Abstract

Food safety issues are still an important issue in the food sector in Indonesia and need special attention in food control programs. Therefore, it is necessary to improve the quality and safety of the products produced by developing a food safety assurance system in the form of a Hazard Analysis and Critical Control Point (HACCP). HACCP is a food safety assurance system in the form of a systematic approach to identifying hazards and put in place control systems to prevent them. One of the important reasons for implementing the HACCP system in the food industry is because the ingredients used during the production process have the possibility of contamination that can harm consumers. Cu's Chicken Crispy is a small industry that produces food. His party wants to implement a Hazard Analysis Critical Control Point (HACCP) management system to improve product quality assurance. This study aims to identify hazards related to the production aspects (raw materials, packaging, and processes) of Cu’s Chicken Crispy and determine the CCP related to the production of Cu’s Chicken Crispy. This study conducted a direct interview with the owner and made a direct visit to Mrs. Cu's food stall. In this study, it was found that there is a significant potential danger to chicken meat raw materials. At the stage of the production process that falls into the category of salting, draining and packaging refer to CCP.

Abstract

Liquid smoke is obtained from the condensation of smoke resulting from burning biomass during the pyrolysis method. Biomass that can be used in the process of forming liquid smoke has the characteristics of containing cellulose and lignin. Liquid smoke contains ingredients that can be used as antimicrobial substances, namely phenolic compounds. The method that can be used to increase the phenol content in liquid smoke is the adsorption and distillation method. This research aims to increase the phenol content in the liquid smoke with a stage I purification process, namely, adsorption using an activated carbon adsorbent, and stage II purification, namely distillation at a temperature of 120 °C. The variables used in the research are variations in pyrolysis time (250°C, 300°C, and 350°C) and pyrolysis time (1 hour, 1.5 hours, and 2 hours). The results showed that liquid smoke experienced changes in the amount of phenol content. The highest phenol content obtained occurred at a variable temperature of 350 °C over 2 hours, amounting to 23.10 ppm, and increased after adsorption and distillation to 27.20 ppm. Changes in pH, density, and color in liquid smoke occur after distillation and adsorption, where the highest pH is 4.9, the lowest is 3.7, the highest density value is 1.011 gr/ml, and the lowest is 0.993 gr/ml.

Abstract

The bio briquette is a type of briquette that is derived from agricultural waste since it is intentionally produced using biomass charcoal. The processing of agricultural waste, such as mushroom planting material, into bio briquettes is characterized by its low cost. When bio briquettes undergo appropriate and accurate processing, they can yield briquettes of superior quality. The primary objective of this research endeavor was to generate a biobriquette using an agricultural byproduct derived from mushroom farming, while concurrently assessing the distinct attributes and properties of said biobriquette. The research utilized a total of 400 grams of waste from mushroom culture materials, together with an adhesive composed of 40 grams of starch. The briquette dough is subsequently extruded in a cylindrical shape. Subsequently, the mold briquettes are subjected to a heating process at a temperature of 80°C for 5 hours, to decrease the moisture content. The outcome of the smoke test indicates that the emission of smoke will cease after 75 seconds. In the conducted Combustion of Speed Test, the obtained findings indicate a combustion rate of 0.425 grams per minute, using an initial sample weight of 5.8 grams. The ash content yielded a reading of 10.6%.

Abstract

Bioethanol is an alcohol molecule that is derived through the process of fermentation using microorganisms. Fermentation is a biological process in which microbes metabolize fermentable sugars as a source of nourishment, resulting in the production of ethyl alcohol and various other byproducts. These microbes commonly metabolize 6-carbon carbohydrates, with glucose being one of the most prevalent examples. Hence, biomass materials rich in glucose or glucose precursors are the most readily convertible to bioethanol. The examination of bioethanols employing Saccharomyces bayanus demonstrated notable disparities in the obtained alcohol concentration. The utilization of Saccharomyces bayanus yeast, in the absence of sugar supplementation, for the conversion of grape into bioethanol, yielded a modest alcohol concentration of merely 14%. In the context of bioethanol production, pineapple was utilized as a substrate, wherein 4 grams of Saccharomyces bayanus yeast and an additional 70 grams of sugar were introduced as a nutritional supply to support yeast growth and metabolism. The present fermentation procedure resulted in an alcohol concentration of around 21%.

Abstract

Bio-based waste materials perform an essential duty as valuable sources of components that can be effectively utilized as active phases in the synthesis of CaO catalysts for the generation of biodiesel. The abundance of shell Blood cockles is considerable. Additionally, Indonesia has a stockpile of used cooking oil. The utilized cooking oil has a notable concentration of fatty acids, presenting the potential for conversion into biodiesel. The technology of converting leftover cooking oil into biodiesel through transesterification has undergone significant advancements. An accelerator is necessary to boost the biodiesel yield to attain a sufficiently high yield. The CaO catalyst was selected due to its ability to expedite and boost biodiesel output. This study evaluated the blood clam shell's potential as a transesterification catalyst for used cooking oil. This study used temperature and concentration change variables for transesterification, with a settle variable of 60 minutes. The concentrations of the variables are 3 N, 4 N, 5 N, 6 N, and 7 N, whereas the temperatures are 45 ?C, 50 ?C, 55 ?C, 60 ?C, and 65 ?C. With varying transesterification times of 60 minutes, transesterification temperatures of 60°C and 65°C, and catalyst concentrations of 6N and 7N, the research findings indicate that utilizing this catalyst can boost biodiesel yield with conversion yields of 85%, 88%, and 95%. This demonstrates that temperature can also promote improving biodiesel production and that using catalysts can boost the conversion of biodiesel to over 90% or more.
