Published: November 2021

Ever increasing usage of fossil fuels and dwindling natural resources led researchers to concentrate on investigating other sources which can satisfy our demands and reduce pollution levels. Present research work aims to investigate the performance and emission characteristics of plastic, diesel and biogas as fuel blend operated in a dual-fuel engine with biogas as a primary fuel and plastic oil – diesel blends as secondary fuel and also predict the output variable using artificial neural network. A modified four-stroke single cylinder CI engine was used for experiments conducted at varying load, percentage of plastic oil percentage in diesel and biogas flow rate. Based on the levels and factors a Taguchi L9 orthogonal matrix was designed to find the optimal combination of input indices. The signal to noise ratios in taguchi method were applied based on the desired output characteristics and according to the respective SNR ratios an ANOVA table was created to determine the major contributor effecting output parameters such as brake thermal efficiency, CO, HC NOx and smoke emissions. ANN model helped to predict BTE with same input parameters but with an increased set of sample data. Based on Gradient descent and Levenberg-Marquardt algorithm the ANN architecture was trained, validated and tested to predict the response with least error. The ANOVA calculated indicates load to be the prime factor effecting BTE and NOx emission

Published: November 2021

The dynamic behaviour of the straight–type Darrieus turbine with leading-edge protuberance (LEP) was analysed under various solidity ratios at several tip speed ratios through experiments. The Darrieus turbine is a type of Vertical Axis Wind Turbine (VAWT) which uses wind energy to generate electricity. This type of turbine was subjected to vortex-induced and buffeting types of vibrations. These vibrations were more sensitive to the number of blades and tip speed ratios. Based on the experimental measurements, the results revealed that, at a low tip speed ratio, the four-bladed turbine exhibits lesser vortex-induced vibrations than those of the three and five-bladed turbines. However, at a high tip speed ratio, the three-bladed configuration operates well against the vortex-induced vibrations. In the case of buffeting, a three-bladed turbine diminishes the dynamic oscillations at both low and high tip speed ratios, whereas the four and five-bladed turbines induce dynamic oscillations at slightly higher amplitudes. However, the amplitude of buffeting is smaller than those of vortex-induced vibrations.

Published: November 2021

Currently the industrial heat demand is met by using expensive fossil fuels. Exclusive use of solar energy is not feasible due to the fluctuating pattern of solar radiation intensity. Solar hybridization with the existing heating system can be an appropriate solution to meet the process heat requirement of many industries. Concentrator Solar Thermal (CST) technologies can generate the medium temperature heat required for industrial processes. The present study was undertaken with an objective of comparing and analyzing the designed performance of the solar fields using the Compound Parabolic Concentrator (CPC) technology against the actual measured performance values for boiler feed water preheating application at two different locations in India. The optical efficiency of the CPC collector, 64.8%, obtained when tested as per part 5 of IS 16648:2017 was used for designing the solar fields as per the daily heat requirement. The performance of the installations at both the locations was monitored for a period of five months. The observed variation in the performance of each installation than the designed performance was compared and analyzed for the causes. The average variation in designed and measured performance was in the range of 9.0% to 9.8% for location 1 and 2 respectively, attributing to heat rejection from the collector attachments and fluid transfer lines, dust effect on the absorber and reflector of CPC, instrument’s uncertainty, other losses due to shadow effect, vacuum loss from the tubes, dislocation of tubes, heat removal and usage pattern etc. The reasons of the losses from both the fields were of the similar nature, which should be taken into account to design a solar thermal system to achieve predicted performance near to the designed performance. Preheating of boiler feed water is one of the potential applications of solar CPC technology.

Published: November 2021

The architect’s profession is very close to things related to design. The face of the metropolis, which is now entering the modern era, contrasts with the faces of lower strata towns that are unable to catch up. Because of this, local governments in Indonesia have launched several initiatives to improve settlements by including architects in the planning process. According to a case study completed in Semarang, one of the government’s efforts to improve settlements is the Kampung Tematik program. This program provides new collaboration between architect organizations, governments, and communities. In performance, the architect serves many clients, and there are several design negotiations. However, due to the large number of people engaged and the time constraint, the design eventually gained concept dispersion. What was envisioned or planned is not synonymous with what was constructed or implemented. This study aims to examine how architects engage with several clients during the Kampung Tematik program’s phases and have to deal with the design and build phase. Architects who work with the community need special skills to communicate with many clients. The concept of the collective agreement may be realized not just as an architect’s work but also as a collaborative all actors thought.

Recent studies demonstrate that the Covid-19 pandemic is a health and daily life crisis unmatched in human history. Restrictions on the exercise of social distancing and using innovative technology to virtually hold gathering have been the key policy measures to reduce the transmission of Covid-19 and to protect public health. International health organisations and governments precautionary measures for their people advise for physical distancing, total lockdown, and handwashing hygiene measures. Social distancing has redefined, reshaped, and reconfigured Straits Chinese families’ gatherings in a shophouse courtyard space. Hence, this paper bids to investigate the effectiveness and efficiency of these mechanisms by inhabitants and visitors in shophouses courtyard space and suggest possible ways to lessen future Covid-19, particularly concerning interior design components of a typical shophouse courtyard space. Thus, the paper adopts the phenomenology type of qualitative research. Data were collected via observations of selected traditional shophouses in George Town Heritage City, face-to-face interviews conducted and validated via secondary sources. Findings show that it is difficult to practice some of the precautionary measures as recommended by appropriate authorities in majority of the George Town Heritage City traditional shophouses. This is because of compact space, also renovation, and modernisation to the courtyard original design. Concerning the practical implications, this research is encouraging for the practice of social distancing on Straits Chinese gathering at shophouse courtyard space during pandemics such as Covid-19 to lessen the contagious pandemic spread in shophouses families in the future. This research further intends to trigger key stakeholders and conquer new areas for forthcoming study.

Assessing cooling energy of insulated building built in tropical country
Authors: Sigalingging R C P
Published: November 2021

Global warming is a huge issue and has become a global concern lately. The global warming issue is gaining more attention on reducing fossil energy since fossil energy has significantly exacerbated global warming. Since housing sectors are consuming significant fossil fuel energy, reducing housing energy consumption is necessary. One option discussed in this paper is to reduce the load on the air conditioner (AC) by applying insulation to the building. Reducing the AC energy will reduce the total energy consumption in the buildings. Building practice in a mild climate has shown that good insulation can reduce heating or cooling energy in the building. But using insulation in housing is not a common practice in Indonesia’s construction sectors. Simulating the use of insulation in housing will show how much energy reduction will be obtained, especially for air conditioning energy. The analysis in this study found that thermal comfort is related to air temperature and relative humidity in the room. This article will study the reliability of using insulation in buildings to reduce energy consumption and provide thermal comfort for the occupant.

Patented in the 1880s and having a longstanding industrial history, expanded metal sheet has a remarkable reputation for its application. However, despite the benefits of its use and numerous studies has been conducted on window shading and its daylight evaluation, research on extended metal shading’s daylight performance is still limited. This paper investigates the role of expanded metal shading to assess Daylight Glare Possibility (DGP) in Shimonoseki, Yamaguchi, Japan, utilizing parametric design approach and Multi-Objective Optimization (MOO). The simulation and analysis were undertaken to determine how expanded metal can optimize DGP, the significance of improvement, the relationship between the View (aperture) and the DGP, and which parameters have the most influence in driving the aperture size and the DGP value. Analyzing 2322 solutions and 88 Pareto frontiers resulted from the MOO, several findings has been portrayed. Firstly, the shading View (aperture) shows a significant positive correlation to the DGP. Secondly, parameter Strand/W was identified as the most influential parameter that drive the objectives. Thirdly, the validation process portrays optimization in DGP by 38%. The results of the proposed methodology are expected to become an immediate geometry and performance feedback for designers and industries, supporting design decision-making processes during early design phase.

Authors: Utami K S , Wulandari E , Dewi C
Published: November 2021

One of the important factors in supporting the sustainability of an architectural design is the ability to adapt to the environment. This adaptation can be observed, among others, from the accommodative level obtained from a building design to the needs of the community that uses the design. One form of design that is considered to accommodate the needs of the user community is the design of a floating system used by fishing communities. This paper wants to explore the adaptability of the floating system design which is judged by its ability to accommodate the dynamics of the wet environment and the needs of the fishing community. The research method is descriptive and logically explains the causal relationship between the design of the floating system building and the environmental and socio-cultural aspects of the community. Observations show 2 things: a) the legged building system (pit foundation and 2 meter stilt building) is highly adaptive to wetland conditions with tidal characteristics of water at the mouth of the river; b) architectural design of residential units which are about 4 meters apart, allowing the development of residential units into 4 sides, to accommodate the increase in daily activities of fishing communities so that community productivity increases. The conclusion of the study shows that the floating system is very flexible and adaptive to the dynamics of the environment and people’s lives (socio-cultural and economic aspects).

A healthy house is a building used to protect humans from climate disturbances, bacteria, and other hazards for human health. A healthy and safe home is necessary to meet human needs both physically, mentally, and socially. A healthy home is also a way to protect ourselves from the current pandemic of Covid-19. Aceh is one of the provinces in Indonesia which has a rising number of infections. This research is a preliminary study to evaluate the home performance, including its environment in Aceh, which utilizes the quantitative method of collecting data through a survey. The evaluation parameters are referred to the healthy house standards from the Indonesian Ministry of Health. The data collection was done conveniently to 14 houses located across Aceh. The study shows that among the surveyed house, one house (7.1%) is good, six houses (42.8%) are moderate, seven houses (50%) are bad. The number of the survey is small; however, it can be a start to figure out the quality of houses in Aceh based on the healthy home standard. This study also indicates that the ventilation for providing air circulation and daylight is the poorest. While, actually an excellent ventilation will outlast the pandemic due to the increase of the infiltration rate that will reduce the trapped virus, odors, and other contaminants.

One of the city government’s programs to upgrade the representation of Banda Aceh as a green city was to revitalize the open space of krueng Aceh riverbanks. However, such a work has been progressing slowly. Although some wide banks area have been processed into parks, but, some other areas especially those with narrow areas in sizes of the banks have not been upgraded. Currently, these areas, with less green, have been becoming slum where some illegal settlements occurred. In general, the area along Aceh riverbanks has not been design comprehensively, since there has insecure public accessibility, irregular park zoning, un functioned water tourism facilities, un proper waste management system, and un balanced socio-economic conditions in relation to local environmental conditions. The purpose of this study is to identify the characteristics of green open space at the Krueng Aceh riverbanks, Banda Aceh City and formulate criteria for structuring Green Open Spaces based on Sustainable Urban Riverfront. This research uses descriptive qualitative research method. The research instrument used was interviews, field observations, literature studies. Data analysis was carried out in a qualitative descriptive manner with data reduction analysis techniques, data presentation and conclusion. The results of this study are the design recommendations for Green Open Space (GOS) that apply the principles of sustainable urban riverfront. The development of the potential of the Krueng Aceh riverbank as a green open space is expected to be a sustainable landscape and able to support the function of the area from the ecological, social, and economic aspects.

Rumoh Aceh as a building has the value of sustainability and environmentally friendly, and also loaded with the values of local wisdom that exist in the lives of Acehnese people. Rumoh Aceh in its development has undergone various adjustment processes to the environment so that it can survive until now. But along with the development of modern era that demands efficiency and the fact of increasingly difficult to find good quality wood materials for the manufacture and maintenance of traditional architecture of Rumoh Aceh, then gradually fewer people build and maintain Rumoh Aceh. Although constrained in the difficulty of procurement of good quality wood materials and maintenance, the existence of Rumoh Aceh must be maintained. Therefore, this research needs to be done as an effort to understand the constraints of the availability of good quality wood materials for the manufacture and maintenance of traditional architecture of Rumoh Aceh and find alternative solutions that are environmentally friendly to support the preservation efforts of Rumoh Aceh. This qualitative descriptive research uses variety of primary and secondary data of traditional architecture of Rumoh Aceh. The results of this study revealed the use of green structures and technologies as well as environmentally friendly engineering wood materials can be one of the alternative solutions in preserving the traditional architecture of Rumoh Aceh.

Dwelling as an alternative to cure and isolate confirmed positive or asymptomatic people of COVID-19 becomes an essential place. However, it is necessary to ensure no physical contact between dwelling users since COVID-19 can be transmitted through droplets. Preventing and controlling the transmission is achieved by inserting transitional space between users, activities, or programs. The idea of transitional space is determined from Rumoh Aceh, an adaptive vernacular design that provides a boundary between public and private zones to limit access to strangers. This paper aims to translate space configurations of Rumoh Aceh as local wisdom to break the chain of COVID-19 transmission by making transitional space, a separation between confirmed positive or asymptomatic and healthy people. The data is obtained from the observation of three Rumoh Aceh in Banda Aceh and Aceh Besar. The space configurations are translated into five types of threshold space, promoting social distancing between users, providing cleaning space for personal hygiene, giving atmosphere for self-isolation, having natural ventilation features, and daylight exposure. Then, these types are explored and adapted in a contemporary dwelling design. As a final translation and exploration, this paper provides strategies and design recommendations for a threshold space in a contemporary dwelling design. The strategies and recommendations are explored and adapted in a 60 square meter house plan.

One of the most efficient methods to optimize thermal performance in a building is the practical design of the façade. The double skin façade‘(DSF) is a crucial decision for handling the interaction between outdoor and indoor spaces. It also offers some spatial diversity in the design process. Recently, a lot of focus has been paid to it instead of the more traditionally glazed curtain wall. This is because of its potential to reduce energy effectively, achieve thermal comfort in the building, and save costs. The indoor spaces near to the glazed facades will become warm due to high incidence solar radiation on the East-West facades in Malaysia’s tropical environment. In the tropics, one of the solar heat gain reduction approaches is the use of double skin-facade (DSF). One of the fundamental components of the double-skin facade is the blinds. Blinds located in the cavity of the double-skinned facade and buffer the building from solar heat gain or perform the role of a pre-heater for ventilation air. In general, the temperature of the blinds is high, which is helpful in the cold period but problematic in the hot period. To minimize the cooling loads of the building, technological innovations for the shading system are considered. Plants can dissipate absorbed solar radiation into resistant and latent heat. Plants turn radiation into the latent heat. This paper aims to study the effectiveness of a double skin façade and explore improved innovative design for a double-skin façade design integrated with vertical green on research building to optimize thermal performance. This paper will collect data of the thermal performance of double skin façade, precedent study and run simulation analysis to achieve the aim of the paper.

Malaysia has a booming and successful fishery development. Fisheries Development Authority of Malaysia Complexes (LKIM) are located in every state of Malaysia to function as a fish landing jetty complex to allow fishing vessels for fish handling operations. However, the design and facility of Fish Landing Jetty Complexes in Malaysia are not up to date even though the fishery development contribute to Malaysia’s economy. Proper facilities and design strategies of fish landing jetty will ensure that fish handling operations work efficiently and enhance the fishery development in Malaysia. In this research, the design components and facilities of fish landing jetty complexes are studied for determining the design strategies of fish landing jetty complexes in Malaysia to enhance the efficiency of the building itself. In this research, a few precedent study and survey questionnaire had been conducted as a research methodology to review and compare the design components and facility of the precedent studies. Besides, the survey questionnaire is to collect the data and their opinion from the general public and users of the Fish Landing Jetty Complex to understand their satisfaction and expectation towards the current condition of the Fish Landing Jetty Complex in Malaysia. There are 41% of respondents are stated that majority of the Fish Landing Jetty Complexes in Malaysia are unsuccessful in achieving the efficiency of the fish landing process. The design strategies of Fish Landing Jetty Complex should consider on the working flow diagram of fish landing. Application of mechanical quay-side lifting winches, built-in conveyor system, rainwater harvesting system and solar energy able to increase the efficiency of the building. It is important to apply the commercial and public recreation spaces inside a Fish Landing Jetty Complex to sustain longer and produce revenue to the building.

The climates of countries in the tropics tend to have high temperatures and humidity, and intense solar insulation. This condition gives the impact of discomfort for humans who are in the building. Implementing a passive cooling strategy can reduce energy use. Traditional architecture is one of the buildings that has been believed to apply natural cooling as a passive cooling design strategy. Based on several previous studies on the application of passive designs to obtain thermal comfort in the room, this study was conducted to assess the thermal comfort of Modifying Rumoh Aceh, which has not been widely studied. This study uses a direct measurement method in the field using an anemometer to measure temperature and airflow velocity. An Infrared/Thermometer Gun is also used to measure the surface temperature of materials (walls, roofs, and floors). Using the Climate Consultant Software to obtain annual climate condition data, AndrewMarsh 3-D Sunpath was also used to assess the orientation of buildings. Measurements were carried out for 3 days on 15 samples of Modifying Rumoh Aceh in Gampong Jawa, Kutaraja sub-district, Banda Aceh. The results obtained indicate an increase in room temperature by 7ºC from the standard comfort temperature based on SNI. The human ability to adapt to the environment can be seen in the perception of the Gampong Jawa community in accepting changes in the thermal environment by 47% with a sense of satisfaction. However, further research is needed to obtain a value for the level of satisfaction of the thermal environment in the tropics area.
