Judul: Kajian Efisiensi Sistem Pengolahan Air Limbah PT. UNITEX Serta Dampaknya Terhadap Perairan
Abstrak: Penelitian ini bertujuan untuk mengkaji : (a) tingkat efisiensi masingmasing unit pengolahan air limbah PT. UNITEX (b) kualitas air limbah olahannya dikaitkan dengan baku mutu air limbah olahan industri tekstil yang ditetapkan Pemerintah RI (c) volume dan cara penanganan by product (berupa lumpur kimia dan biologi) dari hasil pengolahan air limbah PT. UNITEX (d) besarnya kontribusi bahan pencemar (berasal dari air limbah terolah PT. UNITEX) terhadap badan air penerima. Penelitian ini dilakukan di IPAL PT. UNITEX Jln. Raya Tajur No. 1 Bogor, pada April – Juli 2009. Pengambilan air contoh dilakukan di tiga titik IPAL PT. UNITEX yaitu pada inlet, aerasi dan outlet sebanyak enam kali pengamatan, serta tiga titik Sungai Cibudig yaitu 20 m sebelum saluran akhir air limbah olahan PT. UNITEX , 20 m dan 200 m setelah saluran akhir air limbah olahan PT. UNITEX Pengukuran kualitas air berupa parameter fisika (suhu dan TSS), parameter kimia (pH, DO, BOD dan COD) dan parameter biologi (Jenis mikroorganisme, F/M Ratio da SVI). Efisiensi IPAL PT. UNITEX secara keseluruhan (inlet-outlet) cukup tinggi (69,11% untuk BOD, 78,97% untuk COD, dan 83,73% untuk TSS), sehingga secara umum konsentrasi bahan pencemar (28,97 mg/l untuk BOD, 142,71 untuk COD, 40 untuk TSS, suhu 33,60C, pH 7 dan DO 3,6 mg/l) dari air limbah olahan yang dibuang ke Sungai Cibudig telah memenuhi baku mutu limbah cair industri tekstil yang ditetapkan pemerintah (SK. Gub. Jawa Barat No. 6 Tahun 1999 tentang Baku Mutu Limbah Cair Industri di Jawa Barat).

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.
