Abstract

MANET can be used as an alternative communication solution because it is mobile, meaning that it does not have a fixed infrastructure. MANET implementation can use routing protocols, one example of which is Dynamic Source Routing (DSR). DSR routing protocol works when there is a request for sending packets from the source node to the destination node using two main mechanisms namely, route discovery and route maintenance. Route discovery occurs when the process of sending data from the source node to the destination node by performing a flooding mechanism to the neighboring node. If there is an excessive flooding mechanism, it can cause an increase in routing overhead on the DSR routing protocol. So to overcome these problems clustering is done by utilizing the Overhead Energy Efficient Cluster (COEEC) algorithm on the DSR routing protocol. The results of the addition of clusters in the DSR routing protocol with the COEEC algorithm can increase throughput performance by 43% and 31%, then an increase in the average end to end delay of 0.005% and 0.01%, then the packet delivery ratio parameter increases

Abstract

This study discusses the design of information technology enterprise architecture in the cooperation of Budi Karya. The main problem encountered is that the management still uses a bookkeeping system. The information obtained in each section has not been integrated with other, the IT management organization structure is not sufficient because there is no staff who have specialized IT experts, and require development in information technology. This was stated in one of the Budi Karya cooperation missions which read "Adopting the development of information technology and modern management systems". This study aims to produce process architecture, data, applications and technology that can be a reference for implementing all activities in cooperation of Budi Karya. This research uses the TOGAF (the Open Group Architecture Framework) which is a framework that has detailed methods and tools for developing and implementing enterprise architecture, with 8 architectural phases of vision, business architecture, information system architecture, technology architecture, opportunities and solutions, migration plan, implementation Governance, and architecture change management. Data collection is done by direct observation interviews and literature studies. The results of all these phases will produce a detailed framework of process architecture, data architecture, application architecture, and architecture in cooperation of Budi Karya Keywords: Enterprise, Architecture, Cooperation, framework, TOGAF

Abstract

In the world of music, music has several types of genre genres that can be grouped, there are music genre pop, rock, blues, slow, jazz, metal, dangdut and many more. And for each person must have a genre favorite that is different from one another, but to distinguish it does not need to play music files one by one especially if the number of music files is a lot. Therefore, computer software is needed to distinguish each of these genres in order to make it easier for users to distinguish and group the types of music according to their wishes automatically. By using the MFCC and KNN methods as a classification solution to classify several types of genre streams can be easily resolved. The results achieved from this study reached 52,4% with a K = 13 as the nearest neighboring point.

Abstract

Technologies that support wireless networks include WLAN (Wireless Local Area Network) and WPAN (Wireless Personal Area Network). One of the most widely used WLAN products today is IEEE 802.11n while the WPAN application is Bluetooth. Using the same frequency band in a coverage area can cause interference. Interference that occurs can be caused due to the use of 2 pieces of the same communication system, as well as different in a region. This study aims to determine how much influence interference has on the decline in the quality of a communication system with parameters measuring bandwidth, jitter, and packet loss. From the results of measurements and analysis shows that network quality is affected due to interference. Where if the network is free from interference around it, the network quality will be better, if the network experiences interference because using the same frequency band in the same coverage area can affect network quality such as reduced bandwidth value, increased jitter, and packet loss as well as channel usage and different channels. And the closer the distance of the access point that uses a different channel in a coverage area will cause the decreasing bandwidth value to increase the value of jitter and packet loss and vice versa. Keywords: interference, wireless, channel, bandwidth, jitter, packet loss.

Abstract

This paper presents the application of the Backpropagation method of the Artificial Neural Network algorithm in the case study to forecasting the amount of export value in NTB province. This forecasting process uses two scenarios, namely forecasting the amount of export value in NTB province and forecasting the amount of export value based on a commodity which then the forecasting results based on these two scenarios will be compared. Based on the results of the system testing that has been done, the best network architecture is obtained from 12-4-1, the best value of learning rate is 0.2 and the best number of epochs is 6000, which in the training device produces these variables resulting in an MSE value is 0,0034 and MAPE value is 8.52% and for the testing result MSE value is 0.0169 and MAPE value is 17.94%. Based on the results of forecasting with two scenarios that have been carried out are forecasting results that are negative. This is because the pattern of data used is not stable so that it can produce negative values.
