Abstract

Rhododendron is a flowering plant which is the largest genus in the Ericaceae family. Around 1,157 Rhododendron species have been assessed using the IUCN Red List criteria, and 316 are categorized as endangered species. Apart from maintaining species population numbers, conservation activities also need to pay attention to genetic aspects through DNA barcoding techniques. This research uses molecular in-silico methods using sequence data from NCBI's GenBank. This research aims to carry out an inventory of Rhododendron types based on genetic aspects, analyzing genetic variations and kinship relationships in the Rhododendron Genus. The resulting phylogenetic tree is divided into three clades in the Rhododendron group and one outgroup. The phylogenetic tree results show that the trnL-trnF DNA barcode can differentiate and identify up to species level in the genus Rhododendron. The trnL-trnF DNA barcode region of the Rhododendron genus is mostly conserved because it only has eight genetic variations, namely T71C, G225C, T245C, T229A, T485C, A491G, T705C, and A783G. The trnL-F gene is an informative chloroplast and can show the relationship between types.

Abstract

Bloodleaf plant, scientifically known as Iresine herbstii Hook, is an ornamental shrub with possible medicinal properties. Storage of simplicia is necessary to guarantee the accessibility of raw materials from I. herbstii. Prolonged storage of simplicia can impact its quality, including many non-specific factors. Indeterminate parameters suggest a relationship between the characteristics of Hook's I. herbstii simplicia during extended storage. This study seeks to ascertain the impact and correlation between the duration of storage of simplicia and the non-specific characteristics of I. herbstii simplicia. Moisture content, extractive value, and ash content were examined in samples with shelf lives of 0 month (IH0), 4 months (IH4), 10 months (IH10), 20 months (IH20), and 32 months (IH32). The acquired data were analyzed using DMRT (Duncan's Multiple Range Test) and MFA (Multiple Factor Analysis). The analysis results indicated that the storage duration impacted all parameters examined except acid-insoluble ash concentration. Prolonged storage of I. herbstii simplicia decreased the concentration of water-soluble and alcohol-soluble extractive value. At the same time, the water content and total ash content increased. The MFA analysis revealed a strong link between non-specific parameters and the duration of storage of I. herbstii simplicia, except for acid-insoluble ash concentration.

Abstract

Flipped classroom is a learning method that allows students to learn the material in advance at home according to the assignments given by the teacher. The intent of this study is to discover out whether the flipped classroom-based PBL learning approach impacts biology learning outcomes in class X SMA Negeri 4 Surakarta. This study conducted quasi-experimental research, using a post-test only control group approach. The population comes from class X students of SMA Negeri 4 Surakarta with the sample comprised of two classes generated using the cluster random sampling method, that is, phase E3 as the experimental class and phase E1 as the control class. Assessments, survey questionnaires, and observes are some of the data gathering procedures applied. Data analysis employs statistical techniques that are both descriptive and inference-based. The research results show that 1) The average cognitive learning results in the experimental class were 76.61, whereas the control group had 63.02. 2) The average affective test scores in the experimental class were 72.73, alongside the control class had 67.91. 3) The average results of psychomotor learning section in the experimental group had 67,36 along with the result from control group had 61,11. In accordance with the research findings, it can be inferred that flipped-based PBL learning classrooms influence biology learning outcomes in biotechnology material. Even though it has advantages, implementing flipped classroom learning can also potentially cause several obstacles.

Abstract

Biology learning in the 21st century is a challenge for teaching staff in guiding students in developing their abilities in accordance with the 4Cs and will produce competent students. One learning model that integrates 4C is project-based learning (PjBL) which is oriented to ethnoscience. The aim of this research is to determine gender differences in the implementation of ethno-PjBL learning. The research method is descriptive quantitative. Data analysis uses the Rasch model to analyze the suitability of the items to the model used and the t-test to determine the difference in cognitive scores of male and female students. The research results show that there are differences in learning outcomes between men and women. The average score for male is 68 and female is 73.5. The Levene Test results show 0.591 > 0.05, which indicates that the two gender groups have different learning outcomes. Male students complete assignments more quickly, tend to focus on content and are less interested in ethnoscience material, but their learning outcomes are no better than female students. Female students take longer to complete project assignments than male students. Female students are more interested in contextual learning presented through ethnoscience and structured design assignments through PjBL.

Abstract

The diversity of liverworts in North Sumatra is currently limited, highlighting the need for further investigations. Therefore, this study aims to collect and determine data on the liverworts of the Radulaceae family in the Batang Toru forest of North Sumatra. This forest was selected because it has very high rainfall with suitable humidity for the growth of liverworts. The samples were collected using an exploratory survey method, namely by collecting all the liverworts of the Radulaceae family along the Batang Toru forest hiking trails. The results showed 17 species of which three are new records for Sumatran liverworts namely Radula iwatsukii, Radula kinabaluensis and Radula obscura. The Radulaceae family was found as epiphytes on tree trunks and leaves. Based on the number of specimen collections, the most commonly found species was Radula javanica. In addition, Radulaceae in the Batang Toru forest was spread at altitudes between 800 and 1100 m.a.s.l and can be included in the Lower Montane Forest category.

Abstract

This study aims to examine the Implementation of Indigenous Knowledge-Laden Leaflets on Student Learning Outcomes on Global Warming Material. This study used a quasi-experimental method with a Nonequivalent control group design. This study used classes XA, XD, XE and XF, each class consisting of 36 students. In the class there is a selection of criteria, for class XA with high class criteria, class XD with medium class criteria, class XE with low class criteria, and class XF as a control class (Biology Teacher document). The research instrument is in the form of cognitive, affective, and psychomotor results. Data analysis of learning outcomes using one way anova test with normality test and homogeneity test. The results of the calculation of learning outcomes with one way anova test obtained a significance value (2-tailed) of (0.000) < (0.050) then the null hypothesis (H0) is rejected. And then the further test obtained a significance probability value of (0.917) > (0.050), therefore (H0) is accepted. This means that the treatment has an effect on student learning outcomes and the results of further tests have no effect on the learning outcomes of experimental classes (high, medium, and low clas).
