Abstract

Maintaining the temperature and pH of water in fish farming is important to maintain the survival of the commodities being cultivated. Snakehead fish as one of the freshwater fish cultivation commodities, live in a temperature range of 25° to 32°C, and a pH of 4,5 to 6. Changes in temperature and pH due to  differences in day and night and weather conditions can be mortal for the fish. To help the fish farmers maintain water quality, in this research a prototype of IoT based temperature and pH monitor and control was built using Arduino microcontroller, that  can be accessed through a mobile application on Android smartphone. The test results show that the prototype has successfully control the temperature by turning the heater on when it dropped below 25°C, turned the acid solution pump on when the pH felt below 4.5, and alkaline solution pump when pH was above 6. Continuous sensor readings are able to  maintain the stability of water quality.

Abstract

Lake Maninjau experiences periodic upwelling events that disrupt water quality, harm fish stocks, and pose socioeconomic challenges to surrounding communities. This study aimed to enhance upwelling prediction accuracy by integrating Vector Autoregressive (VAR) time series modelling with Support Vector Machine (SVM) classification. A five-year dataset (2020–2024) of daily climate variables surface temperature, precipitation, and wind speed was collected from NASA. Data stationarity was confirmed using Box-Cox transformations and Augmented Dickey-Fuller tests, while Granger Causality analysis revealed bidirectional relationships among the variables. The optimal forecasting model, VAR(17), was selected based on the Akaike Information Criterion (AIC), ensuring residuals met white-noise criteria. K-means clustering then labelled potential upwelling days, and these labels were employed to train SVM classifiers. An interactive dashboard was developed using Python and Streamlit to facilitate real-time forecasts and classification outputs. The VAR(17) model produced highly accurate forecasts, reflected by minimal error metrics (e.g., RMSE < 0.60). SVM classification of potential upwelling events achieved strong performance, consistently attaining F1-scores above 0.95. By merging time series forecasts with event classification, the hybrid VAR–SVM framework outperformed single-method approaches in identifying and predicting upwelling episodes. This integrated modelling strategy effectively addresses the complexity of upwelling in Lake Maninjau, enabling timely decision-making for fisheries management and local tourism stakeholders. Future work may incorporate additional environmental indicators (e.g., dissolved oxygen, pH) and extend dashboard functionalities to bolster sustainable resource management and community resilience

Abstract

The study of takhrīj hadith has so far been dominated by a normative approach that positions the assessment of rijāl primarily as a reproduction of classical authority, so that the process of verifying narrator and sanad data often lacks a systematic, transparent, and methodologically traceable evaluation mechanism. This condition has implications for the limited consistency and replicability of hadith assessment in the context of contemporary hadith studies that demand higher scientific accountability. This study aims to reconstruct the methodology of takhrīj based on rijāl through the integration of the principles of jarḥ wa al-Taʻdīl with an evidence-based approach, so that the assessment of narrators and sanad is not only based on normative authority, but also on structured data management and verification. The study uses a qualitative-analytical approach with a critical analysis of rijāl literature, works of jarḥ wa al-Taʻdīl, and the scientific evidence framework that has developed in the modern research tradition. The results of this study indicate the formation of a takhrīj methodological framework that places rijāl data as the primary basis of analysis through the stages of source inventory, cross-verification of narrator information, assessment of the evidential weight of jarḥ and taʻdīl, and consistent synthesis of findings in the evaluation of sanad. This framework allows for a more structured, transparent, and consistent hadith assessment process, while minimizing subjectivity and fragmentation of assessment. The implications of this research lie in strengthening the validity and reliability of hadith assessment, as well as its contribution to developing a takhrīj methodology that is adaptive to the demands of contemporary hadith studies without abandoning the foundations of classical scholarship.

Abstract

This study aims to analyze the E-Relationship Marketing strategy implemented by PT. Travel Al-Amar Madani Masyhur Medan through social media in an effort to maintain pilgrim loyalty amidst the increasingly competitive Umrah travel industry in the digital era. The research method used is descriptive qualitative with a case study approach. Data collection was conducted through in-depth interviews with management and pilgrims, observation of social media activities (Instagram, Facebook, and WhatsApp), and documentation. Data analysis used data reduction, data display, and conclusion drawing techniques. The results show that the implementation of E-Relationship Marketing is carried out through four main dimensions: service personalization, digital community building, responsive interaction, and consistency of Islamic brand character. The use of social media is proven effective in increasing trust and emotional closeness of pilgrims, leading to loyalty in the form of repeat orders and recommendations (advocacy). The main obstacle found is the digital literacy gap among elderly pilgrims, which the company addressed through simpler and more intensive communication approaches on the WhatsApp platform.

Abstract

This study examines parental mental readiness from a Qur’anic perspective through an integrative analysis of Surah Luqman (13–19) and Surah An-Nisa’ (9) based on Tafsir Al-Mishbah. The research is motivated by the dominant emphasis on financial readiness in family formation, which often neglects the mental and spiritual preparedness of parents. This study employs a qualitative approach using library research and thematic exegesis analysis. The findings reveal that parental mental readiness is a multidimensional construct consisting of five main dimensions: monotheism, reciprocity, emotional regulation, social morality, and responsibility. The model aligns with modern parenting theories, such as emotional intelligence and authoritative parenting, yet offers a distinctive contribution through the integration of spiritual dimensions as its foundation. Theoretically, this study contributes to the development of constructive thematic exegesis, while practically providing a conceptual basis for Islamic family education. Future studies are recommended to empirically test this model
