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.

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.

Abstract

One of the technological development of wireless communication is Wireless. Currently developed into Wireless Sensor Network (WSN). A technology consisting of nodes as scattered within the scope of the system using a wireless network. One of the utilization of WSN technology is for application implementation to know temperature, weather, distance in the surrounding environment, then can exchange data through network node node that has been connected. One of them is if there is damage to fixed communication, WSN can be applied as secondary communication or other planning, as communication network infrastructure which is expected to be used when main telecommunication infrastructure have problem that is using Mobile ad hoc network (Manet) technology applied to Wireless Sensor Network (WSN). Manet in other ways can be interpreted as collected nodes, then move random (dynamic), then generate a temporary network by not relying on the existing structure. By utilizing Beagleboneblack as a Manet node, WSN can be applied as a communication between nodes. Beagleboneblack is a mini-computer open source-hardware product with linux Angstrom ARM support, plus many pin headers, digital pins, analogs, pwm and others will be very powerful. In addition to using the default OS, we can also use Linux Beaglebone board OS like Debian 8.6. Sensors are installed on each node, so the Manet can be built as a mobile network.

Abstract

In human life is heavily dependent on agriculture. To meet the needs of everyday human life then takes the process of planting, harvesting and land sports. For a short time as well as the limitations of power is a challenge that must be faced by the farmers. So did the problems facing tomato farmers who must sort out the tomato based on a different level of maturity - different. Tomato growers should be picking tomatoes first and then sort it based on the level of ripeness. This is done because each level of maturity tomatoes have different uses. Of the matter, the author makes a tomato based parser system level of maturity. Level of maturity is detected using the color tomato. To detect the color of the tomatoes then it needs three sensors on the left side, top, and right system. Tomato fruit is placed in the middle of the system on the box then motor stepper will push it so it just below the sensor. Then the color of tomatoes will be read by a third color sensor. After that the Bayes method will look for opportunities and will classify the tomatoes into three categories. After that the system will drain the tomatoes into the container according to the degree of ripeness by opening and closing the line using a servo motor. This research has as many as 45 data training data and each level has 15 kematangn data. The result of the test there is a 10 x 9 x 1 x and correct errors. From these tests can noted that 90% of system accuracy.

Abstract

WSN was implemented in densely populated area by using zigbee as the communication protocol. It was chosen to be the communication protocol because it is applicable in the extreme area. The selection of mesh topology due to each node is connected to each other, so they can communicate and switch the information among them. The selection protocol of routing Ad-hoc On-Deman Distance Vector (AODV) due to the route search on AODV is only needed when the route request is exist. In this research, testing was done in three scenarios, namely, test based on the condition where the barrier is exist and is not exist, test based on distance and the amount of the data. Based on the test, the analysis of several test parameters, such as throughput, delay and packet loss. Based on the result of testing and analyzing the Zigbee maximum distance in sending the data censor was 40 meter in a barrier condition, with the highest throughput value was 72 bps, the highest delay value was 0,0028 ms and the highest packet loss value was 70% at 50 meter distance. On the amount of data based testing, the highest throughput value was 65.3 bps, the highest delay value was 3.872ms, and the highest packet loss value was 47% from 30 data. Furthermore, the condition with and without barrier based test resulted some values, such as the highest throughput value was 65.3 bps, the highest delay value was 3.136ms and the highest packet loss value was 35%.

Abstract

Temperature and humidity monitoring based on WSN (Wireless Sensor Network). Monitoring system based on WSN has advantages compared to cable-based in addition to installation, maintenance and repair costs. The use of XBEE-S2 is better used for long-term monitoring than nRF because it only uses a 3.3 v low voltage. Even though it is expensive in terms of cost, if it is calculated for the long term it will be better if you have to replace it regularly. The simple implementation of the temperature and humidity monitoring system in the XBEE sensor network based building can be applied in chicken farms which helps to monitor the incubator temperature remotely and the use of Arduino as a Microcontroller is the right choice because of features that match the XBEE character that requires TX and RX pins and DHT-11 sensors that require a lot of pins. The choice of topology in sending data is also very important to know before installing the system to get maximum results. The node sensor uses Arduino uno and uses the XBEE-S2 module as a medium for sending and receiving data and uses two different Topologies, star topology and tree topology, which tests distance and throughput are displayed directly on the XCTU program. Testing with tree topology has the highest throughput of 0.31 Kbps and the lowest is 0.03 Kbps while the star topology reaches the highest number of 0.59 Kbps and the lowest is 0.51 Kbps. This is due to the delivery of the star topology directly to the Coordinator.
