Abstract

Tin mining activities have been taking place in Bangka Island since early years ago. Impacts of mining operations are decrease in soil physical and chemical properties, changes in land topography, losses of natural vegetations, and diminishing wildlife habitat.  Ex-tin mining land is widely covered by the spread of tailings.  Tin tailings have poor physical and chemical characteristic, soil conditions and unfavourable micro-climate. To reuse ex-tin mining land, especially tailing land, reclaimation and rehabilitation programs be required.  Applications of various ameliorants and technology has been tested to obtain satisfactory results, particularly the addition of organic matters.  A number of specific local plant species including industrial forest tree such as acacia, and  some fruit tree species have been selected for ex-tin mining land revegetation.  In future, research in revegetation technique will be focused on usage of locally potential organic matter for tailing amendment and selection of some revegetation species which are more useful to increase social economic community.     Keywords : tin mining, tailing, revegetation, organic matter

Abstract

Sand tailings derived from tin post-minings activities have high porosity, low water holding capacity, and low organic matter content. These conditions causes soil water defi cit, especially in dry season. To increase the successful of sand tailings revegetation with rubber tree, it is important to select some rubber tree clones based on their adaptability on the sand tailings conditions, especially drought stress. This research aimed to study the response of several rubber tree clones to the frequency of watering on sand tailings. The experiment was conducted in a plastic house at the experimental station of Agrotechnology Study Program of Bangka Belitung University, Sungailiat for 4 months. The experimental design was a factorial randomized block design with two factors and three replications. The fi rst factor was the frequency of watering (every day, every 3 days, and every 5 days), the second factor was a combination of recommended rootstock clones and recommended latex clones (clone GT 1 + PB 260, GT 1 + IRR 118, and PB 260 + BPM 24). The results showed that watering every 5 days caused drought stress resulted in impaired growth of rubber in sand tailings media derived from tin post-mining. The combination of rootstocks and scions PB 260 + BPM 24 and PB 260 + IRR118 were categorized as moderately tolerant clones while GT 1 + PB 260 was categorized as sensitive clones to drought stress in the sand tailings media.Keywords: drought tolerance, watering frequency, rubber tree clones, sand tailings

Abstract

Biofertilizer is a fertilizer containing nine microbial consortia that useful for plant growth. The benefits of using biofertilizers are to improve fertilizer efficiency, maintain fertility soil and plant health, improving yield and sustainability. The aim of this research was to know the effect of the biofertilizer dosage to the population dynamics of microbial abundance of tin mined area planted with pepper plant (Piper nigrum L.). The method used is a direct observation method in the field through soil sampling with a purposive sampling technique. Six Soil samples were taken from every level of treatment. Soil samples were isolated, PDA media for fungi, NA media for bacteria and pikovskaya media for microbes solubilazition phosphate testing for both bacteria and fungi consisting of 54 plates. Result of the research indicate that different dosage of biofertilizers did not affect the dynamics of micro-organisms abundance. Treatment of B4 (10 g L-1 plant-1) gave a good effect on the abundance of fungi. While the treatment of B3 (5 g L-1 plant-1) gave a good effect on bacterial abundance. The result of nitrogen-fixing test was obtained by N inhibiting bacteria on NFB media in the presence of a pellicle at the bottom of the test tube. The result of the phosphate solubilization test was obtained with clear zones surrounded bacteria and fungi. Analyzed six soil samples contained nitrogen-fixing bacteria and Bacillus cereus with bacteria as phosphate solubilization bacteria.
