"This paper is set up to describe tools, techniques, and its application on granite open pit mining in Mt. Peniraman, Kalimantan, Indonesia. The aim is to achive optimum design of rock slope stability. The design is based on the theory of stereographic projections using software program data interpretation package (DIPS). As a result of calculation and observation of rock mechanics condition in the field, geological structure are of great significance."

"Interferometric SAR (IFSAR) offers a solution for a country like Indonesia to map areas that are covered by cloud all year long. In using IFSAR data for producing topographic maps, our main requirement is to set the procedures that resemble photogrametric process as close as possible due to the operators, background and the already available sofware and haedware...."

"Penelitian eksperimental ini menguji efektifitas modul membaca peta terhadap keberhasilan anak usia 5 tahun dalam menemukan lokasi yang tertera di dalam peta. Pada modul membaca peta, dua konsep yang ditekankan adalah konsep birdeye view dengan tujuan anak mampu menerjemahkan bentuk bangunan ataupun patokan (landmark) jika digambarkan pada peta dan konsep mengartikan simbol pada peta.Penelitian ini melibatkan 30 anak usia 5 tahun. Dibandingkan dengan anak yang tidak mendapatkan pengajaran modul membaca peta, anak yang mendapatkan pengajaran modul membutuhkan waktu yang lebih cepat dalam mengerjakan tugas, selain itu mereka juga lebih tepat dalam menemukan lokasi yang tertera di peta Saran untuk penelitian lanjutan mengenai membaca peta dan mencari lokasi pada anak mencakup mengefektifkan pengajaran membaca peta dan pengamatan perilaku yang muncul ketika anak membaca peta.

The research examined the effectiveness of map reading skill module in finding a place on the map for 5 year-old children. Two concepts were emphasized during lesson: firstly, concept of "bird eye view" which allowing children to be able to understand the form of the building and to recognize directly the landmark on map and secondly, the concept of understanding the symbols.This research involved thirty children as subjects, divided into two groups, the experimental group (those with the lesson of map reading) and the control group (who received no mapreading lesson). The result of the research showed that the control group has difficulties to find a place on map and took longer time than the experimental group. Further research should take consideration in optimalizing the method of teaching the map-reading lesson and applying more behaviors to be observed as indicators of wayfinding behaviors."

"Evaluasi persamaan matematik perpotongan dua garis untuk rekonstruksi koordinat dua citra proyeksi sinar-X telah dilakukan. Tujuan evaluasi adalah untuk menentukan angka kesalahan dalam proses rekonstruksi dan karakteristik praktis-nya ketika persamaan rekonstruksi tersebut digunakan oleh perangkat rekonstruksi koordinat sistem brakitherapi. Faktor kesalahan manusia diantisipasi akan masuk melalui variabel data yang digunakan dalam persamaan tersebut, karena data tersebut berasal dari dua citra proyeksi sinar-X semi-orthogonal yang ditentukan secara manual menggunakan perangkat lunak penampil citra. Evaluasi dilakukan dengan cara membandingkan hasil titik rekonstruksi dengan titik yang telah diketahui koordinatnya, serta menghitung deviasi hasil rekonstruksi terhadap beberapa titik lain yang diambil dengan orientasi proyeksi yang berbeda. Hasil pengujian menunjukkan bahwa proses rekonstruksi koordinat menggunakan teknik titik potong dua garis lurus ini mempunyai kesalahan 0,1 cm menggunakan resolusi citra proyeksi 80 pixel per cm. Proses rekonstruksi berpotensi gagal jika resolusi citra yang digunakan dibawah angka tersebut.

An evaluation of two lines crossing mathematical equations for coordinate reconstruction of two X-ray projection images has been done. The purpose of the evaluation is to define its error value and its practical characteristics when the equations are used during reconstruction process to determine the coordinate on a brachytherapy system. Human error will be involved through the data variable used by the equations as these data are obtained from two images of semi orthogonal X-ray projections detremined manually using an image viewer software. The evaluation is implemented by comparing the point as the result of the reconstruction with those that have been known their coordinate values and computing their reconstruction deviation toward some fix points that were taken their images from different projection orientation. The test results showed that the reconstruction coordinat process using a point of two straight lines intersection method has an error of 0.1 cm using a projection image resolution of 80 pixels per cm. The reconstruction process is potentially fail if the resolution image used below the number."
