    Perceived Neighborhood Walkability and Walking for Particular Purposes among Motorcyclists in Bandung City, Indonesia

    Authors: Romeiza Syafriharti, Kambaitan B, Ibnu Syabri, Puspita Dirgahayani

    Abstract

    This research was conducted to predict the effect of perceived walkability on walking behaviour among motorbike users in Bandung, for a specific purpose. The walkability factors tested are safety, security, and convenience. Meanwhile, the specific purpose when doing walking activities is walking for transport and walking for leisure. Binary logistic regression was used to analyse the effect of walkability on walking behaviour. From the results obtained, there is a difference in the effect of perceived walkability on the behaviour of walking for transport and walking for leisure. In addition, there are also differences in the effect of walkability on gender and age groups. The walkability factor that most influences the walking behaviour of people who usually use motorbikes is security and convenience. Although statistically, the effect of walkability is small on the walking behaviour of people who usually use motorbikes, the results are significant. These results show that walkability in the neighbourhood cannot be ignored. © School of Engineering, Taylor’s University

    Authors: Andi Harapan Siregar

    Abstract

    Traditional house in Panjalin Village is one of the Sundanese vernacular houses, houses that adopt the shape of Sundanese traditional houses. Many Sundanese traditional houses are found in Pangandaran and Tasikmalaya. Field observation conducted after the earthquake hit in 2007 and 2009 showed that those houses are more resistant than concrete-made houses. Sundanese traditional house in Panjalin Village is earthquake-related strength, Indonesian National Standard (SNI) earthquake zoning, and soil types. The studied area is categorized in Zone III in SNI earthquake zoning and has a hard-soil. This study method used qualitative and quantitative to get the data and conduct the analysis. Qualitative was conducted by discussing and taking photos of the traditional houses, and quantitative was conducted with measurement and modeling using the software. The modeling (with software) was conducted to beam and column of traditional houses to know its strength and moment, as the inputs to the whole force and shear force. The SAP 2000 ver. 14 (software) is used to conduct simulation tests to know traditional houses in Panjalin Village strength related to its categorized area and soil type. The purpose of this paper will be an input for local people who stay in an earthquake-prone area, to know (as a lesson learn) about the strength of their traditional house related to the earthquake. The conclusion is the traditional houses that built without an engineer and had adapted several times to nature behavior – in this case, is an earthquake – are tested by a computer program that is scientifically and rationally earthquake-proof. © School of Engineering, Taylor’s University

  • Nata De Coco Material Monitoring System Using Internet of Things

    Nata De Coco Material Monitoring System Using Internet of Things

    Authors: Bobi Kurniawan, Haq A. H, Alvian Sopian 

    Abstract

    The purpose of this research is to create a monitoring system for the solution-mixing process used to manufacture Nata de Coco using the Internet of Things. Nata de Coco’s manufacturing process usually mixes coconut water solution with vinegar and seed solution. The mixing process is usually used with manual measurement. In the mixing process, the makers usually only measure the amount of the solution mixture regardless of the final result and the effect of temperature and acidity levels for the ingredients. This can lead to the failure of the mixing process for the Nata de Coco solution. Therefore, in order for the mixing process to be controlled and to improve the quality and success rate of the mixture, it takes a system that can monitor the mixing process and the result of mixing the manufacture of Nata de Coco. The method used in the creation of this monitoring system refers to the prototype method with the stages of communication, quick planning, model design, prototype building, and system usage. The result of this study is a system that can perform the process of mixing Nata de Coco material solution that can be monitored in realtime in order to produce an excellent product with a good acidity level that is with a value of 3.5 to 7.5. With a good acidity value, it can produce good quality Nata De Coco. © School of Engineering, Taylor’s University.

    Potential Agricultural Land Suitability Visualization Using Augmented Reality Geographic Information System (AR-GIS)

    Authors: Hanhan Maulana, Hideaki Kanai

    Abstract

    This study aims to visualize the potential agricultural land suitability using the Augmented Reality Geographical Information System (AR-GIS). AR-GIS can provide an immersive experience to users. Bandung Regency area was chosen as the study area because it has good potential for agriculture. The challenge that motivates the development of Augmented reality in the visualization of Land Suitability is that farmers can use GIS practically to assist in decision making. This study has three main stages. The first and second stages integrated the MultiCriteria Decision Analysis (MCDA) with the Geographic Information System (GIS) method. The first stage aims to determine potential commodities using the MCDA method by considering economic, environmental, and plant characteristics factors. The second stage describes the land suitability evaluation process for each commodity using the GIS method. Based on the evaluation results, cabbage, potatoes, and onion are the most suitable plant to be cultivated in the study area. This result is consistent with statistical data that shows that these commodities have the highest productivity. The third stage of this study explains the process of map visualization using augmented reality. AR-GIS is expected to be able to provide a better map visualization display. With good map visualization, information on the GIS can be easy to understand by the user. Furthermore, it is hoped that the AR-GIS will have a high level of usability. © School of Engineering, Taylor’s University.

  • Corn Sheller Machine Technology to Improve Farmers’ Productivity

    Corn Sheller Machine Technology to Improve Farmers’ Productivity

    Authors: Senny Luckyardi, Raiswati Untsa Mega, Kevin R, Naufal A. N, Hanifah A. P

    Abstract

    Corn is an essential requirement for human life and is the second food-crop commodity after rice. Therefore, this research aims to design a corn seed separator machine using a cheap and lightweight engine with little driving force. This study used simple calculations for getting the optimal design of the corn sheller machine. The separator machine is by cutting the material, working on machinery, welding the frame, installing and assembling the machine after it is repaired and tuned. The next step is testing the performance of the device by checking the capacity of the shelling. If there is damage, it will be repaired again, but if not, then the machine is ready to use. The results of quality testing and production capacity show that the difference in shelled corn diameter affects the shelled production capacity, where the more significant the shelled corn diameter, the higher the production capacity. The design of this corn machine sheller is estimated to increase the amount of processed corn seed production by 20% of the product using a mechanical device on the market, with an electrical power of 0.8952 kW (estimated 1 hp 0.746 kW). Functional design and how the machine works, namely using oil-fuelled energy, are two sorting levels: coarse and fine. © School of Engineering, Taylor’s University.

    Authors: Muhammad Rizky Firdaus, Budi Herdiana, Rio Muhammad Iskandar

    Abstract

    Dipole antennas are quite popular in various research in the field of antenna technology. Many models and modifications have been made to obtain optimal performance according to the application field. Of the many models of this antenna, it turns out that not many of this type of antenna has the same function as a transmitting and receiving antenna. Therefore, the aim to be achieved in this research is to model a half-wavelength open UHF dipole antenna to work well on UHF broadcast frequency allocation. The method to realize this is using a comparative test approach, which begins with designing a physical model of the antenna, then it is tested by an antenna plotter detector automatically, the result is a visualization of the shape of the antenna radiation pattern. From this radiation pattern, the gain angle area, transmit power, receiving power, and Return Loss will be seen. Based on the test results, the maximum transmit power of each antenna is 121 mWatt and the received power is 97 mWatt with a return loss value of -18.78 dB at the broadcast UHF frequency of 428.5 MHz. © School of Engineering, Taylor’s University.

  • Improving the Performance of Laston AC-WC Padding with the Utilization of Nickel Slag Waste

    Improving the Performance of Laston AC-WC Padding with the Utilization of Nickel Slag Waste

    Authors: Falderika, Nur Fitrah

    Abstract

    Utilization of waste as part of the road pavement material is an important issue. This is caused by the decreasing availability of natural materials as road raw materials and the increasing costs for procurement as well as the process of obtaining aggregates. As a result, alternative materials are needed and one of them is nickel slag. Nickel slag is categorized as Toxic and Hazardous waste (B3), so testing is needed to determine the content of the hazardous substances. The value of the Toxicity Characteristic Leaching Procedure (TCLP) test is smaller and meets the requirements, the results of testing the physical characteristics of nickel slag also meet the requirements used in road construction materials. The purpose of this study is to analyse the effect of using nickel slag on the performance of the Laston mixture (AC-WC). The tests were carried out based on the empirical method with the Marshall test which refers to the provisions of the properties of the Laston mixture (AC-WC) General Specifications for Roads and Bridges of Highways, Bina Marga, 2018. Variations in Reference Asphalt Content (KAA) used are 5%, 5.5%, 6%, 6.5%, and 7%. Based on the analysis results of the Marshall test, it is known that the use of nickel slag has better performance in terms of the higher Marshall stability value of 1803 kg compared to 1660 kg in a mixture without nickel slag. From the results of the tests and analyses carried out this nickel slag waste can be used as a new material in the asphalt mixture so that the impact is that the waste can be reused. © School of Engineering, Taylor’s University.

  • Designing Collaborative Augmented Reality Geographic Information System for Land Suitability Visualization

    Designing Collaborative Augmented Reality Geographic Information System for Land Suitability Visualization

    Authors: Hanhan Maulana, Kanai H

    Abstract

    This study aims to visualize the potential agricultural land suitability using the Collaborative Augmented Reality Geographical Information System (AR-GIS). In agriculture decision-making, geographical aspect is one of the important factors to be considered. However, there are plenty of limitation in the early AR platform and one of which is the limitation on the number of users. Cloud-based anchor points are able to overcome this limitation by connecting multiple users via the internet which allows them to see, interact, and synchronize a digital context simultaneously. Through this technology, this research was divided into two stages. The first stage is to make a land suitability map. The second stage is the development of Collaborative AR GIS by adopting a user-centred design approach. This study integrates GIS with AR visualization capabilities to visualize land suitability maps then enable multi-user collaboration work based on AR Object. This study developed an AR-GIS-based system using UNITY 3D. The built AR GIS was based on multi-platform to overcome the various mobile device platforms used by farmers which then integrated with Cloud anchors to connect one device to another. Cloud anchors enable collaborative work between farmers and other stakeholders. This study evaluates the system performance using two devices that have different specifications. Based on the evaluation result, good maps visualization is able to be provided by the collaborative AR-GIS. The collaborative AR technology also gives an alternative visualization as well as alternative interaction with maps that have multiple users. This system is envisioned to improve the understanding of farmers towards land suitability map. It is expected that the collaborative AR-GIS system is able to provide a helpful aid to the farmers in terms of decision-making. With well-informed decision and insight on land suitability map, the risk of crop failure can be minimised, and the agricultural sector’s productivity can be increased. © 2023 Taylor’s University.
