Abstract

The purpose of bread quality control is to determine the number of defects in bread during production so that causes and solutions can be found to solve the problem. The control chart method and the Pareto diagram were used to determine the product defect. The Control Chart method aims to determine the control of defective products, whether the production process is still within the control limits or outside the control limits and to find out how to control defective products. This study contributes to investigating the quality control of bakery products at PT. ABC in Lampung. The results obtained after the analysis using the P-Chart control showed that the defect bread data was still within the limits of LCL and UCL. By using the Control Chart method, it shows that the product is still within the control limits. The fishbone diagram method contains several factors that cause defects on the bakery products. These factors include materials, people, machines, and processes. The main factor that is very influential in causing defects in bread is the human factor due to the lack of manpower which causes employees to become tired and lack focus in doing work.

Abstract

In general, cookies are made by using wheat flour with high gluten content, consequently it may cause negative impact on health. So far, cookies also have not the characteristics as functional food that is beneficial for health. Based on these issues, wheat flour is needed to substitute with alternative materials in order to reduce the gluten and increase the functional characteristic of cookies. Mocaf, purple yam flour and cinnamon powder can be used to provide cookies with low gluten and have the characteristic of functional food. The aims of this research are to characterize the physicochemical and organoleptic properties of cookies based Mocaf flour, purple yam flour and cinnamon powder. This work was used he completely randomized design (CRD) with the formulations applied F0(100:0:0), F1(75:24.5:0.5), F2(75:24:1), F3(75:23.5:1.5). F4(50:49.5:0.5), F5(50:49:1), F6(50:48.5:1.5), F7(25:74.5:0.5), F8(25:74:1), and F9(25:73.5:1.5) with 3 replications. Analysis of physicochemical properties of cookies consists of moisture, fat, total protein, ash, carbohydrates contents, texture, and antioxidant activity. The organoleptic properties were tested by 30 semi-trained panelists. The collected data were analyzed by one way ANOVA at significance level of 5% and followed by Duncan's test. These results show the contents of fat, protein, ash, carbohydrate, water, antioxidant activities and hardness were obtained in the range of 28.1-29.4%, 3.3-3.6%, 1.5-2.2%, 59.8-62.1%, 44.5-88.8 ppm and 13.8 - 38.3 N, respectively. Based on the organoleptic tests, F2 cookies was most preference than other formulations. The cookies produced believes have low gluten and food functional properties
