Checking a patient's heart health is often done by recording the heart's electrical signals in the form of an Electrocardiogram (ECG). To identifya heart condition, it is customary to look at several extreme maximum and minimum points on the ECG signal known as PQRST points. Theheight of the extreme points and the distance (interval) between the points can be used to detect symptoms of heart disease such as arrhythmias.This study uses a Matlab-based maximum and minimum extreme point detection algorithm to detect PQRST points and analyze the position ofthese points to detect arrhythmia symptoms. Based on the test results using data obtained from Physionet MIT-BIH and cardiac patients at SaifulAnwar Hospital Malang, detection of the PQRST point can be done quickly and accurately using this method. However, this method is onlyintended to assist medical personnel in reading ECG signal recordings, not to replace the role of medical personnel in carrying out the diagnosis
ABSTRAKProses datangnya kebakaran selalu tanpa dapat diperkirakan dan diprediksi terlebih dahulu. Kapan datangnya, apa penyebabnya, tingkat cakupannya serta seberapa besar dampak yang ditimbulkannya, adalah hal-hal yang tidak bisa diperkirakan oleh kemampuan manusia. Perancangan sistem pengamanan kebakaran yang bertujuan untuk meningkatkan keamanan dan kenyamanan penghuni di gedung.analisa yang dilakukan adalah dengan mengukur dan mendata suhu serta melakukan serangkaian beberapa percobaan. Suhu dilengkapi dengan satuan celcius (C) dan asap menggunakan satuan PPM (part per million). Dengan cara kerja, sensor asap dan suhu akan mendeteksi secara sendiri dan bekerja dengan baik. Dan Hal ini untuk menghindari adanya kesalahan yang diakibatkan kenaikan suhu akibat sinar matahari ataupun asap akibat rokok. Jika Sensor suhu LM35 mencapai 40 C maka suhu akan mendeteksi dan buzzer akan berbunyi led akan menyalah Dan LCD 2x16 akan menampilkan "AWAS ADA ASAP". Jika Asap mencapai dari 600 ke atas sensor asap akan mendeteksi dan buzzer akan berbunyi, lampu led akan menyala lalu di LCD 2x16 akan menampilkan "AWAS ADA KEBAKARAN".Kata kunci: Detektor Asap, Lm35, Radio Frekuensi, Mikrokontroller Atmega328.
Abstrak: Tanaman merupakan tumbuhan yang dibudidayakan agar dapat diambil manfaatnya. Tanaman sebagai salah satu makhluk hidup yang sangat berguna untuk pemenuhan kebutuhan manusia. Perkembangan teknologi khususnya komputer sudah demikian majunya merambah setiap bidang kehidupan. Hampir semua aktifitas kegiatan manusia menggunakan teknologi moderen, mulai dari dunia industri, rumah tangga bahkan bidang pertanian. Mikrokontroler sebagai salah satu perkembangan teknologi sebagai kontrol sistem otomatis. Yang diharapkan dapat mempermudah setiap kegiatan yang ingin dilakukan. Perancangan Prototype penyiram tanaman otomatis menggunakan beberapa komponen utama sebagai input, control dan output. Untuk input menggunakan sensor kelembaban Soil Moisture YL-69, sensor suhu LM35, ultrasonik HC-SR04. Kontrol utama menggunakan mikrokontroler atmega 328. Dan output utama menggunakan water pump dan tampilan LCD 16x2. Selain itu ada juga beberapa komponen pendukung seperti resistor sebagai penghambat untuk reset pada kontrol mikrokontroler atmega 328, potensiometer sebagai pengatur blackligth pada LCD 16x2. Relay sebagai pemicu water pump yang diproses dari Kontrol mikrokontroler.
Internet Of Things (IoT) Is A Concept Where Internet Connectivity Can Exchange Information With Each Other With Things Around It. Many Predict That the Internet of Things (IoT) is “The Next Big Thing” in the World of Information Technology. System Testing Is Done In The Graha Indah District Of Lamongan Regency. Sensor Nodes Will Be Placed Near High Teget Sutet Network, Atmega 828 Microcontroller in this study as NodeMCU to be able to read data from sensors and convert the data obtained into the form of numbers that are easy to understand. Another function of the program is to send the data to the middleware every 50 seconds. Data retrieval every 60 minutes is intended to be able to get strong and weak GSM network signals that are close to the SUTET electricity network.
Shoes are one of the most important clothes for daily life. However, not just a season factor that affects of the problem to drying shoes when wet, could be due to the situation and conditions like in the evening that would not be possible and will not be able to find the scorching light or sunlight. Based on the problem, the author devising a shoes dryer as well as odor-causing bacterial disinfectant in shoes. The result of Prototype Box Dryer and Automatic Bacterial Disinfectant Odor Causing of Shoes in Microcontroller Based, when the power supply is given voltage then the tool will be working. How Prototype Box Dryer and Automatic Bacterial Disinfectant Odor Causing of Shoes in Microcontroller Based works : the first fan will lit up appropriate to humidity above 90%, the second fan will lit up appropriate to the temperature above 34ºC, heating element lit up appropriate to humidity above 90%, UV-C lamp will lit up appropriate to humidity below 89%. The result of the temperature and humidity will be showing on the LCD 16x2
