Abstract

Productivity of agricultural land in coastal area is limited by salinity. Planting tolerant variety combined with amelioration is an effective management to increase productivity of salt affected land. The objective of this study was to identify effective ameliorant for improving growth and yield of groundnut on saline soil. The trial was conducted on saline soil in Tuban from May to September 2015. The trial consisted of two factors that were arranged in a completely randomized block design, three replications. The first factor was two groundnut varieties (Domba and Hypoma 1). The second factor was six soil ameliorations (control, 120 kg/ha K2O, 2.5 t/ha dolomite, 2,5 t/ha of gypsum, 2.5 t/ha of manure, and 1.5 t/ha of gypsum + 2.5 t/ha of manure). Results showed that Domba and Hypoma 1 varieties could tolerate and completed their life cycle at insitu saline condition. Hypoma 1 was more prospective to be developed in saline condition associated with higher survival as well as better pod setting and seed development than Domba. Combination of gypsum and manure provided better effect than other treatments in improving saline soil, since it reduced exchangeable Na, Na saturation, and EC of soil, and also improved groundnut yield.

Abstract

The article is devoted to the task today to improve the effectiveness of blasting during construction of horizontal and inclined mine excavations. Construction of new and reconstruction of existing mines requires large volume of excavation works, which length can reach tens of kilometers for only one project. Drilling and blasting workings allow not only to break out rocks from a frontal part of an excavation, but also cause an internal effect, which can lead to undesired damage that, in turn, often lead to increased expenses for excavation operations and safety problems for personnel. Calculation methods for blasting and explosion operations is a topical issue in mining industry as they allow to improve characteristics of excavation works and safety of explosion operations. Dozens of scientists offer their design, which reflects the vision of the problem and its solution. There are many methods for calculating the parameters of drilling and blasting, but so far not developed a uniform methodology of calculation, which would encompass all the factors and explained the mechanism of formation of cracks around the explosive charge and the process of breaking rock. The paper presents a novel methodology for calculations for blasting and explosion operations. That methodology comprises various specifics of rock geology and mining engineering during works in horizontal and vertical excavations. In this paper given an algorithm for calculation two main areas of destruction: crushed zone and fracturing zone. In addition, article outlines main aspects of Mining Engineering Development from Antiquity until present days and presents the dynamic of mineral resources.

Abstract

Microbial decomposers are living things posessing an important role in outlining materials derived from organic compounds entering the environment as plant nutrients so that they arereusable by the greenery. This study was aimed to isolate and identify types of microbial decomposers from Palu local cow manure of Central Sulawesi, Indonesia. The results showed that in Palu local cow manure there were three types of microbial decomposers namely Lactobacillus sp, Actinomycetessp and Aspergillus sp. In Actinomycetes sp., the colony growth was very slow and firmly attached to the media surface after incubated for 7 days. It showed formation of mycelium spreading on the media surface with a serrated edge. Aspergillus sp.had morphological characteristics formed on media as follows: green-yellowcolonies; like-furtextures; green conidia; radiatconidia arrangement, uniseriat, fialidwhich almostfilled the entiresurface of vesicles; like-ballroundvesicle; coarse, thick-walled, and dark greenconidiophores.

Abstract

The purpose of this study was to determine the hydroseeding mulch optimum compositions for germination and productivity of a few species of local plants pioneer in the post-mining land of coal from South Kalimantan. The method used in this research was by hydroseeding technique. The species observed were Crotalaria pallida, Cajanus cajan, Kyllinga monocephala, Paspalum conjugatum, Digitaria sanguinalis and Eleusine indica. Seven variations of mulch were added to the post-mining soil. Planting seeds carried out were monoculture and polyculture. Each composition of mulch was replicated three times resulting in 147 pots. Seed germination was observed  for 15 days. The results showed that all species were able to germinate and and grow well in the mulch that was added to the post-mining soil, except Kyllinga monocephala on mulch two, four and five and Digitaria sanguinalis on mulch four. The best mulch for plant growth was characterized by pH of 6.8-7.0, 47-59% organic matter, and energy ranging from 2,337.68 to 3,792.68 Kcal/kg. The highest percentage of germination was observed for Cajanus cajan (56.7%) and Crotalaria pallida (39.4%) on mulch two with germination time of eight and three days after planting. The lowest germination percentage was shown by Kyllinga monocephala at all mulch treatments (up to 30 days after planting). The optimum composition of mulch that could be recommended to accelerate the revegetation was mulch two (pH 7.06 and 59% organic matter), especially for Leguminosae, and mulch seven (pH 6.8 and 47% organic matter), especially for Poaceae and polyculture.

Abstract

Studies on volcanic ash of Mount Merapi erupted in 2010 are limited to only characterization of mineralogical, physical, chemical, and biological properties of the volcanic ash. In order to speed up rehabilitation of soils affected by the volcanic ash, it is necessary to study the application of suitable plant species, which is called bio-mechanic conservation. The purpose of this study was to test the environmental adaptability of Canavalia virosa and Flemingia congesta in sandy soil covered by volcanic ash of Mount Merapi. This study was carried out using 2x4 Split-plot randomized block design with three replicates. The main plot of the design was plant species (Canavalia virosa and Flemingia congesta), while the sub plot was the dose of organic matter application (0, 20, 40, and 60 t / ha). Soil parameters measured were N-total, P-total, available P, available K, and organic matter contents. Plant parameters measured were plant dry weight and plant height. The results showed no significant differences in soil N, P and K contents of all treatments tested in this study after 9 weeks, except C organic content. Canavalia virosa grew well until 9 weeks, whereas Flemingia congesta started to die a 9 weeks after planting.

Abstract

The abundance of crops waste in the agricultural field can be converted to organic fertilizer throughout the process of composting or pyrolysis to return back into the soil. The study aimed to elucidate the effect of compost and biochar application on the physical properties and productivity of upland rice at Village of Sukaraja Nuban, Batanghari Nuban Sub district, East Lampung Regency in 2015. The amendment treatments were A. control; B. 10 t rice husk biochar/ ha; C. 10 t maize cob biochar/ha; D. 10 t straw compost/ha; E. 10 t stover compost/ha, F. 10 t rice husk biochar/ha + 10 t straw compost/ha; F. 10 t maize cob biochar/ha + 10 t maize stover compost/ha. The treatments were arranged in randomized block design with four replicates. The plot size for each treatment was 10 x 20 m. After incubation for about one month, undisturbed soil samples were taken using copper ring at 10–20 cm depth for laboratory analyzes. Analyses of soil physical properties included bulk density, particle density, total porosity, drainage porosity, and soil water condition. Plant observations conducted at harvest were plant height, number of panicle, number of grain/panicle, and grain weight/plot. Results of the study showed that biochar and compost improved soil physical properties such as bulk density, total porosity, fast drainage pores, water content, and permeability of soil. The combination of rice husk biochar and straw compost gave better effect than single applications on rice production components (numbers of panicle and grains of rice), and gave the highest yield of 4.875 t/ha.

Abstract

Soil moisture stress in coffee plant impacts on the productivity of coffee fruit at PT. Perkebunan Nusantara XII, it is because the low ability of the soil to store water. The ability of the soil to store water can be increased by increasing the organic matter content of soil, especially humic substances. Soil organic matter plays an important role in the improvement of soil physical properties, especially the availability of soil moisture for plants. The purpose of this study was to analyze several humification parameters at four age of plantations plots of coffee and its relation to the water distribution potensial on Inceptisol PT. Perkebunan Nusantara XII Malang district. The research was conducted at PT. Perkebunan Nusantara XII were taken soil samples from 8, 28, 40, and 80 years old robusta coffee plots at 0-30 cm and 30-60 cm soil depth. The results showed that the increasing the age of the coffee plantations significantly increased the input of organic matter in the soil, with indicators of increased litter on soil surface, increased levels of soil C-organic and N-total, humic acid and soil pH. Increasing age of coffee plantations until 80 years did not affect to the value of humification parameters (C/N ratio, HA/FA ratio, E4/E6 ratio, and the humification rate (HR)). The age of coffee plantations affected the total acidity, carboxylic groups and phenolic OH, where the values tended to decrease with the  older of coffee plantations in the 0-30 cm of soil layers and increased in 30-60 cm. Increasing age of coffee plantations improved the total pores and available water content in the 0-30 cm of soil layer.

Abstract

Rice productivity is having a problem related with climate change phenomenon, mainly the global warming. The rising of temperature in some country threat the rice production. The increasing of temperature is a major limiting factor that affects yield through the growth and development of rice plant. This study was aimed to examine the response of rice (Oryza sativa L.) to elevated night temperature with the application of Pyraclostobin. A glasshouse experiment that was conducted from March to August 2015 at Brawijaya University Research Station of Jatikerto – Malang, used nested plot design with three replications and two treatments. The first treatments were the night temperature level (normal temperature, increased 2oC, and increased 4oC). The second treatments were the concentration of Pyraclostrobin (0 ppm, 400 ppm and 800 ppm). Results of the study showed that the increase of temperature at night for about 2oC and 4oC, as well as application of Pyraclostrobin, affected growth and yield of rice. Application of Pyraclostrobin by concentrations of 400 ppm and 800 ppm effectively reduced yield loss by increasing night temperature of 2oC, which resulted in 20.20% and 24.93%, respectively, in comparison with the control; while the increase of night temperature by 4oC have resulted 26.86% and 33.33% in comparison with the control. Pyraclostrobin was effective in maintaining percentage of the filled spikelets by the increase of temperature at night for about 2oC and 4oC.
