Abstract

The current competition in the food industry encourage companies to be able to produce products that are diverse, in a good quality, and in a timely manner to meet the company's production targets. PT XYZ is a food company in Indonesia. To be able to meet production targets, companies must adjust their production capacity by utilizing their workforce. However, the problem is that there are so many variables involved in the system so that the problem becomes more complex and hard to solve. Therefore in this study, a dynamic system approach is used to be able to see the interactions between variables in the system using Vensim software. Based on the research that has been done, the values ??of E1 < 6% and E2 < 2.5% indicated that the data used in this research is valid in other words the model used has represented the real system conditions. From the research, the best result is to gradually increase the installed capacity so that there is no over production occured. Using this scenario, the availability of raw materials for is 5901 boxes.

Abstract

Molluscan shellfish can accumulate natural poison produced by marine algae, one of which is brevetoxin (BTx). BTx is a toxin produced by marine dinoflagellates of the Karenia genus, especially Karenia brevis, which has the characteristics of being fat-soluble, lipophilic, colorless, tasteless, and very heat stable. Based on the backbone structure, BTx is classified into BTx-1 and BTx-2. BTx-2 is the most common type of toxin produced by K. brevis. BTx was synthesized from a polyketide synthase pathway that could potentially incorporate larger carbon units of acetate modified by the citric acid cycle. BTx poisoning causes neurologic shellfish syndrome (NSP), which is characterized by major symptoms in the neurological and gastrointestinal systems. NSP is due to the high affinity of BTx in binding to receptors on the cell wall, namely voltage-gated sodium channels (NaV). Based on the food safety risks posed, monitoring programs to detect the growth of harmful algae and the presence of brevetoxin in food should be implemented. Several detection methods have been developed, such as mouse bioassay, cytotoxicity assay, receptor binding assay, immunoassay and LC-MS/MS.

Abstract

XYZ Village is an industrial village that produces woven fabrics. Failure in the production process is something that must be traced to the cause so that it can be used as a basis for improving product quality. Total Quality Management (TQM) is an approach to running a business that tries to maximize the competitiveness of an organization through continuous improvement of products, services, people, processes, and the environment. This study was conducted to identify potential causes of failure and improve the quality of woven fabrics in the weaving process in XYZ Village with the TQM method approach. Based on the calculations that have been done, it was found that there are two valid variables and two other invalid variables because the value of r-count > r-table, namely the variable color is less bright and the color is mixed. Then the main factors that cause the quality of woven fabrics to decrease and result in production failures on woven fabrics are inappropriate battens and also color spots on woven fabrics.

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

Mesoporous silica is continuously raising in popularity due to its excellent and unique properties, such as customizable pore, surface shape/morphology, large pore volume, and ease of functionalization for wide applications like catalysis, energy, environment, and biomedical areas. In the templated growth synthesis, a template acts as a mesostructure-directing agent to produce hollow porous structures in silica frameworks. Templates can be divided into "hard" and "soft" templates. While soft templates are typically in a fluid-like condition and hard templates are typically solid-state materials with specific morphology and structure. In this minireview, we summarize the synthesis method of mesoporous silica with a soft-hard template approach (template-assisted method).
