Abstract

Microbial contamination, instability in production yields and cell lines are the challenges that must be faced by any pharmaceutical biotechnology industry when conducting cell culture as one of the stages of its production process. In the past, Company X has experienced twice contamination cases during cell culture process for its recombinant protein products. As a result, Company X suffered financial lossess at approximately 3.05 billion rupiah and resulted in disruption of the stock of recombinant protein drug which are the active pharmaceutical ingredient for most of injection products. Therefore, an effective mitigation strategies are needed to manage any potential risks in the cell culture process. This study aims to design a risk mitigation strategy for risk in cell culture process by using House of Risk (HOR) method. There are two HOR matrices used in this study. HOR1 is used to determine which risk agents should be prioritized for prevention. In HOR2, several effective risk management strategies will be chosen. There are 40 risks events and 31 risk agents identified. Based on risk assessment results and applying Pareto Chart analysis there are two risk agents selected. Five proactive actions to mitigate these risks are proposed. They are training and personnel qualification program periodically, changing workflow become more efficient and convenient, more detailed revision of related documents, changing manual process to semi-automatic process gradually and additional person on each team as a verifier for double-checking.

Abstract

Lean is an approach that is carried out continuously to identify and eliminate waste or other activities that do not provide added value. Many companies have implemented lean concepts and got the benefits such as reduced cycle time, reduced operational costs, improved product quality, and other benefits. Although it provides many benefits, there are some weaknesses in implementing lean, one of which is due to the lack of monitoring. After the initial implementation, the process has never been reviewed and is rarely checked to ensure its implementation. Monitoring lean implementation requires tools that can help monitor work more efficiently. There are no specific tools that can be used to control and oversee lean implementation in the company. For this reason, this research will develop a tool for monitoring lean implementation. The tools to be developed adopting the logic of several methods, namely Quality Function Deployment (QFD), the framework of three matrix houses in lean implementation, and the House of Risk (HOR). This Lean monitoring tool is used to ensure that the corrective actions recommended for lean implementation are implemented. The Lean monitoring tool consists of three matrices that offer the ability to identify potential failures, the root causes of failures, and solutions to deal with lean implementation failuress.

Abstract

Globalization and vast changing of business nature nowadays makes interdependence between organizations who shares the same supply network is becoming stronger.  Any risk that occurs in one point of a supply chain could affect to the whole network.  As a result, risk in supply chain is getting more complex and unpredictable. Since any kind of risk could potentially impede or even stop business activities of the whole supply chain therefore managing supply chain risk is essential. Moreover, to handle supply chain risk properly, the interrelationships between these risks should be identified. However, there is only few study which cover interrelationships between supply chain risks. This research is aiming to provide a proposed model of a supply chain interrelation risks based on case study in an petrochemical industry.   Interpretive Approach Structural Modeling is utilized to develop the relationships between risks while weight determination for risk relationship is conducted using Analytical Network Process.  The case study of this research identifies that there are 14 supply chain risks which are grouped as driver, dependent, autonomous and linkage. The weight of risk interrelations are then considered when quantify each risk.  Calculation of risk priority number is not only taking into account its own probability and consequence but also the probability and weight of affected risk.

Abstract

PT. XYZ is one of subsidiaries of state-owned company which has core business in Power Generation and Operation & Maintenance (O&M) Services for power plants. There are a lot of challenges that should be faced by PT. XYZ as a maintenance unit to achieve the on cost, on time and on quality target. Therefore, we need an analysis and risk mitigation in the procurement process of overhaul routine services to assist companies in dealing with potential risks. Risk identification is carried out using literature studies and expert panels. After that, the risk will be analyzed using the Analytic Network Process and House of Risk methods. The use of the ANP method in this study is as additional tools to support the HOR method because in this study it is possible to have a relationship between risk events and risk agents. This relationship is not captured by the HOR method because the HOR method only considers the relationship between the risk event and the risk agent. The results shows that there are 23 risk events that caused by 37 risk agents. Based on ARP result, there are 2 main mitigation efforts that can be done by the company which are increase the coordination between stakeholder and implemented the time-based contract for overhaul routine services. These efforts hopefully could help the company to reduce the probability of risk agents so the overhaul will not be affected.

Abstract

PT Y is a subsidiary of Y Group which specializes in producing speakers for local and international markets. At present PT Y's orders have not met the expected performance targets. Fulfillment of production orders reached 97.55% of the target of 100%. This is one of the concern of Y Group that PT Y need to improve themselves because it can result in companies becoming less competitive than competitors. Based on preliminary observations, there was indications of waste, namely defects, downtime, and process delays. The lean tool used for further waste analysis is Lean Assessment Matrix (LAM). The results of the research show that the waste which gives the most significant influences are transportation, waiting and inventory. The root causes of problems between work stations are not ergonomic, do not have preventative maintenance schedules, there are no standards for handling defective products, the layout of the room is not in the direction of material, the carrying capacity of hand trucks is small, and the Outgoing Quantity Check (OQC) processes are not included in the company’s time standards. The proposed improvement recommendations include conducting training to improve product repair skills, relayout of production plant, and making a preventative machine maintenance schedule.

Abstract

The concept of lean is originated in manufacturing industry. However, this concept also has been widely adopted in service industry, from airlines to retailers. There are several healthcares or hospitals in various countries that has implemented Lean. The hospital that has adopted lean, shown various improvements, such as increase on efficiency and flexibility, reduction cost and infections cases. It is important to have lean assessment to measure leanness level after implementing lean. Lean Assessment Tool is utilized to measure effectiveness and efficiency of lean implementation in a particular company. There are many studies on Lean Assessment Tool for manufacturing and service industry in general. However, Lean Assessment Tool that is specific for hospital is not yet available. Therefore this study aims to develop a Lean Assessment Tool (LAT) for healthcare. First, quantitative and qualitative dimensions and indicators are gathered from literature study. Proposed dimensions and indicators are then selected and validated using the Fuzzy Delphi method. There are seven quantitative dimensions, which are quality, time, internal transportation, employee involvement, cost, customer, and inventory. While, there are six qualitative dimensions, which are quality, process, employee involvement, vertical information system, technology upgrading, and management commitment. Measurement method by using fuzzy logic to calculate leanness level for both quantitative and qualitative indicator is then applied. Leanness level will be mapped using radar plots.

Abstract

Outsourcing has become the alternative scheme to gain improvement in several fields within a short time to many enterprises. One power generation in North Java implemented PM as planned maintenance strategy to maintain equipment by conducting insourcing and outsourcing scheme as PM execution. Both conditions must follow the same business process flow in PM execution process and there will occur some obstacles that interrupted PM process. The existing problem will be analyzed with House of Risk (HOR) method approach, supported by Integrated Manufacturing Open Systems Architecture (CIMOSA) process-based function modeling for identification method and Supply Chain Risk Identification System (SCRIS) risk structure identification used for mapping problem, root cause, and its relation. Analysis with HOR results in root causes that occurred within PM implementation process for both of them commonly has the same problem that is process business acknowledgment, but in outsourcing scheme not exist root cause on culture compliance and work task requirement, because they have a descriptive target to obtain service level agreement fulfillment. On both scheme still need an improving method to monitor and evaluate the PM work for better performance.
