Buton yang terdaftar pada semester genap tahun ajaran 2021/2022. Sampel penelitian berjumlah 45 siswa. Teknik pengambilan sampel adalah simple random sampling. Instrument penelitian keterampilan komunikasi dan pemahaman konsep siswa yang digunakan berupa tes dalam bentuk pilihan ganda. Data hasil penelitian diolah secara deskriptif dan inferensial. Hasil penelitian menunjukan bahwa terdapat pendekatan saintifik berpengaruh positif dan signifikan terhadap keterampilan komunikasi dan pemahaman konsep siswa materi pencemaran lingkungan. Kata kunci: Pendekatan saintifik, Keterampilan komunikasi, Pemahaman konsep
