Abstract

Natural resource management is one of the primary needs of all living things, both for consumption and supporting other activities. Batu City, East Java Province, is a tourist area and a water catchment area that has the potential to be a source of ground water. However, the development of infrastructure as a espoused of tourist areas need serious undermining of the sustainability of the land water source. In 2001 the environmental carrying capacity ratio was 1.75 with a conditional safe status. In 2011 and 2015 the status of environmental carrying capacity has been exceeded with a ratio of 0.85 and 0.62. In 2017 there is a conditional safe status with an environmental carrying capacity ratio of 1.24.Keywords: Demand Water Resources, Ratio of carrying capacity, Supply water resources,

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

Ultisols are characterized by less aggregate stability, high clay, solid, organic material, and low pH. These can be managed by using calcification, augmentation of organic material and fertilization. One of soil amendments than can be used to improve properties of Ultisol is biochar.  The objective of this study was to elucidate the effects of cocoa's shell biochar application on soil aggregate stability and growth and yield of maize at an Ultisol. Treatments tested in this study were D0 (no biochar application), D5 (application of 5 t biochar ha-1), D10 (application of 10 t biochar ha-1), D15 (application of 15 t biochar ha-1), D25 (application of 25 t t biochar ha-1), dan D40 (application of 40 t biochar ha-1). The results showed that in one growing season giving some doses cocoa's shell biochar had not been able to affect soil aggregate stability. The highest aggregate stability was found at treatment of 15 t ha-1 of cocoa’s shell biochar with an index of 130.12. The increased levels of soil organic C was followed by the increase in aggregate stability index. The highest organic C was found at D40 treatment with 4,09%. While the highest retention of water was found at the D10 with 32,96%. The increased aggregate stability index was not followed by the ability of soil to retain water. The addition of cocoa's shell biochar could increase soil organic C but not in line with the ability to retain water. If cocoa's shell biochar was given at the hig dose then it can give high maize yield.

Abstract

Long term intensive tillage causes land degragation or damage soil physics and  affect on root growth and plant production. This research aimed to know the effect of tillage system and mulch aplication on soil physical properties, rooting, and green bean producton. The experiment was conducted in March - May 2016 in the village of Pendem, Junrejo District, Batu City. The study was conducted using a Randomized Block Design Factorial (RBDF) with two factor and each factor has 3 levels. The first factor is the tillage (T) and the second factor is the application of mulch (M), so that the total combination of the factors is 9 treatments. Each one is made of the plot and the treatment was repeated 3 times. The treatment are, no tillage (T0), minimum tillage(T1), intensive tillage (T2), without mulch (M0), silvery black plastic mulch (M1), and straw mulch (M2). The system of minimum tillage with straw mulch application is the best treatment of all combinations because it has the best value in bulk density, porosity total, roots, and the produce of green bean. The effect just occur on the short term, that is 14 days after planting, whereas after harvest (60 HST) there are not effected.

Abstract

Poor quality of agricultural soil is characterized by low soil organic matter (OM) content, high bulk density, low porosity, and low infiltration. One of efforts to improve soil quality is by adding OM from biomass prunings. Aim of this study was to test the effectiveness of adding OM to the increase of soil organic carbon (SOC) and its relationship with soil bulk density, porosity and infiltration. This study was conducted at Salak (Salacca zalacca Gaertner Voss) plantation owned by a smallholder farmer in Pasuruan District, East Java. Measurements were done at three different treatments of organic material and condition, i.e. at litter stackline (addition of OM), between the Salak plant (without OM addition) and pathway (farmer traffic line) on two age groups of Salak (10 and 20 years) with 3 replications. Soil samples were collected from three f soil profile depths, 00-10, 10-20 and 20-30 cm. Parameters measured were soil organic carbon content, bulk density, particle density, porosity and infiltration rate. Results showed that addition of organic matter from Salak biomass effectively increased the SOC content. However, the increase of SOC content only had positive effects on soil bulk density, porosity, and infiltration rate at the 10 years old group of Salak plantation.

Abstract

The condition of increasing the demand for sugar is not balanced with the production of sugarcane because the production from year to year fluctuates. Continuous inorganic fertilization in sugar cane causes a decrease in soil productivity. This study that was aimed to determine the potential of biological fertilizer as a provider of soil nutrients to reduce the use of inorganic fertilizers for sugarcane was conducted at Sugar Research Center PT. Perkebunan Nusantara X Kediri. This study consisted of planting stage of sugarcane plant, application of liquid combined biofertilizer and observation of vegetative growth of sugar cane plant, and soil nutrient analysis. This study used a randomized block design using seven treatments with four replications. The treatments tested were P0 (without biofertilizer + without NPK fertilizer), P1 (100% NPK fertilizer), P2 (biological fertilizer + 100% NPK fertilizer), P3 (biological fertilizer + 75% NPK fertilizer), P4 (biological fertilizer + 50 % NPK fertilizer), P5 (biological fertilizer + 25% NPK fertilizer), P6 (biological fertilizer). The results indicated that the presence of bacteria could increase the growth of sugarcane and soil nutrients content. The best growth of sugarcane plantation occurred at the treatment of P2 (biological fertilizer + 100% NPK fertilizer).This was suspected to occur because the nutrient needs of the plant could be met quickly by the presence of inorganic fertilizers as well as the help of nitrogen fixing bacteria and phosphate solubilizing bacteria in the biological fertilizer.

Abstract

The development of agriculture in dry land, is expected to contribute in the field of Indonesian agriculture. Dry land agriculture has some problem i.e. the low moisture content and drought. The drought that occurred in Gunungkidul, one of them. The purpose of this research was to evaluate the availability of water on some of the land use in each soil depth by using two approaches, namely evaluation of the evapotranspirasi and the characteristics of land, with the intend to present information about the relationship of some land use with the availability of water in dry land farming in Gunungkidul. Models were used to calculate evaporanspirasi and crop water needs, calculate the physical properties of the soil, and comparing the two calculations. The results of the analysis indicated that the availability of water in dry land farming in Gunungkidul Yogyakarta was influenced by the characteristics of the land (physical properties of the soil) 21,5% and the remainder was by other factors. The highest available water was on sugar cane plantation, 42,81% in 0-20 cm depth. The available water on forest land and teak product was 35,68% in 40-60 cm depth.

Abstract

The pollution of water and soil caused by human causes environmental damage especially on agricultural land that resulted in the reduced growth and yield of plants. This research aimed to understand the ability of aquatic plants in accumulating lead (Pb) in water and its influence on lettuce growth. The treatments consisted of A1: Plant Lemna minor 2 ppm Pb, A2: Ceratophyllum demersum 5 ppm Pb, A3: Lemna minor 2 ppm Pb, A4: Ceratophyllum demersum 5 ppm Pb, A5: 2 ppm Pb without plants (control 1), and A6: 5 ppm Pb without plants (control 2). The results showed that the aquatic plants effectively decreased Pb concentration in water by 81.1% for Ceratophyllum demersum and by 75.5% for Lemna minor. The use of remediated water for watering lettuce resulted in affected growth and yield of lettuce.
