Abstract

This e-module was developed based on problems that occur during the learning process, the teaching materials used are still not optimal and some materials are not following the characteristics of students and learning objectives. Students are also less active in participating in the learning process and cannot collaborate in solving a problem, so it is necessary to develop relevant and innovative Project-Based Learning-Based Interactive E-Modules to help students more easily understand learning materials, be active in the learning process, and improve independence in learning. The method used in this research is research and development (R&D) by adopting the 4D (Four-D) development model which includes 4 steps, namely: define, design, develop, and disseminate. By definition five activities must be carried out, namely: 1) Initial analysis, 2) Student analysis, 3) Task analysis, 4) Concept analysis and 5) Formulation of learning objectives. In the design four activities must be carried out, namely: 1) Preparation of test standards, 2) Selection of media, 3) Selection of formats, and 4) Initial design. In development two steps must be done, namely: 1) Expert assessment, and 2) Development trial. And the last is dissemination, this stage is the dissemination stage to promote the product developed so that it is accepted by users, individuals, groups, and systems. The results of the research and development of project-based learning-based interactive e-modules can be seen from the validity tests of both media and materials that have been carried out with an average media validity value of 0.86 (valid), and an average material validity value of 0.78 (valid).

Abstract

The rapid development of technology today is very possible for the occurrence of various forgeries and frauds that are carried out to take profits unilaterally. One of them is the falsification of a certificate of appreciation that canbe easily carried out by irresponsible parties. An award certificate is an important file that proves theachievements of a person in a particular activity or competition. This is what gives rise to a lot of people who tryto forge certificates of appreciation for their personal interests, both work and education. Therefore, a system isneeded to test the authenticity of the award charter. With a series of testing steps carried out, it can be concludedwhether the award certificate is authentic or not. To avoid falsification of document files, it is necessary to applya digital signature with a cryptographic method. Digital signatures or better known as digital signatures can helptest the authentication of a document, especially a certificate of appreciation. When the digital signature has beenapplied to the award certificate, the award recipient can check whether the file is authentic or has been modified.The application of digital signatures goes through 2 stages, namely the signing and verification process. Signingis the stage of forming a digital signature by combining the SHA-3 and ElGamal algorithms. The authenticity ofthe file can be seen by carrying out the verification process, which is the process of comparing the hash value ofthe received file with the actual file hash value. This research produces an analyzation about process ofauthentication using digital signature.

Abstract

Document files with the .RTF format are files that are quite often used but have a fairly large size. Large file sizes often experience problems when sending files where the sending process can take a long time and can consume a lot of storage space because too much large data is stored. This is certainly very difficult if there are many files that must be stored, while the storage media has a size limit. To overcome this problem it is necessary to do compression to compress the data. To choose the optimal algorithm for compressing document files, it is necessary to compare the Huffman algorithm and the Levenstein algorithm by measuring performance based on the Ratio Of Compression (RC), Compression Ratio (CR), Redundancy (Rd) and Space Saving (SS). After the calculation, the results of the most optimal algorithm in compressing document files are obtained, namely the Huffman algorithm with higher space saving and lower compression results compared to the Levenstein algorithm. This is because the greater the space saving (ss) the compression is getting better and faster.

Abstract

The impact of the Covid-19 pandemic that is felt by the community is the paralysis of all daily activities. As a result, the cessation of work for a long time causes the company's economy to cripple and results in many companies losing money and making Termination of Employment (PHK) for employees or employees. For the heads of families, the termination of employment (PHK) experienced, of course, has a fairly heavy impact. There are many bad impacts caused by Termination of Employment (PHK) such as not being able to continue education for children, especially in college due to not being able to pay tuition fees every semester. Therefore, to overcome this problem, the government created a Single Tuition Assistance (UKT) program. However, the UKT assistance provided by the government was not able to cover all the financing needs for students who were affected by the Covid-19 pandemic. Limiting quotas for recipients of Resident Tuition (UKT) assistance for Budi Darma University is a new problem, of course. Decision Support System is a computerized system on a computer that is used to support decision making in organizations. The Weighted Aggregated Sum Product Assessment (WASPAS) method is a combined method consisting of the WP method and the SAW method, the WASPAS method is expected to provide better results in helping to determine the decision support system. To support obtaining optimal and objective results, a weighting method is needed, namely the ROC method. Based on the above discussion, the research that will be carried out is to select students who receive Single Tuition (UKT) assistance. The results showed that the four alternatives with the highest preference scores received UKT assistance, namely A6, A5, A4, A3

Abstract

In the world of work, competition certainly exists. Especially in the selection of the location of the business being run. The better the location of the place of business, of course, the more competition. In this study, we will discuss the selection of a strategic and appropriate business location. The location of the business greatly affects the development of the business being run, many businesses do not develop (loss) so they have to stop their business because the location of the business is far from residential areas, the location is narrow and so on. To avoid this, we need a system that can solve the problem which is called a decision support system. Decision support system is a structured system in making effective business location selection decisions using methods such as WASPAS, SPI, TOPSIS, WP, SAW, MOORA, MOOSRA, EDAS and many others. The selection of business locations used the MOOSRA and MOORA methods. Both methods are very simple and easy to understand with the assessment based on the criteria used, namely Number of Competitors, Crowd Center, Location Size, Place Rent Price and Location Cleanliness. The results obtained after applying the two methods in the selection of business locations, namely the highest alternative or the first rank is Alternative A1 with a reference value of 0.564

Abstract

Acceptance of new employees at PT Exprvet Nasuba Medan is one of the routine activities carried out every year, in order to find reliable candidates. The problem that occurs is that the selection is still random, not objective and impure, because it is caused by a third party in the recruitment of new employees. So that the decisions taken can trigger a tendency towards subjectivity in one of the prospective registrants which results in brokering at the selection stage. To overcome this problem, a Decision Support System (DSS) was developed that used a combination of the ANP-TOPSIS method in selecting and accepting new employees by finding the best solution based on that method. In this study, the ANP was used to assign a weight to each criterion. The weight is calculated by the TOPSIS method of ranking. Based on the results of the ranking calculations obtained using a combination of the ANP-TOPSIS method. The highest score obtained based on alternative criteria and data, showing the highest preference value is Sukur Jaya Sinaga with an average score of 0.9182 as a rank 1, Hemansyah with an average value of 0.6666 as a rank 2. And Rudi Kesuma with an average score The average is 0.6648 ranking 3. So that it can be concluded from the results of the calculations of the two combinations of the ANP-TOPSIS method, that Sukur Jaya Sinaga is ranked first and the highest value is based on the results of the weighting of the ANP method and then calculated by the Topsis method for ranking.
