Abstract

In general, the purpose of this e-module is to limit the use of paper in making learning modules that are appropriate to the teaching material, and the specific goal is how to make learning material packaged in an attractive form. The most fundamental problem is that students are not interested in learning by using modules in text form, plus they prefer applications on smartphones, especially Android. However, most books and modules can be read through the gadget in pdf or epub format. However, from the children's point of view, it would be more interesting if it was packaged in digital multimedia that involved animation and sound. This research was built using the Luther Sutopo method, which involved six stages. The results of the research are digital module applications based on Android. Testing of this e-module application was conducted on several elementary school children, with 90% results being able to do the quiz correctly.

Abstract

In this study, the object was taken regarding a web-based community service information system in Kuala II Village, Sui Raya District. In the process of serving the community, especially in the field of making certificates in Kuala II Village, Sui Raya District, previously it was still using a manual system. Where people have to come to the sub-district office and fill out a form and come back again to inquire about the processing and also still have to come back to pick up the results. With this manual system it causes less efficient time. So a study was conducted with the aim of creating a new system that could help and speed up the process of service to the community in Kuala II Village, Sui Raya District. In this research analysis, new information was generated, namely a web-based community service information system in Kuala II Village, Sui Raya District. With this system, it is hoped that it will expedite work and facilitate the community in the process of making services. The conclusion obtained with this new system is that the community can speed up the process of making a statement from the Jelupang Village. While the advice that must be considered is the need for human resources who can run and develop the system properly.

Abstract

Discord has shut down 30,000 communities due to various violations. In addressing the misuse of the Discord application, particularly in the form of sexual harassment, the problem of how to retrieve deleted messages from Discord desktop conversations using the National Institute of Standards and Technology (NIST) SP 800-86 method can be addressed. The NIST (National Institute of Standards and Technology) SP 800-86 method is employed for conducting digital evidence analysis or the process of obtaining information from digital evidence. The stages of the NIST method are Collection, Examination, Analysis, and Reporting. The accuracy level of the files obtained using the FTK Imager application is 16.67%, with the variables being evidence of image files. On the other hand, the ChromeCacheView application achieves 73.33% accuracy with variables including evidence of image files, videos, text messages, accounts, and emails. However, not all text messages are retrieved by ChromeCacheView. Autopsy, with a score of 33.33%, manages to retrieve images and emails.

Abstract

The ability to process data is to process raw data into useful information for users, in this case, PT. Mod Indo finds it difficult when making procurement decisions because there are factors that must be considered, namely the expenditure of goods, the need for goods, and the allocation of goods. The absence of a patented system causes some employees to frequently use estimates so that excess inventory often occurs for a long time which results in damage to goods. To realize better performance, it is necessary to build a decision support system in the supply of goods stock. This study aims to design and build a decision support system to help control inventory at PT. Indo mod. The system developed uses the programming language PHP and MySQL as a database, using the ABC Analysis Method which is a calculation of the distribution of classes based on the value of an item. In the study, testing 100 data on this system produced a cumulative 78.98% cumulative item group A category with 15 total items, 11.05% cumulative item B group with 10 total items, and item C group 9.97% cumulative 75 total goods. Classification of goods produces appropriate data, namely in the form of data that has the highest priority to be controlled. With this system, it can help PT Mod Indo to track, plan, and control inventory optimally, so that it can identify goods with fast, medium, and slow turnover, and can increase work efficiency and production for employees

Abstract

In developing countries, chronic malnutrition leads to stunting. Stunting will become a public health problem in Indonesia resulting in a decline in the quality of Indonesia's human resources in the future. In the modernization era, determining the nutritional status of toddlers can be simplified automatically. The author's C4.5 algorithm was used to classify and predict the nutritional status of toddlers in Bringin sub-district, in addition to testing using the system that the author built, the author also conducted manual testing and testing using RapidMiner as a comparison. Based on the analysis of the results of 186 datasets tested using this system, predictions were made of toddlers with male gender categories, very underweight and height predicted that the toddlers were in the malnutrition category. For the performance of the dataset tested obtained an accuracy of 84.221%, there was a difference of 6% from the test results using RapidMiner which obtained an accuracy of 91.40%. The use of algorithms is highly recommended to classify the nutritional status of toddlers. The application of the toddler nutritional status classification system that the author designed is feasible because it can be faster and more effective in classifying the nutritional status of toddlers based on the zscore set and there is only a difference of 6% from the same dataset prediction testing using rapid miner. Based on the dataset of system test results, it can be concluded that 89.24% of toddlers in Bringin sub-district are well nourished.

Abstract

Tenun Resti Sipirok is a company engaged in trading woven products such as Jas, Ulos, Souvenirs and other woven products. In marketing its products, Tenun Resti Sipirok still uses the shop as a marketing place, so that consumers who are interested in buying these products must come directly to the store where they are marketed. Not infrequently consumers are disappointed because the product they want to buy is not available which requires consumers to order in advance until the product is finished being produced. By designing and implementing a web-based marketing system with a CRM approach to Tenun Resti Sipirok, it is very helpful in the process of marketing products via the internet, such as selling and promoting products to consumers. This also has a positive impact on the consumer side, because consumers do not have to come directly to the marketing shop, but consumers can buy and order products through the website that is created and information about new products and promos is easy for consumers to get through the website page as well as via email messages.
