Abstract

Cajuput oil production process in PMKP Sukun produce cajuput oil and waste. There are three types of waste generated, ie liquid waste, solid waste, and gas waste. Solid waste in the form of waste of cajuput leaves is mostly used for briquettes and sold crude and the remaining is unutilized. To reduce the very high volume, so the unutilized solid waste is used as added fertilizer to planting media of cajuput seedling. This study was conducted to determine the effect of treatment of leaves waste compost of cajuput oil (bokashi) on the growth of seedlings of cajuput plants (Melaleuca cajuputi Powell). The method used was a randomized block design consisting of nine treatments and three replications with the observation parameters of seedling height, number of leaves, dry weight, soil pH, organic C, N, P, K, and N absorption. Results of the study showed that bokasi fertilizer 1 at a dose of 167 g polybag-1 gave the highest cajuput seedlings, and bokashi fertilizers 3 with a dose of 167 g polybag-1 gave the highest  number of cajuput seedling leaves.

Abstract

The water content of the soil in Jatikerto is 32,02%. As it is supported by clayey loam soil texture, the soil is able to absorb more water, but the water in the soil cannot necessarily be available to the plants. One effort to maintain the availability of ground water can be done with the soil amendments materials such as biochar. This study used three types of biochar, i.e. rice husk, coconut shell, and wood with each contained three doses (15, 30 and 45 t ha-1). This study used ten treatments with two factors consisted of types and doses of biochar. Soil sampling was conducted at 2 points on the array and on an array, and each point was conducted on soil depth of 0-20 cm and 20-40 cm. The variables measured were soil texture, soil bulk density, soil porosity, pore space distribution, pore fast drainage, pore slow drainage and pores water available. The results indicated that treatments of types and doses of biochar did not change the texture of the soil. The highest soil bulk density contained in biochar types of wood biochar dose of 30 t ha-1 (1,20 g cm-3), while for soil particle density was not significantly influenced by the biochar treatments. The average value of the highest porosity was measured on the type of wood biochar dose 15 t ha-1 (47,54% vol). The highest pore fast drainage contained in biochar types of coconut shell biochar dose of 30 t ha-1 (20,80% vol), while for the highest available pore water was on the type of coconut shell biochar dose 45 t ha-1(21,55% vol). The highest pore slow drainage was on the type of wood biochar dose 30 t ha-1 (29,03% vol).

Abstract

Entisols are soils with low organic matter and sandy texture. Soil with this characteristics generally have problems in the provision of nutrients for plants, especially of N due to the high nutrient leaching process. One effort that can be done in addressing the issue is with the addition of inorganic fertilizer and organic fertilizer. Inorganic fertilizers which contain N and frequently encountered is urea. Cow urine and waste compost tea are liquid organic fertilizers which have the potential to be developed as rich elements of N, P, K that are needed by plants. The purposes of this study were to determine the influence of urea and liquid organic fertilizer for crop N uptake and production of mustard (Brassica juncea L), and to determine the optimum dose of urea and liquid organic fertilizer for the production of mustard on Entisols. The results showed that the application of urea and liquid organic fertilizers significantly affected N uptake in mustard. Dose combination of 50% Urea (0.22 g polybag-1) and 50% liquid organic fertilizier (110.91 mL polybag-1) resulted in the highest N uptake value 15.81 g plant-1 compared to the control treatment of 3.11 g plant-1 and resulted in an increase in the height, number of leaves leaf area, fresh weight as well as the mustard dry weight, respectively for 74.88%; 80.00%; 353.95%; 177.40%; 104.73%. Dose combination of 50% Urea (0.22 g polybag-1) and 50% organic liquid fertilizier (110.91 mL polybag-1) was the most effective dose of fertilizier to meet the needs of N in mustard

Abstract

Gold processing tailings in small-scale gold mine in the form of sludge that still contain Hg and various other metal elements are commonly discharged in agricultural land and water bodies. The discharge of the tailings at Sekotong of West has inhibited growth and yield of maize in the area. The purpose of this study was to explore the potential of Lindernia crustacea for phytoremediation of soil contaminated with small-scale gold mine tailings containing mercury. Lindernia crustacea was grown on the mixture of top soil and (70% weight) and 30% (by weight) of amalgamation or cyanidation tailings for 8 weeks. To enhance uptake of mercury, ammonium thiosulphate was added with doses of 4 and 8 g kg-1 to the planting media when the plant reached 6 weeks old. The results showed that the addition of 4 g and 8 g ammonium thiosulphate increased the accumulation of Hg in the plant shoot by 61% and 27 %, respective, compared to the treatment without addition of ligand. The addition of 4 g and 8 g ammonium thiosulphate also increased 15% and 11% accumulation of Hg, respectively, in the plant root compared to the treatment without addition of ligand. Based on BCF, BAF and TR values, it was known that with or without addition of ammonium thiosulphate, Lindernia crustacean is suitable for use in pytostabilization activities

Abstract

Phosphate is the second essential chemical element for plants. However, it mostly presents in insoluble form. Using biofertilizers containing phosphate-solubilizing bacteria can increase phosphate solubilization. However, it is often ineffective due to the high temperature of the storage warehouse so the viability and enzyme activity of the microbes can decrease. The aims of this study were to determine the optimum and maximum temperature of phosphate-solubilizing bacteria’s viability, knowing the effect of storage temperature on the bacteria population and halozone of phosphate-solubilizing bacteria, knowing phosphatase activity of phosphate-solubilizing bacteria which were incubated at high temperatures, and knowing the organic acid production of phosphate-solubilizing bacteria which incubated at high temperature. The results showed that 37˚C was the optimum temperature of JBNO6, KT6D, KT7D and EPS5 strains and they could hold the high temperature of 58˚C (thermophilic). The ability of all strains in dissolving the P-insoluble decreased at high temperatures. However, the enzyme activity would go back again at room temperature (reversible). The acid phosphatase value of all phosphate-solubilizing bacteria strains was higher than the alkaline phosphatase value in the entire storage temperature. At high temperatures, KT6D was capable of producing oxalic acid and KT7D was able to produce acetic acid. EPS5 was the highest in the ability of phosphate solubilizing, the ability to produce the phosphatase enzyme and the bacteria population compared with JBNO6, KT6D and KT7D.

Abstract

Sandy soil has many macro pores that can cause water and soil nutrients difficult to remain at top soil because of leaching. This study was aimed to elucidate the effects of application of biochar, sugarcane boiler ash, and cattle manure on nitrogen leaching and availability in a sandy soil of Asembagus, Situbondo. Treatments tested were without soil amendment (control soil), 10 t biochar ha-1, 10 t sugarcane boiler ash ha-1, 10 t of cattle manure ha-1, combination of 5 t biochar ha-1 + 5 t cattle manure ha-1, and combination of 5 t sugarcane boiler ash ha-1 +  5 t cattle manure ha-1.  The six treatments were arranged in a completely randomized design with three replicates. Measurement of leachate was carried out every two week for ten weeks after incubation. The results showed that application of 10 t biochar ha-1 decreased leaching of total nitrogen with more stable than the other treatments. Leaching of total nitrogen in application 10 t biochar ha-1 always decreased at 2 week until 10 week after incubation with the value of 0.10 – 0.29 ppm. On the other treatments and control, the leaching of total nitrogen has a value 0.07-0.77ppm and 0.18 – 1.08 ppm, respectively. The percentage of leachate volume in application of 10 t biochar ha-1 was lower than the control soil and the other treatments with values ranging from 51.45 to 82.46%.

Abstract

Intensive soil tillage without returning crop residues resulted in deterioration of physical properties, particularly soil water retention and soul penetration resistance, of dry land acid soils. One of efforts to overcome the impact of intensive soil tillage is implementation of conservation tillage. This study was aimed to determine the effects of the application of conservation tillage on soil penetration resistance and water retention on acid dry land of East Lampung. The treatments tested were conventional soil tillage (OT1), conventional soil tillage with application of 6 t maize residue ha-1 (OT2), soil tillage in row with application of 6 t maize residue ha-1 (OT3), and no soil tillage with application of 6 t maize residue ha-1(OT4). Parameters measured were soil organic matter content, soil bulk density, total pore space, water retention, soil penetration, and biomass of soybean. The results showed that OT4 treatment (no tillage with application of 6 t maize residue ha-1) had the lowest penetration resistance of 1.75 Mpa and highest water retention capabilities 10.42% compared with conventional tillage

Abstract

Inceptisols are young soils that have undergone further development are characterized by low nitrogen content, low organic matter contend, and low pH. Fertilizer application is therefore needed to improve fertility of the soils. Tea waste that is easily found at home or factories can be used as organic fertilizer to supply nutrient elements in the soil. The purpose of this study was to elucidate the influence of application of combined compost (mixture of tea waste, cow dung and goat dung) on N uptake by leek plant (Allium fistulosum L.). Eight treatments (control, 5%, 25%, 50%, 75%, 100%, 125%, and 150% compost) were arranged in a completely randomized design with three replicates. The results showed that application of combined compost of tea waste, cow dung and goat dung significantly affected soil pH, soil organic carbon, soil total N, N uptake by plant, plant growth and plant yield. The highest N uptake by plant was observed for treatment 100% compost application (9.1 t ha-1) that yielding 114.62 mg plant-1, while the lowest N uptake was found on the control treatment that yielding only 54.98 mg plant-1.
