<![CDATA[Shopping Mall merupakan area pusat perbelanjaan yang besar dan memiliki sistem keamanan seperti sistem layanan informasi yang dapat dimanfaatkan oleh konsumen untuk mendapatkan informasi yang dibutuhkan. Penggunaan sistem layanan informasi pada area Shopping Mall bagi konsumen terkadang sangat tidak efektif. Hal ini dikarenakan konsumen membutuhkan waktu yang lama dalam mendapatkan informasi, dimana konsumen terlebih dahulu harus mencari lokasi tempat sistem layanan informasi tersebut. Hal ini menjadikan sistem keamanan pada Shopping Mall menjadi lemah. Indoor Positioning System (IPS) merupakan sistem yang dapat digunakan untuk mengetahui posisi pengguna melalui kekuatan sinyal Wi-Fi yang didapat dalam gedung. Pada penelitian ini, penulis membuat suatu aplikasi android yang dapat digunakan untuk mengetahui posisi konsumen pada area Shopping Mall tersebut.]]>

<![CDATA[Diabetes mellitus and gastric infections can be detected through bad breath bad breath (halitosis). Halitosis is a condition where the smell of bad breath occurs when a person exhales (usually smells when talking). This study aims to create an oral health identification and classification system (halitosis). TGS-2602 gas sensor will detect gas levels in the mouth of the patient, and send data in the form of an analog signal to the ATmega 328 microcontroller. By programming the data read on the Raspberry Pi, the data from the microcontroller is stored in a file and then the data is processed using the Fast Fourier Transform method. (FFT) so that the desired data pattern is obtained. The data pattern of the Fast Fourier Transform (FFT) output will be used as input data on the Learning Vector Quantization (LVQ) neural network method. System testing is done to people with halitosis and not halitosis bad breath. The results showed that the percentage success rate of sensor responses to mild halitosis samples was 25%, moderate halitosis samples were 50%, acute Halitosis samples were 50% and non-halitosis samples were 100%.]]>

<![CDATA[In this study, the total dissolved solid (TDS) in water was made using conductivity sensor which the sensor works by using the principle of conductance that is the ability of the solution in delivering the electric current, so the more content of solute contained in the water the greater also the value of its conductance. The measurement results of the sensor will be compared with the next setpoint value will be used to turn on the booster pump which will do the filtering process in order to decrease the TDS water content by using RO membrane. The performance of sensor readings when first used is boosted by the time at which the system takes 3 minutes to reach a stable state, while for the whole system is influenced by the volume of water that will decrease its TDS level. The test results are presented in the form of graph of change of TDS water content over time, the difference of time required to decrease the TDS level by 15 ppm for 1 liter of water for 6 minutes, 2 liter of water for 10 minutes and for 3 liters of water for 16 minutes.]]>

<![CDATA[Braking Automation system is needed to make people do their job in braking while driving. This paper aims to design and construct an electromagnetic braking automatic system that able to make car stopped before colliding a barrier by applying of the Proportional Integral Derivative (PID) method. To find out how the effective utilization of PID control on electromagnetic braking automatic will be compared with the results of braking without using PID. Determination tuning result of controller PID parameter obtained by using the trial and error methods and obtained the PID parameter values that suitable are Kp = 2.98, Ki = 0.104 and Kd = 1.35. The ultrasonic sensor used as detection the distance to a barrier. From the testing results of electromagnetic braking system with PID control more effective than with the electromagnetic braking system without PID because it can be seen from the side cessation of the car approaching set point, the results of the electromagnetic braking with PID control better than the electromagnetic braking without PID control.]]>

<![CDATA[The development of computer technology in Indonesia is currently growing rapidly. In line with this the development of the Potato Seed Center (BBI) of potatoes was also developing, as was the case at the Kerinci Regency mother's seed plant. Processing of potato hatchery and hatchery development reports has not been computerized because it still uses Microsoft Excel, causing some problems including making reports on the development of potato hatcheries and searching for data takes quite a long time. This led to a weak processing of hatchery data processing systems and the development of reports on the development of Kerinci Regency potato seeding. Seeing the above problems, a potato seeding information system at the Central Seed Agency (BBI) was made using a C # programming language that had used a database and used Crytal Report to assist in the development of a report on the development of potato seedlings in the potato seed plant in Kerinci district.]]>

<![CDATA[Rice is the staple food of the majority of Indonesians and most of the population work as farmers. However, the amount of rice produced are still insufficient. To meet the rice needs for the society, it should increase the amount of rice production by focusing on rice field quality such as the water level rice fields. In this study a prototype rice field irrigation system is designed using AWD irrigation method by regulating open activation and closing the inlet gate and exit gate based on the age of paddy which are calculated using RTC and the height of paddy water measured using ultrasonic sensors. The system also designed to receive input from the age of paddy and deactivate the system from the mobile application through the ESP8266 module. Test results from this system can measure water level with accuracy of 95.68% and read real-time time with 98.67% accuracy. The servo motor NFC DS04 works to open the door with a duration of 60 seconds and closes the door with a duration of 56 seconds. The paddy irrigation regulating system can regulate the water level with a success percentage of 81.48%. The system can receive input and deactivate the system with a percentage of success of 70%.]]>

<![CDATA[Body’s height and mass measurement usually are measured with a different instrument without a knowledge to know the ideal body mass index (BMI). Ideal BMI is related to our health condition especially for people who do exercise. Usually people just guess the BMI from a visual condition that sometime give a false measurement. This paper proposes a device that can measured ideal BMI based on Brocha method based on microcontroller. The body’s height will be measured using ultrasonic sensor while the body’s mass will be measured with a load cell. The results show that the proposed device can predict the BMI well. The height measurement has a successful rate of 80%.]]>
