Abstract

Academic data management that is not designed with a good database structure often results in data duplication, inconsistency, and difficulties in system maintenance. This study aims to apply the concept of functions, specifically functional dependencies, in designing a simple database for an academic information system that includes data on students, lecturers, courses, study plan cards (KRS), and grades. The research method used is descriptive, with the stages of needs analysis, Entity Relationship Diagram (ERD) design, functional dependency analysis between attributes, normalization to third normal form (3NF), and implementation and testing in MySQL. The results show that the application of the function concept successfully identified six main functional dependencies that form the basis for the formation of five normalized tables: Students, Lecturers, Courses, KRS, and Grades. Query testing on the resulting database showed no data redundancy and all insertion, update, and deletion anomalies were avoided. This study concludes that the function concept is an important foundation in designing an efficient and consistent relational database in small to medium-scale academic information systems.

Abstract

ABSTRAK Tujuan penelitian ini 1). Untuk mengetahui saluran pemasaran mana yang paling efisien dan memberikan keuntungan terbesar bagi produsen kerupuk ikan belidak. 2). Faktor-faktor apa saja yang mempengaruhi besarnya marjin pemasaran kerupuk ikan belidak. Lokasi penelitian ditentukan secara sengaja (purposive) di Desa Piasak Kecamatan Selimbau Kabupaten Kapuas Hulu. Hasil penelitian menunjukkan, saluran pemasaran yang paling efisien adalah saluran pemasaran I ( produsen "“pedagang pengecer "“ konsumen akhir ), dimana saluran ini memberikan harga yang paling besar bagi produsen dengan persentase Farmer"™s Share sebesar 85,71% dan marjin pemasaran yang terkecil 14,28%. keuntungan terbesar terdapat pada saluran pemasaran II Rp.27.418,74/Kg/bln. Faktor-faktor yang mempengaruhi besarnya marjin pemasaran kerupuk ikan belidak di Desa Piasak adalah volume penjualan, harga ditingkat produsen dan jumlah lembaga pemasaran yang dilalui. Kata Kunci : Efisiensi Pemasaran, Kerupuk Ikan Belidak, Margin Pemasaran, Farmer"™s Share, Profitability Indeks.

Abstract

Indonesia, as an agrarian country, heavily relies on the plantation sector as a key driver of its national economy. One significant region contributing to this sector is West Aceh Regency, which consists of 12 districts and is renowned for cultivating five main plantation commodities: oil palm, coconut, rubber, coffee, and cocoa. This research aims to develop a plantation crop production prediction system to support efficient resource planning and management in this sector. The system employs Linear Regression and Single Exponential Smoothing (SES) with a smoothing constant (alpha) of 0.2. The system's primary objective is to analyze historical production data at the district level and generate reliable predictions of future production trends. Linear Regression models the relationship between time (independent variable) and production volume (dependent variable), effectively capturing long-term trends. SES complements this by addressing short-term fluctuations, applying a weighted average where recent data carries greater importance. Prediction accuracy is evaluated using the Mean Absolute Percentage Error (MAPE). Findings reveal that Linear Regression consistently achieves high accuracy, with MAPE values below 20% in most districts, particularly for coffee and cocoa. Conversely, SES demonstrates varying results, performing well in some cases, such as coconut production in Arongan Lambalek (MAPE 20%), but poorly in others, such as oil palm in Bubon (MAPE = 91.06%). In comparison, Linear Regression in Bubon yields a more moderate MAPE of 35.16%. The system is integrated into a user-friendly, web-based platform, accessible to stakeholders like farmers, policymakers, and government agencies. By offering actionable insights into production trends, it aids in mitigating risks, optimizing resource allocation, and enhancing plantation management efficiency. This research underscores the importance of predictive analytics in agricultural planning, with potential applications in other agrarian regions.
