    Paper Title: Mindful Teaching, Diverse Learning: Harnessing Multiple Intelligences for Students Success

    In recent times, a noticeable trend has emerged—many undergraduate students are raising concerns about the teaching techniques employed by their lecturers. This highlights the fact that students exhibit varied learning preferences based on their distinct types of intelligence. To address this, the multiple intelligence approach offers a solution to assess students' individual profiles and their favoured teaching styles. Employing multiple intelligence tests becomes a means to categorize student types effectively. Leveraging the Multiple Intelligence (MI) approach, educators can tailor teaching methodologies to align with students' needs. This study employs a qualitative research design, investigating how 70 lecturers perceive the multiple intelligences theory in education. Carefully selected participants from diverse disciplines and experience levels are chosen through purposeful sampling. Thematic analysis of interview data aims to uncover themes and patterns related to lecturers' comprehension, beliefs, attitudes towards multiple intelligences, their integration into teaching practices, and the challenges encountered. Ultimately, the findings promise to offer valuable insights to educators and institutions, facilitating the seamless integration of diverse teaching strategies.

    Paper Title: Portuguese Military Cyber Human Resources Management

    The Portuguese public sector institutions, including the Armed Forces, are facing increasing cost reductions due to budget cuts resulting from economic crises and the pandemic scenario. Although Lean thinking aims to reduce waste and improve customer satisfaction through continuous improvement, its implementation often faces challenges. The Portuguese Air Force was a pioneer in applying Lean methodology, achieving positive results in crucial areas, and extending this methodology to other Armed Forces institutions could contribute to better use of national resources. This paper explores the implementation of Lean philosophy in the Portuguese Armed Forces, specifically in the recruitment, integration, and retention of talent in Cyber Security. Centralizing and simplifying processes and resources, as well as resolving challenges inherent to the area, maybe the right approach to respond to the implications on National Security and Defense, providing necessary resources for the capture, training, and maintenance of essential Cyber teams and processes. The mentality based on work processes needs to change to speed up the use of resources and the behaviour of executing elements.

    Paper Title: Bacteriogenic synthesize of gold nanoparticles and their separation using inexpensive zirconia-ceramic composite membrane

    The present study addresses the application of membrane technology to recover the bacteriogenic synthesized gold nanoparticles from their aqueous solution. An inexpensive zirconia ceramic composite membrane was developed for this purpose and employed for the ultrafiltration of gold nanoparticles. For this, firstly, the low-cost ceramic membrane support was prepared using inexpensive clay-based raw materials such as china clay, quartz, and kaolin, after that the support was coated using zirconia particles spray pyrolysis method. After coating, the composite membrane was characterized and found that the permeability, porosity, and pore size of the membrane were 1.08 × 10 -7 L/m 2 hPa, 30% and 100 nm, respectively. However, the pore volume, specific surface area, and average pore size of the prepared zirconia particles were measured using Brunauer, Emmett, and Teller (BET) surface area analyzer and found to be 0.083 cm 3 /g, 22.04 m 2 /g, and 10.9 nm, respectively. Furthermore, using this coated membrane and a dead-end filtration setup, the gold nanoparticles were separated from their aqueous solution. The gold nanoparticles ultrafiltration study was performed at distinct transmembrane pressures (69–345 kPa) and AuNPs concentrations (25-100 mg/L). The optimum permeate flux and gold NPs rejection, at 207 kPa transmembrane pressure and 100 mg/L feed concentration, were found to be around 12.8 L/m 2 h and 60%, respectively. Our findings suggest that using clay-based ceramic support, a low-cost zirconia ceramic composite membrane may be developed for the separation of metallic nanoparticles from their aqueous solutions.

    Paper Title: Nonformal Educators’ Resilience Amidst Digital Era Challenges

    The educational landscape has seen substantial changes in the quickly evolving digital era. Nonformal educators, pivotal in community learning and empowerment, frequently encounter distinct problems that have not been thoroughly examined. This study aimed to comprehend the resilience, dedication, and commitment exhibited by nonformal educators in Indonesia in the face of these difficulties. Using a case study methodology, a deliberate selection was made of 15 nonformal educators who were then interviewed to gain insight into their experiences and perspectives. The transcribed interviews were analyzed using theme analysis, resulting in the identification of patterns pertaining to resilience and commitment. The findings indicate that despite encountering financial limitations, lack of acknowledgement, minimal safeguards, and insufficient facilities, these instructors persist resolutely in their pursuit. While the wider educational industry focuses on accrediting and standardizing, nonformal educators face fundamental challenges, sometimes with inadequate assistance. However, their resolute will and commitment to enhancing community empowerment are particularly notable. This study highlights the necessity of providing more focus and assistance to nonformal educators, emphasizing their crucial role in grassroots educational initiatives.

    Paper Title: Intelligent Alerting System Development by Network Media Semantic Analysis and Face Recognition

    Nowadays, the network has become the major data provider to everyone. Various providers feed data to the end users to achieve the flow of information for their own purposes. In this research, we develop an intelligent alerting system that can automatically sematic analyze the contents from the network and extract the altered information including event description and suspect’s photo. We crawl the PTT, Dcard, and Google News in Taiwan as our sources to process due to the popularity of the three social network systems. These are the three very popular social media in Taiwan and real-time events, news is always posted to the three media very soon, therefore, we adopt them as our research source. Video monitors installed on campus or in the community after receiving alerts and photos will enter alert mode. Real-time face recognition will be issued for the people captured by the camera. Once the system recognizes the suspect, it will notify the security guard to take necessary actions to protect the people. There are two major parts to this research, the first one is the media semantic analysis and the second one is the real-time face recognition. It is an intelligent altering system that is capable to find out the suspected assault or rapist rapidly once he is captured by a monitor and recognized after people post the crime events to the media.

    Paper Title: Energy-efficient uniform parallel machines scheduling problem with deterioration effect

    Uniform parallel machines “UPM” scheduling problems have been extensively studied because of their broad industrial applications. However, these systems are subject to deterioration. Therefore, preventive maintenance activities are integrated into the system, making unavailability periods. Meanwhile, deterioration and maintenance activities increase the energy consumption in the workshop. And with the growing environmental and global warming concerns, energy consumption has become a priority for manufacturers. Thus, we treat an unspecified uniform parallel machine scheduling problem with deterioration effect and maintenance activities to minimize the total consumed energy. First, we formulated an original mathematical programming model. This MILP model gives solutions for small instances in an affordable computational time. However, we proposed some lemmas throughout a mathematical analysis, and develop an LBH-SA algorithm to efficiently solve larger instances of the problem. To confirm the algorithm's performances, we test it for different instances, and compare its results with optimal solutions given by the model.

    Paper Title: Improved Risk Matrix for Distribution Transformer in East Java: Analytic Network Process and Modified Total Ownership Cost

    Many studies have been conducted on risk assessment in distribution transformers. However, previous studies have not fully considered the risk analysis and cost impact of damage to distribution transformers. In addition, the use of the Modified Total Ownership Cost Method is one comprehensive approach to calculating the cost implications of damage to distribution transformers. The use of risk matrix to determine likelihood factors and consequence factors still does not consider several factors, and the factors used often have equal weight and are interrelated. This study collects all the indicators used for probability and consequence factors in the risk matrix and applies the Analysis Network Process to give weight to those factors. The result is a more accurate risk evaluation model, supporting decision-making regarding investment in distribution transformers in East Java. A modified and weighted risk matrix was applied to 65 distribution transformers, of which 3 had low risk, 14 had moderate risk, 38 had high risk, 8 had very high risk, and 2 had extreme risk.

    Paper Title: NS1 DENV Antigen Detection by Nanobody Ligands Using the Biotin Sensor: Working Principle

    Dengue virus infection (DENV) is still one of the most common diseases in the world and commonly leads to death. Accurate early diagnosis is necessary to provide the right treatment. Non-structural protein NS1 (NS1) of dengue virus can be considered as a promising biomarker of viral infection. In general, monoclonal antibody is used as the biosensor which can detect and bind to NS1 as the antigen. Because of its better stability, higher solubility, and good ability to be genetically manipulated, nanobody is being widely developed to overcome the drawbacks of monoclonal antibody. Kinetic evaluation is important in designing a biosensor and can be done using Surface Plasmon Resonance (SPR). The small size (~15 kDa) of nanobody makes it difficult to be immobilized using EDC-NHS coupling methods. As an alternative, a biotin sensor with avidin sandwich binds biotinylated small molecules used in this study. The strong and specific binding between avidin and biotin ensures that the small molecules labeled with biotin are firmly immobilized on the sensor surface, leading to accurate and sensitive detection. Biotin- based sensors can also be regenerated by dissociation under appropriate conditions. Therefore, this study focuses on the working principle of biotin sensor which is used for evaluating the interaction between nanobody and NS1 antigen.

Later analysis also revealed that human errors occur due to the following reasons: Lack of knowledge of the overall system and fundamental operations, Insufficient confirmation of operations and Incomplete knowledge of the sequence of operations. the role of the instructor will be explained to reduce the causes of human error and to improve educational performance according to the implementation and development of each scenario based on expert justification and reference to IMO and SOLAS Standards. various safety procedure scenarios for all Engineers in the hope of minimizing accidents that cause loss of life at sea. For the purpose of training engine plant operations using a PC-based Engine Room Simulator (ERS), describe the features of human errors by incompetent trainees in marine engine plant operations and demonstrate the necessary improvements in training to reduce such errors from an educational technology point of view. Examination of these data has shown that errors occur primarily due to errors of omission and inadvertent action. Further analysis was carried out on these errors by the engineer trainees to determine the characteristics of errors caused in the process of acquiring procedural knowledge for operations according to the implemented development of various safety scenarios.

    Paper Title: SOCIAL NETWORK PRACTICES OF RURAL FOOD PROCESSING PRODUCT BY MSME DOERS WITHIN THE PROJECTION OF DIGITAL IN KEDIRI REGENCY INDONESIA

    The underlying idea of the research was the awareness of rural MSME doers to apply digital technology. Currently, the digital technology implementation has been increasing by 19 million MSMEs since 2022. Then, the targeted projection is – 30 million MSME doers in 2024 with the tagline "MSMEs go digital." This matter could change communication, media, public space, and cultural power. This study comprehended and analyzed the MSME doers in Kediri regency that experienced the practical implementation changes of digitalization, starting from the expanding network process, system change, provision of separate spaces, and the efficiency of MSME doers by getting into the related communities and applying digital technology optimally in Kediri regency. This qualitative research applied an interpretative approach to reveal the truth, life reality, and multiple aspects to study various points of view. The researchers took the theory of Manuel Castells' Network Society to explain the social network process of digitalization of MSME and its implementations. The researchers also observed the practices in Kediri regency. The results showed the networks of the MSME doers in rural food processing products based on digital transformation could establish social identity, experience development, power domination creation, and information capitalism
