Abstract

This paper aims to design a semi-circular patch microstrip antenna that can work at a frequency of 2.4 GHz (band 2360 MHz - 2400 MHz) to support Wireless Body Area Network technology (WBAN). One of the devices connected to WBAN technology is a Holter monitor and medical data recorder that forms a medical network for post-operative or monitoring ICU patients (Intensive Care Unit). To support one of the WBAN technologies, an antenna is needed that has considerable gain and bandwidth characteristics. To increase the gain and bandwidth, the array method is used on antennas with inset feed unification. The antenna design was simulated using CST Studio Suite 2019. The use of array methods on microstrip antennas can increase the gain by 132.9%, which is 5.73 dB. The simulation results obtained a return loss of -17.223 dB with a bandwidth of 88.3 MHz in the frequency range of 2357.6 MHz - 2445.9 MHz

Abstract

Pokok masalah penelitian ini adalah bagaimana upaya atau cara agar bisa mengatasi motivasi dan hasil belajar matematika peserta didik kelas VII5 SMP Negeri 17 Makassar yang sangat rendah, yang dalam hal ini peneliti akan melakukan sebuah eksperimen dengan menerapkan Pendekatan Realistic Mathematic Education(RME). Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK), yang menggunakan model Kemmis dan Tanggart yang terdiri dari 2 siklus. Metode pengumpulan data yang digunakan adalah observasi, tes hasil belajar, angket, dan dokumentasi. Analisisdata yang digunakan adalah analisis deskriptif kuantitatif, yaitu memberikan gambaran tentang hasil penelitian dengan cara mendeskripsikan motivasi dan hasil belajar matematika peserta didik berdasarkan data yang telah diperoleh selama penelitian. Hasil penelitian ini menunjukan bahwa terjadi peningkatan motivasi dan hasil belajar matematik setelah diterapkannya pendekatan Realistic Mathematics Education (RME) dengan peningkatan yang sangat signifikan yaitu dari skor rata-rata motivasi belajar peserta didik yaitu 67,74 pada tahap pra siklus, meningkat menjadi 73,51 pada siklus I dan meningkat lagi menjadi 78,80 pada siklus II. Sedangkan untuk hasil belajar peserta didik yaitu 39,40 pada tahap pra siklus meningkat menjadi 47,23 pada siklus I dan meningkat lagi menjadi 75,66 pada siklus II. Pada tahap siklus II kegiatan belajar mengajar lebih terarah dalam arti tidak kaku jika dibandingkan pada siklus I, ini disebabkan pada siklus I peserta didik maupun pendidik belum terbiasa dengan pendekatan yang diterapkan, tetapi motivasi dan hasil belajar peserta didik disiklus I sudah ada peningkatan jika dibandingkan dengan motivasi dan nilai hasil belajar peserta didik pada tes awal meskipun peningkatan yang terjadi kurang signifikan.

Abstract

Augmented Reality (AR) is an innovative technology that is able to present three-dimensional virtual objects in the real world, thus providing an interactive learning experience. AR-based learning media has the potential to help students understand abstract concepts in geometry transformation more clearly and interestingly. This community service aims to facilitate the learning process of students on geometry transformation material using Augmented Reality (AR) based learning media. The activity was carried out at Insan Cendekia Syech Yusuf High School with three main stages, namely the preparation, implementation, and evaluation stages. In the preparation stage, AR learning media development and preparation of learning tools were carried out. The implementation stage includes the introduction of the concept of geometric transformation and direct practice of using AR learning media by students. The evaluation stage was carried out with learning outcome tests and questionnaires to measure the effectiveness and learners' responses to the activities. The evaluation results showed that the average learning outcomes of learners were 74, with a good category. In addition, the average learner response to the implementation of mentoring is 72.36, which is included in the positive category. These findings indicate that AR-based learning assistance can make a positive contribution to learners. Thus, learning assistance using AR-based learning media is feasible to be applied in learning mathematics.
