Dalam filsafat pendidikan Islam, sumber utama pengetahuan adalah al-Qur'an dan Sunnah, yaitu wahyu yang diberikan oleh Allah kepada Nabi Muhammad saw. al-Qur'an dianggap sebagai wahyu ilahi yang sempurna dan menjadi sumber pengetahuan yang otoritatif dalam semua aspek kehidupan, termasuk pendidikan. Sunnah Nabi Muhammad saw juga menjadi sumber pengetahuan yang penting, karena merupakan contoh nyata dari penerapan ajaran al-Qur'an dalam kehidupan sehari-hari. Metode pencarian pengetahuan dalam pendidikan Islam melibatkan pembacaan, studi, dan refleksi terhadap al-Qur'an dan Sunnah. Pendidikan Islam juga mendorong penggunaan akal dan rasionalitas dalam memahami ajaran agama. Namun, akal tidak boleh bertentangan dengan wahyu, dan pemahaman akal harus selaras dengan ajaran al-Qur'an dan Sunnah. Proses pembentukan pengetahuan dalam pendidikan Islam melibatkan tahap-tahap seperti memahami teks-teks suci, mengkaji tafsir dan hadis, mempelajari sejarah dan konteks ajaran agama, serta menghubungkan pengetahuan dengan praktik kehidupan sehari-hari. Pendidikan Islam juga menekankan pentingnya pembentukan karakter yang baik dan moral yang kuat dalam proses pembentukan pengetahuan.

Batik ikat celup adalah salah satu teknik pembuatan batik yang memiliki ciri khas tersendiri, dimana proses pengikatan kain diikuti dengan pencelupan warna untuk menciptakan motif yang unik dan penuh ekspresi. Meskipun teknik ini tidak se-populer batik tulis atau cap, batik ikat celup memiliki nilai estetika yang tinggi dan menyimpan kekayaan budaya yang mendalam. Teknik ini melibatkan pengikatan kain pada bagian-bagian tertentu yang ingin dipertahankan warnanya, diikuti dengan pencelupan dalam pewarna alami atau sintetis untuk menciptakan pola-pola yang bervariasi. Proses pengikatan ini memungkinkan terciptanya motif dengan gradasi warna yang indah, yang sering kali memiliki makna filosofis dan simbolis dalam budaya Indonesia. Penelitian ini bertujuan untuk memberikan pemahaman yang lebih mendalam tentang batik ikat celup, baik dari segi teknik pembuatan, karakteristik motif, serta relevansinya dalam konteks budaya dan ekonomi kreatif Indonesia. Melalui studi literatur, wawancara dengan pengrajin batik, dan observasi langsung terhadap proses pembuatan batik ikat celup, penelitian ini mencoba mengungkap bagaimana teknik ini berperan dalam pelestarian warisan budaya Indonesia, serta tantangan dan peluang yang dihadapi oleh para pengrajin batik. Selain itu, penelitian ini juga mengeksplorasi kontribusi batik ikat celup terhadap industri tekstil dan pasar global, mengingat semakin meningkatnya permintaan akan produk-produk tekstil yang bernilai seni dan budaya tinggi. Hasil dari penelitian ini menunjukkan bahwa batik ikat celup memiliki kekayaan simbolik yang mencerminkan hubungan manusia dengan alam, kehidupan sosial, dan spiritualitas. Meskipun teknik ini menghadapi tantangan dari perkembangan teknologi dan perubahan pasar, batik ikat celup masih tetap memiliki tempat penting dalam budaya dan industri kreatif Indonesia. Pelestarian teknik ini sangat penting untuk menjaga keberlanjutannya, baik melalui pendidikan, promosi, maupun dukungan terhadap pengrajin lokal. Dengan demikian, batik ikat celup tidak hanya menjadi bagian dari warisan budaya, tetapi juga memiliki potensi besar dalam pengembangan ekonomi kreatif yang berkelanjutan.

This research uses a qualitative approach with a descriptive qualitative method. This research was conducted at MIs Nurur Rahman Tamanan, located at Jl Kebun Bibit No 02 Tamanan, Tamanan District, Bondowoso Regency. The purpose of this research is to analyze the marketing strategies for interactive education at the school and to identify the factors that support and hinder the implementation of these strategies. To provide an understanding of interactive education marketing strategies, data was obtained through field observations and in-depth analysis. The research results show that product, price, promotion, and people are the main indicators in the interactive education marketing strategy. Through school public relations and appropriate pricing, this strategy aims to create a good image. It was found that people's involvement and promotion are important factors in the success of educational service marketing. Nevertheless, the research also found several obstacles. This includes financial difficulties and a lack of public knowledge about interactive education.

Implementation of the Naive Bayes algorithm for the classification of recipients of the Certificate of Inability to Pay (SKTM) assistance in Pesanggrahan Village. The classification process is carried out manually and using the RapidMiner application to validate the results. Manual calculations are carried out by calculating the probability of each attribute, such as occupation, age, income, marital status, vehicle, and asset ownership. The calculation results show that the probability for the "eligible" category is 0.097254, while the "uneligible" category has a probability of zero, so that the resident is classified as eligible to receive assistance. And, the calculation results using RapidMiner show results that are consistent with manual calculations. The Naive Bayes algorithm successfully classifies data with high accuracy, ensuring that assistance is more targeted to residents who meet the criteria. The implementation of this method provides an effective solution to overcome the problem of inaccurate distribution of assistance, increasing efficiency and transparency in decision-making by village officials. Thus, the Naive Bayes algorithm can be used as a tool in the process of determining recipients of assistance that is more objective and data-based.

Student attendance in lectures plays a crucial role in academic achievement and the quality of learning. The Decision Tree algorithm is used to analyze student attendance patterns with a dataset containing 6,607 entries from Kaggle, comprising 20 related attributes. Using RapidMiner, the analysis process includes data splitting, model building, and performance evaluation. The model achieved 49.96% accuracy, with the best performance in the "Medium" class (50.40% precision, 98.12% recall) but showed weaknesses in the "High" and "Low" classes. These results highlight the importance of data-driven approaches to designing effective strategies, such as rescheduling or improving teaching methods, to enhance student participation.

Data mining, or data mining is the process of collecting and processing data to extract important information. The stages in the data mining process are useful for finding a particular pattern from a large amount of assessment data. This goal is to find out and form student data clusters based on grades so that they become a cluster, so that the results of student clusters can be a reference in improving student grades in the next learning process. The results of the evaluation and assessment of students are carried out by teaching staff or teachers in conducting assessments during the learning process. In the learning process there are 2 assessment categories, namely UTS and UAS student grades. The results of grouping student grade data using the K-Means clustering method show that based on the results of student data clusters in one semester, cluster 0 is obtained with 7 students, cluster 1 is 3. The results of testing using rapid miner show that there are 7 students who have grades with a good average and there are 3 students with a poor average grade.

Demand and supply are fundamental concepts in microeconomics that influence market decisions. This article aims to explore the application of mathematical models in explaining the interaction between demand and supply in the market for goods and services. Through an economic mathematics approach, we analyze the demand and supply functions, as well as the application of market equilibrium using calculus techniques and function analysis. The proposed mathematical model focuses on how price and quantity are determined in competitive markets, along with the impact of external factors such as consumer income, related goods prices, and production costs. This study also examines applications in economic policy-making to balance the market.
