Abstract

This study aims (1) to make a tool that knows the level of turbidity and acidity of the water using an LDR sensor and a pH sensor. (2) To connect between LDR, PH and Arduino. (3) To read the turbidity and acidity of the water using an LDR sensor and an arduino uno-based pH sensor. The research method used is SDLC (System Development Life Cycle) model with the prototype method, while the steps in the prototype are gathering needs, rapid design processes ,building prototypes and evaluations, improvements, data collection techniques, observations, interviews and literature studies. The results of this study indicate that (1) The design of a prototype for detecting turbidity and acidity of well water uses an LDR sensor which can determine the cloudiness or clarity of water and uses a pH sensor to determine the acidity and alkaline levels of the water. (2) The implementation of this arduino-based prototype turbidity and acidity detector can be used by people who do not know the pH level of the water which is good for use.

Abstract

Media digital telah mengubah praktik komunikasi, khususnya dalam strategi komunikasi penyampaian pesan, pola interaksi, dan cara audiens memaknai pesan edukatif.Penelitian ini bertujuan untuk menganalisis pemanfaatan media digital dalam komunikasi edukasi dengan fokus pada strategi komunikasi, interaksi dan partisipasi, serta pemaknaan audiens terhadap pesan atau konten. Penelitian ini menggunakan pendekatan kualitatif dengan jenis deskriptif-interpretatif. Data dikumpulkan melalui observasi konten media digital,wawancara, dan dokumentasi yang selanjutnya dianalisis secara tematik. Hasil menunjukkan bahwa strategi komunikasi edukasi disusun secara adaptif melalui penyajian pesan yang ringkas, visual, dan kontekstual. Audiens berperan aktif dalam proses pembelajaran dengan beragam bentuk, mulai dari respons sederhana hingga diskusi mendalam. Selain itu,pemaknaan audiens dipengaruhi oleh latar belakang pengetahuan, literasi digital, dan kredibilitas sumber pesan. Penelitian ini menegaskan bahwa efektivitas komunikasi edukasi dalam pemanfaatan media digital ditentukan oleh integrasi desain, interaksi, dan proses pemaknaan pesan audiens.

Abstract

Fiqh, as the result of human ijtihad in understanding Islamic law, possesses complex dimensions and diverse schools of thought. This article comprehensively discusses the dimensions of fiqh, encompassing normative, social, philosophical, and historical aspects, and analyzes the schools of fiqh that developed within the Sunni (Hanafi, Maliki, Shafi'i, Hanbali) and Shia (Ja'fari) traditions. Through a qualitative approach based on literature review with historical, normative, and philosophical perspectives, this article finds that differences in legal istinbath methodology between schools of thought, influenced by geographical and social factors, and differing understandings of texts, are actually a blessing that enriches the intellectual treasury of Islam. The relevance of the plurality of schools of thought in the contemporary era lies in their flexibility in responding to the dynamics of modern society and the concept of moderation within schools of thought as a middle ground between narrow fanaticism and excessive liberalism

Abstract

Waqf has great potential to support social and economic welfare in Indonesia, but its implementation still faces various challenges. This article aims to analyze the regulation of waqf in Indonesian positive law, its implementation problems, and the effectiveness of regulations in improving public welfare. The research employs a normative juridical method with statutory and conceptual approaches. The findings indicate that Law Number 41 of 2004 concerning Waqf has recognized cash waqf and productive waqf, but its implementation faces problems such as low certification of waqf lands, disputes with heirs, and regulatory limitations that restrict the space for the Indonesian Waqf Board (BWI). The effectiveness of waqf law is not yet optimal, as evidenced by the gap between waqf asset potential (IDR 3,500 trillion) and cash waqf realization (IDR 3.5 trillion). This research recommends revision of the Waqf Law, acceleration of waqf land certification, strengthening of public literacy, improvement of nazhir professionalism, and development of productive waqf models integrated with national development programs
