Abstract

In this study, the Researchers provide the design, development, and evaluation of a web-based SQL exam system that utilizes the Model-View-Controller (MVC) architectural pattern to enhance automated grading functionality and ease of maintenance. The main objectives of the system are to simplify the process of administering SQL exams, to make it user-friendly for students to enter their SQL statements, and as a means for teachers to automate the grading process. This allows a clear separation between three separate modules: Model to manage data, View to present the application to users, and Controller to manage the application logic. This separation allows for modular development, easier maintenance, and code reuse. The fundamental aspect of the system lies in its automated grading mechanism, which intelligently compares the SQL queries submitted by students with the corresponding validated answer keys stored in the database. Extensive black-box testing was conducted to ensure the reliability and accuracy of the system with various test cases to assess its ability to assess responses and provide real-time feedback to students, in addition to smooth and intuitive navigation within the system. All testing criteria yielded successful results with 100% agreement proving the robustness of the system with all possible locations that could potentially be used in higher education structures. The system provides a scalable and flexible approach to address the challenges associated with SQL assessment in academic institutions, thereby facilitating uniform, efficient, and objective evaluation standards. The system uses data up to October 2023 to prevent the model from becoming obsolete

Abstract

Forest and land fire significantly impact the balance of the environment, such as haze pollution, destruction of ecosystems, the high release of carbon in the air, deterioration of health, and losses in various other fields. Based on these factors, developing an early warning system is essential to prevent forest fires, especially in forest and land areas. One of the data that can be used to monitor areas where there are frequent fires is hotspot data taken from the NASA MODIS Fire satellite. Data mining techniques are carried out to process the hotspot data so that the distribution of hotspot swarms is obtained. The data on the distribution of the clustering of hotspots are used to detect areas that are prone to fire from year to year. This study used the K-Means clustering algorithm. The data used in this study is hotspot data from Malang District, Indonesia. The range of hotspot data from January 2018 to June 2022. We use Silhouette coefficient testing to get the best number of classes in the cluster—this study's most recent application of the K-means clustering method to analyze hotspot distribution in a spatial-temporally. We use hotspot data in Malang's forest and land area using hotspot confidence levels >80%.

Abstract

Proses manajemen seperti pencatatan peminjaman, pengembalian, dan inventaris buku yang ada di Perpustakaan SMAN Ploso masih menggunakan proses pencatatan pada buku. Selain itu, proses pengembalian buku belum terorganisir dengan baik, karena masih terdapat anggota perpustakaan yang mengembalikan buku pada rak yang tidak semestinya. Maka dari itu, sistem ini dibuat bertujuan untuk memberikan kemudahan dalam proses pengelolaan data perpustakaan dan memberikan rekomendasi penempatan buku dan pengadaan buku berdasarkan pola peminjaman. Sistem ini memiliki fitur pengelolaan data perpustakaan seperti data buku, anggota, peminjaman, pengembalian, rekomendasi penempatan buku berdasarkan kategori pada data transaksi, rekomendasi pengadaan buku berdasarkan data transaksi, laporan, dan denda. Pada sistem ini admin dapat melakukan perhitungan Algoritma Apriori pada menu penempatan buku dengan memasukkan rentan waktu data peminjaman, nilai minimum support, dan nilai minimum confidence. Berdasarkan pengujian yang dilakukan, admin memasukkan rentan waktu bulan Januari – Februari. Kemudian untuk nilai minimum support sebesar 10% dan nilai minimum confidence sebesar 60%. Berdasarkan analisis yang telah dilakukan, pemilihan nilai minimum support 10% dan nilai minimum confidence 60% memperoleh hasil yang ideal, karena itemset dan aturan asosiasi yang muncul memiliki keterkaitan yang signifikan. Dari nilai-nilai tersebut kemudian diproses oleh sistem dan menghasilkan nilai confidence 4 itemset, di mana masing-masing itemset tersebut memiliki nilai persentase confidence yang telah memenuhi nilai minimum confidence. Dari hasil yang diperoleh kategori kimia dan matematika sebesar 100%, kategori ekonomi dan geografi sebesar 62,5%, kategori geografi dan ekonomi sebesar 83,3%, kategori fisika dan matematika sebesar 80%.

Abstract

Clustering is one of the key techniques in unsupervised learning analysis, aimed at grouping similar data objects into clusters based on shared characteristics. The broad benefits of clustering are evident across various sectors, such as business, marketing, finance, and many others. However, the complexity of implementing clustering, especially for those without a background in statistics or programming, poses a barrier. The appropriate selection of clustering methods and accurate interpretation of results require a solid understanding of statistics. This research aims to address this issue by crafting a detailed Software Requirements Specification for a user-friendly clustering application, equipped with an intuitive interface and effective tools, based on comprehensive literature study, which finally allowing non-experts to engage in the clustering process without in-depth knowledge of statistics or programming. As such, this study endeavors to provide a practical solution for utilizing clustering without excessive technical impediments.

Abstract

Malnutrition, both in the form of overweight and underweight, remains a global health challenge. Unhealthy urban lifestyles and limited access to appropriate nutritional interventions exacerbate this problem. Technology-based approaches such as machine learning and Large Language Models (LLM) offer opportunities to improve the effectiveness of dietary management. This study proposes the development of a machine learning-based and LLM-integrated diet program prediction and recommendation system applied to Cafe NUT Castle. The system was developed to digitize body composition data recording, predict diet programs (weight loss, weight gain, and body fat loss) using the Random Forest algorithm, and generate personalized initial diet recommendations through the integration of the Gemini Flash-Lite API. Based on the test results, the prediction model achieved an accuracy of 93% on the test data and 84% on 50 new datasets. Evaluation of the diet recommendations generated by LLM showed a feasibility level of 86.6% which was categorized as very feasible. These results indicate that the developed system is not only accurate in predicting diet programs but also effective in providing initial recommendations that can support decision-making in digital nutrition consultation services.
