Abstract: This research was conducted to develop a guided inquiry-based practicum guidebook for teachers in teaching biology in the class XI of senior high school students. It was conducted in September 2018 to January 2019. The model used in this research is a ADDIE model. Model consists of 5 (five) stages, namely analysis, design, development, implementation and evaluation. This research was carried out until stage 3 (three), namely the development stage. The stage of analyze, design, development, internal validation and limited trial phase I was carried out in the Biology Education Laboratory FKIP University of Riau. External validation was carried out in SMA Negeri 1 Pekanbaru and SMA Negeri 8 Pekanbaru. The limited trial phase II was carried out in SMA Negeri 8 Pekanbaru. The book is validated based on four indicators, namely: book format and graphics, illustrations and pictures, language, and content eligibility. The overall results of the validation obtained an average of 3,47 with very valid categories. The results of the limited trial phase I have an average of 3,59 with very good categories and the results of the limited trial phase II have an average of 3,59 with very good categories. The book produced in this study has a very valid and very good categories so that the practicum guidebook is broad to hold the teacher’s grip in proper and can be implementation of practical activities.Key Words: Practicum guidebook, Quided inquiry, Biology learning

Abstract

Abstrack: The use of growth regulators in one way to accelerate plant growth and develoment. Growth regulators that are naturally present in plants are auxin, geberelin, cytikinin, abscisic acid, and ethylene. Auxin hormone is a hormone that regulates root growth in plants, can be produced by plants or added from outside (exogenous hormone). This reseach was conducted to determine the concentration of natural growth regulators onion extract which can show the best concentration of root growth and shoots on stem cutting as a design for high school biological handout teaching materials. This reseach used an experimen method with a complete randomized design (RAL) consisting of 6 treatments and 4replications, so that a total of 24 treatments were obtained. The parameters observeb in this reseach incleded the percentage of live cuttings, age of shoots, number of shoots, shoot length, and primary root length. Based on the analysis of variance (ANAVA) at the level 5%, the administartion of shallot extract significantly affected each treatment and it wasfound that concentration of 80% was the best teratment for the parameter age of shoots, number of shoots, shoot length, and primary root length.Kata Kunci: Growth Regulator, Shallot (Allium cepa L.), Auxin, Rose Plant.
