Abstract

VPN adalah sebuah teknologi komunikasi yang menggunakan jaringan private (pribadi) yang dapat terhubung ke sebuah jaringan publik. Dengan cara tersebut, maka akan didapatkan hak dan pengaturan yang sama seperti halnya berada didalam jaringan lokal itu sendiri, walaupun sebenarnya menggunakan jaringan publik. Pada penelitian ini yang dipakai adalah protokol GRE over IPSec. GRE adalah protokol enkapsulasi yang secara default tidak mendukung keamanan enkripsi. Maka untuk menambahkan lapisan enkripsi di GRE Tunnel dengan dukungan IPSec dan protokol enkripsi IKEv2. Maka dibuat lah kombinasi antara GRE dan IPSec pada Fortigate yang memungkinkan pengguna untuk membuat jalur tuneling aman antara dua jaringan yang berbeda. Seluruh lalu lintas data yang melewati jalur tuneling akan dienkripsi menggunakan protokol IPSec. Setelah berhasil membangun VPN tunnel GRE Over IPSec, kemudian jaringan tersebut di uji. Hasil pengujian terhadap GRE Over IPSec tunnel VPN dengan protokol IKEv2 sudah berjalan dengan baik dan paket yang melalui tunnel tersebut sudah terenkripsi dengan aman. Sedangkan Dari hasil pengujian yang telah dilakukan terhadap performa jaringan GRE over IPSec pada Fortigate dilakukan untuk mengukur performa dari delay dan throughput paket yang dikirim, pengujian dilakukan dua kali pengujian yaitu upload dan download. Menurut THIPON dari jaringan yang dibangun termasuk kedalam kategori “sangat bagus”.

Abstract

Teknologi menjadi kebutuhan sehari-hari bagi banyak orang. Penggunaan teknologi yang tidak tepat dapat menimbulkan dampak negatif baik bagi individu maupun organisasi seperti mendapatkan informasi-informasi yang bersifat illegal. Hal ini dapat dilakukan dengan memanfaatkan teknologi komputer sehingga menimbulkan kejahatan siber seperti eksploitasi website dengan serangan cross-site scripting. Untuk mengungkap kasus tersebut dibutuhkan bukti digital untuk membantu dalam mengungkap kasus tindak kejahatan siber seperti disk image yang berisikan file system, file temp (log), dan partisi disk lain didalamnya. Upaya dalam memperoleh dan menganalisis barang bukti digital tersebut dilakukan dengan teknik static forensic dengan menerapkan metode NIST. Teknik static forensic, memperoleh bukti digital dengan melakukan ekstraksi dan analisis setelah terjadi insiden ataupun setelah sistem tidak beroperasi. Penelitian ini menghasilkan artifak-artifak barang bukti digital (evidence) berupa disk image, file access.log yang mencatat seluruh permintaan yang dilakukan pelaku terkait serangan reflected cross-site scripting dan stored cross-site scripting yang tercatat pada log server, dan IP Address pelaku. Sedangkan pada file error.log tidak ada indikasi terjadinya serangan cross-site scripting dan tidak menghasilkan bukti apapun indikasi serangan. Barang bukti tersebut, diolah dan disajikan sebagai laporan hasil investigasi digital forensic untuk memperkuat kasus hukum terhadap pelaku serangan.

Abstract

A private company engaged in heavy equipment rental services, established on June 19, 2012, in Pekanbaru. In the current business process, customers who wish to rent heavy equipment or seek information about it can only do so during office hours, making the rental process less efficient. Record-keeping is still done using Excel, which increases the risk of data loss. Therefore, a solution has been proposed to develop a web-based information system to access and manage the process easily. The information system was developed using the prototyping method. The choice of the prototyping method is made to speed up development time, ease system completion, and avoid discrepancies between developers and users. The information system is then tested through Black Box testing and usability testing. From the Black Box testing results, it was found that the system's functionality for all users has been successfully implemented and operates as expected. Meanwhile, the usability testing results showed an average score of 89%, indicating that users strongly agree with the system's usability. This research helps to facilitate customers and administrators in the heavy equipment rental process by providing quick and easy access to information on prices, schedules, and equipment types, while also improving data recording to reduce the risk of data loss and facilitate administrative tasks.

Abstract

This study aims to develop an educational software platform that supports Indonesian students in learning stock market behavior by addressing low financial literacy, limited analytical skills, and emotion-driven investment decisions. The proposed platform integrates historical data from liquid IDX80 stocks with a Long Short-Term Memory (LSTM) forecasting model enhanced by technical indicators and calendar-based market features, and presents predicted price movements and trend classifications through an interactive, user-friendly learning interface. Experimental results show that the model achieved strong predictive performance on most IDX80 stocks, demonstrating its ability to capture temporal price patterns, while the inclusion of technical and calendar-based features improved prediction clarity and trend interpretability for student users. Variations in forecasting accuracy across stocks indicate that liquidity and volatility influence model performance, highlighting the importance of contextual interpretation in learning. In conclusion, the findings indicate that integrating LSTM-based forecasting with instructional design principles can support experiential and data-driven investment learning, and the developed platform demonstrates strong potential as both a forecasting tool and an educational technology medium for supporting financial literacy development.

Abstract

Learning process between students and teachers includes face-to-face activities and evaluation in the form of exams. In certain conditions, such as the natural disasters of haze or disease outbreaks, the teaching and learning process cannot be done directly. One alternative to face-to-face activities in the teaching and learning process is SPADA (Online Learning System), which was inaugurated nationally in 2014. This online system allows students and teachers to be in different places but can carry out online learning. Apart from online learning, exams or evaluations can also be done online. There are many free applications that can be used to create an online exam system, known as CBT. However, not all teachers understand and know how to use and make the CBT application. In this Community Service activity, lecturers in the Computer Engineering Study Program provide training and workshops on how to use and create CBT applications online through the Zoom Cloud streaming application. The workshop which was held for two days was attended by approximately 225 participants from high school and equivalent teachers who came from various cities in Riau and a small part from outside Riau and outside Sumatra.

Abstract

Currently, the whole world is struggling to deal with the COVID-19 pandemic. During the pandemic, many things were affected and changed the habits of all mankind in the world, including the field of Education which changed drastically. Previously, the teaching and learning process was mostly done face-to-face in the same place or location, but now it has to be done online. During the online learning process, many problems arise from both the teacher and student. One of them is that students get bored quickly, lack of student involvement and participation in the teaching and learning process. This is a challenge for teachers how to create an interesting and interactive learning atmosphere. However, the obstacle faced by teachers is that not all teachers understand and know what media can be used to make the learning process interesting and interactive. Based on these problems, in this Pengabdian kepada Masyarakat activity, training activities for making teaching devices using a Mentimeter have been carried out for teachers of SMK Taruna Persada Dumai which was held on September 25, 2021 with a total of 16 participants. The purpose of this activity is to prepare an interesting and interactive teaching and learning process to increase student involvement and participation when the teaching and learning process is carried out online and to help partners have basic understanding and skills in using interactive learning applications. The result of this activity is an evaluation of activities that have been carried out through a questionnaire, it is found that the material presented can add insight to the teacher, in accordance with the expected competencies so that later it can be applied to the teaching and learning process. In addition, participants felt comfortable following the training because of the positive interaction between participants and presenters and the way the material was presented in an interesting way. Based on the results of the questionnaire, recommendations were also obtained for the next activity in the form of training in making learning videos and using other learning media to support the teaching and learning process.

Abstract

The use of servers that have to run continuously for 24 hours and running services generates a lot of logs. This requires that the system administrator in his checks still have something to do with the server. This research intends to design a Monitoring Log Server using the ELK Stack (Elasticsearch Logstash Kibana) which can make it easier to read and analyze service logs on the server. The implementation in this research uses Ubuntu 18.04 Server, and a client server with SSH Putty service. From the results of the ELK Stack research, a solution in the form of Monitoring Log Server is obtained to make it easier for administrators to check every access log. Based on the results of the first and second scenario testing, the results obtained are successful in displaying data for each log that can be read by the administrator for a period of time based on data per day and per week. For the third scenario the administrator can see the level of accuracy of each access log. And the last scenario is the result to make it easier for administrators to audit or check every access log.
