Abstract

Local sorghum (Sorghum bicolor) is a cereal crop that the people of Bahari Village, Buton Selatan Regency still cultivate as an interlude crop of corn. Local sorghum (Sorghum bicolor) functions as genetic material and a gene donor to improve the crop’s characters in a plant breeding program. Therefore, it is necessary to take conservation steps to maintain the availability of sorghum germplasm collections. This study aims to characterize local sorghum (Sorghum bicolor) from Bahari Village, Buton Selatan Regency based on morphological characters (qualitative vegetative and generative parameters) and agronomic characters. This study was an explorative study that directly identified the genotypes of local Sorghum bicolor cultivated in the field. This study reveals six genotypes of local Sorghum bicolor; they are Labanda, Lapandewa, Lagadi, Wapinauri, Mbae, and Madea. The differences in sorghum genotypes can be more clearly identified in the generative phases, namely the symmetrical and pyramidal panicle shapes; the panicle density can be grouped into loose, slightly compact, and compact; husk colors vary from black, orange, grey, yellow, white, to red; the husk traits are categorized into short, slightly long, and very long; and the seeds are categorized round and round flat and white and brown. Meanwhile, the agronomic characters indicate that sorghum genotypes have long panicles; the weight of 100 seeds vary in categories from very low, low, to moderate; and one sorghum genotype (genotype Lagadi) has the fastest flowering and harvest ages than the other genotypes.

Abstract

The Covid-19 pandemic that has hit the entire world has caused changes in learning patterns from classroom to virtual classroom activities, and this has caused biology teachers to experience problems when teaching material through direct practicum activities. There is a need for solutions that can facilitate practicum activities by developing a virtual laboratory application. This research develops a Virtual Biology Laboratory (VLab-Bio) application based on Biology, Technology, Engineering, and Mathematics (BTEM) that is feasible and practical to facilitate virtual lab work on the concept of bacteria. The application product produced from this research is expected to help students facilitate practicum activities and improve critical thinking skills on the concept of bacteria. The application produced from this research is expected to help students improve their critical-thinking skills and lab work on bacterial material. Akker development model was used with four stages of development: preliminary research, prototyping, summative evaluation, and systematic reflection and documentation. The research instrument consisted of tests of critical-thinking skills and non-tests in the form of observations of the learning process and student response questionnaires. The research data were analyzed qualitatively and quantitatively with the paired t-test. The results showed that the BTEM-based virtual laboratory developed was classified as valid and effective in improving students’ critical-thinking skills with 78% effectiveness. Based on this research, it can be recommended that using a BTEM-based virtual laboratory can be used as a supplement in facilitating bacterial concept practicum activities. For further application development, it is hoped that the application can provide flexibility for students to develop their own practicum procedures in applications.

Abstract

Not a few students who have difficulty interpreting the material being studied in terms of life encourage the need for a paradigm shift in science learning, which is directed at lifelong learning. In this paper, an entrepreneurship-oriented 5E (Engagement, Explain, Exploration, Elaboration, and Evaluation) inquiry learning program is developed, which is also often called 5E+e. This research investigates the improvement of lifelong learning for the prospective teachers during the 5E+e inquiry in the plant diversity course. The quasi-experimental method with a one-group pretest-postest design was used. The research subjects were taken by purposive sampling, namely the fifth-semester students of the Biology Education Study Program at one of the Teachers Institution in Central Java with 31 participants. Data were gathered using a questionnaire filled out by students before (pre) and after (post) the treatment of the 5E+e inquiry learning and observation. The data analysis was carried out in both quantitative and qualitative-descriptive manners to make a comprehensive conclusion. The results revealed that the average lifelong learning score of prospective teachers compiled with rubrics had increased between before (2.68) and after being given the program (3.26) with a maximum score of 4.00. Thus, it can be concluded that the entrepreneurship-oriented inquiry learning program applied to the plant diversity course can increase the lifelong learning of prospective teachers.

Abstract

A mental model was students’ internal representation when they learned a concept. The conceptual model is a description of natural phenomena following the views of scientists. Most high school students have an idea of classical physics on understanding the concept of the photoelectric effects. Understanding the photoelectric effect is key to comprehend the fundamentals of quantum physics. The photoelectric effects can explain the quantization of energy that is explainable by a classical physics theory. This research's learning modeling aims to identify and investigate the profile of Class XII high school students’ mental models by regarding the concept of the photoelectric effects. This research employed descriptive methods. The research sample was selected purposively. This research used a diagnostic test for the pretest to determine the initial knowledge about the photoelectric effect of 30 students (12 male students and 18 female students) from the XII MIPA class at SMA Negeri 1 Pekalongan. The pretest questions consisted of 4 description questions. The pretest results were then analyzed and used to determine six students for an interview process, two students with high results, two students with medium results, and two students with low results. The interview results reveal that the students usually implement classical physics knowledge when developing mental models of the photoelectric effects.
