Application Of Mamdani's Fuzzy Logic In Modeling The Prediction Of Drug Abuse Levels In Padang City

Cindy Yunaldi, Yusli Yenni
Abstract: Drug abuse is a problem that can be influenced by various interrelated factors. This study aims to apply Mamdani Fuzzy logic in predicting the level of drug abuse in Padang City based on several factors obtained from documentation… umentation and interviews. The input variables used consist of the Age of the Perpetrator, Environment, Socializing, Gender, and Family, while the output variable is the Level of Drug Abuse with Low and High categories. The research stages include data collection, determining variables and fuzzy sets, fuzzification, forming if-then rules, inference using the minimum operator, composition using the maximum operator, and defuzzification using the centroid method. A total of 64 fuzzy rules are used to connect the combination of input variables with the output. Testing is done through manual calculations and implementation using MATLAB. The test results show that the output categories from manual calculations and MATLAB are the same in three test data, namely High, High, and Low. These results indicate that the Mamdani Fuzzy method can be used in modeling the level of drug abuse based on the variables used.

THE EPISTEMOLOGY OF SHARAF SCIENCE: A HISTORICAL OVERVIEW AND ITS CONTRIBUTION TO ARABIC LINGUISTICS

Fatoni, Ahmad Sirfi, Jamil, Muhammad
Abstract: Arabic morphology constitutes a fundamental branch of classical Arabic linguistics, focusing on morphological word transformation (tashrif) and derivational morphology. Despite more than a millennium of development, epistemological… temological inquiry into ilmu sharaf — concerning its sources of knowledge, methods of rule formation, and scientific validity — remains considerably limited in contemporary academic literature, with existing studies tending toward normative and pedagogical orientations that neglect its fundamental philosophical dimensions. This article aims to examine the epistemology of ilmu sharaf from the philosophy of science perspective, tracing its historical genealogy from the early Islamic codification period through to modern Arabic linguistics, and analyzing its contributions to contemporary Arabic morphology. The research employed a qualitative library research method with historical, epistemological, and comparative-linguistic approaches, utilizing critical analysis of relevant primary and secondary sources. The findings reveal that ilmu sharaf possesses a robust epistemological foundation derived from the Qur'an, hadith, classical Arabic fushah poetry, and qiyas (analogical reasoning), and was developed through the methods of sima' (documentation), istinbath (inference), and ta'lil (rational justification) by linguists of the Bashrahn and Kufahn schools. Ontologically, its subject matter is morphological word transformation that produces semantic change; axiologically, it functions to preserve Arabic linguistic purity and facilitate Qur'anic comprehension. The contributions of ilmu sharaf to modern Arabic linguistics are demonstrably significant, particularly in the development of root-and-pattern morphology theory, derivational semantics, and Arabic natural language processing (NLP). These findings indicate that the classical sharaf tradition is not merely historically relevant but also carries important methodological implications for contemporary Arabic computational linguistics.

ANALYSIS OF ENERGY EFFICIENCY PERFORMANCE USING THE MEMBERSHIP FUNCTION (MF) METHOD IN A FUZZY LOGIC CONTROL SYSTEM FOR RESIDENTIAL SPLIT AIR CONDITIONERS (AC)

Susilo, Susilo, Lalay, Ario Azadi
Abstract: A fuzzy logic-based control system in household split-type air conditioners (AC) offers an alternative approach to reducing excess energy consumption without compromising thermal comfort. This study aims to test the effectiveness… ctiveness of three types of membership functions (MF), namely triangular, trapezoidal, and Gaussian, in improving energy efficiency and the stability of room temperature and humidity control. Simulations were performed using MATLAB software with the Mamdani fuzzy inference method and centroid defuzzification technique. The three MF were tested using 30 sets of temperature and humidity data to analyze their effect on fan speed and power consumption. The simulation results show that the trapezoidal MF provides the highest energy efficiency of 57.24%, followed by the Gaussian MF at 56.80% and the triangular MF at 53.71%. These findings indicate that fuzzy systems can significantly reduce energy consumption compared to conventional air conditioner controllers. This research is expected to serve as a reference in the development of more energy-efficient intelligent control systems.

THE ROLE OF PANCASILA LEARNING IN DEVELOPING SOCIO POLITICAL AWARENESS AMONG P.IPS UIN MALANG STUDENTS

Risky Alamsyah, Muhammad Rizal Firdaus, Rifa Arum Tazkya Maharani, Deliana Putri, Ahmad Farhan Abdilla
Abstract: This research highlights the strategic role of Pancasila learning in developing social and political awareness among students of Social Science Education Study Program (P.IPS) at Maulana Malik Ibrahim State Islamic University… rsity Malang. The background of this research is rooted in the low level of participation and awareness of social and political issues among the younger generation in the midst of globalization. To understand this phenomenon, the research used a descriptive qualitative approach with field research methods through structured interviews and direct observation. Social awareness indicators were measured based on the theory of Yoyo Sudaryo and Agus Ribowo, while political awareness refers to the theory of Almond and Verba. The data were then analyzed using the Miles and Huberman model, which includes data reduction, data presentation, and inference. The results showed that Pancasila learning is able to increase students' social and political awareness through the internalization of values such as empathy, honesty, tolerance, and active participation in community life. In addition, this learning also encourages students' participation in political activities, strengthens their awareness of their rights and responsibilities as citizens, and forms a critical attitude toward various social issues. The implications of the results of this study indicate the importance of strengthening Pancasila learning as a character building tool for students who are active, critical, and empowered to face socio-political challenges in the future.
