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

ARP (Address Resolution Protocol) is a protocol for addressing IP to the corresponding MAC Address in a local area network. Under normal circumstances a host on a local network will send ARP request packets that are broadcasted to obtain the MAC address of the destination host. When the host receives an ARP request addressed to it, the receiving host will send a unicast ARP reply packet to the sending host. Unfortunately, ARP does not provide an authentication mechanism for ARP replies intended for hosts that sent the packets. This enables every host on the network to fake ARP messages to poison the ARP cache of other hosts. ARP is vulnerable to attacks because it is a stateless protocol where ARP will accept and trust unsolicited replies so that spoof replies can be made to ARP requests. These spoofed replies can cause an ARP cache poisoning attack. ARP cache poisoning is an attack where an attacker sends a modified ARP packet to the local network. The modified packet causes the attacker's MAC address to be paired with the gateway's MAC address without the victim's knowledge that the entire traffic will pass through the attacker instead. In this study, handling of ARP cache poisoning attacks are done by analyzing the ARP packet traffic. ARP packages will be analyzed using wireshark and after a packet is considered to be a spoofed packet, prevention must be done. The types of treatment used in this study are Static ARP Entry and Persistent Arping. In this study, each type of treatment will be tested by measuring packet loss to the gateway when the ARP cache poisoning attack is in progress. The results between the two types of handling are an average of 0% packet loss when communicating to the gateway while an ARP cache poisoning attack is in progress using Static ARP Entry and an average of 53% packet loss while using Persistent Arping.

Abstract

MANET is a well-known self-configuring and infrastructure-less network. Each device connected to MANET is called a node, each of which has different characteristics in terms of mobility, which plays a role in the quality of a network. A node, when conveying a packet, requires routing process as a mechanism to determine the best path to let it reach its right destination. This research focused on comparing the performances of DSDV and FSR routing protocols when applied to both fixed and mobile nodes by testing three parameters, namely Routing Overhead, End-to-end Delay, and Convergence Time. Test scenarios were performed by varying the number of both moving nodes and non-moving nodes and varying the size of the packet conveyed. The results showed that the FSR protocol is more suitable to be applied in large-scale networks, with the values of convergence time, end to end delay, and routing overhead of 0.118 sec, 20.813 ms, and 22.748, respectively. Meanwhile, DSDV protocol is more suitable to be applied in small-scale networks, with the values of convergence time, end to end delay, and routing overhead of 0.1 sec, 31.607 ms, and 8.875, respectively. The results also indicated that the greater the packet conveyed the more significant the effect on the performance of a network because the data needs to be broken down into several segments, which are vulnerable to failure (Packet Loss).

Abstract

Fires often occur in the area of housing, Office space or in the Woods. The emergence of the fires themselves often leave casualties is not a little. Fire occurrence process itself can develop quickly or slowly depending on various factors such as the typically temperature, wind direction or weather based on material to burn. The issue was made of various fire alarm systems that are usually placed on building large and function gives a warning if the fire is large enough or usually the alarm will also be activated manually but the system does not tell you the location of the occurrence of fires. Based on the problems researchers make fire with point detection system sensor LM35 and flame sensor using algorithms K-Nearest Neighbor and a microcontroller, Arduino Mega as data processing. The workings of this system with sensor LM35 temperature detected on duty around the room and the sensor detects flame flame candles. If there is a fire then the system will process the calculation by the method of classification results obtained so KNN are used as the end result of this system. After the research is done, the results obtained from testing system has the accuracy of 80.55% and for process calculation of classification are obtained for 1428.83 ms.

Abstract

Roads are infrastructure that have an important role to support land transportation and support equitable development in an area., therefore road conditions must always be in good condition. In conducting monitoring, a survey is needed to determine the feasibility of road conditions. One survey method used is the International Roughness Index (IRI). PT. Hirfi Studio is a technical consultant company in Malang that provides transportation infrastructure survey services. PT. Hirfi Studio conducts surveys using direct visual observation method and then recorded manually on a survey form to be processed and converted into an IRI scale. The main tool used in conducting surveys are GPS, cameras and worksheets. The weakness of that processes are survey data in the paper form vulnerable to loss and damage, and processing data from the digitization of data to making maps takes a long time. Therefore, it is necessary to develop an automation survey on road condition using smart phone sensors to assist in conducting surveys. System development is done using software development life cycle (SDLC) waterfall model with object-oriented approach. The implementation of the application applies the model-view-controller (MVC) pattern in Codeigniter framework using HTML, PHP, CSS and Javascript programming language and uses database management system (DBMS) MySQL. In the testing phase, the unit testing value is 100% from 12 test cases, 100% validation of 46 test cases, and compatibility testing shows that the application can run on all desktop and smartphone web browsers.

Abstract

Seleksi Nasional Masuk Perguruan Tinggi Negeri (SNMPTN) is a selection of tertiary education based on the grade of subjects which each year experiences an increase in the number of participants so that they have a high level of competition. Counseling guidance teacher has the duty to predict student acceptance in attending SNMPTN. Problems arise when the number of students conducting guidance increases as the SNMPTN registration time approaches. Therefore, we need a system that can predict the likelihood of students being accepted through the SNMPTN pathway to ease the burden on counseling guidance teachers. One prediction algorithm is decision tree C4.5 that makes decision tress to describe rules. The data used comes from the value of subjects belonging to SMA Negeri 3 Malang alumni who have attended SNMPTN from 2016-2018 with a total of 681 data for the Natural Sciences majors and 90 data for the Social Sciences majors along with a list of students graduating SNMPTN in the same year. From the value data and the list of students passing the SNMPTN, the attribute used is only the attribute value of the subjects used in the 2019 SNMPTN along with the status of graduating or not students in joining the SNMPTN. The system is built in the form of a website that utilizes WEKA CLI for the prediction process. The black box testing-validation results show the use case and system functions are matched or valid. The system usability level generated by utilizing the system usability scale is 87.5 which is included in the "acceptable" category
