Abstract

Indonesias forest is one of the centers of biodiversity in the world, where Indonesia is the third of seven countries called mega diversity country. The high rate of deforestation is causing the failure to achieve forest sustainability. It is reinforced by the presence of illegal logging. Illegal logging is a major cause of deforestation in Indonesia, which reached a level speed of 1.6 - 2.0 million hectares per year. That is why the Ministry of Forestry Indonesia has put the eradication of illegal activity including illegal timber trade. This study was conducted to identify why illegal logging is difficult to stop, and what are the impacts caused by illegal logging on the physical and biotic environment.This study is a literature study and case studies, in order to identify why it is hard to stop illegal logging and also the impacts caused by illegal logging on the physical environment and biotic environment.It is showed that illegal logging is symptoms that arise due to the highly complex issues involving multiple parties from different layers. Illegal logging has become a national issue which the commitment of governments at the national level must be real. However, because this problem occurs at the local level, then the commitment should also be clear areas in which Local Government must have a real responsibility. In general, the problems that led to illegal logging can be grouped into: supply-demand imbalance; government policies that are less precise; multi-dimensional crisis; excesses of decentralization (regional autonomy), and moral forces. A loss due to illegal logging has a broad dimension not only to economic problems, but also to social, cultural, political and environmental. In connection with the problems above , there are some required actions and commitments that must be implemented in an integrated and simultaneously involving the various parties involved stakeholders.

Abstract

Presence of water on earth not all of them can be used by living beings, especially humans. Watershed Loano Hulu is one of the watershed located in Central Java province. Loano DAS has a function for the area underneath. For the study of water balance is necessary to know the potential of water in the watershed, thereby criticality index can be determined so that the water in the watershed can be determined for watershed management measures are to be maintained. The purpose of this study is to determine the Water Holding Capacity (WHC) at the sites and determine the Water Balance. The research was conducted in the Upper Basin Loano Purworejo in Central Java Province. The research activities carried out in June 2009. The method used in the implementation of this study using the Thornthwaite-Mather. Data obtained on the basis of data WHC soil texture and extensive vegetation cover or land use, but it also needs climate data. Based on the results of the calculation results obtained WHC Loano watershed upstream of 245 mm. The size of the WHC reflects both the poor condition of a watershed. If the WHC of the watershed condition is very good, because it can save large amounts of water. Conversely the small WHC watershed condition is not good then it means the ability to store water is a small watershed. WHC value of  245 mm for the watershed Loano Hulu reflect the ability of the watershed to store water is high enough, so that the watershed is included in the DAS good condition. In meteorological amount of rainfall that occurred in the Upper Basin Loano big enough in January to reach 400 mm, the amount of rain up in June is still able to compensate for potential evapotranspiration occurs. Water deficit occurred during the five months from June to October occurred. Evapotranspiration that occurs less than the rainfall that occurred, so the watershed is a meteorologist had a surplus of water. Key words: soil, landuse, water holding capacity, water balance

Abstract

Packed ice snacks are often sold in Elementary School environment at city center area, central city, and suburbs area of Malang. The packed ice snacks were made traditionally by the people using water and the water wells. Schools used as a place to sell by the sidewalk vendors, the school also provided the best-selling to selling ice because the elementary school children with their high activity may cause them thirst, and it will allow them to buy packed ice snacks sold in around the school. Generally, the elementary school students do not know the types of snacks consumed, they just know that by drinking ice can relieve their thirst, other than that they didn’t think about the dangers posed by drinking unhygienic ice. By drinking unhygienic ice will cause sickness on students that can affect their learning activities in school. One of types of beverages sold in elementary school is packed ice. Packed ice is likely to be contaminated by pathogenic bacteria which enabling certain standards to ensure the cleanliness. Water and food contaminated by pathogenic bacteria digestive tract is very dangerous to drink, particularly the water that comes from the well which it less qualified microbiology quality. Keywords: quality, microbiology, snack ice pack, MPN value, Coliform bacteria, Coliform fecal bacteria, E. coli bacteria.

Abstract

         Mangroves are very important in coastal resource management. The most important function of mangroves for coastal areas is the link between land and sea. Plants, animals, other objects, and plant nutrients are transferred to the mainland or to the sea through mangrove. Mangroves act as a filter to reduce the adverse effects of major environmental change, and as a food source for marine (coastal) and terrestrial biota. The relationship between the region means that biodiversity around mangroves should also be considered, so that the total biodiversity of ecosystems is higher. Beside that economic potential of mangroves in Sidangoli can earn from three main sources namely forest, estuarine and coastal fisheries (shallow water), as well as natural attractions. Because of population pressure, especially coastal areas Sidangoli, resulting in a change in land use and utilization of natural resources in excess, if not protected by mangrove forests quickly become thinner and broken in the coastal Sidangoli. The need to balance must be achieved between meeting the needs now for economic development at a party, and conservation of environmental support systems on the other. Growing awareness of the protection function, the productive and socio-economic impacts of mangrove ecosystems in the tropics, and due to the decreasing availability of natural resources, encourage the lifting of the problem needs conservation and sustainability of the integrated management of resources-such valuable resources. Given the potential for multi-use natural resources, it is imperative that the management of mangrove forests based on terrestrial and aquatic ecosystems, in relation to integrated coastal zone management plan.

Abstract

Protection and development of local-breed breed is very important because it can utilize low-quality feed and are more resistant to environmental stress and disease. It is very important also for the development and utilization of local breeds because they are very well adapted to their environment, with a very limited nature and management are very low. The method used was literature study, which is to identify how the environmental effects toward the phenotypic Plasticity livestock.The results of research showed that the phenotypic and genotypic expression is caused by environmental factors such as pathogen infection or a biotic factors (light, temperature, oxygen, drought, nutrients) as well as the use of biotechnology through genetic engineering (gene recombination), gene expression conducted in two stages,transcription and translation. Protein synthesis mechanisms controlling gene regulated by the regulator (regulator gene), gene operator (operator gene), and gene structure (structural gene). On one way to regulate the effectiveness of the enzyme by  genetic control, development of farm businesses in areas that have problems due to a less than optimal environment, it can develop local cattle. Keywords: environment, phenotypic plasticity, livestock.
