Comparison of Conventional CNN Sequential API and Functional API for Microalgae Identification

Microalgae is widely known for its application in producing biodiesel and other health supplements. However, microalgae are also the leading cause of harmful algae blooms that may affect consumers and sea wildlife. The current microalgae identification method requires professionals, resources, budgets, technologies, and time. Therefore, a novel approach to identifying microalgae has been produced by implementing deep learning, specifically the Convolutional Neural Network (CNN). Due to the blooming of research in the deep learning field for microalgae identification, this research aims to compare application programming interface (API) use and study its effects on the accuracy and loss of a model. Using a light microscope, the microalgae images' datasets are self-collected from the AlBio laboratory at the Malaysia-Japan International Institute of Technology, Universiti Teknologi Malaysia. The microalgae species were Acutodesmus obliquus, Monoraphidium sp, Spirullina sp, Tetradesmus deserticola, and Desmodesmus perforatus. The architecture used to identify the microalgae in this research was the conventional CNN with different APIs, functional and sequential. The functional API resulted in 0.85 accuracies and a loss score of 3.77. On the other hand, the sequential scored 0.89 and a loss of 0.32. This study concluded that the sequential API was better than the functional API for a linear convolutional neural network. However, further improvement to the model could be applied by applying better hyperparameters and parameters to prevent underfitting and improve the model’s accuracy.

Preface: The 5th International Conference on Environmental Resources Management (ICERM) 2023

Water resources have become crucial for livelihood in the previous decade [1,2]. Population pressure, climate change, hydrological disasters, and inadequate implementation of integrated water resource management have all been topics of concern among water resource professionals [3,4,5]. Meanwhile, poor hydrological data and a lack of government policy focus (especially in developing countries) on hydrological data collecting are challenges that make it difficult to implement water resource management and integration to secure human livelihood [6,7].The Faculty of Geography, Universitas Gadjah Mada, particularly the Department of Environmental Geography, has a long track record and experience in addressing water resource concerns and their relationship to other elements of livelihood. In this case, in an era of rapid development, particularly in developing countries, and increasing awareness of global climate change, the Department is looking to highlight the most recent issues and discuss efforts related to sustainable water resource management by hosting the 5th International Conference on Environmental Resources Management (ICERM).The conference, with the theme “Water resources management for sustainable livelihood,” was held on September 26, 2023, in Jogjakarta, Indonesia. 57 presenters from 5 nations attended the conference, which was preceded by 12 keynote and invited speakers from 6 countries. The 5th ICERM’s sub-topics are as follows:• Implementation of integrated water resources management;• Livelihood and water resources management in urban areas;• Water equity for sustainable development;• Marine sciences and coastal management;• Ecosystem and tropical lake management;• New urban agenda and sustainable urban development;• Natural resources and disaster management;• Environmental sciences and climate change; and• Human geography and spatial planningFinally, we would like to extend our appreciation and gratitude to all parties that assisted and cooperated towards making this conference a success. This conference is supported by Faculty of Geography UGM and the Publishing Agency of UGM, and in cooperation with Flinders University, Universiti Teknologi Malaysia, Seoul National University, Kobe University, National Taiwan Normal University, CSIRO, SEALNet-Malaysia University of Science, Indonesian Geographer Society, Indonesian Hydrological Society, Indonesian Limnological Society, Indonesian Groundwater Experts Association, and Chinese Academy of Science.

FV-MViT: Mobile Vision Transformer for Finger Vein Recognition.

In addressing challenges related to high parameter counts and limited training samples for finger vein recognition, we present the FV-MViT model. It serves as a lightweight deep learning solution, emphasizing high accuracy, portable design, and low latency. The FV-MViT introduces two key components. The Mul-MV2 Block utilizes a dual-path inverted residual connection structure for multi-scale convolutions, extracting additional local features. Simultaneously, the Enhanced MobileViT Block eliminates the large-scale convolution block at the beginning of the original MobileViT Block. It converts the Transformer's self-attention into separable self-attention with linear complexity, optimizing the back end of the original MobileViT Block with depth-wise separable convolutions. This aims to extract global features and effectively reduce parameter counts and feature extraction times. Additionally, we introduce a soft target center cross-entropy loss function to enhance generalization and increase accuracy. Experimental results indicate that the FV-MViT achieves a recognition accuracy of 99.53% and 100.00% on the Shandong University (SDU) and Universiti Teknologi Malaysia (USM) datasets, with equal error rates of 0.47% and 0.02%, respectively. The model has a parameter count of 5.26 million and exhibits a latency of 10.00 milliseconds from the sample input to the recognition output. Comparison with state-of-the-art (SOTA) methods reveals competitive performance for FV-MViT.

Unravelling International Students' Preferences in Embracing Malaysian Cuisine: A Pilot Study

This pilot study aims to investigate the preferences of international students in embracing Malaysian cuisine during their tenure at local university. Students frequently experience difficulties in their social and academic environments. No study has been explored on the relationship between students’ views and perceptions of Malaysian food. The objective of this study is to precede further studies on key factors that influence international students' preferences for Malaysian cuisine that may perhaps provide insights for universities and local food establishments to promote more of Malaysian cuisine internationally. The pilot study was conducted at Universiti Teknologi Malaysia, Kuala Lumpur branch, which consist of a significant number of undergraduate and postgraduate international students. Kuala Lumpur has many options for type of restaurants and varieties of local cuisine. The research instrument used in this study is a self-administered questionnaire, that was validated and distributed to only international students. The study employed a quantitative method approach to understand the factors influencing the food choices of international students, towards Malaysian cuisine. The questionnaire developed includes demographic information, followed by the Theory of Planned Behaviour (TPB) sections, (i) attitude, (ii) subjective norms and (iii) perceived behavioural control. The findings of this pilot do prove that attitudes, social norm and perceived behavioural control had a significant positive effect on intention to consume Malaysian food with attitudes playing the main factor. The quality, taste and cultural background of the food product are the drivers that led them to consume local cuisine. This study has provided valuable insights for further research and the development of strategies to cater to the culinary preferences of international students in UTM Kuala Lumpur especially. The findings thus far could provide insights for local food establishments to enhance the promotion of Malaysian cuisine to international students, to potentially increase the demand for local foods and boost the industry's revenue.

Trends of Academic Publications: A Case Study of Malaysian Research Universities

The Ministry of Higher Education Malaysia granted five universities with Research University (RU) status, which are Universiti Malaya (UM), Universiti Putra Malaysia (UPM), Universiti Kebangsaan Malaysia (UKM), Universiti Sains Malaysia (USM), and Universiti Teknologi Malaysia (UTM). These RUs are expected to focus on research and innovation and become a model of Malaysian universities for research activities aimed at knowledge advancement. Publications are one of the performance indicators for RUs. Thus, this paper confined its scope to the publications produced from 2016 to 2020 by the five RUs. The study aimed to analyse the patterns related to the number of publications, subject areas, type of publications, international joint publications, and the language of the publications. The findings show that the number of publications increased for UPM, UKM, and USM over five years, while UTM champions four subjects: Engineering, Materials Science, Computer Science, and Environmental Science. Journal articles are the most prominent scholarly output for all RUs. All RUs actively collaborate with international scholars and use English as the primary language for publications.

Convolutional Neural Network Model for Sex Determination Using Femur Bones

Forensic anthropology is the critical discipline that applies physical anthropology in forensic education. One valuable application is the identification of the biological profile. However, in the aftermath of significant disasters, the identification of human skeletons becomes challenging due to their incompleteness and difficulty determining sex. Researchers have explored alternative indicators to address this issue, including using the femur bone as a reliable sex identifier. The development of artificial intelligence has created a new field called deep learning that has excelled in various applications, including sex determination using the femur bone. In this study, we employ the Convolutional Neural Network (CNN) method to identify the sex of human skeleton shards. A CNN model was trained on 91 CT-scan results of femur bones collected from Universiti Teknologi Malaysia, comprising 50 female and 41 male patients. The data pre-processing involves cropping, and the dataset is divided into training and validation subsets with varying percentages (60:4, 70:30, and 80:20). The constructed CNN architecture exhibits exceptional accuracy, achieving 100% accuracy in both training and validation data. Moreover, the precision, recall, and F1 score attained a perfect score of 1, validating the model's precise predictions. The results of this research demonstrate excellent accuracy, confirming the reliability of the developed model for sex determination. These findings demonstrate that using deep learning for sex determination is a novel and promising approach. The high accuracy of the CNN model provides a valuable tool for sex determination in challenging scenarios. This could have important implications for forensic investigations and help identify victims of disasters and other crimes.

The Influence of Entrepreneurship Education on University Students' Entrepreneurship Self-Efficacy and Entrepreneurial Intention

Entrepreneurship education in Higher Learning Institutions (HLIs) is vital to strengthening a country’s entrepreneurship ecosystem, which fosters economic growth, innovation, and job creation. Through entrepreneurship education, more job creators are expected to be created and nurtured with entrepreneurial awareness, knowledge, abilities, and support. Therefore, this study investigated the relationship between entrepreneurship education, namely entrepreneurship curriculum, entrepreneurship lecturers’ competency, and university entrepreneurship support in influencing entrepreneurship intention among Universiti Teknologi Malaysia’s students, with entrepreneurship self-efficacy as the mediator. The methodological approach of this study is a quantitative method. The population of this study was Universiti Teknologi Malaysia (UTM) undergraduate students with a sample size of 212 respondents, obtained using simple random probability sampling. Data collected from respondents was analysed using the SPSS statistical analytical tool by applying descriptive, regression and mediation tests. The study’s findings revealed that entrepreneurship curriculum and university entrepreneurship support have significantly influenced both entrepreneurship self-efficacy and intention. However, entrepreneurship lecturers’ competency was found to have an insignificant relationship with entrepreneurship self-efficacy and intention. The influence of entrepreneurship self-efficacy towards entrepreneurship intention was also significant. Meanwhile, the mediating effect of entrepreneurship self-efficacy between entrepreneurship education components (curriculum, lecturers’ competency, and university entrepreneurship support) and entrepreneurship intention were all significant. Thus, this study has provided insights for various stakeholders, predominantly academicians, HLIs, and policymakers, to understand the current scenario on the effectiveness of Malaysia’s entrepreneurship education.

Integrated Mass and Energy Balance Course Project using Spreadsheet for a Chemical Engineering Degree Program

In this innovation, team projects from two courses offered in different semesters are integrated. On top of that, students are trained to use a spreadsheet-based tool to solve the problem in the project. Those two courses are Mass Balance (SETK 1123) and Energy Balance (SETK 2133) offered to Chemical Engineering students in Universiti Teknologi Malaysia at their second and third semester. The main objective of the innovation is to scaffold the students’ understanding of the problems given to them in the projects. At the end of the project, they should be able to clearly see the overall processes in a typical chemical industry, starting from raw materials to the targeted products, by-products, and wastes produced. In addition to that, the projects also foster digital skills by enhancing the students’ skills to use the spreadsheet tools to solve Chemical Engineering problems. This is inline with their study as the students learnt about computer programming and spreadsheet tools in their first semester. From the students’ reflections, it can be concluded that this innovation are able to increase the comprehension of the students on the two courses, increase the skills in using spreadsheet tools for solving problems and also inculcate critical thinking and problem solving skills.

Salinity-Various Flow Characteristics Investigation in an Identical Meandering Channel

Estuaries are one of the most productive ecosystems in the world, providing significant resources for humans and animals. However, the influence of various rainfall patterns due to climate change has affected the estuarine system, leading to changes such as salinity intrusion. This study aims to verify how river discharge changes affect salinity mixing within a meandering channel and the effect of flow patterns due to curvature. An experimental hydraulic investigation was conducted at Universiti Teknologi Malaysia (UTM) Johor Bahru. The cross-sectional profiles along the meandering channel are discussed in this paper. The findings prevailed as a typical characteristic of the salt-wedge estuary and indicated the process of estuarine mixing. As the saltwater flow upstream, the salinity level drops due to the dilution process. Additionally, the greater density of seawater compared to freshwater causes it to remain in the lower layers of the water column. The flow pattern in curvature is influenced by the velocity of the inner and outer banks, where velocity has been seen to be higher at the outer bank, allowing the salinity to flow quickly near the inner bank. The present study will be useful in predicting the estuarine salinity response to river inflow.

What My Friends Are Up To? The Relationship between Social Media Usage and Fear of Missing Out among Undergraduates

The social media platform is extremely popular among undergraduate students. Along with the increase in social media usage, phenomena such as the fear of missing out are also becoming more prevalent among this group. It is hypothesized that excessive usage of social media contributes to the psychological decline of undergraduate students. This study aimed to examine the relationship between social media usage and the fear of missing out among undergraduate students. In addition, this study also examined the level of social media usage and the fear of missing out. The study adopted a quantitative approach, specifically a correlational research design. Data were collected from 306 undergraduates at Universiti Teknologi Malaysia using the social networking time use scale and fear of missing out (FOMO) scale instruments to measure social media usage and fear of missing out, respectively. Descriptive analysis revealed that undergraduates have a moderate level of social media usage and a moderate level of fear of missing out. Meanwhile, the inferential analysis revealed a significant positive relationship between the usage of social media and the level of fear of missing out among undergraduates. In conclusion, the study results indicate that social media usage does influence the fear of missing out among undergraduates, although the coefficient was weak.

Experimental Study on Depth-Averaged Velocity and Bed Profile in a Braided Channel with a Mid-Bar

Braided alluvial rivers with a mid-bar are common features occurred in alluvial river that consists of bifurcation and confluence channels. The formation of the mid-bar will affect the hydraulics of river systems in terms of velocity and bed morphology. The studies corresponding to the typical braided river with a mid-bar are still ongoing. This paper is to present the finding of depth-averaged velocity, Ud and bed profile at the bifurcation and confluence channel. A channel with a mid-bar and erodible bed was used in this research. The experimental work was carried out in the Hydraulic Laboratory at Universiti Teknologi Malaysia, (UTM). In the experiment, two types of flow which are low flow and high flow rates were considered. The study found that depth-averaged velocity distributions are influenced by flow discharge and varied at the braided channel. The highest Ud velocity is 0.35 m/s occurred at the bifurcation area and the lowest Ud is 0.2 m/s that was occurred at the confluence area. This genesis to more erosion occurred at the bifurcation area compared to the confluence area.
