Abstract

The image quality improvement process plays a very important role. This is because the process can increase the clarity and accuracy of image detection. One type of image detection that exists is the detection of garbage found under the sea. One of the image quality improvement processes is related to noise removal. Noise is a sudden increase in pixel intensity in an image. This can cause various problems that occur such as in medical photos, satellites, and photography. One method used to remove noise from images is using Adaptive Fuzzy Filter (AFF). This method is carried out by first finding the average value of the mean fuzzy set and the gray level fuzzy. After that, the value comparison process is carried out. From the results of the research conducted on 689 images from the dataset obtained, there is a decrease in the amount of noise of around 96,23% of the total noise obtained previously. This can certainly provide good results in terms of changes in noise that have been made.

Abstract

The role of technology that continues to develop in the era of globalization, especially in the field of education, demands various innovations in the teaching and learning process to improve the quality of learning in the world of education. However, in learning, some students have negative perceptions that can make students not enthusiastic about participating in learning. Students will have difficulty understanding the material and will impact less than optimal learning outcomes of mathematics and physics in learning. This study examines the differences in students' perceptions based on gender in grades A and B in the physics-mathematics e-module. This type of research is quantitative and is conducted by a survey. The data collection instrument is a perception survey using a Likert scale. Data were analyzed descriptively (mean, median, mode, frequency, and percent) and inferential statistics (hypothesis test: normality and homogeneity tests, and hypothesis tests: independent T-test). Technique The sample is a total sample of 80 students from 2 classes. The result of this research is that there is a significant difference between female students' perceptions with a significance level of 0.049 and a significance level of 0.005 for boys. The key is that the average difference in perception between women and men is lower. Men are more rational in inserting something, while women are more emotional. The results of this study are expected to contribute to educators in improving the quality of learning in an educational institution.

Abstract

The halal food study is one of the prominent research fields in halal trends. Currently, the halal food concept is not only the worship of Muslims to Allah, but also this concept is adopted by non-Muslim with healthy lifestyle considerations. Therefore, the insight of the influenced variable on purchased intention behavior of students is crucial to research as basic information for all stakeholders, such as the seller, marketer, policymaker, government, and researchers. This study aims to identify and compare the independent variables that influence the behavior of students' purchase intentions from the school's clustering perspective. A quantitative approach has investigated the influence of attitude and need for cognition (NFC) variables on students' purchase intention behavior on halal food. The self-administrated questionnaire was used to collect the data from 561 respondents and input them into the Survey123 software. The data were analyzed using descriptive and interferential statistics. The result showed that attitude toward halal (HA) and NFC were accepted as the influenced variable on halal food purchase intention behavior. Furthermore, the students from Islamic schools tend to have purchase intentions on halal than in senior high The result of this study could be strategic marketing in the halal food industry. Then, the school must strengthen halal awareness in the syllabus.

Abstract

“Narkoba” is known as an narcotics, psychotropics, and other addictive substances. Drugs are substances that can affect brain function and often cause dependence. One type of drug that is common in Indonesia is marijuana. Marijuana is a psychotropic that contains tetrahydrocannabinol (THC). When THC enters the human body, it will undergo a metabolic process and produce metabolites in the form of 11-nor-δ 9 -tetrahydrocannabinol-9-carboxylic acid (THC-COOH) which are then excreted in the urine. Urine identification can be used to prove someone's use of marijuana. Identification is carried out using urine from the National Narcotics Agency's Narcotics Laboratory Center to confirm the presence of THC-COOH using a Gas Chromatography-Mass Spectrometer (GC-MS). Urine identification is carried out with a preliminary rapid test and a confirmation test using a GC-MS instrument. The identification results showed that the urine was positive for THC-COOH.

Abstract

Local values play a strategic role in shaping the character and identity of students, especially in the context of Vocational High Schools (SMK) which prepare students to enter the workforce while maintaining local cultural roots. In Warungkondang District, Cianjur Regency, the tradition of making tempeh has become part of the community's life which is rich in cultural values such as mutual cooperation, hard work, responsibility, and independence. However, in learning practices at SMK Al Ahmad, this local potential has not been fully integrated into the curriculum, especially in the Arts and Crafts (SBDP) subject. In fact, learning based on local wisdom can strengthen the relevance and meaningfulness of the education process. This study aims to analyze how craft learning by making tempeh can strengthen local values and foster student independence. The study used a qualitative approach with a case study method. The subjects of the study included SBDP teachers and grade X students at SMK Al Ahmad. Data collection techniques were carried out through observation, in-depth interviews, and documentation. Data analysis used the Miles and Huberman model which includes data reduction, data presentation, and drawing conclusions. The results of the study showed that project-based craft learning of making tempeh carried out in a participatory and contextual manner had a positive impact on strengthening students' independent character. Students showed increased ability in planning, making decisions, solving problems, and increasing self-confidence and responsibility. Strengthening local values through the learning process also fosters appreciation for regional culture and strengthens the relationship between schools and communities. Thus, the integration of local wisdom in craft learning is proven to not only enrich students' learning experiences, but also be an effective strategy in character building. This model can be replicated and developed in other contexts as a contribution to contextual, transformative, and sustainable education.

Abstract

Purpose of the study: This study investigates the relationship between students’ attitudes and their motivation to study physics in vocational high schools. Recognizing that physics is often perceived as a difficult subject, this research seeks to understand how affective factors influence student engagement and achievement, particularly in vocational education settings where applied sciences are critical. Methodology: The study employs a quantitative descriptive design with a correlational approach, using validated questionnaires distributed to vocational students. To enrich the quantitative findings, semi-structured interviews were conducted to explore students' perceptions more deeply based on specific indicators of attitude and motivation. Data were analyzed using both descriptive and inferential statistics, particularly Pearson correlation analysis. Main Findings: The results revealed that both students’ attitudes towards physics and their motivation to learn were generally in the “fairly good” category. A positive and significant correlation between the two variables was found, with a moderate Pearson correlation coefficient of 0.622, indicating that students with a more positive attitude tend to have higher motivation levels. This emphasizes the vital role of affective domains in supporting physics learning outcomes. Novelty/Originality of this study: This study introduces a novel integrated analytical framework that merges quantitative correlation data with qualitative insights, providing a deeper understanding of the synergy between attitudes and motivation. Unlike previous research that often examined these factors independently, this study emphasizes their interrelated impact on vocational physics education, offering new directions for designing affective-based learning interventions aimed at improving student cognitive, affective, and psychomotor performance in technical fields.
