Abstract

This study aims to determine the effect of concentrations and salinity of seawater on the bioaccumulation of zinc and cesium in the Glauconomya virens. Salinity conditions and contaminant concentrations in the marine environment can change due to weather and other inputs.  A biokinetic experiment was carried out using a single compartment approach that used radiotracer 65Zn and 137Cs.  The experiments conducted were biota collection, acclimatization, bioaccumulation, and elimination. Acclimatization aims for the adaptation of biota in an experimental environment. Bioaccumulation was by placing the biota in an aquarium containing seawater media spiked by  65Zn, Zn, and 137Cs radiotracer contaminants. The elimination process was the release of contaminants from the body of the biota by placing them in clean and flowing seawater. The experimental results show that the uptake and elimination of Zn and Cs were influenced by these two parameters (water concentration and salinity). The highest value of Concentration Factor (CF) for Zn was 11.14 ml.g-1 under influences its concentration of  0.7 ppm in water.  In the depuration process, Zn maintained by G virens were  39.44; 31.17; 23.62; and 23.92% after these organisms accumulate this element from seawater containing 0.1; 0.3, 0.5, and 0.7 ppm, respectively. The highest of 137Cs  under influences its concentration of 3 Bg.ml-1 reached 2.65 mL.g-1. The effect of salinity is directly proportional to the factor value of Zn and 137Cs concentration.

Abstract

Physics learning in SMA N 2 Padang was implemented through theory and practicum for verifying the theories. The results of the initial survey showed that the physics teachers had not yet applied the research-based learning. Supporting facilities such as physics lab and its equipment has been already available, but it has not been utilized optimally. Research-based learning is a model that can improve scientific processing skills and learning outcomes of students. The research aimed to produce a valid, practical, and effective research-based physics learning model and devices. This research was a research and development using the 4D model of Thiagarajan. The instrument of this research are interview guides, observation sheets, sheet of validation of model and learning tools, questionnaire for both teachers’ and learners’ responses, assessment sheets for scientific processing skills, and achievement test. The results showed that the developed model and the learning devices according to the assessment of experts were declared valid. Model and learning devices were practical based on the observation and the questionnaires. The application of research-based physics learning could effectively improve scientific skills and learning outcomes of students. This model is suggested to physics teachers in high school in regard with implementing research-based learning.

Abstract

Food security behavior is essential to be developed through continuous development of knowledge, awareness, attitudes, values, skills, and responsibility. Utilization of system dynamics methodology in educational research in the field of food security is still limited. Thus, this research aimed to develop a model of food security behavior through environmental-based learning by utilizing a system dynamics methodology. This approach starts with defining problems dynamically, developing concepts in circular causality, identifying stocks, flows, simulating, and validating the model. Through quantification of variables involved in the development of food security behavior model, the results showed that during 6 years of simulation, environmental-based learning could improve food security behavior sustainably (from 10.60 at the beginning to 74.19 at the end of simulation year) having the growth forming an exponential curve. The increase of food security behavior occurred gradually through increasing food security attitudes (from 2.09 to 7.45), food security awareness (from 0.55 to 2.34), food security values (from 0.23 to 0.85), food security knowledge (from 1.53 to 6.17), food security skills (from 0.61 to 1.83), and food security responsibility (from 0.88 to 1.67).

Abstract

The increasing of pesticide use is in line with the increasing number of pest populations. However, the use of pesticides causes various negative impacts on the environment (soil, water, and air) such as pesticide-resistant pests, perishing of useful insects which are non-target pesticides, and the use of pesticide which can even lead to poisoning and death in humans. One of the environmentally-safe techniques to control pests is chemical, by the use soursop leaf extract. This study aims to determine the most effective concentration of soursop leaf extract (Annona muricata) in controlling leaf caterpillar (Plutella xylostella) in delima rose apples. The research was carried out in the plantation area of rose apples in tempuran village, Demak. The research method employed experimental research. The study was conducted using Completely Randomized Design. The data were obtained using probit analysis of LC50. The most effective concentration of soursop extract (Annona muricata) on leaf caterpillars’ mortality was 75 ppm. Soursop leaf extract (Annona muricata) has been proven to influence rose apples leaf caterpillars’ mortality index. The LC50 value of soursop leaf extract was 75,16 mg/L. The result showed that soursop leaf extract (Annona muricata) is effective as a biopesticide material to control leaf caterpillar pest for delima rose apples.

Abstract

This study aimed to develop a two-tier multiple choice test about the concept of “light and optical instruments” in 8th grade of Indonesian science curriculum. The test development procedure had three general steps: defining the content area of the test, identification on students’ conceptions, and the development of two-tier multiple choice test. The final version of two-tier multiple choice test consisted of 25 items question. This test was administered to 95 junior high school students. The students had completed a unit on light and optical instruments. The reliability of the test was 0.76. Based on the data analysis, twenty-two alternative conceptions were identified. The results of the study showed that the two-tier multiple choice test was effective in determining the students’ misconceptions and also it might be used as an alternative to the traditional multiple choice test. In conclusion, two-tier multiple choice test can be used to assess students’ conceptual understanding as well as students’ misconceptions on light and optical instruments concept.

Abstract

The aim of this research was to determine the attitude towards scientific research in undergraduate university students from Peru and Spain. The research was descriptive, comparative and cross-sectional. The sample consisted of 953 undergraduate students currently enrolled in universities in Spain (485) and Peru (468), and the information was collected through convenience sampling. The General Index of Attitude towards Research instrument was applied, which was adapted for the study. Its statistical validation was carried out and high reliability of the instrument was proved with a Cronbach's Alpha of 921. According to the questionnaire scores, a sociodemographic survey was also applied. Regarding the results, it was found that students from Peru have a high predisposition towards research (51.5%) compared to students from Spain (23.5%). Regarding knowledge about research, students in both countries recognize that scientific research is not adequately valued (60.6% in Spain and 54.3% in Peru); however, they would like to carry out educational scientific research (63.3% and 71.2, respectively). Regarding the evaluation of the quality of university education, undergraduate students from Spain perceive a better quality in their education (7.22 out of 10), quality of the program in which they are enrolled (7.31 out of 10), quality of fellow students (7.46 out of 10), and welfare and infrastructure services (7.30 out of 10). It is concluded that students from Peru show a better attitude towards research (M=28.98, DT=10.26) than students from Spain (M=22.61, DT=8.28).
