Abstract

This study aims to determine the level of effectiveness of online learning for students or cadets at the Bumi Akpelni Polytechnic semarang, with a total of 516 respondents. Research activities were carried out during the implementation of Study From Home during the Covid-19 pandemic. The application support used in this online lecture is zoom meetings, google meet and whattapp groups. This study uses a descriptive qualitative method that aims to describe the condition of natural objects with triangulation data collection techniques. From the results of the study of 516 cadets or students, it can be concluded that students or cadets choose at home as a place to learn during the pandemic, then it can also be explained that the most effective tool is a smartphone then respondents choose to use the Google Classroom application as the main alternative in online learning but it is also necessary to pay attention to the geographical conditions of each and

Abstract

Diaper waste containing the nutrient NPK can increase plant growth. This research aims to find out whether there is an effect of disposable diaper hydrogel on the growth of rose plants (Rosa sp.) and to find out the weight of the hydrogel which has the best effect on the growth of rose plants which is then prepared as a biology learning resource in the form of Student Worksheets. The research used a Completely Randomized Design (CRD) with 1 control and 3 treatments with 4 repetitions. The research was carried out for 2 months with the observation parameters of stem height, number of leaves, and number of petals of roses (Rosa sp.) which were analyzed using the One-Way ANOVA Test for rose plant stem height parameters and the Kruskal Wallis Test for the parameters of number of leaves and number of petals roses. The results of this research show that there is an influence of the weight of disposable diaper hydrogel on the growth of rose plants. It is known that in the analysis of stem height growth data, the calculation of Fcnt = 10.85 > F(0,05) (3,12) = 3.49. Analysis of leaf number data shows that Hcnt = 11.35 > X(0,95) (3) = 7.81. Likewise, analysis of the data on the number of petals shows that Hcnt = 10.04 > X(0,95) (3) = 7.81. The best hydrogel weight was in treatment 3 (P3) for all observed parameters. The results of this research can be used as a learning resource in the form of Student Worksheets on development and growth material in class XII plants.
