Abstract

Abstract: The test instrument is a measuring tool in the form of a number of questions that require answers to measure a person's level of ability. The purpose of this research is to produce a valid test instrument on ecosystem material in class X SMA/MA. This research was conducted at the Biology Education Campus, FKIP Riau University and SMAN 1 Pekanbaru. This type of research is development research using the ADDIE model, which consists of the Analysis, Design, and Development stages. The data collection instrument used was a validation sheet. The validation sheet consists of 3 aspects, namely material aspects, construction aspects, and language aspects. The three aspects include material aspects with an average of 3.95 very valid category, construction aspects with an average of 3.70 very valid category, language aspects with an average of 3.91 very valid category. The aspect that received the highest score was the material aspect with an average score of 3.95 with a very valid category. Based on the results of the study, it can be concluded that the test instrument on the ecosystem material for class X SMA/MA that has been developed is included in the very valid category in all aspects with an average validity value of 3.85, so that the test instrument that has been developed can be used in learning biology.Key Word: Test Instrument, Ecosystem.

Abstract

The use of tin (Ficus carica L.) in Indonesia is still very limited and is generally only used as bonsai saplings. Tin plants can be propagated vegetative, namely the cutting technique. Selection of appropriate biological fertilizers is one of the strategies for the success of cuttings. This study aims to analyze the effect of various biological fertilizers on stem cuttings of tin plant. This research was conducted in July-October 2022, located at CV. Martabe Prima Lestari, Lubuk Raya Village, Padangsidimpuan Hutaimbaru District. The study was arranged by using Randomized Block Design (RBD), consisting of 4 treatments: P0 (control, without biological fertilizers), P1 (Trichoderma sp. 15 grams), P2 (promoles 12.15 grams) and P3 (15 grams mycorrhiza). and 6 replicates. The data obtained were analyzed by ANOVA and if there were differences, it would be continued with Duncan Multiple Range Test (DMRT). Results: Promol 12 and Micoriza, showed no significant difference in the percentage of live cuttings. Observation of time of bud break showed that the biological fertilizer treatment had no significant effect. Number of shoots showed that biological fertilizers had no significant effect on number of shoots. The average number of leaves showed that at 4 WAP(P0) was not significantly different from P1, but significantly different from P2 and P3. P1 is not significantly different from P2 but significantly different from P3, P2 is not significantly different from P3. It can be concluded that the treatment of biological fertilizers has a significant effect on the number of leaves on tin plants.
