Abstract

ABSTRAK   Kirinyuh (Eupatorium odoratum) mengandung senyawa alkaloid, flavonoid, tannin, dan seskuiterpen yang bersifat insektisidal. Penelitian ini bertujuan untuk mengetahui aktivitas insektisidal ekstrak etanol daun kirinyuh terhadap wereng coklat dan nilai LC50-24 jam. Penelitian menggunakan rancangan acak lengkap (RAL) dengan menvariasikan  konsentrasi ekstrak etanol daun kirinyuh, yaitu 0%, 3%, 6%, 9% dan 12%. Data hasil penelitian dianalisis dengan analisis  regresi, probit, dan  Anava yang dilanjutkan BNT 5%. Dari hasil penelitian ini diketahui bahwa ekstrak etanol daun kirinyuh mempunyai aktivitas insektisidal terhadap wereng coklat, semakin tinggi konsentrasi ekstrak etanol daun kirinyuh  maka semakin tinggi pula tingkat kematian wereng coklat. Nilai LC50-24 jam adalah sebesar 14,905%. Berbagai konsentrasi ekstrak etanol yang diberikan memberikan pengaruh yang berbeda terhadap tingkat kematian wereng coklat.   Kata kunci:  aktivitas insektisidal, kirinyuh (Eupatorium odoralum L.), wereng coklat

Abstract

E-Booklet learning resource from study results for enrichment materials are still limited . This study aims to determine the quality and feasibility of the antioxidant activity of red dragon fruit juice (Hylocereus polyrhizus) E-Booklet as an enrichment material for class XI of cell bioprocessing. The subjects of this study were students of class XI IPA SMA Negeri 5 Yogyakarta. E-Booklet development is adapted from 4D models (define, design, develop, and disseminate). Likert scale questionnaire  was used to assess the product and the guttman scale questionnaire was used to determine student responses. Product assessment was carried out by media experts, material experts, and Biology teacher at SMA Negeri 5 Yogyakarta. The product trial data was taken from 34 students of SMA Negeri 5 Yogyakarta. Data from the assessment questionnaire were analyzed descriptively to determine the quality of the E-Booklet. The results of the assessments from material experts, media experts and biology teachers indicate that the quality of the E-Booklets that have been arranged is in the very good category, so it is appropriate to proceed to the product trial stage. The student responses indicate E-Booklet was in the very good category.

Abstract

Students are required to be able to master 21st-century skills in learning biology. One of the demands of 21st-century skills is the ability to solve problems and biology learning outcomes. This study aims to analyze the effect of Problem-Based Learning model on problem solving ability and cognitive learning outcomes of biological science with literature study analysis. This research is a literature study with a narrative review type. The scientific articles used in this study amounted to 31 articles, consisting of 2 international journals, 18 accredited national journals, 3 unaccredited national journals, 3 proceedings, and 5 theses. The search for scientific articles was carried out through www.scholar.google.co.id and http://www.doaj.org. The data analysis technique was descriptive. The results showed that the Problem-Based Learning model had an effect on the ability to solve problems and cognitive learning outcomes of biological science.
