"This thesis is using a non-parametric methodology, an extention of Linear Programming of what so called Data Envelopment Analysis (DEA). We estimate efficiency scores for DKI Jakarta public secondary high-shcool, using data mainly for year 2004 and 2005. The input measures are constructed from the new entrance student's minimum national examination score (NEM), annual school revenue per student from the government subsidies as well as from the public, while the outputs measures are based on the national examination (UAN) score of the respective students, UAN pass rate, and the rate of students entering public universities. Using DEA we are able to separate schools that might qualify, as "performing well" from those were some improvement might be possible in terms of efficiency, and to identify the benchmarks as well as to provide the input target needed by the inefficient school in order to reallocate their resource more efficiently. Furthermore we advance the use of non-parametric rank-sum test to prove whether the population that grouped by the intensity of school revenue from public per students, would positively correlated with the level of school performance in efficient term."

"This research is intended to describe the efficiency level of rice agriculture in Central Java. Agribusiness approaches enable to explain the agriculture sector more comprehensively, focusing on agriculture with its backward and forward subsystems. This research employs DEA (Data Envelopment Analysis) to compute efficiency level, and covers fourteen districts with land productivity above the province average level. This research finds that only four districts perform efficiency level 100 percent relative to other districts. The solution for this inefficiency problem can be achieved by employing managerial simulation generated by DEA."

"One of the spirits of decentralization in carrying local governance aout currently, is signed by regional willing to conduct regional expansion. It is realized by the establishment of new autonomous region. There are some considerations on the establishment of new autonomous region, such as to get the service closer to people, efficiency of national governance implementation, effectivity of resources use and capability, strangthening local democracy and effort to maintain locality uniqueness. Nevertheless, whatever is the reason of the establishment of new autonomous region, refers to the last aims achievement, which is to make governance more efficient on the use of provided resources, the governance more efficient on the use of provided resources, the governance is more effective in realizing people's welfare and more democratic where all the rights and responsible are conducted fairly."
