Illegal artisanal gold mining in Kebunlado, Riau Province has damaged the smallholders estate. The use of mercury for extracting the gold is potentially pollute the soil and syrrounding water as well as threats plantation productivity and it’s food chain. The purpose of this research is to study the mining impact towards the physical and chemical properties of the soil around the plantation, and measure the mercury contamination within the tailings, soil and river to be compared with the soil sample near the mine area. Sampling was carried out in 10 locations to study the properties of the land surrounding the artisanal gold mining. Physical and chemical properties of the soil were studied.The samples came from the mine sites (7 samples) and its surrounding area (3 samples). Sampling was conducted using a toposequence transect method, based on its topographical conditions and soil parent material with the purposive method. Mercury level was measured from eight soil samples that were sampled from surrounding artisanal mine area and six water samples from the surrounding rivers. The research showed that the soil characteristics had changed after mining activities. The soil properties were higher in sand, with bulk density and permeability compared to intact soil. However, there was no distinct change in pH, total nitrogen, organic carbon as well as available P, except C/N in post mine area was relatively low. Mercury content in the gold mine area was higher than that of the average mercury within the soil around the world. The Mercury in the river stream exceeds the threshold based on Indonesia Regulation. The study suggested that land reclamation is needed to develop oil palm plantation in terms of improving the soil physics, increasing C/N and remediation as well as reducing the mercury in soil and water.

Gold mine tailing in Buru island, Maluku Province, Indonesia contains high level of mercury but low in carbon and plant nutrients. Revegetation in such condition needs certain soil treatment which is suitable for plant growth. The objective of pot trials was to study the effect of indigenous Plant Growth Promoting Rhizobacteria Azotobacter and organic matter on bacterial survival as well as growth of groundnut grown in mine tailing. The experimental design was a Split Plot Design which tested three types of Azotobacter liquid inoculant and three soil total organic carbon (TOC) contents. Results showed that Azotobacter inoculation increased Azotobacter population in tailing at the end of vegetative growth of groundnut. Total nitrogen content in soil decreased when TOC level increased. However, nitrogen uptake and growth of groundnut did not change after Azotobacter inoculation or manure amendment. These experiments provided information that Azotobacter inoculation on groundnut maintain its proliferation in Hg-contaminated mine tailing.

Plant Growth Promoting Rhizobacteria Pseudomonas and Bacillus are well known biofertilizer due to their ability for solubilizing inorganic phosphate and producing phytohormones in soil. However, their potential to decreased diseases incidence caused by Pratylenchus coffeae has been documented. The objective of this laboratory experiment was to formulate solid biofertilizer contained Pseudomonas diminuta and Bacillus subtilis. The laboratory experiments consisted of three-step experiment: 1) selection of the molasses-based liquid media for P. diminuta and B. subtilis growth, 2) organic liquid inoculant formulation and 3) organic carrier-based inoculant formulation. The population of both bacteria in all steps was count by serial dilution plate method with specific medium. The result verifeid that cell density of P. diminuta and B. subtilis in liquid culture with 2% molasses were higher than cell count in the culture contained 4% molasses. Bagasse-based carrier inoculated with liquid culture of mixed bacteria has higher bacterial count compared to manure-based carrier. After 90-day incubation, bagasse-based solid inoculant maintained P. diminuta and B. subtilis density up to 108 CFU/mL and the acidity of solid inculaant was about neutral. The bacterial count and acidity of solid inoculant agreed with Indonesian standard for solid biofertilizer

Karst formations in Selasari and Parakanmanggu Village of Parigi District, Pangandaran Regency, West Java includes dolines, subterranean stream, springs, and karst hills are useful for agriculture. The purpose of this study was to 1) identifiy the used of karst area for rice cultivation and local trees in karst area; 2) evaluate the benefit of rice cultivation and local tree for local communities and 3) asses the legal aspect for supporting food crop production. The study was done using qualitative-descriptive method with the primary data obtained from field observations, soil analysis, local tree identification, and interviews. Secondary data was obtained from the Regional Government and the National Geological Agency. The results showed that rice cultivation has been carried out in suitable soil by using simple and rainfed irrigation. Local fruit, herbs, timber and shade-ornamental tree grow naturally on the karst area. Tree logging without significant revegetation caused water supply shortage so that farmers only grow rice once a year. Athough the rice productivity of both villages is lower than average rice productivity of Pangandaran Regency, rice is important to support local inhabitant’s consumption and family income. Land Use Plan year 2018 regulates the general provisions on zoning regulations for agriculture in susceptible area but the regulation does not mention the karst areas. This study suggested that tree conservation is needed to maintain the existence of rice fields. Land use planning for agriculture in the region must be based on integrated considerations of rice cultivation and local tree conservation.

Ultisol is low fertility soil and as low available P due to P fixation by Al and Fe. The phosphate solubilizing microbes (PSM) is the microbial group that enable realease fixed-P to soil solution and be absorbed by plant. This research was aimed to determine the effects of PSM biofertilizer and phosphate fertilizer dosage combination on soil potential P, total phosphate solubilizing bacteria (PSB) population and yield of maize (Zea mays L.) grown in Ultisols. This research used a Randomized Block Design that consist of nine treatments with three replications. The treatments were 100 kg ha-1 of SP-36 fertilizer, 50 kg ha-1 of PSM biofertilizer, SP-36 fertilizer (50 kg ha-1 and 100 kg ha-1) with PSM biofertilizer (25 kg ha-1, 50 kg ha-1 and 75 kg ha-1) repectively. The result showed that the combination of PSM and phosphate fertilizer dosage had significantly effect on PSB total population and maize yield, but did not not on potential P. This experiment suggested that SP-36 fertilizer with 50 kg ha-1 dosage and PSM biofertilizer with 50 kg ha-1 dosage is the best combination.

Potatoes (Solanum tuberosum L.) which are comonly grown in the highland with Andisols require organic and inorganic fertilizers to maintain soil health and increase yield. The purpose of field experiment was to obtain information on the effect of vermicompost with and without NPK fertilizer on soil acidity, soil phosphor (P) availability and P uptake in potatoes shoot; as well as yield and quality of tuber. The experimental design was a randomized block design with eight treatments and three replication. The treatment consisted of a combination of vermicompost doses (5 and 10 t/ha) with NPK fertilizer doses (0; 0.5 t/ha and 1 t/ha). The two control treatments were 1) without fertilizer and 2) the method of fertilizing local farmers included 10 t /ha chicken manure and 1 t/ha NPK fertilizer. This experiment verified that vermicompost and NPK fertilizer increased plant height as well as soil P availability and acidity compared to those of control. Vermicompost has not yet substitute chicken manure to obtain the same tuber production although the percentage of marketable tuber was quite similar. Keywords : Andisols, NPK Fertilizer, Phosphorus, Potato, Vermicompost.

The growth of nutmeg seeds requires adequate nutrition by mechanism of bacteria activity associated with roots and leaves. The aim of study was to determine the effect of application of bacillus strain consortium biofertilizer on nutmeg seedlings. The experiment was arranged by using completely randomized design with 0% of PBH as control, and 0.15% and 0,30% of PBH concentration by spraying to leaves and by pouring in the soil around the stem, respectivelly. The results showed that the application of 0.15% and 0.30% of PBH concentration has significant effect in plant height, shoot dry weight, dry weight root and plant dry weight, but not at the number of root, root length, stem diameter, and the ratio of shoot and root dry weight of nutmeg seedlings after four month planting in the polybag. The concentration of PBH 0.30% has a greater influence on the nutmeg seed growth, and can be a solution to increasee seed growth.

The spore-forming Bacillus and cysts forming Azotobacter are Plant Growth Promoting Rhizobacteria which has been used as biofertilizer in sustainable agriculture since they tolerant to dried soil. Drought resistant microbes will be useful to coat urea in order to reduce the lost of nitrogen. The objectives of this preliminary study were to study the effect of molasse based liquid media on the population of Bacillus spore and Azotobacter vegetative cell and to determine the composition of four bacterial species in liquid formula. In the first experiment The Bacillus subtilis, B. megaterium, A. chroococcum and A. vinelandii were grown separately in 1% cane molasses enriched with 0.1% NH4Cl. As control treatment, The Bacillus and Azotobacter were grown in Nutrient Broth and Ashby’s mannitol broth respectively. In the second experiment, different composition of said Bacillus and Azotobacter were grown in molasses based liquid media prior to count the spore and vegetative cell. The results showed that molasses-based media supported bacterial growth and initial ratio 1:1:1:1 of liquid inoculant was effective to increase bacterial growth. This experiment suggested that the use of organic based media was useful practice of liquid biofertilizer formulation for granule urea coating.
