Abstract

Nurfitriani et al, 2019. Mercury Accumulation Ability of Bacteria Isolated from Small-Scale Gold Mine Tailing. pp. 366-375. Heavy metal pollution in the soil due to small-scale gold mining activities (ASGM) is responsible for 37% of mercury (Hg) pollution to the environment in the form of tailings . This pollution causes mercury enrichment  in agricultural land and crops above the safe limits. This study aimed to isolate heterotrophic bacteria which can  accumulate mercury from small-scale gold minetailings in Sekotong District, West Lombok. In this study, mercury resistant bacteria were obtained through a series of on Nutrient Agar medium. The obtained isolates were identified based on the colony morphology (the Bergey Manual Determinative system), gram staining test, biochemical test and growth curve test. Hg accumulation ability test was carried out on liquid Nutrient Broth (NB) medium containing 50 mL + HgCl2( 10 ppm, 20 ppm, and 30 ppm). The ability of isolates to accumulate Hg was also tested on gold mine tailings with an incubation method for 4 weeks. The results showed that four isolates of mercury-resistant bacteria were isolated, namely Brevundimonasvesicularis, Nitrococcusmobilis, Fusobacterium aquatile, and Fusobacterium necrogenes. Two of four isolates obtained, Fusobacterium aquatile and Brevundimonasvesicularis, could accumulate Hg highest in tailing medium.Brevundimonasvesicularis had the highest Hg accumulation ability which was approximately 1.68, 2.08, and 2.17 ppm Hg at 10, 20, and 30 ppm Hg treatment, respectively. Based on this study, Fusobacterium aquatile and Brevundimonasvesicularis have the potential to be used in bioremediation of soil contaminated with mercury.

Abstract

The effect of mixing of Tithonia diversifolia pruning which decomposes and mineralizes rapidly and Lantana camara pruning which decomposes and mineralizes slowly on rates of decomposition and mineralization of the prunings to improve synchronization between P released from the prunings with crop demand for P was studied in a laboratory and in a glasshaouse. Tithonia diversifolia pruning (Td), Lantana camara pruning (Lc), and farmyard manure (Pk) were thoroughly mixed with the proportion (% of dry weight) of : 25Td+75Lc; 50Td+50Lc; 75Td+25Lc; 90Lc+10Pk; 45Td+45Lc+10Pk; 100Td and 100Lc, and than mixed with 100 g of air-dried soil with a rate equivalent to 100 kg P/ha. Results of the study showed that the pruning mixtures decomposed and mineralized faster than that of Lantana camara pruning only, but slower than that of Tithonia diversifolia pruning only. The amount of P released from the mixtures increased with increasing proportion of Tithonia diversifolia pruning in the mixtures. Increasing proportion of Tithonia diversifolia pruning in the mixture applied to the soil increased the amount of P taken up by maize

Abstract

The agricultural sector is the mainstay of the economy in Central Moluccas. However, most agricultural soils on the island have low soil fertility. One of the efforts that farmers can make to improve soil fertility is to apply organic matter, which is widely found in Central Moluccas. This study aimed at elucidating the effect of mixing high-quality organic material (Glicidia sepium pruning) with low-quality organic material (sago pulp waste) on the improvement of available nitrogen in an acid soil (Dystrudept) and growth of maize. Two experiments were carried out in a laboratory and a greenhouse. The compositions of the mixtures of sago pulp waste (A) and pruning of Gliricidia sepium (G) were A0 G100; A20G80; A40G60; A60G40; A80G20, and A100G0. Six treatments and one control (no application of residues) were arranged in a completely randomized design. The results showed that the application of the mixture of 20% and 80% of Gliricidia sepium pruning (A20G80) increased the cumulative amount of mineral N in the soil higher than that of the other organic material mixtures, which in turn improved maize growth.

Abstract

Produksi nanas mengalami penurunan. Rendahnya produksi nanas diakibatkan karena rendahnya hara tersedia. Oleh karena itu untuk meningkatkan ketersediaan hara dalam tanah perlu dilakukan penambahan kompos kotoran sapi. Namun bahan baku dari kompos kotoran sapi sangatlah sedikit. Sehingga perlu dilakukan penambahan limbah cair nanas yang diharapkan mampu meningkatkan keterdiaan hara dalam tanah. Penelitian ini dilakukan di PT. Great Giant Pineapple. Penelitian ini dilakukan pada bulan November 2017 hingga bulan Mei 2018. Penelitian ini dilakukan dengan Rancangan Acak Lengkap dengan 5 perlakuan. Masing-masing perlakuan dilakukan ulangan sebanyak 3 kali ulangan. Perlakuan dari penelitian ini antara lain K0 (0 t ha-1 Kompos Kotoran Sapi + 0 L ha-1 Limbah Cair Nanas), K1(Pemupukan SBT (Standar Budidaya Tanam Nanas menggunakan pupuk kimia), K3L1 (20 t ha-1 Kompos Kotoran Sapi + 10.000 L ha-1 Limbah Cair Nanas), K3L2 (20 t ha-1 Kompos Kotoran Sapi + 15.000 L ha-1 Limbah Cair Nanas) dan K3L3 (20 t ha-1 Kompos Kotoran Sapi + 20.000 L ha-1 Limbah Cair Nanas). Berdasarkan hasil penelitian menunjukkan bahwa pemberian kompos kotoran sapi 20 t ha-1 dan limbah cair nanas 20.000 L ha-1 memiliki ketersediaan hara tanah lebih tinggi dibandingkan dengan perlakuan lainnya setelah dilakukan penanaman tanaman nanas di 60 HST (Hari Setelah Tanam). Sehingga pemberian limbah cair nanas mampu meningkatkan ketersediaan hara dalam tanah dan dapat memberikan substrat bagi mikroorganisme untuk proses dekomposisi bahan organik.

Abstract

Small-scale gold mining activities in Sekotong District of West Lombok Regency started in 2009. Gold is recovered through a two-stage process of amalgamation and cyanidation. Tailing is discharged to land with no concern for contaminants. Phytoremediation could cost-effectively replace traditional mercury remediation strategies. The objective of this study was to elucidate the potential of Cyperus kyllingia Endl for phytoremediation of soil contaminated with mercury of gold amalgamation and cyanidation tailings in conjunction with ammonium thiosulphate to phytoextract mercury. The study was conducted at the Laboratory of Soil Brawijaya University and in a shade house located in the area of ​​Dermo, Sengkaling. Samples of tailings-uncontaminated soil were mixed with samples of tailings with the proportion of 30%: 70% (w/w). At harvest shoots and roots were analyzed for mercury concentration in treatments, Tailing (tailings cyanidation and amalgamation), ligand ( 0, 4, and 8 g/kg ). The results showed that Cyperus kyllingia was a potential local species for phytoremediation of mercury contaminated soils as this plant was able to take up mercury of 122,53 mg/kg (shoot) and 77,9 mg/kg (shoot). Based on TF (translocation factor) value that was < 1, it is a potential species for phytostabilization. Addition on 8 g ammonium thiosulphate / kg planting media enhanced mercury taken up by plant as much as 71,18%. Key words: mercury , phytoremediation, ligand

Abstract

Forest conversion for plantation and the continuous fertilizer usage without organic materials has potentials to produce soil damage with the soil compaction. One of efforts to improve sustainable land productivity is by applying organic materials. The use of organic materials of vermicompost, fruit peel fertilizer, and cow manure in long term is expected to be able to improve the physical properties of soil at the robusta coffee plantation (Coffea canephora  Pierre). The research was conducted at robusta coffee plantation of PT Perkebunan Nusantara XII (Persero), Bangelan Village, Wonosari District, Malang Regency. The research used factorial random design of nested pattern with 2 factors: (1) organic material treatment (control, vermicompost, coffee fruit peel fertilizer, and cow manure),  (2) the soil depth level (0-10 cm, 10-20 cm, and 20-30 cm. The results showed that application of vermicompos improved higher organic matter than the application of coffee peel fertilizer, cow manure in depth of 0-10 cm. The application of various organic materials did not improve the organic materials of soil in depth of 10-20 and 20-30 cm. The application of vermicompost, coffee peel fertilizer and cow manure improved aggregate stability than without the application of organic material (NPK). Organic materials had a positive relation with soil aggregate stability in depth of 0-10 cm (r = 61%), so the higher organic material content, the higher soil aggregate stability, while in depth of 10-20 cm and 20-30 cm there was no significant relationship

Abstract

Andisols have low phosporus availability because of amorphous (non-crystalline) of high allophane. This problem may be overcome by application of organic materials and utilization of phosphate solubilizing microbes such as Aspergillus niger. This fungi can facilitate phosphate bound Al and Fe to soluble and available to plants. The objective of this study were to explore the influence of Aspergillus niger and chicken broiler manure on the avaibility and P uptake by maize at grown on an Andisol. This study used a simple randomized design with six treatments, i.e. PK1 (control), PK2 (3.5 t ha-1 chicken broiler manure + 10 mL Aspergillus niger with the density is 109 propagul mL-1, PK3 (3.5 t ha-1 chicken broiler manure + 20 mL Aspergillus niger with the density is 109 propagul mL-1), PK4 (3.5 t ha-1 chicken broiler manure + 30 mL Aspergillus niger with the density is 109 propagul mL-1), PK5 (3.5 t ha-1 chicken broiler manure + 40 mL Aspergillus niger with the density is 109 propagul mL-1), PK6 (3.5 t ha-1 chicken broiler manure + 50 mL Aspergillus niger with the density is 109 propagul mL-1), with three replicates. Results of this study showed that chicken broiler manure and Aspergillus niger could increase P-availability and P-uptake by maize in an Andisol. The most effectives dose of Aspergillus niger was 50 mL with density 109 propagul mL-1..

Abstract

Alfisol is a soil having problems related to low pH, organic C and nutrient availability. Application of organic fertilizer may increase nutrient availability and plant growth. The purposes of this study were to determine the effect of the decomposition rate of liquid organic fertilizer of tofu waste to N and S on the soil, and to determine the effect of the decomposition rate of liquid organic fertilizer of tofu waste on uptake N and S in maize. This study used a completely randomized design with nine treatments and three replications. The results showed significant effects of the application liquid organic fertilizer of tofu waste on the pH, C-organic, total N, plant height, and leaf number. Application of liquid organic fertilizer of tofu waste previously decomposed for two days (P2 treatment) showed the best results at the beginning and end of the analysis. The total N at the P2 treatment increased 50% compared to the control treatment in the beginning of soil analysis and 23.51% in the end of the soil analysis. Application of liquid organic fertilizer of tofu waste gave no significant effect on N and S uptake by maize. Application of liquid organic fertilizer of tofu waste previously decomposed for twelve days (P7 treatment) gave the best results with an increase in N uptake by 107.62% compared to the control treatment.
