Judul: Manajemen Penangkaran dan Aktivitas Harian Kalong kapauk (Pteropus vampyrus Linnaeus 1758) di Taman Margasatwa Ragunan
Abstrak: Utilization of large flaying fox from nature and the damage of natural habitats of large flaying fox makes population diminish. Therefore large flaying fox need to be captivein order to keep large flaying fox populations in natural habitats remain sustainable. The purpose of this research is to study the technical aspects of captive management and identified daily activity of large flaying fox in the enclosure. The method used for captive management is field observation, interviews, and literature, while for daily activities using scan animal sampling method against two groups of large flaying fox by sex (male and female). There are 13large flaying fox in TMR (7 males and 6 females). Bat enclosures have a size of 12 m x 4 m x 4 m. Large flaying foxin TMR are given feed papaya, banana, and guava. Results of the implementation of animal welfare outcomes calculation of 2.51 and included in good categories. Daily activity of large flaying fox were identified are, grooming itself, perch, resting/sleeping, eating, communicate, and moving. Based on the results of chi-squared test, daily activities of large flaying fox male and female are generally the same.

Abstrak: Ragunan Zoo is one of the conservation organizations that carried animals management based on the principles of ethics and animal welfare. Beside that, it also has a function as recreation place.The purpose of this research is to identify and analyze management of common palm civet welfare and its of prosperity level in Ragunan Zoo, measuring interests of the visitors Zoo about the common palm civet, and also make recommendations for better management in common palm civet welfare.The results showed that management of common palm civet in Ragunan Zoo consists of three main activities, which are housing, feeding, and health. The welfare of common palm civet in Ragunan Zoo also classified as good. This animal is one of the favorite animals viewed by visitors. The recommendation that Ragunan’s management to put a lot of their attention in cages of common palm civet, because many of the cages are need to be repaired

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
