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

This paper reviews the effects of habitat loss and human influence on the survival of Black-crowned cranes in Africa. Black-crowned crane is distributed through Sahel and Sudan Savannah regions of Africa, ranging from the Senegal basin and Guinea-Bissau drainage in West Africa to the western Ethiopian Highlands and south-west Rift Valley in East Africa. Habitat loss, transformation and degradation, and illegal capture and trade for pet industry, are the major threats of the species. Because of habitat loss, the population of Black-crowned cranes is declining across its home range and it is even disappearing in some countries in West Africa. It is predicted that the population decline will continue in the future due to habitat loss and trapping of cranes for domestication. The species is classified as Lower Risk from 1988 to 2000, Near Threatened from 2004 to 2008, and then Vulnerable from 2010 onwards. The rapid conversion of wetlands and intensive land use and different economic development with poor environmental protection threat the survival of Black-crowned cranes. In order to overcome the threats of Black-crowned cranes (Balearica pavonina), habitat conservation and community awareness are essential, not optional.

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

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

Forests are one of the most valuable ecosystems in the world, containing over 60% of the world’s biodiversity. This ecosystem has multiple social economic values, apart from its intrinsic value.  Forest provides a sustainable environment. Deforestation leads to the disappearance of sustainable development. Deforestation takes place due to multiple of reasons like logging, population growth, urbanization, grazing, construction of dams and reservoirs, habitat fragmentation, slash and burn method of farming, wildfire, global warming, hydroelectric projects. Agriculture is considered to be the backbone of the Ethiopian economy and almost 85% of the societies in Ethiopia engage in agriculture.  The agricultural sector in Ethiopia in particular and in Africa, in general, is highly affected by deforestation directly and indirectly. Therefore, this paper focuses not only on the causes and consequences of deforestation but also seeks for better alternatives to tackle deforestation in Ethiopia

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

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

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

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

Coastal areas are found in the dynamic zone at the interface between the three major natural systems of the Earth's surface. The phenomenon of shoreline change is one of the most frequent problems encountered in the coastal environment and is caused by natural processes that result in dynamic changes in the coastal area. Coastal area change can affect the vulnerability of the coastal environment and its properties, such as shoreline stabilization, flood control, sediment retention, natural protection and others. The method of integrating remote sensing data with geographic information system (GIS) techniques has been widely used to monitor and analyze the dynamics of shoreline change in coastal areas. The purpose of this study is to map and analyze the dynamics of shoreline change from 1978 to 2017 in the study area. An approach combining spectral value index and visual interpretation of Landsat images was used and proposed to indicate the separation of land and water bodies, for shoreline extraction. The normalized difference water index (NDWI) can be used as a spectral value index approach for differentiating land and water bodies. Furthermore, the analysis of shoreline changes was performed using the digital shoreline analysis system (DSAS). Based on calculations made using DSAS, it can be seen that the pattern of coastline change tends to be dominated by offshore erosion. The results of this study may also be important as input data for coastal hazard assessment as part of the effort to overcome the problem of flood tides.
