Abstract

The technology of Wireless Sensor Network (WSN) can be used in a wide variety of needs for example in terms of its network of offices, companies, health care, and even daily activities that require the WSN. However, in terms of the functions that are owned by WSN technology required monitoring against resources consumed in order not going waste of resources. Meanwhile, on the other hand monitoring the transfer of certain activities require the existence of a state. For the problem of the excessive use of power resources in the intermediate implementation mechanism needed quite a long low power on sensor nodes in some conditions one of which was the sleep mode on a periodic basis. Taking and sending of data sensors this time using gas sensor MQ-7. Mikrokontroller used in the sensor node is system has low power features ATmega328p in its components. For the method used in protocol the MQTT-SN is mechanism of publish-subscribe communication serves as a regulator of event-driven architecture on each state. Protocol on the MQTT-SN has four state two of which also feature sleep available which are suitable for the application of energy-saving systems. After testing done on these results are obtained when the ATmega328p normal average current of 45.15 mA and when the sleep of 26.47 mA with the reduction of current of 18.68 mA.

Abstract

Management information is the main thing that has to be met by companies with a large and complex data. Currently, many hospitals, clinics, health centers, as well as the practices of doctors have used information system to facilitate data management and improve the quality of service to patients.But Klinik Elisa Malang encountered obstacles in registration of patients and medical record search.One patient could take 5-15 minutes to perform the registration process, including the search of the patient's medical record or creating medical record documents for new patients.This process can take much longer if a patient's medical record document was not found or is found in the broken state, the officer should make a new medical record. Based on these problems, the authors developed the electronic medical record system and online patient registration web-based that provides medical registration for old patients and also has features that are related to the patient's medical record management that have been converted to electronic form.The author uses the software development life cycle with waterfall model. Testing is done using unit testing with whitebox method and validation testing using blackbox method that produces valid values on all test cases, and compatibility test with 82% valid results.

Abstract

Twitter is a social media that is still widely used today. Like other social media Twitter is useful for making friends, exxchanging messages, and information about various things such as entertainment, economy, politics, and so forth. Twitter is also useful for finding information about the state of traffic on a road by accessing traffic accounts on Twitter. However, tweets are often found with ambigous words about the condition of the road. So tweets needs to classified to make it easy for road users. Classification begins with doing preprocessing stages on training and test documents, then proceeding with weighting TF-IDF until the classification stage using the NW-KNN (Neighbor Weighted K-Nearest Neighbor) method. Based on the implementation and testing carried out on the study of Malang City Traffic Congestion Classification Through Media Twitter Using Neighbor Weighted K-Nearest Neighbor (NW-KNN) method which uses 600 training data and 150 test data, obtained results of 0.7336507 for the average precision, 0.2210526 for recall, 0.3002686 for f-measure, and accuracy obtained at 0.665.

Abstract

Low Rate Wireless Personal Area Network (LR-WPAN) is a communication protocol standardized by the group of IEEE 802.15.4, the focus of its development is to create an architecture that uses low power, has wide range and reliable data transmission. One of its product is Zigbee. Zigbee focus on reliable data transmission could be disrupted if congestion happen due to the density of increased traffic data in its network. Congestion can be prevented by applying the right queue management in its buffer. One of the queue management is weighed random early detection (WRED), the advantage of using WRED is that the mechanism of the queue management not only focus on preventing the congestion but also able to accommodate the type of package that needs to be prioritized in its services. Implementation of WRED in Zigbee was carried out to measure architectural performance for avoiding congestion, which in this study implementation is simulated using Riverbed Modeler simulator. Architecture performance in terms of avoiding congestion was analyzed using parameters of throughput, queue delay, global delay and packet drop. The testing scenario was carried out by comparing WRED to the random early detection (RED) queue management, whereas both queues uses the min thresh and max thresh mechanism to handle congestion. Results of the test concluded that with smaller package size and smaller threshold the use of WRED will be more optimal shown by throughput parameter which is 1.5% better than RED, whereas with larger packet sizes and larger max thresholds the use of RED will be more optimal shown by the throughput parameter values 0.6% better than WRED.

Abstract

Culverts are a water channel that is very beneficial for the environment in the community. With the culvert the public must be responsible to maintain well in order to avoid things that are not desirable like flooding due to clogged or overflowed. Clogged water channels because the people who often dispose of waste into culverts or other water channels so that plastic waste or organic waste clog water channels due to too much waste. Therefore, a blockage monitoring system was built on three aqueducts with each node using an ultrasonic PING sensor to measure the water level and the water flow G1 / 2 sensor to measure the rate of water velocity on the culvert. Data taken from the sensor will be processed by Arduino Nano microcontroller by using fuzzy method. Because the location of the culvert with a monitoring post is relatively far then the data processing will be sent using wireless NRF24L01, then LED RGB (Light Emitting Diode Red, Green, Blue) as output will produce conditions on the culvert with a red flame is stated danger, green declared alert and blue otherwise safe. in this study fuzzy method has been successfully applied on a system with 100% accuracy with average processing time of delivery is 1236, 1045 and 1133 millisecond.

Abstract

Before the advent of RTOS, embedded systems using primitive interrupt to initiate a process of multitasking. Hiking the cultivation of Oyster Mushrooms or other mushrooms, we require preparatory steps include setting up the exact location or suitable for placing House mushrooms, prepare the mushroom seeds, prepare a sterile growing media and other means of treatment. To implement an RTOS in fungi and plant watering monitor automatically using the FreeRTOS. FreeRTOS is applied using three Task in all nodes the actuator sensor & first serve which monitor temperature and humidity, the second monitor large discharge of water and the water flow, turn on the water pump automatically, and the last function sends data to the gateway node. After all the Task was implemented, node gateway will receive data from the sensors and actuators & node sends the data to the webserver. Data is sent in the form of readings of temperature, humidity, large discharge of water, lots of water flow, and the State of the water pumps are turned on or not. When data is received to the webserver, data is entered into a database and displayed via a web page named "Control Jamur". From the results of testing, FreeRTOS has time of 141,35ms execution longer than without the use of FreeRTOS amounted to 126,2ms. However, the accuracy of the readings of the sensors is increasing and more keep FreeRTOS desired deadline. If it exceeds the deadline then the system will be deemed useless and result in system failure. FreeRTOS may keep the deadline that made the system so useful and can avoid system failure.
