Abstract

Memelihara ikan hias di masyarakat sudah menjadi hobi sejak jaman dahulu hingga saat ini. Dalam kegiatan memelihara ikan hias ada beberapa hal yang penting dalam pemeliharaannya yaitu pemberian pakan ikan dan pengontrol terhadap kualitas air seperti kejernihan air karena unsur-unsur tersebut penting bagi pertumbuhan dan kehidupan ikan. Namun masalah muncul saat penghobi tidak berada dirumah dan tidak bisa merawat ikan peliharaan secara langsung terutama memberi makan. Untuk mengatasi masalah tersebut alat pemberian pakan ikan dan pemantauan kondisi air otomatis sangat diperlukan. Pada rangkaian alat pemberi pakan ikan dan pemantauan kondisi air otomatis menggunakan motor servo yang akan menjadi pembuka dan penutup katup pakan ikan, dan Modul GSM yang akan menjadi jembatan ke Arduino sebagai penerima dan pengirim sms, kemudian LCD yang akan menampilkan hasil data kekeruhan air. Program dirancang agar bisa memberi pakan ikan banyak, memberi pakan ikan sedikit, dan khusus mengetahui kondisi air melalui SMS. Berdasarkan penelitian yang telah dilakukan sistem pemberi pakan ikan dan pemantauan kondisi air otomatis via SMS gateway menggunakan Arduino Uno dapat bekerja dengan baik dimana pakan ikan akan akan keluar secara otomatis apabila pengguna mengirimkan pesan via SMS sesuai dengan nomor SIM card yang ada di sistem (Modul GSM).

Abstract

Website security is often ignored by developers, including small websites or company profile websites that have data that may be stolen by irresponsible parties. Self-test is needed in order to find out security holes that might be attacked. Therefore, a vulnerability assessment is needed to find security holes. Vulnerability Assessment (VA) is a system scanning process to find vulnerabilities and loopholes in a website system, this loophole provides a backdoor for attackers to attack the victim's system. Owasp-zap is an application that can look for a security hole in the website system, after information about the vulnerability is obtained, the developer can make changes or add scripts to a system so that security holes can be overcome in order to maintain data integrity from attacks by irresponsible parties.

Abstract

Path search is closely related to distance with searching at a location or place in a mapping in a search many heuristic algorithms are used. One of the algorithms used to determine the closest path is the floyd warshal algorithm which applies a heuristic function so that it will provide the most effective path search results. The problem that arises when the general public wants to find the nearest hospital is that there is no information that can be used as a medium that can determine the nearest hospital, therefore this study will apply the floyd warsahll algorithm with a distance formula that can be used to determine the best path or the closest distance To reach the nearest hospital, one of the distance formulas is the Euclidean Distance formula which is a calculation of the distance from 2 points in the Euclidean Distance space. the overall result of the calculation between the starting point or starting point with the end point or end node in the current case the starting point is at Permata Bunda Hospital which is assumed to be the starting point and ending point, namely the Madani Hospital. The results show that for a civil hospital the closest distance is 0.88 km which passes through nodes 2,3, and 4.
