The author's motivation for undertaking this study stems from a previous observation that instructors continued to employ an expository method that was monotonous and devoid of variety. The instructor primarily employs the lecture method to impart the learning material, which restricts their ability to utilise infrastructure and facilities such as mind mapping and concentration for the students. This form of inquiry employs descriptive qualitative research methodology, specifically characterising a symptom associated with a current event. By utilising data collection methods such as documentation, interviews, and observation. Class V students served as the primary informants, while the Islamic Religious Education Instructor and the School Principal provided supplementary information. Following this, the author conducts data analysis through data reduction, data presentation, and conclusion drawing from the study. The findings of the study indicate that: 1) The expository method was implemented with PAI subjects. After conducting research on its learning applications, it has been optimised. Because educators possess a professional demeanour and impart knowledge in accordance with their academic credentials. 2) Possessing assets that serve as corroborating elements in the instructor's implementation and utilisation of learning resources pertaining to Islamic religious education that are accessible and deemed satisfactory in their efficacy. However, there are impediments: a) the teacher's capacity to design learning is constrained (insufficient), b) the length of the teacher's explanations is excessive, c) the reliance on textbooks lacks creativity and is monotonous, and d) educators' endeavours to surmount challenges are also hindered. when the expository method is applied to PAI subjects:. 3) Efforts made by educators to overcome inhibiting factors in the application of expository methods, especially in PAI subjects, can be overcome by developing expository methods, such as using teaching aids, and supplementing with worksheets, and using textbooks that are less imaginative, rigid, and emphasized. on factual learning, memorization, and so on. Thus, it can be stated that the application of the expository method in the implementation of the Islamic Religious Education learning process produces a good learning process and can improve student learning achievement.

Diabetes Mellitus (DM) is a metabolic disorder characterized by high blood sugar levels due to insulin deficiency. Factors causing Diabetes Mellitus (DM) are lifestyle which includes diet, lack of exercise, monitoring blood sugar, and medication. Most people do not realize that they have DM and only find out when they experience severe symptoms. To avoid this, the k-Nearest Neighbor (KNN) method can be used to predict the possibility of developing diabetes. The aim of this research is to classify diabetes mellitus using the K-Nearest Neighbor (KNN) method and make people more aware of the risk of disease through healthy lifestyle changes. Data received from the Dharma Husada Clinic is categorized based on researchers' needs, including age, BMI, insulin, skin thickness, glucose, diabetes, genetics, and insulin. This research was carried out in three main steps: dataset input, preprocessing, and evaluation. The first stage is data analysis which begins by entering a dataset to train and test the model, where each data element has certain characteristics (attributes) and classes. Preprocessing steps include training data generation and data cleaning, which includes sanitization, lowercase, normalization, stopwords, stemming, and tokenizing. The final step is evaluating. Evaluation includes building an evaluation model and measuring the level of accuracy, building a predictive model, and saving the model. This research shows that the K-Nearest Neighbor (KNN) method can be used to classify diabetes mellitus (DM), but especially in a small dataset consisting of 245 dates and 8 attributes it is not accurate for patients aged 30 years. . A k value that is too small can cause overfitting, and a k value that is too large can cause underfitting. However, if the amount of data is small, the choice of k can have a large impact.

The method used is normative legal research utilizing library references and interviews with academic and practitioner experts as research subjects. This study is descriptive, systematically analyzing primary, secondary, and tertiary legal materials along with relevant facts. The conclusion of this research is that the granting of mortgage rights to foreign banks follows the procedures stipulated in Ministerial Regulation No. 5 of 2020 from the Ministry of ATR/BPN. The registration process for mortgage rights is conducted electronically, but foreign banks such as China Banking Corporation Limited must first register through the financial partner application. The main challenges in implementing electronic mortgage rights guarantee primarily stem from legal uncertainties regarding the registration of foreign creditors through the financial partner application managed by the Ministry. Additionally, there are technical challenges due to IT systems that are not yet fully prepared. Improving the quality of human resources is also necessary, given the constraints faced at the land office due to a shortage of personnel, while demand from the public and service users remains high.

The transformation of affirmative action policies in the digital era serves as a strategic step to improve the Gender Empowerment Index (GEM) and accelerate gender equality in Indonesia. These policies focus on enhancing women's access to economic, political, and educational sectors, leveraging opportunities provided by digital technology. However, several challenges remain, such as limited internet access, low digital literacy, patriarchal social norms, and underrepresentation of women in STEM (Science, Technology, Engineering, and Mathematics) sectors. The government has implemented several initiatives, including a 30% quota for women's representation in parliament, empowering women-owned MSMEs through Kredit Usaha Rakyat (KUR), and offering scholarships to increase women's participation in STEM and technology fields. In addition, affirmative policies within state-owned enterprises (BUMN) aim to promote female leadership in strategic positions. Despite some progress, the gender gap in the digital economy and the risk of gender-based violence online remain significant issues that require further attention.Policy recommendations include improving access to technology and digital literacy for women, providing incentives for companies that promote gender equality, and strengthening protection against online gender-based violence. Collaboration between the government, private sector, and civil society is essential to ensure the successful implementation of affirmative action policies in the digital era. This transformation is expected not only to enhance the IDG but also to empower women to actively contribute to inclusive and sustainable economic development.
