Abstract

Almost all developing countries satisfy their energy requirements from firewood. In Ethiopia majority of the rural population relies on biomass energy sources for every energy necessities. Fuelwood accounts for about 78 % of the total energy needs, whereas animal dung and crop residue share 12 % and nine percent, respectively. Almost all of the firewoods are collected from natural forests and few of them from homestead trees. Chronic drought, land degradation, and loss of soil fertility that are positively correlated with low livestock and crop productivity are extensions of deforestation for firewood. Heavy dependency on biomass fuel in Ethiopia has resulted in fast deforestation, desertification, climate change, global warming and finally decrease in agricultural productivity. Therefore the adoption of biogas technologies has great potentials to supply low-cost energy and results in less dependency on firewood. To improve such adverse socio-economic and ecological costs, interventions like improved biogas technologies, raising community awareness on deforestation, and utilization of alternative energy technologies are recommended to conserve natural forests.

Abstract

Coal mining is an activity to exploit land to get coal stored underground. Environmental problems in coal mining activities are generally associated with Acid Mine Drainage (AMD). The purpose of this study was to find out the best combination of organic matter and incubation time in remediating acid mine drainage on wetlands with water hyacinth plants. This research was conducted at PT Berau Coal in Tanjung Redeb, Berau, East Kalimantan. This study used a split-plot design. The main plot was the treatment of a combination of organic matter which consisted of 4 levels: A0 as a control (without organic matter), A1 with a combination of compost + sawdust (1:2), A2 with a combination of compost + sawdust (1:1), A3 with a combination of compost + sawdust (2:1). The subplot was treatment incubation time consisting of 2 levels, namely for 15 days and 33 days. Data analysis used variance analysis at the 5% level followed by the Duncan Multiple Range Test with a level of 5% when there were significant differences. The results showed that the addition of organic matter had a significant effect on the increase in pH and a decrease in the concentration of Mn in water, but it did not significantly affect the decrease in Fe concentration in water. The best combination of organic matter in acid mine remediation in this study was compost + sawdust (2:1) during the incubation time of 33 days

Abstract

Biofertilizer production in Indonesia should fulfil the minimum requirement for being produced and released to the market. Problems occurred when those products are being absent on informing those expiration dates and the viability of microbial activity which then closely related to the quality of the product. Seaweed composted material are potential resources for producing Biofertilizer, but lacking on the optimization on their process as this material contain a various important component for soil and environment. The production of Biofertilizer from seaweed waste required an optimum condition, i.e.: pH and typical microbe which could germinate under specific formulation and temperature. This study aimed to determine the optimum pH in liquid fertilizer formulations made from seaweed waste in the form of composted material, to test the viability of three bacterial isolates and those pathogenicity properties, to examine the effect of metabolites release from bacterial isolates to green bean seed germination. The experimental design used was a completely randomized design with four treatments, which were as follow: P0 as a control (Peptone), RP1 (seaweed waste), RP2 (seaweed waste and glycerol), and RP3 (seaweed waste and PEG). The three bacterial isolates used were: (1) Bacillus licheniformis, (2) Psudomonas plecoglossicida and (3) Pantoea ananatis. This liquid fertilizer biological formulation was stored for 8 weeks at pH 5.5 and temperature 25oC. The results showed that the treatment of RP1 (seaweed waste) had high bacterial viability and could stimulate growth for green bean sprouts. The carrier material for seaweed waste with the addition of glycerol and PEG showed no effect of the disease and symptoms of a pathogenic bacterial consortium on germination of green beans.

Abstract

Bajo starfruit is a wild plant that commonly grows in nickel mining areas and it is known to have the ability to take up Ni metal from the soil, even though its Ni uptake ability is still relatively low. The objective of this study was to explore the effect of the application of citric acid and NPK fertilizer on the ability of Bajo starfruit plant in phytoextraction of Ni from post nickel mining land. Citric acid as a ligand is expected to enhance the availability of Ni in the soil so that Ni uptake by plants increases, while NPK fertilizer is expected to enhance crop biomass production. The treatments tested were combinations of four doses of citric acid (0, 1, 2 and 3 g of citric acid/kg of soil) with two doses of NPK fertilizer (0, and 1.33 g/kg of soil). Eight treatments were arranged in a factorial randomized block design with four replications. The results showed that the application of NPK fertilizer without citric acid increased the number of leaves and dry weight of plants. After the growth of Bajo starfruit for 25 weeks, the application of 3 g citric acid/kg of soil without application of NPK fertilizer reduced the total soil Ni from 8926 ppm to 2400 ppm i.e.73.11%.  Application of 2 g citric acid/kg of soil and 1.33 g NPK fertilizer/kg of soil resulted in Ni uptake by 118.18 mg/plant or increased by 38.61% compared to control. Application of 2 g citric acid/kg of soil without application of NPK fertilizer increased the BCF value of Bajo starfruit for nickel from 0.032 (control) to 0.035. However, treatments without the application of citric acid and fertilizer resulted in a higher TF value (13.9).

Abstract

Casuarina junghuhniana or mountain ru, she oak or cemara is a species from Indonesia which grows in the highland area at an altitude between 2000 - 3000 m above sea level (asl). One of the highland area in Eastern Java (Jawa Timur) of Indonesia is Bromo Tengger Semeru National Park (TNBTS). The study site was on the Tengger Sea of Sands, Eastern Java, Indonesia where it is affected by volcanic activity. This tree, from some references, has not been well studied yet although it has been reported as a tree native to Indonesia. The lack of the study poses problems when there is a program related to planting the tree on a certain location in TNBTS for rehabilitation purposes. This study attempted to construct a Structural Equation Model that mapped some factors observed in the study site related to C. junghuhniana population. Explored factors for their relationship with each other included the number of male and female individuals, growth-related indicators, and environmental factors consisting of altitude and the tree population. Formative factors which consist of parameters related to growth, environmental factors and factor associated with the diffusion of new individuals, may contribute to population growth while population growth was the opposite. The individual growth might not significantly contribute to the population of C. junghuhniana; instead, the population growth was affected by the tree individuals. Generative reproduction contributed the least to the dispersal as it may rely more on vegetative reproduction by adventitious shoots from roots.

Abstract

Land-use change and lack of conservation in Bogowonto Watershed area have caused land degradation due to erosion and landslides. The rate of land degradation can be measured through the morphological characteristics of the soil and landscape. This study aimed to identify the relationship between the morphological characteristics of the soil and the rate of land degradation in Bogowonto Watershed area. The research framework initiated from the interpretation of thematic maps, surveys and field observations, and verification using land degradation assessment software. Sample points were determined using a stratified random sampling method. In general, land degradation is affected by slope, limited soil development, suboptimal conservation measures, and land-use change. Particularly, land degradation is affected by the type of landscape and the morphological characteristics of the soil. Volcanic hilly landscapes show a degradation rate of fine to very fine, characterized by thick soil depth (>60 cm), generous root distribution, loamy textured soil, fine soil particle size (Ø <0.002 mm), and good soil structure. The distribution of easily weathered volcanic ash causes volcanic hills to have thick and fertile soil characteristics. Quaternary-tertiary volcanic transition landscapes show a degradation rate of damaged to heavily damaged, characterized by thin soil depth (<60 cm), limited rooting, dominant coarse fraction (Ø 2–0.05 mm), and contact with fields lithological discontinuity. The data obtained provide information on the morphological characteristics of the soil and land degradation in Bogowonto Watershed area. The results of the study can also be used as a formulation for the conservation of Bogowonto Watershed area.

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

Pawan and Jelai Rivers are two of the three main rivers in Ketapang Regency, West Kalimantan. The extensive growth of palm oil industry in Ketapang might affect the aquatic environment, especially the rivers, due to excessive uses of water. Therefore, the aims of this study were to examine the effect of palm oil industry on the changes in water quality status of Pawan and Jelai Rivers in Ketapang regency during 2012-2016 and to identify critical parameters that might determine the water quality status in the two rivers. This study used the laboratory testing results of Pawan and Jelai Rivers, which were carried out periodically by various companies/institutions. There were 24 physical, chemical, and microbiological parameters that were analyzed to determine the water quality status using STORET method. Critical parameters were determined by comparing parameters analyzed with their threshold values. The results revealed that Pawan and Jelai Rivers passing through oil palm plantations and palm oil mills were moderately to highly polluted in 2012, 2014 and 2016. Critical parameters of the river water quality are BOD, COD, Cl2, phenol, Fe, and total Coliform.

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%.
