Abstract

The conventional economic system has been developing for a long time, followed by the Islamic economic system which is currently developing rapidly in Indonesia. Sharia economic activities are based on the rules of the Koran regarding right and wrong, good and bad, and halal and haram rules. The background of sharia business ethics is the Prophet Muhammad SAW which is based on the Al-Quran and Hadith. The sharia economy can be seen with the emergence of Islamic banks, almost all major banks in Indonesia have sharia branches. Not only that, e-money and sharia payment gateways already exist. This is based on the large number of Indonesian people who adhere to Islam and the increasing awareness of Muslims in Indonesia in implementing the Islamic economic system. Since March 2, 2020, the Corona virus or Covid-19 pandemic has entered Indonesia. Many employees become unemployed. 50% of MSMEs could go bankrupt in the next few months. Whereas small businesses make a big contribution to the absorption of jobs in Indonesia which creates income for the population. The management of the Semarang City DMI organization took the initiative to ease the burden on the people, especially in the city of Semarang by making the DMI application based on the people's economy. Waterfall is the method used in this research. Waterfall is suitable for application development with a complete needs analysis. After the PSBB period ended, there were many unemployed who tried their luck by selling small businesses and MSMEs opened slowly. It is hoped that the DMI application can introduce the business of the community around the mosque and other people can buy the business easily through the application.

Abstract

The admission activity of new students is an administrative process that is sure to occur every new school year and always repeats every year as a starting point for the search for quality resources in accordance with the criteria of each school. Selection is done manually such as using a spreadsheet or number processor still raises several problems including the length of the selection process. At the time of the participant selection process, it involved many criteria that were assessed (multi criteria). Efforts to assist the school in selecting participants from the results considered to be acceptable results require a decision support system for selecting new students. The method used to support students' selection decisions is AHP and SAW. AHP method is used to determine the weight of predetermined criteria, while the SAW method is used for alternative ranking. The purpose of alternative ranking is who has the right to be accepted as a new student based on predetermined criteria.

Abstract

SNMPTN (State Higher Education Entrance National Selection) is one of the pathways to be able to enter State Universities, this can be proven by the number of students who are interested in being able to enter State Universities with this pathway. SMAN 2 Depok directs their students so that they are not wrong in choosing the chosen State University. But there are still many students who are still doubtful about which university they will choose according to their abilities. With this problem many students end up choosing universities that are not within their abilities. Therefore, by using a Decision Support System which makes decisions based on data held by students can help determine the best university for students. The method used is Weighted Product (WP) and Weighted Sum Model (WSM), the criteria used for this method use the results of semester 1 to 5 grades that have been achieved by students. Using these 2 methods will produce different values for each university and each method will produce different grades. With this, students of SMAN 2 Depok can consider which university they will choose.

Abstract

Social media is currently an online media that is widely accessed in the world. Microblogging services such as Twitter allow users to write about various things they experience or write reviews of a product, service, public figures and so on. This can be used to take opinion or sentiment towards an entity that is being discussed on social media such as Twitter. This study utilizes these data to determine public opinion or sentiment regarding public perceptions of the issue of rising electricity tariffs. Opinion taking is based on three classes namely positive, negative and neutral. Users often use non-standard word abbreviations or spelling, this can complicate the process and accuracy of classification results. In this study the authors apply text-preprocessing in handling these problems. For feature extraction, n-gram and classification methods are used using the Naive Bayes classifier. From the results of the research that has been done, the most negative sentiments are formed in response to the issue of the increase in basic electricity tariffs. In addition, from the results of testing with the method of cross validation and confusion matrix it is known that the accuracy of the naïve Bayes method reaches 89.67% before applying n-gram, and the accuracy rate increases 2.33% after applying n-gram characters to 92.00%. It is proven that the application of the n-gram extraction feature can increase the accuracy of the naïve Bayes method.

Abstract

The growth of technology in the last 3 years has been very rapid, as is the growth of smartphone use. This growth is directly proportional to the crime cases that occur, especially in Indonesia. There were a total of 12,835 case complaints from 2018 to 2020, and the most cases were online fraud cases with 7,560 reports related to fraud on cyber patrol sites. One of the crimes that often occurs is online fraud cases using fictitious transfer receipts. This crime was committed using one of the short messaging applications, namely Whatsapp. After the crime was successfully carried out, the perpetrator then deleted the evidence in the form of the conversation along with a photo of the proof of the transfer using one of the features on WhatsApp. Therefore, this study aims to obtain or acquire evidence on the Whatsapp application using the NIST (National Institute of Standards and Technology) method and applying the ELA (Error Level Analysis) technique to analyze evidence in the form of images obtained to strengthen the evidence in court. In facilitating the investigation process, a forensic tool is needed. The forensic tools used in this research are Magnet Axiom and ForensicallyBeta. The final result obtained is that Magnet Axiom managed to find some evidence, including conversation messages, victim contacts, call history, profile photos of the perpetrators, and pictures. With the help of ForensicallyBeta tools, the obtained receipt image can be analyzed and identified that there has been a modification to the receipt.

Abstract

Merapi Online Corporation is a company located in Yogyakarta which is engaged in internet access services. Merapi Online Corporation gives rewards by selecting the best employees based on criteria as a provision of the company. This study designed a system to determine the best employee selection using a Decision Support System (DSS) with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method has the principle chosen because it has the shortest distance to positive ideal solution and the farthest distance from the negative ideal solution from a geometric point of view using Euclidean distance to determine the relative closeness of choice with the best solution. The stages of this research are the collection of employee and criteria data, then weighting the criteria and assessment, after that the calculation uses the TOPSIS method, and the final step is the analysis of the calculation results. The criteria used in this study are attendance, years of service, permission, and discipline. Research has been successfully carried out on a sample of four employees for ease in presenting the data. The results of this study obtained the preferences of each employee, which is then ranked. The biggest preference value is chosen to be the best employee.
