Kurangnya aliran darah ke otak dapat menyebabkan kelumpuhan, biasanya hanya pada satu sisi tubuh. Fisioterapi pada pasien pasca stroke ringan dilakukan dengan metode terapi gerakan antara lain yaitu elbow dan knee flexion. Fisioterapi adalah metode pengobatan yang umum digunakan oleh masyarakat, pengobatan ini mahal dan memerlukan mobilitas. Berdasarkan data riset kesehatan dasar, ditemukan bahwa status ekonomi merupakan salah satu penentu utama efektivitas fisioterapi. Oleh karena itu, dibuatlah alat smart hand glove terapi pasien pasca stroke yang digunakan pada bagian tangan dan dilengkapi sebuah aplikasi yang disebut sebagai \"Therapy Stroke Technology (TASTECH) untuk monitoring. Alat ini bekerja dengan integrasi antara sensor MPU6050 dan MAX30102 yang terhubung dengan ESP32 serta dapat dimonitoring oleh dokter atau terapis. Dari hasil pengujian akurasi sensor MPU6050 mampu mendeteksi sudut dari 100-900 sebesar 98,64%. Kemudian untuk sensor MAX30102 setelah diuji akurasi dengan perbandingan pulse oximeter tipe Lk87 didapatkan nilai akurasi SPO2 99,37% dan rata-rata BPM 99,22%.

The increasing use of photovoltaic which is starting to spread in various regions is one proof that renewable energy is starting to be relied on. This has both positive and negative impacts, both for the power system as a whole and for electrical equipment. This article discusses various previous studies that examined the effect of the use of photovoltaic on the deterioration of the distribution transformer condition. This review article is divided into three parts. The first is the effect of PV penetration which affects the performance of the transformer insulation based on the loading during operation.

Pada penelitian ini metode pengaturan kecepatan yang digunakan adalah metode Direct Torque Control (DTC) dimana DTC mampu mengatur fluks dan torsi secara langsung serta dapat dilakukan tanpa menggunakan sensor kecepatan. Adapun kontrol yang digunakan yaitu Jaringan Saraf Tiruan (JST) menggunakan Model Reference Control (MRC). Respon plant mampu beradaptasi terhadap nilai dari kecepatan referensi yang diberikan. Hasil pengujian menunjukkan bahwa kontrol JST mampu mengendalikan motor induksi dengan respon waktu yang cukup baik, hal ini dapat dilihat saat diberi kecepatan referensi sebesar 150 rad/s didapatkan nilai time constan sebesar 0,8693 s, rise time sebesar 1,2917 s, settling time sebesar 1,5536 s, time delay sebesar 0,622 s serta error steady state sebesar 0,9%. \u0000  \u0000ABSTRACT \u0000Speed regulation was one of the problems that occurred in induction motors. induction motors were the most commonly used motors in industry world, transportation business and others. The advantages of an induction motor were it had a simple and robust design, low cost, high effeciency, good power factor, and easier maintenance. In this study, the speed regulation method used was the Direct Torque Control (DTC) method where DTC was able to regulate flux and torque directly and it can be done without using a speed sensor. The control used was Artificial Neural Networks (ANN) using Model Reference Control (MRC). The plant response was able to adapt to the value of reference speed given. The test results showed that the ANN control was able to control the induction motor with a good response time. It can be seen when it was given a reference speed of 150 rad/s, the time constant value of 0.8693 s, rise time of 1.2917 s, settling time of 1.5536 s, delay time of 0.622 s and error steady state of 0.9%.","PeriodicalId":53405,"journal":{"name":"Jurnal Eltek","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42113194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
