Judul: Metode double chain ladder untuk memprediksi besarnya cadangan klaim IBNR dan RBNS
Abstrak: Perusahaan asuransi wajib menyediakan cadangan klaim untuk memenuhi kewajiban membayar klaim di masa yang akan datang. Salah satu metode untuk memprediksi besarnya cadangan klaim adalah metode Chain Ladder. Metode Double Chain Ladder adalah metode Chain Ladder yang digunakan dua kali. Metode Double Chain Ladder dalam aplikasinya dapat memprediksi besarnya cadangan klaim IBNR (Incured But Not Reported) dan RBNS (Reported But Not Settled) secara terpisah. Karya ilmiah ini menjelaskan cara menduga besarnya cadangan klaim menggunakan metode Double Chain Ladder dan membandingkan hasilnya dengan menggunakan metode Chain Ladder.

Judul: Proyeksi cadangan klaim dengan metode Munich chain-ladder
Abstrak: Insurance companies are required to manage the appropriate claim reserves to cover the expenses of the claims that will occur in the future. One of the claim reserves estimation method that frequently used is the chain-ladder method. Because of the simplicity of this method, many insurance companies use the method to estimate the claim reserves in the future. However, the chain-ladder method is not able to reduce the gap between the projection of IBNR (Incurred but Not Reported) paid losses and incurred losses. The Munich chain-ladder is the development of the chain-ladder method introduced by Gerhard Quarg and Thomas Mack. The Munich chain-ladder method can be applied to reduce the gap between the projection of IBNR paid losses and incurred losses. This paper describes how to estimate the claim reserves using the Munich chain-ladder method and to compare the results with using the chain-ladder method. In addition, we provide examples of data, where the Munich chain-ladder method does not produce a good projection.

Judul: Studi Kasus Patologi Infeksi Protozoa Tetrahymena spp pada Ikan Hias Guppy (Poecilia reticulata )
Abstrak: The study was aimed to explore the protozoan Tetrahymena spp infection in Guppy (Poecilia reticulata) fish, with intended to the morphology of parasites in tissue sections and the resulting tissue lesions. Sample of diseased Guppy fishes were used in the study. Observation of clinical symptoms of the Guppy were revealed lethargic, vertical swimming and impaired equilibrium. The fish organs were observed macroscopically and microscopically. The result of macroscopic observation showed that there were excessive haemorrhage and ulceration at skin particularly in the dorsal and lateral abdomen. Protozoan parasite in the skin, muscles and gill tissues were identified by histopathological examination using hematoxylin-eosin staining and positive responses to periodic acid Schiff staining. Study of protozoan morphology revealed a spherical shape pyriform with a narrow anterior end, have dimension in average 50.5 x 32.4 μm. The parasites cause skin erosion, and hemorrhage, muscular degeneration and necrosis along with gills edema. Severe fatty degeneration was presented in liver while there was edema and congestion in the intestinal mucosa. As these fishes were been cultured in the aquarium such disease is thought to be caused by the deterioration of water quality, feed contamination or a poor handling.
