Minimization Risk Product Quality of Stolephorus Sp. Fish in Supply Chain Activities

In supply chain activities, there is always the potential for risk to arise, therefore risk management is needed for risk control. PT. Marinal Indorima Kapedi is a manufacturing company engaged in fisheries, which processes raw materials of Stolephorus Sp. fish where supply chain activities have the opportunity to pose risks that cause a decrease in product quality. The purpose of this study is to identify quality reduction risks and risk agents that occur in supply chain activities then design mitigation strategies that can be used to reduce the emergence of risk agents. The method used to determine priorities and mitigation strategies is House of Risk (HOR). From the results of the study 7 proposed mitigation strategies were proposed to reduce the possibility of the emergence of risk agents in the company's supply chain activities, namely conducting routine training for all workers, setting a standard time for each process on the production line, implementing production machinery instead. workers, oversee every tighter work activity, coordinate with suppliers, apply a system of violations to contract workers if the working mechanism is not in accordance with the SOP, and take Stolephorus Sp. fish only for trusted suppliers


Introduction
PT. Marinal Indorima Kapedi is a manufacturing company engaged in the fisheries sector, namely processing raw materials for Teri fish located in Sumenep Regency, East Java. The final products are almost entirely exported and marketed to foreign countries such as Japan, Singapore, China, Hong Kong, and Thailand.Problems faced by PT. Marinal Indorima Kapedi currently includes complaints from consumers about the quality of Stolephorus Sp. fish products because cases of refusing class fish are rejected, it is alleged that the case of rejection is not only caused by a production process error, but there are other factors outside the production process that increase the risk of rejection. In the production process the risk of process failure in the form of undercooked fish because the boiling temperature is not optimal, the fish is damaged due to excess production, the fish is damaged due to damage to the tools and machines, and the fish is damaged due to handling errors.
Risk can cause damage which may affect the company's goal [1]. The existence of some sort of risk needs to be identified to map the characteristics of the risks that will have an impact on the performance of Supply chain [2]. If a company does not have a risk management, then the risk can have an impact on the company's performance [3]. HOR (House of Risk) was * Corresponding author : jufriyanto@umg.ac.id chosen because it has a set of proactive which is considered effective in managing the risk of supply chain companies. A method HOR is a method that focuses on formulating the strategy of prevention, response and handling of risk factors potentially cause risk of more than one [4]. Model HOR used to prioritize which dealt first and to choose the most effective action to reduce the risk of potentially appear by agent risk. A method HOR had used to analyse risk on leather raw materials in a company [5] and to manage risk the quality of the frozen shrimp in the supply chain [6].
The Focus this study to identify and analyze risks in the supply chain then design appropriate mitigation strategies to deal with risks so that the company can minimize losses and achieve the purpose to identifying and measuring risks potential that exist in supply chain activities of PT. Marinal Indorima Kapedi can use the House of Risk model which is the development of Failure Modes and Effect Analysis (FMEA) and Quality Function Deployment (QFD) methods. According to [7][8] [9], risk management is the process of identifying, measuring, and ensuring risk and developing strategies to manage those risks. The aim is to continue to make or add maximum value to all activities in an organization.

Supply Chain Risk Management
According to [11] [12], Supply Chain Risk Management is a tool that's might be minimize possibility of things that can cause failure in one aspect of the supply chain so that the overall performance of the supply chain cannot function properly.
According to [13] [14], Supply Chain Risk Management is a risk that occurs in the flow of products, information, ranging from raw materials to delivery of the final product. This risk threatens overall supply chain from suppliers to consumers.

House of Risk
Model House of Risk is one of framework by doing the development methods of Failure Modes and Effects Analysis and Quality function Deployment [15]. FMEA is a method used to identify the potential of a failure of a product or service as well as performing an act which aimed to eliminate or minimize the risk of failure [16][17] [18].
While the QFD is a process set the customer's wishes (what is "desirable" customers) and translates it into "how" attribute so that each functional area can understand and execute it [19] [20].

Methods
The method of completion in this study using the House of Risk method which is a development of the Quality Function Deployment method and Failure Modes and Effect Analysis.

House of risk.
The following are the stages of House Of Risk (HOR)

House of Risk phase 1
From each risk event and risk agent, then it is followed by mapping Aggregate Risk Potential (ARP) value with phase 1 HOR matrix. This matrix maps the correlation of risk events with each risk agent. a scale of 0, 1, 3, 9 where 0 indicates no correlation and 1, 3, 9 shows successively low, medium and high correlation.

Make Pareto diagram
Make a Pareto (Aj) diagram for priority selection. Pareto diagram is used making rank of data indication based on the percentage order. left for lowest value of ARP Aggregate Risk Potential in HOR and right for highest value. The biggest percentage will be improved by conducting phase 2 HOR, which is looking for strategies for the proposed risk mitigation steps TEk values are calculated by the formula: TEk = ∑ ARPjEjk (2) ARPj= Aggregate Risk Potential from risk agents Ejk= Correlation between mitigation strategies and risk agents The ETDk value is calculated by the formula: ETDk = TEk / Dk In phase 2 HOR or risk handling phase which aims to determine the priority of actions with TEk calculation (total effectiveness) and ETDk (Ratio between Total effectiveness and level of difficulty).

Risk Evaluation
The purpose of risk evaluation is to make which risk decisions are categorized as critical and need to be addressed. A tool that can be used to decide which risks need handling first, including Pareto chart.

House of Risk phase 1
The following results from House of Risk phase 1:  Figure 3, it can be seen that there are four selected risk agents that will carry out mitigation actions, namely A16 (Prolonged waiting time in process), A11 (Lack of ice cubes), A24 (Boiling process too long) and A21 (Operator works outside the SOP). The four risk agents were chosen because they had the most influence on the decline in product quality which would have an effect on the company's income.

Mitigation of Risk
The next stage carried out in the risk management process after the risk evaluation is the risk mitigation stage. Where at this stage the chosen risk agents will be included in phase 2 HOR for develop mitigation actions. The mitigation action in question is an action to reduce the impact of a risk agent that appears in future. Mitigation actions are measuring from normalization of the company. The following is a mitigation action that is obtained in accordance with the objectives of the company.

2 nd phase House of Risk
In phase 2 HOR or risk handling phase which aims to determine the priority of actions with TEk calculation (total effectiveness) and ETDk (Ratio between Total effectiveness and level of difficulty)

Conclusion
Based on the Pareto diagram analysis obtained four priority risk agents that need mitigation actions, namely A16 (the waiting time in the process is too long with the Aggregate Risk Potential (ARP) value of 504, A11 (Lack of ice cubes) with an ARP value of 486, A24 (process boiling too long) with ARP values of 432 and A21 (Operators working outside SOP) with ARP values of 402 of the 4 selected risk agents, 7 strategies were proposed to the company, the seven strategies were ranked by calculating the value of ETD (Effectiveness to Difficulty).
Authors would like to thank DIPA FT UTM 2020, because this article accessing this foundary. for further research can take note of any failure of any business processes to make it easier to do risk management. In addition, the identification of the risk starts from means of transport from suppliers because it can also cause a high risk on loss of quality.
