Full text linkIn the current era of modernization, various technological advances that continue to develop make it easier for humans in various fields of life, be it in the fields of Economics, Social, Government or Education which are inseparable from the need for Technology. Istiqomah Mosque is a magnificent house of worship that is an icon of Bengkalis Island. In terms of following technological developments, based on information obtained from the mosque, this mosque still does not have a definite information facility which is one form of the information development process. In terms of disseminating information, this mosque has a social media account, namely Instagram, but it does not play a very important role in disseminating information because it is less efficient so that information related to the mosque is rarely shared through this account. This mosque still disseminates information to the general public manually, namely still using limited media such as the mosque dashboard so that the information obtained by the public is less accurate and also has a less wide reach. Based on this, it can be concluded that this final project research aims to build a website-based application that can provide information on the activities and activities of the Istiqomah Mosque in Bengkalis Regency. The design and creation of this application uses the Laravel framework, PHP programming language, and MySQL database. And from the results of the tests carried out, the test results show that the application can help mosque management officers in managing mosques in managing information data, news and mosque donations
Rancang Bangun Pencetak Briket Otomatis Berbasis Arduino Nano V.30
Full text linkCharcoal briquettes are a solid fuel that contains carbon and has a high calorific value. As a fuel, charcoal briquettes are more profitable than firewood. With the advantage of being a fuel with a higher heat level and being more environmentally friendly than other sources, demand for briquette products from coconut shells in Indonesia continues to increase, especially for cooking purposes. and baking, especially MSMEs which are directly or indirectly related to the briquettes. Working system The working principle of the briquette printing machine with the main source of pressure coming from an electro-pneumatic system, this machine is able to provide pressure in the briquette printing process with pressure variations from 4-10 Bar , the pressurized air originating from the compressor is compressed in the filter regulator and then flows into the water drying filter (filter with condensate drain). Then it flows into the single 5/2 solenoid valve, from the pressure filter regulator which has been cleaned and flows into the single 5/2 solenoid valve and to activate the electro-pneumatic system from the single 5/2 solenoid valve at the power supply slot terminal the voltage flows into the push button, when the push button is pressed the double acting cylinder will move forward and when released the double acting cylinder will reverse and the switch is on/off, and then pressurized air is transferred into the double acting cylinder, this double acting cylinder functions to provide pressure on the briquette printing shaft.
The printing settings are set in a delay which is programmed via the Arduino nano V.30. The design results produce 1 briquette with the printing time of ±30 s. The voltage measurement on the solenoid coil experiences a decrease in voltage due to power losses. Designing must use strong calculations so that the design tools created are optimal. There is a need for additional monitoring in the tool printing process and it can be controlled via applications such as blynk. Perform calculations on wind pressure in accordance with design tools
Analisis Keamanan Login Website Dari Serangan SQL Injection Menggunakan Teknik Filtering
Full text linkIn the current digital era, information security is crucial and takes top priority in website development. The most common security threat to websites is SQL Injection, where hackers or attackers manipulate SQL statements in the login form to forcibly breach or gain unauthorized access. The method employed involves implementing Filtering Techniques in the login form to filter and validate user inputs. This technique aims to prevent special characters that can be exploited by hackers or malicious individuals for SQL Injection. Test results indicate a significant difference before and after applying Filtering Techniques. Prior to implementing filtering techniques in the login form, there was a vulnerability gap in the financial recording website's login form, allowing successful entry into the system during SQL Injection attacks. After applying the combined 3 filtering techniques in the login form namely Input Validation, Escape, and Prepared Statements followed by retesting with 10 bypass attempts, the use of Filtering Techniques proved effective in minimizing SQL Injection attacks on the website's login form
Implementasi Port Knocking Pada Laboratorium Jurusan Teknik Informatika (Studi Kasus: Laboratorium High Performance Computing)
Full text linkObserved several problems in managing the proxy network in the High Performance Computing (HPC) Laboratory at Politeknik Negeri Bengkalis. There is no priority division for users, for example, there is no bandwidth division between lecturers and students, and the main problem is the lack of optimisation of proxy network security. Therefore, the right solution for the HPC Laboratory is to adjust priorities and bandwidth distribution according to user needs and also create a proxy login page to authenticate and user information. The main focus is the implementation of solutions to improve proxy and web server security using the port knocking method and raw firewall security. Implementation of port knocking with various rules including capturing traffic using the ICMP (Internet Control Message Protocol) protocol or pinging that enters the proxy router, then do the same to capture traffic on the Telnet and SSH (Secure shell) ports with the TCP (Transmission Control Protocol) protocol with the purpose of implementing port knocking is to hide active services from attackers and provide an additional layer of verification before providing access to the desired service and as mitigation of DDOS attacks. Tests that will be carried out involve evaluation before and after the application of Port knocking on proxy with Port Scanning testing using NMAP on Kali Linux. The next test on web server security is DVWA (Damn Vulnerable Web Application) using a raw firewall by testing SYN flood and HTTP flood attacks using LOIC. The test results can show a significant decrease in unauthorised access attempts and also get overall network improvement results
