Abstract

Indonesia Power Suralaya is one of the subsidiary company of PT PLN (Persero) located in Cilegon City, Banten Province. PT. Indonesia Power Suralaya has six divisions, namely Finance, Public Relations, Administration, Information Systems (SIS) 1-4 Unit, and 5-7 Unit. Division of SIS has problems in asset management of asset data collection, borrowing goods, returning goods, and treatment goods. Division of SIS is using Microsoft Excel to asset data collection. Division of SIS has difficulties in monitoring of incoming goods and outgoing goods. Division of SIS has constraints in searching for users of previous items because data management of borrowing goods and returning goods is still done by writing on a notebook. Division of SIS hasn't provided data management to treatment of goods. PT Indonesia Power Suralaya allows employees to borrow goods. Employees have difficulties in status monitoring of borrowing goods and returning goods in office. This research has developed an asset management system to overcome these problems. This system uses web technology that allows the system to be accessed easily by using the web browser. This system is expected to help PT. Indonesia Power Suralaya in asset management. This research was using Object Oriented Analysis and Design (OOAD) method and Object Oriented Programming (OOP) method for developing an asset management system. This system has been tested using white box testing for unit testing and integration testing and also using black box testing for validation testing.

Abstract

Code Smell is a structural pattern part of a software program code that has a bad design. The code structure pattern that contributes to excessive coupling is code smell feature envy. Feature Envy occurs because of the high coupling of the inaccuracy of class member placement within a class. Incorrect class member placement will affect the program code structure if a change is made. However, the different patterns of perceptions of each programmer resulted in the difficulty of measuring the code smell feature envy. This study aims to equate the perceptions of programmers by building an application system that can detect the envy smell feature code automatically so that it can simplify the implementation of clean code smell feature envy. The application system for detecting the smell feature envy code was developed based on feature envy factor as a reference in measuring and calculating its value. This system has been tested using the White box method for unit testing and integration testing and then the Black Box method for validation testing with pass status or valid for each method that has been applied. This system also gets 100% accuracy rate for each project tested.

Abstract

Traditional food and snacks are typical of ancestors usually used for events or traditions. Some people consider that traditional food and snacks are obsolete, so that more traditional food and snacks are left behind by the people, and begin to shift to modern life, whereas traditional snacks themselves are one form of ancestral heritage that must preserved by next generation. Making system that can identify traditional types of food can be done using digital image processing. In this study, the image data used the result of image after segmentation with three types of data on testing, that is 300 images of the best segmentation result, 300 data of images with the amount of data each class is almost same and 400 data of images with the best segmentation results. Image feature used Hue Saturation Value (HSV) that contains mean, standard deviation, skewness and curtosis each color dimensions. Classification using the Fuzzy k-NN method and k-Fold Cross Validation. The test results based on values of k (k-Fold) and k (k-NN) obtained highest average accuracy at 53.33%. The test results also show that high color similarity between classes, poor image quality data and uneveness amount of data makes the test result decreased.

Abstract

The home security system is one of the features that must be owned and considered for every homeowner who wants to have a home that is safe from theft and avoid other unwanted security disturbances. So we need a support system that is able to increase home security. In this study, the system created uses the face as security data. This system uses a webcam as a face image taker and is integrated with the Raspberry Pi. This system will apply the buzzer, LED, solenoid door lock and SIM800L modules as outputs of the system. This system uses HaarClassifier to detect faces, then Histogram of Oriented Gradient and k-Nearest Neighbor for face recognition. First the system will take the image captured by the webcam, then use face image detection with Haar-Classifier, then the facial image will be extracted using the HOG feature. After the face feature value is obtained, it will then be classified using the k-Nearest Neighbor algorithm. From the results of testing the accuracy of face detection is the best accuracy of 100% at a distance of 40cm. The results of the accuracy of face recognition at a distance of 40cm in total are equal to 87.5%. For testing the accuracy of integration between software and hardware produces an accuracy rate of 100%. The average time needed for the face recognition process is 13,28839 seconds.

Abstract

Hadoop is a distributed system use to process large amounts of data whith is stored in several groups of compute. Hadoop has three main connected component namely hadoop distributed file system, mapreduce and Yet Another Resource Negotiator it also called YARN. YARN is used as a resource which regulases cluster processing and hadoop scheduling. There are several scheduling algorithm on Hadoop including capacity scheduling and for share scheduling. Capacity scheduling algoritm is an algorithm that can make schedule in YARN by executing job first. Each scheduling has priority for resource and cluster while slot in scheduling idle, so the scheduling can be use directly even it has not priority. Fair share scheduling algorithm is an algorithme that runs at each hadoop cluster so that cluster on each job are equal. This research was hold to optimize performance of fair share algorithme and to compaire performance of these algorithme wit capacity scheduling using parameters job fail rate, responce time and throughput. Based on the results of testing that has been do. In the fair share algorithm the difference in the average value of failrate parameters is 0.623% better than the capacity scheduling algorithm, the responce time parameter is 5.44 minute better than the capacity scheduling algorithm and the throughput is 0.596 Job/minute better than the capacity scheduling algorithm so the average value the fair share algorithm is better than the capacity scheduling value.

Abstract

Research on wheeled robot navigation control has been developed by using human commands directly, one of which is by using hand gestures. The aim is to overcome problems related to the navigation control system. The implementation of an inertial measurement unit (IMU) sensor was developed on the hand gesture control device to detect all forms of movement produced. However, the measurement results by sensors are often inaccurate. The Kalman Filter algorithm is the ideal approach to optimize the estimation of the inaccuracy of signals produced by sensors. Manually tuning the covariance filter is done by changing the matrix covariance noise process with the try and error method based on the predetermined test scenario. The Kalman Filter signal test results show the determination of the variable Q_angle = 0.001, Q_bias = 0.003 and the value of R_measure = 0.03 is optimal in estimating measurements to minimize the effects of noise.
