Bank Indonesia (BI) as the central bank in Indonesia has launched a movement to use non-cash instruments in conducting transactions on economic activities. The majority of Indonesian people are increasingly ready to trade without cash or cashless society. The country's economic policy factors, the availability of various non-cash payments, and online sales and purchases, encourage the tendency to use non-cash transactions (e-payment). One way to find out these trends is to use a model. Models can help understand and explain real phenomena more easily and efficiently than directly observing. One model that can be used is Agent Based Modeling and Simulation (ABMS). By using ABMS, the development of models with complex behaviors, dependencies, and interactions can be developed more easily. ABMS is able to describe processes, phenomena, and situations. In this study, the factors that influence the tendency to use e-payment are obtained from various references. From these factors, then created a scenario as a sub-purpose of this model. In simulations using ABMS, detailed descriptions explained based on ODD Protocol elements can be more easily understood and complete. ODD systematically evaluates a model. The advantage is that ODD can improve the accuracy of model formulas and make the theoretical basis more visible.

Small and Medium Enterprises (SMEs) have a very important role in the development of the Indonesian economy. Special Region of Yogyakarta (DIY) is one of the provinces that has many SMEs. The SMEs has the potential to penetrate the international market, one of which is a wooden handicraft SMEs. Woodencraft can be used as a cluster because it fulfills three factors that enable it to compete in the international market, namely the factor of global market needs, the factor of superior products, and potential SME product factors. However, woodencraft SMEs still face obstacles in product penetration abroad, namely obstacles from internal SMEs, the government, and international markets. The solution offered to help woodencraft SMEs to go international a program called Integrated Woodencraft Cluster, which is a cluster of woodencraft SMEs that integrates supply chain management (SCM) based distribution systems with four main lines (suppliers, production, sales, and information), internet-based information systems, and Just In Time (JIT) principle. The program involves local government, civil service, wood handicraft SMEs, suppliers of raw materials, and academics. The advantages of Integrated Woodencraft Clusters compared to conventional clusters include having a clear vision for exporting production, a structured managerial system, having an export agency, supplying raw materials, clear lines of information, and being able to facilitate all SME woodencraft, both on a small scale and intermediate.

Perbedaan suku bangsa merupakan salah satu faktor yang berpengaruh terhadap variasi antropometri. Walaupun Indonesia terdiri dari berbagai suku bangsa, penelitian antropometri yang membahas hal tersebut masih sangat terbatas. Penelitian ini dilakukan untuk mengumpulkan data antropometri mahasiswa Indonesia, sekaligus membandingkan dimensi antropometri antara mahasiswa Indonesia bersuku Batak dan Jawa. Pengukuran 58 dimensi antropometri dilakukan pada 286 mahasiswa laki-laki dan 210 mahasiswa perempuan. Hasil pengukuran disajikan dalam statistik deskriptif dalam rerata, simpang baku, dan nilai persentil. Selain itu, perbandingan antropometri antar jenis kelamin dan suku dilakukan dengan uji t dan uji Mann-Whitney. Hasil perbandingan pada peserta perempuan dan laki-laki untuk masing-masing suku menunjukkan perbedaan yang signifikan hampir di seluruh dimensi, di mana peserta laki-laki cenderung memiliki dimensi yang lebih besar daripada perempuan (p<0,05). Perbandingan antropometri antar suku pada peserta laki-laki menunjukkan bahwa terdapat perbedaan signifikan pada 13 dimensi dengan kecenderungan laki-laki bersuku Jawa memiliki dimensi kaki yang lebih besar, sedangkan peserta laki-laki bersuku Batak memiliki dimensi lebar seperti lebar mulut dan lebar kaki yang lebih besar. Pada peserta perempuan, terdapat perbedaan yang signifikan pada 27 dimensi di mana terdapat kecenderungan peserta bersuku Batak memiliki dimensi posisi duduk menghadap belakang yang lebih besar, sedangkan peserta bersuku Jawa cenderung memiliki dimensi tangan yang lebih besar

Stroke is one of the leading causes of death globally, after heart disease and cancer. It often results in brain damage that impairs the function of certain body parts, including the ability to communicate. Communication disorders in stroke patients can severely impact mental health and quality of life, with studies showing that 53% of affected individuals experience depression. This study aims to design and develop an assistive communication tool tailored to the needs of stroke patients. The Quality Function Deployment (QFD) method was employed to ensure that user requirements are thoroughly addressed in the design process. Data were collected through observations and interviews with nurses and families of stroke patients. The House of Quality (HoQ) analysis revealed three main priorities for development: an integrated information system, blink-based control, and a feature to detect patient needs. The resulting solution is IISAAC (IoT-based Integrated System with Augmentative and Alternative Communication), a communication system that uses eye blink signals detected via an EOG sensor. These signals are converted into specific messages and sent directly to the nurse’s WhatsApp application. IISAAC enables more effective communication between patients, caregivers, and medical staff, helping to address the communication barriers commonly experienced by stroke survivors.
