Abstract

Big Data is a collection of data with a large and complex size, consisting of various data types and obtained from various sources, overgrowing quickly. Some of the problems that will arise when processing big data, among others, are related to the storage and access of big data, which consists of various types of data with high complexity that are not able to be handled by the relational model. One technology that can solve the problem of storing and accessing big data is Hadoop. Hadoop is a technology that can store and process big data by distributing big data into several data partitions (data blocks). Problems arise when an analysis process requires all data spread out into one data entity, for example, in the data clustering process. One alternative solution is to do a parallel and scattered analysis, then perform a centralized analysis of the results of the scattered analysis. This study examines and analyzes two methods, namely K-Medoids Mapreduce and K-Modes without Mapreduce. The dataset used is a dataset about cars consisting of 3.5 million rows of data with 400MB distributed in a Hadoop Cluster (consisting of more than one engine). Hadoop has a MapReduce feature, consisting of 2 functions, namely map and reduce. The map function performs a selection to retrieve a key, value pairs, and returns a value in the form of a collection of key value pairs, and then the reduce function combines all key value pairs from several map functions. The results of the cluster quality evaluation are tested using the Silhouette Coefficient testing metric. The K-Medoids MapReduce algorithm for the car dataset gives a silhouette value of 0.99 with a total of 2 clusters.

Abstract

Salah satu cara mengamankan suatu file agar tidak berubah-ubah pada sebuah teknik forensik digital adalah dengan cara membuat cloning suatu devices atau menyalin keseluruhan file pada suatu devices (smartphone) kedalam bentuk suatu file yaitu dalam bentuk file Image yang bisa dibuka dimanapun dan dengan tools apapun yang mendukung terbukanya file Image hasil cloningan suatu devices. Penggunaan tools forensik digital khususnya forensics mobile tergantung dari pilihan examiner dalam melakukan ekstraksi data dari file Image tersebut. Metode National Institute of Standard and Technology (NIST) digunakan dalam penelitian ini dengan tahapan seperti Coolection/Preservation, Examination, Analysis dan Reporting. Hasil ekstraksi yang kemudian dianalisa dengan menggunakan metode NIST didapatkan hasil dari penggunaan tool forensik seperti Belkasoft Evidence Center berhasil melakukan ekstraksi data dari sebuah file Image smartphone android Samsung GT-S5282 dengan tingkat akurasi ekstraksi data sebesar 66,66% dari variabel yang sudah ditentukan dan juga ditemukan file panggilan dan pesan yang sudah terhapus didevices pengguna. Tool Magnet AXIOM mendapatkan tingkat akurasi dari smartphone yang sama sebesar 55,55% dari variabel yang sudah ditentukan dan dalam proses analisis ditemukan banyak sekali file carving dalam devices pengguna. Hasil penelitian ini dapat disimpulkan bahwa tool Belkasoft Evidence Center lebih memiliki kinerja yang baik daripada tool Magnet AXIOM dalam proses exstraksi data dari sebuah file Image smartphone android. Hasil penelitian ini bisa dijadikan sebagai rujukan bagi para examiner dalam menentukan tool forensic digital yang mumpuni dalam menangani sebuah kasus kejahatan digital.

Abstract

The increase in online-based services makes a security system for server computers increasingly needed. A server computer is a device that must always be available to be accessed anytime and anywhere. Some of the security systems needed for server computers include security for ssh port access for remote server access needs and a security system to protect servers from Denial of Service (DoS) attacks which can make the server down and completely inaccessible. In this study, a security system is proposed for a server computer with the Linux CentOS operating system on a port 22 secure shell(ssh) access system using the port knock method and a security system to prevent Denial of Service (DoS) attacks on server computers using the RST Cookies method. The simulation results from the port 22 Secure Shell (SSH) access experiment for the server computer can work well where port 22 Secure Shell(SSH) will remain closed and cannot be accessed carelessly except by accessing several ports first according to predefined port knocking rules. Likewise, the implementation of a security system with the RST Cookies method works very well to prevent Denial of Service (DoS) attacks and can still keep the server accessible with a good response time of under 1 ms

Abstract

ArsyaNet, a local internet service provider, strives to deliver fast and reliable internet access to its customers. This study aims to implement a web-based Geographic Information System (GIS) for customer mapping and network development prioritization using the Analytic Hierarchy Process (AHP) method at ArsyaNet. Leaflet is employed to map the distribution of ArsyaNet customers within the RT/RW network in the Pringgasela District. The main objective of this research is to accurately and efficiently map the distribution of internet customers to support optimal network development. By integrating AHP into the GIS, customer preferences and other relevant factors such as access speed, service quality, and infrastructure needs in specific areas will be considered in determining the priority locations for network development. The AHP method allows for the grouping of customers based on their preferences and determining locations by considering weights on each relevant aspect. Integrating Leaflet into the GIS enables accurate and interactive mapping results using a lighter map compared to the Google Maps API. This research is conducted to enhance the quality of internet services provided by ArsyaNet by better understanding the needs and preferences of customers in selecting internet service providers and their customer distribution.

Abstract

The increasing need for transportation, especially motorcycles, has led to many illegal methods and criminal actions by individuals committing motorcycle theft. Fundamentally, security and safety are the primary concerns motorcycle users must pay attention to on the road. Many vehicle users neglect safety while riding, such as inappropriate driving. Some actions endanger themselves and other drivers, like using a cell phone while riding, causing the rider to lose focus. Therefore, this research offers a solution as a microcontroller-based security and safety system aimed at minimizing motorcycle theft and improving riding safety. The solution from this research is to produce a microcontroller-based technology utilizing RFID for security, touch sensors, and push buttons for safety when the rider does not follow proper riding procedures. The Research & Development method is used in this research, with five stages: analysis, design, development, implementation, and evaluation. The results of this study are a prototype of a security and safety system based on an Arduino Uno microcontroller as the control center. Regarding security, the vehicle starts only with registered access in the control center, which is then placed on the RF reader installed on the car. From the test results, using an e-KTP as the vehicle access medium successfully started the motorcycle with a 0% error rate from 10 trials. Regarding rider safety, using a touch sensor to test the number of passengers was successful, with an 80% success rate from 10 trials. The push button succeeded with a 100% success rate from 10 trials when users did not position their hands on both motorcycle handles (bars) and successfully triggered the alarm when the rider was not riding correctly.
