Abstract

The purpose of this study was to develop online methodology for high school biology practicum instructions and their effectiveness on students' science process skills. The subjects in this study were students of class X IPA SMA Al-Hamzar Tembeng Putik, Wanasaba District, East Lombok Regency. The type of research used is development research that produces products in the form of high school biology practicum instructions with online methods. The development procedure carried out in this study is in accordance with the steps based on the Borg & Gall model, with the following stages: 1) research and data collection; 2) planning; 3) development of the initial product draft; 4) initial field trials; 5) revised trial results; 6) field test of the main product; 7) product revision; 8) wide-scale field trials / feasibility tests; 9) final product revision; and 10) dissemination and implementation. This research is only up to the 7th stage. The research instrument used was the observation sheet and the validation sheet. The results showed that the high school biology practicum guide developed using the online method, based on the results of the validation that has been done, the score is 2.96 which is included in the valid category. As for the students' science process skills, the score was 70.5 in the skilled category, 81.5 in the highly skilled category, and 92 in the very skilled category.

Abstract

This study aims to: 1) obtain growth regulators that are easy to obtain at low prices, because synthetic growth regulators are relatively expensive for novice researchers and are very difficult to obtain; and 2) to find out whether household waste can be used as a plant growth regulator in vitro which has been widely used and has been successful conventionally in several types of plants. The method used in this study was experimental, using a completely randomized design (CRD) with three replications. The media used was MS media by adding growth regulators from household waste with a concentration of (0-3) mg/L. The parameters in this study were the number of shoots and roots. The data obtained were then analyzed qualitatively, because the resulting data was not normal and not homogeneous. The results showed that the highest number of shoots was at a concentration of 2 mg/L organic waste growth regulator, with 5 shoots and 15.7 roots, with 8 days after planting on chrysanthemum growing media.

Abstract

This study aims to obtain the right formula for using Liquid Organic Fertilizer (LOF) from household waste for the growth of Dendrobium sp. The method used was an experiment with a Completely Randomized Design (CRD), with three replications. The medium used is MS media by adding liquid organic fertilizer from household waste with a concentration of (0-3) mg/L. Parameters in this study were the fastest day of emergence of shoots, number of shoots, and roots. The data obtained was analyzed using the Kruskal-Wallis test, because the data obtained was not normal and not homogeneous, a descriptive analysis was used. The results showed that the highest number of shoots was obtained at a concentration of 3 mg/L of organic waste growth regulator with a total of 4.3 shoots and 15.7 roots at a concentration of 2 mg/L the fastest day for shoots to appear after planting was 12 days on plant media and roots appeared on 8th day after planting on Dendrobium sp.
