Judul: Aplikasi Logika Fuzzy pada Sistem Kendali Suhu untuk Transportasi Ikan dan Udang Hidup Sistem Kering
Abstrak: Udang merupakan salah satu komoditi non migas yang menjadi andalan negara. Potensi Indonesia akan udang tiap tahun mengalami peningkatan, sampai tahun 1997 produksi udang tambak adalah 109 270 ton (Widodo, et al., 1998). Udang mempunyai nilai jual yang sangat tinggi, terlebih apabila masih dalam keadaan hidup. Disamping itu permintaan akan ikan air tawar dalam keadaan hidup juga meningkat. Saat ini cara transportasi yang dilakukan dalam perdagangannya antara lain dengan menggunakan air tawar dan air laut/tambak. Cara ini dianggap kurang efisien karena diperlukan banyak air tawar dan air laut kemudian juga harus tetap menjaga suhunya. Cara yang lain adalah dengan memingsankan ikan maupun udang terlebih. dahulu dan kemudian menjaga agar suhu saat transportasi dapat stabil pada suhu pingsannya.

Judul: Pengaturan Suhu dengan Logika Fuzzy untuk Transportasi Udang Windu (Penaeus Monodon Fab.) Hidup Sistem Kering
Abstrak: Distribusi komoditas perikanan dalam keadaan hidup memerlukan penanganan dan sistem transportasi yang baik. Penggunaan serbuk gergaji sebagai media hidup merupakan salah satu metode transportasi sistem kering yang dapat diterapkan pad a udang windu tambak (Penaeus monodon Fab.). Sistem transportasi ini bertujuan mempertahankan suhu pengangkutan sehingga udang tetap pada kondisi imatil dengan tingkat mortalitas serendah mungkin. Kondisi ini dapat dicapai dengan mengontrol suhu pengangkutan terusmenerus. Pengaturan suhu yang dilakukan adalah secara semi otomatis yang lebih bersifat on-off dan pengaturan suhu secara otomatis dengan logika fuzzy.

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.
