Abstract

This research aims to know community structure of crabs present in mangrove at Pinotu village, Toribulu subdistrict, Parigi Moutong regency and to developed its resultant for biology learning media being a pocket boo. The research was descriptivelycarried out at the village and was improved to design 4D. Sampling was undertaken by observing crabs found in each of the determinate stations in which those was then divided into quadrant transect and retrieval time consisting of 11.30 – 12.30; 17.00 – 18.00; 23.30 – 24.30 periods. The resultant observation was eventually to be a pocket book for biology learning media. Results of the research showed that 6 species of crabs were found in the area including Uca annulipes, Uca rosea, Uca paradussumieri, Scylla serrata, Epixanthus dentatus, and Sarmatum germaini. Total of the observed crabd was 297 individuals. Absolute density value and retrieval times were mostly found in station II during 18.00 – 19.00 periods. Sarmatium germaini was a species of crabs possessing the highest of the relative density value (55,56%). Moreover, diversity index per station ranged 0.7305 – 0.7491 that means it was less then 1.0 indicating a low diversity. For dominancy index, it ranged 0.678 – 0.776. the highest dominancy was observed in station III valued 0.0776 suggesting that a richness of species of crabs was a quite low. Distribution patterns of species present in station I, III, and III were 0.394, 0.304, and 0.016, respectively, recommending that those were uniform distribution patterns. These seems that the habitats, physical factors, retrieval times strongly affected on crab community present in the mangrove forest. In addition, data analysis showed that the community structure of crabs in mangrove forest at Pinotu village was categorized as a low diversity that it was highly resulted in an ecological pressure. The developed pocket book has been validated by content, media, and design experts providng the following value: 91.4%, 9.71%, 77.33%. it has also been tried out to small group and larged group giving the values; 87.2%  and 84.4% respectively. Accordingly, the pocket book can be appropriately used as biology learning media.

Abstract

The community in RT.05/RW.13, Tondo Village, Mantikulore District, Palu City, shows a low level of awareness in maintaining environmental cleanliness, particularly in managing household waste. This condition contributes to the spread of pathogenic bacteria through cockroach vectors (Periplaneta americana), which can cause various diseases. This community service program aimed to enhance public health literacy regarding environmental cleanliness, the resistance of endogenous bacteria carried by cockroaches, and to establish the sustainability of environmental health literacy. The program applied the Participatory Action Research (PAR) method, consisting of four stages: to know, to plan, to act, and to change. The program involved 24 residents of RT.05/RW.13 and was conducted on July 26-27 and August 3-5, 2024. Results indicated an improvement in public understanding, with questionnaire results showing an 84% score categorized as good. Additionally, an educational poster about the dangers of cockroaches as disease vectors and their bacterial resistance was developed and installed in the community area. This increase in health literacy is expected to motivate behavioral changes among residents in maintaining environmental cleanliness, ultimately supporting the creation of a healthier environment

Abstract

This study aims to describe the obstacles faced by biology teachers at the senior high school (SMA) level in South Palu District in implementing the Independent Curriculum. The method used was descriptive qualitative, with biology teachers from two schools in South Palu District as subjects. The research instruments were interview sheets and questionnaires. The questionnaires were analyzed using an average score calculation to determine the category of obstacles, while the interview data were analyzed qualitatively through data reduction, data presentation, and conclusion drawing. The results of the questionnaire analysis showed that teacher obstacles ranged from low to very low. Among the three aspects, implementation had a relatively greater level of obstacles than planning and assessment, but remained in the low category, while planning and assessment were both in the very low category. Interviews supported these findings, namely that teachers still relied on training modules and experienced difficulties in adapting assessments to student characteristics, as well as facing limitations in facilities and technology. In general, it can be concluded that the obstacles faced by Biology teachers in implementing the Independent Curriculum in South Palu District are in the low and very low categories, but mentoring, competency strengthening, and infrastructure support are still needed so that curriculum implementation can run optimally.

Abstract

This study aims to determine the effect of the Project Based Learning learning model using Mind Mapping on student learning outcomes in class VIII of SMP Negeri 5 Bolano Lambunu. This research method is a quasi-experiment (Quasi Experiment) with a Non-equivalent (Pretest and Posttest) Control Group Design. The sample of this study was 34 students, consisting of 17 students in the experimental class who used the Project Based Learning learning model using Mind Mapping and 17 students in the control class who used the conventional learning model. Data collection was carried out by conducting observations, interviews, and tests. Data analysis used prerequisite tests, namely, normality tests and homogeneity tests and hypothesis testing using the Independent Sample t-test and N-gain tests. The results of the study showed that (1) there was an effect of using the Project Based Learning learning model using Mapping on student learning outcomes. This is evidenced by a significant increase in student learning outcomes in the experimental class, with an average posttest score reaching 73.23, while the control class was only 64.70. The t-test shows a p value < 0.05, which means that the implementation of the Project Based Learning model using Mapping has a positive effect on student learning outcomes. (2) N-gain analysis shows that the experimental class has an average N-gain score of 0.65 (65%), which is included in the fairly effective category, while the control class is only 0.51 (51%), which indicates a less effective category. Thus, it can be concluded that the Project Based Learning learning model using Mind Mapping is effective and can affect student learning outcomes in the science subject of class VIII-B SMP Negeri 5 Bolano Lambunu.
