Introduction: Clean and Healthy Living Behavior (PHBS) is an important indicator in improving health status, particularly among university students as a productive age group. Health knowledge plays a role as a predisposing factor in the formation of healthy behavior. Individuals with a good level of health knowledge tend to have higher awareness and motivation to implement PHBS. Conversely, a lack of knowledge may lead to behaviors that pose health risks. Objective: This study aimed to determine the relationship between the level of health knowledge and clean and healthy living behavior (PHBS) among students at Universitas Muhammadiyah Semarang. Methods: This study employed a quantitative design with a cross-sectional approach. The sample consisted of 55 students, including students from health-related and non-health-related faculties. Samples were selected using an accidental sampling technique, namely respondents who were encountered and willing to complete the questionnaire at the time of data collection. The research instruments were a health knowledge questionnaire and a PHBS questionnaire. Data analysis was conducted using univariate and bivariate analysis with the Spearman test. Results: The results showed that the majority of respondents had good health knowledge (89.1%) and good PHBS (90.9%). The Spearman test results showed a p-value of 0.001 (p < 0.05), indicating a significant relationship between the level of health knowledge and PHBS. Conclusion: It can be concluded that the better the level of students’ health knowledge, the better the implementation of clean and healthy living behavior.

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.

The Indonesia Smart Program (Program Indonesia Pintar/PIP) is a government initiative aimed at ensuring equal access to education for students from underprivileged families, including those at the junior high school (SMP) level. However, at the school level, the management of PIP recipient data still faces several challenges, particularly in data searching and utilization, due to the increasing volume of data and the use of simple or manual search methods. These conditions can lead to delays in obtaining information and reduce the accuracy of decision-making. Therefore, an effective information retrieval system is needed to manage and search PIP recipient data efficiently. This study aims to design and develop an Information Retrieval System for PIP recipient data at the junior high school level using the Term Frequency–Inverse Document Frequency (TF-IDF) method. The TF-IDF method is applied to assign weights to terms in each document, enabling the system to identify and rank documents based on their relevance to user queries. The test results show that the system is able to measure document relevance accurately, where documents D3 and D4 obtain the highest similarity value of 0.099586089 and are classified as highly relevant, while other documents show lower similarity values down to zero. These results are also supported by graphical visualization, which helps users compare relevance levels more clearly. Thus, the implementation of the TF-IDF method has proven to be effective in supporting accurate, efficient, and systematic searching and management of PIP recipient data at the junior high school level.
