Fri, 05 Apr 2024 00:00:00 +0000

This research analyzes students' creativity in making posters using the Project-Based Learning (PjBL) Model. This research uses a case study method. A case study is an empirical investigation that investigates a phenomenon in the context of real life. There are four aspects of creativity. First, creativity is defined as a force within the individual. Second, creativity is managing information and using skills and imagination to do or create something. Third, creativity produces something new or a work of art. Fourth, creativity is a product that is produced, for example, ideas, written works, or products. In this case, creativity shows students' ability to develop ideas about HIV and AIDS in poster form and complete posters on time. Poster-making is an assignment that will foster student creativity. In making posters, students will determine essential things about the material included in the poster. Therefore, using the Project-Based Learning (PjBL) model in the assignment to make posters in class X Science at one of the senior high schools in Serang City can initiate student creativity.

Scientific Communication and Student Interest in Biology Learning through Pictorial Riddle Method

Tue, 30 Apr 2024 00:00:00 +0000

Currently, the main challenge in education is to increase student engagement in science learning. Scientific communication skills are critical skills students need. The use of Pictorial Riddle method is a technique, way or effort made in learning to inform scientific facts for students through images, for example presented in the form of posters, pictures on the blackboard, or projections contained in object transparencies. This study aims to explore how the use of Pictorial Riddle learning method can improve students' scientific communication skills and at the same time arouse their interest in science learning. The method used in this research is a case study, using a sample of 57 students of class XI MIPA selected by random sampling technique. The results showed that the Pictorial Riddle learning method has a good effect on students' interest in science learning where students get learning equipped with pictures on the learner worksheet to be analyzed by students. The Pictorial Riddle approach opens space for student creativity, increases active participation, and strengthens understanding of scientific concepts. This can be the basis for innovative learning approaches, namely with a group learning system to develop scientific communication skills and increase student interest in science learning

Sun, 05 May 2024 00:00:00 +0000

The standard of operating procedure (SOP) is a laboratory activity method and must meet the criteria of good laboratory practice (GLP) and other stipulations of valid legislation. The article aims to establish ownership/lack of the SOP of a laboratory that has a public high school laboratory in the city of Yogyakarta. It uses descriptive research. The purpose of descriptive research is to describe images systematically. The research was conducted at Yogyakarta State High School in June 2022—data collection techniques via observation, interviews, and questionnaires. The forms of the instruments used were observation sheets, interview sheets, and checklists, where the instruments had been validated. Samples in this study are random sampling, SMA A, SMA B, and SMA C. This research subject is the head of a high school biology lab in Yogyakarta. The study showed that high school biology LABS A, B, and C already had the SOP implemented, but there was still a lack of it, and this led to increased safety principles. School A has as many as 9 SOPs, school B has as many as 10 SOPs, and school C has as many as 8 SOPs. Out of all three schools, only school B had SOP malfunction of lab equipment. Presumably, school B has the most complete SOP than schools A and C.

Blood transfusions are an important part of medicine for patient recovery. Therefore, the transfused blood must be free from viruses, bacteria, and even parasites that can be transmitted through blood transfusions. Human Immunodeficiency Virus (HIV/AIDS), Hepatitis C, Hepatitis B, and Syphilis are among the illnesses that can be transferred through blood transfusions. This research aims to determine screening parameters for transfusion-transmitted infection using the rapid diagnostic test method. This type of research is experimental with a cross-sectional design. The samples used were ten blood samples, taken intravenously and then centrifuged at a speed of 1300 rpm for 4 minutes. After that, screening is carried out with a rapid diagnostic test. The screening results of the ten blood samples examined were valid and negative or non-reactive for HIV/AIDS, Hepatitis C, Hepatitis B, and Syphilis. These results indicate that the blood samples tested can be categorized as blood samples that passed the screening test or the blood examination test for four parameters of transfusion-transmitted infection.
