Abstract

Watering is an important activity as a plant growth process in order to survive. Determination of plant water needs is important to do, because plant water needs are the main limiting factor for plant productivity. Plant water needs can be determined based on the value of water content in the field capacity of the growing media. The aim of this study was to examine the effect of different volumes of watering on increasing growth and production of lettuce (Lactuca sativa L.). The study was carried out for 7 days with 3 treatments of watering volume, with each treatment carried out 6 times. The treatment tested was giving a different volume of water to each lettuce plant with three levels. Observations in this study were leaf cross-sectional area, number of leaves, and plant fresh weight. Experimental research with a qualitative descriptive approach and statistical data processing with the Kruskal Wallis Test. The results of data analysis showed that there was a relationship between the size of the volume of water in watering and the growth of lettuce plants

Abstract

Practical activities are a learning method that can involve students in constructing their own understanding. A good practicum activity must be guided by a structured instruction sheet or student worksheet that is able to lead students to understanding. The purpose of this research is to produce a worksheet for students of osmosis practicum that is reconstructed using Vee diagrams. The method used in this research is descriptive qualitative method. The results of this study indicate that the LKPD of osmosis practicum that has been analyzed has deficiencies in the purpose or focus of the question made, besides that there are still deficiencies in procedures and data transformation so that it does not lead to the desired conclusion. Reconstruction was carried out using Vee diagrams so that the resulting LKPD for osmosis practicum had all the criteria for the Vee diagram assessment score. Based on the results of the scores obtained on the reconstructed osmosis practicum LKPD, it shows that the LKPD is feasible and can be used in guiding students in osmosis practicum activities. From the results of the reconstruction carried out, it is hoped that the reconstructed products using Vee diagrams can guide students in constructing their own understanding. In addition, in the future, the reconstruction of LKPD using Vee diagrams can be further developed.
