The phenomenon of preaching in non-conventional spaces such as nightclubs has drawn attention because it presents a form of religious message delivery that adapts to the socio-cultural context of marginalized audiences. Gus Miftah, as a contemporary preacher, utilizes these spaces, both directly and through digital media, to convey inclusive and communicative preaching. This study aims to analyze the process of encoding da'wah messages by Gus Miftah in the video “LC Karaoke Bertanya, Gus Miftah Ngaji di Boshe” and the audience’s reception (decoding) through comments on YouTube. Using a descriptive qualitative approach and Stuart Hall’s encoding-decoding theory, data were collected through video documentation and purposive observation of comments. The results show that the da'wah messages are constructed contextually and humanistically, with a relaxed, humorous style and language familiar to nightlife workers. The analysis reveals three audience reception positions: the majority fully accept the message, a small portion critically engages with the context, and others reject the preaching method as incompatible with traditional values. These findings indicate that the audience’s cultural, social, and religious backgrounds strongly influence the response to da'wah. This study enriches the discourse on digital da'wah and emphasizes the importance of understanding the audience as active subjects in communication. Conclusion: A contextual preaching approach effectively penetrates non-conventional spaces and is widely accepted, despite resistance from conservative and critical audiences.

This study examines the application of the Lagrange method and Particle Swarm Optimization (PSO) in solving the Economic Dispatch problem at the Tanjung Jati B Steam Power Plant (PLTU). The main objective is to compare the effectiveness of both methods in optimizing load distribution among generation units and to evaluate potential operational cost savings compared to actual operating conditions. The optimization model minimizes a quadratic generation cost function, subject to system load demand and the power output limits of each unit. Simulation data includes daily load distribution and fuel-related parameters such as calorific value and fuel price. The results show that the Lagrange method yields an average power output of 2,367 MW, equal to the real condition, while PSO produces 1,966 MW, which is 16.94% lower. In terms of cost savings, PSO achieves an average saving of IDR 938,501, while the Lagrange method and real operation yield average savings of IDR 1,078,064 and IDR 1,073,076 respectively. In percentage terms, Lagrange shows 12.95% higher savings than PSO and 0.46% higher than the actual condition. This study highlights the importance of integrating optimization methods in power plant operations to improve efficiency and reliability of electricity supply.
