Abstract

Penelitian ini bertujuan untuk merancang sebuah sistem keamanan jaringan komputer dengan menerapkan Snort Intrusion Detection System (IDS). Sistem keamanan jaringan yang dibangunmengintegrasikan antara Intrusion Detection System (IDS), Database System, dan Monitoring System. Dalam skema pengujian, sistem terdiri dari dua jenis, yaitu server dan client. Server berfungsi sebagai target serangan dan sekaligus digunakan untuk melakukan pemantauan terhadap jaringan. Sedangkan client berfungsi sebagai intruder (penyusup). Metode seranganyang diterapkan pada lingkup pengujian adalah Port Scanning dan Denial of Service (DoS). Dari hasil pengujian yang telah dilakukan, Snort-IDS mampu menganalisis paket-paket yang melewati jaringan dan berusaha menentukan apakah terdapat paket-paket data yang berisi aktivitas mencurigakan atau tidak. Dari data hasil pengujian yang diperlihatkan oleh Basic Analysis and Security Engine (BASE), didapatkan bahwa intruder melakukan port scanningsebanyak 28%, TCP attack 62%, UDP attack sebanyak 1%, dan ICMP attack sebanyak 9%. Unique Alerts yang dihasilkan terbagi kepada dua kategori yaitu, unclassified sebanyak 28%dengan jumlah 74, dan attempted-dos sebanyak 72% dengan jumlah 189.Kata kunci: Jaringan Komputer, Keamanan Jaringan, Sistem Deteksi Penyusupan, NIDS,Snort, Denial of Service (DoS).This study aims to design a computer network security system by applying the Snort Intrusion Detection System (IDS). Network security system that is built integrates the Intrusion Detection System (IDS), Database System, and Monitoring System. In the test scheme, the system consists of two types, namely server and client. The server functions as a target of attack and is simultaneously used to monitor the network. While the client functions as an intruder. The attack methods applied in the test scope are Port Scanning and Denial of Service (DoS). From the results of tests that have been done, Snort-IDS is able to analyze packets that pass through the network and try to determine whether thereare data packets that contain suspicious activity or not. From the test data shown by the Basic Analysis and Security Engine (BASE), it is found that intruders do port scanning as much as 28%, TCP attacks 62%, UDP attacks as much as 1%, and ICMP attacks as  much as 9%. The resulting Unique Alerts are divided into two categories, 28% unclassified with 74, and 72% attempted dosage with 189.Keywords: Computer Network, Network Security, Intrusion Detection System, NIDS,Snort, Denial of Service (DoS)

Abstract

Pada teknologi informasi yang semakin cepat seperti saat ini perkembangan ilmu pengetahuan dan teknologi terus maju dengan pesatnya. Hal ini menuntut setip usaha menajual jasa atau barang harus berpikir lebih untuk dapat bersaing dalam merebut para konsumen, dengan layanan yang baik untuk dapat memenangkan persaingan pasar. Hal ini telah mendorong berbagai perubahan–perubahan yang selalu sesuai dengan teknologi informasi, perubahan-perubahan tersebut perlu dikaji dan dianalisa oleh perusahaan–perusahaan supaya dapat menjalankan roda usahanya. Salah satunya pemanfaatan kemajuan teknologi komputer yang pada masa sekarang maupun yang masa akan datang sangat dibutuhkan, karena disadari bahwa komputer merupakan alat bantu dalam menyelesaikan pekerjaan manusia secara cepat dan akurat. Suatu pekerjaan yang memakan waktu berhari-hari atau pekerjaan yang berulang-ulang dengan jumlah yang cukup besar dan menyita waktu dan biaya, oleh komputer dapat dilaksanakan beberapa menit saja. Disamping itu komputer juga dapat menyimpan data, memperbaiki data dan mengambil informasi yang dibutuhkan, data atau informasi tersebut disimpan dalam bentuk file, adanya alat bantu komputer tersebut maka pemecahan masalah akan dapat diatasi.Kata kunci : Aplikasi, Sistem Informasi, Pemesanan, UPI Convention Center, PHP, MySqlIn the increasingly fast information technology as it is today the development of science and technology continues to advance rapidly. This requires every business selling goods or services must think more to be able to compete in seizing consumers, with good service to be able to win market competition. This has led to various changes that are always in accordance with information technology, these changes need to be reviewed and analyzed by companies so that they can run their business. One of them is the utilization of computer technology advances, which are now and in the future are very much needed, because it is realized that computers are a tool in completing human work quickly and accurately. A job that takes days or repetitive jobs with a large enough amount and takes up time and money, by the computer can be done in just a few minutes. Besides that the computer can also store data, improve data and retrieve the information needed, the data or information is stored in the form of files, the existence of these computer aids will solve the problem can be overcome.Keywords: Application, Information System, Ordering, UPI Convention Center, PHP, MySql

Abstract

The Panai dialect of Malay is the mother tongue used by the speaking community in four sub-districts in Labuhanbatu Regency. The reduced number of native speakers who are skilled in the Panai Malay dialect can threaten the sustainability of this language. Efforts to preserve the Panai Malay dialect must be made to avoid extinction. One way that can be done is to document vocabulary in the form of a translator application. This study aims to create an application translator for the Panai-Indonesian dialect of Malay by applying natural language processing. As for the potential users of this application, they are the people of Labuhanbatu in general, especially those in the four sub-districts previously described. The stages of the research method used were: requirement analysis, design, implementation, testing, and maintenance. This research focuses on technology for improving information and communication technology content in the context of local wisdom (culture and language) in Indonesia. The focus of this research is in line with the Strategic Plan (RENSTRA) of Labuhanbatu University, which covers the fields of information and communication technology and cultural arts. From the results of this study, it is hoped that local wisdom in Labuhanbatu Regency will be maintained as social capital for the resilience of the Indonesian nation.

Abstract

One of the most popular e-commerce sites in Indonesia is Shopee. As the largest marketplace application in Indonesia, Shopee provides product and service review features to users on the Google Play Store. The review feature is very helpful to find out whether user reviews are positive or negative. Having user reviews will help Shopee improve its services. To identify a very large number of user reviews, it is not possible to do it manually by reading them one by one. This process will take a very long time and is not effective. Therefore, we need a method that is able to identify reviews from users more effectively and efficiently. This research aims to conduct sentiment analysis of user reviews of the Shopee application on the Google Play Store by applying the Support Vector Machine algorithm. The research stages carried out started with dataset collection, dataset labeling, preprocessing, TF-IDF weighting, classification, and evaluation. From the research results, accuracy was 70.88%, precision was 49.49%, recall was 52.55%, and F1-score was 49.84%. From these results, it can be concluded that the performance of the support vector machine algorithm in classifying the sentiment of user reviews of the Shopee application on the Google Play Store is quite good.
