Abstract

Literature serves as a medium for expressing psychological realities, particularly through characters shaped by trauma and emotional struggle. Specifically, Ziggy Zezsyazeoviennazabrizkie’s In the Land of Pepper portrays the inner world of Salva, a child enduring neglect and domestic violence, whose psychological conflicts reflect broader societal issues. Despite existing studies on literary psychology, few have focused on Indonesian novels that depict childhood trauma using Freud's psychoanalytic theory. This study aims to analyze the protagonist’s psychological condition through Freud’s structural model—Id, Ego, and Superego—complemented by Jungian symbols and Eriksonian psychosocial theory. Results indicate Salva employs defense mechanisms such as denial, repression, and fantasy projection to navigate trauma, with the “land of pepper” functioning as a symbolic refuge. The novelty lies in the integrative psychoanalytic approach applied to a contemporary Indonesian text, highlighting the character’s fragmented psyche and imaginative resilience. Implications include the potential for literature to foster emotional literacy and trauma awareness in educational settings, as well as providing a foundation for further interdisciplinary research between literature and psychology.Highlight : The study analyzes the inner psychological struggles of the protagonist using Freud’s Id, Ego, and Superego. Childhood trauma and emotional neglect form the core of Salva’s development and coping mechanisms. Literature is presented as a medium for psychological reflection and emotional education through character exploration. Keywords : Literary Psychology, Main Character, Inner Conflict, Trauma, Ziggy Zezsyazeoviennazabrizkie

Abstract

General Background: Efficient route planning is a fundamental aspect of logistics, directly impacting operational costs, fuel consumption, and customer satisfaction. Specific Background: A logistics company based in Batam has been facing inefficiencies in spare part delivery operations due to suboptimal routing strategies. Knowledge Gap: While various routing solutions exist, few are tailored to accommodate dynamic, real-world constraints such as vehicle capacity and varying delivery points in mid-scale logistics operations. Aim: This study aims to optimize delivery routes using the Ant Colony Optimization (ACO) algorithm by modeling the problem as a Vehicle Routing Problem (VRP) with specific operational constraints. Results: The implementation of ACO significantly reduced total travel distance compared to the company’s existing manual routing approach. As a result, fuel consumption was lowered, delivery times improved, and customer service enhanced. Novelty: Unlike generic routing systems, the proposed ACO-based model dynamically adapts to real operational variables through pheromone-based local and global updates, improving the solution iteratively with each cycle. Implications: This research provides a practical and intelligent decision-support framework for logistics planning, demonstrating that metaheuristic algorithms such as ACO can robustly handle complex delivery challenges and be scaled to broader logistics applications Highlights: Improves route efficiency using ACO in real delivery operations. Reduces distance, fuel usage, and delivery time significantly. Provides a scalable model for intelligent logistics planning. Keywords: Ant Colony Optimization, Vehicle Routing Problem, Logistics Efficiency, Route Optimization, Metaheuristic Algorithm
