CONSUMER INFORMATION SYSTEM IN WEB-BASED COOPERATIVES: CASE STUDY OF DIRA JAYA SINAR RESKI COOPERATIVE

ABSTRACT


Introduction
In this world full of progress, globalization demands to continue to innovate and be creative.in this case, looking for and making contemporary innovations to balance the process of accelerating globalization in the field of information technology (IT) with the competencies possessed can be achieved optimally in everyday life.
A website is a collection of pages that contain specific information and are easily accessible to anyone, anytime, and anywhere via the Internet.Website is also a method to display content and information in the form of text, images, audio and video, and can connect one document with another document that can be accessed through a browser [1].
There are many advantages to providing information on the website apart from the media.The benefits of this website include: the website functions as a company brand builder, the website functions as an advertising medium, the website functions as a means of customer service, and the website functions as a place for criticism and input.Using the website offers many advantages [2].However, there are still many who have not utilized the web as an effective source of information, especially for business development.Some large companies today maximize the website as a tool to support business information.With the existence of social media that allows promoting business, the website is also needed as one of the media and as a profile of a company and can be trusted by the public.
As one of the pillars of the Indonesian economy, cooperatives are based on the principle of kinship.That's why cooperatives have been known for a long time by people in Indonesia in helping the economy, especially for the lower class.Since then, cooperatives have grown and are in demand by many people [3].Cooperatives within the economic system are milestones for society.Cooperatives in Indonesia do not yet have the ability to carry out their role effectively and strongly.This is because cooperatives still face structural obstacles in managing production copyrights, especially capital.However, it still requires greater attention by the government so that the existence of cooperatives in Indonesia can indeed be an economic milestone for the community as stated in the 1945 Constitution [4].
Dira Jaya Sinar Reski Cooperative is a consumer cooperative located on Jln.Mappajalling Dg.Kawang, Pattallassang District, Takalar Regency.This cooperative has a number of customers who have made many deposit and loan transactions, not a few employees who have difficulty in the data collection process because this cooperative has not met the standards of computerized technology.However, employees never experience problems in fulfilling information to customer members, for example in terms of notifying loans or remaining consumer loans using methods by making loan cards filled in according to the customer's payment date.
Based on observations made on Thursday, April 6, 2023 through interviews with teller staff at the Dira Jaya Sinar Reski cooperative, it was found that the collection and recording of consumer information is still manual, namely bookkeeping that is not stored in the database.This can cause many shortcomings, for example the search for information takes a long time, as well as inefficient time when recording and storing information because you have to write in several books as proof of the recording.
The problem that occurs in the Dira Jaya Sinar Reski cooperative is that there are often difficulties in carrying out the data collection process that still uses manual methods such as writing in a ledger.This results in the data collection process takes a long time and data is less secure because it is still stored in books, when managing customer data such as recording final transactions, the data needed is incomplete, even the data is often tucked away and prone to damage or loss because it does not have a backup.
Based on the existing problems, the author wants to create a web-based consumer information system at the Dira Jaya Sinar Reski cooperative tailored to the needs of the cooperative with the title of the thesis "Consumer Information System at the Web-Based Dira Jaya Sinar Reski Cooperative" which is expected to help and facilitate the process of managing data at the Dira Jaya Sinar Reski cooperative.

a. Types of Research
This research uses research and development methods or also called R&D (research and development) with a prototype model.Research and development methods are research methods used to produce certain products and test the effectiveness of those products.This prototype model is a software development method that is suitable for the development process of this information system, this method is also structured and if in the stages of work.The stages of the prototype model consist of Requirements Collection, Prototyping, Prototyping Evaluation, System Coding, System Testing, System Evaluation, and System Use [5].

b. Development Procedure 1) Collection of needs
The software format is defined jointly by the developer and the client, as well as when identifying needs and the system being built [5].

2) Prototyping
This stage is the stage of making temporary plans with a focus on customer or client desires such as making inputs and outputs needed [5].3) Prototype Evaluation At this stage, the client will check the prototype that has been built with the aim of ensuring the system that has been designed is in accordance with the goals and needs of the client or not [5].If the prototype built is not appropriate, corrections and improvements will be made again at the previous stage.

4) System Coding
Prototypes that have been approved in the previous stage will begin to be made in the form of code or coding at this stage, by translating them into programming languages.

5) System Testing
Systems that have been converted into programming languages and have become software will be tested first to determine whether the software can be used or not.The tests carried out have the aim of ensuring that the errors produced by the system are kept to a minimum.

6) System Evaluation
The evaluation stage is the user trial stage when using the system.This test aims to measure the level of user satisfaction with the system.

7) System Usage
Systems that have been built and successfully passed the system evaluation stage can already be used.

c. Data Collection Techniques 1) Interview
The interview was used to obtain in-depth information related to research through questions and answers with the cooperative leader Dira Jaya Sinar Reski with the aim of collecting data on how the data capture system in the cooperative.

2) Observation
The observation method is to make direct observations to the Dira Jaya Sinar Reski Consumer Cooperative.Observations are made so that researchers can understand how the data capture system exists in cooperatives so that researchers get a comprehensive view of the real problem so that the data obtained is more accurate and objective.

3) Questionnaire
This questionnaire method is used to collect data using a list of statements that researchers have used to determine the feasibility of the software.The questionnaire is used to determine the feasibility of consumer information system software in cooperatives in terms of functional suitability and usability.

d. Research Instruments 1) Instrumen Functional Suitability
Testing on aspects of functional suitability, using a research instrument in the form of a testcase with the Guttman scale.The Guttman scale is used to get an unequivocal answer to a problem that wants to be stated.In the answer of each item the instrument uses an unequivocal answer, namely "Yes" or "No" [6].

2) Instrumen Usability
Usability aspect testing using the USE Questionnaire [6] there are 14 questions divided into 4 criteria, namely usefulness, easy of use, easy of learning, and satisfaction.

e. Data Analysis Techniques 1) Analysis of Functional Suitability Aspect Testing
Functional suitability testing is carried out by testing each software function by programming experts (programmers/ developers).The scale used in testing functional suitability factors is the Guttman scale.Answers can be made in the form of a checklist with the highest score (yes) valued at 1 and the lowest score (no) valued at 0. Meanwhile, to determine the level of software feasibility in terms of functional suitability, researchers use the interpretation of standards set by ISO 25010 [6].To determine the value of functional suitability, the equation formula is used: 2) Usability Aspect Testing Analysis Usability factor testing is tested using questionnaires distributed to users and respondents.The scale used in usability factor testing uses the Likert scale so that users can later infer the functionality of the software.The Likert scale is used to measure a person's attitudes, opinions and perceptions [7].
This questionnaire was distributed to 15 respondents by asking 14 questions through questionnaires so as to obtain results that will be processed using descriptive statistical analysis.This instrument consists of 14 questions tested to 15 people, 8 cooperative employees and 7 customers appointed as respondents in this test.The score criteria on the Likert scale can be seen in Table 2.

Answer Score
Totally Agree (SS) 5

Disagree (TS) 2
Strongly Disagree (STS) 1 Hal. 64 Usability testing uses descriptive analysis techniques where analysis is needed in order to explain a data by describing it, so that conclusions are obtained from a group of data.The score is calculated using a conversion formula to percentage score to find criteria for interpretation of the score of the usability test results.Here is the formula for converting to percentage scores [7].
The results of those score percentages are then compared to a table of score interpretation criteria.The score interpretation criteria can be seen in Table 3. 0 -20 Very Unworthy

3) Realibility Aspect Testing Analysis
The purpose of reliability testing is to test the reliability or trustworthiness of a system.This test will be carried out using web server stress tools, testing system performance while it is running [8].Testing web server stress tools is carried out by three methods, namely click test method, time test and run test method.

4) Performance Efficiency Aspect Testing Analysis
Performance efficiency testing is intended to test the level of performance efficiency of the developed application.Performance efficiency testing is carried out with the GTMetrix software application, by testing the efficiency of system performance while working.GTMetrix Report results must meet a load time of less than 10 seconds.So that the testing of performance efficiency characteristics is said to be high [6].

5) Maintainability Aspect Testing Analysis
Testing on maintainability aspects using measures tested by researchers directly in the field operationally, in accordance with the test instruments mentioned by Land, this test includes 3 aspects, namely instrumentation, consistency and simplicity.

Instrumentation
There is a warning from the system if something goes wrong along with error identification Consistency Use of one paada plan model of the entire system plan Simplicity Ease of system management, repair, and development

6) Portability Aspect Testing Analysis
Portability testing is intended to determine the ability of information systems to function in different environments.Tests were conducted on different devices (mobile phones, computers, and laptops).

7) Compatability Aspect Testing Analysis
Compatibility testing is intended to determine the ability of information systems to work in different environments.It has been tested with various programs, namely browsers (Ferifox Mozilla, Google Chrome, Opera, etc.).The compatibility aspect is said to be high when it can work in 90% different environments.

8) Security Aspect Testing Analysis
Security testing is carried out to determine the security of the information system that has been created, if when testing the system has good security, then the system made has met the security aspect.

a. Needs Collection
At the data collection stage, it is carried out by interviewing with cooperative employees as admins.The interview aims to collect customer data, deposits, and loans at the cooperative, and to find out the web-based information system of the Dira Jaya Sinar Reski cooperative that has been running.The results of this stage are as follows: 1) The Dira Jaya Sinar Reski Cooperative needs an information system that can be used to make the process of managing customer data more efficient.2) Cooperatives also need a system that can simplify the process of data disclosure so that reporting to leaders is more structured.3) Actors or system users consist of users who will view, input data, apply for deposits and loans, and download the results of loan and deposit data capture.

b. Building a Prototype
Based on the results of the requirement collection, the next step is to build a prototype.This step is done by making a temporary draft.The design is in the form of context diagrams, Data Flow Diagrams (DFDs), activity diagrams and system testing described in the previous chapter.

c. Prototype Evaluation
This evaluation was carried out by employees of the Dira Jaya Sinar Reski Cooperative, whether the prototype that had been built was as desired or not.If it is appropriate, then the next step will be taken.But if not, the prototype is revised by repeating the previous steps.
Based on the results of the first evaluation of the prototype by Dira Jaya Sinar Reski Cooperative employees, the system was asked to change, and add several features, namely: 1) Added installment feature for admin users to make it easier for customers to know the amount to be paid each month.
2) Increasing consumer access so that customers can see their savings and loans.
3) Changes to the login interface to make it more attractive.

d. System Coding
At this stage the agreed system design is translated into a web programming language.The web programming language used is Personal Home Page (PHP) and database management system using MySQL.The results of system coding are shown in the following sections:

e. Application Testing 1) Functional Suitability Testing
Functional suitability testing is a test conducted to determine the feasibility of a web-based consumer information system at the Dira Jaya Sinar Reski cooperative that has been developed by researchers.This test was conducted by 2 experts.The answer to each question item uses the Guttman scale.The results of functional suitability testing can be seen in Table 4.
Hal. 67 To determine the value of functional suitability used equations [6]: X = 1 -0K, X = 1 Because A = 0 and B = 29 then worth 1.The test results have a maximum value of 1 or 100%, then the software has met the functional suitability aspect with a very good level.

2) Usability Testing
Usability testing was carried out by conducting direct trials to users consisting of 15 people, 8 cooperative employees and 7 customers appointed as respondents in this test.The questionnaire given to users consists of 4 aspects with a total of 14 questions.The assessment results of the user feedback testing can be seen in Table 5.Based on the usability aspect data that has been obtained, then the number of scores from all aspects will be applied using descriptive statistical analysis on the number of scores obtained from usability testing and obtained the following results: Based on the results of usability measurement is carried out to calculate the percentage of answers from a number of respondents.The observed score was obtained from the total score of all answers from 15 respondents, which was 978, while the expected score was obtained from the maximum number of scale scores multiplied by the number of questions then multiplied by the number of respondents, which was 1050.After knowing the results of descriptive statistical analysis, the most measurement results showed the "Decent Enough" category with 8 users with an average relative frequency of 53.33 and an average cumulative frequency of 93.33.

3) Reliability Testing
System reliability testing uses web server stress tools to simulate large system visitors.If the system passes this test without interruption, then the application can be trusted.While testing with this program there are three tests, namely click testing, time testing, and running tests [8].

4) Performance Efficiency Testing
Performance efficiency testing is carried out using help from the GTMetrix website [6] where testing is done by entering the link to the tested page then GTMetrix will check and produce a performance score, structure, and fully loaded time or the time the page is fully loaded.

Discussion
The development of a consumer information system at the web-based Dira Jaya Sinar Reski cooperative is designed to make it easier to manage data so that it is neatly arranged and structured, this system is managed by the cooperative admin and can be accessed by customers.This information system is web-based so that it can be accessed by different platforms.
System developers must meet good quality criteria, therefore guidelines are applied to system development [10].This is so that the application development process can be accounted for because it has been carried out based on agreed standard procedures.The system is created using a prototyping development model.Prototyping generally includes gathering needs, building prototypes, evaluating prototypes, coding systems, testing systems, evaluating systems, and using systems [5].
The system is built using PHP (Personal Home Page) programming language [11] and management of its system database using MySQL [12].The process of developing information systems using the Laravel framework and the help of web server software, namely apache in the XAMPP application [13].This aims to make it easier for researchers to create systems.Based on the study, researchers use the type of R&D research (research and development) [14] with data collection methods using interview, observation, and questionnaire methods and using test methods based on ISO/IEC 25010 standards [7].
This study uses 8 aspects of ISO / IEC 25010 feasibility testing methods, namely functional suitability, usability, realibility, performance efficiency, maintainability, portability, compatability and security [7].Testing of functional suitability aspects was carried out by 2 system experts and it was found that this application was in the category of very good for use [6].Reliability aspect testing meets test standards [8].Performance efficiency aspect testing was carried out using GTMetrix and obtained results of 93% meeting the grade A criteria [6], Usability aspect testing was carried out by employees and customers of the Dira Jaya Sinar Reski cooperative using questionnaires distributed to 15 respondents with a feasibility percentage of 87.9% and were in the "decent enough" category.100% maintainability testing is in the "very feasible" category.Testing the portability aspect is carried out by running the application using several PC and mobile devices in various versions.Compatibility aspect testing is done by running the application in several browsers.And testing the security aspect was carried out using the Quteera web and showed the results that this information system is safe to use [9].
Based on the results of the research of consumer information systems at the web-based Dira Jaya Sinar Reski cooperative, after validation and testing based on ISO/IEC 25010 quality standards using 8 test aspects, it can be concluded that the consumer information system at the web-based Dira Jaya Sinar Reski cooperative is feasible to use.
