Production And Consumption

Indonesia biodiesel blending mandate emerged in 2006 driven by strengthening energy security while in parallel reducing and toning down the need for fossil fuels, strengthen the country's balance of payments and increasing environmental demand to reduce CO2 emission while leveraging the abundance of Crude Palm Oil as raw material. The purposes of this study were to analyze production and consumption of palm Oil-based biofuel. System dynamics model was developed based on 4 stages, Palm Oil Plantation, CPO Production, Palm Oil-based biofuel production and consumption and the validation of the model through Mean Absolute Percentage Error (MAPE) test confirms the correspondence between structures and phenomena. Baseline simulation analysis shows that there is no single strategy capable of improving the production and consumption of palm-based Palm Oil-based biofuel. We suggest that combined strategies such as government support hand in hand with industrial conversion efficiency, increase in palm oil on-farm productivity, 5% reduction in CPO export, Increase biodiesel production capacity and generally biodiesel utilization target cannot be achieved without the support from the government in form of subsidy which require additional IDR 409 a 15% increase in subsidy.

Per Capita Consumption

The per capita consumption of beef in Nigeria is reducing amidst a rising population that is dependent on beef as a major source of animal protein. In this paper, a system dynamics (SD) model was developed with the aim of testing exploratory policies aimed at reversing this trend. The simulations of various policy tests showed that, of all the policies tested, having a higher carcass yield seems to be the most efficient solution, but its feasibility faces some steep biological and ecological challenges. However, a combination of policies that cuts across the land–cattle–market nexus is necessary to obtain a consumption level that almost meets the World Health Organization (WHO) standards for recommended animal protein intake. Complex inter-linked systems, like beef production and consumption, require a systemic approach that considers dynamic feedback to avoid fixes that fail or shift the burden when making policy decisions.

With the technological developments and rapid changes in demand pattern, diverse varieties of electronic products are entering into the market with reduced lifecycle which leads to the environmental problems. The awareness of electronic products take-back and recovery has been increasing in electronic products supply chains. In this paper, we build a system dynamics model for electronic products closed-loop supply chain distribution network with the old-for-new policy and three electronic products recovery ways, namely, electronic products remanufacturing, electronic component reuse and remanufacturing, and electronic raw material recovery. In the simulation study, we investigate the significance of various factors including the old-for-new policy, collection and remanufacturing, their interactions and the type of their impact on bullwhip, and profitability through sensitivity analysis. Our results instruct that the old-for-new policy and three electronic products recovery ways can reduce the bullwhip effect in the retailers and the distributors and increases the profitability in the closed-loop supply chain distribution network.

Derivative Products

Indonesia is one of the largest palm oil producer in world. The products of palm oil derivative diverse, ranging from cooking oil, margarine, soap, and biodiesel. So far, Indonesia is more likely to export Crude Palm Oil (CPO) to various countries. But on the other hand, Indonesia need to reduce the burden imports of some palm oil derivative products such as cooking oil, biodiesel, and soap. It is therefore, we need a breakthrough to improve the production of crude palm oil and its derivative products so that we can increase the availability of the derivative products. Based on this existing condition, we need an approach that can analyze the use condition of the palm oil derivative products and improve the palm oil use of derivative products in the future. Therefore, in this research, we will develop a model that can analyze and develop some policy scenarios to improve the utilization of palm oil derivative products. The method used for the model development is system dynamics, based on the ability to accommodate the internal and external factors that affect the production of palm oil derivative products.From the model scenarios we obtained that by sorting the fruits harvested, so that the levels of Oil Extraction Rate is at 22.1%, it can increase the stock of CPO by 11%. By utilizing 50% of CPO for the cooking oil production will meet the needs of the national cooking oil demand, with a ratio of 1.5 fulfillment began in 2010. If we utilize 35% of CPO to be processed as stearin, and use 10% of stearin in the soap contain, it will fulfill the need of domestic soap until 2015.  By utilizing the empty fruit bunches waste as raw material for biodiesel, there will be additional biodiesel production of around 920,479 kilolitres in 2019. Meanwhile, the use of 1% of CPO production to create biodiesel, it will make biodiesel production reaches 31,173 kilolitres in 2019.  From these efforts, there will be 951,652 kilolitres biodiesel production in 2019.

Using Indian free-ranging dogs (FRD) as a case study, we propose a novel intervention of social integration alongside previously proposed methods for dealing with FRD populations. Our study subsumes population dynamics, funding avenues, and innovative strategies to maintain FRD welfare and provide societal benefits. We develop a comprehensive system dynamics model, featuring identifiable parameters customizable for any management context and imperative for successfully planning a widescale FRD population intervention. We examine policy resistance and simulate conventional interventions alongside the proposed social integration effort to compare monetary and social rewards, as well as costs and unintended consequences. For challenging socioeconomic ecological contexts, policy resistance is best overcome by shifting priority strategically between social integration and conventional techniques. The results suggest that social integration can financially support a long-term FRD intervention, while transforming a “pest” population into a resource for animal-assisted health interventions, law enforcement, and conservation efforts.
