Abstract

Sand mining is a natural resources exploitation. The effects of sand mining are environmental degradation and reduction of soil physical, chemical and biological quality. The land of ex-sand mining could be marginal land and constitutes a barrier for revegetation. Soil amendment is a necessary phase for overcoming this problem i.e. additional of sub soil and charcoal of coconut shell on the soil. Species selection also determines the success of revegetation. Jabon (Anthocephalus cadamba) is a pioneer, adaptive and fast growing species. The aims of this reasearch are to analyze the effects of sub soil and coconut shell charcoal addition on the growth of jabon seedlings on ex-sand mining soil, and to find out the optimum dose of sub soil and coconut shell charcoal addition. The results of this research showed that sub soil and coconut shell charcoal addition on ex-sand mining soil, increased the positive effect. The combination of 500 g of sub soil and 20 g of coconut shell charcoal gave the best growth for jabon seedling on ex-sand mining soil.Key words : Anthocephalus cadamba, charcoal, coconut shell, sand mining, sub soil.

Abstract

The resiliency of the ex-burnt forest area will following the forest succession stages and resulted to secondary forest. This study was conducted to identified: (1) type and cause of forest fire on September 2012 at Hutan Pendidikan Gunung Walat (HPGW), (2) differences of the vegetation composition of stands, (3) undergrowth succession, as well as (4) differences of soil chemical properties in the ex-burnt and unburnt stands. Fire in HPGW was mainly due to the careless use of fire by local communities when they used fire to burn thatch on their land. Highest index of similarity is found on tree stage at all plots, while the most significant differences found on undergrowth stage. This may related to the vulnerability of the undergrowth to evey changes that occur, one of which is the change on soil chemical properties. Generally, the soil chemical properties at 11th month after fire is better than 6th month after fire.Key word: composition of vegetation, forest fire, soil chemical properties, succession, undergrowth
