The use of atrium in hospital buildings accelerating the patient's healing process and reduce the impression of stress on hospital buildings. However, the presence of the atrium can also pose a fire hazard because it can be a means of spreading smoke quickly. This study determines the effect of atriums in hospital buildings on the level of life safety in the event of a fire. The study was conducted at two hospitals in Bandung and Jakarta, Indonesia. The level of life safety is assessed through the difference between the time needed for the evacuation, referred to as RSET, and the time taken by smoke to cause a critical condition for occupants, called ASET, where RSET must be shorter than ASET. The analysis carried out on two physical configurations: open and closed atrium, and the results of this study showed that with an open atrium, the smoke quickly covered the evacuation route before the evacuation process completed, or ASET<RSET. The fire room door must be closed, and the smoke-barrier must be installed around the atrium to prevent the spread of smoke into patient rooms, thus fulfill the ASET<RSET criteria.

This study is aimed to examine which configurations of mortar covering give the best fire protection for the bamboo-plaster wall system. The research is done in two stages, first is the non-standardized pre-test stage which results will become the basis for determining the specimen specification. In the second stage, the specimen with the best fire resistance level is tested with a standardized test referred to SNI 1741-2008 and ISO 834-1-1999. Fire resistance performance was measured according to integration and insulation level expressed in minutes. In the pre-testing stage, bamboo-wall configurations with woven bamboo, and mortar plaster on one-sided and two-sided are evaluated according to the burning time and the highest temperature reached on the unexposed side. The pre-testing result shows that the chipped and cracked mortar conditions affect the high temperature of the specimen and the burning of the woven bamboo, and vice versa. In the standardized test in the second stage, it was found that the specimen with one-sided mortar had an insulation and integration level of 30 minutes, while the specimen with two-sided mortar was 120 minutes. These results indicate that the mortar condition and its location affect the fire resistance performance of the bamboo-plaster wall.

Abstract: Forest destruction in Indonesia reaches 3,800,000 ha per year, most of which are illegal logging. Construction contributes to the use of wood as a construction material, inefficiency in the use of wood as construction waste, especially in high-quality wood species with a long harvest life. Indonesia's total sawn timber production reaches 1.4 million m3 per year of strong wood types. Utilization of this wood can result in environmental damage. Therefore, efforts to use construction materials that are more environmentally friendly have been encouraged to develop. Including short-lived wood (five-year harvest period) or used wood materials (reuse/recycle). In order to increase the efficiency of material utilization and reduce waste, namely by using a modular prefabrication method. This paper will identify green performance on the â€œMaterial Resources and Cycle (MRC)â€ criteria.

Aims: This study aims to analyze experimental approaches used to evaluate the thermal insulation performance of bio-based wall materials derived from agro-industrial waste, with a specific focus on Palm Oil Fuel Ash (POFA) and eggshell powder, in the context of sustainable tropical building applications. Methodology and results: This study employed a Systematic Literature Review (SLR) consisting of three primary stages: a comprehensive search across reputable databases (Scopus, ScienceDirect, and Google Scholar), article selection based on predefined inclusion criteria, and thematic analysis of 78 eligible studies. The review focused on experimental methods for evaluating thermal performance, including thermal conductivity (Hot Disk, Guarded Hot Plate), specific heat capacity (DSC), surface reflectance (UV-VIS), and chemical-microstructural analyses (TGA, SEM-EDS, XRD). Findings indicate that POFA and eggshell powder exhibit thermal conductivity values between 0.12–0.25 W/m·K, attributed to microporous structures and high SiO₂ or CaCO₃ content. Nonetheless, the integration of these laboratory findings with building energy simulations and the consideration of tropical, specific variables, such as humidity and solar radiation, remains notably limited in existing literature. Conclusion, significance and impact study: This study identifies critical methodological gaps in current research on bio-based thermal insulation materials and underscores the need for a more integrated evaluation framework. Specifically, it recommends combining laboratory testing with building energy simulation to enhance the validity and applicability of findings. Such an approach is essential for advancing the reliable implementation of agro-industrial bio-waste materials, such as POFA and eggshell powder, in sustainable tropical architecture. The proposed integration not only strengthens the scientific foundation of material performance assessment but also contributes to more climate-responsive and low-carbon building design strategies in the Global South.

This study investigates street network connectivity in an informal settlement, Kampong Taman Sari, Bandung. It generally refers to the informal residential area with minimum facilities and urban services. The majority of these settlements depict irregular patterns and narrow paths or alleys. Thus, kampong inhabitants mainly rely on walking, biking, and riding motorcycles to access vital urban features and functions. This purpose study is to examine the potential connectivity not only for accessibility but also for evacuation movement in an informal settlement. This investigation also aims to understand an associative relation between street-network configuration and informal settlement patterns with the probability distribution of pedestrian movement. This study utilizes computational street network analysis through the space syntax method that consists of two distinctive evaluations, such as axial analysis and visual graph analysis. The following result depicts the spatial accessibility, integration, permeability, walkability, and connectivity based on this relation. Experimenting in modelling a walkable kampong in the urban environment will conduce to urban design qualities of the street environment and street network layout for pedestrians or users.
