Green betel leaves and kaffir lime have long been used by the community in everyday life and can be used as vegetable insecticides, because of the stage of leaf development that causes changes in volatile compounds. Towling of young, mature and old leaves is constantly feared to trigger growth in growth and development of plants. The purpose of this study was to determine the change in esse…
DNA barcoding is a technique that uses standard short pieces of DNA or also known as DNA barcodes whose ability has been tested to distinguish at the species level. One of the DNA barcodes in plants is the DNA barcode on the matK gene. The purpose of this study was to analyze the DNA barcode sequences in the matK gene area of petai (Parkia speciosa) taken from Siak Hulu District, Kampar Re…

This study aims to determine the diversity of ferns in Pangean District, Kuantan Singingi Regency based on morphological characters. This research was conducted using the exploratory method. A total of 15 species of ferns were found and identified based on their morphological characters. The results of th…
Rice black bugs is one of the insects that like to suck rice plants. These insects suck rice plants in the vegetative and generative phases and have caused huge economic losses. This research aims to identify and study the appropriate of rice black bugs species from several rice fields in Lubuk Sikarah District, Solok City, West Sumatra. This research uses a sampling method using light trap…
Andaliman is a typical Batak plant belonging to the Rutaceae family. Besides being used as a spice, andaliman also has potential in the pharmaceutical and food industries. Sexual propagation using seeds is still very low. Andaliman seeds have physical dormancy due to the hard seed coat structure so that the imbibition process cannot run. This study aims to determine the concentration and d…
Education in the 21st century demands modern and professional education management with an academic and educational nuance. So the need for enlightenment and empowerment of every type and level of education. One of these enlightenment and empowerment can be done from the aspect of procurement of teaching materials, teaching materials can be pursued by developing teaching materials continuo…
Faculty of Teacher Training and Education (FKIP) Riau University (UNRI), especially the Biology Education Study Program has implemented Environmental Science and Disaster Mitigation course which aims to provide insight and understanding to students so that they are more familiar with the environment and are responsive to problems that arise. In realizing these goals, of course, requires ap…
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.
