Judul: Keragaman Jenis Tumbuhan Pakan Monyet Ekor Panjang (Macaca fascicularis) Berdasarkan Musim di Taman Wisata Alam Pangandaran
Abstrak: Keragaman jenis pakan monyet ekor panjang (Macaca fascicularis) di Taman Wisata Alam Pangandaran dapat diketahui melalui pendekatan studi pakan dengan metode analisis sisa pakan (feses). Tujuan penelitian ini adalah mempelajari komposisi jenis Ficus spp. sebagai sumber pakan monyet ekor panjang melalui identifikasi anatomi remahan yang terdapat dalam feses monyet ekor panjang pada musim hujan dan musim kemarau di TWA Pangandaran. Sampel feses merupakan hasil koleksi pada penelitian sebelumnya yang diambil pada bulan Februari 2014 dan Agustus 2014 di sekitar titik koordinat Ficus spp. yang dijumpai di TWA Pangandaran menggunakan GPS (Global Positioning System ). Sampel berupa remahan epidermis yang berasal dari feses monyet ekor panjang dibuat sediaan mikroskopis sayatan paradermal serta diidentifikasi berdasarkan pangkalan data penelitian sebelumnya. Jenis pakan dominan dan proporsinya berbeda pada musim hujan dan musim kemarau, karena setiap periode perkembangan tumbuhan di alam kelimpahannya tidak sama dan M. fascicularis menyukai buah Ficus spp. di musim kemarau. Jenis Ficus spp. yang ditemukan sebanyak 6 spesies. Hasil identifikasi anatomi tumbuhan dalam feses menemukan anatomi buah dan daun F. glomerata dan F. annulata terkandung di dalam botol sampel feses yang diambil pada musim hujan dan kemarau. Hal ini menunjukkan bahwa Ficus spp. tersebut dapat berbuah di sepanjang tahun serta keberadaannya penting bagi keberlangsungan hidup monyet ekor panjang di Taman Wisata Alam Pangandaran.

Judul: Studi Populasi dan Habitat Monyet Ekor Panjang (Macaca fascicularis) di Cagar Alam Pananjung Pangandaran Jawa Barat
Abstrak: Pananjung Pangandaran Nature Reserve is one of natural habitat for long-tailed macaque (Macaca fascicularis). This wildlife was listed as Least Concern status in IUCN (2013) and Appendix II in CITES. The result of the research, which was done in three observation tracks, showed a different density of long-tailed macaque. The greatest population density was found as Karang Pandan (22 ind/ha), while at second track (Tadah Angin) were 4 individuals/ha, and at the third track (Cikamal) there were 19 individuals/ha. The range of population at the first track as many as 22 ± 9 individuals, at the second track as many as 4 ± 2 individuals, and third track as many as 7 ± 4 individuals. The adult long-tailed macaque was found at most in this research. Sex ratio of long-tailed macaque at the first and third track was 1:4, and at the second track was 1:3. There were 48 plant species that were found in the area where the long-tailed macaque carried out their activity, and 22 of the species had potential for long-tailed macaque feed.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.
