Abstract

COVID-19 is a disease that has spread throughout the world and is transmitted through inhalation or contact with droplets of infected people. The Indonesian Government has established a health protocol to reduce the spread of COVID-19, which is checking the body temperature of visitors at public places. The officers' representatives from public places are mobilized to check the body temperature of the visitors by bringing the thermometer closer to the forehead or hand of the visitors. This paper aims to design a contactless thermometer using an Arduino Uno by adding an interactive design and light installation. It aims to enhance the user-experience rather the design idea itself. The thermometer will move a mechanical flower adjusted by the temperature measurement with this product design.

Abstract

This work focuses on the clustering in Wireless Body Area Network (WBAN). Recently, it was found that less attention was given to Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) clustering in WBAN. Past works on LoS clustering WBAN consider the problem of enhancing the network throughput and end-to-end delay of the network. However, the problem of necessary hop count for packet transmission has not been considered. The non-consideration of necessary nodes hop count degrades the performance of cluster-based WBAN as throughput of the network is reduced in addition to high end-to-end delay. This work develops a hop count aware WBAN for enhancing the performance of body nodes called improved Dual Sink Approach using Clustering in Body Area Network (iDSCB). The simulation results depicted that the hop distance criterion of iDCSB improved the performance of WBAN in terms of end-to-end delay and throughput by 3.16% and 6.59%, respectively.

Abstract

Brazil has a long tradition of bioethanol production from sugarcane. Following the Middle East crisis in the 1970s, the oil price increased twofold, doubling Brazil’s spending on oil imports. As a result, the country had to find an alternative type of fuel to reduce its expenditure on conventional petrol fuels. With its vast tropical land conditions, the Brazilian government then put massive effort to establish the infrastructure and research of bioethanol from 1975 and 1989. Research plays a pivotal role in the success of Brazil’s ethanol industry. The country was heavily criticised at the beginning of the programme, but today, Brazil is the second-largest ethanol producer after the USA. Brazil produces the cheapest ethanol in the world and does not depend on fossil fuel to supply its energy demand. Indonesia and Brazil share the same landscape and geographical advantages. This paper aims to discuss the success of the Brazilian bioethanol industry and draw important lessons from it. In a nutshell, Indonesia should increase bioethanol production from renewable sources. Also, the modernization of distilleries facilities, the establishment of new production plants, the introduction of subsidies and the reduction of taxes for ethanol producers are needed. In summary, apart from massive research and development, we concluded that effective and strong long-term government commitment play important role in shaping the future of the Indonesian bioethanol industry.

Abstract

Higher institutions run various programs. These programs must be authorized, in other words accredited by a National Institution for accreditation to ensure quality and standards. This research paper aims to provide a convenient way of accreditation for the various programs in universities or institutions of higher learning. The College of Engineering at the Kwame Nkrumah University of Science and Technology (KNUST) was used as a case study. Using the client-server model, a web-based, very flexible, and well secured accreditation management software was designed to address most of the challenges faced with manual accreditation process of the College of Engineering. The system provides a central database where all accreditation related information of the various programs is stored for easy access and modification by authorized personnel. A secured link and robust access control via authentication were implemented and a user management system was integrated. The system was tested and resulted encouraging outcomes, with some further works are recommended in the future to improve the features of the system.

Abstract

This paper examines the use of waste energy in a 3x1 MW Gas Engine Power Plant (GEPP) on Bawean Island, Indonesia. The feasibility method uses water-lithium bromide (H2O-LiBr) technology as absorption refrigeration technology. In addition, bananas are also used for cold storage to overcome waste energy utilization. The cold storage is placed in the 300 m3 area with a 100 kg load capacity for a banana with a temperature of 5oC, 85% humidity, 24 hours of operation, 1292 W cooling load, and 371 TR. This system is used because it utilizes a cheap energy source that dissipates heat from gas and has no ecological hazards, such as ozone layer depletion and global warming. The exhaust gas temperature is 500oC. Moreover, cooling loads for cold storage, which are used with thermodynamic models, and consistent fluid properties, performance, and size of cold storage were also investigated. The results obtained show that higher cold storage output comes from internal factors as compared to external factors. In addition, the absorption refrigerant with Tevaporation is 5oC, capacity 403 TR and Qabsorption is 984 kW, Qgenerator is 1066 kW, Qevaporation is 1411 kW, Qcondenser is 1493 kW, with an absorption coefficient of performance (COP) of 1.32 and power consumption of 158,25 kW. Furthermore, after calculations, analysis, and field experiments, it shows that the internal factor of the cooling load is higher than the external factor sourced from bananas in the cold storage. This phenomenon occurs probably due to the product being refrigerated, following the soar cooling capacity. Thus, the waste energy in PLTGU 3x1 MW has tried to be utilized by the refrigerant absorption system.

Abstract

Extended Reality (XR) is the technology that allows blending virtual and physical worlds using augmented reality (AR) and Virtual Reality (VR) to create a fully immersive experience. While WebXR is a web based XR environment built on a JavaScript framework that enables interactivity of AR and VR devices within the web browser. Contemporarily, educators are demanded to explore the variety of new media in practicing interactive learning, specifically in an academic environment. Arguably, VR has recently been identified as one of the most popular gamification mediums. It can create an environment that is both physically and digitally engaging. This paper reviews, simplifies as well as recommends a better component management system in the VR production pipeline using practice-based research methodology.
