Abstract

Penentuan tingkat kematangan buah sawit merupakan salah satu faktor penting dalam menentukan waktu panen yang tepat. Penilaian secara manual masih memiliki keterbatasan karena bergantung pada pengamatan visual dan pengalaman pengguna. Penelitian ini bertujuan untuk merancang dan membangun alat ukur tingkat kematangan buah sawit menggunakan sensor warna berbasis Internet of Things (IoT). Sistem menggunakan mikrokontroler ESP32 dan sensor warna TCS3200 untuk membaca karakteristik warna buah dalam bentuk nilai RGB. Data tersebut kemudian diolah menjadi parameter Hue, Brightness, dan Rasio Merah untuk mengidentifikasi empat tingkat kematangan, yaitu mentah, mengkal, matang, dan lewat matang. Hasil identifikasi ditampilkan melalui LCD 20×4 dan dikirimkan melalui jaringan WiFi ke aplikasi Blynk, sehingga hasil pengukuran dapat dipantau secara real-time melalui smartphone. Berdasarkan pengujian terhadap 10 sampel buah sawit, sistem mampu melakukan klasifikasi dengan tingkat ketepatan sebesar 80%. Pengujian waktu respon menunjukkan rata-rata waktu pembacaan sensor sebesar 5,00 detik, sedangkan waktu data tampil pada Blynk sebesar 2,63 detik. Hasil penelitian menunjukkan bahwa sistem yang dirancang dapat bekerja dengan baik dalam membantu proses identifikasi tingkat kematangan buah sawit secara otomatis serta mendukung pemantauan hasil pengukuran melalui teknologi IoT. Kata Kunci: Buah Sawit, Tingkat Kematangan, TCS3200, ESP32, Internet of Things, Blynk =================================================================================== Purpose – This study aims to analyse the effect of product quality, servicescape, brand image, and price on consumer satisfaction at Lucky Ponsel Store Rantauprapat, both partially and simultaneously, and to identify the most dominant determinant. Design/methodology/approach – A quantitative approach with an explanatory survey design was employed. The sample consisted of 96 respondents determined by the Lemeshow formula, as the population size was unknown, and selected through purposive sampling based on predetermined inclusion criteria. Data were collected using a closed-ended questionnaire of 20 items on a five-point Likert scale and analysed with multiple linear regression in SPSS version 29 after satisfying validity, reliability, and classical assumption tests. Findings – The results show that product quality (β = 0.213; sig. = 0.003), servicescape (β = 0.144; sig. = 0.028), brand image (β = 0.506; sig. < 0.001), and price (β = 0.283; sig. < 0.001) have a positive and significant partial effect on consumer satisfaction, and a significant simultaneous effect (F = 56.292; sig. < 0.001) with an adjusted R Square of 0.700. Brand image is the strongest predictor, whereas servicescape contributes the least. Research limitations – The limitations of this study lie in the use of a single retail outlet as the research site, its cross-sectional design, and its reliance on respondent perceptions, which restricts the generalisability of the findings. Implications – Theoretically, the study extends expectation-disconfirmation theory and the servicescape concept to an electronic-product retail setting; practically, store managers should prioritise strengthening brand image and guaranteeing product authenticity before investing in the physical arrangement of the outlet. Originality – The novelty of this study lies in testing the four determinants simultaneously in a single model within a mobile-phone retail context in a regency town, a setting that remains under-examined in the consumer satisfaction literature. Keywords: Product Quality, Servicescape, Brand Image, Price, Consumer Satisfaction
