Abstract

Abstrak Kopi liberika tersebar luas di Sulawesi Selatan, khususnya di Bantaeng. Namun, penanganan kopi yang tidak tepat dapat mempengaruhi kualitas kopi dan rasa yang dihasilkan. Salah satu proses terpenting dalam meningkatkan kualitas kopi dan menciptakan cita rasa yang nikmat adalah proses penyangraian dan penggunaan suhu serta waktu penyangraian harus diperhatikan. Tujuan dari riset ini adalah mengetahui pengaruh suhu dan waktu sangrai terhadap sifat fisikokimia dan mutu sensori kopi liberika. Riset ini mempergunakan eksperimen dengan pendekatan kuantitatif. Rancangan Acak Lengkap (RAL) pola faktorial dipergunakan dipergunakan dengan perlakuan variasi suhu sangrai 180, 200, dan 220˚C, dengan waktu 10, 12, dan 14 menit. Sejumlah variabel penelitian ini diantaranya kopi hedonik Liberica, gula total, kadar abu, kadar kafein, pH, kadar air dan rendemen. Data yang didapat lalu dianalisa dengan sidik ragam dan uji lanjut DMRT (Duncan Multiple Rate). Penelitian menghasilkan perlakuan variasi suhu dan waktu penyangraian mempengaruhi rendemen, kadar air, pH, kadar kafein, kadar abu, total gula, warna, aroma, dan rasa kopi liberika. Tapi suhu penyangraian tidak berpengaruh pada kadar abu kopi bubuk liberika.

Abstract

This study aims to analyze quality and risk management related to product defects in dry cakes produced by Bakers King. The research was conducted through a three-month survey (February–April 2022), covering a total production of 10,646 units, with 564 defective products identified. The three main types of defects were overflow (54.4%), burnt (23%), and crumbled (22.5%). Analytical methods used in this study included a P-chart for statistical quality control, a fishbone diagram to identify root causes, and Failure Mode and Effect Analysis (FMEA) to evaluate potential risks in the production process. The FMEA results indicated that the highest risks stemmed from inconsistent recipe use (RPN 240) and data recording errors (RPN 224). Proposed mitigation strategies included regular staff training, digitalization of data recording, implementation of standard operating procedures (SOPs), and regular equipment maintenance. Meanwhile, risk transfer strategies were carried out through quality contracts with suppliers and product insurance. This study recommends a comprehensive improvement in quality management systems to reduce product defects and enhance customer satisfaction.
