Abstract

Abstrak. Oksigen memainkan peranan vital dalam tubuh untuk mengatur sistem peredaran darah. Namun jika kadar saturasi oksigen dalam darah (SpO2) berkurang atau tidak mencukupi maka dapat menyebabkan sesak nafas, bahkan dapat mempengaruhi fungsi kerja otak. Perangkat oksimeter digunakan untuk mengukur kadar saturasi oksigen dalam darah dengan pengukuran secara non-invasif, sehingga kekurangan oksigen dalam darah dapat dideteksi lebih awal. Oksimeter yang tersedia saat ini umumnya menampilkan hasil SpO2 tidak terhubung ke jaringan sehingga tidak dapat dipantau secara jarak jauh. Oleh karena itu diperlukan suatu perangkat yang dilengkapi dengan fitur monitoring dalam jaringan agar dapat memantau kondisi partisipan secara real-time. Penelitian ini bertujuan untuk mengembangkan sistem monitoring pengukuran saturasi oksigen dalam darah yang dapat diakses secara remote menggunakan smartphone. Alat rancangan ini menggunakan sensor MAX30100 dan NodeMCU ESP8266 sebagai mikrokontroler. Hasil pengukuran alat rancangan dapat dipantau secara real-time melalui website menggunakan aplikasi Blynk. Data pembanding yang digunakan adalah alat Oksimeter komersial. Pengujian telah dilakukan pada partisipan laki-laki berusia 14 dan 22 tahun, dan perempuan berusia 18 dan 45 tahun. Hasil pengujian secara keseluruhan menunjukkan bahwa alat yang dirancang relative sama dengan oksimeter komersial, yang ditunjukkan oleh nilai thitung ttabel. Abstract. Oxygen plays a vital role in regulating our blood circulation system. However, if the oxygen levels in the blood decrease or are insufficient, it can cause shortness of breath and even affect brain function. To address this problem, an oximeter provides an effective solution by providing a device that can measure blood oxygen saturation without having to place any device inside the body. Currently available oximeter devices usually only display the SpO2 results on the device itself. Therefore, a device with a remote monitoring feature is needed to monitor participants’ condition in real-time. This research aims to develop a remote-access blood oxygen saturation measurement monitoring system using the MAX30100 sensor and the NodeMCU ESP8266 as the microcontroller, the values can be viewed in real-time on website by the Blynk app. The comparison data used is a comercial oximeter device. The participants were the males aged 14 and 22 years, and the female aged 18 and 45 years. Herein, we found that the designed instrument shows excellent performance in which ttest ttable from overall data.

Abstract

Abstrak. Proses pembelajaran di Indonesia saat ini kurang mendorong siswa dalam mengembangkan keterampilan berpikir kritis. Metode yang diterapkan umumnya bertujuan untuk mampu menjawab soal-soal yang diujiankan sehingga sedikit sekali siswa yang berani mengemukakan gagasan dan ide-ide orisinil. ISLE-based STEM merupakan salah satu model pendekatan yang mendukung pembelajaran secara kontruktivisme. Model ini mendorong siswa untuk terlibat langsung dalam proses pembelajaran dengan melakukan berbagai aktivitas fisik, sehingga membantu mereka dalam merepresentasikan penalaran kualitatif dan mengembangkan kemampuan pemecahan masalah. Metode yang digunakan dalam penelitian ini adalah deskriptif analisis kerja dan aktivitas berdasarkan penelitian tindakan kelas yang dilakukan kepada siswa kelas VIII MTS dan kelas XI MAS Dayah Daruzzahidin. Peneliti menemukan bahwa awalnya siswa mengalami kesulitan dalam memahami fenomena fisika yakni gelombang. Hasil penilaian tindakan kelas menunjukkan siswa memperoleh skor yang rendah pada kemampuan ilmiah. Peneliti mengamati siswa sering mengeluh bahwa tugas-tugas yang diberikan sulit sehingga guru perlu memotivasi siswa dengan memberikan ide-ide yang dapat memancing kemampuan berpikir siswa. Seiring berjalannya waktu, para siswa mulai terbiasa dan menjadi lebih antusias dengan kegiatan tersebut. Melalui tahapan-tahapan tugas yang harus diselesaikan pada modul, siswa berhasil mengonstruk pengetahuan tentang gelombang dan karakteristiknya dan dapat menganalisis hubungan cepat rambat gelombang tali (v), tegangan tali (F) dan massa jenis tali (µ) berdasarkan eksperimen yang dilakukan. Abstract. The learning process in Indonesia currently does not encourage students to develop critical thinking skills. The method used generally aims to be able to answer the questions being tested so that very few students dare to express original ideas. ISLE-based STEM is an approach model that supports constructivist learning. This model encourages students to be directly involved in the learning process by carrying out various physical activities, thereby helping them to represent qualitative reasoning and develop problem-solving skills. The method used in this research is a descriptive analysis of work and activities based on classroom action research conducted on students of class VIII MTS and class XI MAS Dayah Daruzzahidin. We found that students had difficulty understanding the physics of waves at first. The results of the class action assessment showed that students obtained low scores on scientific abilities. We observe that students often complain that the assignments given are difficult, so teachers need to motivate students by providing ideas that can stimulate students' thinking skills. Over time, the students began to get used to and became more enthusiastic about these activities. Through the stages of the tasks that must be completed in the module, students are successful in constructing knowledge about waves and their characteristics and can analyze the relationship between the speed of wave propagation of the rope (v), the tension in the rope (F) and the density of the rope (µ) based on the experiments carried out.
