Abstract

L-Arabinose isomerase (L-AI) is a type of intracellular enzyme catalyzes the reversible isomerization reaction of L-arabinose to L-ribulose, besides that it can convert D-galactose to D-tagatose. One of the bacteria that can produce this enzyme is Geobacillus stearothermophilus. The high price of instant media, which reaches IDR 1,500,000 to IDR 3.000.000,- for every 500 g and the abundance of natural resources that can be used as a medium for the growth of microorganisms encourages researchers to find alternative media from materials that are easy to get and do not require expensive costs. The researchers compared the effectiveness of liquid Luria Broth (LB) media and molasses media for enzyme production. The research involved inoculating bacteria in both media types, followed by subculture and incubation. IPTG was added to induce enzyme production, followed by cell harvesting through centrifugation and sonication. Enzyme activity was evaluated using SDS PAGE and the cysteine carbazole method. Molasses showed promising results due to water solubility, enzyme activity, abundance, and cost-effectiveness. Molasses appears as an alternative with active enzymes, water solubility, abundant availability, and significant cost savings, making it a viable choice for enzyme production.Keywords— L- Arabinose Isomerase, Molasses, Enzyme

Abstract

In the fishermen's environment, in general, fresh fish is preserved so that it does not spoil quickly by using ice, but the durability of ice is limited, so fishermen usually add formalin; formalin is generally used as a preservative for corpses and is prohibited from being added to food. Nipah leaf extract is very good to be used as an anti-bacterial compared to the fruit, so that it can be used as a natural preservative. This study aimed to determine the optimum concentration of the addition of crude nipa leaf extract on the quality of fresh milkfish. The sample in this study used milkfish preserved using nipa leaf extract as a natural preservative. This research was divided into two stages, namely, in the first stage, it was used to find the best concentration in making nipah leaf extract solution, and the second stage was carried out to determine the effectiveness of nipa leaf solution as a natural preservative. This study found that Nipah leaf extract with a concentration of 22.5% could increase the shelf life for 24 hours with a bacterial growth rate of 5.63±0.03 log cfu/g. This study concludes that Nipah leaf extract can inhibit decay in milkfish.Keywords— milkfish, nipah, anti-bacterial

Abstract

Enterprise Resource Planning (ERP) is an integrated management information system that can provide specific information system requirements for each department in a company. However, its implementation requires high costs, so some companies switch to using Open ERP. Seeing this, Al-Azhar Indonesia University began to integrate its data by creating an ERP system called Application World Wide (AWW) at the Directorate of Facilities and Infrastructure. However, based on the results of interviews with the staff, it was stated that, in the management process, all Purchase Order (PO) data recorded in the system could not be downloaded, so the staff recorded data manually. To overcome this, it is necessary to develop an ERP system to support the procurement process, so that the process of recording and storing documents can be well integrated. In this study, the authors used the ERP system implementation, namely Rapid Application Development (RAD) and used the Odoo software version 16.0. A User Acceptance Test (UAT) is also carried out to find out whether the system meets the user's needs or not. After implementing Odoo at the Directorate of Facilities and Infrastructure at Al-Azhar University Indonesia, it can be concluded that all procurement activities can be recorded in a complete, correct, up-to-date, and valid/legal manner due to the implementation of the Odoo ERP system which is integrated and adapted to user needs, such as customize 4 of 12 features in the purchase module. Then with the purchase report module it can simplify the process of recording, and reporting PO data. Based on the UAT results, it can be seen that the whole question have an average score of 4.22 so it can be said that the user understands how to operate the Odoo ERP system and the features in Odoo can meet user needs.Keywords – Enterprise Resource Planning (ERP), Odoo, Rapid Application Development (RAD), User Acceptance Test (UAT)

Abstract

Casting machine is a production tool with the function of molding liquid aluminum into velq products used at PT XYZ. In carrying out the production process, casting machines often experience failures that affect the high machine downtime and also the ineffective use of machines to run the production process. The purpose of this research is to implement Total Productive Maintenance by analyzing the use of machines with the OEE method to determine the value of their effectiveness and conducting breakdown analysis using the 5 why's analysis method to find the root of the problem that affects the calculation of the OEE value of the machine so that a solution can be formulated to overcome these problems. Based on OEE calculations on the casting machine for the January-June 2022 period, the performance rate measurements in January and May were 89. 19% and 83.28% which were below the Nakajima standard. The results of the May performance rate calculation have an impact on the OEE value which does not reach the standard of 82.17%. By using 5 Why's analysis, the cause of the low performance rate value in both months is the operator who makes changes to the machine settings so that the actual cycle time of machine operation is higher than before and causes reduced speed losses.Keywords - Casting machine, OEE, performance rate, 5 why’s analysis, reduce speed losses
