Abstract

A field experiment to elucidate the effect of tillage systems and dosages of cow manure on weed and soybeans yield (Glycine max, Merrill) was conducted at the Agrotechno Park of the University of Brawijaya in Jatikerto, Malang, from May to July 2017. The experiment used a split-plot design with 3 replications. The main plot was the tillage systems, with 3 levels: T0= No-tillage, T1= Minimum tillage, and T2 = Conventional tillage. The subplot was the dosages of cow manure, with 3 levels: P1= 2.5 t cow manure/ha, P2 = 5 t cow manure/ha, and P3 = 7.5 t cow manure/ha. Results of experiment showed that dry weight of weed was higher at no-tillage systems and at dosages of 7.5 t cow manure/ha. Growth and yield of soybean were lower at no-tillage compared with conventional tillage systems. Application of cow manure with dosages of 5 t/ha and 7.5 t/ha was better than 2.5 t/ha for growth and yield of soybean.

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

One of the main technological tasks facing mining engineers today is a reduction of the oversized fraction output. Currently, the efforts of scientists are aimed atdeveloping reliable grain-size composition predicting models for the extracting rock mass, as one of the initial factors for reducing economic losses throughout the technological cycle. However, many of the existing models do not consider the mutual influence of a number of factors, which explains the instability of the drilling and blasting performance indicators, their low efficiency and, as a result, an increased oversized fraction output. The model for grain-size composition predicting for mining enterprises will be interesting only if the proposed technological solution together with a pre-established fraction of rock mass will increase the efficiency of blasting operations with the desired reduction of all material and non-material expenditures. In this paper the authors give a brief overview of the global mining volumes; provides information on the extraction of key types of minerals, as well as revenues derived from their sale. They also specify the direction for future actions in creating a predicting model for the rock mass output of a certain fragmentation after the explosion.

Abstract

Nutrient loss in dry land through surface runoff and soil erosion is thought to dominate the watershed eutrophication. Conservation agriculture is expected to be able to reduce the nitrogen (N) loss into river systems. This study aimed to compare the N total input between conservation and conventional farming systems and to analyze N losses through surface runoff and soil erosion in conservation agriculture compared to conventional farming systems. The study was conducted at Agro-Techno-Park at Jatikerto, Brawijaya University from December 2017 to September 2018. The experiment was designed with three factors, i.e. (1) with and without biogeotextile, (2) No and conventional tillage, (3) application of four kinds of cover crop residues, with three replications. Results of the study showed that conservation agriculture was able to provide higher N inputs into the soil than conventional agriculture. The N loss through surface runoff was relatively low, ranging from 0.03 kg/ha to 0.45 kg/ha. N loss through erosion with conventional tillage and without biogeotextile reached 15 kg/ha to 32 kg/ha. No-tillage practices combined with the biogeotextile application significantly reduce N losses through soil erosion to only 0.3 kg/ha to 5 kg/ha. Conservation agriculture is one of the solutions to overcome the trade-off between the need for increased food production and environmental protection.

Abstract

Indonesia has an abundant amount of basalt rocks resources, including in East Lampung Regency of Lampung Province. This basalt has not been used optimally and only be used as a foundation. The use of basalt as soil fertilizer also known as the stone meal. This study focused on the effect of using basalt dust on the growth and development of organic fertilizer application for the cassava plant. This study is to support the local government policies that declared Lampung as a national development centre of cassava, with a production rate of 30.8% of the national production of cassava. Basalt powder was characterized using test petrograph and X-ray Fluorescence (XRF) for a description of microscopic and chemical composition. The test results were used to determine the chemical composition of rock classification using the TAS diagram. The experiments of applying fertilizer on cassava crops in the demonstration plots 8 treatment x 3 repetitions were conducted by adding the percentage by weight of the basalt towards organic fertilizer between 0% (control 1), 10%, 20%, 30%, 40%, 50%, 60%, and without treatment (control 2). The results indicated that basalt from East Lampung is classified as olivine Tholeite basalt which is rich in CaO, Mg and Na2O + K2O. The growth rate of cassava plants which are affected by basalt powder presentation is characterized by a value which is higher than the value of CGR control, and recommended to not exceed 10% of the weight of basalt fertilizer.

Abstract

This review paper aims to review on the causes and consequences of land degradation in Ethiopia. The results from different literatures indicate that the major factors that cause land degradation in Ethiopia are: clearing woodland for agriculture , repeated cultivation, removal of residuals and dungs, single cropping, extraction of wood, , population growth, deforestation, soil erosion, low technology, inadequate extension services, political instability, cultivation on steep slopes, overgrazing, traditional way of cultivation, heavy wind, high intensity of rainfall, drought and landslides, absence of all-inclusive land use and lack of land use plans developed. On the other hand, the depletion of forests and vegetation, loss in water resources, decrease in the quality and quantity of livestock, enhancing the unemployment rate and out-migration, conflict between pastoralists, food insecurity, deceasing of soil fertility and arable land, reduction of agricultural productivity, increasing price of farm inputs, reduction of plants grown, depletion of aquifers, loss of biodiversity, reduction of potable water, shortages of timber, climate change and desertification are the major consequences of land degradation in Ethiopia. Afforestation, Reforestation, terracing, crop rotation, mixed cropping, irrigation schemes and traditional soil conservations are among the coping strategies that Ethiopian farmers are using. To overcome this problem, strengthening the teamwork among policy makers, GOs/NGOs, local communities, research institutes and the mass media are the key agents that must take these responsibilities.

Abstract

Local cassava processing industries produce large quantities of wastewater containing cyanide which is toxic in nature with negative impacts on the environment when disposed without treatment. In this study calcined periwinkle shell (CPS) was prepared, characterized and used to adsorb cyanide present in cassava wastewater. Equilibrium studies were conducted in batch set ups to investigate the influence of process variables such as adsorbent dosage, pH, temperature, contact time and initial cyanide concentration on the adsorption process. The highest removal rate of cyanide from cassava wastewater was found to be 78.34% with equilibrium reached at fixed adsorbent dosage of 3.0 g at contact time of 80 minutes. Cyanide adsorption was also observed to be dependent on pH with the maximum adsorption of cyanide occurring at a pH 10. The percentage of cyanide removed decreased with increase in cyanide concentration. Results from the study confirm calcined periwinkle shell as low cost and effective adsorbent which can be used for the removal of cyanide from cassava wastewater

Abstract

Pyroclastic materials from Mount Kelud eruption which deposited in surrounding areas has very low nutrient availability. Fertilizer efficiency is normally low due to a coarse texture. This research was an attempt to increase nutrient availability using zeolite and organic matter in combination with inorganic fertilizers. The materials was treated with three rates of inorganic fertilizers (100%, 70%; 40% of the recommended rates, i.e. Urea 400 kg/ha; SP-36 150 kg/ha, and KCl 75 kg/ha), in combination with three types of amendments (zeolite, Tithonia diversifolia leaves, and cow manure at the rate of 20 t/ha), and 100% inorganic fertilizer treated materials as control, and incubated for 60 days. Soil samples were taken every 10 days after incubation and analysed for soil pH, C-organic, available N, P, K content measurement. The results showed that total N content increased with the rates of inorganic fertilizers. At 10-20 days after incubation the content of NH4+ is greater than NO3- but gradually changed after 30 days after incubation. Apparently, zeolite treated materials had lower NH4+ content than organic treated samples at 10-20 days after incubation, however at 60 days after incubation its NO3- content was relatively higher than Tithonia leaves treated samples. At 60 days after incubation, the higher the fertilizer rates, the higher the content of available P and exchangeable K. The highest content of available P and exchangeable K occurred respectively in cow manure and Tithonia diversifolia leaves treated materials. Until 60 days after incubation, organic treated materials had a higher amount of available and exchangeable K than zeolite treated materials, because they originally contain considerable P and K. However, at 60 days after incubation, zeolite treated materials contained the highest amount of NO3-. This indicated that zeolite had a higher capability to retain mineral N, hindering N removal from leaching and volatilization. A higher nutrient holding capacity could be related to the increasing cation exchange capacity after the addition of amendments, and to a lesser extend to pH and % C.
