The duckweed plant group belongs to the botanical family Araceae and has the potential as a food source. It is difficult to classify and the plants were originally grouped as the Lemnaceae family. However, current molecular taxonomy studies revealed the integration of Lemnaceae into the Araceae family, thus becoming the Lemnoideae subfamily. It is necessary to strengthen the position of Lemnoideae in Araceae using molecular marker psbA from chloroplast DNA This study aimed to determine the role of the psbA chloroplast DNA marker in regulating the position of Lemnoideae. A total of 41 sequences of the psbA gene taken from the species from seven subfamilies in Araceae and one outgroup were collected from the NCBI GenBank and then arranged in FASTA format. Sequence data was then aligned by ClustalX, and phylogenetic trees were reconstructed using PAUP and MEGA. From the resulting phylogenetic trees, it can be conferred that the Lemnoideae subfamily does not form a monophyletic group. Thereby, this in silico study using psbA markers concludes the position ofthe Lemnoideae subfamily in the family Araceae and we recommend not separating the plant group from the family Araceae.

Metacognition and the self-system are critical components influencing an individual's learning success. The ability to reflect on and regulate one’s learning processes must be accurately identified and assessed to support instructional planning that enhances these skills. This descriptive study aims to examine the metacognitive abilities and self-system of fifth-semester students enrolled in the Biology Education Study Program at the Islamic University of Riau. Utilizing a survey method, data were collected from a sample of 30 students, consisting of 6 males and 24 females. The instrument, a questionnaire based on Marzano’s Taxonomy and comprising three indicators per variable, was validated through expert review. Data were analyzed using percentage-based categorization and further examined through a Pearson product-moment correlation test via SPSS 22. Results indicated that all metacognitive indicators fell into the high category, with clarity monitoring achieving the highest score (80.27%) and process monitoring the lowest (77.87%). For the self-system, examining importance and emotional response were categorized as high, while efficacy was rated moderate. A significant positive correlation was found between metacognition and the self-system (r = 0.536), with the regression equation Y = 36.662 + 0.478X. These findings suggest that students exhibit high levels of both metacognitive and self-system abilities, which are significantly interrelated.Keywords: biology education, metacognitive, self-system, undergraduate

Problem-based learning (PBL) is an effective educational approach that promotes critical thinking, collaboration, and creativity. The study aimed to review an implementation of PBL in engineering course in Malaysia. PBL has been shown to be effective in engaging students in the learning process by presenting them with complex, open-ended problems that require critical thinking and creativity to solve. Through this process, students develop their critical thinking skills, including their ability to analyze information, evaluate arguments, and make sound judgments. PBL also helps students to develop their problem-solving skills, which are essential in the real world. Despite its benefits, implementing PBL in the classroom can also have some challenges and limitations. It can be time-consuming, difficult to assess, challenging to implement in large classes, and may not be suitable for all students. Thus, careful planning and preparation are required before implementing PBL in a university setting. In an engineering course, PBL provides students with opportunities to develop their critical thinking and problem-solving skills, as well as to enhance their collaboration and communication abilities. It also allows students to see the relevance of the knowledge and skills they are learning and to take ownership of their learning. Therefore, implementing PBL in a university requires identifying appropriate learning objectives and designing a problem or scenario that aligns with those objectives. The problem or scenario should be complex and open-ended, requiring students to draw on knowledge and skills from multiple subject areas. The implementation of PBL should also involve ongoing evaluation and refinement to ensure its effectiveness.

Teaching environmental chemistry today involves both conventional and digital learning modes. Traditional approaches such as lectures, problem-solving, and laboratory exercises, offer content that is more or less structured with direct interaction, but not active engagement, interactivity, and enough resources are often found wanting. To better learn the subject, blended learning has been introduced, including some important digital tools like online facilities, simulations, and virtual labs. These ensure access and increase participation but the major con that students show low motivation because of the unequal access to the tools, the challenge that teachers face using the new tools, low student motivation, and problems in assessment. Its use has grown, but the effectiveness of blended learning, especially in stoichiometry and mass balance, which are considered to be rather complex, is not well documented. This review aimed to answer how traditional, digital, and blended learning approaches work in environmental chemistry education and what the benefits and challenges of each are. While traditional methods are more inclined to encourage the interaction of the instructor, which already appears to be passive and sometimes disconnected from the real situation outside the classroom, the blended learning method will put forward greater interactivity and personalization, though much will now depend on the individual student and the access to technology. A balanced approach will be evidenced by blended learning, with the strong points imbibed from both the modes, but, however, much intelligence is required to apply it to steer clear of further weaknesses. For improvement in the teaching of Environmental Chemistry, it is essential to invest in the digital infrastructure, faculty training, strategies of student engagement, and innovative models of assessment. If applied strategically, then blended learning can bridge effectively between theory and practice, making the teaching of Environmental Chemistry more engaging, inclusive, and outcome-based.

The purpose of this research is to provide information about the challenges of citizen science project learning in Indonesia, so that its implementation is maximized. The research method used is descriptive qualitative. Data collection was conducted through interviews, observations, and literature review. The researcher used data triangulation which aims to increase the researcher's understanding of the data and facts. This local community engagement learning provides enormous benefits in school learning. The advantages of this learning are the involvement of experts and non-experts in the learning process, students learn from real objects, produce various products, and increase knowledge and skills. In addition, the disadvantages of this learning require additional time in the learning process. Challenges in citizen science project learning include cohesiveness or closeness of learners, interpersonal communication, use of information technology, and time. Thus, citizen science project learning is one of the current learning innovations that can be applied by teachers in schools.

HIDAYAT, TOPIK; YUKAWA, TOMOHISA; ITO, MOTOMI. 2006. Evolutionary analysis of pollinaria morphology of subtribe Aeridinae (Orchidaceae). Reinwardtia 12(3): 223–235.–– Pollinarium is one of the distinct synapomorphies of Orchidaceae. With using characters derived from the pollinarium, phylogenetic relationships among genera of subtribe Aeridinae was examined. Cladistic analysis showed that (1) Subtribe Aeridinae is monophyletic group. (2) Five of six groups constructed in the analysis are consistent with the groups recognized in previous molecular phylogenetic analyses.(3)The genera Cleisostoma and Phalaenopsis are non-monophyletic group.(4) Pollinarium morphology endorses monophyly Trichoglottis and Phalaenopsis alliances. (5) Although transformation of the stipe and viscidium shapes in the subtribe is subjected to parallelism, the results showed that these characters are much useful in determining relationships in the subtribe than those of pollinium.
