Abstract

This study aims to describe students’ perceptions of the implementation of the Project -Based Learning (PjBL) model combined with the use of teaching aids in learning the human respiratory system in Grade XI at SMAN 1 Bunobogu. The study employed a descriptive qualitative approach. The research subjects consisted of three students purposively selected based on different levels of ability. Data were collected through participatory observation, in-depth interviews, supporting questionnaires using a Likert scale, and documentation. Data validity was ensured through source and method triangulation, while data analysis followed the Miles and Huberman model. The results indicate positive perceptions across all three aspects. The cognitive aspect showed a supporting questionnaire score of 3.56 (good category), and the teaching aids effectively transformed abstract concepts into more concrete representations. The affective aspect, with a score of 3.58, reflected increased learning interest and motivation. The psychomotor aspect, with a score of 3.53, contributed to the development of practical skills, creativity, and teamwork.

Abstract

This study aims to determine the abundance of Scylla sp. crabs in the mangrove forest area of ​​Lalombi Village, South Banawa District, Donggala Regency. The type of research used is descriptive quantitative. The technique for determining the location for sampling is using the purposive sampling method. Sampling of Scylla sp. crabs was carried out directly by hand collection method at low tide. The population and samples in this study were all types of Scylla sp. crabs found in the research location. Data analysis was carried out by calculating the abundance index, to determine the level of abundance of the crab species found. The Scylla sp. crab samples obtained amounted to 4 species, namely Scylla tranquebarica with an abundance index of 46%, Scylla paramamosain with an abundance index of 36%, Scylla olivacea with an abundance index of 43%, and Scylla serrata crabs are the most abundant crab species with an abundance index of 49%. The abundance index value of Scylla sp. crabs obtained in the mangrove forest area of ​​Lalombi Village, South Banawa District, Donggala Regency shows a moderate level of abundance.

Abstract

This study aims to improve students' learning outcomes in Biology for Grade X students of SMK Manbaul Hikmah through the implementation of the Problem Based Learning (PBL) model. The research employed a descriptive qualitative approach using a Classroom Action Research (CAR) design conducted in two cycles. Each cycle consisted of planning, action implementation, observation, and reflection stages. Data were collected through observation sheets of teacher and student activities as well as learning outcome tests administered at the end of each cycle. The results indicate that the application of the PBL model significantly improved students' learning outcomes. In Cycle I, classical learning mastery reached 85%, while in Cycle II it increased to 92%. The 7% improvement in classical mastery demonstrates that the PBL model is effective in encouraging students to think critically, collaborate, and solve problems related to contextual learning materials. In addition, students' activity and engagement during the learning process showed continuous improvement in each cycle. Therefore, the Problem Based Learning model can be considered an effective alternative for improving Biology learning outcomes of Grade X students at SMK Manbaul Hikmah.

Abstract

This study aimed to analyze the community structure of fiddler crabs (Uca) in the mangrove ecosystem of Lalombi Village, South Banawa District, Donggala Regency, and to utilize the research findings as instructional media in the form of a flipbook. This ecological study employed a quantitative descriptive approach based on community structure analysis, with samples collected using purposive sampling. The parameters analyzed included species composition, density, the Shannon–Wiener diversity index, the Simpson dominance index, and the evenness index, along with environmental variables such as temperature, salinity, pH, and substrate type. The results showed that the fiddler crab community in the mangrove ecosystem of Lalombi Village consisted of five species, namely Uca annulipes, Uca lactea, Uca forcipata, Uca tetragonon, and Uca dussumieri. Abundance varied across sampling stations, and the overall diversity level was classified as low to moderate. The occurrence frequency of these five fiddler crab species was very low. The recorded densities were 6 ind/m² for Uca annulipes, 3 ind/m² for Uca lactea, 5 ind/m² for Uca forcipata, 7 ind/m² for Uca tetragonon, and 3 ind/m² for Uca dussumieri, with a low dominance index. The environmental physicochemical conditions recorded for fiddler crab habitat were a temperature of 30°C, water pH of 8.25, salinity of 31, and a muddy substrate type. Overall, the fiddler crab community structure in the mangrove ecosystem of Lalombi Village was relatively stable, characterized by low to moderate diversity, low dominance, and a clumped distribution pattern influenced by substrate conditions and mangrove density.
