A web application is a very important requirement in the information and digitalization era. With the increasing use of the internet and the growing number of web applications, every web application requires an adequate security level to store information safely and avoid cyber attacks. Web applications go through rapid development phases with short turnaround times, challenging to eliminate vulnerabilities. The vulnerability on the web application can be analyzed using the penetration testing method. This research uses penetration testing with the black-box method to test web application security based on the list of most attacks on the Open Web Application Security Project (OWASP), namely SQL Injection. SQL injection allows attackers to obtain unrestricted access to the databases and potentially collecting sensitive information from databases. This research randomly tested several websites such as government, schools, and other commercial websites with several techniques of SQL injection attack. Testing was carried out on ten websites randomly by looking for gaps to test security using the SQL injection attack. The results of testing conducted 80% of the websites tested have a weakness against SQL injection attacks. Based on this research, SQL injection is still the most prevalent threat for web applications. Further research can explain detailed information about SQL injection with specific techniques and how to prevent this attack.

The development of information technology is a new challenge for computer network security systems and the information contained in it, the level of awareness of the importance of network security systems is still very low. according to a survey conducted by Symantec, the desire to renew an existing security system within a year within a company has the result that only 13% of respondents consider changes to the security system to be important from a total of 3,300 companies worldwide as respondents. This lack of awareness results in the emergence of security holes that can be used by crackers to enter and disrupt the stability of the system. Every year cyber attacks increase significantly, so that every year there is a need to improve the security of the existing system. Based on that, a method is needed to periodically assess system and network security by using penetrarion testing methods to obtain any vulnerabilities that exist on the network and on a system so as to increase security and minimize theft or loss of important data. Testing is carried out by using internal network penetration testing method which tests using 5 types of attacks. From the results of the tests, each system has a security risk of 20-80%. From the results of these tests it can be concluded that each system has a security vulnerability that can be attacked.

Patients with arrhythmia symptoms must undergo a healthy lifestyle and routinely conduct consultations and heart rate control with the doctor. The most important thing about this is the integrated health monitoring tool. In this study a portable heart rate monitoring tool is proposed for patients at risk of low-cost IoT-based with SMS alert system utilizing the OpenSID database. . Module ESP8266 Wi-Fi is used to communicate the web server gateway and pulse sensor to detect the heart rate which converted to Bit per Minute (BPM). Heart rate data is saved to the database server using TCP IP communications. Patients and doctors can see heart rate information trough the website in real-time. Alert system will send notification information via short message service (SMS ) to doctors, person in charge and family if heart rate below 60 BPM and above 100 BPM. the time needed for sending SMS is about 7 to 8 seconds. Test results show the whole system is running well. This tool is expected can accompany the risk patients do their activities safely and both doctors and families easier to supervise the patients.

At this time the development of the era is much influenced by technology. This development has an impact on various aspects and fields in the expected life in the field of employment. Al-Azhar 32 Padang Islamic Elementary School is one of the private schools located in the city of Padang, West Sumatra. Al-Azhar schools have staff such as principals, teachers and administration so that the data entered is quite a lot.The staffing system at the Al-Azhar school is still manual by inputting it with excel. To take attendance at the employee using fingerprints and some use the attendance form. However, errors often occur during scanning because the scanner cannot detect someone's finger when the scanner is dirty. So that many employees update attendance by filling out the attendance update form. Given the problems above, it is possible to propose a mobile-based personnel application system. This staffing application has various features that can be used for taking attendance, leave forms, attendance history, school information, and employee profiles. This Android-based attendance can only be taken around the school or less than 20 meters from the school distance. To find out the distance between th0e user and the school, this attendance application uses the haversine algorithm to measure the distance between the user and the school

Since December 2019, the world and Indonesia have fought a major disaster, namely the Covid-19 virus pandemic. With the rapid spread or transmission of the virus, the Indonesian government decided to impose social distancing or social restrictions that impacted the education sector. Students and lecturers cannot conduct lectures face-to-face in class or laboratory, but lectures must be conducted online. For that, we need an open-source system developed by the campus in carrying out online courses. This application was developed using cloud technology and JITSI as an open-source video-conferencing application. In this study, testing of the features that exist in video conferencing and resource usage on the server is carried out. The results of feature testing on the application run as expected with several important features used for learning such as chat, share screen, recording features that can run optimally. The result tested the system resources based on the number of participants, 31 participants with an average use of 2.1GB RAM and 78 participants with an average RAM usage of 2.8GB.

The Indonesian government wants to offer social assistance to lessen the burden on the underprivileged. The DTKS records prospective recipients of assistance as being from low-income families (Social Welfare Integrated Data). The elimination of DTKS will take place in order to stop recipients from receiving social assistance as the recipients' standard of living rises. The standard of living of the recipients and potential beneficiaries will change at some point. Therefore, whether or not the recipients and potential beneficiaries of DTKS are eligible, it is necessary to update the DTKS. The waterfall model SDLC methodology that is being used has the requirement that each process be completed before moving on to the next one or be completed in order. In order to assess the viability of DTKS, the system can use the AHP (Analytical Hierarchy Process) and Borda methods based on the decision maker, criteria, and sub-criteria. Only RT users whose feasibility reference is above 0.29 are considered eligible according to the AHP (Analytical Hierarchy Process) method's feasibility results. The results from the Borda method with the feasibility reference were given the highest priority and the lowest weight, respectively, for the final results on feasibility after going through the AHP process

Di era yang serba canggih dan terbuka ini penggunaan media informasi berbasis teknologi informasi dan komunikasi bagi suatu lembaga sangat diperlukan karena terbukti dapat meningkatkan visibilitas / kehadiran lembaga, menyediakan informasi profil lembaga secara detail, mengkomunikasikan produk dan jasa lembaga, meningkatkan kualitas layanan dan meningkatkan kredibilitas lembaga. Dengan demikian kegiatan pengabdian pada masyarakat (PkM)ini bertujuan untuk menyediakan media informasi dan komunikasi antara rumah tahfizh dengan masyarakat. Mitra dalm PkM ini adalah Rumah Tahfizh Ahlul Quran yang sudah beroperasi cukup lama dan sudah menjalankan berbagai program dan kegiatan, namun masih belum mempunyai media informasi dan komunikasi yang efektif. PkM ini menghasilkan sebuah produk situs web profil dan sosialisasi bagi staf yang mengelola web.
