Abstract

SAMBAT Online is a concrete application of E-Government in a web-based platform for complaints provided by Dinas Komunikasi dan Informatika Kota Malang (Diskominfo Malang). An incoming complaint text will be categorized into various areas of the SKPD. With that being said, in order to make the job of the super admin easier in organizing and determining an SKPD category, as well to organize a complaint text and improve the time efficacy, a method of text classification is paramount. NW-KNN is an upgraded algorithm of the traditional KNN algorithm. Generally, the closest neighboring distance calculations will use Cosine Similarity with bag of words for feature extraction. Bag of words is a feature extraction that ignores the order of words of a sentence altogether. To improve the algorithm despite the deficiency, this research will use supporting method for feature extraction, which is called as N-Gram. The result in this research indicated that NW-KNN with neighboring value k = 3 and N-Gram with Unigram have the highest f-measure's value with 75.25%.

Abstract

Along with the rapidly excalation in the number of tourists as well as tourism which are located in Banyuwangi, problems arise from the tourists. With limited time, they would like to visit as many destinations without wasting time in traveling. However, another problem happened when the visitor and each visited destination has time windows or visiting time which has been established. From this issue, it needs a solution to solve the problems regarding with the tourism scheduling with the optimal time based on time windows from the tourists and the destinations. Generally, these problems called Vehicle Routing Problem with Time Windows (VRPTW). VRPTW problems can be solved with several optimization methods, including using hybridizing genetic algorithm and simulated annealing. Genetic algorithms (GA) will be used to explore the global optimum problem, while Simulated annealing (SA) will be used to exploit a local optimum problem. The fitness value approach optimal i.e. of 1.0616 obtained by using parameters of GA-SA on the size of population of 400, amount of generation by 800, combination of cr and the mr of 0.3 and 0.1, initial temperature of 0.9, cooling factor of 0.9, and the coefficient of acceptance of a new solution amounting to 200. Using these parameter values hybrid GA and SA outperforms separated GA and SA.

Abstract

Infants or so-called children is a group that have an important period in physical growth. Infants itself is categorized as a group of children between age 1 to 3 as a teddler group, and age 3 to 5 as a pre-school group. Some says children has a big role in order to attaining of growth success in the future for human, hence they call it as the golden age of living. Children's growth not only discribing as an increasing of body dimensions but also as the continuity of intake and nutrient needs. An indicator to know the children's health is by determining their nutritional status. Based on SK Minister of Health in Indonesia, they use a method called anthropometry to determining children's nutritonal status. While this method only reviewing 4 internal factors, there're some other factors which influence of children's nutritional status itself such as genetic, disease, education, knowledge, and income. Therefore Fuzzy K-Nearest Neighbor is used in this study as a classifiaction method that can determining children's nutritional status because this method using the data training as the knowledge to clasify and would adjust other factors of nutritional status itself right in the future. From the test results of the study, this system can clasify well with maximum accuracy of 84,37% when using 160 training data with k value = 4.

Abstract

Software Defined Network (SDN) has been developed over the last few years with the aim to simplify complexity in computer network. SDN's concept also developed to other kind of computer network including wireless network that really popular nowadays. The popularity of wireless network is caused by the simplicity and mobility that possible so there is no limitation for user's movement. But in the other hand, mobility also adds more challenges and really effected to the quality of wireless network performance. So, mobility is an important factor to considered when measuring wireless network performance. In this research, analysis of node mobility in SDN-wireless based or Software Defined Wireless Network (SDWN) has been done. The analysis is done by measuring network performance metrics specifically throughput, packet loss, and delay with Random Direction, Random Walk, and Random Way Point mobility model. The measurement is done at different velocity of node that is 5m/s, 10m/s, 15m/s, 20m/s, and 25m/s. The result shows that the highest throughput value 9.63 Mbps is gain in Random Direction at maximum velocity 25m/s, but it shows different result when the test is redone with 6.46 Mbps as highest throughput in Random Way Point that is caused by the instability of emulator. In the other hand, Random Way Point has the lowest packet loss 2116.2 packets at 25m/s and the lowest delay 51.056ms at 20m/s. The results show unstable value because of the emulator instability.

Abstract

Seiring dengan meningkatnya jumlah populasi manusia, sumber air bersih yang ada di bumi terus berkurang. Dampak yang diberikan akibat tercemarnya sumber air juga tidak dapat diremehkan. Beberapa dampaknya antara lain adalah menurunnya kadar oksigen yang ada di bumi dikarenakan tumbuhan tidak dapat berfotosintesis dengan baik, mengganggu kesuburan tanah, mematikan hewan-hewan yang hidup di dalam air dan masih banyak dampak lainnya. Salah satu sumber air di muka bumi ini berasal dari sungai. Untuk menjaga kualitas air agar tetap pada kondisi alamiahnya, perlu dilakukan pengukuran dan analisis terhadap air sungai tentang status mutu airnya. Pada penelitian ini digunakan 7 parameter pengukuran kualitas air sungai yang kemudian akan diklasifikasikan menjadi 3 kelas berbeda. Kelas klasifikasi dibagi menjadi tercemar ringan, tercemar sedang, dan tercemar berat.
