Abstract

Food security is a high-priority issue for sustainable global agricultural development both quantitatively and qualitatively. Maize is one of the most important food crops in the world after rice and wheat. The biggest contribution of maize production in Indonesia comes from East Java Province, which is 25,60%. Maize production is changing due to increased consumer demand, increased input costs, concerns about food security, and environmental impacts. Climate conditions of marginal land areas (drought) and the use of chemical fertilizers continuously have negative impacts on the amount of production, food security, and soil quality (environment). This situation is dangerous because it will affect the income from farming. Based on these problems, in this study, a system dynamics prospective study will be conducted to develop a conceptual model (Causal Loop Diagram) to increase eco-friendly maize production to support food security. The results of the study are conceptual models that have some important information regarding internal and external factors that affect the productivity and production of eco-friendly maize. The conceptual model produced can be used by the government and stakeholders for decision-making in developing strategies and policies related to eco-friendly maize cultivation systems to support food security. Further research can be done by developing several scenarios to predict the state of the maize farming system in the future.

Abstract

Salt is a very important commodity for human life. In addition to consumption, salt is also needed in several industries, including for the Chlor Alkali Plant (CAP) industries, pharmaceutical, and non-CAP industries such as petroleum, salting, and others. The demand for industrial salt in Indonesia continues to increase every year along with the growth and development of industries in Indonesia. However, the salt produced by Indonesian salt farmers is still low in quality and can only meet the needs of consumption salt because they only contain about 94% to 95% NaCl. Therefore, local salt is difficult to be absorbed by with salt-based products industry because its purity level does not meet the industrial standards. As a result, imports of industrial salt will increase because local salt cannot meet the industry needs. This study aims to build a conceptual model in order to improve the quality of salt in Indonesia in order to produce a good quality salt that meet the industrial salt standards and can be absorbed by the industrial sector in Indonesia with system dynamics approach. The results of this study are conceptual models regarding internal and external factors that influence the improvement of salt quality to meet the needs of industrial salt. The model can be used by the government and related parties in developing strategies and policies related to industrial salt cultivation. Further research can be done by developing several scenarios to predict future salt cultivation systems.

Abstract

The biggest carbon emissions in urban areas are generated from the transportation system, including in Surabaya City where the transportation sector contributes 5.48 million tons of carbon emissions per year, or about 96% of the total air emissions there. With the cities rapid development, urban transportation systems need to be managed appropriately to avoid environment damage. The most effective way to reduce carbon emissions from the transportation system is by reducing the number of private vehicles uses. TOD is one of the solutions that can be applied, which is through the integration of mixed land development and the construction of transit mode transportation systems. TOD allows people to carry out various daily activities with close transportation distances, either using transit modes, walking, or cycling. This study aims to show the benefits of applying TOD in reducing carbon emissions from the transportation sector in Surabaya using a system dynamics model. The model produced can be used as a reference or consideration for the government and other related parties in developing strategies and policies related to the implementation of TOD. Future studies can analyze several TOD scenarios that can be carried out to reduce carbon emissions from the transportation sector in Surabaya.
