Abstract

The research aims to reveal the influence of the Problem Based Learning (PBL) model on students' critical thinking ability in optical instrument material. This research is a quasi-experimental research with Pre-test and Post-test Design. The subjects of this study were class X MAN 3 Malang. The experimental and control classes received PBL models and conventional learning models respectively. The instrument of this study was the Optical Instrument Critical Thinking Ability Test in the form of 14 essay questions with Cronbach’s alpha reliability 0.78. The research data were analyzed using several tests including t-test, N-gain, and size effect tests. Based on the results of the analysis, it was shown that the implementation of the PBL model succeeded in increasing students' critical thinking ability higher than that of conventional learning. The experimental class was able to reach the high N-gain score category, while the control class was in the medium category. The research has a “large” size effect category. This means that the PBL model implemented has a stronger influence than that of conventional learning in improving students' critical thinking ability. Thus, the PBL model can be recommended as an alternative learning model in improving students' critical thinking ability in physics learning on the topic of optical instruments.Penelitian bertujuan untuk mengungkap pengaruh model Problem Based Learning (PBL) terhadap kemampuan berpikir kritis siswa pada materi alat optik.

Abstract

Experiments are needed in science learning. However, the instruments used cost high; thus, it is difficult to find, especially in rural areas. The purpose of this study was to develop a low-cost tool for science learning. This science experiment has been successfully developed from inexpensive common materials. Research and Development design employing Gall and Borg Model was used in developing the science instruments. Analysis, design, fabricate, validate, revising, and implementation were the steps in producing the devices. Observation sheet and questionnaire were used for evaluating and validating the instrument. The subject of this study was students of SMPN 1 Sigi, Sigi Sub Province, Central Sulawesi.  After designed and fabricated, the devices were validated by two judges to know the practicality and convenience. The tools were set up to demonstrate the expansion concept of gas and liquid; also, to establish the presence of hydrostatic pressure inside the fluid. The N-gain analysis was performed to know the increase of student understanding after employing the instruments in science learning. The results showed that student understanding was increased by about 30.13% after using devices in science learning. In other words, the designed tools were succeeded in introducing the concept of gas and liquid well and in establishing the fact that the higher hydrostatic pressure of the fluid is discovered in a deeper location inside the liquid. Based on the success, the devices were socialized to other science teachers in the area.

Abstract

Meat refers to parts of an animal's body, such as liver, kidneys, brain, and other muscle tissues that are edible, and meat has a fairly complete nutritional content. Meatballs are a type of food popular in Indonesia, but are prone to spoilage due to the activity of microorganisms. The production of beef meatballs with the addition of moringa leaf powder (Moringa oleifera) can inhibit microbial growth and affect the quality of beef meatballs. This study aims to evaluate the effect of Moringa oleifera (Moringa leaf flour, MLF) addition on total microbes and organoleptic of beef meatballs, including color, texture, taste, and preference for color, aroma/smell, texture, and flavor. The research method used a completely randomized design (CRD) with four treatments: meatballs without the addition of MLF (T0) and meatballs with the addition of MLF 1% (T1), 2% (T2), and 3% (T3). The parameters observed included measurements, total microbes, and organoleptic characteristics, which included hedonic and sensory quality tests of beef meatballs. The results showed that the addition of moringa flour had a significant effect (P<0.05) on the results of hedonic and organoleptic quality tests but had no significant effect (P>0.05) on total microbes. The study results show that adding MLF at different levels does not effectively suppress the microbial growth of beef meatballs. Adding MLF with different levels in beef meatballs does not effectively suppress microbial growth. The addition of MLF in the hedonic and organoleptic quality tests significantly affected color, texture, smell, and taste, and was still acceptable to the panelists.

Abstract

This study aims to analyze the impact of social media on the training patterns and motivation of amateur athletes in the digital era. The digital era has transformed various aspects of human life, including sports. Social media has now become a platform used not only for social interaction but also as a source of information, inspiration, and motivation for amateur athletes in their training programs. This study used qualitative methods with a phenomenological approach, involving 30 amateur athletes from various sports in the Jakarta area and its surroundings. Data were collected through in-depth interviews, participant observation, and analysis of respondents' social media content. The results indicate that social media has a significant impact on amateur athletes' training patterns, both positively and negatively. Positive impacts include increased motivation through inspirational content, broader access to information on training techniques, and the formation of a supportive virtual community. However, negative impacts were also found, including psychological stress due to social comparison, the spread of inaccurate information, and the potential for addiction to social validation. This study concludes that social media use needs to be managed wisely to provide optimal benefits for amateur athletes' development without causing detrimental negative impacts.
