Abstract

This study aims to analyse the efficiency of the teppanyaki production process for the Nishimura teppan beef steak set menu at Nishimura Restaurant, Shangri-La Hotel Surabaya, by reviewing three main indicators, namely material usage, production time, and labour. The study uses a quantitative descriptive approach supported by qualitative data. Data collection was conducted through direct observation of the production process, recording of raw material usage, measurement of time at each stage of production, and interviews with chefs and related parties. Quantitative data were analysed descriptively using material efficiency percentage calculations, while qualitative data were analysed through reduction and interpretation of work phenomena to reinforce quantitative findings. The results showed that material usage had reached an efficiency level with a yield percentage of 81% and waste of 19%, reflecting controlled raw material management in accordance with quality standards. In terms of time, all stages of pre-preparation and live cooking can be completed on time without disrupting service. Labour efficiency is demonstrated through the adaptive use of working time, characterised by minimal idle time. Overall, the teppanyaki production system is considered efficient and supports the smooth operation of the restaurant

Abstract

Post-production food waste is a common issue in hotel dinner buffet services due to leftover food remaining after service has ended. This study aims to examine the condition of post-production food waste, the control measures implemented, and the indicators of successful post-production food waste control in the dinner buffet service at Pavilion Restaurant, JW Marriott Hotel Surabaya. This study employed a descriptive qualitative method, with data collected through interviews, observations, documentation, and post-production food waste weighing conducted over a 10-day observation period. The findings indicate that post-production food waste originated from leftover food on the buffet line, food remaining after service, and food that could not be reused due to food safety standards. The contributing factors included overproduction, the characteristics of buffet service, inaccurate buffet replenishment, and the implementation of food safety standards. The total post-production food waste generated during the study was 46.111 kg, with an average of 4.611 kg per day. Food waste control was implemented through production planning, guest forecasting, Final Guest Count, Standardized Recipes, Portion Control, Batch Cooking, buffet replenishment, and buffet line monitoring. The success of food waste control was indicated by production accuracy, reduced overproduction, and a reduction in post-production food waste, thereby improving operational efficiency and minimizing food waste in the dinner buffet service
