Abstract
A courtyard is a main architectural component commonly found in the Chinese traditional shop houses, which was introduced by the Chinese traders. Although many studies have been done previously regarding the courtyard design, not many types of research have been done on the community buildings on the east coast of Peninsular Malaysia, especially in Kota Bharu, Kelantan. Moreover, not much information to be found towards suitable methods on the courtyards’ elements modification and its impacts. Hence the purpose of this study was to examine and discuss new added values towards these heritage shop houses courtyards components alteration within the city of Kota Bharu, Kelantan, Malaysia, without changing its purpose and benefits. The research employed a qualitative method through visual observation and in-depth interviews within its building occupants as well as experts to seek their perceptions. The early findings demonstrated the courtyards had their own uniqueness in cultural aesthetics and functions. By adding certain new values such as glass roof windows, planting, water elements, and modern materials, it can provide better internal environment satisfaction to its building and occupants. However, these added values must be well planned and controlled so that they do not harm the heritage values.

Abstract
The development of the UPI Purwakarta campus cannot be separated from the history of the campus which is marked by the existence of heritage buildings with colonial architecture. Amid building developments in the current millennial era, the UPI Purwakarta campus as one of the leading educational buildings in Purwakarta does not yet have a distinctive image or identity in each of its buildings, even most of them are still like simple buildings. Therefore, this paper will examine campus architecture which can represent contextual campus buildings and identity through facades. The research method used is descriptive qualitative with a historical approach. The results of this study indicate that the campus building design adopts the acculturation of Sundanese traditional architecture that appears on the roof, namely the “jolopong” roof, combined with the colonial architecture that appears on vertical, horizontal, and curved lines. In addition, the colonial facade is formed from a protruding line of columns and beams. The results of the study in this paper expected to be used as a guide in the construction of further campus buildings.

Published: April 2021

AbstractThe quality of the urban environment is one of the important aspects to be researched in a developing country. The city of Bandung is growing and expanding beyond capacities without a city plan. This has led to the emergence of many urban village. The growth of urban village with lower middle economic level causes these settlements to have low environmental quality. Tamansari is one part of the urban environment that experiences this phenomenon, which is triggered by the large number of residential employees and students.The purpose of this study was to determine the environmental quality of the urban village (Kampong Tamansari) based on walkability. The method used in this research is a quantitative approach using Urban Network Analysis, a toolbox from ArcGIS that can quantitatively measure how the design of an environment affects access to spatial and amenitic spaces and contributes to the flow of pedestrian movements in urban area. From here, five types of network centrality measures will be formulated on a spatial network including Reach, Gravity Index, Betweenness, Closeness and Straightness. The results show that the Tamansari area in the south of the Pasopati Flyover is more walkable than in the northern part. The northern part is more difficult to access due to the lack of openness of the area’s road network to the main roads.

Abstract
Because of their structure, urban areas induce very complex climate phenomena while notably impacting pedestrian safety and comfort in the urban microclimate. This paper presents the results of an investigation into the influence of urban block typology and building intensity on environmental performance in the context of the urban microclimate of a hot-humid high-density city. Qualitative and quantitative characterization of the building geometries used in this study was conducted to compare an existing block typology scenario with five new block typology scenarios in an area of 350 x 350 x 150 (L x W x H) meters. The scenarios investigated were composed of different settings for floor area ratio (FAR) and building coverage ratio (BCR) and different configurations of building elements (tower, podium, and courtyard). They were simulated and analyzed using the ENVI-met software. The simulation results indicate that the five new scenarios all improved the environmental thermal parameters and that the FAR has a greater influence than the BCR. FAR has the strongest correlation with air temperature, followed by solar radiation and relative humidity. The influence of BCR on humidity and wind speed is not as significant as that of FAR. A tower strongly influences wind speed in proportion to the height of the building. Open courtyards correlate with higher temperature and lower humidity than closed courtyards. The combination of a closed courtyard with a hybrid block consistently outperformed the other configurations in thermal performance. Within this framework, the proposed scenarios can provide recommendations for city design regulations and input for urban design methods to further improve microclimate performance.

Authors: Wardhani Dyah Kusuma , Susan Susan 
Published: April 2021

Abstract
Greenship Interior Space (IS) is a set of criteria established by the Green Building Council Indonesia (GBCI) as a rating tool for assessing the interior space of a building. It is mainly used as a guideline that needs to be applied to buildings in order to achieve more sustainable design through energy and resource savings. Hence, it is expected to reduce the building operational costs, improve the users’ health and comfort, as well as to leave the minimum carbon footprint. Greenship IS rating tools consist of several categories, i.e., Appropriate Site Development (ESD), Energy Efficiency and Conservation (EEC), Water Conservation (WAC), Material and Resources Cycle, Building and Environment Management (BEM), and Indoor Health and Comfort (IHC). As the COVID-19 virus pandemic continues to spread, these categories need to be reviewed. Therefore, green building is not merely for sustainability but also expected could reduce the transmission of the Coronavirus that causes the COVID-19. This disease is transmitted through direct or indirect contact with the subject, droplets, and aerosols. This research employed a literature study of Greenship IS adaptation regarding the pandemic situation and followed by the critical analysis that focused on the proposed strategies for the criteria by investigating the cause, prevention, transmission, and impact to the interior space. The adaptation of Greenship IS shows the importance of human health must be achieved apart from the sustainability aspect. From the literature review, it can be concluded that the adaptation of Greenship IS is focused on creating good indoor air quality, appropriate material selection, access to nature for the occupants, maintaining health protocol, and regular disinfection in managing the building to reduce the COVID-19 transmission.

Abstract
A jib crane is a type of lifting equipment that is commonly attached to the walls of factory buildings to raise or lower a load. The lifting mechanism can rotate with a turning angle of 180 degrees. A trolley hoist can be moved manually by chain drive. This research aimed to optimize the design of several variations of the jib crane structure of load lifters that meet the criteria of optimizing safety factor. Firstly, the design concept was made by varying the main beam of the I Beam 300. Then calculated analytically. The 2D and 3D geometry were made in four variants of JC-1, JC-2, JC-3, and JC-4. The strength of the main beam structure and others was analyzed using FEM software. The load of the crane was 24500 N, a range radius of 3 meters, and a turning angle of 180 degrees. The best results were obtained by comparing the yield stress to the maximum stresses that occurred according to Von Mises. Based on the simulation results, the best design is the JC-4 variant. Variant JC-4 simulation results show that the safety factor closed to the optimum point.

Published: April 2021

Abstract
Materials with nanoscale particle size have different properties from its bulk phase, which allows for wider application of the material. There are various methods to synthesize nanoparticles, namely physical, chemical, and biological method. Nowadays, nanoparticle synthesis method is focused on biological method because of its advantages, such as environmentally friendly, relatively simple procedures, and lower production costs. Biosynthesis by co-precipitation method using extracts from biological agents is considered the most efficient among other biological methods. Biochemical compound in the extract have a dual role in synthesis, they act as a reducing agent which reduces metal salt to metal ion, and as a capping agent which stabilizes the nanoparticle. Biosynthesis has been shown to result in nanoparticles as good as physical and chemical method. However, several studies report that the synthesized nanoparticles have low stability regardless of the presence of their capping agent, resulting in agglomeration of nanoparticles, which reduces its efficiency. Until now, studies on particle deagglomeration especially during nanoparticle biosynthesis have not been widely carried out. This mini review will explain the phenomenon of agglomeration during biosynthesis. Moreover, deagglomeration treatment using physical and chemical approaches will be examined. Each approach is considered to be able to deagglomerate nanoparticles well, and the combination of the two is projected to be able to provide better results.

Abstract
Microbial fuel cells (MFCs) are devices that utilize the work of microorganisms to oxidize organic substrate involving biochemical pathways. Several studies have been done based on experiments while simulation and modelling remain unexplored. Basically, MFCs have a lot of similarities to chemical fuel cell systems, which modelling and simulation have been widely developed. Hence, a study should be done to develop the model in order to widen the implementation of MFCs. In order to evaluate MFCs performance with less cost and time, numerical modelling might be an effective approach. Models could also be easily developed or modified for various operation conditions and configurations to generate experimental data on MFCs. A number of papers on simulation and modelling focused on cell voltage as function of both cell current density and chemicals concentration. In this paper, a double chamber acetate MFCs under continuous operation and unsteady state condition would be investigated. MFCs model based are developed by calculating biochemical reactions, Butler-Volmer equation, and electrochemical equations using MATLAB 2018a software. The parameters and constants data reported from recent literature are used. Results show that periodic flow rate of fuel could improve the power production. This result also gives the prediction of cell voltage and current density. Nevertheless, models with various conditions or configurations could be developed to scale-up or create more efficient MFCs using simple methods.

Published: April 2021

Abstract
The global demand for fossil fuels has increased sharply in the past 50 years. Plant biomass is one of the fourth largest non-fossil renewable energy sources after geothermal, solar, and wind energy. Biomass can be first converted into another energy form, such as ethanol, to provide a more efficient energy source. Syngas fermentation enables converting all biomass components, including lignin, into ethanol, thereby increasing the biomass quantity. The development of the syngas fermentation process will be reviewed in this article, which focuses on the types of microorganisms used, the effect of syngas composition, and the gas-liquid mass transfer to be used as a reference for optimizing the syngas fermentation process.

Published: April 2021

Abstract
Lately, the increase in biofuel production has simultaneously led to lignocellulose material disposal activities. As a waste produced by the biofuel industry, lignocellulose materials are not utilized fully yet due to their complex polymeric structure. As one compound of lignocellulose, lignin possesses the lowest economic value due to its recalcitrant nature. In this work, guaiacol as one of monomeric substance originated from lignin is used as a representative molecule to be valorized due to the existence of both hydroxyl and methoxy moiety groups in it. One important reaction of lignin monomeric substance (phenolic compounds) valorization is oxygen removal. Aromatic substances such as Benzene and Toluene are produced through oxygen removal from the guaiacol molecule. Hydrodeoxygenation of guaiacol is aimed to remove oxygen atoms from it. Though conventionally hydrogen for the Hydrodeoxygenation process is supplied by external molecular hydrogen, in this work it is supplied from hydrogen atom abstraction of methylcyclohexane. Therefore, in a one-pot catalytic reaction system, methylcyclohexane dehydrogenation is the sole hydrogen provider for subsequent hydrodeoxygenation of guaiacol and this novel concept of a circular hydrogen economy has been proven its feasibility through heterogeneous catalytic reaction schemes conducted in this work. Metal supported on zeolite beta is selected as heterogeneous catalysts to evaluate the feasibility of one-pot hydrodeoxygenation and dehydrogenation reaction. Of every catalytic reaction attempt, multiple products consist of alkylated phenol, phenol itself, and toluene are observed proofing the feasibility of this concept. Possible interaction of catalyst surface acidity and metal contents are also probed through the distribution of byproducts. Overall, sequential dehydrogenation and hydrodeoxygenation have been proven through a catalytic reaction catalyzed by metal-supported zeolite beta catalyst and this work can potentially pave the way for further application.
