Novel Corona Virus (nCoV) infects human’s respiratory system. It spreads easily when an infected person makes a close contact with other people. To prevent its massive spread, it is necessary to ensure anyone coming to a certain place is not being infected. The symptoms include high body temperature (≥37.5°C) and low oxygen saturation level (≤95%). This day, most places only check the human body temperature. Thus, the authors are interested to make an attempt to design a system that is able to measure both human body temperature and oxygen saturation level. This work also applies the 7-DoF Upper-Body of Humanoid Robot to prevent virus spread from and to the employee. The system will detect the coming of visitors by using face detection. It requires 7.24 seconds to detect the visitor without a mask, and 1.26 second when the visitor wears a mask. The body temperature measurement was done using GY-906 temperature sensor with an error of 0.51%. For the oxygen saturation level measurement, MAX30100 pulse oximeter module was applied and showed an error of 0.78%. In addition, the upper-body of humanoid robot will perform some gestures to instruct the visitors in every process of the system. The implemented 7-DoF upper-body of humanoid robot has 93.33% gesture comprehension rate. In conclusion, the overall system has been tested and showed success rate up to 75%.

The research on reliability index of a feeder aims to evaluate the reliability level of a feeder using the Reliability Index Assessment (RIA) method. This method evaluates the reliability of a 20 kV distribution network by calculating the reliability indexes of each load point. The evaluation results show the reliability index value per section of the Kumpai Feeder at PT. PLN (Persero) ULP Siantan within one year. The SAIFI values are 0.0092; 0.0012; 12,477; 0.0596; 0.0204; 0.0470; 0.0155; 0.0728, the SAIDI values are 0.0277; 0.0042; 37,746; 0.1862; 0.0741; 0.1524; 0.0493; 0.2209, the CAIDI values are 3.0108; 3.5; 3,025; 3.1241; 3.6323; 3.2425; 3.1806; 3.0343, the MAIFI values are 0; 5,480; 0.2145; 0.0020; 0.0038; 0.0042; 0.0006; 0.0014. The calculation results show that the 20 kV distribution system at PT. PLN (Persero) ULP Siantan at the Kumpai Feeder can be categorized as unreliable. Because the SAIFI value of this feeder exceeds the standard set by PT. PLN (Persero) which are 12.477 times/customer/year and 3.2 times/customer/year, respectively. The factors affecting the reliability index of the Kumpai feeder are the number and duration of blackouts, the number of customers, and the length of the distribution system channel.

This paper aims to implement the prototype model to monitor and control the pH levels and nutrition plant (electrical conductivity-EC) supplied by a standalone photovoltaic (PV) module-connected battery (Lithium-Ion) on the greenhouse hydroponic systems. The pH and EC sensors are connected to the Arduino Uno circuit as a relay control to drive four pumps, i.e. the water flow pump, EC pump, pH up pump, and pH down pump. The greenhouse function to control pests and the impact of environmental non-uniformity caused by variation of wind speed, temperature, or sunlight so that hydroponic plants can grow in an appropriate environment. The Arduino Uno circuit with a 20 × 4 liquid crystal display (LCD) order four relays to monitor and control the four pumps of the greenhouse hydroponic system based on the coding which has been programmed previously. The prototype model is able to monitor and control the pH of hydroponic plant water at the level between 6-7 using a pH-up and pH-down sensor. This model is also able to monitor and control nutrition plant water over 1 mS/cm using an EC sensor. Finally, the proposed prototype is able to monitor and control EC and pH level to regulate plant growth in the greenhouse hydroponic system normally and in real-time.

In the field of transportation, telematics is used to obtain vehicle information using Global Positioning System (GPS) technology which is integrated with sensors so that vehicle information can be monitored. One of them is fuel monitoring. The fuel sensor has good accuracy in stationary conditions, but the tability of the data is disturbed when the vehicle is running on an uneven road and causes the tank to shake. This study discusses a fuel sensor noise reduction system using a Kalman filter to overcome the problem of data instability due to shocks. This research aims to reduce noise so that the filter results are closer to the actual result. Filtering is done by changing the process error covariance (Q) and measurement error (R) in the Kalman filter. The fuel sensor noise is simulated using a simulator tank driven by an actuator that can tilt towards the x-axis and the y-axis to resemble the behavior of a vehicle. The fuel level data from the sensor readings are sent by GPS via the cellular network to a server which is then filtered using a web application. From the test results obtained the best filter with (Q) equals 0.1^3 and (R) equals 0.1^3. The average error of the best filter results is 4.73% where this value is 1.92% smaller than the average error of sensor data before filtering, which is 6.65%. Therefore, this proves that the system can reduce noise that occurs in the fuel sensor with the Kalman filter.

Currently, cut chrysanthemum cultivation in a greenhouse is still using a conventional system. Temperature and soil moisture are the most important factors in the growth process. If the temperature and humidity of the soil are not conditioned, the roots will quickly rot and slow the growth process of chrysanthemums. Internet of Things is an integrated system with a data-based server that stores data in the cloud from sensors so that the system can be monitored remotely in real-time. Based on this, an integrated system was designed to make it easier for farmers to condition the temperature and humidity of the chrysanthemum flower soil. In temperature conditioning, if the temperature of cut chrysanthemum is detected <24 ℃ then the heater will be "on" by adjusting the fan rotation and vice versa. Meanwhile, soil moisture conditioning is carried out by distributing water if the detected soil moisture is <50%, then the water pump is in the "on" state. The data on the degree of temperature and the percent of soil moisture will be recorded into the cloud which will then be displayed in the form of graphs and history data on the webserver and Android. By using this system, it is found that the growth process of cut chrysanthemums can grow 7 days faster than the standard harvest time of 30 days.

Everyone must have a rush outside the house, sometimes in a hurry even forget to turn off and turn on the light in the house during the morning or night. At times like this, of course, that makes people lazy to go back to the house to turn off the light that causes electricity waste and make time efficient to turn on the light. In this study a prototype of lighting control will be made where observations have been made about the prototype need. Then look for literature related to light control prototypes. The prototype method uses the blynk application as a light controller connected to the internet with the media via wifi. ESP-01 as a microcontroller processes commands from a smart phone which then results in controlling both the off and on the lights as well as the receiver and transmitter in the lighting control system. Thyristor switch module as an electrical switch instead of a manual switch at home to turn on or turn off the light through commands from the microcontroller. This prototype is very easy to use because through a prototype smart phone can be controlled, so this is a solution for humans to turn on or turn off the light by utilizing wifi in the house. From the experiments that have been carried out the average speed of the prototype tool receives an order from open source blynk application in 0.28 seconds

This research discusses the Arduino Uno based public street lighting intensity control system. The street lighting technology applied so far is still conventional technology that is classified as wasteful of energy because it still uses a continuous lighting system or an On-Off system. PJU problems arise because of too much power consumption caused by the use of large power lamps and lamp operating times. This research utilizes Arduino Uno and RTC to control the value of the variable voltage output transformer based on time division. This system has been able to control the voltage of 400 watt sodium lamps. The output voltage of the transformer has been divided into three levels, namely level 1, level 2 and level 3. The division of this level is based on the operating time of the lights, namely level 1 at 1830 WIB to 2200 WIB, level 2 at 2201 WIB until 2359 WIB, level 3 at 0000 WIB until 0530 WIB. Transformer output voltage at level 1 can be 220 volts. The output voltage of the transformer at level 2 can be 210 volts. Transformer output voltage at level 3 can be 200 volts. The intensity of the 400 watt sodium lamp light at level 1 is an average of 99.9 lux. The intensity of the 400 watt sodium lamp light at level 2 is an average of 85.45 lux. The intensity of the 400 watt sodium lamp light at level 3 is an average of 78.6 lux.

The division of this level is based on the operating time of the lights, namely level 1 at 1830 WIB to 2200 WIB, level 2 at 2201 WIB until 2359 WIB, level 3 at 0000 WIB until 0530 WIB. Transformer output voltage at level 1 can be 220 volts. The output voltage of the transformer at level 2 can be 210 volts. Transformer output voltage at level 3 can be 200 volts. The intensity of the 400 watt sodium lamp light at level 1 is an average of 99.9 lux. The intensity of the 400 watt sodium lamp light at level 2 is an average of 85.45 lux. The intensity of the 400 watt sodium lamp light at level 3 is an average of 78.6 lux.","PeriodicalId":32754,"journal":{"name":"Elkha Jurnal Teknik Elektro","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87110674","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}

The use of multiprocessor methods in robotics systems has a significant impact on overall robot performance. The Master-slave method is a model of a multiprocessor system where there are several processors that communicate with each other to carry out the robot's overall function. RS-485 can be used as a communication model in the master-slave method. RS-485 is a development of RS-232 which has the ability to communicate with several nodes. In this research, an experiment will be conducted to implement RS-485 to support the master-slave processor communication. Stages of research began with making system design, which includes the design of embedded hardware systems, the design of data communication protocols on RS-485 networks, software design, followed by implementation and testing. The test is carried out to measure the time response of the device to three data transmission models, namely broadcast, addressing slaves without responding and addressing slaves with responses. The test results carried out on three slaves with a communication speed of 9600 bps. Measured response time on broadcast data transmission is 8ms, and address slave without response is 7ms. Whereas delivery by addressing slaves with responses, shows that the measurement method cannot be applied.
