<![CDATA[Students' understanding of concepts is a very important factor in the success of learning. But in reality, Indonesian students' conceptual understanding is still low. The factor of low understanding of students' concepts is because students are not actively involved in problem solving activities. Student involvement can be trained by using one of the communication tools in the form of interesting learning videos to get students' attention in learning activities. This research is a survey research as a first step in developing problem solving learning videos. The benefit of this research is to find out what students currently need in science learning and how much students need to develop problem solving based learning videos. The subjects used in this study were junior high school students with a sample size of 48 students selected based on a region. This needs analysis includes 4 indicators, namely a) analysis of learning problems; b) analysis of learners; c) analysis of objectives; d) analysis of settings. Based on the results of this study, information was obtained that the development of problem solving based learning videos was feasible to be developed as a science learning media to train students' conceptual understanding in the city of Pekanbaru]]>

<![CDATA[Currently, the obstacles faced in learning process are found to be low student interest in learning. The main factor contributing to low student interest in learning is influenced by the lack of variety of learning media used by teachers in schools. The use of augmented reality (AR) in education is classified as an important research topic, although it is still being studied in its early stages. The purpose of this research was to develop learning media using e-magazine based on an AR to increase students' interest in learning. The developed e-magazine was carried out using model of ADDIE (analysis, design, development, implementation and evaluation). Parameters in this study was focused on the quality of e-magazine and students’ interest in learning. Testing students' interest in learning was conducted by using a questionnaire and given directly to students. The experiments were carried out in the control class consisting of 36 students and the experimental class consisting of 36 students. Results of the study found that the development of AR-based e-magazines were obtained in relatively good category. This value was supported by the validation value found in the very valid category. Analysis on the didactic, constructive and technical aspects were obtained a score of 3,82, 3,85 and 3.78, respectively, with a very valid category. The results also showed that the use of AR-based e-magazines could be increased students' interest in learning and students' interest in learning was obtained at a value of 0.342 in the high category. Thus, the use of AR-based e-magazines as digital learning media can be used in the learning process.]]>

<![CDATA[Pemanfaatan bakteri endofit sebagai penghasil senyawa metabolit sekunder sangat menguntungkan. Kandungan metabolit sekunder yang terdapat di dalam jaringan tumbuhan serta dalam bakteri merupakan potensi yang memberikan banyak manfaat dalam bidang pertanian. Penelitian ini bertujuan untuk mengisolasi bakteri endofit dari daun dan kulit batang tanaman Laban (Vitex pubescens Vahl) dan uji antibakteri. Bakteri diisolasi menggunakan media HVA. Karakteristik bakteri endofit diamati secara makroskopis, mikroskopis, dan melakukan uji katalase serta untuk uji antibakteri menggunakan bakteri patogen Erwinia carotrova. Jumlah isolat endofit yang berhasil diisolasi berjumlah delapan isolat (empat isolat dari daun laban dan empat isolat dari kulit batang laban). Karakterisasi dilakukan pada delapan isolat endofit yang dihasilkan bahwa isolat memiliki ciri-ciri yang berbeda baik secara makroskopis, mikroskopis, dan semua isolat endofit dari tanaman laban menghasilkan enzim katalase (uji +). Hasil aktivitas antibakteri menunjukkan tujuh isolat bakteri endofit memiliki aktivitas antibakteri terhadap erwinia carotrovora. Tanaman laban kaya akan keragaman bakteri endofit. Isolate bakteri endofit terisolasi 8 spesies yang berbeda (DA45, DA46, DB15, DB16, KBC1, KBC2, KBC3 dan KBC4). Bakteri endofit yang berasosiasi dengan tanaman berperan penting dalam kesehatan tanaman.]]>

<![CDATA[This study aims to look at the effect of pictorial glossaries on the creative thinking abilities of class X students, SMAN 1 Teluk Kuantan on the subject of the Plant World. This type of research was quasi-experimental research. The study population was all high school grade X students as a hypothetical population. The research sample consisted of 67 people consisting of 33 students in class X MIPA 1 as a control class and 34 students in class X MIPA 2 as an experimental class. Data collection techniques used observation sheets. The result shows that average score of the creative thinking ability of the control class students obtained a mean of 64 with a moderate category while the experimental class obtained an average of 74 with a high category. This shows the influence of glossary media in the material world of plants in SMAN 1 Teluk Kuantan with a significant level of 0.05. Thus, there is an influence of the use of pictorial glossaries on the creative thinking abilities of the control class students with the experimental class on plant material in the learning process.]]>

<![CDATA[This study aims to determine the effect of learning journals with Problem Based Learning (PBL) models on the metacognitive abilities of class X students of SMAN on environmental pollution material. This type of research was quasi-experimental research. The study population was all students of class X SMAN as a hypothetical population. The research sample consisted of 72 students consisting of 36 students in class X MIPA 2 as an experimental class and 36 students in class X MIPA 5 as a control class. Data collection used questionnaires and description problems. Validation used in the form of content validation and empirical validation. The analysis technique used the One Way Anova test analysis. Based on the results of data analysis and discussion show that the use of learning journals with problem based learning models has a very significant effect on students metacognitive abilities in biology learning at SMAN 2 Pekanbaru. The magnitude of the value of the analysis of the average score of the metacognitive abilities of the experimental class in the very good category is 125.53 while in the control class in the good category is 107.43. This shows the metacognitive ability of students who follow the use of learning journals with problem based learning models is better than students who follow conventional learning.]]>

<![CDATA[This study aims to determine the pH variation of the growth of Bacillus cereus strain IMB-11 in degrading diesel fuel. The research was conducted in the Laboratory of PMIPA, FKIP, Universitas Riau while total petroleum hydrocarbon (TPH) was measured in the solid residue in the Laboratory of the Faculty of Civil and Environmental Engineering, ITB. This research was conducted in November 2019 – March 2020. The study was designed in a completely randomized design with 3 treatments and 3 replication groups. The media used are SMSS media with the addition of pH 6.5; pH 7.0; and pH 7.5, which was added with diesel fuel as much as 5% and bacterial isolates of Bacillus cereus strain IMB-11. The test parameter was the optical density (OD) of bacterial growth of Bacillus cereus Strain IMB-11 which was monitored using a spectrophotometer for 6 days and the measurement on the level of degradation or TPH diesel fuel using the Gravimetric method. Based on the research, the moderate pH of 7.0 was the best condition for strain growth with an OD of 5.8 with 26.95% of degradation rate of diesel fuel in vitro.]]>
