Abstract

Natural disaster is an event that can cause damage to communication network's infrastructure in a region. Therefore, a network technology that is able to run independently without the infrastructure of communication and internet networks; such as BTS, router, or access point, is required. The technology is called Mobile Ad-Hoc Network (MANET). MANET is a wireless network consisting of a set of mobile nodes that communicate in a multi-hop manner inside a dynamic topology without depending on a supporting infrastructure. MANET routing protocols are generally classified into three types, such as reactive, proactive, and hybrid routing protocols. These three types of routing protocols have different algorithms in route search methods. Among the three types of routing protocols, there are AOMDV, DSDV, and ZRP. This research was propsed to compare the performance of three different types of routing protocols, such as AOMDV, DSDV, and ZRP when simulated in different scopes. Simulations were performed using Network Simulator 2 and measured by four parameters such as throughput, end-to-end delay, packet delivery ratio, and normalized routing load. Based on the tests that were conducted in different range area and number of mobile nodes scenarios, it can be concluded that AOMDV has the highest average packet delivery ratio and throughput value. On the other hand, it was found that the best average value was obtained by DSDV protocol during the measurement of end-to-end delay and normalized routing load.

Abstract

Checking the employees attendance is an important matter for every institution or company to see their own employee performance. Each instituion or company must have their own way to check the employees attendance, such as using a paper, smartphone application, RFID (Radio Frequency Identification), and biomentric technique. Those kind of ways are really making the company easier to check the employees attendance, but there is a flaw, for example is on the fingerprinting system when using the fingerprint, sometimes the fingerprint can not be detected by the system, moreover an employee should reach a specific location to make a presence. This sometimes make the employees to procrastinate or late to make a presence. As a result, the employees often forget and do not make a presence. From the problem, this reasearch is made to make a presence system for employees using a wifi fingerprint, wifi fingerprint means a MAC address which is caught by microtic router when a smartphone is connected. System will read the MAC address and interface of the router mikrotik through the API for RouterOS, then save it into the database, and compare it with the MAC address already in the database, so when it happens, an employee will be considered as present and the location of an employee will be known based on a place where a smartphone is connected. The testing result of functionality and performance shows the all functions on system run well and the time that needed by a system to read from a router has an average below of one second and the time for system to detect the presence including the employees location is about five seconds.

Abstract

Cost calculation is one of the decisive factors in making software. A small cost estimation will result in low quality produced software, otherwise a large cost estimation will result in a waste of expenditure. Both of these factors will potentially result in software project failure. There are several techniques and software cost estimation models that are classified into algorithmic and non algorithmic. Each has advantages and disadvantages, but there is no best techniques for all software development conditions. One of the most popular algorithmic methods for estimating software development costs is COCOMO II. COCOMO II proves to be a flexible model and has precise accuracy to use in cost estimates. Therefore, research conducted on the software house Jasa Web Malang uses COCOMO II method, especially post architecture submodel in estimating the cost of one of their projects. The goal is that this method can be accepted and applied to the software house. The result of this research is the estimated cost used by using COCOMO II method is smaller than the cost incurred by Jasa Web Malang and the cost estimation method using COCOMO II with post architecture submodel can be applied to software house Jasa Web Malang if the software house get flexible clients in waiting for the decision of the value of the system because to get the price of the System by calculating using COCOMO II method takes longer time than using guesstimate method.

Abstract

One of the criteria in applying mobile navigation is the ability of mobile device to continuously monitor point of access from user, but in monitoring the point or the object always changes due to the movement of user. The changes occurring are known as split nodes. There is a method used to manage split nodes that is KNN search, but the performance is still not satisfactory. Another proposed method is the Voronoi Continuous K Nearest Neighbor (VCKNN) algorithm that uses the Voronoi diagram to help manage split nodes. The use of the VCKNN algorithm is supported by Dijkstra's algorithm in searching for split nodes within the Voronoi polygon. In this research will be done comparison between VCKNN and Dijkstra algorithm in managing split nodes. This is done to get algorithms that have the best performance in managing data on segmentation, runtime and split nodes. This research will take a study area of ​​Malang Raya. Selection of Malang Raya as a study area due to unstructured road network structure neat, so it can know the performance of the proposed algorithm. From this research, the results obtained using VCKNN algorithm occurs the performance improvement compared to Dijkstra's algorithm. Increased performance occurs due to the decrease in the number of split nodes produced. The decrease of split nodes that occur using the VCKNN algorithm based on the use of administrative boundaries sub-district as the interest point resulted in the decrease of split nodes by 92.4%. With the result of this research for Malang Raya road network condition, VCKNN algorithm yield satisfying result.

Abstract

Agriculture still plays an important role in the economy in the Batu City. In addition to horticultural plants, the Batu City is also a producer of rice plant though not many areas planted with rice. According to the results of the interviews from the Department of Agriculture and Forestry of Batu City, within one year, the land planted with rice only once or twice that should be done 3 times. It is because the farmers do not know the land is actually appropriate or not for rice plant. Department of Agriculture and Forestry of Batu City currently does not yet have data related to whether the land is actually appropriate or not for planting rice. The data is required, so it can be used as a reference in managing agricultural land. To get the results of the land suitability, this study will apply the methods of GIS-MCDA (Multi Criteria Decision Analysis), which used the 9 criterias that affect the suitability of the land and the results will be applied in Geographic Information Systems (GIS) based on the web. GIS based on the web (Web-GIS) is built according to the architectural design. Web-GIS architecture consists of 3 layers, i.e. the Client Layer, Service Layer, and Layer Support. Based on the results of land suitability analysis, this research get 4 results of land suitability class i.e., S1, S2, S3, and NS. Total area of suitability class S1 is 739.42 ha with percentage 3.7%, total area of suitability class S2 is 7375.91 ha with percentage 37%, total area of suitability class S3 is 3706.20 ha with percentage 18.6%, and total area of suitability class NS is 8120.02 ha with percentage 40.7%.
