Abstract

The accreditation system is a form of assessment (evaluation) of the quality and feasibility of higher education institutions or study programs carried out by independent organizations or bodies outside universities. The assessment is used as a quality benchmark for all study programs and higher education institutions, both from public and private universities that organize professional and academic programs. The better the value of accreditation will have an impact on the views of outsiders regarding the quality of the study program and higher education institution. However, the collection of data and information as well as filling out forms in the informatics study program still have many obstacles, such as the large number of data used as assessment criteria that requires a lot of time and effort. And also continuously accreditation that keeps repeating every few years is one of the problems faced in storing the accreditation data. ------------------------ Naskah ini telah di RETRACTED, silahkan baca https://journal.isas.or.id/index.php/JACOST/retraction.

Abstract

At this time the development of the era is much influenced by technology. This development has an impact on various aspects and fields in the expected life in the field of employment. Al-Azhar 32 Padang Islamic Elementary School is one of the private schools located in the city of Padang, West Sumatra. Al-Azhar schools have staff such as principals, teachers and administration so that the data entered is quite a lot.The staffing system at the Al-Azhar school is still manual by inputting it with excel. To take attendance at the employee using fingerprints and some use the attendance form. However, errors often occur during scanning because the scanner cannot detect someone's finger when the scanner is dirty. So that many employees update attendance by filling out the attendance update form. Given the problems above, it is possible to propose a mobile-based personnel application system. This staffing application has various features that can be used for taking attendance, leave forms, attendance history, school information, and employee profiles. This Android-based attendance can only be taken around the school or less than 20 meters from the school distance. To find out the distance between th0e user and the school, this attendance application uses the haversine algorithm to measure the distance between the user and the school

Abstract

The community considers that the services managed by the police seem less effective and efficient. Due to public complaints at this time, the community really needs information and fast service at the SPKT (Integrated Police Service Center). Services provided by SPKT, especially services for lost goods, for those who have lost their Vehicle Number Certificate (STNK), Car/Motorcycle, Driving License (SIM) for Car/Motorcycle, Identity Card (KTP), Family Card (KK), Automated Teller Machine (ATM) , Savings Books, Passports, Student Identity Cards (KTM), and others. At the Pekanbaru Police, when a complaint or complaint from the SPKT (Integrated Police Service Center) police unit is still manual where the making of the letter of loss is still using Microsoft Word by deleting and replacing the contents of the file. The purpose of this research is to assist the public in providing clear information and getting lost more easily and to facilitate the management of lost data from the community in order to determine the points where the loss of goods occurred. This system was built using the Protoyping Method, which is a method to get an overview of the system obtained from the user first, then it will be visited by the user so that it can be a reference for system development. The result of the user acceptance test (UAT) from the implementation of the program is that 100% functionality in the application is acceptable

Abstract

The problem that affects the character segmentation step is the step before character segmentation, namely preprocessing character segmentation or called preprocessing. This poses are strongly influenced by plate lighting conditions, shadows against plates, plate image impurities, plate image resolution, character cutting accuracy, and speed in recognizing characters. In general, identification consists of 3 stages, namely detection, segmentation and recognition. In this study, the use of the otsu method is expected to detect the region on the vehicle license plate, the region in question is the first region to show the regional code, the second region for the registration number and the third region for the sub-region code. In the process, the results of the vehicle number plate detection trial to get a segmentation of 3 regions of the vehicle number plate character did not get the expected results. The results trial obtained the identification of the entire character of the vehicle number plate so that the characters on the vehicle number plate could not be distinguished between the front letter, number, and the back letter. So to maximize the desired results so that getting 3 regions of the otsu method segmentation process needs to be improved using the mathematical morphology method. This mathematical morphology method serves to read the character value of each pixel in the digital image which produces a comparison between the pixels in the image, so morphology techniques are appropriate when used to perform image processing in obtaining the region of the vehicle number plate. From the improvement of the otsu method, the results of the trial were improved. Of the 100 data samples tested, 96 data samples passed and 4 sample data failed, the accuracy value using MSE measurements from the tested data samples received a very high increase, which was 96%.

Abstract

Currently, most of the patients seeking treatment at the hospital use the National Health Insurance (JKN) organized by the Healthcare and Social Security Agency (BPJS Kesehatan). In some hospitals, the figure is above 80%. Considering the very high number of BPJS Kesehatan participant seeking treatment at the hospital, a good data management method is needed, especially regarding the management of drug. Drug supply needs to be analyzed from time to time so that it can help predict future needs. An adequate supply of drugs and as needed is one of the things that affect service to patients. The availability of sufficient stock is expected to accelerate service to patients so that they do not have to wait long. Patients who are served quickly are expected to be satisfied. The impact of this patient satisfaction will increase the number of patient visits to the hospital. To support this, it is necessary to create a system that can estimate drug needs. The system can predict drug demand by using drug sales data to JKN participant patients for five years. Drug data used as research samples and then processed using an algorithm is the Naive Bayes Classifier. The Naive Bayes Classifier method is a method used to predict future opportunities using the basis of previous experience. A distinctive feature of this method is that it uses a very strong assumption of the independence of each event. While software testing uses the User Acceptance Test (UAT) model. Based on testing using this method, the system can be well received by users with a score of 78.64% (good).

Abstract

People with mental disorders are very much starting in Indonesia, the results of health research in 2015, 1,193,151 people or 0.467% of the population who suffer from mental disorders. This mental disorder disease should not be silenced anymore, must be followed up or minimized in order to improve health conditions in Indonesia. The poverty rate in Indonesia until now is still relatively high and makes it difficult for people to deal with mental disorders. As for minimizing the handling of this mental disorder, it is very suitable to build an expert system using the certainty factor method, which is a method that defines a measure of capacity for a fact or rule, in expressing the level of confidence of an expert on a problem that is being faced by a patient or sufferer and can also be used as a benchmark of the results of the diagnosis of a disease suffered. By making this expert system, it can be useful for many people and can know clearly about mental disorders from symptoms and solutions based on a website and using PHP programming with a MySQL database. The results of the study using the certainty factor method with tests that have been carried out by the user or users are that the type of mental disorder suffered is the type of schizophrenia with a 56% certainty rate.

Abstract

This study aims to design a fish trading application for SMEs and fishers in Batam. Batam is an area surrounded by the sea; most of the population makes a living as fishermen. The restrictions on community activities due to the Covid-19 pandemic have resulted in several weakening businesses where fishers and MSMEs have difficulty selling and distributing to consumers. The study took a case study on Tibelat Farm, an MSME, and anglers who cultivate fish and sell various consumption fish and ornamental fish. The application design uses the Laravel Framework with a UCD approach (User Centered Design), which involves the user in the business model to reach a broader market and complete available information. The results of the local community survey still have no confidence in online transactions, so in the design, they choose the pay-on-site or COD (Cash on Delivery) model. As an evaluation of the usability level using the SUS scale (System Usability Scale). The study results showed a SUS score of 57.58 which means that the application is functionally perfect and can be accepted by users.
