Abstract

This study developed a web-based monitoring system integrated into a smart dryer dome for automatic coffee drying. The system utilized the RN-GZWS-RS485 sensor to measure critical drying parameters: temperature, humidity, and light intensity. Data acquisition relied on an ESP32 microcontroller, transmitting real-time measurements to a server using the MQTT protocol, while sensor-actuator interactions operated through the Modbus protocol. Actuator performance adhered to predefined threshold values, maintaining drying temperature within 45–50?°C and relative humidity between 20–40%. Real-time monitoring and system status visualization were implemented via a Laravel-based web interface. Experimental tests demonstrated that 71.76% of temperature readings, 64.71% of humidity readings, and 68.24% of light intensity readings consistently fell within optimal ranges. Low standard deviation values confirmed the system’s effectiveness in maintaining stable drying conditions. Additionally, the integration of solar power facilitated system deployment in remote locations without conventional electricity infrastructure. These findings highlight the system's potential to improve the reliability, accuracy, and efficiency of automatic coffee drying processes.

Abstract

persaingan yang ketat antara perusahaan dalam pelayanan travel yang ada di daerah membutuhkan perbaikanpelayanan kualitas untuk memenuhi target penumpang.Ketidakpuasan pelanggan disebabkan oleh faktor facility, place,product, people, dan competitor. Ketidakpuasan ini menjadisuatu permasalahan yang harus diperbaiki sehingga denganmenerapkan metode ini dapat meningkatkan service quality PT.XYZ. Tugas Akhir ini bertujuan untuk menganalisa kepuasanpelanggan PT. XYZ dengan mempertimbangkan keberadaanpersaingnya yaitu Perusahaan Kompetitor dan memberikanrekomendasi perbaikan terhadap atribut kenyamanan yangmenjadi prioritas perbaikan. Penelitian ini menggunakan metodeImportance Performance Competitor Analysis (IPCA). Pengambilan data dilakukan terhadap dua kelompok respondenyaitu responden PT. XYZ dan responden Perusahaan Kompetitor. Tugas akhir ini mengukur tingkat pelayanankualitas berdasarkan 5 dimensi yaitu Reliability (6 butir atributkebutuhan), Comfort (5 butir atribut kebutuhan), Extent of Service (3 butir atribut kebutuhan), Safety (6 butir atributkebutuhan), Affordability (3 butir atribut kebutuhan).Berdasarkan hasil pengolahan data dengan IPCA didapatkan bahwa terdapat pernyataan yang masuk dalam kuadran UrgentAction dan Head-to-Head Competition yang memerlukanperbaikan yaitu kebersihan toilet di ruang tunggu, ketersediaan kursi di ruang tunggu, kebersihan ruang tunggu, ketepatanwaktu datang kendaraan travel, lokasi shuttle yang strategis, dan beberapa rekomendasi perbaikan atribut lainnya. Kata kunci - Importance Perfomance Competitor Analysis (IPCA), Servqual, Customer need, Customer satisfaction,Transportation service
