Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 134-138 One of the growth indicators that can be used to assess a child's developmental growth is through skeletal maturation. Skeletal maturity can be evaluated by using anatomical changes of the cervical vertebral bones observed on the lateral cephalometric radiographs. The purpose of this study was to determine the stage of cervical vertebrae maturation of Hb E B thalassemia patients by comparing the shape changes of the second to fourth cervical vertebrae bodies with a control group. The design of this study was a cross sectional. The subjects were children with Hb E B thalassemia aged 9-14 years. The results showed that the retarded maturation of the cervical vertebrae in Hb E B thalassemia was not found in subjects of pre-puberty age (9-11 years old), but in those of puberty age (12-14 years old).;One of the growth indicators that can be used to assess a child's developmental growth is through skeletal maturation.

Tujuan dari penelitian ini adalah untuk meneliti pengaruh 0,25 % Molibdenum (Mo) yang dikandung dalam besi tuang nodular terhadap sifat mekanis Austempered Ductile Iron (ADI). Variasi temperatur dan waktu tahan digunakan dalam proses perlakuan panas. Dengan 0,25 % Mo dalam besi tuang, ADI yang dibuat, menghasilkan suatu nilai tegangan tarik yang besar dan menurunkan elongasi bila kita bandingkan dengan as-cast (paduan dan non paduan besi tuang tanpa perlakuan panas). Nilai energi impak terbesar didapat pada temperatur austenisasi 9000 C dan austempering 3750 C dengan waktu tahan selama 60 menit. Struktur berubah menjadi ausferrit.

The aim of this research is to investigate the effects of 0.25 % Mo (Molybdenum) which is contained in the ductile cast iron on mechanical properties of Austempered Ductile Iron (ADI). The various temperatures and the holding times are used in the heat treatment processes. Using a given 0.25 % Mo in the ductile iron, ADI's alloyed developes a higher ultimate tensile stress value and decreases the elongation if we compare with the as cast (non alloy ductile iron). The higher impact energy value obtained at 9000 C austenization and 375o C austempering temperatures during 60 minutes holding times. The structure changes into ausferrit.

This paper describes the case study of Semanggi intersection in Jakarta, a dynamic model of emission reduction in the land transportation sector. The urban transportation system is a complex system with multiple variables, feedback loops, and is influenced by social, economic and environmental factors. The proposed model consists of two submodels: Vehicle Fleet and Emission Calculation. The model runs in Powersim Studio software using data from the Indonesia Japan Economic Partnership Agreement, and the Traffic Management Centre of the Indonesian National Police. The test was conducted by developing two scenarios: Business As Usual and Intention. The estimated results to be obtained using the first scenario in 2021 should be 1,113,398 units, while the second scenario is estimated to produce 850,733 units. We hypothesize that the Intentional Approach will have a more significant impact than the Technical Approach, which requires more investment. The Intentional Approach is designed to improve the intention of private car users to switch to public transportation. The Technical Approach to the emission measurement of every vehicle in a certain area is the data of vehicle emission which are usually taken to determine the current condition. This research will no doubt have a positive impact on emission reduction in Jakarta.
