Abstract

Currently parking system that is running in Pt. Sanggraha Daksamitra still uses a conventional parking system. When the driver wants to do parking, driver first presses the analog button on the parking gate to get a parking ticket. Lack of maintenance on the parking gate causes vehicle jams in the parking entrance area. To minimize errors that occur, the fishbone diagram analysis method is used to analyze the problem. After the problem was found, a parking reservation was developed that used qr-code as a scanner identification in the parking system. The system produced in this study is expected to facilitate parking drivers who want to park their vehicles in the parking area of Pt. Sanggraha Daksamitra. The results of this system will be tested using blackbox testing.

Abstract

Cancer is one of the deadliest diseases in the world that needs to be handled as early as possible. One of the methods to detect the presence of cancer cells early on is by using microarray data. Microarray data can store human gene expression and use it to classify cancer cells. But one of the challenges of using microarray is its vast number of features, not proportional to its small number of samples. To resolve that problem, dimensionality reduction is needed to reduce the number of features stored in microarray data. Binary Particle Swarm Optimization (BPSO) is one of the methods to reduce dimensionality of microarray data that can increase classification performance. Although when combined with Backpropagation, BPSO still shows a relatively low performance. In this research, Modified Backpropagation with Conjugate Gradient is used to classify data that has been reduced with BPSO. The average accuracy result of BPSO+CGBP is 86.1%, giving it an improvement compared to BPSO+BP which averaged to 80.8%.

Abstract

Currently, the sales system is overgrowing. The concept of selling that was done manually (which is still less than optimal) becomes electronic (e-commerce). System development requires a digital platform. This platform must be able to carry out all activities that were carried out before (manually), such as collecting documents, recording transactions, and reporting. Besides, the e-commerce platform can provide support and increased performance in the sales process, both in checking stock items, transaction reports, and services. Besides, this optimization can provide services precisely and quickly to consumers. A management information system concept is needed to carry out e-commerce and services with integrated data and be stored in its development database. This prototype concept requires a method for website development. The method used is a waterfall. Website design uses the Hypertext PreProcessor (PHP) programming language and MySQL database. The design model uses two concepts: entity-relationship diagrams (ERD) and data flow diagrams (DFD). The result is a website and e-commerce services that can be accepted by users and e-commerce organizers with tests that have been carried out. System testing uses Blackbox and Whitebox testing, each of which results can be used to implement e-commerce sites and services. The website can assist officers in service and e-commerce and make it easier for officers to determine the target and service status.

Abstract

Recognition and mastery of the hijaiyah letters which are the basis for reading and studying the Holy Qur'an from an early age is very important, because if at the time of reading the hijaiyah letters you are accustomed to the wrong words it will cause different meanings so that we are required to read properly and correctly. The method in learning hijaiyah letters is usually given by traditional (conventional) reciting teachers or people often call it the sequential method. With this kind of teaching, children tend to be passive in accepting their teaching lessons, because the Koran teacher explains the children in learning to read hijaiyah letters orally, in writing and in body language. The application of recognizing hijaiyah letters is very effective and easy to use for students of paud al fina in recognizing and writing hijaiyah letters because the design of the learning aid program to read hijaiyah letters is a method in the form of visualization in the form of images, text and sound. To implement this method, the author uses Android Studio programming which acts as a tool (programming system) used to build an application, this application program is expected to generate interest for early childhood or adults who want to learn how to learn to read hijaiyah letters properly and correctly. accommodated.

Abstract

Kelurahan 16 Ulu is one of the areas in the city of Palembang which has an area of 475 Ha and consists of several RT. Citizen data collection is the main task of a RT head. The process of managing citizen data by the head of the RT at Kelurahan 16 ulu is still using manualmethod so to get and search information about citizen spread point and data mapping cost a lot of time cause the data still in family card, and the data not yet in mapping state. To solve this problem, it needs visually show the mapping based on Geographic Information System (GIS). GIS is able to manage data that have spatial references for purposes related to mapping and planning. The resulting mapping visualization is in the form of E-government based on GIS. So that it can help to find out the citizen spread point and improve effectiveness and performance in service to the citizen.

Abstract

The lecture schedule is a problem that belongs to the NP-Hard problem and multi-objective problem because it has several variables that affect the preparation of the schedule and has limitations that must be met. One solution that has been found is using a Genetic Algorithm (GA). GA has been proven to be able to provide a schedule that can meet limitations in scheduling. Besides, it also found a new concept of thought from GA, namely the Fluid Genetic Algorithm (FGA). The most visible difference between FGA and GA is that there is no mutation process in each iteration. FGA has a new stage, namely individual born and new constants, namely global learning rate, individual learning rate, and diversity rate. This concept of thinking was tested in previous studies and found that FGA is superior to GA for the problem of finding the optimum value of a predetermined function, but this function is not included in the multi-objective problem. In this study, the testing and comparison of FGA and GA were conducted for the problem of scheduling lectures at STMIK XYZ. Based on the results obtained, FGA can produce a schedule without any hard constraint violations. FGA can be used to solve multi-objective problems. FGA has a smaller number of generations than GA. However, overall GA is superior in producing schedules without any problems.

Abstract

MAN 1 Inhil is a school that applies ministerial regulations to determine the direction of student majors at the beginning of entry, namely in class X. Determination of majors is done by considering several indicators, namely the results of academic tests, interviews, and student interest. The calculation in determining this course is very simple, namely by adding up the values of each indicator and dividing them together so that an average value is obtained. If the value is fulfilled then the student is grouped based on their interests. This can lead to errors in decision making by the school because it can be subjective because it prioritizes student interests. Therefore we need methods and algorithms to help make decisions well, the decision tree method. One algorithm that can be used is CART algorithm to classify majors with three indicators, namely Natural Sciences, Social Sciences and Religion. The results of this study indicate that the CART algorithm is able to predict correctly, from 360 data classified using the CART algorithm, it can be concluded that 71 data majoring in religion and correctly classified by CART. 144 data majoring in Natural Sciences, 119 data correctly classified and 24 data classified as IPS, and 1 data classified as religion. Of 146 data majoring in social studies, 129 were classified correctly, 16 data were classified as natural sciences. Therefore it can be concluded that CART algorithm has an 80% accuracy so that it can be used in decision making

Abstract

Al-Qur'an has a lot of content, so the system of searching for verses of the Al-Qur’an is needed because if it is done manually it will be difficult. One of the search systems for the verses of the Al-Qur'an in accordance with Indonesia’s pronunciation is Lafzi. The Lafzi system can search for verse fragments using keywords in Latin characters. Lafzi has been developed into Lafzi +, wherein the Lafzi + system can be used to search verses of the Al-Qur’an with different sounds on stop signs. However, the Lafzi+ can only overcome the difference in the sound of the stop sign and cannot be applied throughout Al-Qur’an. Based on these problems, the system needs to be developed to overcome the differences in sound in the middle of the verse and can be applied throughout the Al-Qur’an. The method used in the process of searching for the verse is the N-gram method. The N-gram used in this research is trigram. The process flow of this system is first normalized in the phonetic coding process after normalized then tokenization of trigrams and then trigrams are matched between the query and the corpus and entered into the ranking process to get an output candidate. In the making process, the LIS (Longest Increasing Subsequence) method is used to get an orderly and strict trigram sequence. The highest order score will be the top output. The results of this study obtained a recall value of 100% and MAP of 87%.
