Abstract

This research examines zeolite-Y made from sidrap clay and rice husk ash as the adsorption of copper (Cu) and lead (Pb) metals. The method used is hydrothermal, using an autoclave with variations of Pb and Cu metals, namely 200, 400, and 600 ppm. The results showed that zeolite-Y was able to adsorb Cu and Pb well, as evidenced by the presence of Pb and Cu in the mapping results and EDS (Energy Dispersive X-Ray) and SEM (Scanning Electron Microscopy) showed the morphology of each sample of Cu and Pb metals. Pores indicate the absorption of Cu and Pb metals in the zeolite. The results of AAS (Atomic Absorption Spectrophotometer) show that the greater the levels of Cu and Pb produced, the greater the absorbent level.

Abstract

Radiation exposure to the ovaries due to abdominal radiology is unavoidable given its location in the lower abdomen. Ovaries are organs that have a high level of sensitivity to radiation. One of the efforts used in the application of radiation protection optimization is the use of the 10 kV rule method. This study aimed to determine the estimated reception of ovarian radiation dose on abdominal radiology examination. The examination was carried out by anteroposterior (AP) projection of the female body phantom (FAX06) using Caldose_X software. The beam variation is set from 60kV/32mAs to 100kV/2mAs. The results of the ovarian radiation dose examination were: 0.484mGy for 60kV/32mAs, 0.402mGy for 70kV/16mAs, 0.309mGy for 80kV/8mAs, 0.227mGy for 90kV/4mAs, and 0.154mGy for 100kV/2mAs. When compared with the radiation dose limit for the abdominal examination set by BAPETEN, the data for this study were much smaller. Likewise, when compared with the reference results of previous studies, the data on ovarian radiation dose reception in this study were still within safe limits.

Abstract

Conceptual understanding is significant aspect in Physics Education. Student’s understanding on particular content stands as the significant foundation to build holistic comprehension. The Program for International Student Assessment (PISA) coined students’ ability to understand scientific reading as part of scientific literacy. The role of reading activity in science is fundamental as the position of the experiment. It means reading not only facilitates students to master scientific information but also assists them in having problem-solving skills. This work promotes reading activities to structure students’ comprehension. Anticipation guides facilitates students for having empirical competencies, such as applying, analyzing, and evaluating. These competencies improve students’ conceptual understanding.

Abstract

This research is motivated by the low level of competence of graduates from universities which results in low professionalism in the world of work in the current era of globalization. The purpose of this research is to show the relationship of increasing professional competence through blended learning model. The sample of this study was forty-five students majoring in Mining ISTP FY 2021/2022 who were made into two sample groups. The control group (CG) of 20 students was the group that was not treated with the blended learning model, while the experimental group (EG) of 25 students was treated with the blended learning model. This research was conducted using a quantitative descriptive method. To determine the level of professional competence of students, a test is used for each competency criterion. The results obtained at the level of competence in the cognitive control group 0%, andragogical competence 25% and social competence 35%, and in the experimental group cognitive 48%, andragogical competence 72% and social competence 64%. The results of this study concluded that the blended learning model can improve and develop the professional competence of graduate students so that they are competent in the world of work in the era of globalization.
