Abstract

This research focuses on analyzing queues at the Teras Coffe cafe using the single channel method. Queues often occur at this cafe due to the high volume of visitors, which causes long waiting times for customers. The aim of this research is to optimize customer waiting time by understanding the existing queuing system. The method used in this research includes collecting primary data through interviews and direct observation in the field. The data obtained includes the time of customer arrival and the duration of service provided by the cashier. By using the single channel method, where there is only one service channel, this research aims to provide a clear picture of the expected waiting time and the number of customers waiting in the queue. The analysis results show that with better arrangements in the service system, waiting times can be minimized. It is hoped that this research can provide useful recommendations for cafe managers in improving service efficiency and customer satisfaction. Thus, this research not only provides insight into queue management, but also contributes to a better customer experience at the Teras Coffe cafe.

Abstract

Telah dilakukan penelitian material komposit dalam bentuk penyimpanan unsur kimia berupa nutrisi/pupuk dalam bidang agricultural. Komposit ramah lingkungan, murah serta mudah didapat ini dibuat dari campuran alginat dan zeolit. Komposit disintesis dengan komposisi alginat/zeolit (1:1) dan variasi kation Fe, Zn dan Fe-Zn. Penelitian ditujukan untuk mengetahui karakter komposit alginat/zeolit yang terembankan kation Fe dan Zn didalamnya, karakterisasi dilakukan baik secara visual fisik dan molekular menggunakan analisis spetrofotometer inframerah. Hasil penelitian diperoleh berupa komposit tekstur dan warna visual yang berbeda-beda sesuai dengan jenis kation yang diemban, komposisi sampel yang dihasilkan dapat dijadikan dasar pengembangan material komposit berbasis material alginat/zeolit untuk mensuplai nutrisi bagi tanaman berupa unsur hara mikronutrien seperti Fe dan Zn.
