Abstract

Government demands the universities as the highest education institution, to compulsory produce quality graduates equipped with good potential and skilful in their respective fields. Thus, the students are expected not only to absorb the course material given, but also are able to apply it creatively. Success or failure of a student in higher education will be influenced by high spirit of life, and strong optimism towards success. Therefore, this study is aimed to investigate the influence of learning media and students’ motivation toward the learning outcome of mathematics education program. Survey is the method chosen for this study with quantitative approach, and 40 students were chosen randomly for solid geometry course in mathematics education program, Universitas Flores. Likert scale was used in the instrument of data collection techniques. Quantitative analysis was used with descriptive statistics, and involved Bivariate (Pearson) Correlation, Classical Assumption Test, and hypothesis testing. The findings show that the learning media (X1) and learning motivation (X2) seen as positive influence on learning outcomes (Y), it can been seen through the correlation analysis from R hiring for X1 against Y for 0.529 and X2 For Y the calculated R value was obtained for 0.732 and the significance value between X1 and X2 for Y abtained two asterisks (**) so that there was positive influence with a significance level of 1%. In other words, the more increase or the better the learning media and students’ motivation are, the more increase and the better the students learning outcome.

Abstract

The Role of mathematics in the development of science and technology in everyday life is increasingly important. Therefore it is necessary to find various strategies to improve students' ability to understand mathematics so that they are able to face the problems faced. In order for mathematics learning to be meaningful then classroom learning must associate mathematical concepts with everyday student experiences. The purpose of this study is to produce learning tools and find out student learning outcomes, the type of experimental research that begins with the development of devices, in this study used descriptive analysis to determine the effectiveness of learning tools and inferential statistical analysis to find out whether student learning outcomes following realistic contextual mathematics learning better than the learning outcomes of students who take conventional learning. The results of descriptive analysis obtained realistic mathematics learning based on effective context. And the results of inferential analysis obtained learning outcomes of students who take realistic mathematics learning is better than the learning outcomes of students who take conventional learning, this can be seen by using a significant level = 5% obtained F (0.95; 2; 67) = 3.13 , means F *> F (0.95; 2; 67), then H0 is rejected. This means that the linear regression model of the experimental class and the control class are different. This shows that contextual based realistic mathematics learning can improve student learning outcomes in class VII of SMP Negeri 2 Ende Selatan

Abstract

The post-disaster evacuation process is something that must be done to minimize casualties. The process of evacuation should get the attention that more than the government and society. Often the process of evacuation was not done with good, so that raises some problems such as the slow evacuation, the buildup of victims in the evacuation route and increasing casualties due to slow handling. In the case of the earthquake, often found some victims do not evacuate and trapped in the rubble. Seeing the fact that, the process of evacuation of victims of the earthquake the Earth needs to be planned by well so that the evacuation can be done with good. The research is discussed about the development model of the evacuation of victims of the disaster earth on building multi-story. The stages of research begin with doing the characterization system. The next stage is the process of developing a mathematical model. After the model is developed, the method of achieving the model solution is further developed. The final stage of this research is the analysis of the model and concluding. The model is produced in the research is expected to result in a solution that is good and right for the evacuation of victims of the disaster earth on building multi-story.

Abstract

Good health and well-being, the third goal of sustainable development goals, are defined as a holistic state of physical, mental, and social well-being as well as the quality of life experiences. The achievement of good health and well-being is individual responsibility and self-reliance at individual, family, and community level which is supported by chemistry, especially food chemistry, literacy. Food chemistry is a multidisciplinary study including organic chemistry, inorganic chemistry, biochemistry, toxicology, nutrition science, as well as agriculture and post-harvest processing science. People can access the proper chemistry literacy formally through education in schools and universities, or informally through being actively participated in a community-based program such as Family Welfare Coaching (ibu PKK), Youth Club (Karang Taruna), and recreational sports organizations under the coordination of the Ministry of Youth and Sports (Menpora). This scientific article discusses the connection between chemistry literacy and consumption of nutritious, diverse, and balance (NUDIBA) food in the context of achieving good health and well-being based on kinds of literature review. The aim is to propose the synergic collaboration working between academics of chemistry and related sciences in a community service program based on empowerment which is related to health care towards the quality and sustainable Indonesian human resources. At the end of the discussion, this article will conclude that chemistry literacy within the consumption of NUDIBA food can control the extreme demand on one such of food commodity and lead the community’s behavior on biodiversity conservation.

Abstract

The ability to solve mathematical problems is an important part of learning mathematics that links daily life. The importance of having good mathematical problem solving skills, so understanding mathematics is also good, especially on the pythagoras theorem material. Material related to the construction of this triangle can be applied in calculations in real life. To be able to construct the concept of the pythagoras theorem problem, it needs an ability that can represent imagination into an object, this ability is called spatial visualization ability. This research will discuss the students' mathematical problem solving abilities on the pythagoras theorem material based on the spatial visualization abilities possessed by students. The research method used was a qualitative research with a descriptive approach to students of class VIII MTS 38 Jakarta. The test instrument was a matter of pythagoras theorem description and spatial visualization intelligence test. The results showed that students who have low spatial visualization skills tend not to be able to solve problem solving problems well, students who have moderate problem solving abilities can solve problem solving problems even though there are still steps that are not right, while students who have high spatial visualization abilities can solve problem solving problems with the right steps and answers.

Abstract

This study aims to analyze the differences in learning outcomes between students who study with creative problem-solving learning models and students who study with conventional learning models. This type of research is a quasi-experimental research design with a way of pretest-posttest nonequivalent control group design. The population of this research is all students of class VIII of SMP Negeri 3 Seririt in 2018/2019 academic year consisting of 230 students. Class samples were taken by group random sampling technique. Student learning outcomes data were collected by learning outcomes tests which were analyzed descriptively and ANAKOVA, with hypothesis testing performed at a significance level of 0.05. The results showed there were differences in learning outcomes between students who studied with creative problem-solving learning models and students who learned with conventional learning models. Learning outcomes of students who learn with creative problem-solving learning models are at high qualifications (M = 73.00; SD = 8.30). Learning outcomes of students who learn using conventional learning models are at low qualifications (M = 52.00; SD = 7.60). LSD test results show that the learning outcomes of students who learn with creative problem-solving learning models are higher than conventional learning models (F=10,320; p<0,05).

Abstract

Crab is one of the commodities exported by Indonesia in the fisheries sector. Crab processing to be exported produces crab waste. Crab shells contain high calcium carbonate. With a large CaCO3 content, crab shells can be used as a precursor of CaO in hydroxyapatite synthesis. CaO can be obtained by calcining calcium carbonate contained in the crab shell waste content. The calcination process is the process of decomposition of calcium carbonate (CaCO3) compounds into calcium oxide compounds (CaO) through heating at high temperatures. In this study the calcination temperature used was 1000 oC while the calcination time was varied ie 6 hours and 10 hours. The results showed that the crab shell, which is a source of CaCO3, which was calcined at 1000 oC for 6 hours and 10 hours both produced CaO compounds. CaO compounds produced have a crystalline form and are not in the form of amorphous. This can be observed from the XRD diffraction pattern, which is seen many peaks with varying intensity values. The second crystal system of the sample is cubic. There was no significant difference in the pattern of XRD calcination results of 6 hours and 10 hours, the difference only lies in the value of the variation in intensity of the peaks that formed. So it can be concluded that calcination at a temperature of 1000 oC with a length of 6 hours and 10 hours produces CaO crystals with a crystal size at a maximum peak is around 10 A.
