Abstract

Child neglect is a form of emotional violence that can have a significant impact on a child's social and emotional development. Neglect, which is characterized by a lack of attention, affection and support from parents or primary caregivers, often hinders children's ability to build interpersonal relationships, manage emotions and form self-confidence. This impact is not only short-term but also affects the child's life in adulthood, including the risk of mental disorders such as anxiety and depression. This article aims to analyze the impact of neglect on children's social and emotional development and provide recommendations for preventive and intervention steps to support children's optimal growth and development.

Abstract

Indonesia is an agricultural country with great potential in the agricultural sector, both as a source of livelihood and as an economic driver. This sector has an important function in food security, improving farmers' welfare, and preserving the environment. Given Indonesia's regional diversity, it is important to develop policies that suit the agricultural characteristics of each region. This research uses the clustering method, a technique that groups data based on similar characteristics so that objects in one group (cluster) have high similarities, while between clusters they are different. This research applies the clustering method to group provinces in Indonesia based on agricultural sector factors in 2023, using hierarchical and non-hierarchical techniques. The results show that the optimum clusters obtained using both single linkage and K-Means formed five optimal clusters. The Java Island cluster shows high productivity, while Riau, East Kalimantan and North Kalimantan have quite high productivity with minimal labor. The largest clusters have a lot of unmanaged land, increasing employment opportunities. Significant variables influence grouping.

Abstract

This study aims to analyze the intuitive thinking skills of junior high school students in solving geometric problems based on their learning styles: visual, auditory, and kinesthetic. The research employed a descriptive method with a qualitative approach. Data were collected through a learning style questionnaire to categorize students, problem-solving tests on geometric shapes, and in-depth interviews to explore students' intuitive thinking abilities. The findings indicate that students with a visual learning style exhibit stronger intuitive thinking skills compared to those with auditory and kinesthetic learning styles. Visual learners provided clear and well-structured answers aligned with intuitive thinking indicators such as Catalytic Inference, Power of Synthesis, and Common Sense. Conversely, auditory learners tended to give less detailed answers, although they could identify relevant information. Kinesthetic learners offered brief and less detailed responses, particularly in specifying measurements and units in their calculations. These findings underscore the importance of understanding students' diverse learning styles to optimize mathematics teaching strategies, particularly in enhancing problem-solving skills and intuitive thinking.

Abstract

This study aims to analyze the influence of soil contour types and depths on soil characteristics using a Randomized Block Design (RBD) method. The research data were obtained from a secondary dataset encompassing physical and chemical soil characteristics across three contour types (Top, Slope, and Depression) and four depth levels (0-10 cm, 10-30 cm, 30-60 cm, and 60-90 cm). The analysis results indicate that soil contour types and depths do not significantly affect most soil characteristics, such as pH, nitrogen content, phosphorus, calcium, sodium, and soil conductivity. However, significant effects were observed on magnesium (Mg) and potassium (K) content. Conversely, area grouping showed significant effects on nearly all tested soil characteristics. These findings highlight the importance of considering geographical variations in soil management to enhance the efficiency and sustainability of agricultural practices. Further research is recommended to explore other factors affecting soil characteristics, such as climate and vegetation types, to support more optimal land management strategies.
