MSMEs play a progressively important role in Indonesia's economic growth, particularly in the context of sharia economic development. The government and Islamic financial institutions (IFIs) have actively supported the empowerment of MSMEs in order to accomplish the Sustainable Development Goals (SDGs). This research aims to conduct a more in-depth analysis of the level of success achieved by these efforts. This research aims to utilize quantitative methods to identify the factors that influence the decision-making process of Micro, Small, and Medium Enterprises (MSMEs) when accessing Islamic financial services. Additionally, it seeks to measure the impact of these factors on the performance of MSMEs. The research results are expected to offer more efficient policy recommendations to enhance the involvement of IFIs in promoting sustainable growth of MSMEs. Research indicates that sharia finance does not have a significant impact on the sustainable performance of MSMEs. However, it is worth noting that sharia financial literacy does have a significant influence on the sustainable performance of MSMEs. Islamic finance exerts a substantial impact on the sustainable performance of micro, small, and medium enterprises (MSMEs). Moreover, the government's responsibility is to effectively regulate the connection between sharia finance and sharia financial literacy in order to enhance the long-term performance of micro, small, and medium enterprises (MSMEs).

LPG plays important role in Indonesia as household fuel. With the rapid growth of LPG usage, its handling facility is built across the country. The handling of LPG requires various activity prior to supporting its supply chain. One of the vital facility is Terminal LPG (or on this case Terminal LPG Semarang) which serve as a hub in LPG distribution because it handles a relatively huge amount of LPG. It is exposed to operational risk especially fire risk. This paper is intended to assess the risk of LPG Terminal by using combined both qualitative and quantitative methods. The initial step is to identify the hazard by using HAZOP Study. The next step is to determine the likelihood of the risk by using FTA and ETA resulted in event frequency. The severity level is determined using consequences analysis which involved fire modeling of the intended scenarios. The result from both frequency and consequences will be presented in the risk matrix to determine the unacceptable risk scenario to develop a mitigation plan by using Fire Risk Card to assess the capability of the Terminal firefighting equipment.

In the industry 4.0 era – a variety of new technologies to added value. Industry 4.0 is the end – to – end digitalization of all physical assets and integration into the digital supply chain with value chain technologies. Digital supply chain brings down those walls and the chain becomes a completely connected that is transparent to all the actors involved from the shippers of goods, delivery service companies, and finally to the customers. Logistics as part of the supply chain has an important role in Indonesia. Specifically, in delivery services. Currently, the tracking of the delivery service company can only be executed from one drop point to another drop point. A trip between drop points cannot be traced so that the tracking becomes not transparent. Logistics roles in delivery service company should utilize the Internet of Things (IoT) in handling customer who needs real-time transparency routes and monitoring of temperature-sensitive pharmaceutical cargo and perishable cargo. If this is implemented, delivery service companies in Indonesia can be crowned as the most advanced delivery service company in the world. The research information system uses a quantitative method. The data collection technique used in this research was collected by filling out a questionnaire. The result shown indicates that delivery service companies in Indonesia may use Traceable e-Seal that are connected to the MyTraceable application as a solution to transparency route, real-time monitoring of temperature-sensitive goods. We prompt to use MyTraceable application and smart lock because it can increase customer satisfaction and delivery service company performance.

Small and Medium Industries (SMIs) in the food sector play an important role in Indonesia's economic growth, but still face significant challenges in maintaining competitiveness amid increasingly fierce market competition and changes in consumer behavior. This study aims to analyze the implementation of the marketing mix (product, price, promotion, and distribution) at Sekotak Dari Dapur Bu' Sarhan SMI in Palu City, which is known for its innovative fishball products. The research method used is descriptive qualitative with a case study approach, involving participatory observation, in-depth interviews, and documentation with the primary informants, the owner and employees. The results show that local fish-based product innovation, cost-based pricing, and promotion through social media are the main factors in building the uniqueness and competitiveness of this SME. However, digital audience engagement is still low, and product distribution is limited to certain areas, so more creative promotion strategies and logistics partnerships are needed to expand the market. This research confirms the importance of adaptive and innovative marketing mix management. It provides practical recommendations for food SMEs to improve competitiveness through product innovation, price optimization, strengthening digital promotion, and expanding distribution networks. The findings are expected to be a reference for developing sustainable food SME marketing strategies in the digital era.

Supply chain models describe the activities carried out in the process industry. They are used to design and operate complex sequences of tasks that transform raw materials and deliver final products to markets. Many optimization models have been developed for supply chain planning because they offer the possibility of finding strategies that lead to greater economic benefits. The traditional models have focused on finding the optimal decisions of the supply chain planner in a deterministic context. However, it is widely recognized that uncertainty and external decisionmakers play a fundamental role in the economic success of industrial supply chains. This thesis proposes mathematical programming models for supply chain optimization that consider uncertainty and external decision-makers in a variety of industrial settings. Chapter 1 provides the motivation and the necessary background for our models. In Chapter 2, we study the design of resilient supply chains with risk of disruptions. Disruptions is a type of uncertainty that has not received much attention for supply chain planning, but it is known to have a significant effect in the performance of supply chains. We develop a stochastic programming model for supply chain design that includes disruptions at distribution centers, and a tailor-made solution method to address industrial instances of the problem. In Chapter 3, we present a novel cross-decomposition algorithm for investment planning under uncertainty. The algorithm integrates Benders and Lagrangean decomposition for two-stage stochastic programming formulations. Our computational experiments on instances of the resilient supply chain design problem show the superior performance of the cross-decomposition algorithm over Benders decomposition and direct solution with commercial MILP solvers. In Chapter 4, we propose a new approach for production planning and inventory management in process networks. Inventory management in these networks is a very challenging task because of the close interaction between production activities and the presence of diverse sources of uncertainty. Our planning strategy is based on implementing basestock policies iii to control production rates and inventory levels. Our results show the benefits of using a policybased approach for inventory planning in comparison to other stochastic programming approaches. In Chapter 5, we address the capacity planning problem with rational markets. Our model considers potential customers as rational decision-makers in a bilevel optimization formulation. We propose two reformulation techniques that transform the bilevel model into a single-level problem by replacing the lower level with constraints that guarantee its optimality. The reformulations are based on the Karush-Kuhn-Tucker conditions and the strong duality property of the lower-level linear program; the examples show better computational performance for the duality-based reformulation. The results also demonstrate the benefits of considering markets as rational decision-makers for capacity expansion planning, since it allows developing expansion plans according to the needs of the consumers. In Chapter 6, we extend the capacity planning model to include competitors that optimize their own capacity expansion plans. The resulting trilevel formulation considers as rational all decision-makers present in a competitive environment. We analyze the properties of the trilevel formulation and develop two algorithms to solve this challenging problem. The results reveal the complex interactions that take place in decision-making problems with multiple players and show the importance of considering them in the model. Finally, in Chapter 7 we present the conclusions of this thesis. We demonstrate that uncertainty and external decision-makers have significant impact in supply chain operations, and that our models can be used to anticipate their influence in supply chain performance. The application of these models for industrial supply chain planning has a remarkable potential to increase efficiency.

Economic Vulnerabilities and Livelihoods: Impact of <scp>COVID</scp>‐19 in Fiji and Vanuatu

The objective of this study is to enhance the resilience of the coal-to-liquids (CTL) industrial chain and supply chain to withstand increasing shock pressures. There is an urgent need to improve the resilience of the industrial chain and supply chain. This paper identifies 21 resilience-influencing factors from 4 perspectives: absorption capacity, adaptability, recovery capacity, and self-learning capacity; it then constructs an evaluation indicator system. The Interval Type 2 Fuzzy-Decision-Making Trial and Evaluation Laboratory-Analytic Network Process (IT2F-DEMATEL-ANP) method is adopted to determine the weights of the indicator system, and a resilience evaluation is performed based on the Interval Type 2 Fuzzy-Prospect Theory-Technique for Order Preference by Similarity to an Ideal Solution (IT2F-PT-TOPSIS) method. Furthermore, in the case of the CTL industrial chain and supply chain of China Shenhua Energy Group Ningxia Coal Industry Co., Ltd. (CENC) (Ningxia, China), this study ranks the resilience level from 2018 to 2022 to identify the factors that have contributed to a reduction in resilience and to implement measures to enhance the resilience of the CTL industrial chain and supply chain. The results show that the level of the CTL industrial chain and supply chain resilience was lowest in 2020, while it was highest in 2021. Factors such as the degree of domestication of key technologies, the rationality of the CTL industry layout, and the stability of supply and demand chains are identified as significant determinants of resilience levels. This points the way to enhancing the resilience of the CTL industry and supply chain.

Puyahan Hamlet in South Lembar Village is one of the traditional crab peeling centers (Portunus pelagicus) on the west coast of Lombok Island. Women in the informal work system dominate this activity without social protection or quality standards. Despite playing an important role in Indonesia's crab export supply chain, women peelers still face major challenges in technical and institutional aspects. This service activity aims to increase technical capacity and strengthen the institution of women crab peeler groups through training in the processing of fishery products based on the principles of food sanitation and facilitating the formation of legal business organizations. The methods used include participatory social mapping, technical training based on Good Manufacturing Practices (GMP) and Sanitation Standard Operating Procedures (SSOP), group institutional formation, and participatory evaluation. The results of the training showed a significant improvement in participants' hygiene understanding and practices, with an average pre-test score of 35.4 and a post-test score of 82.1. In addition, the establishment of organizational structures and institutional legalization allowed groups access to advanced training and wider economic opportunities. This intervention has been proven to be able to encourage behavior change, strengthen women's socio-economic position in the fisheries value chain, and support the gender empowerment agenda in coastal areas in a sustainable manner. The program recommends replication in other coastal areas with a gender-responsive participatory approach to strengthen the economic resilience of women's fishing communities.

Creative industries, especially Micro, Small, and Medium Enterprises (MSMEs), play an important role in Indonesia's GDP growth. However, many MSMEs lack adequate legal protection, especially regarding intellectual property rights such as copyrights, trademarks, and patents. This research uses a Normative legal method using a statutory approach, comparative approach, and conceptual approach. The research data is then analyzed and described descriptively, juridically, and normatively. Qualitative research processes qualitative data in the form of descriptive or narrative data. The results showed that Malaysia and Singapore are countries with large economies for Micro, Small and Medium Enterprises (MSMEs), with different approaches. Malaysia uses affirmative policies, fiscal incentives, and financing through SME Corp to empower MSMEs, with a focus on manufacturing and fiscal incentives. Despite facing challenges such as bureaucracy, low productivity, and global competition, MSMEs continue to grow. Singapore, on the other hand, emphasizes global competitiveness through support institutions and collaboration with multinational companies. Both countries are in the position that strengthening access to finance, skills training, and integration into global supply chains are critical to the success of MSMEs. Both countries stress the importance of coordinated policies, partnership strategies, and technological adaptation to build competitive MSMEs in the era of globalization.
