Abstract

The pineapple plant cultivated in Indonesia is very diverse and is a perennial plant. Public awareness of the nutritional content in pineapple can increase the production and economic value of the fruit. Therefore, large-scale pineapple production in a relatively short time is needed, and one way to achieve this is through pineapple propagation via tissue culture.  In this study, pineapple was propagated using shoot explants. Shoot culture, or shoot induction, is one method for propagating plants in vitro. Shoot culture is the most common propagation method because shoots contain a lot of meristematic tissue (which is still actively dividing), resulting in a higher percentage of success for tissue culture.  This study used a completely randomized design (CRD) with the following hormone concentrations: 0 ppm NAA + 0 ppm Kinetin, 0.25 ppm NAA + 3.0 ppm Kinetin, and 0.25 ppm NAA + 4.5 ppm Kinetin. The results showed that explant growth occurred in every concentration, with 100% of all treatments producing shoots. Nevertheless, there were variations in the number of leaves formed in each treatment and observation time, indicating the influence of hormone concentration on the vegetative development of the explant.

Abstract

This study aims to determine the percentage of butterfly pea flower extract that can produce quality yogurt. In making this yogurt, variations in the extract concentration of 5% and 10% of the butterfly pea flower with a fermentation time of 18 hours, in addition to variations in the addition of honey to the 10% extract and 30 grams of sugar to the 5% extract, and yogurt without giving the butterfly pea extract. The main ingredient used is UHT milk with 200 ml each. Organoleptic testing was carried out to make yogurt in order to find out the level of consumer preference for the exact composition of the butterfly pea flower extract. Samples YBT1 (control), (YBT2 (preferred), YTBT (disliked).

Abstract

Biology learning, particularly on the topic of Plantae, often poses difficulties for students due to the complexity of scientific terminology, morphological diversity, and the limited use of innovative learning media, which are still predominantly based on textbooks and static images. This condition calls for innovative media that not only present information accurately but also provide a more interactive learning experience aligned with the characteristics of the digital generation. This study aims to develop an E-Encyclopedia based on herbarium collections as a learning medium for biology in the Plantae topic while supporting the digitalization of botanical knowledge. The research employed the 4D development model (Define, Design, Develop, Disseminate). The subjects of the study included teachers and students at SMA PGRI 1 Palembang. The results of the define stage revealed the lack of innovative media and the difficulty students faced in understanding Plantae concepts. The design stage produced a prototype of an E-Encyclopedia based on herbarium documentation featuring interactive elements and plant specimen visualization. Validation results from material, media, and language experts indicated a very valid category with an average expert validation score of 91.9%. The practicality test through teacher responses achieved 91.4% (very good category), while student responses reached an average of 93,3% (very good category). The effectiveness test using pretest and posttest data from 38 students showed an improvement in learning outcomes, with an average pretest score of 55 and a posttest score of 82, resulting in an N-Gain of 0.56 (moderate category) and a significant t-test result (p < 0.05), confirming the media’s effectiveness. These results indicate that the herbarium-based E-Encyclopedia developed not only enriches digital learning resources but is also proven to be valid, practical, and effective in improving biology learning outcomes, especially on the Plantae topic. Moreover, this product supports the conservation of botanical knowledge, facilitates access to plant biodiversity data, and enhances scientific literacy in the digital era.
