Abstract

Formula milk is packed with essential nutrients. It contains beneficial components such as carbohydrates, proteins, fats, vitamins, sodium, DHA, and more. High-quality formula milk should not lead to gastrointestinal issues such as diarrhea, vomiting, or problems with digestion, nor should it cause coughing, breathing difficulties, or skin reactions due to an incorrect formula choice. This research aims to explore how mothers select suitable formula milk for their babies. The study utilizes the SIMPLE ADDITIVE WEIGHTING (SAW) method to determine alternative options based on pre-assigned weights and criteria. Following this, the ranking method is applied to identify the best alternative. According to the findings, five alternatives were evaluated: MORINAGA CHIL KID, LACTOGEN, SGM, BEBELOVE, and NUTRIBABY ROYAL 1. Additionally, five criteria were considered: Milk Price, Safety (Bpom Certification, Halal, etc.), Nutritional Content (Protein, Calcium, Iron, Vitamins, etc.), Taste (Natural Sweetness, Vanilla, Honey), and Market Availability.

Abstract

Tuberculosis (TB) was still a global challenge in the world of health and required special attention to increase the level of patient compliance with treatment. This study aimed to explore the relationship between patient knowledge, attitudes, and actions and the level of adherence to taking medication in TB patients at the Pulmonary Polyclinic of Subulussalam City Hospital. The study used an observational analytical design with a cross-sectional approach. The research population involved all TB patients undergoing treatment at Subulussalam City Hospital, with a sample of 76 respondents selected through accidental sampling. Data were collected through interviews using the MMAS-8 questionnaire, and data analysis was carried out using the chi-square test. The majority of respondents showed a high level of knowledge (47.37%), poor attitudes (59.21%), and good actions (64.47%), but the level of compliance was low (46.05%). Statistical analysis showed that there was a significant relationship between knowledge (p=0.000), attitudes (p=0.014), and actions (p=0.010) with the level of adherence to taking medication. The knowledge, attitudes, and actions of TB patients at the Lung Polyclinic of Subulussalam City Hospital had a significant effect on their level of compliance in taking medication. Efforts were needed to increase patient understanding and special approaches to increase compliance to support the success of TB therapy.

Abstract

Educator certificates are official documents that play a crucial role for teachers, as they serve as legal proof of professional competence and are required for various administrative purposes, such as professional allowance applications, promotion, transfer, and institutional accreditation. Along with the increasing number of educators in Indonesia, the volume of educator certificate data managed by educational institutions has also grown significantly. However, certificate management is still largely conducted in a conventional manner, functioning merely as digital or physical archives without an effective search mechanism, resulting in inefficiencies and difficulties in retrieving relevant documents. Therefore, an information retrieval approach is needed to support fast and accurate document searching. This study aims to analyze and implement an information retrieval system for educator certificates using the Cosine Similarity method. The research data consist of educator certificate documents, including professional educator certificates, training certificates, and competency certificates. The retrieval process involves text preprocessing, term weighting using TF-IDF, and similarity measurement using Cosine Similarity. The results show that document d1 (Professional Mathematics Educator Certificate) has the highest similarity value to the query “educator certificate,” as it contains all query terms with relatively high TF-IDF weights. Document d3 ranks second due to partial term similarity, while document d2 has the lowest similarity value because it shares only one common term with the query. These findings indicate that the Cosine Similarity method is effective in ranking educator certificate documents based on their content relevance in an objective and measurable manner. The proposed system can improve the efficiency and accuracy of educator certificate document management and retrieval in educational institutions.

Abstract

Verbal bullying is a serious issue in elementary school environments that is often underestimated, despite its significant impact on students’ psychological well-being and academic performance. This study aims to analyze the impact of verbal bullying on students’ learning concentration and academic achievement at Elementary School. The research employed a qualitative approach using a case study design. The participants consisted of six informants selected through snowball sampling, including the principal, teachers, and students. The researcher acted as the main research instrument, supported by interview guidelines, observation sheets, and documentation tools. Data were collected through in-depth interviews, observations, and document analysis. Data analysis was conducted using the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. Data validity was ensured through technique and source triangulation. The findings indicate that verbal bullying is the most dominant form of bullying occurring at Elementary School, particularly in the form of mocking physical characteristics and mentioning parents’ names. Verbal bullying directly affects students’ learning concentration, leading to decreased focus during classroom activities, reduced learning motivation, and declining academic achievement. In addition, verbal bullying causes psychological impacts such as fear, discomfort, low self-confidence, and emotional distress among students. The study concludes that verbal bullying not only affects students’ social and psychological aspects but also has direct implications for the learning process and academic performance. Therefore, serious preventive and intervention efforts from schools are necessary to create a safe and supportive learning environment.

Abstract

The urgency of this research stems from the knowledge gap regarding contextual factors contributing to the underuse of learning media in rural elementary schools, which has not been adequately addressed in previous research, which has tended to focus on urban contexts. This study aims to examine teachers' perceptions at Sugayang Public Elementary School regarding the underuse of learning media in the learning process, as well as the factors that contribute to it. The method used was a descriptive qualitative method, utilizing in-depth interviews as a data collection technique. The data were then analyzed using data reduction, data display, and conclusion drawing techniques according to Miles and Huberman. The results showed that teachers experienced difficulties in using technology, difficulties in creating learning media, and the perception that using media was time-consuming. This reveals an important pattern that the underuse of learning media is a systematic problem rooted in the TPACK gap that is not supported by practical time management solutions. These findings imply that changes in learning practices will not occur simply through the provision of generic technology tools or training; rather, bottom-up and contextual solutions are needed. The novelty of this research lies in the in-depth qualitative approach applied to the under-researched context of rural elementary schools, which has not been studied before. This research contributes through recommendations for the implementation of a peer-mentoring program and the development of a ready-to-use digital learning media bank, thus offering valuable insights for future research with relevant stakeholders.

Abstract

This study investigates the role of parental support in improving the learning abilities of elementary school students, with a particular focus on first-grade students at Tahfidzul Qur'an Elementary School. The research was motivated by the growing recognition that parental involvement is a key factor influencing children's academic development and learning success during the early years of education. A qualitative approach with a case study design was employed to gain an in-depth understanding of how parental support contributes to students' learning experiences. Data were collected through classroom observations, semi-structured interviews with teachers and parents, and documentation of relevant school records.
