Abstract

Learning difficulties are conditions where students experience difficulties in understanding subject matter, so that the learning outcomes obtained do not match their abilities. This study aims to determine the factors causing learning difficulties in Natural and Social Sciences (IPAS) for fourth-grade students at SDN 40 Cakranegara. Data collection methods were carried out using questionnaires and interviews. The data analysis technique used was Miles and Huberman with analysis components including data reduction, data presentation, and conclusion drawing. The results showed that learning difficulties in IPAS are influenced by internal and external factors. Based on the questionnaire results, the contribution of internal factors includes learning attitude (15.70%), motivation (23.24%), and interest (21.66%), while external factors consist of family (22.74%) and school (17.03%). In detail, from internal factors, students' learning attitudes are still low, especially in the indicators of self-confidence and feelings; learning interest is low in the indicators of attraction and feeling of pleasure; and motivation is not yet optimal in the indicators of initiative and commitment. From external factors, the school's social environment is not fully supportive because students lack encouragement from peers, while from the family side, an unsupportive home atmosphere, unsupportive parenting styles, and economic limitations were found. The learning difficulties in IPAS among fourth-grade students are the result of the interaction between weak internal factors and lack of external support, thus requiring synergy between teachers, schools, and parents to help students overcome learning difficulties more optimally.

Abstract

This study aims to improve the inference time and accuracy of ship detection in complex maritime imagery using the DC-YOLOv8 algorithm. DC-YOLOv8 is an enhanced version of YOLOv8 specifically designed for real-time detection under challenging visual conditions, such as low lighting, fog, and dynamic sea backgrounds. The method integrates an MDC module, depthwise separable convolution, and an updated feature fusion strategy. The evaluation was conducted using the SeaShips dataset and compared with the baseline YOLOv8 model. Experimental results show that DC-YOLOv8 achieves a significant improvement in inference time, reducing it by 2.855 ms, while maintaining a competitive mAP score of 0.7953. These results indicate that DC-YOLOv8 is more effective for real-time detection tasks in maritime environments.

Abstract

The advantages of mobile or portable CXR in Covid-19 patients are minimal radiation received compared to CT SCAN, as well as monitoring or evaluating patient diagnoses in the Intensive Care Unit (ICU). CXR in the Anterior Posterior (AP) projection with Covid-19 patients lying supine or sitting in the ICU are usually uncooperative in adjusting the patient's position, resulting in low image quality, thus requiring Digital Imaging (DIP) in an effort to improve image quality. This study used DIP Contrast Limited Adaptive Histogram Equalization (CLAHE) on images of Covid-19 patients in the ICU, and compared pre and post CLAHE on quality and pathological information

Abstract

This study was motivated by the low understanding of seventh-grade students regarding the topic of cells. The abstract and microscopic nature of cell concepts often makes them difficult to visualize, resulting in learning that tends to rely on memorization. This research is a classroom action research aimed at improving the learning outcomes of 32 seventh-grade students at SMPIT Nur Hidayah. The research activities consisted of a pre-cycle, Cycle I, and Cycle II. In the pre-cycle, learning was conducted using lecture and discussion methods; in Cycle I, the Project-Based Learning model was implemented with a microscope project; and in Cycle II, a plastiline project was applied. Data were collected through observation, learning outcome tests, and questionnaires. The collected data were analyzed using quantitative and qualitative descriptive analysis, with success indicators set at an average score of 80, a minimum of 80% classical mastery, and an N-gain categorized at least as medium. The results showed that in the pre-cycle, the average score was 51.91 with 3.13% classical mastery. In Cycle I, the average score increased to 60.09 with 15.63% classical mastery, and in Cycle II it further increased to 84.06 with 93.75% classical mastery. The N-gain from the pre-cycle to Cycle I was 0.22 (low), and from Cycle I to Cycle II was 0.58 (medium). Thus, the success indicators were achieved, and it can be concluded that the classroom action using the Project-Based Learning model with the Mikroplas media successfully improved student learning outcomes
