Abstract

LINE TODAY provides access to up-to-date news contents. Data on LINE TODAY are used to be able to do search engine feature. Query Expansion technique will be very useful if it is to be combined with search engine system where the queries inputted by users are combined with additional queries from the system. These additional queries will make queries generated by users more specific. In addition, users feedback (user judgement/explicit relevance feedback) assessing on each news can minimize ambiguous queries. The process begins with preprocessing technique consisting of several stages which are cleansing, case folding, tokenization, filtering, and stemming. And then, term weighting and cosine similarity. The next process is calculated using the Extended Rocchio Relevance Feedback method which is a traditional method from Rocchio Relevance Feedback to generate an additional queries. The results are obtained from implementation and testing process of Query Expansion on LINE TODAY with Extended Rocchio Relevance Feedback Algorithm resulted an average Precision value of 0.53308, Recall value of 0.81708, F-Measure value of 0.59553, and Accuracy value of 0.9574. The accuracy value obtained with Extended Rocchio Relevance Feedback method based on user judgement increase by 2% compared to automated search by the method of Rocchio Relevance Feedback.

Abstract

Raising laying hens are considered a promising opportunity in Indonesia because the demand for eggs in the country continues to increase in line with the increasing human lifestyle and need for animal protein. Based on data from the ministry of agriculture in 2017 there is an increase in chicken egg consumption during the year 1987-2017 of 3.57% per year with an average consumption of 6.63 kg / kap / th in 2017. On the other hand, raising laying hens is costly especially when it comes to livestock feed, which can cost farmers 60% -70% of production costs. One way to reduce the cost of purchasing feed is by optimizing the feed composition, with purpose of achieving an optimal feed composition that also meets the nutritional needs, all obtained with as minimal cost as possible. The optimization method used in this research is Genetic Algorithm with permutation representation, single-point crossover, reciprocal exchange mutation, and elitism selection. This study used 50 feed data material of laying chicken and its nutritional content. From the results of the tests, the population parameters obtained with the highest fitness value in the population of 500 and 800 with the average fitness value of 2.573591, the optimal generation of 100 generations with an average fitness value of 2.479726 and a combination of probability of crossover 0.5 and the probability of mutation 0.3 with the average fitness value 2.58459. The final result is the composition of laying chicken feed that meets the nutritional needs with minimal cost.

Abstract

Water pH is the most important aspect in the field of fisheries, especially in fish cultivation in ponds. PH monitoring problems, currently very much talked about one of them is weather changes that make the management sometimes forget or are lazy to check. So that the role of technology is needed that can help overcome the problem, to convey water pH data to managers remotely. IoT or the Internet of Things is a technology concept whose application can be used to help overcome these problems, where the system works is to connect physical objects with internet communication. IoT requires a protocol to run data transmission that functions as data transport from sensors to users on a network. The protocol used is MQTT (Message Queuing Telemetry Transport) where the protocol is expected to work in low bandwidth and unrealiable networks. The mechanism applied to the system used is publish-subscribe. With a sensor node on Arduino microcontroller as a publisher. Then the Raspberry Pi microcomputer is a server that functions as a broker, time control middleware and data storage. Subscriber as the data requester adopts from java language as a simple interface to the user so that it is easy to read. From the implementation that has been made, it is obtained the results of system testing that matches expectations and obtains protocol kinerja protokolnce which refers to the average latency and delay values ​​below 1 ms, which are 0.31 ms and 0.71 ms with a test time of 3x24 hours.

Abstract

Flood is a condition where water flow is higher than normal water level so it flooded the surrounding area. Floodwaves flow from upstream to downstream and interact with increasing water capacity of the estuary. Floods can occur due to high rainfall, overflow from the river, the destruction factor of Watershed (DAS). From that point on, a system that is able to forecast to make it easier to analyze the flood alert status in the future. Regression method used in this research is Fuzzy Time Series. The FTS method is a model usually used to forecast data in sequence. This research has a goal to forecast flood alert in Kambing Station DAS Brantas . The results of the test show the prediction of flood alert on the water level data (AWLR) that is in December 2016 got the error value (RMSE) of 2.89 and rainfall data (ARR) in February 2015 got the error value (RMSE) of 16.0. Both data resulted flood alert forecasting that shows Normal.

Abstract

Pervasive computing is one application of ubiquotous computing that is useful to facilitate the computer operation by minimizing the need for human interaction to the computer. While UDP Pervasive Multi Device is a UDP protocol developed using pervasive computing to be able to recognize the identity of other devices without the need for manual settings from the user. In this paper the UDP Pervasive protocol can be implemented on PC and NI myRIO devices using LabVIEW-based programs. UDP protocols are used because they do not require handshaking to reduce delay and smaller data sizes due to the absence of acknowledgment fields and sequence fields. Each device uses dual state machine system design that has function for detecting other devices automatically and as an application of using other devices address. When the program is first executed, the device broadcasts to all devices. Then the device does listening to receive broadcast data or replies from broadcast. When receiving broadcast data or replies then the device checks the duplication of the device and stores it. The device then sends a reply when receiving broadcast or back to listening. By using the same state machine to detect all device, the device can recognize other devices more than one on the same network. The results of the test obtained that all state-based testing succeeded 100%. Discovery time averaging 0.202754 seconds for 1 myRIO and 0.303201 seconds for 2 myRIO. Sending data delay from PC to myRIO not more than 2 second.

Abstract

Cultivation of melon plants requires optimal care and appropriate environmental conditions, as they are susceptible to pest and disease infections. This leads to crop failure due to errors from the handling and selection of the pesticides used in tackling them. The agricultural extensions at this time are still have some difficulty to identify the diseases that attacked the melon plants despite the clear differences between each melon plants and determine the solutions for handling and to eradicate the disease. Based on the said problems, a melon plants' diseases diagnosing system is designed. The Promethee method can be used as a decision-assisting method by comparing the symptoms of one disease with another using the criteria of preference. In the melon plants' diseases diagnosing system using Promethee method's main functions are calculating the value of paired comparison deviation for each disease and calculate the value of stream flow in the form of Entering Flow, Leaving Flow, and Net Flow. The melon plants' diseases diagnosing system using 30 test data resulted in an accuracy rate of 86.67% by using Usual and Gaussian preference criteria. The difference in the level of accuracy in each type of preference is determined by the weight of each symptom from each disease as well as the indifference threshold and the preference threshold used in the calculation.
