MEASUREMENT OF ALMAMATER SUIT SUPPLY CHAIN PERFORMANCE IN SACIKA COOPERATIVE USING SCOR

: SACIKA Cooperative, as a student cooperative at the Telkom Institute of Technology Purwokerto, provides almamater suit procurement services. Currently, the process of procuring and ordering almamater suits is faced with several obstacles, which results in students as customers feeling disadvantaged during the ordering process. Therefore, it is necessary to evaluate the performance of the supply chain at the SACIKA Cooperative in order to improve efficiency and suitability in the procurement of alma mater suits. This study aims to assess the performance of the alma mater suit supply chain at the SACIKA Cooperative using the SCOR Matrix. This type of research is descriptive quantitative, with data collection conducted through interviews and observations. Supply chain performance measurement is carried out using four attributes and matrices, namely Reliability with Perfect Order Fulfillment (POF), Responsiveness with Order Fulfillment Cycle Time (OFCT) Matrix, Agility with Cost of Goods Sold (COGS), and Assets with Cash-to-Cash Cycle Time (CTCCT) Matrix. The results showed the performance value of each matrix, namely POF of 96.47%, OFCT 1 day, COGS 92.94%, and CTCCT 8 days.


INTRODUCTION
Satria cipta karya cooperative or known as Sacika cooperative is a student cooperative located at Telkom Institute of Technology Purwokerto, Banyumas, Cen tral Java.Cooperative comes from the Latin terms "cooperativus", "cooperative" (in English), or "cooperatief" (in Dutch).In the Indonesian context, these terms refer to collaboration, cooperation, or joint work [1].Like a student coopera tive, Sacika cooperative provides various kinds of needs of Telkom Institute of Technology Purwokerto students.This cooperative sells a variety of needs, such as stationery, merchandise and others.
Resources involved must be accurate and skilled in distributing goods to end consumers.[2].Supply Chain Management is the integration of interre lated business processes between internal and external aspects of the company, starting from suppliers to consumers [3].Without a supply chain network, comp any operations cannot run normally [4].Therefore, it is necessary to measure the performance of SuppIy chain cooperative sacika Telkom Institute of Technology Purwokerto using the SCOR (SuppIy Chain Operation Reference) method.
The SCOR method is one of many approaches to measuring supply chain performance.Implementing Supply Chain Management helps reduce inven tory costs, including storage, ordering, and shortage costs.[5].For example, SCOR can organize and supervise shipping and procurement calculations by considering capital and profit aspects [6].The SCOR model is superior to other models because it is able to identify problems from the internal and external activities of a business [7].This method has six processes, namely plan, source, make, deliver, return, and enable [8].There are 5 attributes which are reliabi lity, responsiveness, agility, cost, and asset management [9].6 The process is level 1 of the SCOR method itself [10].Despite its simplicity, SCOR has proven to be an effective tool for supply chain description, analysis, and improvement [11].Therefore, researchers conducted research on measuring the performance of the Supply chain using this method has been done [9], [10] , [12].
Research [13] It highlights the significance of maintaining and measuri ng performance to thrive in dynamic and competitive business environments.The study identified fifteen metrics across three performance attributes: five for reliability, nine for responsiveness, and one for cost.The overall performance score is 72.73, aiding in maintaining and enhancing business performance.
The investigation [14] the focus is on minimizing adjustments while meeti ng customer demands and service requi rements.Research shows an outstanding Perfect Order Fulfillment (POF) rate of 98.72%, indicating high efficiency.Additionally, Order Fulfillment Cycle Time (OFCT) has decreased to 8 days.Cost of Goods Sold is at 75%, represe nting a substantial portion of operational expenses.
The objective of this study [15] to comprehensively assess the supply chain management performance of port opera tors in Indonesia by utilizing the SCOR Model.The focus is on understanding and appropriately evaluating the proces ses involved in logistics business within the main ports of the country.
The research titled "Assessing Hal al Supply Chain Performance through Analytical Hierarchy Process (AHP) and Supply Chain Operations Reference (SCOR) 12.0 Approach: A Case Study" [16] explores the performance evaluation of the supply chain.The findings reveal that the supply chain performance of XYZ Supermarket from January to Ma rch 2021 reached an impressive 97.91%, indicating excellent performance.
Research Title: Evaluation of Perf ormance Utilizing the SCOR and AHP Methodologies Research Outcome: The Conclusive Supply Chain Performance Score for PT.X is 80.54.This score is considered favorable, falling within the "good" category as final results ranging from 80 to 89 signify satisfactory perfor mance [17].
The enhancement in supply chain performance of a printing services comp any, as per the SCOR model, indicates that while the Make and Source metrics achieved high scores of 99.0 and 95.0 respectively, the delivery process scored the lowest at 80.0 in the performance measurement [18].
The implementation of a SCOR model-based meat supply chain performa nce measurement information system provides quick interpretation and under standing of supply chain performance across multiple dimensions such as reli ability, responsiveness, resilience, cost, and assets.Each metric is customized to meet the specific needs of individual stakeholders in the supply chain.[19].
Research on Performance Improv ement Strategies for Automotive Compan ies with the SCOR Model and Critical Performance Analysis shows that the average supply chain performance in 2019 [20] was 82.14%, a "good" category, indicating a satisfactory level of performa nce.
Measuring and improving Supply Chain Network Performance through DEA and SCOR Models [21] showed that in some cases, DEA method yielded lower performance than SFA method.Average performance for DEA was 0.80, slightly lower than SFA's 0.82.Identi fication of indicator deficiencies and stage-wise improvements led to prog ressive efficiency enhancement.Overall average performance during dynamic peri od reached 0.90.
The purpose of this study is to assess the quality of the SuppIy chain process in the sacika cooperative, especially in the process of procuring alma mater suits, after knowing the supply chain process from the results of observations and interviews, a perform ance measurement of the cooperative supply chain will be carried out.

METHOD
The supply chain is a series of ongoing business processes, a series of processes that distribute production obje cts and services to customers.The series runs by taking into account the factors of timeliness, cost and quantity of goods.The consideration of choosing the ITTP sacika cooperative in the case study is that the ITTP sacika cooperative has a flow where a supply chain runs.
Methods the data collection method used in the research is descriptive quantitative.The purpose of using quantitative descriptive methods is the depiction or description of the facts owned by the field.Furthermore, data containing facts in the field were analyzed using the SuppIy Chain Operation Reference method or SCOR for short.
Image 1. Five main processes in the SCOR method Image 1 displays the 5 processes of the SCOR method.The planning pro cess starts with identifying raw material requirements, planning production, and optimizing inventory.The second process is supplier source selection, followed by the third process, Make, to process materials into products with strict quality management.Product delivery to campus cooperatives and inventory management in distribution warehouses are done in the fourth process, Deliver.The last process, Return, handles product defects or nonconformities by evaluating the causes of returns and improving the process.The OFCT formula is the total time required for all orders to be delivered.COGS Formula: -COGS: (2) Description: Beginning inventory : Total inventory at the beginning of the period Purchases during the period : The total amount of goods purchased during the period.
Ending inventory : The amount of inventory remaining at the end of the period.
-COGS(%) : (3) Description: COGS : Cost of Goods Sold Total Orders : Total number of orders received CTCCT Formula: (4) Description: Supply inventory : Quantity of goods on hand Average accounts receivable : The average amount of receivables over a period of time Average accounts payable : The average amount of debt over a certain period of time.
The results of SCM performance measurement are obtained by looking at four SCM parameters, namely reliability, responsiveness, flexibility, cost and assets.Then from the analysis of SCM performance measurement results will produce output in the form of SCOR CARD.
Data analysis can be done using the SCOR CARD In Table 1, there are performance attributes consisting of 4 parts, namely supply chain reliability with POF matrix calculation to measure the extent of sup ply chain reliability in avoiding failures or problems that can affect the availa bility of goods, supply chain responsiv eness with OFCT matrix calculation to measure supply chain responsiveness to customer demand, supply chain cost with COGS matrix calculation to measure the efficiency of production costs in the supply chain, supply chain asset manage ment with CTCCT matrix calculation to measure the time it takes to convert financial investments into reusable cash flow.
Benchmarks are used to set perfo rmance targets and direct SCM develo pment.Comparison between actual perf ormance and benchmarks of similar com panies is used to identify performance gaps and calculate opportunities.Gap Analysis helps set performance targets based on benchmark data.Supply chain improvement is based on SCM parame ters, benchmarking, opportunities, and Gap Analysis to produce SCM improve ment solutions.SCM performance impro vement is the final stage to increase the success of Sacika ITTP Cooperative.

RESULTS AND DISCUSSION
The sacika cooperative network system has various entities involved, nam ely fabric suppliers (suppliers), convec tion (manufacturing), and sacika coopera tives (retail).The flow of the sacika cooperative supply chain starts with the selection of materials and colors from fabric suppliers.After that, it continues with sewing materials, packing goods, then stored in the warehouse to be delivered to the sacika cooperative.The next stage, the sacika cooperative sells to customers, namely ITTP students.Mean while, there is a flow in the illustration.
