Abstract

ABSTRACTUD Mitraco Utama is one of the companies in the chemical industry or chemical industry such as perfume,hand sanitizer and others, and the company currently has around 40 employees where employees perform attendance using manual attendance machines and the administration section every month must recap Reset all employee attendance data manually and then calculate employee salaries with Microsoft Excel using a system like this, in a way that is prone to data calculation errors which can also affect the employee salary, where the calculation of the salary becomes longer which can cause delays in processing and receiving employee salaries. And there are also other problems, namely the lack of speed and accuracy in finding employee salary data for a certain period or annual period. Therefore improvements were made by creating an attendance and payroll information system to make it easier to record attendance data, calculate employee salaries through attendance data obtained every working day, and make it easier to find these data. Attendance and payroll information system testing is carried out using the black box testing method to find out that the system has produced the expected output.Keywords: information system, attendance salary, webABSTRAKUD Mitraco Utama merupakan salah satu perusahaan di bidang chemical industry atau industri bahan kimia seperti parfum, hand sanitizer dan lain-lain, dan perusahaan saat ini sudah memiliki sekitar 40 pegawai dimana pegawai melakukan absensi dengan menggunakan mesin absensi manual dan bagian admnisitrasi setiap bulannya harus merekap ulang semua data absensi pegawai secara manual lalu kemudian melakukan perhitungan gaji pegawai dengan Microsoft Excel dengan menggunakan sistem seperti ini, dengan cara seperti rentan akan terjadinya kesalahan perhitungan data yang juga dapat berpengaruh pada gaji karyawan tersebut, dimana perhitungan gaji menjadi lebih lama yang bisa meyebabkan keterlambatan dalam memproses dan penerimaan gaji pegawai. Dan terdapat juga permasalahan lainnya yaitu kurangnya kecepatan dan ketepatan dalam mencari data gaji pegawai dalam periode tertentu atau periode tahunan. Dari permasalahan tersebut memunculkan gagasan untuk membuat sistem informasi absensi dan penggajian agar mempermudah dalam melakukan proses pencatatan data absensi, perhitungan gaji pegawai melalui data absensi yang didapat setiap hari kerja, dan akan mempermudah dalam hal mencari data-data tersebut. Pengujian sistem informasi absensi dan penggajian dilakukan dengan metode black box testing untuk mengetahui sistem telah menghasilkan output yang diharapkan.Kata Kunci: Sistem informasi, absensi penggajian, web

Abstract

Computer networks are essential for modern life, enabling efficient global information exchange. However, as technology advances, network security challenges grow. To enhance security, honeypots are used alongside firewalls, mimicking legitimate systems to attract hackers and analyze their attack methods. In this research, Cowrie and Dionaea honeypots are implemented. Cowrie targets brute force attacks on SSH, while Dionaea detects port scanning and denial of service (DoS) attacks. These honeypots effectively capture and log malicious activities, providing insights into attack patterns. The collected data is analyzed using the ELK Stack, which offers real-time visualization of attack trends, frequency, and methods. This analysis helps security teams quickly identify and mitigate threats. The integration of honeypots with the ELK Stack significantly enhances network defense by improving detection, analysis, and response to cyber threats. The analysis of the results shows that both honeypots effectively capture and record malicious activities entering the network, providing critical insights into the attack patterns employed by attackers. Within just minutes of deployment, the honeypots logged over 1,000 attacks, predominantly originating from botnets attempting to exploit system vulnerabilities. The captured log data is processed through the ELK Stack, allowing for real-time visualization of attack patterns, including geographic origins, attack frequency, and methods used. This enables security teams to proactively identify trends, assess risks, and implement targeted mitigation strategies more efficiently.

Abstract

Many government programs have been created to overcome poverty in an area. However, the assistance provided is not on target so it has not reached the hands of the people who really need it. This happened because the determination of prospective poor families to receive BLT was not optimal. Seeing this, the author helped the Head of Social Welfare by creating a Decision Support System for Determining Poor Families Using the Simple Additive Weighting (SAW) Method. Case Study: Batubulan Village Perbekel Office so that it could provide two categories namely poor and not poor. The SAW method was chosen because it can determine the weight value of each criterion and then continue with the ranking process which will select a number of alternatives, in this case families that are categorized as poor families. With this ranking process, correct assessments and accurate results are obtained both in manual calculations and system calculations.
