Abstract

This study examines the spatial efficiency and sustainable site development of the Poltekkes Riau Tower, a vertical educational facility, using the Greenship New Building Version 1.2 framework established by the Green Building Council Indonesia (GBCI). It focuses on the Appropriate Site Development (ASD) category and assesses green area ratio, site selection, accessibility, transportation, landscape quality, microclimate control, and stormwater management. The building scored 5 out of 17 points (29.4%), indicating shortcomings in bicycle access, landscaping, and runoff mitigation. The evaluation process involves four key steps: (1) Scoring Analysis, which quantifies compliance with the Greenship criteria; (2) Spatial Mapping of green cover, access, and hydrology based on site plans and field data; (3) Gap Identification, which compares actual conditions with benchmarks; and (4) Recommendation Formulation to enhance sustainability through passive design, landscape optimization, and integrated stormwater systems. The findings provide insights for improving site sustainability in future vertical educational buildings located in tropical urban settings.

Abstract

This study analyzes the influence of public visual perception on urban navigation and city image through the role of landmarks in Pekanbaru. The background stems from the declining visual legibility of the city due to rapid spatial development and architectural homogenization. Five main landmarks were examined: An-Nur Grand Mosque, Zapin Monument, Soeman HS Library, the Riau Governor’s Office, and Idrus Tintin Art Pavilion. A mixed-method approach was applied using questionnaires from 105 respondents, field observations, and Multidimensional Scaling (MDS) analysis. The results indicate that An-Nur Grand Mosque and Soeman HS Library function as the city’s visual-affective anchors with high legibility and civic pride. Zapin Monument serves as a directional marker with strong cultural symbolism, while the Governor’s Office is visually dominant but weak in collective identity. Idrus Tintin Art Pavilion represents cultural symbolism but plays a limited navigational role. The study concludes that Pekanbaru’s city image emerges from the interaction of architectural quality, navigational function, and symbolic-emotional values, recommending enhanced visibility, integrated wayfinding systems, and cultural revitalization in urban planning.

Abstract

Metaphorical architecture translates cultural and natural phenomena into readable spatial narratives. This article develops a framework of five variables—source metaphor, key attributes, domain transfer, spatial narrative, and symbolic legibility—synthesized from comparative precedent studies (Libeskind’s Jewish Museum Berlin and the Aceh Tsunami Museum) and applies it to the design of the Painan Maritime Museum in West Sumatra. Local sources such as the traditional pincalang boat, Indian Ocean waves, and communal fishing activities are transformed into a ship-oriented elongated mass, undulating façade, net-patterned secondary skin, and sequential linear circulation forming a symbolic “voyage”: embarkation, tension, climax, reflection, and epilogue. The analysis reveals a balance between iconic legibility and conceptual depth, enabling visitors to intuitively perceive local maritime identity. This study contributes to the development of a transferable design methodology for metaphor-based museums and provides contextual site recommendations for the coastal landscape of Carocok Beach, Painan.

Abstract

Landmarks play a vital role in shaping the city’s image as orientation markers and visual identity elements. Pekanbaru, the capital of Riau Province, has experienced rapid development that produced many iconic buildings, yet systematic studies based on public perception remain limited. This research aims to identify the main landmarks of Pekanbaru City and analyze the visual characteristics influencing their legibility. A mixed-method approach was applied through field observation, visual documentation, and a questionnaire survey involving 150 purposively selected respondents. Descriptive and statistical analyses using SmartPLS were conducted to examine relationships among visual perception variables (singularity, location, uniqueness, memorable) and landmark recognition. The findings reveal that An-Nur Grand Mosque, Soeman HS Library, and the Riau Governor’s Office are the most recognized landmarks. Location and memorable factors have significant positive effects, while uniqueness shows a negative influence. The study emphasizes that enhancing landmark design and spatial arrangement strengthens urban navigation and visual identity in Pekanbaru.
