Abstract

The discharge of the upper Cijurey watershed (4.217 km2) was measured using an automatic water level recorder since 1999. The teak (Tectona grandis) plantations of different age classes cover the whole watershed. The watershed is dominated by undulating topography with gentle slopes, low soil permeability and also low potential aquifer flow rate.  Hydrograph analysis shows that high peak flow (Qp) reached 32,5 m3/s (1,3 m), while concentration time (Tc) and recession time (Tr) were 2 hours and 3 hours, respectively. Visual observations on stream flow shows that the maximum discharge was more than 2 m high, which caused flood, while for two successive months (August and September, 2000) the river at the watershed out let was totally dry. These hydrograph properties indicated the quite bad hydrological response of the watershed.

Abstract

Evaluation of land rehabilitation (revegetation) activities is necessary for measuring the extent of success of the ongoing activities in rehabilitating and recovering degraded lands. One way for evaluating the success of land rehabilitation (revegetation) is by determining the changes of micro enviroment. The objective of this research was to study the changes of micro environment in various types of revegetated land cover, including scrub/bush land (SB), agricultural land (TP), monoculture teak (JM) and mixed crops (TC) in Ciliwung upper watershed. Research results showed that the highest air temperature and soil temperature were obtained at SB, respectively at 32.8 °C and 26.5 °C, and the lowest at TC, respectively at 28.1 °C and 20.7 °C. Relative humidity and soil moisture were highest at TC (72.3% and 96%) and lowest at SB (60.8%), and the lowest soil moisture occurred at JM (45%). The highest infiltration rate occurred on TP (475.5 mm h-1, very rapid), followed by JM (117 mm h-1, fast) and TC (80 mm h-1), and the lowest at SB (17.65 mm h-1, medium slow). Erosion reductions occurred after 6 years of the revegetation activities with the following results:TC (96,676.1 ton year-1 ha-1), JM (10,790 ton year-1 ha-1), TP and SB (52,867.9 ton year-1 ha-1 and 24,612.6 ton year-1 ha-1). The micro environments for all land cover types were better after revegetation activities.

Abstract

Mining activities could have negative impacts on the environment if the tailings produced were not processedproperly. Non-economic tailing is a composite of various minerals (heavy metal) with sandy texture. Environmental impacts that might occur as a result of poor processing of tailings is a disruption of natural ecosystems as indicated by a decline in quality and productivity of the environment as a result of changes in soil morphology and physical properties, chemical, and biological properties. One vegetative technique that could be applied to rehabilitate degraded land is re-vegetation with the application of fertilizer. Compost could improve the physical properties, chemical, and biological properties of soil. Compost was also an agent of bioremediation so that toxic heavy metals elements in growing medium could be eliminated or reduced. The experimental design used in this study was Completely Randomized Design with compost applications consisting of 4 levels of treatment with each level of treatment consisting of 3 replications, each replication consisted of one gmelina seedling. Research showed that the application of compost would significantly affect the growth of gmelina’s height, but not significantly affected the diameter growth. Single-dose effect of 30 g of compost would significantly affect the seedling’s height. The combination of planting and fertilizing glemina using compost could be recommended in an effort to reclaim land of ex-gold mining.

Abstract

Destruction of the Gunung Leuser National Park area of North Sumatera Province through land clearing and land cover change from natural forest to agricultural land. Less attention to land use and ecosystem carrying capacity of the soil can cause soil degradation and destruction of flora, fauna, and wildlife habitat destruction. Environmental damage will result in a national park wild life will come out of the conservation area and would damage the agricultural community. Soil sampling conducted in purposive sampling in natural forest and agricultural areas. Observation suggest that damage to the natural forest vegetation has caused the soil is not protected so that erosion has occurred. Destruction of natural forest into agricultural are as has caused damage to soil physical properties, soil chemical properties, and biological soil properties significantly. Forms of soil degradation caused by the destruction of natural forests, which is an increase in soil density (density Limbak) by 103%, a decrease of 93% organic C and soil nitrogen decreased by 81%. The main factors causing soil degradation is the reduction of organic matter and soil erosion due to loss of natural forest vegetation. Criteria for soil degradation in Governance Regulation Number 150/2000 can be used to determine the extent of soil degradation in natural forest ecosystems.

Abstract

Agroforestry is an alternative land use that not only provides benefits in economic aspects, but also in ecological aspects including improving soil quality. This research aims to evaluate the physical quality of soil in various types of land use, including agroforestry systems and evaluate the efficiency of the VESS method in determining soil physical quality. This study uses the VESS method to analyze soil quality in six land uses in Pangalengan, West Java (i.e. agroforestry, forest, tea plantations, coffee plantations, agriculture cultivation, and abandoned land). It used The VESS method because it has been widely applied in many countries, but has never been applied in Indonesia. Soil property parameters (BD, soil porosity, soil permeability, and SOC) were measured to correlate with the VESS score. VESS score ranged from 1 (good soil quality) to 5 (poor soil quality). The VESS score for each land type ranged from Sq 1.3–4.33. The soil quality in agroforestry (Sq 1.89–2.04) is not much different from natural forest (Sq 1.3). The VESS score has strong correlation (r) with soil property parameters (BD = 0.97, soil porosity = -0.97, soil permeability = -0.83, SOC = -0.94). A Strong correlation value indicates that the VESS method can be used to analyze soil quality.
