The eruption of Mount Sinabung consistently and material issued increasingly large volume has caused plant and agricultural land damaged. Agricultural land damage was caused by the material issued mountain area is 10.945,24 ha. The role of technology and the results of research that has been done to agricultural lands caused the eruption of Mount Sinabung to be recommendations for the improvement of agricultural land. Efforts to improve the aspects of physical and chemical land are conservation, rehabilitation land of sand and the increase in the quality of the land. The thickness of volcanic ash after an eruption of covering agricultural land can be divided into 4 classes, namely: thin (the thickness < 2 cm), medium (thickness 2- 5 cm and thick (> 5 cm). Efforts for the recovery and rehabilitation land on each cluster based on the thickness of the dungeon ashes were normal processing with a hoe or plow, fertilizing with of organic matter and to the lava, dungeon needs to be done the conservation and land rehabilitation by an annual plant / the forest. The rehabilitation of agricultural land that badly damaged by eruption material may not be restored in a short time because of soil conditions which are acid, rocky and sandy. Thus the programs carried out by gradually and different treatment in accordance with their condition agricultural land.

AbstractThe paper is based on the hypothesis that coastal lakes significantly affect changes in the quality of freshwater coming from catchments, which is best reflected in the reduction of biogenic loads. Some of the main reasons for this phenomenon include unique geographic locations of coastal lakes and physical and chemical properties of their waters as well as other hydrographic determinants that affect water circulation in catchments. The study area covered the direct drainage basin of Lake Lebsko, which is located in Słowiński National Park in northern Poland, on the coast of the southern Baltic Sea. The study was conducted from June 2008 to October 2010. Fieldwork was the main part of the research project and included hydrographic mapping, water sampling for laboratory analysis, and measurement of the discharge in all tributaries and outflows of the studied lake. Water chemistry data for Lake Lebsko indicate a significant accumulation of biogenic materials in the lake, which proves a strong effect exerted by the lake on the incoming water. This is true for both total chemical loads per year as well as concentrations of selected ions over short time intervals. This standard pattern may be interrupted by seawater intrusions that alter water chemistry in the whole lake.

In 2013 Indonesia has developed Bandung Techno Park (BTP) as the business incubator and develop Startup Corner (SC) program. SC has four main phrases, such as Registration, Selection through Presentation, Pre Incubation, and Implementing Incubation Process. However, SC has not been maximized in identifying aspects of opportunities, teams and resources. The purpose of this research is to know the role of SC in developing in relation with opportunity, team, and resources aspects. This research used descriptive qualitative method, with Timmons Model approach. The sample of this research is SC members and BTP supervisor by using structural interview with informans. As the results, the role of SC on the dimension of idea has played for product development, business model, and selling price. Market demand dimension is directing customer translation so that can assist in reaching customer opportunity and expanding market reach. Furthermore the role of SC in developing startup of team aspect based on leader dimension and team quality. The SC through training program has purposed to shape the entrepreneurial character during Pre Incubation activities. In creating the quality of the team submitted by setting an advisable work discipline in accordance with the BTP working hours other than that Startup Corner helps in disseminating recruitment information for startup requiring members. The role of SC in developing startup from the aspect of resources has provided physical facilities, then assistance to make the legality of a business entity, patent but there is no funding for the sustainability of a startup, then diverted in incubation or other programs. SC arranges all the sections for startup participants and has a good results but the final maitenance would take effort from the startups itself, because BTP only supports them and building the business model in techonology in short time.

During the years 2001 and 2002 we conducted hydrochemical monitoring of intensively managed pond to evaluate the impact of high pig slurry doses on eutrophication. Pig slurry application was carried out in colder period of the year (February–April) via tube system with sludge pump from nearby piggery. Our results showed that pig slurry application do not permanently affect the water quality of Jarohněvický pond. When the correct application is made slurry is effectively utilized by biomass for the growth, which prevents surface and underground waters to be polluted as in the case of incorrect application on agricultural land.Critical point of this technology in terms of water management is the way of pig slurry application and the exact dose. Even extremely high slurry doses (16.1 kg . m−2 in 2001 and 15.6 kg . m−2 in 2002) used in Jarohněvický pond did not negatively affected pond ecosystem. Only higher amount of organisms that increased natural fish production was recorded. It is necessary to implement this ameliorative intervention in colder period of the year considering higher hazard of variations in decisive hydrochemical parameters at higher water temperature.

Abstract Dynamics of pesticides and their metabolites in drainage waters during baseflow periods and rainfall-runoff events (RREs) were studied from 2014 to 2016 at three small, tile-drained agricultural catchments in Bohemian-Moravian Highlands, Czech Republic. Drainage systems in this region are typically built in slopes with considerable proportion of drainage runoff originating outside the drained area itself. Continuous monitoring was performed by automated samplers, and the event hydrograph was separated using 18O and 2H isotopes and drainage water temperature. Results showed that drainage systems represent a significant source for pesticides leaching from agricultural land. Leaching of pesticide metabolites was mainly associated with baseflow and shallow interflow. Water from causal precipitation diluted their concentrations. The prerequisites for the leaching of parental compounds were a rainfall-runoff event occurring shortly after spraying, and the presence of event water in the runoff. When such situations happened consequently, pesticides concentrations in drainage water were high and the pesticide load reached several grams in a few hours. Presented results introduce new insights into the processes of pesticides movement in small, tile-drained catchments and emphasizes the need to incorporate drainage hydrology and flow-triggered sampling into monitoring programmes in larger catchments as well as in environment-conservation policy.

Although Thermal Analysis is a useful technique in characterizing the clay constituent of a potentially valuable clay deposit, it is, perhaps, even more useful when the type and amount of non-clay impurities are important factors in its commercial appraisal. The effect of impurities on the physical and chemical properties of the clay may determine its potential uses in bulk, or it may be advisable to remove the impurity, either to improve the grade and quality of the clay or to provide a useful by-product. The application of both qualitative and quantitative thermal data, in the analysis and control of laboratory work in this field, is demonstrated by its use in the assessment of materials such as evaporite-rich clays, siliceous clays, and high-alumina clays.

Due to the high proportion of impulse purchases and the short time devoted to purchase decisions, packaging and other extrinsic attributes are becoming increasingly important in demonstrating the health benefits of a functional food item to consumers as plausibly as possible. Our research aims at identifying the role of extrinsic features (claims related to ingredients and health claims, organic or domestic origin, as well as the shape and color of packaging), gathered in the course of in-depth literature analysis, in the case of a functional smoothie. Our online consumer questionnaire was completed by 633 respondents, and the answers were assessed by choice based conjoint analysis. Our results show that each examined attribute plays a role in the assessment of health effects. The color blue has the biggest impact on making the consumer believe in the health benefits of the product. This is followed by the indication of organic origin, then the statement emphasizing the natural quality of the ingredients. The assessment of the specific extrinsic attributes is affected by consumers’ general health interest level, their involvement with food items, and their various demographic features.
