Abstract

Classroom action research (CAR) has been carried out with the aim of knowing the level of student achievement after being given an experimental learning method. This is because the experimental learning technique is a way of teaching in which students conduct an experiment about something and observe the process. Write the results of the experiment then the results of the observations are submitted and evaluated by the teacher. The CAR model used is the problem-based learning flow and the Spiral and Taggart models. The results of the evaluation showed that student achievement had increased after the experimental method of learning was compared with conventional learning models.

Abstract

This study aims to observe the ability of a thin layer of zinc oxide (ZnO) which is applied to sensor technology. Currently, the low detection limit of the sensor is a problem in its use. Metamaterials offer resonant properties in increasing sensitivity, but their performance is still below the current high modern technology. The high engineering properties of metamaterials provide opportunities for realizing renewable metamaterials. ZnO thin layer semiconductor material as a transparent conductive oxide can provide a wide detection potential. The ability of ZnO thin films to be adapted to metamaterial sensors can be further investigated and improved for the future.

Abstract

Intravenous (IV) infusion therapy is a medical procedure that involves the insertion of fluids directly into the patient's vein using a needle/cannula. Mismanagement during infusion fluids replacement due to negligence and shortage of medical personnel and human error must be addressed promptly. Increasing in numbers of patients throughout the Covid-19 pandemic has raised the use of infusion and the error percentage in manual infusion monitoring has also escalated, as consequence, the needs of automatic-handy tools with affordable price become a concern. The infusion monitoring system used consists of three parts, namely sensing and computing, communication, and User. This device allows monitoring and visualization of IV therapy infusion for each patient in real-time, at a remote location.

Abstract

This study explores the potential of orange peel extract as a stabilizing agent in the synthesis of ferroelectric BaTiO3. Characterization using Fourier transform infrared (FTIR) spectroscopy revealed the presence of strong acidic functional groups (O-H stretching at 3300 cm-1 and C–H sp3 chain at 2800 – 2993 cm-1 and carbonyl groups of double C–O at 1650 cm-1 in orange peel extract. These findings indicate that orange peel contains organic compounds that can be utilized in various applications.

Abstract

Perovskite materials, including barium titanate (BaTiO3), are important ferroelectric materials in industry and research today. Ferroelectrics have unique properties such as piezoelectricity, high permittivity, and electrocaloric and electrooptic effects that are beneficial in technological applications. BaTiO3, for example, is a lead-free ferroelectric material relevant for FeRAM and ferroelectric tunnel junctions. However, research on BaTiO3 flexible thin films is still limited, especially in the context of flexible substrates. Therefore, research in the preparation of stable and flexible BTO ferroelectric films is crucial for the advancement of nonvolatile memory devices. The manufacturing method in this study is the Sol Gel Method where the relative molecular mass of BaCO3 material is calculated, then the mass value is entered with the composition of (X)BaTiO3-(1-X)BaZr0.5Ti0.503. After the test is performed using mangosteen leaves, the resulting wave peaks from the FTIR Spectroscopy analysis can be seen. This is one of the characterization methods used to analyze the molecular structure and functional groups of various materials from which samples are made. This analysis indicates that mangosteen leaves contain various organic compounds, including alcohols, alkanes, and carbonyl compounds. In this research, further development is needed so that improvements can be made in the synthesis of ferroelectric material BaTiO3 used as a stabilizing agent.

Abstract

Riau Province stands out as one of the most rapidly developing regions in Indonesia, showcasing significant advancements economy, population, and tourism. The strategic positioning of Riau Province along the world's busiest routes, establishes this province as a focal point for diverse activities from multiple nations. Furthermore, the natural resources of Riau Province provide it as a significant business hub by substantial activities. This undoubtedly impacts the cross section both business and tourist visitors from local and international. Unfortunately, it is found that information pertaining to Riau tourism is under-addressed the visitors’ need. Therefore, the chatbot artificial intelligent (AI) is developed to deliver comprehensive information about tourism in Riau, encompassing tourist attractions, culinary, and merchandise destinations. This chatbot is adopted a prototyping approach for software development with natural language processing, employing tools such as Xampp, Visual Studio Code, PHP for programming language, and the Botman for the library. This chatbot is then integrated with a customized website platform utilizing an accessible API. The questions are derived from commonly asked questions on the tourism platform, limited into five tourist attractions, culinary options, or merchandise’s spot. To evaluate, a black-box and user acceptance testing techniques will be employed to verify that the application operates as intended and receives favorable feedback from users. This chatbot grows into the smart and responsive tool tailored to tourism needs in Riau. This tool supports the Society 5.0 that concerns on human centric, technology, and resilience social and community while preserving the cultural elements of Riau’s Malay heritage.

Abstract

The development of antenna technology is increasingly developing in medical sensor applications. The medical sensor antenna can be strengthened with a split ring resonator (SRR) metamaterial structure. Metamaterial is an artificial material that has high resonance manufacturing properties and this can potentially be implemented into microstrip antenna structures. This research aims to design, simulate and analyze the characteristics of metamaterials regarding the frequency function and performance of an antenna combination of 1 – 4 metamaterials with a triangular SRR ring radius of 3.5 mm. The results of this research show that the metamaterial characteristics of permittivity, permeability and refractive index are negative. Furthermore, in the antenna application, the implementation of a 4 SRR triangular metamaterial combination structure has more optimal performance. The results show that antenna performance parameters produce return loss is -41.18 dB, the bandwidth is 3.86 GHz and gain is 3.82 dBi with an omnidirectional radiation pattern.
