Coffee husk is an agro-industrial waste with significant potential to be utilized as a renewable energy source through the fast pyrolysis process. This study aims to analyze and optimize gas production from the fast pyrolysis of coffee husk biomass using a screw reactor through single-particle-based Computational Fluid Dynamics (CFD) simulations. The simulations were conducted by varying the operating temperature at 500°C, 600°C, and 700°C to examine pressure distribution, heat transfer, particle temperature, and the formation of pyrolysis products, namely bio-oil, biogas, and biochar. The modeling was performed using COMSOL Multiphysics 6.2 with a numerical approach to represent thermal phenomena and biomass decomposition reactions during the pyrolysis process. The simulation results indicate that increasing temperature significantly affects the rate of heat transfer and the temperature distribution of coffee husk particles. At 600°C, heat transfer and temperature distribution are more uniform compared to 500°C, although heating at the particle core is not yet fully optimal. The pressure distribution shows a stable flow of pyrolysis gas from the bottom to the top of the reactor. In terms of products, increasing temperature leads to a reduction in biochar and bio-oil formation due to the occurrence of secondary reactions, while biogas production increases. The highest gas production is achieved at 700°C, indicating the most optimal condition for maximizing gas yield from fast pyrolysis. Therefore, single-particle-based CFD simulation can be used as an effective tool to understand pyrolysis mechanisms and optimize process parameters in a screw reactor.

The role of the Director of Photography (DoP) is fundamental in translating narrative concepts into visual language within audio-visual productions. This study examines the implementation of cinematographic techniques applied by the DoP in producing the human interest video feature "Porter: Ketidakpastian yang Dikerjakan" (Porter: Uncertainty at Work). The feature documents the daily lives of porters at Bandung Station, shedding light on the occupational uncertainty they face as informal sector workers. The research employs a qualitative descriptive method with a production-based approach, analyzing four key cinematographic elements: type of shot (long shot, medium shot, close up), camera angle (eye level, high angle, low angle), camera movement (panning, tilting, tracking shot, static shot), and framing (rule of thirds, balanced composition). Findings indicate that each technique was applied with deliberate intention to reinforce the narrative, emotional depth, and thematic meaning of the work. Long shots established the station environment as a dynamic, unpredictable workspace; medium shots captured the psychological nuance of waiting and uncertainty; close ups revealed intimate emotional detail; and varied camera angles constructed the power dynamics between porters and their environment. Camera movements supported visual continuity and audience engagement, while framing principles ensured compositional coherence throughout. The study contributes practical insights into the role of cinematography in non-fiction storytelling, particularly in conveying the lived realities of marginalized workers.
