Decision Support System for Selection of Quality Palm Seeds with the Analytical Hierarchy Process Method

At PT. Gersindo, which is located in West Pasaman Regency, is a factory company that processes palm fruit into semi-finished oil or often called CPO (Crude Palm Oil). The main part that is managed in oil palm is the fruit, the fruit of the oil palm produces crude oil. PT. Gersindo is currently still using the manual method in determining the quality of the oil palm kernels, so that problems arise in the selection of the oil palm kernels at PT. Gersindo. At the factory PT. Gersindo in selecting quality palm kernels can be solved by developing an application in a decision support system. A decision support system is a system that is able to solve problems efficiently and effectively, which aims to help make decisions by choosing various alternative decisions. One technique that can be applied in developing a decision support system is to use the AHP ( Analytical Hierarchy Process ) method. The AHP method is a method in a decision support system for solving a very complex and unstructured problem into several component parts in a hierarchical arrangement by giving subjective values. The essence of the AHP method is to determine the weight value for each criterion. The results of this study can be determined Consistency Ratio (CR) is 0.0705 . And CR is less than 0.1 , then the matrix is declared consistent, so it is very effective and efficient in making decisions on selecting quality palm kernels.


Introduction
The role of computers today is very large in all fields, be it business, entertainment, to the military. With a computer, it can simplify and speed up a job, and carry out complex processes. Changes and developments in technology and advanced information systems are increasingly needed to help complete human work in various fields. A company or agency should have an information system design that suits their needs, so that it can produce high-value technology and can be used in making decisions.
At PT. Gersindo, which is located in West Pasaman Regency, is a factory company that processes palm fruit into semi-finished oil or often called CPO (Crude Palm Oil). The main part that is managed in oil palm is the fruit, the fruit from oil palm produces crude oil and the rest of the processing is used as a mixture of animal feed [ 1]. PT. Gersindo is currently still using the manual method in determining the quality of the oil palm kernels, so that problems arise in the selection of the oil palm kernels at PT. Gersindo.
Factory PT. Gersindo in selecting quality palm kernels can be solved by developing an application in a decision support system. A decision support system is a system that is able to solve problems efficiently and effectively, which aims to make decisions by choosing various alternative decisions [2].
Decision Support System (DSS) is a system that can provide problem solving, communicate for solving certain problems with structured or unstructured. SPK is designed to be used and operated easily by people who only have basic computer operating skills. SPK is made by implementing high competency adaptation so that it can be used as an alternative in making a decision [3]. SPK as a system that supports a person or a small group of managers who work as a problem solving team (decision making team), to make decisions on semi-structured problems by providing specific information. Decision support systems will also facilitate the decision-making process and provide solutions to existing problems [ 4]. DSS is designed to support all stages of decision-making starting from problem identification, selecting data, determining the approach used in the decision-making process and evaluating alternative selection activities [5].
One technique that can be applied in developing a decision support system is to use the AHP ( Analytical Hierarchy Process ) method. The AHP method is a method in a decision support system for solving a very complex and unstructured problem into several component parts in a hierarchical arrangement by giving subjective values. The essence of the AHP method is to determine the weight value for each criterion [6].
-making method was first developed in 1980, by Thomas L. Saatya in his book Analytical Hierarchy Process. The Analytical Hierarchy Process (AHP) is a decision-making process using pairwise comporisons to explain evaluation factors and weight factors in multi-factor conditions [7].
Previously, research on decision support systems had been carried out under the title Application of Decision Support Systems for Acceptance of School Operational Assistance Funds for SMA N 1 Students. The applications designed and implemented are supported by the TOPSIS method, using the waterfall development method and implemented with flowcharts, context diagrams, data. Flow Diagrams, Entity Relationship Diagrams, Table Relations, Table  Specifications [8]. Decision Support System for Selection of Computer Service Places in Bandar Lampung City Using the AHP Method, Extreme programming is used as a system development method including planning, design, coding and testing which will be tested by functionality testing (Black Box) and system feasibility testing. The results showed that the best alternative was Asacom with a total score of 7.5204 [9]. Application of the Exponential Comparison Method (Mpe) in the Decision Support System for Outstanding Student Scholarship Recipients at Xyz Vocational High School. This research produced a decision support system to determine outstanding student scholarship recipients with criteria of achievement, discipline, attendance by applying the MPE method [10]. Web-Based Information System for Management of Recipients of Zakat, Infaq and Alms Funds. In this system there is a system for inputting data, searching for data, editing data, updating data and preparing reports that make it easier for users to search for data, change data and update the desired data [11]. As well as Designing an Online-Based Smart Indonesia Scholarship Program (PIP) Information System ( Case Study: SMA N 1 Kota Bumi), this information system can be used to register for scholarships online, manage information content, and view scholarship selection results [12]. a decision support system using the AHP method in product selection obtains results to assist in decision making based on the output results provided through the use of predetermined criteria and sub-criteria [13]

Research methodology
To assist in the preparation of this research, it is necessary to have a framework with clear stages. This framework is the steps that will be taken in solving the problems to be discussed, can be seen in Figure 1 below: Based on the research stages in Figure 1, each stage can be explained in detail as follows:

Preliminary Research
Preliminary research is the process of approaching the research object. The purpose of studying the literature in this research is to strengthen the theory and methods used to solve existing problems as a theoretical basis for conducting studies.

Data collection
For data collection, the authors obtained data from various sources, such as this research, obtained from articles, obtained from other references , and the authors conducted interviews directly with the managers at the PT factory. Gersindo. The author records some important information related to the research being carried out.

Analysis a. Data analysis
This analysis is carried out to limit the object to be studied so that it becomes information that is more systematic and easy to understand. The data analysis stage is the most important stage in developing a system. The data obtained is in the form of interviews with the Manager at the PT. Gersindo.

c. System analysis A very important stage if there is an error at this stage it will cause an error at the next stage. This analysis is carried out to find out what is needed in system development. So that it can produce an effective and efficient system in its implementation later. Where the program will be created using the PHP programming language and MySQL database.

Design
At this stage the authors design the system to be developed. The author will analyze the program that is currently running and design the application that is being developed.

Implementation
System implementation is the stage of laying the system so that it is ready to operate. Implementation aims to confirm design modules, so users can provide input to system development. At this stage the system design is carried out using the PHP and MySQL programming languages.

Testing
Testing is one of the important things in the production process to find out whether the product that has been produced is well controlled or not. After the coding process is complete, a testing process will be carried out on the resulting application to find out whether the designed application is running correctly and in accordance with the design being carried out.

Analytical Hierarchy Process Method
The analysis of the weighting of the criterion values in the AHP (Analitycal Hierarchy Process) method is by means of create a pairwise comparison matrix that describes the relative contribution. Based on the data that has been obtained, the criteria for selecting highquality oil palm kernels are as follows: Doing the weighting, we get a pairwise comparison matrix which can be seen in Table 1  Weighting analysis converts the values in the pairwise comparison matrices into decimal numbers to get the Total matrix ( Priority Vector ). Then normalize the values on the matrix, which can be seen in Table 2 below: The results of carrying out the normalization calculation phase can be seen in Table 3 below: Results normalization And Eigen Vector ( EVs) or value the average matrix can be seen in Table 4 below: multiply priority Vector with Eigen Vector Which has got previously. And result can seen Table 5 following:
