Judul: Gambaran Histopatologi Hati Kalong di Gorontalo
Abstrak: Acerodon celebensis and Pteropus hypomelanus are the species of fruit bats that live in Gorontalo. They are potential as reservoir of infectious agents, such as Hendra virus, Nipah virus, and Menangle virus. The aims of this research were to study the histopathology of Gorontalo fruit bats liver and to examine the potency of Gorontalo fruit bats as host and reservoir of hepatitis-causing infectious agents. Hepatic tissues of the bats were stained with Hematoxylin and Eosin (HE) for histopathological examination, antibody polyclonal rabbit anti Coxiella burnetii FKH IPB for immunohistochemical examination, and Periodic Acid Schiff (PAS) to detect glycogen and parasite. Histopathological examination showed that most hepatic tissues had granulomatous inflammation. The hepatic tissues stained with PAS found the presence of glycogen and fungi that suspected as Blastomyces dermatitidis. Immunohistochemical staining for Coxiella burnetii showed negative results.

Judul: Studi kasus : gambaran histopatologi organ ginjal pada kalong di Gorontalo
Abstrak: Fruit bats were world wide distributed mammals including in Indonesia. This study used samples called Kalong Gorontalo (KG) of the kidney from three species of fruit bats (Acerodon celebensis, Dobsonia exoleta, and Pteropus hypomelanus) from Gorontalo, North Sulawesi. The aims of this study were to find out the histology overview and pathology condition from the kidney to know the pathogenesis of the disease that infected those fruit bats. Histological overview used Hematoxylin Eosin (HE) shows that the cell and tissue in all of the samples had some pathology condition such as : hydropic swelling, degeneration, necrosis, protein deposition in the tubulus lumen, and dilatation of tubulus lumen. Some of the samples that were KG 1, 4, 5, 6, 21, and 26 showed positive reaction with Periodic Acid Schiff (PAS), it means that there were glycogen deposition in kidney. In addition, sample KG 7 showed positive reaction PAS with budding cell inside that indicated a systemic mycosis.

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.
