Balancing Heritage in Urban Expansion: Gedung Sate’s Resilience towards a JunkSpace Landscape
This paper argues that the vertical stratification of formal, informal, and historical layers in Bandung contributes to the emergence of Junkspace, particularly around Gedung Sate, a heritage government building embedded in a rapidly urbanizing context. Drawing on Koolhaas’ concept of Junkspace and theories of spatial heterogeneity, the research explores how informal peripheries intersect with formal urban growth, creating porous hybrid spaces that defy conventional spatial order. Through qualitative spatial analysis, street-level observations, and time-lapse figure-ground studies from 2017 to 2025, the study reveals that informal structures adapt to, rather than displace, formal ones. This coexistence generates architectural incoherence marked by non-hierarchical, fused uses. The findings suggest that Gedung Sate is evolving into a form of Junkspace not merely through the erosion of spatial order but through active transformations that blend historical permanence with dynamic informal encroachments, reflecting the complex and layered realities of contemporary Bandung.

Unveiling the Significance of Gedung Sate Architecture within the Context of Sustainable Cultural Tourism
One of the iconic historical buildings in Bandung, Indonesia, known as Gedung Sate, represents a unique architectural fusion of European and local styles. As a significant cultural landmark and a major tourist destination, its preservation and management are paramount. This study aims to analyze the cultural significance of Gedung Sate's architecture and to evaluate its role within the framework of sustainable cultural tourism. This research employed a qualitative case study approach, utilizing architectural observation, semi-structured interviews, and documentary analysis. The analysis is guided by the cultural significance framework of the ICOMOS Burra Charter and supplemented by conceptual models of tourism impact. The findings reveal that Gedung Sate's significance is dualistic, derived from its value as both a colonial aesthetic masterpiece and a symbol of post-colonial national struggle. Furthermore, while tourism numbers appear sustainable, the analysis exposes significant vulnerabilities in the building's physical carrying capacity and socio-economic benefits. The novelty of this study lies in its application of the Burra Charter to a prominent Indonesian heritage site and its structured, critical evaluation of sustainable tourism that moves beyond simplistic metrics. This research contributes to the discourse on heritage management, offering insights for balancing preservation and tourism at similar sites.

Reducing Emissions through Low-Carbon and Biomaterials: The Case of Green Office Enjoy, Paris
Drastic transformation in the construction industry is required to achieve global net-zero targets while accommodating the continuing need to build to anticipate the growing population. With the increase implementation of energy efficient building, the significant of embodied carbon becomes higher. The use of biomaterial has great potential to reduce building emissions. This paper presents a case study that has been built with engineered timber components, and examines to what extent, a further reduction of embodied emissions can be performed. Three material replacements were proposed to further decarbonize the building emissions, and the embodied carbon reductions resulted by changing the timber specification and fly ash use in concrete mixture were assessed quantitatively with embodied carbon assessment. Results show that by replacing the building materials with lower carbon options, the embodied carbon of the case study can be reduced from 52 to 242 tons of CO2e or 2.82 to 12,99 kgCO2e/m2.

The Land is The Icon: Disappearing Architecture on Natural Force
This paper reimagines architectural landmarks within the hills of Labuan Bajo, proposing an approach where architecture seamlessly integrates with the landscape rather than asserting dominance. The study examines how design strategies can amplify rather than overshadow the natural environment, positioning nature as the true landmark through ephemeral architecture. Using Plowright’s force-based framework within an architectural competition, the research employs a research-by-design methodology to iteratively refine solutions that dissolve built interventions into the terrain. By integrating Labuan Bajo’s topographical and visual characteristics, the design leverages adaptive modularity and sustainable strategies to ensure perceptual fluidity within the site’s ecological and cultural context. This approach contributes to landmark design by demonstrating how architecture can function as a dynamic extension of the landscape, fostering harmony rather than visual competition.

Pembacaan Ruang Kontradiktif sebagai Tantangan Perancangan Kota: Studi Kasus Kawasan Siola, Surabaya
Abstrak Dalam perencanaan ruang publik di kawasan cagar budaya, arsitek dan perencana umumnya lebih fokus pada aktivitas formal dan mengabaikan aktivitas informal. Aktivitas informal di ruang publik muncul tanpa perencanaan namun sejatinya dipicu oleh aktivitas formal yang dirancang. Fenomena ini membentuk suatu ritme ruang urban yang kontradiktif sehingga menghasilkan makna ruang publik yang ambigu. Penelitian ini mengkaji fenomena kontradiksi ruang sosial publik yang timbul akibat informalitas sebagai dampak revitalisasi kawasan cagar budaya dengan mengambil Kawasan Siola di Surabaya sebagai studi kasus. Studi dilakukan dengan menggunakan pendekatan kualitatif berdasarkan teori rhythmanalysis dari Lefebvre dengan metode wawancara dan observasi lapangan. Pembacaan ruang dilakukan dengan mengkaji lima variabel: elemen fisik dan non-fisik, jenis kegiatan, pola penggunaan ruang, objek pengisi ruang, serta dimensi waktu. Temuan menunjukkan bahwa aktivitas informal memiliki peran penting dalam pembentukan ruang kota. Informalitas menjadi elemen kunci dalam menanggapi dinamika ruang kontradiktif dan menjadi tantangan dalam pendekatan desain urban di kawasan perkotaan, khususnya kawasan cagar budaya. Abstract In the process of planning of public spaces within heritage areas, architects and planners tend to focus on formal activities while neglecting informal ones. Informal activities in public spaces usually emerge without prior planning; however, it may be triggered by the designed formal activities. This phenomenon generates a contradictory urban spatial rhythm, resulting in an ambiguous meaning of public space. This study examines the phenomenon of social space contradiction arising from informality as an impact of heritage area revitalisation, taking the Siola area in Surabaya as a case study. The research employs a qualitative approach based on Lefebvre’s theory of rhythmanalysis, using interviews and field observations. Spatial interpretation is conducted through five variables: physical and non-physical elements, types of activities, spatial use patterns, spatial objects, and temporal dimensions. The findings reveal that informal activities play a significant role in shaping urban space. Informality becomes a key element in responding to the dynamics of contradictory space and presents a challenge for urban design approaches, particularly in heritage areas.

An Analysis of the Challenges to Achieving Sustainable Practices in Nigeria's Construction Sector
This study investigates the key barriers to the adoption of sustainable construction practices in Nigeria, focusing on regulatory, organizational, social, cultural, and technological factors. Utilizing a mixed-methods approach, the research combines qualitative case studies and interviews with quantitative survey data to identify these challenges. The findings highlight the multifaceted and interconnected nature of these barriers, with regulatory challenges—such as outdated building codes, insufficient legislative support, and bureaucratic inefficiencies—emerging as the most significant. Social and cultural resistance to change, coupled with limited public awareness of sustainable construction benefits, further complicate adoption. Technological challenges, including high costs of green materials and a shortage of skilled professionals, are also key obstacles. The study suggests that Nigeria can draw valuable lessons from other developing countries, such as South Africa, India, and Indonesia, where similar challenges have been addressed through proactive policies and innovative practices. Recommendations for overcoming these barriers include modernizing building codes, strengthening leadership in sustainability within the construction sector, and launching comprehensive public education campaigns to shift societal attitudes. The study further advocates for increased investment in green technologies and the development of local supply chains to reduce costs and enhance the accessibility of sustainable construction materials. By adopting these strategies, Nigeria can promote sustainable building practices and contribute to global knowledge on overcoming barriers to sustainability in developing economies.

Lateral Soil Movement Due to Installation of a Single Pile using Jack-in Method
Lateral movement of soil due to the installation of a single pile using jack-in method was studied. The piles considered in this study were 15 piles of the diameter 800 mm. The lateral soil movement was predicted using Plaxis 2D, which incorporated cavity expansion theory as prescribed displacement. The results were compared to the recorded data from the field and those determined using several formulas. The comparison shows that the lateral movement of soil due to the installation of a single pile can be closely estimated using Plaxis 2D that employed a linear prescribed displacement of 0.42r at the pile head and zero at the pile tip. Lateral displacement of soil predicted using Plaxis 2D agrees well with data measured from the field both at the ground surface and along the depth of piles.

Magnification Factor in Partial Capacity Design for Multitude Bay Buildings
Partial capacity design (PCD) is an alternative method to design earthquake-resistant structures. PCD leads to a partial side sway mechanism as its collapse mechanism. Therefore, a magnification factor is applied in designing elastic column (usually perimeter column) in order to make it stronger than the plastic columns. The purpose of this research is to try a proposed magnification factor for buildings with long span. Two concrete buildings located in Surabaya at soft soil, consists of 6- and 10-story, were studied. Each building has 9 spans in the x- and y-directions, each 8 meters in length. The buildings were designed with the same columns dimension. The elastic columns were located in the building perimeter. The buildings were evaluated using non-linear time history analysis which shows that partial side sway mechanism was achieved.
Financial Performance of Construction, Property, and Trading Companies Based on Working Capital, Liquidity Ratio, and Profitability Ratio
An investor needs to do an analysis to choose the best investment. This decision should be carried out with the right calculation and analysis of the company's performance. This research evaluates financial performance of several companies based on their working capital, liquidity, and profitability. Profitability ratio indicates company’s ability to make a profit. Liquidity ratio indicates company’s ability to pay debt in due date condition. Working investment shows that working capital needed by the company. Profitability and liquidity of the company is determined by financial ratio. This research is focused on investigating financial performances of three types of companies, namely construction, developer, and trade industry. The results of the liquidity and profitability ratios show that developer companies has the best liquidity ratio compared to construction and trading companies. The results of calculation of working capital show that construction companies need the minimal working capital than the other companies.
