Abstract

This research is based on the problems that exist in the junior high school 18 Padang, namely the learning model that is less varied, student competence is still low, and learning is teacher centered. The effort that can be done is the application of learning cycle 5E learning model that contains scientific literacy to additives and addictive substances. The purpose of this study was to determine the effect of the learning cycle 5E with scientific literacy on the learning competencies of Grade VIII students at junior high school 18 Padang. This research is a quasi-experimental study with a randomized control group posttest only design. The study population was eighth grade students of SMP Negeri 18 Padang 2018/2019 academic year consisting of eleven classes. The research sample was taken using purposive sampling technique, the results of which were selected class VIII.3 as the experimental class and class VIII.4 as the control class. The results of data analysis found that the competency data of knowledge, attitudes, and skills of homogeneous and normal learners. Hypothesis test results are known that knowledge competencies (2,60> 1,67), competency attitudes (4,26> 1,67, and skills competency (3,33> 1,67) So it can be concluded that the learning cycle 5e model with scientific literacy has a positive effect on participants' learning competencies in additives and addictive substances in the junior high school 18  Padang. Keywords: learning cycle 5E, sains literation, learning competency.

Abstract

Hydroponic cultivation using a wick system is one of the techniques used to increase the production of spinach (Amaranthus hybridus L.). One of the disadvantages of hydroponics is the occurrence of nutrient deposition, to reduce nutrient deposition in the wick system is to apply nanotechnology to break down particles in the planting medium and nutrients used, that the particles become smaller and more easily absorbed by plants, and reduce precipitation in the wick system. This research was conducted using the RAL method (Completely Randomized Design) which consisted of 6 treatments and 4 replications and namely Control (Well water + AB Mix), P1 (Nano technology water + 100% AB Mix), P2 (nano technology water + 25% POC+75% AB Mix), P3 (nano technology water+50% POC+50% AB Mix), P4 (nano technology water+75% POC+25% AB Mix), P5 (nano technology water+100% POC). The data obtained were analyzed by means of variance (ANOVA) and followed by the DMRT test at 5% level. The results of this study are that there is an effect of the use of nano technology liquid organic fertilizer on the growth of spinach which can be seen in the highest plant at P2 with 29.975 cm, the highest number of leaves is at P2 with 34 leaves, the highest leaf area is in the control with 13,71 cm2, the wet weight the highest was on P1 with 17 gr, the highest dry weight was on P2 with 1.3 gr. The use of nano technology liquid organic fertilizer has an influence on the growth of green spinach which is cultivated hydroponically.

Abstract

Hydroponics is a method of agriculture in which earth is not used. Among the plants amenable to hydroponic cultivation is red lettuce. One disadvantage of hydroponic cultivation is the occurrence of nutrient deposition, particularly in the wick system, where the nutrient water does not move. A technique that can lessen the amount of nutrient deposition that occurs in hydroponic systems is required in light of the aforementioned issues. Nanotechnology is one of the technologies developed. The five treatments and four replications in this study were P1 = AB Mix 100 percent, P2 = AB Mix 75 percent + POC Nano 25 percent, P3 = AB Mix 50 percent + POC Nano 50 percent, P4 = AB Mix 25 percent + POC Nano 75 percent, and P5 = POC Nano 100 percent. ANOVA (Analysis of Variance) was used to analyze the data, and the Duncan's New Multiple Range Test (DMRT) test at level 5 followed. The effects of nanotechnology-enhanced liquid organic fertilizer on red lettuce growth, including height, leaf area, number of leaves, fresh weight, and dry weight, were examined. The highest average plant is at P3 with a plant height of 36.42 cm, the highest average number of leaves is at P3 as many as 11.25 strands, the widest average leaf is at P4 with an area of ​​40.25 cm2, the average weight The highest wet weight was P4 with a weight of 17.01 g, and the highest average dry weight was P2 with a weight of 1.32 g.

Abstract

The germination process of expired rice seeds is quite difficult because the seeds have decreased in quality due to expiration. Rice seeds (Oryza sativa L.) expired require increased viability to increase their germination. One way to increase seed viability is to use an invigoration material in the form of KNO3 by adjusting the soaking time and the concentration of KNO3 used. This study aimed to determine the best soaking time and KNO3 concentration to increase the viability of expired rice seeds. This research was conducted at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University in May-June 2022. This study used a completely randomized design (CRD) with two treatment factors. The first factor is the length of immersion with 3 levels, namely 12 hours, 24 hours, and 48 hours. The second factor is the concentration of KNO3 with 5 levels, namely 0%, 1.5%, 2%, 2.5%, and 3%. Each treatment combination consisted of 4 replications. The parameter observed is the vigor index. The results showed that the treatment of KNO3 concentration had a significant effect on the parameters of the vigor index of expired Cisokan kuniang rice varieties. The immersion time had no significant effect on the vigor index parameter. The interaction between immersion time and KNO3 concentration significantly affected the vigor index parameter.

Abstract

The use of fertilizers and pesticides provides various side effects such as environmental pollution and higher production costs due to the high prices of fertilizers and pesticides. Therefore it is necessary to look for other alternatives to control plant diseases. One of the safe and environmentally friendly control measures is to use biological control agents. Fluorescent pseudomonads are antagonistic bacteria that are widely used as biological agents for fungi, pathogenic bacteria and viruses. Biological control using fluorescent pseudomonads has been studied for its effectiveness in suppressing plant diseases. This study aims to collect and analyze articles related to the potential of fluorescent pseudomonads in controlling plant diseases. This type of research is research that uses the literature review method and collects literature using internet sources from the Google Scholar database. The stages consist of identification, screening, eligibility and acceptance. Based on the articles collected, it was found that fluorescent pseudomonads are potential and effective in controlling various plant diseases.
