This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stabilit...

This research focuses on the development of contextual-based interactive learning media to improve mastery of reaction rate concepts and develop the character of high school students in remote areas. This learning media was developed to provide learning experiences that are relevant to everyday life, therefore the concepts of reaction rate are simpler to understand and apply in students. In addition, this contextual approach also aims to encourage character development, such as responsibility, d...

This research aims to formulate and examine the physicochemical characteristics and antioxidant activity of sacha inchi (Plukenetia volubilis L.) as a plant-based milk. Moreover, this research also aims to conduct organoleptic tests on the products. The sacha inchi milk is formulated with five ratios: SI1 (sacha inchi 1:10 parts water), SI2 (sacha inchi 2:10 parts water), SI3 (sacha inchi 3:10 parts water), SI4 (sacha inchi 4:10 parts water), and SI5 (sacha inchi 5:10 parts water). Organoleptic...
