Abstract

There have been many assessment instruments developed to measure student science literacy. However, literacy measurement instruments that pay attention to various intelligences and are reflected in the context of multiple representations have not been developed much. On the other hand, it is important to give every student the opportunity to succeed at his intelligence level. This study aims to determine the feasibility of a multi-representation based scientific literacy assessment instrument for high school physics on rectilinear motion concept as well as to describe students' scientific literacy skills and the mastery pattern of the rectilinear motion concept measured by the instrument developed. This research is a Research & Development (R&D) research. The test subjects were 262 high school students who had studied rectilinear motion concept in public high schools with A-accreditation. Data analysis conducted were validity test of instruments by experts; empirical test to obtain validity, reliability, difficulty level, and item difference; student responses to test offerings; profile of scientific literacy skills; and the pattern of mastery of the rectilinear motion concept. From the measurement results, it is evident that the profile of the average scientific literacy ability of high school students is still in the unsatisfactory category. The pattern of mastery of the concept of straight motion based on the modes of representation ranging from the most difficult to the easier ones is graphical, pictorial, verbal, and mathematical representations. This data could indicate that learning by practicing literacy skills still can be improved.

Abstract

This research aims to describe students learning activities through the implementation of students worksheets based on POE. This study was descriptive qualitative research. The research was conducted in one of the Islamic Senior High School in Bantul, Yogyakarta on Circular Motion material. The research subject was determined through random sampling. The number of subjects in this research consisted of 26 students in the first year. Data were collected using an observation sheet in 3 meetings observed by two persons and the interview. The results of the analysis obtained are expressed in terms of percentages and then interpreted in the form of scientific narratives. Data analysis results show that the students’ worksheet based on POE can be used to enhance students’ learning activities, especially in visual activities, oral activities, writing activities, motor activities, and mental activities with the most dominant activities is writing activities, and the weakest one is oral activities. Students feel that using students’ worksheets based on predict-observe-explain makes them involved directly in the demonstration or the practicum, can create their curiosity, make they even more seriously in the study, increase the interest in studying physics and help each other with their friends. But, the students’ confidence and speaking ability must be the concern, so students are not reluctant to share their idea in front of the class.

Abstract

Remote learning has reformed the normal tradition of physics instruction in the existence of COVID-19 pandemic. The previous documentation of student’s misconception is mostly discovered in the normal condition of physics instruction. Regarding to the pandemic outbreak is necessary since distance learning routines have absolutely influence the physics education outcomes all over the world. To explore the issues, this quantitative study has descriptively identified students' misconception on projectile motion in the frame of graphic and figural representations. The six items of Busyairi and Zuhdi’s three tier test were administered to the 76 students in a Javanese public high school, Indonesia. Overall, the Arslan, Cigdemolu, & Moseley’s categorical framework classified that the whole participants still congregate in the misconception’s groups on projectile motion. The lack of students’ representation on projectile motion might be magnified by the pandemic restrictions in providing appropriate visualization on projectile concept. Finally, the author suggested that the alternative of online learning during the outbreak have not yet been effectively engaged to promote the physics representation on projectile motion.

Abstract

The presence of surface water is always being a primary issue in Gunung Kidul regency. An aquifer investigation would support groundwater exploration. The research area is located in Tambakromo village, Ponjong subdistrict, Gunung Kidul Regency, Daerah Istimewa Yogyakarta Province. The aim of this research is about geological and subsurface conditions based on geological data and geoelectrical resistivity methods. By resistivity value interpretation, the position, depth, and thickness of aquifer could be determined. The purpose of this research is to identification of geological conditions that supported being aquifer rock. The method in this research is used geological mapping combined with petrographic analysis. The geophysics method is used to identification of aquifer in research area. Three locations were selected to acquisition geoelectrical resistivity survey. In Grogol village, there is no aquifer based on resistivity values of more than 10000 ohmmeters (andesitic breccia). An akuifuge is interpreted there in andesitic breccia instead of the presence of aquifer. The tuffaceous is interpreted as lapillistone that contained the glass with resistivity value of 43.63 and 340.11 ohmmeters. The Garon and Sumberejo village have aquifer at depth of 50 to 80 meters with a thickness of 13 to 70 meters. The type of aquifer in both area is included an unconfined aquifer, specifically located in between the limestone rock layer and andesitic breccia. By regional stratigraphic correlation, tuffaceous lapillistone is interpreted as derived from Semilir Formation. In addition, the presence of aquifer in research area could recommend for local people and government to reduce the drought disaster.

Abstract

This study aimed to determine the correlation of science process skills with students' creativity in learning of creative problem solving model with an inquiry approach on the simple harmonic motion. The study method that was used is a correlation study between science process skills with students' creativity. The sample was chosen by using the purposive sampling technique that total of 34 students in X MIA5 grade of the academic year 2016/2017 in one of the senior high schools in Semarang. The data collection was conducted by using a science process skills test and creativity test in essay form on the simple harmonic motion. Data were analyzed through correlation test by Pearson Product Moment technique and t-test. The results showed the value of r is 0.332 with low category and the value of tcount is 1.992 lower than ttable is 2.042 with a significance level of 5% and df is 32. This indicated that there was no significant correlation between science process skills with students’ creativity in learning of creative problem-solving model with an inquiry approach on the simple harmonic motion. This meant that students with high science process skills do not always show high creativity too in learning of creative problem-solving model with an inquiry approach on the simple harmonic motion.

Abstract

The widespread use of radioactivity has culminated in adverse health consequences and has generated an entire health science study. It is established practice that certain precautions must be taken to avoid potential exposure to ionizing radiation like an x-ray. One way to control radiation hazards external is to use a radiation shield. In this study, clay-originated bricks were used as a shield and determine its linear attenuation coefficient of x-ray radiation. The bricks were collected from 5 regencies in Central Java province. Digital fluoroscopy was used as an x-ray radiation source and operated in 81 kV 32 mAs; also, it associated with the multi-purpose detector. It shows that linear attenuation coefficient of Boyolali, Klaten, Magelang, Temanggung, and Semarang bricks respectively are 0.8896 cm-1; 0.7455 cm-1; 0.7115 cm-1; 0.7254 cm-1; and 0.7972 cm-1. Furthermore, we calculate the half-value layer of each brick and indicates that brick from Boyolali is the most effective as a shielding among others that can reduce half value of x-ray radiation dose. This research is expected to enhance the systems integration of radiation shielding safeties and allow for the effective treatment of radiation sources for both humans and the environment.
