Analysis of Agricultural Commodity Potential in Braja Yekti Village Using the Location Quotient (LQ) Method Based on Geographic Information System (GIS)

2026-07-11T04:32:30+00:00

Braja Yekti Village, East Lampung Regency, has diverse agricultural commodities, yet village development planning has not been supported by evidence identifying commodities with comparative advantages or by spatial information showing their distribution across hamlets. This study aimed to identify leading agricultural commodities using the Location Quotient (LQ) method and to visualize their spatial distribution through a Geographic Information System (GIS). A quantitative descriptive, cross-sectional spatial approach was employed using 2024 harvested-area data for nine agricultural commodities across five hamlets. Secondary data were obtained from the village agricultural extension office and the East Lampung Regency Central Bureau of Statistics, while primary data were collected through field observations and semi-structured interviews with five farmer group leaders. Harvested-area data were analyzed using the LQ method and visualized in QGIS. The findings indicate that seven commodities corn, cassava, peanut, chili, long bean, rambutan, and coconut obtained average LQ values above one, whereas paddy and banana were classified as non-base commodities. Cassava recorded the highest average LQ value (2.78), with strong spatial concentration in Dusun III and Dusun IV. However, several commodities showed LQ values close to the classification threshold and varied among hamlets, requiring careful interpretation. The integration of LQ and GIS provides a spatially explicit evidence base to support village governments in prioritizing commodity-specific agricultural development and location-based planning.

Design And Implementation Of A Web-Based Electronic Correspondence (E-Letter) Information System At The Regional Finance And Asset Agency of East Lampung Regency

The management of incoming and outgoing official correspondence at the Regional Finance and Asset Agency (BPKAD) of East Lampung Regency is still carried out conventionally, in which letters are recorded manually in a logbook, physically distributed between divisions, and archived in paper-based filing cabinets. This practice has led to delays in letter disposition, frequent loss or misplacement of physical documents, difficulty in tracking letter status, and inefficiency in the archiving and retrieval process. This study aims to design and implement a web-based electronic correspondence information system to digitize the administration of incoming and outgoing letters at BPKAD East Lampung Regency. The system was developed using the Software Development Life Cycle (SDLC) with the Waterfall model, consisting of requirements analysis, system design using Unified Modeling Language (UML), implementation using the PHP programming language with the Laravel framework and a MySQL database, and testing using the Black Box Testing method. The results show that the developed system is able to digitize the letter disposition workflow, provide real-time tracking of letter status, generate an automatic letter numbering mechanism, and produce a centralized digital archive that can be accessed based on user authorization levels. Black Box Testing on 15 functional features showed a 100% valid result, while a System Usability Scale (SUS) evaluation involving 20 respondents yielded an average score of 81.4, which is categorized as "Excellent" in terms of usability. The system reduced the average letter disposition time from approximately 1–2 days under the manual process to less than 10 minutes. It is concluded that the web-based electronic correspondence system significantly improves the efficiency, accountability, and transparency of administrative correspondence management at BPKAD East Lampung Regency, with future development directions including integration with a digital signature mechanism and a mobile-based notification system.

Design And Development Of An Early Childhood Development Monitoring And Reporting Information System Using The Web Development Life Cycle (WDLC)Method At Paud Kb Kenanga

Continuous monitoring of early childhood development is essential to ensure that children's cognitive, motor, language, social, religious, emotional, and artistic development progresses according to established developmental milestones. However, the monitoring and reporting process at PAUD KB Kenanga, Raman Fajar Village, is still conducted manually using conventional notebooks, resulting in inefficient data management, difficulties in retrieving historical records, delayed information delivery, and limited parental access to children's developmental progress. Therefore, this study aims to design, develop, and evaluate a web-based Early Childhood Development Monitoring and Reporting Information System using the Web Development Life Cycle (WDLC) method. The study employed the WDLC approach consisting of planning, analysis, design and development, testing, implementation, and maintenance. Data were collected through observation, interviews, and documentation, while system functionality was evaluated using Black Box Testing involving Administrator, Teacher, and Parent access levels. The results demonstrate that the developed system effectively supports administrators in managing developmental data, enables teachers to record and report children's developmental progress digitally, and allows parents to monitor their children's development in real time through an online portal. All 32 Black Box Testing scenarios produced valid results (100%), indicating that the system functions as expected. The implementation of the proposed system improves the effectiveness, accuracy, continuity, and accessibility of developmental monitoring while strengthening communication between PAUD KB Kenanga and parents through an integrated web-based platform.
