Entrepreneurial motivation of farmers in growing entrepreneurial intentions for farmers in increasing agricultural productivity and business sustainability is an important variable in agribusiness development in the Indonesia-Malaysia border region. This study aims to determine 1) the influence and relationship between entrepreneurial attitudes, subjective norms and self-efficacy on entrepreneurial motivation, 2) the influence of entrepreneurial motivation on entrepreneurial intentions. The population in this study were farmers in five sub-districts in the border area of Sebatik Island with a total sample of 250 farmers determined by purposive sampling method. Testing the data analysis model developed in the study used the Structural Equation Model (SEM) assisted by the AMOS program. The results show that the overall model built in this study meets the model fit norms, which means that the model developed in this study is in accordance with existing empirical conditions. There is a significant influence and relationship between entrepreneurial attitudes, subjective norms, and self-efficacy on entrepreneurial motivation and entrepreneurial motivation has a significant and positive effect on farmers' entrepreneurial intentions on Sebatik Island, the Indonesia-Malaysia border region.”

Agricultural practices and water availability are highly correlated with sustainable watershed management. The Sebuku and Sesayap watersheds have a role to play for water conservation and support for agricultural practices. The research aimed to investigate, assess and map the carrying capacity of the environment in the supply of fresh water and food. The method is carried out using a mathematical model, Simple Additive Weighting to calculate the area of each carrying capacity category using ArcGIS 10.7 programs. This ecosystem service approach is used to measure carrying capacity. The approach is based on the assumption that the higher the performance of ecosystem services, the higher the carrying capacity of the environment. Carrying capacity is the maximum number of populations that can be sustainably supported by a local ecosystem, meaning that it has a carrying capacity and assimilation capacity. The results show that the application of the Simple Additive Weighting model has advantages over the expert-based valuation method which has been widely used, which proves convenience in the investigation and assessment process. Investigations and assessments show that the function of the Sebuku and Sesayap watersheds as a food providers is dominated by high category areas (Iecc 3.41 – 4.20) with an area of 1,178,843.93 ha. Meanwhile, the Sebuku watershed is dominated by the medium category area (Iecc 2.61 - 3.40) with an area of 850,633.60 ha. In addition, the environmental carrying capacity of the downstream watershed area in providing fresh water tends to be low (Iecc 1.81 – 2.60) even though the environmental carrying capacity of the downstream area as a food provider is high (Iecc 3.41 – 4.20), because these areas are generally fluvial plains and coastal plains which are used as pond cultivation areas. Overall, watershed conditions tend to experience a decrease in carrying capacity, both in terms of providing food and fresh water. Therefore, to achieve sustainable watershed management, it is necessary to use a food commodity-based water conservation approach with the application of dry land agroforestry practices in the middle region, and silvo-fishery in the downstream area.
