Abstract

The growth of Chili pepper (Capsicum chinense Jacquin.) is affected by biotic and abiotic stresses. Abiotic stress such as waterlogging increases the expression of ACS (1-aminocyclopropane-1-carboxylic acid synthase) enzyme. This enzyme plays a great role in the process of ethylene biosynthesis and encoded by multiple genes. Waterlogging causes hypoxia condition. One of ACS enzymes that responds to hypoxia condition is ACS2. The different respond to hypoxia stress among plant was assumed to be caused by a different structure of the ACS2 enzyme. This study aimed to identify and confirm the active site of Capsicum chinense Jacquin ACS2  using modeling and in silico docking. The result of the three-dimensional (3D) structure modeling showed 91% similarity of Capsicum chinense Jacquin ACS2 with the structure of the tomato (Solanum lycopersicum L.). The Capsicum chinense ACS2 confirmed five active sites that bind to the substrates asparagin396B, valine397B, thyrosine152B, threonine128B, and thyrosine92A.

Abstract

This research discusses the development of teaching materials needed in the world of education. This research uses a skinative research method with secondary data methods, namely through literature studies. Teaching materials are one of the most important components in the learning process, and can help students learn more easily. Instruction consists of two categories: printed instructions and non-printed instructions. One type of printed teaching material is textbooks. Teaching materials can be defined as any type of material used to help teachers or instructors carry out teaching and learning activities in the classroom. Print teaching materials through the media of books, handouts, maps, magazines, etc. Non-print teaching materials audio programs, display teaching materials, overhead transparencies (OHT) models, videos and computer-assisted teaching materials. Knowledge of teaching materials is needed so that students can apply it in the form of product development or research related to teaching materials. In learning biology, delivery requires teaching material media as a lat in channeling knowledge.

Abstract

Hybridization is the main method for obtaining genetic diversity and breeding new varieties of tea. The purpose of this research is to determine the morphological potential of each progeny from crossing between male and female parents which can then be used as a source of information in developing high quality superior tea clones through tea breeding activities. Male and female parents with the desired traits were crossed to form genetic diversity. 34 progenies resulted from crosses formed from crossing 4 male parents and 3 female parents. All parents and progeny were characterized morphologically and yield components. Data on morphological characters and yield components were analyzed descriptively. Correlation analysis and Principles Component Analysis Biplot (PCA Biplot) were also performed using R software. Male tea parents and female tea parents are in different groups based on morphological characteristics. Progeny-17, Progeny-18, Progeny-4, Progeny-5, and Progeny-27 had a higher total number of shoot and potential yield per bush compared to the other progenies.
