Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model Community of Inquiry (CoI) menggunakan aplikasi LINE terhadap penguasaan konsep dan kemampuan menyelesaikan masalah siswa SMA pada materi sistemekskresipadaginjal. Dalam penelitian ini, digunakan non-equivalent control group design. Partisipan dalam penelitian ialah siswa kelas XI MIPA SMA, terdiri dari 36 siswa kelas eksperimen dan 34 siswa kelas kontrol. Instrumen yang digunakan terdiri dari tes penguasaan konsep dalam bentuk pilihan ganda dan essay, tes kemampuan menyelesaikan masalah dalam bentuk essay, angket respon siswa terhadap model CoI, lembar observasi keterlaksanaan sintaks, dan wawancara. Terdapat empat indikator kemampuan menyelesaikan masalah yang diukur, yaitu mengidentifikasi masalah, menganalisis masalah, merumuskan alternatif solusi, dan menentukan satu solusi terbaik.Berdasarkan temuan yang didapat, model CoI berpengaruh terhadap penguasaan konsep siswa pada materi ekskresi ginjal pada level C1 sampai C5, dan juga berpengaruh terhadap kemampuan siswa dalam menyelesaikan masalah, khususnya pada indikator merumuskan beberapa alternatif solusi. Data respon siswa menunjukkan bahwa siswa setuju dengan penerapan model pembelajaran CoI, dengan respon positif terbanyak ada pada indikator sintaks triggering event.

Abstract

The research was motivated by 21st-century developments which made major changes and covered all aspects. Thereby, it was important to master 21st-century skills to be able to deal with these changes. Furthermore, low graphic skills at Senior High School (SHS) level must be considered so they could understand the visual information currently available. Stream Ecology Graphing Unit (SEGU) was a learning strategy to facilitate students to “mind-on” in understanding graph concept. The purpose of the research was to analyze the effect of applying SEGU towards the graphic and collaborating skills of SHS on reproductive material. This research used a Quasi-experimental with Non-Equivalent control group design. The samples were two classes of XI MIPA in an SHS in Bandung which was taken using Purposive sampling. The instruments used were pre-test, post-test, rubrics of measuring collaborating skill, and questionnaires for students’ response towards SEGU. The result showed significant differences between the experimental and control groups in graphic and collaborating and showed intended meaning towards the implementation of SEGU. Most of the students gave a positive response towards SEGU.

Abstract

This study aims to determine the profile of the ability of senior high school biology teachers in designing and testing local material-based bacteria and fungi cultivating practices during the Covid-19 pandemic. The method used in this study is a descriptive method with a qualitative approach. The participants in this study were 33 senior high school biology teachers at West Java province, Bandung. The data collection technique used the lesson plan assessment rubric, student worksheet, and practicum trial reports, besides that used both teacher profile and activities and obstacles questionnaires during the training. The research data analysis technique used data triangulation, data presentation, and conclusions. The data validity test includes data testing, data reliability testing, external validity/generalization. The results show that the profile of Senior High School biology teachers regarding teaching experience, as many as 63% of teachers had more than 10 years of teaching experience. The achievement of eligibility obtained a score of 85% (good category). These criteria include content, presentation, language, graphics, ease of usage, suitability of appearance, and usability of student worksheet features. The results of the questionnaire show that 91% of participants thought that the design and practical trial activities are very useful, 83% of participants thought that the material that had been delivered could be applied in schools. So that biology teachers can innovate further by using local materials to carry out practicum activities.

Abstract

The teacher's difficulty in assessing student performance when students work in groups outside class hours causes the need for peer assessment to be carried out. Project-based learning is a suitable space for applying peer assessment because it consists of tasks that students in groups usually do. This study describes the application of peer assessment in product performance assessment in project-based learning on ecosystem materials. This study uses a descriptive method involving 34 high school students in class X. Peer assessment is done by students assessing the products made by their group of friends. The application of peer assessment in this study was carried out three times, namely at the stage of product design, product assessment, and product presentation. An analysis of the performance assessment results through peer assessment is conducted, and the similarity of the results of the peer assessment to the teacher's assessment at each stage. The study results showed that there was a tendency for an increasing student's ability to judge. This result is evidenced by the increasing similarity of teacher assessments and peer assessments at each stage. The similarity between peer assessment and teacher assessment at the product design stage is 58.8%; product assessment stage by 64.7%; and the product presentation stage of 70.6%. The student response questionnaire identified that the application of peer assessment provided many benefits to students. Based on the results of this study, peer assessment can be an alternative in overcoming teachers' difficulties in assessing student performance when project work is carried out outside class hours through project-based learning.

Abstract

This study aims to determine the effect of the Argument-Driven Inquiry (ADI) learning model application on the concepts mastery and argumentation skills of high school students on reproductive system material. The research method used quasi-experimental and non-equivalent control group design. The sample of this research were second-grade high school MIPA students in one of the public high schools in Bandung, which consists of 30 students in the experimental class and 33 students in the control class. The sample was taken by using the purposive sampling technique. The instruments used consisted of a concept mastery test in the form of multiple choices, an argumentation ability test in the form of an essay, and questionnaire of students’ responses to the ADI model. The results showed that the application of the ADI learning model significantly affected the students' concepts mastery on reproductive system material in the experimental class compared to the control class, especially in the cognitive aspects of C3 (applying). The results also show that the application of the ADI learning model significantly affects the ability of argumentation, especially on the warrant component. Student response data shows that students respond very well to the application of the ADI learning model. Therefore, the ADI learning model is recommended for biology teachers to improve students’ concepts mastery mastery and argumentation skills in other biological materials.

Abstract

Antifungal activity of the ethanol extract of bay-leaf (Syzygium  polyanthum (Wight) Walp.) against growth of the fungus Candida albicans in vitro has been conducted. Leaves of S. polyanthum has been known to have potential as antifungal for skin fungal pathogen. This study aims to determine antifungal activity of the ethanol extract of S. polyanthum leaves against growth of C. albicans.  Activity test was done by disc-diffusion  method and macro-dilution. This study used concentrations of ethanol leaf extract of S. polyanthum of 0.5%, 1%, 1.5%, 2%, and 2.5% (w/v). Negative control using 1% DMSO and positive controls using ketoconazole 30 mg/mL. The results shows that ethanol extract of leaves of S. polyanthum have activity as an antifungal. Ethanol extract of leaves of S. polyanthum based on the results of GCMS analysis of compounds containing chemical compounds such as terpenoids and fatty acids. Ethanol extract of leaves of S. polyanthum showed the highest inhibition zone diameter at a concentration of 1% (w/v) of 9.32 ± 0.21 mm. Value of Minimum inhibitory Concentration (MIC) for ethanol leaf extract of S. polyanthum present in a concentration of 0.5% (w/v) and the value of Minimum Fungicidal Concentration (MFC) present in a concentration of 1% (w/v).
