Simulation and Evaluation Hydrogen-rich Syngas Production from Palm Kernell Shell Through Gasification
No full textThe increasing global demand for energy, coupled with the depletion of fossil fuel reserves, has prompted the urgent need for alternative and sustainable energy sources. Biomass, particularly palm oil waste such as palm kernel shell (PKS) presents as an alternative solution due to its abundance, high calorific value, and low moisture content. This study investigates the production of syngas from PKS through gasification using Aspen PlusTM process simulation software. The simulation is divided into pre-treatment, gasification, and separation stages, employing R-Stoic, R-Yield, and R-Gibbs reactor blocks to model drying, decomposition, and thermodynamic equilibrium, respectively. Two gasifying agents, steam and air, were evaluated under varying temperature conditions and equivalence ratio (ER) ranging from 0.19 to 0.27. The results indicate that both temperature and ER significantly influence syngas composition, particularly the production of H2 and CO, while higher ER values tend to reduce carbon efficiency. Steam gasification produced higher hydrogen yields compared to air. Simulation outputs showed strong agreement with experimental data, validating the model’s accuracy. This study demonstrates the potential of PKS gasification for renewable energy generation and highlights the effectiveness of process simulation for system design and optimization prior to industrial implementation

Budaya sebagai Komoditas Streaming: Ekologi Media dan Komodifikasi Tradisi Indonesia dalam Film Netflix
No full textThis research explores how Indonesian culture is represented and commodified in locally produced Netflix films. Through an analysis of Guru-Guru Gokil (2020) and Nightmares and Daydreams (2024), the study examines how Indonesia’s social and spiritual values undergo a transformation of meaning within the digital media ecosystem. Employing a qualitative descriptive approach grounded in McLuhan’s Media Ecology Theory and Mosco’s Political Economy of Communication, this research reveals that Netflix functions not merely as a distribution platform, but as a global cultural environment that reconstructs the meaning of local culture to fit global market preferences. The commodification of culture occurs through aestheticization, simplification of meaning, and cultural datafication. Consequently, Indonesian culture in the streaming era emerges as a global entertainment product, representing local identity within the framework of platform capitalism..Penelitian ini membahas bagaimana budaya Indonesia direpresentasikan dan dikomodifikasi dalam film Netflix produksi lokal.
