Abstract

In this study, we evaluated the limitations of using learning resources that can be used in a Learning Management System (LMS) platform, which cannot be packaged and can be used again in processing, combining, and rearranging learning based on learning objects that already exist in different LMS platforms. Studying content with formats other than SCORM is not easy adapted to the needs because the content must be reorganized every time using a different platform. Therefore, it is necessary to analyze and design learning according to the SCORM format to meet the ISO 19796-1 standard platform. This standard has the ability to share, reuse, and interoperate learning objects. The challenge in the world of education today is how to build a knowledge-based society. The building of e-learning plays an important role. Currently, the e-learning portal is a very diverse learning management system (LMS) platform used by schools or tertiary institutions. In addition, the types of learning resources and content are also diverse. It does not meet the e-material design requirements based on mechanisms that can be shared, reused, and operated on different platforms to meet the granularity element. The results provide insight and highlight the mismatch between digital learning and digital asset standards, especially in Indonesia. This helps us analyze, design, develop, and submit digital assets for electronic learning materials in vocational high school software expertise programs in accordance with SCORM Standards.

Abstract

Coal is widely used as an energy source in several industries, especially for power plants (PLN), but on the other hand this causes waste problems or environmental impacts. Several studies have been carried out to utilize coal ash waste (fly ash) as an additional material [or as a partial substitution material] in making mortar. This research aims to determine the effect of adding coal ash and rice husk ash with variations of 5%, 10% and 15% of cement weight respectively (at ages 3 days, 7 days, 14 days, 21 days and 28 days). on the 'compressive strength' and 'absorption capacity' values of the mortar. This research uses quantitative methods through a series of experiments on 60 samples or test objects with the addition of coal ash (fly ash) and rice husk ash in the mortar mixture with reference to the Indonesian National Standard (SNI 03-6825-2002). Next, a series of tests were carried out at the age of 3 days, 7 days, 14 days, 21 days and 28 days to calculate the ' strong ' value. press' and ' power absorb' mortar. The research results showed that with the addition of coal ash and rice husk ash, the mortar experienced a significant increase in 'compressive strength' when compared to ordinary mortar, the strength of the mortar reached the optimum level at a variation of 15% addition of the cement weight, reaching 240.96 kg /cm 2 . Meanwhile, with the addition of husk ash in the same variation, the compressive strength of the mortar reached 204.82 kg/cm 2 .

Abstract

The cash processing administration system in a company plays a very important role. One of the problems that often arises in a cash processing administration system is the inaccurate calculation results of cash administration reports. This can result in inaccurate calculations of a company's profits and losses. Besides that, the use of company funds for something is not necessary, because every income and expenditure of company funds can be seen clearly and can be checked at any time. In short, companies will be able to quickly and easily find out the income and expenditure of funds. Information technology which is developing rapidly at this time provides very helpful benefits for the development of a company's information system, especially with the use of computer-based information technology, because by using computer technology in an information system you will be able to process data more quickly with lower error rates. minimal and saves time. The procedures that will be processed consist of the administration section and the finance section. If there is an income or expenditure of money or funds, the data can simultaneously be entered into the computer and will automatically influence or add to the existing data in the company. In this way, the condition of the money or funds in the company can be known with certainty and accuracy.
