Abstract

This research aims to identify the types and agroforestry systems of coffee plantations in Blang Gele, Central Aceh. The methods used are surveys and interviews. The results of this research show that there are 3 types of coffee varieties planted, namely Gayo 1, 2, and 3 varieties, interspersed with shade plants in the form of lamtoro, banana, cabbage, shallots, and andaliman with simple and complex agroforestry systems. The implementation of a coffee agroforestry system with economically valuable shade crops provides more diverse and higher income for farmers, which encourages farmers to optimize land use with a mixed cropping system, thereby increasing the sustainability of coffee farmers' income in the area. The conclusions of this research emphasize the importance of agroforestry systems in increasing the income of coffee farmers in Central Aceh through crop diversification. Thus, implementing agroforestry can be a sustainable strategy in cultivating coffee in this area.

Abstract

Mercury (Hg) belongs to a group of heavy metals that can pollute the environment. Pollution caused by mercury in the environment will cause bioaccumulation in aquatic biota, which then impacts human health. Mercury, especially in the form of methyl mercury, can be harmful to the central nervous system, causing sensory impairment and even permanent paralysis. Mercury pollution comes from various mining activities, industry, agriculture, household waste, and mercury mining itself. Accumulation of mercury in excess of quality standards can be dangerous and cause many negative impacts. This study examines pollution caused by mercury in Indonesian waters. The results showed that the objects most polluted by mercury are water, sediment, and aquatic biota. The highest percentage of pollution is found in rivers (39%), and the lowest in lakes and reservoirs (3%).
