Abstract

The purpose of this research was to determine the quality control of cassava chips at IKM Gazal Makmur located in the Kotaanyar sub-district, Probolinggo. There were several findings of the type of defect which also became the reason why this research was carried out. The types of defects found consisted of burnt products, crushed products and product defects in the form of scraps. This research uses the Six Sigma method with the DMAIC Define, Measure, Analyze approach, and is limited to the Improve stage. The results show that the most types of defects are in the cassava chips production process. There were product defects in the form of 67.2% remaining pieces, 19.0% crushed chips and 13.8% burnt chips. Based on the calculation of the final yield, the results of the analysis are 82.7% for frying, 76.2% for packaging and 15.7% for chopping. The results of the analysis of the causes of product defects are damage due to unsharp blades and careless handling when inserting the product.

Abstract

The purpose of this research is to find out the application of Statistical Quality Control and Fault Tree Analysis methods to control the types of defects that occur during the sterilization process, find out the causes of their occurrence, and provide suggestions for improvement. The research methods used were research preparation (literature study), field observations, problem solving, interviews, data collection, data processing, and data analysis. Application of the Statistical Quality Control method to control the types of defects that occur by using the seven tools. While the application of the Fault Tree Analysis method is by making a fault tree and determining the minimum cut set then analyzing it quantitatively. The results of the fishbone diagram analysis found that there are 3 factors that cause defects in the sterilization process, namely machines, materials, and humans. Proposed improvements to reduce the level of defects that often occur, namely carrying out daily inspection and maintenance of the machine, the machine must be calibrated, carrying out more thorough checks on cans sent from suppliers, disciplining employees by holding briefings once a week, conducting training on how to handle them properly and correct every 3 months or 6 months to employees, the seamer operator monitors the time during the draining process to the seamer process, checks the seamer machine before using the production process so as not to hinder the can closing process, and performs temperature sensors on a monthly basisThe purpose of this research is to find out the application of Statistical Quality Control and Fault Tree Analysis methods to control the types of defects that occur during the sterilization process, find out the causes of their occurrence, and provide suggestions for improvement.

Abstract

A purple leaf or possibly called a wungu leaf (Graptophyllum pictum) is a commonly used plant as an herbal medicine. Purple leaves have many benefits, and it is known that one can potentially counteract free radicals caused by high flavonoid compounds. One of the key stages in simplishing is the drying method. The study aims to identify the effects of temperature and long periods of drying as well as variations in temperature and length of time on the flavonoid, the sensory properties (color, scent, taste, and texture), water levels, and rendement on the dried purple leaves using fast dryer. The design of the experiments is a Randomized Block Design (RBD). The first factors are drying temperatures consisting of 45°C (C1), 50°C (C2), and 55°C (C3). The second factors is drying time of 3 hours (F1), 4 hours (F2), and 5 hours (F3). The data analysis is done using a ANOVA and if the results show a real difference then a nt test with a 5% confidence level. Studies indicate that the higher the temperature and time spent in drying, the greater the levels of flavonoid and sensory properties and the lower the water content and rendement in dried purple leaf.

Abstract

Flour premix cookies are used as an alternative to making processed food in an instant way. Flour premix cookies are made by mixing mocaf, sago, powdered sugar, milk powder, and baking powder. This study aims to determine the relationship between mocaf and sago formulations and different roasting temperatures on the value of water content (premix flour), texture (cookies), and organoleptic (cookies) based on the best formulation. Formulation of mocaf and sago as the main factor F1 (75:25), F2 (50:50), and F3 (25:75) and roasting temperature as the second factor P1 (no roasting), P2 (700C), and P3 (800C). This resulted in 9 treatments P1F1, P1F2, P1F3, P2F1, P2F2, P2F3, P3F1, P3F2, and P3F3. The results of this study are that the higher the roasting temperature, the lower the water content, texture, and the decrease in the level of preference.

Abstract

Wheat flour is widely used by Indonesians as a basic ingredient for making bread, triggering the ever-increasing import of wheat flour. Therefore, it is necessary to have other alternatives to reduce dependence on the use of wheat flour. One of them is the utilization of coconut pulp waste which is processed into flour and then processed into pancakes with nutritional value and good quality. The purpose of this study was to analyze the effect of the addition of coconut pulp flour on the physical, chemical and organoleptic characteristics of pancakes and determine the best formulation in making pancakes. This study used a Randomized Group Design consisting of 5 treatments (0%, 10%, 20%, 30%, 40%). The results showed that coconut pulp flour gave a significantly different effect on fiber content, texture, specific volume, color a, color b and hedonic test as evidenced by further tests using the Duncan test at the 1% level. While the water content, ash content and color L test showed no significant difference.
