Abstract

This study aims to determine the effect of the concentration of rice husk charcoal and cow manure on the growth of Dayak onions (Eleutherine americana Merr.) And produce Student Worksheets for class XII SMA. This research was conducted in Jayapura Village, Siak Regency, in October-December 2019. This study used an experimental method with a completely randomized factorial design consisting of 2 treatments using a combination of rice husk charcoal and cow manure and each treatment was repeated as much 3 times. The parameters of this study were leaf length, number of leaves, number of tillers, leaf wet weight, and tuber wet weight. The design of LKPD development refers to the stages of the Problem Based Learning model which are simplified into the Analyze and Design stages. The results showed that the combination of rice husk charcoal and cow manure can increase the growth of Dayak onions significantly affected at a dose of 90 gr/tan (S2K2) with the best treatment on each parameter observed. The results obtained will be used as a development material for the growth and development of Class XII SMA in KD 3.1 and 4.1. The results of the design of learning tools in the form of Syllabus, RPP and LKPD.

Abstract

This research aims develop weblog media about environmental contamination material to determine the reflective thinking skills of junior high school students. The development of a weblog as a learning medium used the ADDIE model. In this research up to the development phase. The weblog design has gone through the validation phase. The validation was performed by 4 validators using a validation sheet. Student responses were collected using a questionnaire and reflective thinking skills using multiple choice test. The developed weblog has been tested on 20 students of 8th grade. The results showed that the use of blogging media positively impacted students' reflective thinking skills, given the increase in mean pre-test and post-test scores from a score of 69.5 to 82. The increase in reflective thinking skills was seen in of the three indicators of reflective thinking, namely reacting from 79% to 81,5% in high category, elaborating from 50% in low category to 75% in high category and contemplating from 67% in normal category to 78,4% in high category. The use of blogging media to reinforce thinking skills is also supported by the results of student responses with an average result of 92,8% for aspects of reflective thinking.

Abstract

This study aims to determine the growth of tilapia (Oreochromis niloticus) with the use of Azolla microphylla feed and its potential to produce a module design on the material for growth and development of living things in class XII odd semester KD 3.10 and KD 4.10.This research was conducted from May to August 2020 at Danau Selais LPPM Riau University. This study used 2 stages, namely. Phase I research used quantitative descriptive to determine the growth of tilapia on Azolla microphyla feed with different feeding percentages. Fish were grouped into 3 treatments and 1 control. Fish are reared in different cages with different percentage of feeding. The research parameters included absolute length growth, absolute weight growth, nisbi  growth rate, and survival rate.Phase II research is a module teaching material design that uses 2 stages, namely, the Analyze and Design stages.The results of the experimental stage of research, feeding Azolla microphylla affected the growth of tilapia (Oreochromis niloticus). P3 treatment (giving 5% Azolla microphylla from fish biomass) is the best dose in increasing the growth of tilapia. Resulted in the absolute length growth of 4.24 cm, absolute weight 11.72 g, 4.68% relative growth, 4,68% specific growth rate and 99.4% survival rate. The P3 treatment resulted in a growth which was much lower than the P0 treatment (control).

Abstract

This research aims to determine the effect of using flip chart on students' scientific literacy on environmental pollution material. This development research used ADDIE model. This research was carried out until the development phase. The flip chart that have been produced validated by using validation sheets by 4 validators who expert on media and material, then tested on 20 grade VIII junior high school student. The data of Students’ responses about flip chart were collected by using a questionnaire and students’ science literacy were collected by using multiple choice test. The results of the research indicated that Flip Chart was valid with score 88,3% (very valid) in material and 87,5% (very valid) in media. The result of this result also indicated that there was an increase in the mean score of pre-test and post-test from 62 (low) to 81 (high). It illustrated that there was a strengthening of science literacy on the competence to explain phenomena scientifically from 61.25% (low) to 87.5% (very high), the competence to design and evaluate scientific enquiry from 53.75% (low) to 71.25% (enough), and the competence to interpret data and evidence scientifically from 80% (high) to 87.5% (very high). This result was supported by student questionnaires when using flip chart, which is 88.1, it shows that flip charts can be used as a means of strengthening student scientific literacy.

Abstract

Regulation of the Minister of National Education of the Republic of Indonesia Number 16 of 2007 concerning Academic Qualification Standards and Teacher Competencies states that one of the competencies of high school biology teachers is the competence to properly design and implement practicum. Biology Education students as prospective biology teachers must master these competencies. The existence of independent learning resources can be used as a reference for prospective student teachers in studying material related to practicum activities. This study aims to produce independent learning resources in the form of videos. This research was conducted at the PMIPA Laboratory FKIP Riau University, SMAN 8 Pekanbaru and SMAN 15 Pekanbaru in April-December 2020. The type of research used was Research and Development (R&D) with the ADDIE model. The instruments used in this study were the validation sheet and response questionnaire. The results of the video validation obtained an average value of 3.57 with a very valid category. The results of the limited trial phase I obtained an average value of 3.64 in the very good category, while the results of the phase II trial obtained an average value of 3.43 in the very good category. Based on the results of the validation and trials, it shows that the video of the design and implementation of the biology practicum developed can be used as an independent learning resource for prospective biology teachers.

Abstract

This research was conducted to determine the effect of mung bean extract on the quality of Nata de cassava and poster design of biotechnology subject matter at the XII grade high school level in June-August 2020. This research was conducted in 2 stages, namely the experimental stage: the effect of giving mung bean extract to the quality of Nata de Cassava and the second stage of poster design: analysis of the potential development of biotechnology teaching materials for class XII high school level. This study used an experimental method by conducting experiments at the Laboratory of the Faculty of Mathematics and Natural Sciences (FMIPA), Pekanbaru. Sampling was carried out with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The parameters in this study were thickness analysis and acidity (pH) analysis. Based on the results of the Analysis of Variance (ANOVA) at the 5% level, giving green bean extract showed a significant effect on the quality of Nata de cassava. Giving green bean extract of 600 ml gives an increase in the quality of the best Nata de cassava and based on the analysis of the potential research results can be used as a poster design for class XII high school level biotechnology material.
