Abstract

This research aims to determine the historical pattern of sales of each product variant, the index of special events that influence the demand and forecasting models are most appropriate to use as the basis for planning the production of Coca-Cola 200 ml and Sprite 295 ml in PT. CCBI Balinusa. From these studies obtained pattern on the monthly sales of each product in 2015 fluctuated from time to time. The highest sales of Coca-Cola 200 ml occurred in September, and Sprite 295 ml occurred in December. While the lowest sales data on Coca-Cola 200 ml and Sprite 295 ml occurred in July. Index top special event for Coca-Cola 200 ml is on Christmas and New Year (I=2.43), the lowest was Idul Adha (I=1.42) and Sprite 295 ml highest at Christmas and New Year (I=2.17), the lowest in the Waisak (I=1.47). The best forecasting model for Coca-Cola 200 ml is an exponential smoothing event based (ESEB) with α = 0.3 and for Sprite 295 ml is an exponential smoothing event based with α = 0.1.

Abstract

This research aimed to (1) determine the effects of roasting temperature and duration on the physical characteristics and sensory quality of Arabica coffee beans, and (2) determine the roasting temperature and duration that produce the best physical characteristics and sensory quality of Arabica coffee. The experiment was conducted using a factorial completely randomized design with two factors. The first factor was roasting temperature, consisting of three levels: 220°C, 235°C, and 250°C. The second factor was roasting duration, consisting of three levels: 14, 17, and 20 minutes. The variables observed in this study were yield, moisture content, color (CIELAB), acidity, and organoleptic properties. The results showed that roasting temperature and duration significantly affected yield, moisture content, color value, acidity level, aroma, taste, and color of Arabica roasted coffee. The roasting temperature of 235°C with a duration of 14 minutes was the best treatment, producing roasted coffee with the best physical characteristics and sensory quality, namely 82.5% yield, 1.08% (w/w) moisture content, 6.51 color value (Lightness), 5.84 acidity, aroma score of 3.6 (between moderate and like), taste score of 3.2 (between moderate and like), and color score of 3.6 (between moderate and like).
