Abstract

Students in grades 4-5 Elementary School Al-Ikhlas need an Android-based application to find the meaning of the Qur'anic verses to help and make it easier for students to find the meaning of the verses of the Qur'an and do the tasks given by Islamic Religion Teachers. Making the application's search for meaning verses of Qur'an using methods matching string (string matching) that is implemented in the search process said. String matching will perform the search process for a string or several strings found in a text or string. The algorithm used in string matching is berry ravindran, this algorithm has 2 phases, namely the preprocessing phase and the search phase. The phase preprocessing serves to create a shift value that will be used in the search phase. The value of the search phase is obtained from the rules of the algorithm. The Algorithm is berry ravindran implemented to perform analysis string matching in the application of finding the meaning of the verses of the Qur'an. This application to search for the meaning of the verses of the Qur'an can search for the meaning of the verses of the Qur'an by using voice, it is hoped that this voice search feature can facilitate the search for the meaning of the verses of the Qur'an. Speech recognition is implemented using one of the Google Cloud Platforms, namely the Google Speech API to detect spoken words when searching, so that it can make it easier for users to search for the meaning of the verses of the Qur'an. It is hoped that this application can be used as a source of knowledge and useful for grade 4-5 students at Elementary School Al-Ikhlas so that they are more diligent in reading the Qur'an and finding out the meaning of the verse, in order to guide them to the right path to the path that is pleasing to Allah.

Abstract

The choice of shuttlecock is very important in playing badminton. In determining the shuttlecock to play badminton generally only involves reasoning skills or choosing randomly. Determination of shutllecock recommendations is considered important because through this activity the quality of each brand can be known. The method used in the shuttlecock selection decision support system is using the Simple Additive Weight (SAW) and Analytic Hierarchy Process (AHP) methods which aim to compare SAW and AHP. The criteria used are feather material, cork material, speed, level of usage, and price. The decision support system is designed with the PHP programming language and MySQL database to test and determine the ranking of several available alternatives. Then the results obtained from the assessment using the SAW method as the main priority of Yonex Shuttlecock Aerosena 50 (code: S3) as the best shuttlecock, while with the AHP method the main priority was Shuttlecock Victore Master Ace (code: S13) as the best shuttlecock. The ranking of each method will be used as a consideration for badminton players in choosing the appropriate shuttlecock for use

Abstract

Advances in technology, information and technology at this time are growing rapidly, a lot of human work is facilitated by technology. Technology has also developed in investment instruments, especially in stock investments. Previously, when there was no technology, it would be very difficult to predict the stock price of state-owned banks in the future for ordinary people who do not understand fundamental or technical analysis. However, with technology, especially in the field of Deep Learning, it will be very possible to predict future stock prices without having to understand fundamental or technical analysis. In this study, stock price predictions of state-owned banks for the next 30 days were made using the Gated Recurrent Unit (GRU) model on stocks of state-owned banks in Indonesia, namely BRI, BNI, BTPN, and Mandiri bank shares. The data used uses historical close price data on the stock for 5 years with a total of 1260 data. From the results of the research for test data, the smallest RMSE value was found in BTPN bank shares of 23,91164 followed by BRI bank shares of 264,1475, BNI bank of 427,7984 and the largest RMSE value in BMRI bank shares amounting to 907,4804

Abstract

Research using the electrocoagulation method has been carried out to determine the results of the sample test results for BOD and COD parameters in palm oil mill effluent. The electrodes used n this method are aluminium electrodes with varying adapter voltages of 6, 9, and 12 Volts. Palm oil liquid waste used comes from PTPN IV Adolina Perbaungan. The results of the study showed that before the electrocoagulation method the BOD value obtained was 243 mg/l, while after the electrocoagulation method the best results were obtained at a voltage of 12 Volt with a value of 52,5 mg/l. The value obtained before the electorocoagulation method was carried out on the COD parameter was 649 mg/l and after the electrocoagulation method the best results were obtained at a voltage of 12 Volt, which was 110 mg/l. This shows that the parameter values of BOD and COD in processed waste have decreased and meet the wastewater quality standards for the palm oil industry, namelyb 100 mg/l and 350 mg/l. The higher the value of the applied voltage, the more optimal the levels of BOD and COD.

Abstract

Geographic Information System is a system created based on the geographic mapping of the earth. This system can provide information about the location of the area or the location of places on the earth's surface, provide information about a location and information about the shortest path from one location to another. The city of Padang Sidempuan currently has many tourist attractions that have a beauty that is not far from other cities, such as Tor Simarsayang, Silima-Lima Waterfall, Aek Sabaon and others. However, currently there is no application that can make it easier for tourists to get information to get to the tourist attractions in question. The Floyd-Warshall algorithm is a method that performs problem solving by looking at the solution that will be obtained as an interrelated decision and will choose the shortest path from several alternative paths that have been generated from the calculation process. In this study using the waterfall research method, android programming language and MySQL database with data as much as 10 tourism points. The final results were tested using the black box testing method, obtained an average accuracy of 90% of the results of the shortest distance from each point and the system can display features, such as tourist data features, tourist facilities, cost estimates, tourist pictures and opening times of the tourist attractions

Abstract

School Operational Assistance (BOS) has an important contribution to increase access to education in Indonesia. Deli Serdang Regency is a district that has a large number of residents, schools and students with a large number of schools and students, so sometimes the budget funds for BOS funds are not sufficient to provide all schools with the total number of students listed in the madrasah emission data. With the lack of government budget for BOS funds, a cut in the distribution of BOS funds was carried out in each school which was usually done manually by only looking at the number of students registered in the EMI data and determining the percentage of distribution of BOS funds to each school regardless of the needs that must be met at the school. In this final project, the researcher makes a data mining system for determining the amount of distribution of BOS funds in Deli Serdang Regency, this system is built using the Naive Bayes algorithm as a means of calculating BOS funds according to predetermined criteria, this system uses the PHP programming language using the CodeIgniter framework and MySQL as database method used in this system is waterfall. This system was built with the aim of making it easier to distribute and so that the distribution of BOS funds is right on target to schools in need.

Abstract

Mudharabah financing is a product that is in demand by the public, especially for those who want to develop their business but do not have capital. Meanwhile, murabahah financing is a product that offers buying and selling between BMT Tebing Tinggi and members. BMT Tebing Tinggi will purchase or order goods according to the request of members, then sell them to members at the purchase price plus the agreed BMT Tebing Tinggi profit. Data processing activities on this financing product are still carried out using hand or written media, services are hampered so that members have to wait a long time. Based on this background, an Android-based mudharabah and murabahah financing application was made. In making this application, researchers used qualitative methods to analyze data using Unified Modeling Language (UML) tools. By using kodular tools, Java as the programming language and MySQL as the database. This financing application produces a system that facilitates activities that occur at BMT Tebing Tinggi such  as member registration, savings submissions, financing applications and installment payments, as well as simplifying data processing such as member data, savings, financing, and installments.

Abstract

The need for an electrical energy source is currently a very necessary thing, therefore researchers conducted experiments on the use of pineapple peel (ananas  comosus) extract as an electrolyte solution with a variety of electrodes. This research was conducted with the aim of generating voltage, electric current, and strength values. The measure of the holding capacity of the solution used were 50 ml, 100 ml, 150 ml, 200 ml, and 250 ml. The electrodes to be used are in the form of copper-zinc, copper-iron, and copper-aluminum pairs with each plate measurement of 4 cm × 7 cm, thickness of 0.2 mm. To determine the magnitude of the value of the voltage and current, a resistance is given in the form of an LED lamp. Based on the results of the research the pH measurement of the solution was 3.9. The test results obtained by the pair of Cu:Zn plates are the best compared to other pairs of plates, namely by producing a voltage of 1.59 Volts, a current of 0.28 mA, and an strength values of 0.44 mW with a volume of 250 ml. This is due to the influence of the volume of the solution and the electrodes used, that the more plates submerged in the solution, the greater the energy produced.
