Abstract

This research aims to know the influence of guided inquiry learning with flash based Invertebramedia on the learning outcome of senior high school students. The research was done in SMA N 1 Pamotan using Quasi Experimental Design. The sample of the study was X MIPA 1 class (experimental group) and X MIPA 2 class (control group) which was taken by purposive sampling technique. The results showed that there were increasing of cognitive’s learning outcome of the experiment group was 80% and control group was 34.2%. There was a significant difference in the average of cognitive learning outcomes of the experimental group and control group. Analysis of affective and psychomotor aspects showed that learning outcome the experimental group higher that the control group. So, the activity of students during learning process was enchancement. The average of the student’s questionnaire responses after joining the learning was 84.9% in good criteria. The teacher and the students also gave good responses on the implementation of the learning in general. The conclusion of the research is the application of guided inquiry learning with Invertebramedia based on flash influence on high school student’s learning outcomes.

Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan efektivitas aktivitas antioksidan antara madu randu (Ceiba petandra) dan madu kelengkeng (Nephelium longanum) dalam memperbaiki profil lipid darah dan MDA serum darah tikus hiperlipidemik. Tiga kelompok perlakuan masing-masing 5 ulangan diperlakukan sebagai berikut kelompok I : kontrol negatif, II: diberi madu randu dan III diberi madu kelengkeng masing-masing dengan dosis 10 ml/kg BB tikus dilarutkan dalam 5 ml air /hari, Madu diberikan selama 15 hari, pada hari ke 16 diukur profil lipid darahnya meliputi kolesterol, trigliserida, LDL, HDL dan MDA. Hasilnya dianalisis dengan anava satu jalan dan bila berbeda signifikan dilanjutkan dengan uji beda Duncan Multiple Range Test. Hasil penelitian menunjukkan kelompok kontrol dan perlakuan berbeda signifikan. Hasil uji lanjut menunjukkan tidak terdapat perbedaan efektivitas aktivitas antioksidan antara madu randu dan madu kelengkeng dalam memperbaiki profil lipid darah namun madu randu lebih efektif menurunkan MDA dibandingkan madu kelengkeng.Mekanisme antioksidasi pada madu terjadi dengan menghambat proses peroksidasi lipid.

Abstract

This Study aimed to determine the effect of guided inquiry-based learning model with Natural Environment Exploration (JAS) approach on the topic of sensory system on student?s Sciencetific Process Skills (SPS) as well as determining the increase of students? SPS. The type of this study was quasi-experimental with non-equivalent control group design. Subjects in this study were students from grade XI of class MIA 4 as the control and XI MIA 5 as the treatment group. The independent variable was the guided inquiry-based learning model with JAS approach on the topic of sensory system, while the dependent variable was students? SPS. Students? SPS was measured by pre-test and post-test consist of 30 questions. The result of data analysis showed that the guided inquiry-based learning model with JAS approach had a significant effect on students? SPS, with the value of determination coefficient at 0.374. Students? SPS increased after the treatment with the average N-gain of treatment group at 0.27. The result of the study concludes that the implementation of guided inquiry-based learning model by JAS approach on the topic of sensory system affects and increases the students? SPS, especially in the aspect of interpreting data, communicating, designing experiment, formulating hypotheses and classifying

Abstract

Lack of drug hazard knowledge becomes one of the drug abuse causes. Drug knowledge (psychotropic-addictive substances) will foster a negative attitude such as a rejection reaction towards drug abuse. Such attitudes may prevent or address drug abuse problems. That prevention needs to be done as early as possible by providing knowledge about drugs trough the school educations. This study would find the relationship between addictive and psychotropic substance knowledge with the attitude on drug abuse and how much that constriction in JHS  students' attitudes. This research method is a survey method with an analytical observational design. The population in this study was all junior high school students in the Semarang North District with five classes (grade IX) as samples taken from three schools in the sub-district. The data collection measuring instruments used in this study is questionnaires and interviews. The results of this study show that more than 50% of students have high knowledge of psychotropic and addictive substances and have a negative attitude towards drug abuse. Data analysis results are obtained by a correlation coefficient value (r) of 0.971 and a coefficient of determination (R2) of 0.942. The R value indicates a positive correlation while the R2 value is how much constricting it is. Based on the results of the study, concluded that the knowledge of psychotropic-addictive substances with the rejection attitudes of drug abuse has a positive and very strong relationship. And as much as 94.2% of the psychotropic addictive substance knowledge is constricting in the formation of students ' attitudes towards drug abuse.

Abstract

The achievement of student learning outcomes is influenced by various factors, such as learning resources and ways of learning. The purpose of this study is to determine the relationship between learning resources and learning outcomes; know the relationship between how to learn and the learning outcomes; and know the relationship between learning resources and ways of learning on the learning outcomes. The sample in this study was 108 students. The independent variables in this study are learning resources (X1) and ways of learning (X2). The dependent variable in this study is learning outcomes (Y). The data collection method used a questionnaire and documentation. Data analysis in this study used descriptive percentages, multiple linear regression, t test and F test. The results showed that the analysis of multiple linear regression obtained equation: Y = 52.078 + 0.224X1 + 0.203X2. Partially, the influence of learning resources on learning outcomes was 43.3%, while the influence of learning methods was 42.6%. Simultaneously, learning resources and ways of learning influenced the learning outcomes by 47.3%, with SE (X1) = 24.6%, and SE (X2) = 22.7%. Based on the results of the analysis, it can be concluded that learning resources and ways of learning significantly influenced learning outcomes, both partially and simultaneously. In this study, learning resources had a greater influence on learning outcomes compared to the of way of learning on learning outcomes. Thus, schools need to optimize all learning resources both in their existence and utilization, and students need to improve their way of learning in order to get optimal learning outcomes.
