Abstract

A better understanding of the spatial variability of soil nitrogen content is required to achieve the best management in precision agriculture. The purpose of this research was to determine the spatial variability of soil nitrogen content based on reliefs in an apple orchard. The research was conducted from March to August 2018 in a 1210 hectare of apple orchard, Batu, East Java Province, Indonesia. Soil samples were taken using the stratified random sampling method. Data were processed by the GLM Univariate 5% method with SPSS 16.0. The results of the statistical analysis show that the Sig value and coefficient of determination were 0.000 and 0.846, respectively. This condition means that soil nitrogen content was significantly different in various reliefs. The apple orchard was divided into 10 (ten) zones with different soil nitrogen content in various relief. It is crucial as a basis for implementing precision agriculture in apple orchards, meaning that the determination of fertilizer dosage is adjusted to the soil nitrogen content in the various zones. This study concluded that relief significantly affects the spatial variability of soil nitrogen content.

Abstract

Labile fraction plays a crucial role in maintaining soil fertility. Until recently, the information on the labile fraction of soil organic matter in dry lands with dry climates of Indonesia is very limited. Therefore, the experiment was conducted to study the changes of a labile fraction of soil organic matter in those drylands. The soil samples were obtained from 4 sub-districts (Kanatang, Haharu, Pandawai, and Matawai La Pawu) of Sumba Timur District. Those sub-districts have different altitudes, i.e. from 25 m – 900 m above sea level (asl). Soil samples were taken at 0-20 cm soil depth. Chemical analysis on soil pH, total N, organic C, and labile fractions analysis (water-soluble fraction, microbial biomass C, particulate organic matter, and microbial biomass N and water-soluble N) was done at The Plant and Soil Analytical Laboratory of ILETRI. The results indicated that altitude affected the availability of total N and organic C in soils. The higher the altitudes, the lower were N concentrations and conversely for the concentration of organic C and C:N ratio. Labile fraction N (water-soluble N and microbial biomass N) was reduced by increasing the altitudes. The ratio of labile fraction/organic C at altitudes >700 m asl was higher. This meant that the concentration of the active carbon pool was higher compared to that at altitudes <700 m asl. The ratio of MBC/SOC, as the indicator for the rate of biological activity, at altitudes >700 m asl was also high. The high value of MBC/SOC showed that the conversion of soil organic matter to microbial C was efficient.

Abstract

This study that was carried out in paddy fields on Paguyangan Highway in Paguyangan Village, Paguyangan District, Brebes Regency, was aimed to find out the effect of the road incline position, the distance between road and rice field toward the lead content and rice productivity. The study used a survey method namely purposive random sampling with two factors. The first factor was the incline position consisting of three slope levels, i.e. the beginning of the ramp (T1) with an altitude of 300 m above sea level (m asl), and a slope of 3.4º, the mid ramps (T2) with an altitude of 315 m asl and slope of 15.84º, and the end of the ramp (T3) with an altitude of 330 m asl and a slope of 8.7º. The second factor was the distance of sampling points from road i.e. 15 m (J1), 35 m (J2) and 55 m (J3). The measured variables were lead contents in rice and soil, as well as, the yield of rice. The results showed that the difference in incline position and distance between roads toward plants did not significantly affect lead content in rice, lead content the soil, and rice productivity on paddy fields around Paguyangan Highway, Paguyangan Village, Brebes Regency, although the lead contents in rice and in the soils were above the specified threshold.

Abstract

Rote Island is one of the islands in East Nusa Tenggara. In this island, land changes occur significantly. This land changes can be detected by Landsat images. These images are obtained from the big data engine. The big data engine used is the Google Earth Engine. This study aimed to detect land changes with harmonic modelling using multitemporal Landsat images from the big data engine. Harmonic modelling is used in monitoring changes in Normalized Difference Vegetation Index values in a multitemporal manner from Landsat images. Processing is done using the Geomatics approach. Land changes on Rote Island generally occur on coastal and savanna. Land changes on land generally have vertical deformation on its movement and horizontal on the savanna. The land changes accuracy result is 95% in 1,96σ. This method can be used for rapid mapping of land changes monitoring.

Abstract

This study aimed to evaluate changes in agronomic performances of some sweet potato cultivars planted in the rain-fed dry land and paddy fields. Completely randomized block design with three replications on a single factor of 12 sweet potato cultivars was done in two locations. The first location is the rain-fed dry land that formerly planted corn; located in Jatikerto, Kromengan District, and second is an irrigated paddy field that previously planted with rice, located in Wringinsongo, Tumpang District, Malang Regency. All cultivars that planted in both locations were applied to packaged standard cultivation technology for sweet potato. The parameters observed were storage root weight and vines weight (kg/plant), storage root yields and vines yield (t/ha), harvest index (%) and root/shoot ratio to describe the efficiency level of dry matter translocation to storage root. The results showed that there was a change of agronomic performance in sweet potato cultivars that planted between on the dry land and paddy fields, especially for storage root weight, storage root yield (t/ha) and root/shoot ratio. Changes in the sweet potato cultivation in the dry land to paddy fields are shown by an increase in storage root yields ranging from 2-4 times or reach 206 - 417%.

Abstract

Phytoremediation is one of the most effective and environmental-friendly methods in retrieving oil-contaminated soil. The decline of Total Petroleum Hydrocarbon (TPH) oil in the phytoremediation process will be accelerated by Oil Spill Dispersant (OSD) as a surfactant and the use of Ricinus communis L. plant. Commercial OSD products used in the remediation process are S200 OSD which contains LAS surfactant, which is a US EPA recommendation and is known to be less environmental-friendly, so SBRC-IPB develops OSD containing palm oil surfactants and is environmental-friendly. The purpose of this study was to determine the performance of OSD and R. communis to reduce TPH. This study used a completely randomized design with two factors, namely OSD and plant use. The results of this study indicated that OSD from SBRC-IPB improved plant growth, increased dry plant biomass, accelerated the decrease in TPH and increased the bacterial population compared to the S200 OSD and control. The combination of OSD from SBRC and R. communis was able to degrade TPH better than S200 OSD, with and without R. communis, with TPH concentrations of 30,000 ppm (3%) to 2,333 ppm (0.2%) for 20 weeks. This showed that the use of OSD was able to provide a positive response in the phytoremediation process of land contaminated with petroleum

Abstract

The role of tropical forests for maintaining environmental functions is decreasing due to the rapid changes to agricultural purposes. Agroforestry system is assumed to be an alternative system which reduces the negative impact of the conversion in term of maintaining the level of soil macrofauna diversity. This study was conducted at UB Forest within the period November 2017 to February 2018 by collecting soil macrofauna from 9 different land use types using hand sorting along with pitfall sampling for comparison. ANOVA and various diversity indexes were used (Shannon index, Pielu index, etc) to determine macrofauna structure and communities. Total soil C was examined using Walkley and Black method along with Particulate Organic Matter (POM) C fractionation approaches. Litter inputs were collected using a litter trap method, whilst in-situ litter were determined using destructive methods. Biplot and CVA multivariate analyses were adopted to determine the impact of different management on soil macrofauna diversity and structure. The result showed that conversion to agriculture practices reduced the structure, population and abundance of soil macrofauna as litter production, organic matter and soil C content decreased. The lowest abundance of individual soil macrofauna at monoculture system (PM) was reduced to 45 morphospecies compared to pine coffee agroforestry at the age of 4 (PK4:20 years after planting) system as much as 104 morphospecies. There was a strong relationship between litter thickness and the abundance of soil macrofauna. Both methods (Hand sorting vs Pitfalls traps), had a different ability for collecting soil macrofauna communities. Species occurs at rich or low organic matter input can be adopted as soil macrofauna bioindicator of changes on an ecosystem. Biplot and CVA methods can be used to distinguish and to cluster the impact of different management at various agroforestry systems.

Abstract

The objective of this research was to study the effect of bacterial isolates on red pepper at the saline condition. The research conducted in the station of Brawijaya University in Jatikerto village, Malang regency. The study used a randomized block design with bacteria isolated from the soil of saline-prone regions of Lamongan, in coastal East Java Indonesia. The treatments consisted of P0: saline soil without bacteria, P1: saline soil + bacteria SN 13, P2: saline + bacteria SN 22, P3: saline soil + bacteria SN 23, P4: saline soil + bacteria (SN 13 + SN 22), P5: saline soil + bacteria (SN 13 + SN 23), P6: saline soil + bacteria (SN 22 + SN 23), and P7: saline soil + bacterial (SN 13 + SN 22 + SN 23). Red chilli variety used was Gada MK F1. The results showed that the application of bacterial isolates increased leaf area, dry weight of roots and shoot. Uptake of N, P, K and Na also increased with bacterial isolate application. The number of fruit and fruit weight increased by 11.94% and 15.93%, respectively, compared with no bacteria. Proline content increased with the application of bacterial, while the capsaicin content decreased.

Abstract

Pollution of agricultural land by tailings from the Artisanal and Small-Scale Gold Mining (ASGM) can increase the concentration of mercury (Hg) in plant tissue thus; it will endanger the health of humans and animals that consume it. This study aimed to determine the amount of Hg taken up by maize plants on an inceptisol contaminated with tailings from amalgamation and cyanidation processes of small-scale gold mining. A field experiment was conducted at the experimental field of Faculty of Agriculture, University of Mataram by using a factorial randomized block design consisting of two factors, namely: (1) tailings (L), and (2) ) fertilization (N). The results indicated that adding amalgamation and cyanidation tailings increased the physical and chemical fertility of the soil studied but caused Hg pollution. Most of the Hg in plant tissue was concentrated in the roots of the plants. The content of Hg in the plant shoot was above the threshold value of mercury allowed in plants. The NK33 variety of maize can be categorized as a mercury tolerant plant as the plant grew well in a mercury-contaminated soil.

Abstract

Local cassava agro-processing industries in Nigeria generate toxic organic effluent with negative environmental impact if disposed without adequate treatment. This study examines the performance of a lab-scale aerated sequencing batch reactor (SBR) in degrading cassava mill effluent using palm kernel (Elaeis guineensis) shell (PKS) as biofilter media. Wastewater samples were collected before and after flowing through each compartment at hydraulic retention times of 3, 5 and 7 hours. Continuous aeration and nature-based degradation of the effluent recorded overall removal efficiencies of 73.5% (Hydrogen cyanide), 70.59% (BOD), 69.18% (COD), 29.93% (Turbidity), 4.92% (Sodium), 25% (Magnesium) and 14.32% (Calcium) respectively. Effluent electrical conductivity (EC) slightly increased by 7.84%. The Sodium Adsorption Ratio (SAR) of the treated wastewater ranged from 6.9 to 7.3 while the final pH ranged from 4.5 to 4.6. The values of EC, BOD and COD were significantly different (P<0.05) along the treatment sequence, confirming the effectiveness of the chambers in reducing these pollutants. Despite achieving high removal efficiencies, the final values of most parameters still fall short of the local permissible limit signifying operational limitations and the need to optimize the system to reduce key contaminants to safe disposal limits
