Abstract

Soil fertility in land after nickel mining has a change in soil texture that changes both the profile color and the soil irregularity. Damage to the physical properties of the soil affects the soil nutrients needed by plants. Several physical and chemical properties of soil are influenced by texture including soil plasticity, soil permeability, ease of cultivation, lack of soil fertility and productivity. Stable soil fertility can support plant growth. Damage to the physical properties of the soil due to the loss of the soil interest (solum) by the ongoing washing of the soil. This results in the loss of some cations in soil colloids, resulting in low acidity (pH) of the soil becoming acidic. Cation Exchange Capacity (CEC) as the amount of charge of cations absorbed by soil colloids at a certain pH. Another factor in the decline in CEC is the decreasing number of cation nutrients that can be exchanged. The relationship with reclaimed and revegetated land is influenced by climatic factors with rainfall intensity. Soil fertility on revegetated land with CEC value and C-organic content was very low. Such soil fertility conditions are found in the revegetated zone with large leaf acacia (A. mangium) vegetation; sengon (P. falcataria); ketapang (T. catappa) and waru (H. tiliaceus). Soils that have low soil nutrient content are characterized by low organic matter content, very low available P content, and low cation exchange capacity.

Abstract

Pengelolaan lingkungan sumberdaya pesisir yang berhubungan langsung dengan manusia atau makhluk hidup lain yang ada di wilayah pesisir. Sebab interaksi manusia atau makhluk hiduo lain ditinjau dari aspek daya guna lingkungan sumberdya pesisir dari berbagai aspek manfaatnya di peruntukan untuk kelangsungan hidup baik aspek ekologis, ekonomi dan social masyarakat yang mendiami wilayah pesisir. Karena pengelolaan sumberdaya pesisir dengan karakteristik ekologi yang memiliki keanekaragaman jenis dengan memperhatikan aspek kelestarian lingkungan sumberdaya yang ada dan dilakukan secara terpadu dan berkesinambungan, akan mengurangi resiko ekologi antar kepentngan manusia pemanfaatan sumberdaya pesisir dengan karakteristik wilayah yang ada tetap berlangsung, akan menguras kenaekaragaman sumberdaya yang ada baik aspek ekologi, ekosistem dan social budaya danekonomi.
