<![CDATA[In this study, an information system was created to remind users of the length of sitting time to avoid the risk of health problems due to sitting too long. The device is designed and made in two parts, sitting cushion and application on the smartphone. In the seat cushion the limit switch sensor is placed to detect the sitting position and temperature sensor to detect the temperature of the bearing as an indicator of the long sitting. The data detected by the sensor will be sent to the microcontroller and prepared to be sent to the smart phone. The data to be displayed using an android application with Bluetooth communication. Display on the smartphone in human body posture accordance to user's sitting position. There are three body positions, namely the normal position, tilt to the left and tilt to the right. If the body position is tilted, then the smartphone will give an alarm warning to restore the sitting position to the normal position. The bearing temperature detection results will be displayed in the form of numbers with a green background as the indicator of the temperature is still normal, yellow if the bearing temperature rises and red if the temperature has exceeded the permitted normal limit. This means the user has been sitting too long and must stand or rest for a while. To remind the user to stand up, the smartphone will also give a warning by turning on the alarm.]]>

<![CDATA[This research designs and makes low-cost portable devices to monitor risk patients losing their balance such as vertigo patients and cause dizziness, fall or not. This tool can determine the patient condition and send information in SMS notification and telephone calls to the patient's family. This tool uses ATmega 328 (Arduino Uno) and tilt sensor HMC5883L (accelerometer) GY-273 as the patient's body tilt detector and GSM SIM800L module for sending SMS notifications and phone calls for remote information while for short range notifications used LEDs and Buzzers. The position detection of vertigo patients works by reading the slope of the patient's body with a tilt sensor (accelerometer) and if the patient's position is no longer robust or unbalanced, then this condition trigger the GSM SIM800L module activate phone calls. When the patient falls and presses the push button, this condition ask the GSM SIM800L module sending SMS notifications. The results of testing performed on the device in detecting falls as much as 30 times, obtained the value of the sensitivity of dizziness activity by 87% and the value of sensitivity on activity fell by 90%. The system requires an average of 8 seconds after the activity falls to send SMS notifications to users of telephone numbers, and also requires an average of 5 to 6 seconds after dizziness to make phone calls to users of telephone numbers. It is expected that the making of this tool can ease monitoring in vertigo patients while on the move]]>

<![CDATA[Modernization is indeed very influential in the lives of people today, with the existence of this modern era, everything is always related to technology. The place is far enough and to find out the condition of the excess current makes the PLN officials also have difficulty because there is no monitoring tool from the situation. From the description above, the author found the idea to make a Simulation System for Monitoring Overcurrent Systems in the PLN Phase One Phase Using a Microcontroller-Based Web. The tool uses the Arduino Mega microcontroller coupled with ACS712 Flow sensors, and Ethernet Shield Modules. The way this tool works is to detect the electric current that enters the Input from the electrical equipment load on the ACS712 sensor. In testing the author only uses 3 pieces of light as a burden to determine the state of excess current. If you use 1 load, the current that is read is 0.44A with a 100 Watt lamp power. And if the load is added by 1 load with 75 Watt of light power, the current that is read becomes 0.77A. Then the load is added with 1 lamp with a power of 60 Watt, then the current becomes 1.05A with the result at all three drop loads.]]>

<![CDATA[Banyaknya tambak ikan air tawar yang terdapat di daerah limau Manis Kecamatan Pauh Kota Padang ini disebabkan adanya bendungan air yang dibuat pemerintah untuk pengairan sawah sehingga dimanfaatkan oleh masyarakat untuk berkolam ikan air tawar baik didepan rumah maupun diladang yang tidak produktif, karena sumber air berlimpah sehingga kebutuhan akan air bagi petani tambak ikan di limau manis kecamatan Pauh Kota Padang tidaklah menjadi masalah. Namun permasalahan akan terjadi bila hujan turun dimana air pada bendungan akan meningkat sehingga ini akan meningkatkan jumlah debet air yang masuk pada kolam ikan, ini menjadi permasalahan bagi petani tambak karena ikan akan mudah mati, ikan akan keluar dan juga ikan akan berpenyakit disebabkan banyaknya debet air dalam kolam di karenakan air keruh. Berdasarkan permasalahan tersebut saya mencoba membuat sebuah alat menggunakan mikrokontroler yang dapat diatur menggunakan keypad dan mengontrol level air menggunakan sensor ultrasonik serta tingkat kekeruhan air pada kolam air deras ditampilkan pada LCD secara otomatis dengan cara mengatur buka tutup pintu keluar air kolam sehingga tinggi level air kolam dapat diatur sesuai kebutuhan. Cara mengatur posisi motor DC dapat dimanfaatkan dengan menggunaakan mikrokontroler agar petani tambak ikan air deras dapat memantau kondisi air pada kolam dan juga dapat mengatur ketinggian air yang akan masuk keluar kolam secara otomatis, guna meningkatkan hasil panen ikan serta mencegah kematian ikan akibat kondisi air yang tidak baik]]>
