One form of artificial intelligence is the automatic detection of images. so the system can determine precisely the type of image or it can be called computer vision. Water guava fruit is a fruit that is often encountered in Indonesia, but many of the water guavas in the community are of poor quality, thus detrimental to consumers. Therefore we need a system that can detect the quality of the water guava. The Principal Component Analysis (PCA) algorithm and the k-nearest neighbor (k-NN) algorithm can be combined to do this job. PCA is an algorithm that can convert to a group of data that is initially correlated into uncorrelated data (Principal Component). The number of Principal Components generated is the same as the original data, but can be reduced to a smaller amount and is still able to represent the original data well. Meanwhile, k-NN is a method for classifying objects based on learning data that is closest to the object. The research model used in this research is a prototype, and the development tools used are UML. In making the water guava quality detection system, the MATLAB programming language is used, and the test uses the blacbox method. The result of this system is that the system is able to produce output in the form of quality classification of water guava fruit automatically.Keywords: Computer vision, PCA, k-NN

ABSTRACTThe flow of information that moves uninterruptedly is one of the needs of an organization, the internet makes information can flow quickly to support the activities of its users. However, the quality of the internet in Indonesia has not been so good because there is still a breakdown of internet services from ISPs to users. It is very important for the organization to maintain its activities to keep running normally when internet services are not available. One technique that can be used to overcome this problem is fail over against internet access, so that if one internet source is down it will automatically be switched to another internet source. Fail over is a technique that uses more than one internet gateway, where one link can be used as the main gateway and the other becomes a backup link. And the method that can be used is the recrusive gateway by defining check-gateways and differentiating distance values on each routing rule. And the system development method used is PPDIOO which has 6 stages, namely: prepare, plan, design, implement, operate, and optimize. The results of this research will be able to guarantee the availability of the internet in an organization, so that it can increase the productivity of an organization.Keywords : failover, recrusive gateway, mikrotikABSTRAKArus informasi yang bergerak tanpa terputus merupakan salah satu kebutuhan dari sebuah organisasi, internet membuat informasi dapat mengalir secara cepat untuk menunjang kegiatan para penggunanya. Akan tetapi kualitas internet di Indonesia belum begitu baik karena masih terjadi putusnya layanan internet dari ISP ke pengguna. Sangat penting bagi organisasi untuk menjaga kegiatan – kegiatannya untuk tetap berjalan normal ketika layanan internet sedang tidak tersedia. Salah satu teknik yang dapat digunakan untuk mengatasi masalah tersebut adalah fail over terhadap akses internet sehingga apabila salah satu sumber internet putus maka secara otomatis akan langsung di alihkan ke sumber internet lain. Fail over merupakan teknik yang menggunakan lebih dari satu gateway internet, dimana salah satu link dapat dijadikan sebagai gateway utama dan yang lain menjadi link cadangan. Dan metode yang dapat digunakan adalah recrusive gateway yaitu dengan mendefinisikan check-gateway dan membedakan nilai distance pada masing-masing rule routing. dan metode pengembangan sistem yang digunakan adalah PPDIOO yang memiliki 6 tahapan, yaitu: prepare, plan, design, implement, operate, dan optimize. Hasil dari penelitian ini nantinya dapat menjamin ketersediaan internet pada sebuah organisasi, sehingga dapat meningkatkan produktivitas kinerja sebuah organisasi.Kata kunci : failover, recrusive gateway, mikrotik

Publisher : UNIVERSITAS INDO GLOBAL MANDIRI

DNS is made to facilitate users in accessing a website with a domain without having to continually update the files host.txt.DNS was developed in 1983, every user accessing a website using a domain name through a browser, will be routed by the router to a public DNS serverto get a web address in the form of ip address.It takes time for DNS servers to reverse and lookup for translate domain names into ip addresses and vice versa.By creating a local DNS server as a cache,then it can be applied forwarding technique on DNS Server,so the time required to find the web server address of a destination website becomes faster. In addition to minimizing query time by implementing a local DNS server, can also be filtered against a particular domain name even though using a secure protocol like httpsby creating a zone for the web address you want to filter. So the use of the Internet becomes more useful. In this study the software used linux debian 8 as the operating system, and BIND9 as the software that runs the function of DNS Server.Keywords:Forwarding DNS,BIND 9, Debian 8

AbstractThere are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype. The results of this study are all aspects of data security can be achieved, including when passing through the process of sending data through media such as the internet.Keyword: Steganography, Criptography, Prototype.AbstrakAda beberapa aspek keamanan data yang harus dijaga, seperti: otentikasi, integritas, non repudiation, otoritas, kerahasiaan, privasi, dan kontrol akses. Salah satu bagian yang rentan dari keamanan data adalah ketika mengirim data ke tujuan. Pada saat pengiriman, penyadapan data dapat terjadi, sehingga orang yang tidak berhak mendapatkan informasi tersebut dapat mengetahuinya. Oleh karena itu, suatu informasi perlu diamankan sehingga hanya orang yang memiliki hak akses yang dapat mengetahui atau mendapatkan informasi tersebut. Dan untuk menjaga kerahasiaan informasi, salah satu caranya adalah dengan memasukkan data ke objek lain, sehingga orang lain tidak menyadari jika objek tersebut berisi data atau informasi penting. Metode persembunyian ini juga dikenal sebagai steganografi, dan kriptografi ditambahkan untuk memperkuat keamanan data, yaitu ilmu dan seni untuk menjaga kerahasiaan pesan dengan menyandikannya dalam bentuk yang tidak dapat dipahami. Metode yang digunakan dalam steganografi adalah Least Significant Bit (LSB), algoritma yang digunakan dalam kriptografi adalah Advanced Encryption Standard (AES), dan metode pengembangan perangkat lunak yang digunakan adalah prototipe. Hasil dari penelitian ini adalah semua aspek keamanan data dapat dicapai, termasuk ketika melewati proses pengiriman data melalui media seperti internet.Kata kunci: Steganografi, kriptografi, Prototipe

The need for the availability of information is currently very high, especially in the conditions of the COVID-19 pandemic, all organizational activities are carried out online. Human dependence on the role of information technology is increasing and this has consequences for long distance communication between devices, which requires users to be authenticated for access rights granted by the system. The problem that arises is the security of data travel during the authentication process, where there is the possibility of leaking account information. This is because communication is done on a public network while accessing resources that require privacy. Therefore we need a network connection that is safe and efficient. Virtual Private Network (VPN) is a network communication technology that allows you to connect to public networks safely and quickly. The VPN used in the solution to this problem is Wireguard. Wireguard is a VPN protocol built with advanced cryptography and makes it extremely fast and secure. The method used by the author in developing this system is PPDIOO which consists of, Prepare, Plan, Design, Implement, Operate, and Optimize. And also some supporting tools for the development of the system Unified Modeling Language. By using Wireguard VPN, the expected result is the security of the data sent to be more secure and can connect two remote networks privately using the public internet.Keywords : VPN, Wireguard, Mikrotik

Domain Name System (DNS) enables users to access websites via domain names, offering convenient navigation. However, criminals can exploit this convenience to redirect connections from user devices to fake servers for a variety of purposes. A form of attack known as DNS cache poisoning exploits vulnerabilities in the Domain Name System (DNS) to redirect connections from a legitimate website address to an illegitimate one. As a consequence of the fact that users of networked systems are typically unaware that they are accessing an illegitimate site, this attack can have a particularly damaging impact. Such incidents can give rise to several issues, including the theft of data, the distribution of malware, and other security threats. To address this issue, this study employs a firewall in conjunction with DoH (DNS over HTTPS) and the utilization of registered certificates. The Domain Name System over HTTPS (DoH) protocol encrypts DNS requests and responses, preventing third parties (such as attackers who manipulate DNS) from reading or modifying DNS requests. The data employed in this study is derived from a review of existing literature. Furthermore, this study employs the PPDIOO model (Preparation, Planning, Design, Implementation, Operation, and Optimization) for the development of the network. Furthermore, the Mikrotik RB951ui-2Hnd routerboard is employed in this study. The outcome is the implementation of a multifaceted security strategy that effectively mitigates DNS cache poisoning attacks by 100%, while simultaneously reducing CPU usage to 11.5%. This approach enhances the security and reliability of user search activities on the internet.

As people become more dependent on information technology, the need for Internet availability increases. Various types of devices are connected to the network, increasing the convenience of using information technology. However, this convenience can often be disrupted by attacks on the network infrastructure, one of which is a DHCP Starvation attack. The Dynamic Host Configuration Protocol (DHCP) is a client-server-based protocol used to automatically assign or obtain IP addresses for client computers or other network devices. Mitigating DHCP Starvation attacks is one form of protection for users. The impact of this attack is that the attacker can become one of the hosts on the network and perform a man-in-the-middle attack, so the impact of information leakage can occur. In addition, it is necessary to know the impact on router resources when a DHCP Starvation attack occurs, so that network managers can calculate how much resources are needed. The author uses a Filtering method based on Mac address es, ARP, and alerts on the Mikrotik router. In addition, the PPDIOO method is also used to develop this system, which consists of preparation, planning, design, Implementation, operation, and optimization. The test results showed that the application of this Filtering method proved to be very effective in preventing DHCP Starvation attacks, and the router board resources were not significantly affected when this Filtering method was applied.
