Judul: Pemodelan spasial dalam monitoring reforestasi Kawasan Pertambangan Nikel Pt. Inco di Sorowako Sulawesi Selatan
Abstrak: The success of the reforestation was expected to reach a climax forest ecosystem. The objectives of this study were to develop spatial model and to identify key indicators for monitoring reforestation success. The study used a comprehensive and systematic approach to obtain key indicators for determining the success level of reforestation in mining area. The success indices for each variable was derived from the best regression model developed, while the weights of each variable were computed based on magnitude of regression coefficient for each indicator. The level of reforestation success index was initially developed using six indicators, i.e. diversity index, nutrient retention index, colonization index, wildlife index, and environmental index. Of those indicators, the study found that the best key indicator for reforestation monitoring was canopy index which is composed of canopy stratification, crown cover and number of tree.

Judul: Evaluasi Tingkat Keberhasilan Revegetasi Lahan Bekas Tambang Nikel Di Pt Inco Tbk. Sorowako, Sulawesi Selatan
Abstrak: PT INCO has made a borrow and use agreement with the government to do mining activity in forest area. This mining activity has caused severe damage to the forest and the land. With full awareness and to fulfill obligation in borrow and use agreement, PT INCO has done rehabilitation to severely damage forest and lands due to its mining activity. An evaluation is needed to measure the succession rate of rehabilitation effort that has been done by PT INCO. This evaluation put an emphasis on vegetational and biological aspect, enabling to see how far the revegetation activity able to fulfill restoration purpose as mention in Permenhut Nomor 146/Kpts-II/1999 and to restore functions of a forest. Object of this research is forest stand resulted from revegetation planted in 1999-2007, 1985 and 1996. Some of the equipments been used in this activity are brunton compass, measuring band, Sunto clinometer, spherical densiometer, plastic rope. Vegetational analysis done by using 17,8 m diameter circle plot. For each planting year make 2-3 plots with range 50 - 100 meter between each plot, for some cases such as limited land one plot is sufficient enough. In it observation made to plant growth factor such as plant height, plant diameter, root development and crown covering. Another parameter that also observed are local species existances and wildlife presence. Growth percentage in revegetation area range from 95% to 100%. Plant composition are pioneer species as Sengon (Paraserianthes falcataria), Eukaliptus (Eucalytus eurograndis), Sengon Buto (Enterolobium macrocarpum)and local species as Trema (Melochia umbellata), Sandro (Sandoricum kacappeae) dan Uru (Elmerelia sp). This mean it is suitable with goverment rule. Root development, growth, litter decomposition, erotion and crown covering has shown improvement according to succession concept. Same thing happen to wildlife, introduction has happened to revegetation lands. Revegetation at PT INCO in some aspects has fulfill goverment´s criteria and indicator but this revegetation has not reform original forest structure and function as protected forest.
