21st-century skills demand highly intelligent and skilled human resources. Educational institutions are required to carry out reforms to prepare 21st-century Human Resources (HR). Strategies that can be done to shape 21st-century skills are through the implementation of HOTS-based Teaching and Learning Activities (KBM) assisted by innovative learning resources to produce human resources who can…
Plants in the Riparian Zone of Buluh Cina that grows along the Kampar river is one of the local potentials that can be utilized in learning to increase students' motivation, curiosity, and caring attitude towards the surrounding environment. However, educators do not use the environment as a source and learning media so that students' knowledge is limited. Therefore, a learning enrichment …
The availability of learning facilities and infrastructure is inadequate in the implementation of independent learning so that the textbooks owned by students cannot be used optimally as learning resources. Therefore, learning resources are needed that can make students play an active role in the learning process. One of the modules is teaching materials that are systematically arranged usi…
DNA barcode is one of the technique used for molecular identification with standardized short DNA sequences. In this study, the sequences used for DNA barcode analysis in jengkol (Archidendron pauciflorum) were from the trnL-trnL-trnF Intergenic Spacer region. The trnL-trnL-trnF Intergenic Spacer region was a noncoding region derived from the chloroplast genome. Archidendron pauciflorum be…
DNA barcoding is a molecular identification technique of organisms that uses short DNA sequences or DNA barcodes. The DNA barcode commonly used in molecular analysis is the trnL-trnL-trnF intergenic spacer which has a higher variation and mutation rate than rbcL and matK. This study aimed to analyze DNA sequences in the trnL-trnL-trnF intergenic spacer area of kabau (Archidendron microcarp…
Kabau in the Riau area is not widely cultivated and only grows wild in primary forest and secondary lowland forests in Indonesia. This condition makes kabau plants can be endangared. The development of technology to identify plant species can be performed molecularly using short pieces of DNA called DNA barcodes. Therefore, an exploration, such as building a database of DNA sequence from k…
Sour eggplant (Solanum ferox L.) is a thorny shrub from the Solanaceae family which is generally distributed in the tropics. DNA barcodes are short sequences that can be used in DNA barcoding techniques. One of the DNA barcodes in plants is the trnL_trnL_trnF intergenic spacer sequence which has high variability. The purpose of this study was to analyze and sequence DNA barcodes in the trn…
Mystus nigriceps is one type of fish that is used by the community as a consumption and economic need that causes a population decline in nature. One of the causes is excessive arrest. This study aims to find out the type of natural food of M. nigriceps in the Kampar Kiri River of Mentulik Village. Sampling is done using a net by fishermen. Observation of the contents of the fish hull is do…
Sentul plant (Sandoricum koetjape (Burm.f.) Merr.) It has chemical compounds that have the potential to be antibacterial. Actinomycetes have the ability to produce secondary metabolite compounds that have antagonistic properties to bacteria. The spread of actinomycetes is very wide in the rizosphere, which is around the rooting area of the plant. Actinomycetes are also found in the endophyt…
Andaliman (Zanthoxylum acanthopodium DC.) belongs to the family Rutaceae which is a spice plant typical of North Sumatra. The multiplication of andaliman sexually is still constrained because of the hard structure of the seed skin so it is difficult to germinate. The study aimed to determine the effect of hot water scarification on the increase in Z.acanthopodium sprout power, as well as d…
Endophytic bacteria are microorganisms found in plant tissues and are able to produce secondary metabolites, one of which -amylase inhibitor. The potential of plants is closely related to one of them with endophytic microbes in plant tissues. This study aimed to determine the potential of endophytic bacteria from rubber plants to produce -amylase inhibitors. Five isolates of endophytic bact…
Learning presentation media as a tool used to convey learning messages by educators to students. This study aims to develop a Prezi-based presentation media on the human circulatory system material to train critical thinking for class XI high school students. The development of Prezi media was carried out using the ADDIE model until the development stage. on the aspects of media and materials u…
Biology is one of the subjects that is not only delivered through theory and practical activities. As we know, learning biology is inseparable from practical activities, both in the laboratory and in nature. This practicum activity aims to make the material presented more easily understood and can instill and develop scientific skills, attitudes, and values to students. This study aims to produ…
This research was conducted to develop a guided inquiry-based practicum guidebook for teachers in teaching biology at the first year of senior high school students. It was conducted in october 2020 to december 2021. The model used in this research is a ADDIE model. Model consists of 5 (five) stages, namely analysis, design, development, implementation and evaluation. This research was carri…
This study aims to improve the critical thinking skills of students in class X IPA.1 SMA Negeri 1 Sabak Auh through the implementation of student worksheets based on problem based learning. This research method is Classroom Action Research which is carried out in 2 cycles. Each cycle consists of the planning stage, the implementation stage, the observation stage and the reflection stage. The re…
The 21st century generation is faced with technological advances in the digital world. According to the Regulation of the Minister of Education and Culture Number 22 of 2016, on the standard of the learning process it is necessary to use technology, information and communication in the form of learning media to deliver subject matter. Meanwhile, technological advances do not rule out the possib…
The existence and diversity of vegetation is one of the determinants of biodiversity and the quality of an ecosystem. The difficulty of finding natural ecosystems in urban areas does not eliminate the opportunity for students to get to know diversity. The built ecosystem can still provide an overview of diversity. This study aims to analyze the qualitative and quantitative parameters of ve…
