Abstract

Artisanal Small Scale Gold Mining (ASGM) in Jampang Kulon produces tailing waste that contains heavy metals harmful to the environment. The taining, however, still contains gold metal (Au). Phytomining can be a solution in environmentally friendly gold mining by planting hyperakumulator plants on tailings and then extract its biomass. To increase the accumulation of gold in plant biomass, fertilizer is needed to enhance plants growth and chelate is necessary to increase the solubility of Au. This research aimed to know the effect of ammonium thiosulphate and compost on Au accumulation in vetiver grass (Vetiveria zizanioides L.) grown on tailings. This research used a completely randomized design with two factors, the dose of compost ; T0 (2.5 kg polybag-1), T1 (1.25 kg polybag-1), T2 (0 kg polybag-1) and the dose of ammonium thiosulphate ; K0 (0 g kg-1), K1 (5 g kg-1), K2 (10 g kg-1). The results showed that the addition of 10 g ammonium thiosulphate kg-1 significantly increased the accumulation of Au by 46% in plant roots and 35% in plant shoot related to control. While the addition of 1.25 kg compost polybag-1 could increase the accumulation of Au by 39% in plant roots.

Abstract

The purpose of this study was to elucidate the effect of composting on changes in soil physical properties and to examine the relationship of soil physics properties with plant growth. The method used is a completely randomized block design implemented on the moor land located in the Village Lojejer Wuluhan District, East Java Jember. The study was conducted on 750 m2 of land with an altitude of 14 above sea level. Type of soil that is found in the research field is an Inceptisol having organic material content of 1.1%. Parameters measured aggregate stability, soil pore, bulk density, organic hatter, plant height, leaf number, wet weight of plant, and dry weight of plant. The results showed that addition of several doses of compost improved physical properties of the soil studied. The addition of compost increased the amount of microbes in the soil that played as soil adhesive agents that make the stabile soil aggregate. The soil aggregates stability could increase pores and decrease the weight of the soil content. Composting did not affect the growth of plants because at the time of vegetative growth compost did significantly effect soil physical characteristics.

Abstract

The problem of Entisol used for agricultural land is the loss of nutrients due to leaching and evaporation. It is thus necessary to keep the nutrients available in the soil. The purpose from this research was (1) to know the effectiveness of Crotalaria juncea compost application on the availability of N, P, and K on Entisol Wajak, and (2) to assess the effectiveness of Crotalaria juncea compost application on uptake of N, P, K and growth of sweet corn in an Entisol of Wajak, Malang. This research used a completely randomized design with five treatments and three replications, i.e. C0 (Urea 100%), C1 (Crotalaria juncea compost 100% + Urea 75%), C2 (Crotalaria juncea compost 100% + Urea 75%), C3 (Crotalaria juncea compost 100%), C4 (Crotalaria juncea compost 200%). The results showed that application of Crotalaria juncea compost 100% (10 t ha-1) did not significantly affect available-P but it significantly increased available-N at 4 and 8 weeks with the effectiveness of 39% and 79.66%, and significantly increased the available-K at 8 and 12 weeks with effectiveness of 38.75% and 33.33% compared to 100% urea application (288 kg ha-1). Applications of 100% Crotalaria juncea compost (10 t ha-1) did not significantly affect plant growth (dry weight and plant height) as well as the N and K uptake, but increased the effectiveness of the P uptake 2.07% compared to 100% urea application (288 kg ha-1).

Abstract

Nitrogen is a macro nutrient need by plants to enhance growth and productivity. Nitrogen element can be supplied through inorganic fertilizer, compost or biological fertilizer. The purpose of this study was to analyze the effect of vinasse compost and endophyte bacteria of Klebsiella sp. on nitrogen uptake and sugarcane growth. The treatments tested in this study were K0 = control (no compost vinasse and Klebsiella sp.), P1 = (Klebsiella sp. + 75% ZA + 25% vinasse compost), P2 (Klebsiella sp. + 50% ZA + 50% vinasse compost), P3 (Klebsiella sp. + 100% ZA fertilizer + 0% vinasse compost), P4 (without inoculation of Klebsiella sp. + 75% ZA + 25% vinasse compost), P5 (without inoculation of Klebsiella sp. + 50% ZA + 50% Vinasse compost). The treatments were arranged in a completely randomized design with five replicates. The results showed that endophyte bacteria could only enter in P1 treatment. The total N-content, N-available and N-absorption were associated with P1 treatment. Vegetative growth of sugarcane did not show significant different. The P1 treatment had the highest value of plant height and number of leaves. As for the number of tillers, on 4 terms, the highest value was observed on P2 treatment.

Abstract

The development of forest plantations into one of forestry enterprises is seen as an activity that can reduce emissions by increasing carbon stocks. Measurement of carbon stocks needs to be done to obtain data of carbon stocks stored in a field so that it can be calculated emissions that are released into the atmosphere when there is a fraction of the land cover. In this study, carbon stocks was calculated by estimation method using allometric equations that had been made in previous studies and devoted to the stands of teak (Tectona grandis Linn. F), litter and soil. The study was conducted by dividing the teak plantation with various age classes (KU) of teak plant, ranging from KU 1 to KU 6. KU 1 has age 1 - 10 years, KU 2 has age 11-20 years, KU 3 has age 21 - 30 years old, KU 4 has age 31 - 40 years old, KU 5 has age 41-50 years and KU 6 has age 51 - 60 years old. The value of carbon stocks in the teak stands in each equation increased with the increasing age of the teak stand. Carbon deposits in teak forests increased by 3.96 t ha-1 to 5.54 t ha-1 annually. Teak forests can reduce CO2 in the air, and the greater the age of teak the greater CO2 in the air can be reduced. Teak forests can reduce CO2 in the air by 14.45 t ha-1 to 20.26 t ha-1 annually. Basal area value on teak stands affects 64% of litter biomass values. The higher the basal area value the litter biomass value will increase. Basal area values of teak forests in KU 1 to KU 6 ranged from 5.63 m² ha-1 to 50.36 m² ha-1.
