Abstract

The purpose of this study was to determine the effectiveness of PBL learning model development effectiveness and results of critical thinking ability to learn science in a small-scale test (10 students) and large-scale test of class VII C totaling 34 students of SMP Negeri 1 Lumajang semester of the 2016-2017 academic year even. Data collection techniques used include Model validation, questionnaire, Observation, and Test.Analisis data used in this study using descriptive quantitative. The results showed that the application of PBL learning model with Takrir can improve the ability of critical thinking and science learning outcomes of students SMP Negeri 1 Lumajang. The average percentage of validation models and learning tools from experts (lecturers) and users 88.9% (Valid). Results increased students' critical thinking skills from questionnaire results and 85% observation and 82% student learning outcomes.

Abstract

This article discusses how high school students' creative learning in Biology learning to improve Communication Skills. Creative learning is learning that puts the teacher forward in facilitating learning activities, so that the learning atmosphere is conducive. Communication Skills is the extent of the use of the mind in solving problems by using its thinking skills at a higher cognitive level. This type of research is development research (Research and Development), which is used as concrete evidence in increasing Communication Skills with creative learning involving 10 schools, both public and private schools, and 10 Biology subject teachers as a needs analysis. Retrieval of need assessment data using a questionnaire technique through Google Form given to high school biology teachers. The results of the need assessment show that teachers who always improve students' creative learning by 70%, implementation of the Problem Solving learning model by 30%. Teachers still have difficulties in implementing Problem Solving learning to improve creative learning by 80%. Conclusion SCICR learning can be used to increase Communication Skills and creative thinking in students. Teachers still have difficulties in implementing Problem Solving learning to improve creative learning by 80%. Conclusion  SCICR learning can be used to increase Communication Skills and creative thinking in students. Teachers still have difficulties in implementing Problem Solving learning to improve creative learning by 80%. Conclusion SCICR learning can be used to increase Communication Skills and creative thinking in students.

Abstract

This study aims to examine the validity of the MORISE learning model. The research design used follows the Education Research and Development method, which involves the development of the model starting from designing the model to implementing it. The validity test of the MORISE model is conducted by two science education faculty members from the Postgraduate Program at UNEJ as expert validators, and one user validator, with the purpose of obtaining feedback and improvements for the learning model developed by the researcher. The first expert validator gave a score of 93%, the second expert validator gave a score of 84%, and the user validator gave a score of 95%. The average result of the final validation is 91%, falling within the highly valid criteria (>81.25%), thus indicating that the MORISE learning model can be used without revisions.

Abstract

Introduction: Dengue hemorrhagic fever (DHF) is an important public health problem in Indonesia because its morbidity and mortality are quite high. Prevention by vector control methods with chemical insecticides adversely affects the environment. Research on granular bioinsectide mixture of betel leaf extract and sugar apple seeds against Aedes aegypti is expected to be used to break the chain of Aedes aegypti mosquitoes starting from the juvenile stage (eggs) as an effort to control the vector population naturally. Objective: This study aims to analyze the effect of granule bioinsecticide mixture of sugar apple seed extract and betel leaf on changes in the morphology of Aedes aegypti eggs. Methods: This study is a true-experimental study with a Post test Only Control Group Design design. The treatment group will be given a granular bioinsecticide, a mixture of sugar apple seed extract and betel leaf, positive control will be given abate while negative control will be given aquades. Each group uses 25 eggs with 3 repetitions. On day 3, all eggs will be observed using a stereo microscope to determine morphological changes. The data obtained will be analyzed using ordinal regression test. Results: the ordinal regression test got the value of ρ in the Wald test between (0.012 - 0.955)> α = 0.01. Conclusion: there is no effect of mixed granules of betel leaf and sugar apple seeds on the mortality of Aedes aegypti eggs. Further research is needed on new formulations using other natural ingredients to increase the effect of ovicides on Aedes aegypti.

Abstract

Colletotrichum  gloeosporioides is  a  disease  which  can  cause  significant yield  loss  of  cocoa.  The  objective  of  this  research  is  to  investigate  the  abilityof  antagonist  microbes,  Trichoderma  harzianum,  Trichoderma  koningii,  Bacillus subtilis  and Pseudomonas  fluorescens  in  controlling  gloeosporioides  biologically  in  laboratorium  condition.  The  experiment  was  carried  out  in  Crop  Protection  Laboratory,  Indonesian  Coffee  and  Cocoa  Research  Institute.  Results of  this  research  showed  that  antagonist  fungi,  T.  harzianum,  T.  koningii,  had  a stronger  ability  in  inhibiting  growth  of  C.  gloeosporioides about  83%  compared  to  the  ability  of  antagonist  bacteria,  B.  subtilis  and P.  fluorescens,  only about  49%. Key words: Growth  inhibition,  Colletotrichum  gloeosporioides,  Trichoderma  harzianum, Trichoderma koningii,  Bacillus subtilis, Pseudomonas fluorescens.
