Abstract

This study aims to analyze the influence of Instagram social media marketing and consumer behavior on the purchase decision of orchid ornamental plants (Phalaenopsis) at Yusra Florist Medan Flower Shop. The research method used is a descriptive qualitative approach with a type of field research. Primary data was collected through observation, documentation, and in-depth interviews with six selected informants using purposive sampling techniques, consisting of store owners, sales staff, and customers. Data analysis applies the Miles and Huberman interactive model which includes data reduction, data presentation, and conclusion drawn. The results of the study show that marketing through the Instagram account @yusraflorist_medan.orchid is very effective in expanding the market reach and triggering consumer visual interest through regular product photo and video uploads. Meanwhile, consumer behavior is dominated by the middle and upper class of people who prioritize plant quality, aesthetic value, prestige, and service satisfaction over price sensitivity. The main obstacle found was the limited admin response (slow response) due to dual tasks. In conclusion, the synergy between attractive product visualizations on Instagram and the consistency of direct and digital service quality has proven to be crucial factors that shape customer trust and determine repurchase decisions at Yusra Florist Stores.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh brand image dan community terhadap keputusan pembelian konsumen kosmetik di Medan. Penelitian ini menggunakan metodologi penelitian deskriptif kuantitatif dengan jumlah populasi sebanyak 80 orang. Teknik pengambilan sampel yang digunakan dalam penelitian ini adalah purposive sampling, yaitu minimal 30 sampel. Teknik pengumpulan data yang menggunakan kuesioner sebagai alat ukur juga harus dievaluasi validitas dan reliabilitasnya. Kemudian dilakukan uji asumsi klasik yaitu analisis normalitas, multilinearitas, heteroskedastisitas, autokorelasi, dan regresi linier berganda (RBL). Setelah itu dilakukan uji hipotesis yaitu uji parsial (uji t). Pengumpulan data dilakukan dengan menggunakan SPSS versi 25. Berdasarkan hasil analisis penelitian ini, persepsi konsumen terhadap kosmetik Emina di Medan dipengaruhi secara signifikan oleh Brand Community dan Brand Image. Selain itu, Brand Community dan Brand Image secara simultan berpengaruh signifikan terhadap permintaan konsumen terhadap kosmetik Emina di Medan.

Abstract

ABSTRACT The increasing demand for professional competencies in accounting requires Audit learning to integrate theoretical knowledge with workplace competencies. This study aimed to develop and validate screencast-based learning materials integrated with Level 6 Indonesian National Work Competency Standards (SKKNI) for Accounting Technicians, specifically competency unit M.692000.024.02. The study employed a Research and Development (R&D) method using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation. The participants were 63 seventh-semester Accounting Education students at Universitas Negeri Medan. Data were collected through expert validation questionnaires, lecturer assessments, and student responses and analyzed using descriptive quantitative analysis. This study focused on product development and validation; therefore, comprehensive practicality and effectiveness testing was not conducted. Lecturer assessments and student responses were used as initial information regarding product usability, while effectiveness testing requires broader implementation using a quasi-experimental design to measure improvements in students’ competencies. The results showed that the learning materials obtained a validation score of 4.51 out of 5.00, categorized as highly valid, with a high level of alignment with the targeted SKKNI competency unit. The validation results also indicated the technical feasibility and contextual relevance of the media in connecting academic concepts with auditing practices. Thus, the SKKNI-integrated screencast-based learning materials are considered valid and suitable as supporting materials for competency-based Audit learning. Future research should conduct comprehensive practicality and effectiveness testing through broader implementation and a quasi-experimental design, as well as integrate the materials into a Learning Management System (LMS). ABSTRAK Perkembangan kebutuhan kompetensi profesional di bidang akuntansi menuntut pembelajaran Audit yang mengintegrasikan teori dengan kompetensi dunia kerja. Penelitian ini bertujuan mengembangkan dan memvalidasi perangkat pembelajaran berbasis screencast yang terintegrasi dengan SKKNI Level 6 Teknisi Akuntansi Ahli pada unit kompetensi M.692000.024.02. Penelitian menggunakan metode Research and Development (R&D) dengan model ADDIE yang meliputi tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian terdiri atas 63 mahasiswa Pendidikan Akuntansi semester tujuh Universitas Negeri Medan. Data dikumpulkan melalui angket validasi ahli, penilaian dosen, dan respons mahasiswa, kemudian dianalisis secara deskriptif kuantitatif. Penelitian ini difokuskan pada pengembangan dan validasi produk, sehingga uji kepraktisan dan efektivitas secara komprehensif belum dilakukan. Penilaian dosen dan respons mahasiswa digunakan sebagai informasi awal mengenai keterpakaian produk, sedangkan uji efektivitas memerlukan implementasi lebih luas dengan desain kuasi eksperimen untuk mengukur peningkatan kompetensi mahasiswa. Hasil penelitian menunjukkan bahwa perangkat pembelajaran memperoleh skor validasi sebesar 4,51 dari 5,00 dengan kategori sangat valid dan memiliki kesesuaian yang tinggi terhadap unit kompetensi SKKNI yang ditargetkan. Hasil validasi juga menunjukkan kelayakan teknis dan relevansi kontekstual media dalam menghubungkan konsep akademik dengan praktik audit. Dengan demikian, perangkat pembelajaran berbasis screencast terintegrasi SKKNI dinyatakan valid dan layak digunakan sebagai pendukung pembelajaran Audit berbasis kompetensi. Penelitian selanjutnya perlu melakukan uji kepraktisan dan efektivitas melalui implementasi yang lebih luas dan desain kuasi eksperimen serta mengintegrasikannya dengan Learning Management System (LMS).

Abstract

Production disruptions remain a major challenge in the manufacturing industry, including at Indonesia's largest bread company, PT. Nippon Indosari Corpindo Tbk., which relies on a large-scale automated production system. Despite using modern technology and integrated management systems, the factory often faces technical obstacles that impact production efficiency and continuity. This study aims to analyze the factors that hinder the production process and evaluate the effectiveness of the preventive maintenance system at the Medan Factory of PT. Nippon Indosari Corpindo Tbk. This study uses a qualitative method with a case study approach through interviews, observations, and documentation of employees who are competent in the fields of production and maintenance. The results of the study show that the main obstacles stem from technical factors related to machinery, while human error and delays in raw materials are relatively minimal due to an automated work system and efficient raw material management. High dependence on machinery means that any damage has a direct impact on production continuity. The maintenance system implemented by the company consists of two layers, namely periodic preventive maintenance by technicians from Japan and corrective maintenance by company technicians who are on standby. Although effective in preventing major damage, disruptions still occur between maintenance periods, indicating the need to increase the frequency of maintenance, implement real-time machine condition monitoring, and integrate predictive maintenance to continuously improve production reliability and efficiency.
