To increase the renewable energy mix in Indonesia, the Indonesian government has implemented a mandatory policy for the use of a 20 percent biodiesel blend (B20). This policy is a part of an effort to realize Indonesia's commitment to reduce greenhouse gas emissions by 29% by 2030. This policy also aims to increase domestic palm oil consumption in Indonesia as the largest palm oil producer globally with a total land area of 14.99 million hectares or equivalent to 49.5% of the world's total oil palm land. However, the utilization of renewable energy that can be achieved currently is only around 11.5%, still far from the target of 23% by 2025. The low use of renewable energy is certainly a challenge for the Indonesian government to enhance biodiesel adoption as renewable energy by raising the percentage of biodiesel blended. However, such an enhancement is arduous to do due to the complexity of biodiesel adoption. While capturing biodiesel adoption complexity is important before moving to the next biodiesel blended plan, there is an insufficient effort on this matter. This paper aims to understand the complex structure of biodiesel adoption in Indonesia. For this purpose, a conceptual model of system dynamics approach is developed to analyze the biodiesel adoption complexity and its related policy. The result shows that many underlying factors affecting biodiesel development are considered in designing policies to increase the adoption of biodiesel in Indonesia. Further, the government mandates and subsidies seem to take the most determining factors as the government intervention for increasing biodiesel adoption.

Scheduling is a crucial point in the manufacturing process of Polymer Dispersion in a Polymer Dispersion Plant, especially for a plant that has a limited amount of storage tank. The optimization of scheduling is needed to avoid any bottleneck and achieve the optimum flow time and production cost by simulation modeling with Discrete Event Simulation. The best scenario on assigning and sequencing the product to be produced within the horizon of time can be observed. In this study, we analyze scheduling performance by testing all factors with two criteria: average product flow time and the cost of production. We conduct three phases process in this frame fork. In the first phase, we create the design of experiments to state the pre-defined process factor that affects the performance criteria. We make a simulation model of the Polymer dispersion plant based on the actual data and the second phase. The last phase calculates the aggregate of two performance criteria with Grey Relational Analysis to determine the best scenario. Based on the analysis in this study, among the other factors, the quantity rule and the reaction time rule have the most significant effect on the performance of production scheduling in the chemical plant, which the Polymer Dispersion Plant represents.

The COVID-19 pandemic has been going for more than one year since the first time discovered in Wuhan, China in December 2019. As of February 2021, the COVID-19 pandemic has reached more than 109 million confirmed cases and more than 2 million death cases worldwide. Many areas in life are badly affected by the pandemic such as health, economics, business, education, political, international relations and social life. Business is one of areas that is most affected by the COVID-19 pandemic. Many companies and organizations adjust their working schedule and doing anything to survive from running out of business. They keep going despite the circumstances which means their employees are working during the pandemic. Working from office (WFO) during pandemic is risky because highly transmittable virus and unavailability vaccine and medicine. Even though preventive measurement has been applied, the feeling of fear and anxiety in employee could not be avoided. This study we will investigate correlation between fear of COVID-19, behavior and employee performance in service and manufacturing industries, that are connected to Protection Motivation Theory (PMT) and Theory Planned Behavior (TPB). An online questionnaire is created by collecting variables and constructs from previous studies. Then interviewing some experts to evaluate and validate them. In the future, a Structural Equation Modelling Partial Least Square (SEM-PLS) will be used to examine correlation and relationship of variables and constructs.

Micro and Small Medium Enterprises (MSME) in Indonesia have been providing significant economic development and employment. The majority of MSMEs are the micro-business sector; one is the traditional shop or Warung in Bahasa. Given the contributions, the MSMEs owner faces crucial obstacles, mainly in supply chain issues and their lack of perception and readiness to meet industry changes thanks to their informalities. The owners could leverage innovation in a business partnership and ICT (Information, Communication & Technology) adoption as leverage to overcome these obstacles and increase their capabilities. In Indonesia, startups highlight these issues to initiate a business partnership entity that integrates ICT into the traditional shop's business process. Previous studies confirm that business relationships positively impact small business performance, which will contribute to their success. However, the lack of understanding about factors contributing to business partnerships' success leads to the inability to achieve their goals. Given the MSME business entity's informalities, restrained resources, and the novelty of this business relationship, the understanding of its success factors becomes essential. Thus, this study intends to identify the Critical Success Factors (CSF) of traditional shop and startup business relationships using literature reviews and field interviews validated by industry experts. This study's outcomes would help the stakeholders identify the factors which essential to lead these relationships achieving their goals and empowering the MSMEs owner at the same time.

Economic growth and urban development have induced environmental damages. It because of plastic consumption never stops increasing, and make it into environmental pollution. The contribution of noodle wrapper into environment has become significant since Indonesia is the second biggest instant noodles’ consumer in the world. As the most rapidly urban development and populous area in Indonesia, Jabodetabek (Jakarta-Bogor-Depok-Tangerang-Bekasi) contributes to the high plastic waste generation. Separation waste at source is important for the successful of any waste management. However, the waste separation behaviors are not common in Indonesia and the study about residents’ separate intentions for noodle wrapper is scarce. For filling this gap, we have tried to identify the critical factors that affect the residents’ intention towards noodle wrapper separation. Data drawn from 435 questionnaires were used to assess demographic factors and the TPB constructs (i.e. attitude, subjective norms, perceived behavioral control, knowledge, past behavior, willingness to accept, intention, and behavior). Results of this study showed that subjective norms had the most significant influence on the intention of noodle wrapper separation followed by past behavior, attitude, and knowledge. While perceived behavioral control and willingness to accept do not have a significant effect on the intention of noodle wrapper separation.

The circular economy aims to utilize natural resources and reduce the large amount of waste that impacts the environment. Although many studies had identified various advantages of adopting a circular economy, only a few studies have investigated the risks of adopting a circular economy context. Therefore, to fill this research gap, this study proposes a preliminary risks assessment of adopting circular economy initiatives in the Indonesian plastic supply chain. First, this study performed a literature review to identify risk criteria in the plastic manufacturing supply chain's circular economy initiative. Second, it continued by interviewing the experts to validate the identified risks. Right experts are involved in rating the criteria on a four-point Likert scale. From expert appraisal, this study established eight risk categories and 31 specific risks for further analysis.

Crude oil is one of Indonesia's most significant revenue from its export. However, crude oil is also a burden in import spending to fulfill the high demand for its derivative product, fuel oil. This issue is driven by the decline of crude oil production and sluggish upstream activities to replace the depleted oil reserves, which are also affected by low crude oil prices in the market. The upstream oil activities such as exploration and exploitation mostly operated on onshore instead of offshore, so the offshore’ undeveloped oil reserves are still vast and promising. Therefore, there is an urgency to set the crude oil production recovery strategies by focusing on the offshore upstream sector. However, the offshore upstream macro processes are complex and dynamic, need a holistic view to understand their structure, causal relationship, and behavior over time. This study proposes a conceptual model based on the System Dynamics approach to comprehend those dynamic complexities. It will be modeled through one of the biggest and oldest offshore oil companies in Indonesia as a representative to produce the strategies. The conceptual model shows that the exploration sectors should be more prioritized to ensure the sustainability of exploitation activities and crude oil production recovery in the future.

The government of Indonesia (GOI) has committed to accelerating electric motorcycles adoption for reducing transport sector emissions. A battery swapping scheme is an attractive option for the GOI to solve several impediments to electric motorcycle adoption related to short milage, charging times, and initial investment costs. However, the battery swapping policy alone seems ineffective in supporting emission reduction targets since Indonesia's grid electricity source is still dominated by fossil energy. Therefore, it is crucial to introduce a green battery swapping concept. It is a concept that integrates the battery swapping scheme with the use of solar energy as its primary energy source for the battery. However, creating a sustainable green battery swapping industry should be assessed as a complex system. Hence, a holistic view is needed to understand the system process and determine the relationship between related elements. This study aims to develop the conceptual model of a sustainable green battery swapping business development using system dynamics modeling. The conceptual model translated into a system diagram and a causal loop diagram (CLD) provides initial information that solar PV capacity, carbon credit, and incentives for charging stations are the main variables impacting the sustainability of a green battery swapping industry.

This paper aims to assess the supply chain resilience in the nickel mining industry in Indonesia. Problems arise in the supply chain for the Indonesian mining industry, i.e. the existence of laws regarding the export ban on nickel ore and policies regarding industrial downstream which hamper the process of nickel refined production because it is still unable to carry out downstream activities. When the export ban on nickel ore was imposed, the demand for nickel fell sharply which caused the reference nickel price to fall. Furthermore, carbon emissions resulting from mining and nickel processing can also damage the environment if not handled properly. The supply chain needs to withstand disruption and recover from a disruption quickly. This study utilizes a part of System Dynamics methodology, i.e. Causal Loop Diagram Analysis. The methodology consists of literature review, qualitative model development and expert interviews. The results show a validated causal loop diagram that could become a basis for the dynamic assessment for the systems under scenario.

The transportation demand in urban areas is driven by high mobility needs. However, in urban areas such as Jakarta, people propensity to use private transportation rather than public transportation even though modern public transportation is available. Consequently, the continued increase in the modal share of private vehicles was a matter of concern in the context of public transport services and the number of users. This paper wants to address this concern holistically by using the system dynamics approach. System dynamics is being used to developing a conceptual model of the dynamic complexity in Jakarta's transportation sector. By capturing the elements involved in the transportation system, this study also aims to capture key factors that may play significant roles in increasing services and the number of users. Such a holistic view could provide insights for possible effective measures that the government can take. The system diagram revealed the system's key components and stakeholders that involved in the transportation system in Jakarta.
