Judul: Aplikasi KlasifIkasi Wishart Untuk Pertambakan
Abstrak: Pengklasifikasian secara dijital akhir-akhir ini meningkat kebutuhannya untuk mengidentifikasi ataupun melihat kenampakan pada citra secara visual. Tujuan penelitian ini adalah membandingkan hasil citra yang dihasilkan oleh ketiga band AirSAR, yakni Band-C, Band-L dan Band-P. Klasifikasi Wishart Tak Terselia mengidentifikasi kenampakan endapan-endapan di dalam tambak secara detail dengan menunjukkan warna-warna yang lebih bervariasi dibandingkan dengan dekomposisi Freeman dan Cloude. Dengan pengaturan nomor pengulangan maksimum (maximum number of iteration) sebesar 10 dan persentase kelas piksel % of pixels Switching Class) sebesar 5% didapatkan hasil kenampakan endapan yang bervariasi pada tambak.

Judul: Pemanfaatan informasi tekstur citra sar (Synthetic aperture radar) untuk klasifikasi penutup lahan
Abstrak: Salah satu keunggulan sistem sensor SAR dibanding sistem sensor optik adalah kemampuannya untuk menembus lapisan awan. Citra SAR berbeda dengan citra sistem optik. Citra SAR selain hanya memiliki band tunggal juga pada datanya banyak mengandung noise (ingar) yang disebut speckles (noktah/bintik). Namun dalam citra SAR ada suatu informasi yang sifatnya spasial (keruangan) yang dapat digunakan sebagai input dalam proses klasifikasi, yaitu tekstur. Dalam penelitian ini dikaji pemanfaatan informasi tekstur citra SAR sebagai input dalam proses klasifikasi Penutup lahan. Berdasarkan nilai persentase ketelitian dan persentase banyaknya pixel yang tidak terkelaskan, penggunaan komponen utama hasil proses penyaringan (rataan, median dan Frost) relatif lebih baik dibanding input lainnya. Apabila dibandingkan dengan penggunaan data asli sebagai input, persentase ketelitiannya meningkat sebesar 10% sampai 30%. Dan apabila dibandingkan dengan input tekstur yang berasal dari cooccurrence matrix dan difference vector, persentase ketelitiannya meningkat sebesar 10% sampai 20%. Sedangkan jika dibandingkan dengan input hasil proses penyaringan, persentase ketelitiannya relatif tidak berbeda, namun penggunaan hasil penyaringan sebagai input dalam proses klasifikasi menyebabkan 0,83% sampai 32,66 % pixel tidak terkelaskan.

Judul: Studies on growth spurt and aging in higher primates
Abstrak: single measurement that best defines the health and nutritional status of children, just as it provides an indirect measurement of the quality of life of an entire population. The pattern of human growth reflects the biocultural evolution of our species. The human pattern of growth and development (ontogeny) appears to differ markedly from patterns of ontogeny in other primate species. Three studies are reported here which deal to the growth and development of human and chimpanzee (Pan troglodytes). These three studies allow us to contrast the phenomena of adolescence growth spurt and female elderly bone loss in chimpanzee and human as chimpanzee is the closest species to humans within extant nonhuman primates. In the first, a cross-sectional study of growth of the body size and somatotype of 363 Javanese girls and 299 Javanese boys aged 4 to 20 years from Magelang Regency, Indonesia was described. In the second, cross-sectional and longitudinal studies in the growth of chimpanzee second metacarpal bone linear dimensions from individuals aged 0 to 43.6 years were used for comparison. While in the third, cross-sectional and longitudinal studies in the growth of chimpanzee body size (body mass and anterior trunk length) and second metacarpal bone mineral content were derived. In measuring the second metacarpal dimensions and mineral content, a total of 568 radiographs of chimpanzee's proximodistal left hands were used. They were taken from 68 females and 49 males aged 0 to 43.62 years old. We applied an image analysis system, Scion Image Release Alpha 4.0.3.2 software for Windows to measure bone linear dimensions and bone mineral content. Humans present complex and sinuous growth curves for both body weight and height. A clear growth spurt could be demonstrated by cross-sectional analysis in our girl subjects at around aged 11.5 years and in our boy subjects at around aged 12.5 years. In longitudinal series, not in cross-sectional, several representative chimpanzees of both sexes showed a pre-adult growth spurt on the body sizes, bone dimensions and bone mineral content. They ranged at age 4.5 to 8.5 years. This underscore the fact that adolescent growth spurt in linear dimension was not a universal feature of anthropoid primate ontogeny. Bone loss is a well established characteristic of human female aging. Based on crosssectional analyses the sequential decline of bone mass in female chimpanzee may be said to be genuine. On the other hand, we found in adulthood through elderly, male chimpanzees show a longer plateau than female chimpanzee, that is, bone mineral content is maintained in male.
