The issue of stunting continues to pose a threat to the future generation of Indonesia. Local plants with high nutritional content include moringa leaves. Apart from moringa leaves, eels also have high nutritional value. Innovation in the formulation of noodle combining moringa leaves and eels is highly needed as a functional food for stunting prevention. The research aimed to determine the level of acceptance of subjects towards the formulation of moringa leaf and eel combination noodles and to assess the effectiveness of the noodle formulation in increasing or changing the weight of toddlers. A pure experimental study with an RAL design was conducted in July-August 2023, involved 30 toddlers and 30 mother-toddler subjects selected through purposive sampling. Data analysis included organoleptic tests to measure the subjects' preferences for the noodle formulation and Paired sample t-test to assess the impact of the noodle formulation on changes in toddlers' weights. The research findings indicated that on average, mothers' preferences for moringa leaf and eel noodles, particularly in terms of color and texture, received positive ratings, while aroma and taste were rated moderately positive. The toddlers' weights before consuming moringa leaf and eel noodles was 9,73 kg, and after consumption, the average weight increased by 0,48 kg to 10,21 kg. The research conclusion confirms that the moringa leaf and eel noodle formulation are potential to have a positive impact on increasing toddlers' weights.

Time series forecasting memiliki aplikasi yang luas dalam berbagai bidang seperti keuangan, ekonomi, meteorologi, dan pengelolaan rantai pasokan. Penelitian ini bertujuan untuk mengevaluasi kinerja model Gated Recurrent Unit (GRU) yang mendalam dalam konteks prediksi data time series. Akurasi prediksi time series sangat penting untuk pengambilan keputusan yang lebih baik dan efisien. GRU diperkenalkan sebagai varian Recurrent Neural Networks (RNN) yang lebih efisien dan efektif dalam menangani data time series. RNN sering digunakan untuk tugas ini, namun memiliki kelemahan dalam mempelajari ketergantungan jangka panjang akibat masalah vanishing gradient. Penelitian ini mengusulkan penggunaan model GRU mendalam untuk meningkatkan akurasi prediksi data time series. Arsitektur model yang diusulkan terdiri dari tiga lapisan GRU dengan 64 unit masing-masing, diikuti oleh satu lapisan output dense. Dataset yang digunakan dalam penelitian ini adalah dataset time series yang terdiri dari AQI, Weather, Exchange Rate, dan ETT. Model dilatih menggunakan optimizer Adam dan loss function mean squared error, dengan jumlah epoch sebanyak 100 dan batch size 32. Data dibagi menjadi set training dan testing dengan rasio 80:20. Kinerja model dievaluasi menggunakan metrik Mean Absolute Error (MAE) dan Root Mean Squared Error (RMSE). Hasil eksperimen menunjukkan bahwa model GRU mendalam menghasilkan prediksi yang lebih akurat dibandingkan dengan model ARIMA, RNN, dan LSTM. Model GRU mendalam menunjukkan kemampuan yang lebih baik dalam mempelajari ketergantungan jangka panjang dalam data time series, sehingga meningkatkan akurasi prediksi. Hasil penelitian ini memberikan kontribusi signifikan dalam bidang time series forecasting dan dapat menjadi alternatif yang lebih efektif dibandingkan model tradisional dan model machine learning lainnya.

This article explores the philosophical underpinnings of the falsification theory proposed by Karl Raimund Popper, a key figure in the philosophy of science in the 20th century. Utilizing a library research approach and descriptive analytical methods, the study delves into the core principles and implications of falsification as a model of scientific reasoning. Unlike the verificationist paradigm that seeks to confirm theories through accumulating supportive evidence, Popper’s falsification theory asserts that scientific theories must be testable and open to refutation through empirical observation and experimentation. The article examines how falsification provides a more rigorous framework for distinguishing scientific knowledge from non-scientific claims by promoting continual testing and revision. It further discusses the broader methodological implications of falsification for scientific inquiry, emphasizing its relevance across multiple disciplines. By fostering a mindset of skepticism and critical inquiry, falsification theory challenges researchers to remain open to new evidence and alternative explanations, thereby supporting the evolution of science as a dynamic and self-correcting enterprise. This analysis highlights the enduring importance of Popper’s contribution to research methodology and the development of progressive scientific thought.

Mental behavior is the activities that occur in a person's mind when solving mathematical problems. These activities are important to explore in problem solving, but exploration of activities is still rarely done by lecturers. This study aims to describe mental activities in solving mathematical problems of students who have high mathematical abilities and field independent (FI) and field dependent (FD) cognitive styles. This study uses a descriptive qualitative method with the subjects of the study being mathematics education students at Syiah Kuala University in the 2023 academic year. Data collection techniques were carried out using problem-solving tests and interviews. Data analysis was carried out by data reduction, presentation, and drawing conclusions. Data validity was carried out by time triangulation. The results of the analysis obtained mental activities in problem solving displayed by students with high mathematical abilities and FI cognitive styles were more complete than students with FD cognitive styles in the activities of reading questions, understanding questions, linking information and explaining solutions, but the mental activities displayed by FI were the same as FD at the calculation and manipulation stages. Therefore, it is necessary to provide experience to FD students to

Digital media technology has a significant impact on life and using it for preaching (da’wah) is very important to expand the reach of the audience, including the younger generation. This study uses a descriptive qualitative approach. A Google Form containing 22 open-ended survey questions was distributed to various universities in four provinces in eastern Indonesia. A total of 29 survey responses were recorded, but only 9 responses could be analyzed using theory-based data triangulation techniques. Informants highlighted two main themes: appealing aspects of digital da'wah and challenges and criticisms of digital da'wah. The findings emphasize the need for digital da’wah that adds to religious insight and is engaging. It also found that the younger generation dislikes preachers who tend to justify their own group and discredit other groups.

Critical philosophy in education assumes that students are so naive and unable to read social reality critically, and this also happens in Islamic education. Paulo Freire tries to promote the importance of student-centred education, active participation and critical consciousness in education. This study aims to: (1) explore Freire's ideas about praxis; (2) explore Freire's thoughts on democracy; (3) explore Freire's thinking about critical consciousness; (4) integrate the concepts of praxis, democracy and critical consciousness in Islamic education. This is literature research which involves review of literature that is relevant to Freire's concepts and their application in Islamic education. The findings of this study are: (1) Praxis allows students to link Islamic knowledge and values with concrete actions in life; (2) Democracy promotes student participation in decision-making and open dialogue, enabling them to actively contribute to learning; (3) Critical consciousness helps students understand the structure of society and analyze their understanding of Islamic teachings critically; (4) The concepts of praxis, democracy and critical consciousness in Islamic education provides opportunities for students to integrate religious teachings with their life experiences, understand the social context and develop a critical understanding of Islam.
