Optimasi Klasifikasi Risiko Ibu Hamil Menggunakan Support Vector Machine (SVM) Berbasis Particle Swarm Optimization (PSO)

Accurate classification of pregnancy risk is crucial for early detection of complications and reducing maternal and infant mortality rates. However, existing classification models still face challenges in terms of accuracy, particularly in distinguishing between high and very high-risk classes. This study aims to improve the accuracy of pregnancy risk classification models by optimizing Support Vector Machine (SVM) using Particle Swarm Optimization (PSO) algorithm. The study utilizes the "Maternal Health Risk Data" dataset available on Kaggle, which contains information on maternal health. The data is analyzed using two models: standard SVM and SVM optimized with PSO. Evaluation is conducted by comparing the accuracy, precision, recall, and F1-score of both models. The application of SVM without PSO resulted in an accuracy of 77.72%, whereas after optimization with PSO, the accuracy increased to 89.92%. Significant improvements were also observed in precision (from 79.37% to 89.49%) and recall (from 78.81% to 89.55%). The F1-score of the PSO-based SVM model reached 89.52%, demonstrating a good balance between precision and recall.

Rancang Bangun Sistem Penjualan Bunga Di Lembur Kuring Mini Garden

This study aims to develop a desktop-based sales information system to address the limitations of manual data recording at Lembur Kuring Mini Garden, a small business specializing in flower seedlings. Rapid advancements in information technology and the need for accurate, structured, and efficient data processing highlight the importance of computerized systems in supporting business operations. Manual processes such as recording customer data, stock inventory, and sales transactions often lead to errors, data duplication, and delays in decision-making. To overcome these issues, the system was developed using the Software Development Life Cycle (SDLC), which includes planning, analysis, design, implementation, and testing. The application was built using Visual Studio 2012 with C# and SQL Server as the database management system, while Crystal Reports was utilized for generating sales and inventory reports. Data collection was conducted through interviews to obtain system requirements directly from the business owner. The implemented system consists of modules for managing customer data, flower stock, and sales transactions, each equipped with essential functions including add, edit, delete, search, and report generation. Black Box Testing was employed to evaluate system functionality, focusing on input validation, process accuracy, interface responsiveness, and output correctness, all of which showed successful results. The findings indicate that the developed system effectively replaces the previous manual process, improves operational efficiency, reduces recording errors, and provides more organized and reliable information to support decision-making. Overall, the system demonstrates its feasibility and relevance for small businesses that require structured and efficient sales and inventory management.

Pengembangan Agenda & Scheduling Meeting Administration and Reporting Application (ASMARA) Di Kantor BPS Lampung Utara

The inefficiency of manual meeting scheduling at the North Lampung Regency Central Statistics Agency (BPS) has led to frequent data conflicts and communication delays. Conventional calendar applications often fail to accommodate the specific bureaucratic requirement for hierarchical approval before an agenda is publicized. This study aims to develop the Agenda & Scheduling Meeting Administration and Reporting Application (ASMARA) to streamline the scheduling process. The research employs a qualitative applied approach using the Waterfall development method, encompassing requirements analysis, system design, implementation, and testing. The system is built using the Laravel framework and Vue.js, integrated with a Node.js-based WhatsApp Gateway service. The result is a web-based application featuring a role-based approval workflow, where meeting agendas created by staff must be validated by the Head of Office or Sub-division Head. Once approved, the system automatically triggers real-time WhatsApp notifications to all participants. Testing results indicate that ASMARA effectively eliminates scheduling conflicts, ensures administrative accountability through digital approval tracking, and significantly improves information dissemination speed among BPS employees

Derivasi Verba dalam Bahasa Lampung melalui Pendekatan Linguistik Komputasional

This study presents a comprehensive analysis of verbal derivation in Lampung Language Dialects A and O, employing a computational linguistic approach to identify affixation patterns, morphophonemic processes, and the semantic and syntactic contributions of affixes. Verbal data were categorized according to prefixes, infixes, suffixes, and circumfixes. The findings show that both dialects exhibit highly consistent verbal derivation systems. The nasal prefix (N-) is the most productive, marking active transitivity and causativity, with identical nasal assimilation processes in both dialects (b/p → m-, d/t → n-, k/g → ng-, s/c/j → ny-, vowels → nge-/ng-). Other prefixes, such as di-, consistently indicate passivization, while be-/ber- and te-/ti- signal reciprocal/stative verbs and unintentional passives. Major suffixes (-ken, -ko, -an, -kon) function as causative, applicative, or result markers, whereas infixes (-el-, -em-, -en-, -er-) primarily modify phonology or add semantic nuance. Dialect comparison confirms strong structural similarity, with minor phonetic variations, such as object suffixes (-ni/-na in Dialect A vs. -no in Dialect O) and less productive affixes (bu- in Dialect A, per- in Dialect O). Formalization of derivation rules in Python successfully predicted most derived forms, although further refinement is needed for nasal assimilation on vowel-initial stems and vowel deletion in suffixation. This study underscores the fundamental similarity in Lampung verbal morphology and opens opportunities for computational linguistic applications, including morphological analyzers, translation tools, and language learning systems, which are vital for the preservation of regional languages. The results also contribute to a deeper understanding of Austronesian morphological typology.
