Muhammad Agy Nurwicaksono, Irma Noor Lisa, Astia Rahma Tiara, Rangga Sidik — Wed, 08 Nov 2023 00:00:00 +0700

This study aims to test the legal consulting information system "Advogo" in the hope of finding deficiencies in the system that has been built, and opening up opportunities for improvement and further development of the system. Testing is done by 2 methods, white-box, and black-box testing. The white-box method used in this study is branch and basis path testing, while the black-box method used is the cause-effect graph. The limitation of white-box testing in this study is the SessionController.php file with Index, Create, Store, Show, and Update functions. While the limitations of the black-box are the creation of consultation sessions, authentication, and session bookings. The results of this study are the formation of 10 test cases for white-box testing with 100% valid results, and 14 test cases for black-box testing with 92% valid results, where there is 1 invalid test case so it is necessary to make improvements so that the system can function according to which are expected.

Hanhan Hanafiah Solihin — Sat, 16 Dec 2023 10:20:37 +0700

System automation is currently very much needed for the small and medium business industry to large-scale companies. The computerized systems concept is increasingly in demand due to the shift in the industrial era 4.0. Enterprise Resource Planning (ERP) is a multi-module application that puts forward the concept of an integrated computerized system that stores all company data in one easily accessed database. This study discusses open source ERP applications for Micro, Small, and Medium Enterprises by looking at the running business processes that will then adjust to the ERP application module facilitated by the developer. The Enterprise Architecture Planning method acts as an analysis stage and a tool used in business process analysis using the Unified Modeling Language to identify all actors involved and a matrix of relationships between data entities, business processes, and applications. This research provides recommendations modules that can use in open source ERP applications appropriate for the company.

Practical Work Activities carried out in the Information Systems Study Program at the Faculty of Science and Technology State Islamic University of North Sumatra still carry out the semi-manual attendance recording process. This process is done semi-manually using paper and then entered into Microsoft Excel. This makes the process of processing student attendance data considered less effective and efficient. This is due to the fact that it is difficult to send student attendance data to those who need it and that the data is only stored on a particular computer device. The purpose of this research is to create an android-based application that can be used by the Information Systems study program to process student attendance data and facilitate the distribution of attendance data. This research uses waterfall approach for system development. Includes the stages of Communication, Planning, Modeling, Construction, and Deployment. On the other hand, the system testing method uses the black box testing method. This application is created with a codular framework and spreadsheet database, and can be accessed through android devices and accessed online. The result of this research is in the form of an application that can conduct student practical work attendance and provide report recaps to the study program. This application helps information system study program operators process student attendance data by adding data and facilitating the distribution of attendance data.

Jesica Emarapenta Br Sinulingga, Hizkya Cesar Kayika Sitorus — Sat, 03 Feb 2024 08:29:05 +0700

In the digital era, public opinions regarding Indonesian horror films often receive significant attention on social media platforms. The objective of this study is to assess the perspectives and sentiments expressed by the public concerning Indonesian horror films. The Support Vector Machine (SVM) method along with Term Frequency-Inverse Document Frequency (TF-IDF) is utilized as the primary analytical tool in this research. Issues and public viewpoints regarding horror films are extracted from social media platforms to identify both pros and cons. Employing the SVM method in conjunction with text representation using TF-IDF is expected to provide comprehensive insights into the emotional responses of the public toward specific film genres. The analyzed dataset comprises 2281 entries. Subsequently, the application of the Support Vector Machine (SVM) algorithm is employed for text classification, coupled with word weighting using TF-IDF. The outcomes of this analysis exhibit an accuracy of 82.51%, a precision of 5.28%, a recall of 7.26%, and an F1 Score of 6.12%. This study demonstrates the efficacy of the SVM and TF-IDF methods in classifying public sentiment toward Indonesian horror films and has the potential to provide insights into the social impact and reception of film works within the entertainment industry.

SMA Negeri 1 Bukittinggi is one of the educational institutions in Indonesia. At SMA Negeri 1 Bukittinggi there is an issue that learning activities are carried out using textbooks and PowerPoint slides as the main teaching tools. It was concluded from the results of interviews between researchers and several teachers at SMA Negeri 1 Bukittingi that the average learning media still uses conventional media. This is less effective in its application, especially in chemistry lessons which require special media that are more realistic, such as pictures of molecules and are easily visible inside and outside the classroom. Regarding this problem, research was carried out with the aim of designing Augmented Reality (AR) based chemistry learning media at SMA Negeri 1 Bukittinggi. Researchers use the Unity application as a media design tool. The aim of this research is to design Augmented Reality learning media using Unity at SMA N 1 Bukittinggi that is valid, practical and effective. Researchers use the Hannafin and Peck model as one of the development models for the SDLC method in this research. In the final stage, researchers used validity, practicality and effectiveness tests to draw conclusions about this research. The results of the effectiveness test from 34 students of class 4 validators got an average score of 0.85 (valid). This value test proves that the learning media that has been designed is useful and can be used in learning.

Prediksi Kelulusan Tepat Waktu Siswa SMK Teknik Komputer Menggunakan Algoritma Random Forest

Arina Fatunnisa, Hendra Marcos — Fri, 05 Apr 2024 15:52:13 +0700

School performance can be measured through student completion rates, which is a key indicator. Low graduation rates indicate problems in the education and learning system, which require timely intervention to prevent students from not completing their education. Therefore, predicting graduation rates is crucial for schools in order to determine students who are likely to not complete their education, so as to provide early assistance to improve their academic performance. This research is urgent because by understanding and predicting student completion, schools can allocate resources more effectively to support at-risk students, with the ultimate goal of improving graduation rates and overall school performance. This research uses random forest algorithm with graduation dataset. The distribution of training and test data selection uses stratified random sampling method to ensure a balanced representation of each class generated. The Random Forest model was successfully obtained through training and model evaluation using test data, showing an accuracy of 1.0 or equivalent to 100%. The use of the random forest algorithm on student graduation datasets can be an effective approach in supporting timely graduation prediction due to its high accuracy and the model's ability to recognize both graduating and non-passing students.
