Dalam beberapa tahun terakhir frekuensi penggunaan sistem satelit navigasi global (Global Navigation Satellite Systems (GNSS)) telah semakin gencar. Semakin banyak negara yang menerapkan teknik pengukuran berikut pengembangannya untuk aplikasi survei dan navigasi. Bidang transportasi kereta api juga tidak luput dari sentuhan GNSS. Penelitian ini menggunakan metode analisis geometri jalur kereta api berdasarkan pengukuran satelit bergerak dengan tujuan mengetahui pengaruh implementasi geometri jalur kereta api pensurvei satelit. Proses pengamatan yang diuraiakan di dalam penelitian ini terbagi ke dalam dua tahap. Tahap pertama adalah survei bergerak (mobile surveying) GNSS dan data yang diperoleh dari analisis. Tahap kedua berupa analisis geometri jalur/trek dengan menggunakan koordinat-koordinat datar dari survei. Visualisasi rute yang diukur, analisis pemisahan dan kualitas dari elemen-elemen geometris yang seragam (yakni, jalur lurus, jalur melengkung), identifikasi poligon trek (arah utama dan sudut simpangan) dibahas dan diilustrasikan dengan disertai contoh penghitungan.

Bureaucratic Issues in Indonesia

-
Reform experienced by Indonesia in 1998 has led to major change nationwide. The change took place as far as governmental administration process. Bureaucracy as part of the government’s job description, was also affected by the reform. The movement towards change required bureaucracy to be more neutral, transparent, responsive, and accountable, politically. Such demand has pushed the bureaucrats to create a new frame and characteristic building in answering their responsibility to fulfill the needs of people as their constituents. In practice, Indonesian bureaucracy truly needed more experience to anticipate this massive change. For example, there were still many handicaps in providing public services. This situation opposed to the previously idealized dream, a government as a good servant for the citizens. Many elements of the current government administration were reluctant to fulfill the people needs voluntarily. Bureaucracy, which initially aimed to simplify administration process, ...

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...

Contemporary Development Administration

-
Author: U. C. Mandal Title: Development and public administration The problems of public administration in developing countries are so vastly different from those of the developed world that a new discipline, development administration, has emerged since the 1960s to study them. Although a large number of books and articles have been written on the subject, questions still persist as to whether such a discipline exists or is necessary. Nevertheless, development has become a major focust of administrative activity in the countries of the Third World. The industrialized societes have recognised the need for these countries to gear their administrative machinery to new developmental tasks and responsibilities. The major political phenomena in the latter half of the twentieth century constitute an intricate and complex subject, but they are susceptible, at the risk of oversimplification, to relatively brief summary and analysis. The first and most obvious condition has been the tremen...
