Learning from timber folded grid structure for Mosque in Indonesia
No full textTimber has been used in traditional Indonesia short-span roof structure. This short span timber structure still depended on the maximum length and thickness of the timber. Despite the introduction of the trusses system, timber constructions are still limited to short span roofs. Steel and concrete are still more popular to be used as long span roof structure material. This phenomenon was also shown in mosque roof structure development. The timber roof structure was replaced by steel and concrete long-span roof, especially in form of dome structure.
This paper presents the complexity of design to construction process of Nurul Hasanah Aceh Mosque in Palu City which pioneers the long-span single-layer folded grid timber roof structure in Indonesia. This article discusses design exploration of the mosque which showed the inseparable structural, construction, and architectural aspect in design process. The construction could serve as milestone for the development of long-span timber roof construction in Indonesia. This article also recommends several technical and computational improvement to further develop complex long-span timber structures in Indonesia
Indonesian Bond Yields: Inflation, Fed Rates, And Exchange Rate Effects
No full textThis research aims to analyze the effects of Indonesian
inflation, the rise of the US Fed rate, and the exchange rate on the
yield of Indonesian government bonds. This study employs a
quantitative approach using secondary data obtained from reliable
sources, such as the Bloomberg database, the official website of
Bank Indonesia, and the official website of the Federal Reserve.
The sample comprises 132 months of macroeconomic rates and
prices, covering 10 years from 2012 to 2022. Data analysis
included descriptive statistics, classical assumption tests, and
stationarity testing. While previous studies have analysed the
effects of these factors on government bond prices, this study
investigates explicitly their impact on government bond yield in
Indonesia. The results show that inflation and the exchange rate
positively affect the Indonesian government bond yield. However,
the rise in the US Federal Reserve rate does not significantly drive
changes in the Indonesian government bond yield

Exploring the impact of digital tourism experience on behavioral intentions: the role of vivid memory among international visitors to Surabaya
No full textThe development of digital technology affects our daily life, including the tourism industry. The trend of digital tourism or smart tourism technology in a tourist destination can increase the uniqueness and value of a tourist destination. This research aims to analyze the influence of digital experience on foreign tourists� behavioral intentions in Surabaya with vivid memory as a mediation variable. Digital experience refers to experiences obtained through digital technology, such as websites, social media, and destination applications. Vivid experiences that cause vivid memories, often encourage tourist behavior, such as revisit intentions or recommendations to others. This research uses quantitative methods with Partial Least Squares (PLS) data analysis techniques involving 147 foreign tourists who are or have visited Surabaya. The research results show that digital experience has a positive and significant influence on vivid memory and tourists behavioral intentions. Vivid memory is proven to act as a mediating variable in the relationship between digital experience and behavioral intentions. Therefore, the use of digital technology in Surabaya tourist destinations in an effort to provide a digital experience for foreign tourists visiting Surabaya needs to be improved
PENERAPAN DESAIN UNIVERSAL DI ERA NEW NORMAL PADA FASILITAS KANTOR KEMITRAAN INDUSTRI DI SURABAYA
No full textHumans have various characteristics, from height, race, habits, and
others, therefore the needs of humans, in general, are also different. With
this difference, the interior design used to support the needs must be used
by all humans. This need is called universal design. On the other hand, the
world is being hit by the COVID-19 virus which is changing peoples habits.
In fact, the implementation of universal design in interiors is less than
optimal, coupled with a significant change from the new normal problem
that makes many changes to the architecture, especially interior design in
public spaces. With this description, this design focuses on the needs and
problems of universal and new normal design with the design results in the
form of applying concept applications in interior design such as circulation,
overall design, and furniture design that adapts to concept needs. The
design uses the design thinking method with 9 stages (understand,
observe, point of view, ideate, prototype, test, storytelling, pilot and
business model) with the final design result in the form of a set of working
drawings and 3D interior drawings

Effects of Short-Term (20-Day) Alternate-Day Modified Fasting and Time-Restricted Feeding on Fasting Glucose and IGF-1 in Obese Young Women
No full textBackground: Obesity is a metabolic condition that may impair insulin sensitivity and disrupt glucose homeostasis. Since insulin and glucose affect insulin-like growth factor-1 (IGF-1), disruptions in this axis may elevate the risk of chronic diseases. Intermittent fasting (IF) modulates metabolic parameters, but the impacts on glucose regulation and IGF-1 remain underexplored. This study aimed to assess the short-term effects of two IF types, time-restricted feeding (TRF) and alternate-day modified fasting (ADMF), on fasting blood glucose (FBG) and IGF-1 in obese young women. Methods: A quasi-experimental pretest–posttest control group design was conducted over 20 days. The 31 subjects were allocated into ADMF (n = 10), TRF (n = 11), and Control (n = 10). After excluding dropouts and outliers, the final sample consisted of 22 subjects (ADMF = 7, TRF = 8, Control = 7). FBG and IGF-1 serum were measured pre- and post-intervention. Results: The FBG post-intervention significantly increased in TRF (p = 0.001) and ADMF (p = 0.036) groups, but not in Controls. Only the TRF group showed a significant reduction in IGF-1 levels (p < 0.001). Nevertheless, the ADMF group exhibited substantial decreases in body weight (p = 0.047) and visceral fat (p = 0.017). Conclusions: A 20-day IF in obese young women induced distinct metabolic effects: TRF lowered IGF-1, ADMF reduced adiposity, and both
regimens increased FBG. These findings suggest that early changes in glucose regulation are highly dependent on the specific dietary regimen used. Specifically, TRF predominantly influences endocrine regulation (IGF-1 axis), while ADMF favours adiposity reduction. The concurrent rise in FBG may reflect a transient shift in glucose homeostasis during the early stages of fasting
Reiterating the Spirit of Place: A Framework for Heritage Site in VR
Full text linkThis study proposes and tests a virtual reality (VR) framework aimed at reiterating the Spirit of Place (SiP) of heritage sites, conceived as a perceiver’s perception of place formed through the dynamic interplay of tangible and intangible influences within a given location. The framework applies Gilles Deleuze’s concepts of ‘difference in itself’ and ‘repetition for itself’ to create interpretive VR experiences that evoke SiP by integrating natural features, built structures, cultural memories, historical narratives, cultural narratives, and symbolic associations. Through a controlled experiment involving both video and VR interactions with heritage sites, participants reported elevated emotional connections and a deeper engagement with SiP in the VR environment. This confirms that VR can serve as an effective medium for heritage preservation, capturing the site’s distinct identity and fostering embodied engagement shaped by users’ memories and cultural familiarity. These findings validate the framework’s potential to convey the unique identity of heritage sites, offering a transformative tool for virtual heritage applications
Comparative Performance of Precast Column-To-Foundation Connections: A Review
Full text linkSince the introduction of precast concrete as a structural element in the early 20th century, precast concrete has evolved significantly into an essential construction technology in various modern construction projects. This is due to several advantages of precast concrete, such as time efficiency, relatively lower costs, good quality control, and environmental friendliness. However, precast con- crete also has disadvantages when applied as part of a seismic-resistant building framework, primarily in the connection between elements, which does not per- form as well as monolithic joints in terms of structural performance. The precast column-to-foundation connection is one of the most critical connections, as it experiences the largest axial-moment combination forces in a structure. Com- monly used types of precast connections include pocket connections, baseplates, anchor connections, and grouting sleeves. The results of previous research reviews suggest that pocket connections demonstrate reliable structural performance, pro- vided the column’s embedment length into the foundation exceeds 1.0 Diameter. Meanwhile, the structural performance of baseplate and anchor connections is significantly influenced by the thickness of the baseplate, the number of anchors, and their configuration. For grouting sleeve connections, the key factors are the diameter and spacing of the sleeves, as well as the length of the reinforcement bars. On average, test results for precast column-to-foundation connections indicate that all the connections above can achieve the strength of monolithic joints. However, structural performance characteristics such as ductility, energy dissipation, and stiffness degradation require further modifications to match the performance of cast-in-place monolithic joints
