Acid rain contribution from pesticide distribution to rice farmers in Pati Regency

-
Productivity rate of rice fields in Regency has been in a surplus condition annually. The fields have produced 7 to 8 tons per hectare, making the total annual rate of 600 tons. The regency, therefore, is considered to be capable of fulfilling its own need for rice and to contribute significantly to the rice needs in Central Java Province. Agriculture coexists with the presence of pesticides. While helping the farmers to combat the plant diseases, pesticides have still been greatly necessary by the local farmers. Distribution by means of transportation devices plays an important role for the dissemination of the pesticides from the producers to their end users. Problem arises due to emission produced during the transportation activities. Transportation emits SO2 as the major contributor to acid rain. To make worse, application in practice by the farmers also emit the similar substance. Annual use of pesticides in Pati Regency has reached 605 tons with SO2 emission of 13,697 kg. It is recommended that distribution management and selection of pesticides are performed by applying an integrated pest control in order to reduce the pesticide emission.

Healthcare Waste in the United States Healthcare System

-
How America will pay for healthcare is a subject on the mind of virtually every American today. As Congress determines who will pick up the tab for this important and growing expense, it is worthwhile to take a close look at the cost of healthcare itself. Are there areas where expenses can be cut without undermining the quality of care provided? How prevalent are misuse, overuse, and fraud? This paper tackles the tangled issue of healthcare waste and arrives at some interesting, and perhaps even surprising, conclusions: America’s healthcare system is, indeed, hemorrhaging billions of dollars, and the opportunities to slow the fiscal bleeding are substantial. To organize the evidence supporting claims for the magnitude of waste in the healthcare system,we first suggest a set of categories of waste. For each category, there is a simple definition, a brief description of the examples, and references that allow us to make a reasonable assessment of total annual waste for each category. Ca

A study of drinking water quality of PDAM

-
One of problems faced by community dealing with water services provided by the State-owned Water Company (PDAM) is inadequacy of the services in fulfilling household needs. Customers often complain because this limited volume of water they can use for daily activities, such the research found in a service quality analysis of drinking water provided by PDAM. The study on service quality may have its cornerstones on three main aspects: the quality, quantity, and continuity.  In case of drinking water quality at the observed location, one should relate it to the quality threshold under the Letter of Decree of the Minister of Health Affairs of the Republic of Indonesia, Kepmenkes RI, No.907/MENKES/SK/VII 2002, which has been applicable since July 28, 2002. In addition, there is also another technique of analysis to measure the water quality level by examining water debit, water pressure, and flow continuity. However, to deal with PDAM’s vision and mission, service quality analysis is lik

International Forestry LawReducing Emissions from Deforestation and Forest Degradation (REDD) and decentralized forest management

-
Authors: Irawan, S.; Tacconi, L The implementation of a mechanism for Reducing Emissions from Deforestation and Forest Degradation (REDD - plus) will be affected by governance conditions within host countries. The top eight countries, which are responsible for 70 percent of the world's total annual deforestation, have implemented certain forms of decentralization in public administration and forest management. This paper analyzes implications of decentralized forest management for the implementation of REDD. Three possible options for the involvement of local governments in the implementation of REDD are: 1) the central government decides on a national reference level and devolves the implementation to local governments; 2) the central government decides on a national reference level and seeks expressions of interest from local governments to implement REDD in their administrative areas; and 3) the central and local governments decide on a national reference level jointly and loc
