Abstract

Identifying functional requirements is a crucial stage in information system development because it determines the suitability of the system to user needs. Errors at this stage can cause the entire system to fail. This study aims to analyze the role of Data Flow Diagrams (DFDs) in identifying the functional requirements of information systems in a systematic and structured manner. The research method used is a descriptive qualitative method with a literature study and system model analysis approach. Data was collected through a review of system design documents and process modeling using DFD, including context diagrams, level 0 DFD, and advanced level DFD. The results show that DFDs are capable of clearly depicting data flows, processes, and interactions between entities, thereby facilitating system analysts in identifying the main functions of the system and user requirements. Thus, the use of DFDs plays an important role in minimizing errors in requirements analysis and improving the quality of information system design.

Abstract

Penelitian ini bertujuan menganalisis dampak pemanfaatan sistem informasi marketplace Shopee terhadap performa penjualan digital Mukhlis Teknik selama 22 bulan (Juni 2024–Maret 2026). Latar belakang penelitian berakar pada fenomena transformasi digital UMKM sektor alat teknik yang dipicu oleh pandemi COVID-19, sebuah sektor yang selama ini kurang mendapat perhatian dalam literatur ilmiah dibandingkan sektor fashion dan FMCG. Metode yang digunakan adalah kuantitatif deskriptif dengan triangulasi data kualitatif yang bersumber dari data transaksional seller center Shopee, observasi lapangan, dan wawancara mendalam dengan pemilik toko menggunakan panduan 18 pertanyaan terstruktur. Hasil penelitian menunjukkan total akumulasi penjualan sebesar Rp4,24 miliar dengan ekspansi pasar dari skala regional Jabotabek menjadi nasional. Performa penjualan membentuk tiga fase berulang yaitu stabilisasi, puncak, dan koreksi yang konsisten dengan pola volatilitas e-commerce global. Tingkat konversi rata-rata 2,64% terbukti lebih ditentukan oleh kualitas traffic dan reputasi toko dibandingkan volume kunjungan, dengan konversi tertinggi 4,66% terjadi justru saat pengunjung paling rendah pada Januari 2025. Rating toko yang stabil pada angka 4,8/5,0 selama seluruh periode terbukti menjadi aset reputasi digital jangka panjang yang menopang stabilitas penjualan di tengah tekanan persaingan harga produk impor. Distribusi produk unggulan menunjukkan dua segmen saling melengkapi antara produk bernilai transaksi tinggi dan produk berfrekuensi tinggi yang bersama-sama memperkuat ketahanan pendapatan bulanan. Penelitian ini menegaskan bahwa UMKM perlu mengintegrasikan manajemen reputasi digital dan diversifikasi produk adaptif sebagai strategi mitigasi risiko persaingan harga di ekosistem marketplace.

Abstract

This study aims to analyze the influence of shipping cost efficiency and freight forwarder quality on export delivery performance at PT Sinar Sawit Sentosa, a palm oil exporting company facing challenges related to rising logistics costs and increasing demands for delivery timeliness. The research problem focuses on the extent to which shipping cost efficiency and the quality of freight forwarder services can improve export delivery performance in a measurable and sustainable manner. A quantitative approach was applied by collecting survey data from the company’s logistics managers and export managers to capture perceptions and experiences related to the research variables. Data analysis was conducted using structural equation modeling to examine the causal relationships among shipping cost efficiency, freight forwarder quality, and export delivery performance. The results indicate that shipping cost efficiency has a positive and significant effect on export delivery performance through reduced operational costs, improved logistics coordination, and smoother export processes. Freight forwarder quality is also proven to have a positive and significant effect through enhanced service reliability, documentation accuracy, and delivery timeliness. The conclusion confirms that the combination of cost efficiency and logistics service quality constitutes a strategic factor determining the success of corporate export delivery. The novelty of this study lies in integrating the measurement of cost efficiency and freight forwarder quality using a SEM approach applied to the Indonesian palm oil export industry, a context that has received limited empirical attention. This contribution provides empirical evidence for the development of export logistics management and strategic decision-making, enriches the academic logistics literature, and offers practical implications for improving national export competitiveness, formulating corporate policies, and managing long-term logistics partnerships based on measurable performance and efficiency orientation. The findings are expected to serve as a reference for future research and professional practice in agribusiness sectors oriented toward global markets with high logistics risks and intense competition that demand continuous, data-driven managerial innovation grounded in reliable and context-specific empirical evidence for the future of national industries.
