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.

nt Zohran Mamdani, the first Muslim Mayor of New York City, it asks what talking about Mamdani does for these netizens as members of their own polity, and develops the concept of comparative civic imagination: the use of a foreign political figure as a discursive instrument for evaluating, criticising, and re-imagining one’s own democracy. The study applies qualitative Computer-Mediated Discourse Analysis (CMDA) to public Indonesian-language discourse about Mamdani on platform X between 1 November 2025 and 30 June 2026, drawing on a purposively constructed corpus of 213 units—134 citizen-account units as the analytical core and 79 media-account units as contextual triangulation—recoded by comparative function and affective register rather than by stance toward the figure. The findings show that Indonesian netizens engage Mamdani through a comparative architecture organised by the vernacular frame “Mamdani Indonesia” (45% of citizen units) and enacted through three repertoires: analogical personification, institutional benchmarking, and counterfactual transposition. The discourse is animated by civic despair—crystallised in the idiom “Indonesia could never”—which operates as a participatory rather than an apathetic affect, while a domestic value-compatibility filter of doctrinal, sectarian, and purity tests renders the admired model discursively non-transferable, closing a recursive loop theorised here as a digitally networked spectre of comparisons. The article shifts the analysis of transnational digital engagement away from cosmopolitan and diasporic assumptions toward the vicarious engagement of non-diasporic publics, re-theorises despair as a mode of civic engagement, and recovers Benedict Anderson’s spectre of comparisons for platform-era political communication in the Global South.

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.

sed vertical hydroponic farming system integrated with LED grow light technology and catfish aquaponics. The proposed system combines vertical hydroponics and aquaponics to optimize plant growth and water utilization. Internet of Things technology enables real-time environmental monitoring through an Arduino Uno microcontroller integrated with LDR, soil moisture, pH, and NPK sensors. The obtained sensor data is processed using the Mamdani Fuzzy Logic algorithm, which performs fuzzification, rule inference, aggregation, and defuzzification to generate adaptive control decisions for irrigation, nutrient circulation, and LED grow light intensity. This research uses the Research and Development (R&D) method through prototype development and performance evaluation for 30 days using spinach (Amaranthus spp.) and mustard greens (Brassica juncea) as test plants. Experimental results showed that the developed system successfully maintained stable environmental conditions, with soil moisture ranging between 69–72%, a pH value between 6.4 and 6.6, and optimal nutrient availability. Plant growth increased significantly. The integration of IoT, AI and aquaponics improves cultivation efficiency, enabling environmental control as a smart and sustainable solution for urban agriculture.

between supply and demand, resulting in excess stock and budget waste. Uncertain demand for drugs is a factor that complicates decision-making in stock provision. This study aims to optimize drug stock management using the Mamdani fuzzy logic method, which is capable of handling data uncertainty and modeling information linguistically. Three input variables are used, namely initial stock, demand, and number of visits, with the output being the final stock. The process involves fuzzification, inference based on IF–THEN rules, and defuzzification using the centroid method. The results show that the developed system has a good accuracy level with a MAPE value of 17.52%, which means that this model is effective in providing optimal and efficient drug stock recommendations in a veterinary clinic environment.
