Abstract

Background. This study examines posthumanist themes and ecological consciousness in the science fiction works of Dewi “Dee” Lestari, one of Indonesia’s most influential contemporary authors whose narratives frequently challenge anthropocentric worldviews. The background of this research lies in the growing global interest in posthumanist discourse, which critiques human-centered epistemologies and emphasizes the entanglement of humans, technology, and the natural environment. Purpose. The aim of this study is to analyze the narrative strategies, philosophical motifs, and ecological representations through which Dee constructs a posthumanist imaginary that destabilizes traditional boundaries between human and non-human agents. Method. The study employs a qualitative textual analysis method grounded in literary ecocriticism and posthumanist theory, drawing on close reading techniques and thematic mapping. Results. The results reveal that Dee’s narratives articulate a model of relational existence in which technology, consciousness, and ecological systems are interdependent rather than hierarchically ordered. Her work foregrounds ethical responsibility, cosmological humility, and the dissolution of rigid subject-object distinctions, offering a vision of scientific and spiritual evolution embedded within ecological awareness.   Conclusion. The study concludes that Dee’s science fiction significantly contributes to Indonesian literature by integrating posthumanist philosophy with ecological sensibility, encouraging readers to rethink the role of humans within a broader planetary network. This research highlights the relevance of Indonesian speculative fiction to global debates on ecological crisis and posthuman futures.

Abstract

The exponential escalation of computational density required by modern Artificial Intelligence (AI) and Large Language Models has pushed traditional air-cooled data center infrastructures to their thermodynamic limits. This study investigates the efficacy of single-phase liquid immersion cooling as a transformative solution to manage the extreme thermal flux of next-generation AI accelerators. Adopting a quantitative experimental design, we benchmarked a high-density GPU cluster submerged in a proprietary dielectric fluid against a standard forced-air baseline under intensive MLPerf training workloads. The research focused on evaluating key performance indicators, including Power Usage Effectiveness (PUE), processor junction temperatures, and total energy consumption over a 168-hour stress test. Results demonstrate that the immersion architecture achieved a near-ideal PUE of 1.04, representing a 34% efficiency improvement over the air-cooled control group. Furthermore, the liquid medium maintained GPU core temperatures 20°C lower than the baseline, effectively eliminating thermal throttling events and enhancing computational stability. The study concludes that shifting from aerodynamic to hydrodynamic cooling is not merely an efficiency upgrade but a physical prerequisite for the sustainable scaling of exascale AI infrastructure, offering a viable pathway to decarbonize the expanding digital economy.
