Judul: Pengaruh Perubahan Penutupan/Penggunaan Lahan terhadap Karakteristik Hidrologi Sub DAS Ciliwung Hulu
Abstrak: Watershed is an ecosystem consisting of upstream, middle and downstream. Upstream watershed ecosystem is play an important role, because its function to regulate hydrologic characteristics of the watershed. Ciliwung watershed is one of the superpriority watershed that must be taken high priority effort to rehabilitation. According to Suripin (2002), hydrological components affected by development activities in the watershed includes surface flow coefficient, coefficient of discharge regim river, the ratio between maximumminimum river discharge, mud content or sedimentary deposits in the river, the rate of frequency and period of floods, and also the state of groundwater. The aim of the research is to analyze land use/cover, changes of land use/cover in upstream ciliwung watershed and to analyze its influence on watershed hydrology (flood and maximum-minimum river discharge). In this research landsat image of 1990, 2001 and 2010 was used to analyze the land use/cover changes. After that the condition of land use changes and characteristics of watershed hydrology were compared and evaluated. Based on image interpretation of land cover in 1990 and 2001, the area dominated respectively by dense jungle, mixed farms and tea plantation. While land use in 2010 is dominated respectively by dense jungle, tea plantation and settlement. Patterns of land use/cover change at period 1990-2001 indicates substantially conversion of agriculture land such as the rice field, dryland farming and mixed farms into settlements. Area that converted respectively are 238.8 ha, 238,5 ha and 127,8 ha. Bush land is transformed into agriculture land as well, which are tea plantation (180,1 ha), mixed farms (140,7 ha) and other agricultural cultivation. Mixed farms is the most intensively converted land into dryland farming (411,3 ha). In the period 2001-2010, pattern of landuse/cover changes that occured is not too different but in a much larger scale. Large conversion of agriculture land occurred toward settlement (rice field 231,3 ha, mixed farms 176,2ha and dryland farming 128,9 ha). Mixed farms was converted into dryland v farming are 329,5 ha and rice field 212,8 ha. Amount of bush land converted to tea plantation, rice field and dryland farming were respectivally 107,1 ha, 144,9 ha and 108,4 ha. A decline in the quality of the upstream ciliwung watershed hydrology can be seen from characteristic of flood frequency, the quality of a flood, maximum-minimum river discharge and the ratio between maximumminimum river discharge. Increase of settlement and dryland farming area in the upstream ciliwung watershed contribute to declining of upstream ciliwung sub watershed hydrology characteristics.

Judul: Pengaruh perubahan penggunaan lahan terhadap karakteristik hidrologi DAS Citarum Hulu
Abstrak: Land use change in a certain area will affect hydrologic characteristic there, so that it can be used as a reference whether the area is critical. This research objective is to study the effect of land use change to hydrologic characteristic of Upstream Citarum Watershed. There are 5 sites observed in Upstream Citarum watershed: Cikapundung, Citarik, Cirasea, Cisangkuy, and Ciwidey. This research was carred out by analyzing data of rainfall, discharge, and runoff, and by observing land use map. The result of analysis was then linked and matched to the data of land use descriptively. The result of this research showed that Cisangkuy sub-watershed was the worst due to its hydrologic characteristic. It can be seen from its increase in discharge and relatively high runoff coefficient in 2008, compared to ones of 2003. This condition was caused by land use changes happened there, which were decreasing primary land dry forests area, and increasing settlement area and wet rice field.

Judul: Anatomi otot daerah manus monyet ekor panjang (Macaca fascicularis)
Abstrak: Macaca fascicularis dinamakan monyet ekor panjang karena ukuran ekornya panjang, kira-kira sama dengan panjang bagian kepala dan badannya (Napier dan Napier, 1967), selain itu M. fascicularis disebut juga "crab-eating monkey" karena kepiting merupakan salah satu jenis pakan yang paling disukai oleh monyet ini. Satwa primata merupakan hewan yang cocok sebagai hewan model untuk manusia karena kedekatan hubungan filogenetis serta kemiripan anatomis, fisiologis, biokimiawi dan respon farmakologisnya dengan manusia dibandingkan hewan percobaan lainnya (Sajuthi, 1984). Penelitian ini bertujuan untuk mengetahui susunan otot daerah manus beserta origo dan insersionya guna melengkapi data dasar anatomi otot pada M. fascicularis. Penelitian ini menggunakan enam kaki depan kiri dan tiga kaki depan kanan M. fascicularis yang telah diawetkan dalam formalin 10%. Pengamatan yang dilakukan meliputi morfologi dan susunan masing-masing kelompok otot lengkap dengan origo dan însersionya, kemudian membandingkan dengan literatur mengenai morfologi dan susunan otot daerah manus tangan manusia. Hasil pengamatan morfologi luar sebeluın dilakukan penguakan kulit terlihat bagian dorsal kaki depan monyet ekor panjang ditutupi oleh rambut yang berwarna coklat kehitam-hitaman. Sedangkan bagian distal tidak ditumbuhi rambut, berkulit tebal, mempunyai bungkul-bungkul yang terbagi dengan jelas dan mempunyai gambaran sidik telapak dan jari. Otot-otot mamus M. fascicularis terdiri atas tiga kelompok otot yaitu kelompok thenar, hypothenar dan palmar. Kelompok otot thenar terdiri atas empat otot yaitu m. abductor pollicis brevis, m. opponens pollicis, m. flexor pollicis brevis dan m. adductor pollicis. Keempat otot pada kelompok thenar ini berbeda origonya dengan manusia. Musculus abductor pollicis brevis pada M. fascicularis berorigo di os navicularis dan os sesamoideum. Pada manusia kedua tulang ini tidak ada. Pada manusia otot ini berorigo pada retinaculum flexorum, bungkul os scaphoideum, os trapezium dan berkas tendo dari m. abductor pollicis longus. Musculus opponens pollicis pada M. fascicularis berorigo di ligamentum carpi transversum dan tendo dari m. abductor pollicis longus. Pada manusia otot ini berorigo pada retinaculum flexorum dan bungkul os trapezium, Musculus flexor pollicis brevis pada M. fascicularis dan manusia terbagi menjadi dua caput yaitu caput superficial dan caput profundal. Kedua caput pada M. fascicularis memiliki origo yang berbeda dengan manusia. Caput superficial pada M. fascicularis berorigo di ligamentum carpi transversum, sedangkan caput profundal berorigo di proksimal os metacarpal II sisi radial dan os trapezoideum sisi ulnar. Pada manusia, caput superficial berorigo pada retinaculum flexorum dan os trapezium, sedangkan caput profundal pada os trapezoideum dan os capitatum. Musculus adductor pollicis pada M. fascicularis dan manusia terbagi menjadi dua caput yaitu caput obliquus dan caput transversum. Kedua caput pada M. fascicularis memiliki origo yang berbeda dengan manusia. Pada M. fascicularis, caput obliquus berorigo pada os trapezoideum sedangkan caput transversum berorigo pada proksimal os metacarpal II dan III. Pada manusia, caput obliquus berorigo pada os capitatum dan proksimal os metacarpal II dan III, sedangkan caput transversum berorigo pada os metacarpal III dan beberapa serabutnya akan bersatu dengan m. adductor pollicis caput obliquus dan m. interossea palmaris 1…dst
