    Internet of Things Data Security Model Using Elliptic Curve Diffie Hellman and Advanced Encryption Standard

    Authors: Sopian Alviana, Muhamad Faishal Azizi, Dedeng Hirawan

    Abstract

    The internet of things (IoT) is a transformative technology that enables hardware devices to connect and communicate through computer networks. Among the commonly used protocols in IoT is the message queue telemetry transport (MQTT). While MQTT offers the advantage of lightweight data transmission, it falls short in ensuring data security and confidentiality. This limitation can be addressed through the implementation of cryptographic algorithms. This study aimed to enhance the security of data on IoT devices by utilizing a combined cryptographic approach that integrates elliptic curve Diffie Hellman (ECDH) with the advanced encryption standard (AES). The research methodology involves several key stages: analysing and determining system requirements, designing a security model, and conducting performance testing. Success is evaluated based on parameters such as memory and processor usage. Experimental results demonstrated that the integration of ECDH and AES effectively secures data on IoT devices, with memory usage recorded at 8.69% and processor utilization at 21.3%. © School of Engineering, Taylor’s University.

    Junior High School Students in Solving Mathematical Ill-Structured Problems: Analyzing Using Harel Theory

    Authors: Shelly Morin, Didi Suryadi, Sufyani Prabawanto, Dedi Sulistiyo

    Abstract

    This study explored how students think when solving ill-structured mathematics problems. This research method was a qualitative case study involving class VIII junior high school students. Data collection techniques were done by giving ill-structured mathematics problems in the form of geometry material, observation, and in-depth interviews. Furthermore, after students solved the problem; to further describe the student’s answers, in-depth interviews were conducted to explore and dig up further information. The results showed that some issues were found: the complexity of the problems given to students became a challenge in solving unstructured geometry problems, students had difficulties interpreting the problem due to limited prior knowledge, especially regarding geometry material, and the problems given required creativity in finding solutions. Students’ constraints were in the lack of prior knowledge, especially geometry materials, and creativity to find and establish strategies to build solutions according to their knowledge. This research contributed to uncovering students’ thought processes when constructing solutions based on their prior knowledge to identify learning difficulties in more depth. This research also showed that the diversity of students’ ways of thinking provides different problem-solving opportunities. © School of Engineering, Taylor’s University.

  • Enhancing Students’ Advanced Mathematical Thinking in Algebra through Three Worlds Journeys on Mathematics Worksheets

    Enhancing Students’ Advanced Mathematical Thinking in Algebra through Three Worlds Journeys on Mathematics Worksheets

    Authors: Nadya Dewinda Agustin, Mohamad Syarif Sumantri, Arita Marini, Sri Pernia Warakmulty

    Abstract

    This study investigates the development of primary students’ advanced mathematical thinking (AMT) skills in solving algebra problems using worksheets based on Tall’s three-worlds journey of mathematics. Employing an explanatory sequential design, this research integrated quantitative and qualitative data from 40 fifth-grade students. Instruments and data analyses were validated through expert judgment and triangulation. The findings reveal that students achieved AMT skills, including mathematical representation, creativity, abstraction, and proof. Approximately 40% of students reached the natural phase, 35% progressed to the natural-to-formal phase, and 35% attained the formal-axiomatic phase. These results occurred because Tall’s approach leverages children’s natural tendencies to play, imagine, and explore, fostering deeper reasoning. This study impacts mathematics education by demonstrating that AMT skills can be nurtured at the primary level through structured scaffolding, enhancing students’ cognitive development and problem-solving abilities in algebra. © School of Engineering, Taylor’s University.

    UNIKOM STUDENT EXECUTIVE BOARD IMPLEMENTS AI-BASED WASTE SHREDDING AND SMART MAGGOT TECHNOLOGY: REALIZING SUSTAINABLE INNOVATION IN MEKARMANIK VILLAGE 

    BANDUNG, UNIKOM – The Student Executive Board (BEM) of the Universitas Komputer Indonesia (UNIKOM) has demonstrated the real contribution of students in solving environmental issues through the “Impactful PKM” program. The PKM activity was carried out over one semester from September 2025 to January 2026, presenting innovations in waste shredding technology and an Artificial Intelligence (AI)-based Smart Maggot cultivation system as solutions to increase independence and sustainability in waste management in Mekarmanik Village, Cimenyan District, Bandung Regency.

    Residents of Mekarmanik have long faced challenges in managing household waste, particularly organic waste that accumulates due to limited shredding equipment and slow decomposition processes. In response to this situation, BEM UNIKOM launched a collaborative program between BEM Nandanasena, the Codelabs Division, and the Labkat Division of UNIKOM, focusing on promoting the application of smart technology that can be directly utilized by the community.

    The Impactful PKM Program in Mekarmanik Village was carried out by involving 22 students, including 16 students from BEM Nandasena, 4 students from Codelabs, and 2 students from Labkat, as well as a committee from the UNIKOM study programs of Informatics Engineering, Information Systems, Communication Science, Management, Accounting, and Computerized Accounting, under the direction of the Chief Executive, Andrias Darmayadi, S.IP., M.Si., Ph.D., with Moch Nafis Azhar as the person in charge of the activity, and guided and accompanied by UNIKOM lecturers, including Dr. Hj. Supriyati, S.E., M.Si., Ak., CA., ASEAN CPA., C.PI., CIAP, AMKI., and Dian Dharmayanti, S.T., M.Kom. Cross-disciplinary collaboration was implemented to ensure each stage of the activity was carried out effectively and on target.

    The series of program activities began with the handover of an automatic waste shredder and an AI-based maggot cultivation system to the Mekarmanik Village Government. This innovation received a positive response from residents because it not only speeds up the process of managing organic waste but also produces outputs that can be reused, such as maggot feed and organic fertilizer.

    In her speech, Dr. Supriyati emphasized the importance of utilizing appropriate technology to create an independent and empowered environment. “We hope that this tool will not only be a solution for waste management, but also trigger a change in people’s mindset about the importance of recycling and environmental independence,” she said.

    Meanwhile, support also came from the village government. The Head of Mekarmanik Village, Mr. Nanang, expressed his appreciation for UNIKOM contribution. He considered that the presence of waste shredding technology was the answer to the problem of organic waste management that had been burdening residents. Expressions of gratitude were also conveyed by the Heads of RW 04 and RW 05 as well as the Secretary of Karang Taruna RW 04, who had directly experienced the benefits of this tool.

    After the handover of the equipment, the activity continued with training on the use of waste shredding equipment, the theory and practice of maggot cultivation, and the application of the “AI-based Smart Maggot” system. The training used a hands-on method so that residents could understand the maggot cultivation cycle and become skilled in developing the processing system independently. An educational game session was also held to ensure residents’ ability to apply the knowledge they had been given.

    Appreciation for the program was evident from the enthusiasm of the residents and the village government. The Secretary of Mekarmanik Village hopes that the PKM activities can continue until the evaluation stage in the third year, as a commitment to maintaining the sustainability of technology-based waste management.

    The Impactful PKM program also strengthens the implementation of UNIKOM Tri Dharma Perguruan Tinggi (Three Pillars of Higher Education), particularly in the aspect of community service. The application of waste shredding technology and AI-based Smart Maggots in Mekarmanik Village is expected to become a model of independent, productive, and sustainable village-level environmental innovation.

    Through the Impactful PKM Program, UNIKOM affirms that collaboration between academics and the community can produce real solutions that not only address environmental issues but also open new economic opportunities for the community. The program marks the first step toward smarter and more competitive environmental management. (Directorate of Hms & Pro)
