Implementation of Artificial Intelligence and Deep Learning for Optimizing Sustainable Agricultural Production

Syaharuddin Syaharuddin — 2026-07-08

This study aims to explore the application of Artificial Intelligence (AI), deep learning technologies, and machine learning approaches for optimizing sustainable agricultural production, particularly in agricultural price forecasting. Using a Systematic Literature Review approach, this research collects and analyzes literature indexed in Scispace, Google Scholar, DOAJ, and Scopus published between 2014 and 2024. The findings indicate that AI, deep learning, Support Vector Machine (SVM), and Relevance Vector Machine (RVM) technologies hold significant potential in improving operational efficiency, food security, and forecasting accuracy in the agricultural sector. These technologies can support various aspects of agriculture, including agricultural price forecasting, crop yield prediction, plant disease detection, and more efficient natural resource management. However, the implementation of these technologies still faces several significant challenges, such as inconsistent data quality, high implementation costs, ethical issues related to data usage, and infrastructure limitations in rural areas. This study concludes that while these technologies offer considerable potential, their successful implementation depends heavily on addressing these challenges and developing policies that support the sustainable adoption of technology in the agricultural sector.

Internship attendance is one of the most important aspects of the administrative process in government agencies. The manual attendance recording process often causes various problems, such as recording errors and delays in data recapitulation. This study aims to design and build a website-based internship attendance information system at the Garut Regency Department of Industry, Trade, Energy, and Mineral Resources (DISPERINDAG ESDM). The system was developed using the CodeIgniter 3 framework with a Model-View-Controller (MVC) architecture and a MySQL database. Data collection methods were carried out through observation, interviews, and documentation, while the system development method used the Prototype method that involved users in the process of evaluating and refining the system. The implementation results showed that the website-based internship attendance system was able to accelerate the attendance recording process, reduce data input errors, and produce more accurate and user-friendly information. Thus, the system developed can improve the effectiveness and efficiency of internship administration management in government agencies.

Chicha Silvi Aulia — 2026-07-08

The use of information technology plays an important role in improving organizational efficiency, particularly in Business Process Outsourcing (BPO) companies that rely on Agent performance. This study aims to design a web-based Agent Evaluation and Training Information System to overcome the limitations of the existing system in quiz management, assessment, and reporting. The study applies the System Development Life Cycle (SDLC) using the Waterfall model and adopts the Object-Oriented Analysis and Design (OOAD) approach with Unified Modeling Language (UML). The proposed design identifies three main actors, namely Admin, Reviewer, and Agent, and includes modules for quiz management, evaluation, and reporting. Compared with the existing system, the proposed design provides campaign- or division-based question bank management, role-based evaluation mechanisms, and integrated reporting. The proposed design is expected to support a more flexible, accurate, and integrated Agent evaluation and training process.

Optimasi Memaksimumkan Keuntungan Produksi Pada Bulu Mata PT. Daux Cosmetic Menggunakan Linear Programming

Muhamad Fahmi Nugraha — 2026-07-08

PT. Daux Cosmetic, an eyelash manufacturer located in Garut, Indonesia, faces challenges in optimizing the production mix of two eyelash models—Model A and Model B—under limited production and quality control time. This study aims to determine the optimal production combination to maximize profit using Linear Programming (LP). Two complementary approaches were employed: the graphical method for feasible-region visualization and the simplex method for iterative algebraic solution. Based on the LP formulation with objective function Z = 10,000,000X? + 4,500,000X? and two capacity constraints, the optimal solution was obtained at point B (X? = 10, X? = 60), allocating 10 hours to Model A and 60 hours to Model B, yielding a maximum profit of IDR 370,000,000. Both methods yielded consistent results, confirming LP as a reliable production-planning tool and a sound basis for operational decision-making.

Deteksi Sistem Cerdas Kerentanan Kode PHP Menggunakan Hybrid ML dan LLM

Moh Erdda Habiby Habiby — 2026-07-08

Security vulnerabilities in PHP programming code remain one of the major threats to the integrity of web applications, especially when software development processes are not supported by automated and adaptive security analysis mechanisms. This study aims to develop an intelligent system for vulnerability detection and automatic code remediation using a Hybrid Machine Learning (ML) and Large Language Model (LLM) approach. The system combines Term Frequency-Inverse Document Frequency (TF-IDF), Abstract Syntax Tree (AST) Parsing, and the Random Forest algorithm for vulnerability classification, while integrating the Google Gemini API as a dynamic recommendation layer to generate contextual and adaptive secure coding suggestions. The dataset consists of 320 PHP code snippets covering SQL Injection, XSS, File Inclusion, Command Injection, Unsafe File Upload, and safe code samples. Experimental evaluation using accuracy, precision, recall, F1-score, and confusion matrix shows that the model achieved an overall accuracy of 86.25% with a macro average F1-score of 0.86. This study demonstrates that integrating Hybrid ML and LLM-based remediation using the Gemini API has strong potential for developing intelligent static code analysis systems for PHP web applications.
