Judul: Dampak Merger terhadap Profitabilitas, Skala Usaha dan Efisiensi Operasi PT Bank CIMB Niaga, Tbk
Abstrak: Merger occurs when two organizations that have similar size unite to build a single business unit. The purpose of this study was to (1) Assessing the level of profitability, business scale and efficiency opersai PT Bank CIMB Niaga Tbk before and after implementing the merger. (2) Assessing the profitability trend projections, business scale and operating efficiency of PT Bank CIMB Niaga Tbk. (3) Assessing differences in the level of profitability, business scale and operating efficiency levels of PT Bank CIMB Niaga Tbk before and after the merger. Based on the analysis of financial statements of Bank CIMB Niaga is known that after the implementation of the merger, the level of profitability that is represented by the return on assets (ROA) and return on equity (ROE), the level of business which is represented by market share, as well as the level of efficiency that is represented by BOPO showed improvement.While based on the results of paired samples t test comparing the financial performance of the 5 years before and 5 years after the merger is obtained results that based on the analysis of hypothesis testing known that the merger of Bank CIMB Niaga made no ill effects but not significant effect for the profitability, business scale and efficiency level

Judul: Analisis Efisiensi Perbankan Sebelum dan Setelah Dilakukan Merger
Abstrak: Pada tahun 2006, Bank Indonesia menerbitkan peraturan mengenai Kepemilikan Tunggal yang dikenal dengan nama Single Presence Policy (SPP). Tujuan utama dari Peraturan Bank Indonesia (PBI) ini adalah untuk mewujudkan struktur perbankan Indonesia yang sehat dan kuat, hal ini juga disebutkan pada Arsitektur Perbankan Indonesia (API) Pilar 1. Proses konsolidasi perbankan yang perlu dilakukan untuk mencapai tujuan tersebut. Salah satu proses konsolidasi yang dirasa perlu dilakukan adalah penataan kembali struktur kepemilikan Perbankan melalui penerapan kebijakan kepemilikan tunggal. Penelitian ini ingin mengukur dampak dari konsolidasi melalui merger yang dilakukan oleh bank-bank yang masuk kedalam ketegori SPP dari sisi efisiensi. Metode yang digunakan adalah Two-Stage Data Envelopment Analysis (DEA) dengan regresi Tobit. Kerangka waktu untuk penelitian ini adalah dua belas triwulan sebelum dan setelah dimulainya merger dan/atau akuisisi. Variabel input-output yang digunakan untuk DEA adalah dana pihak ketiga, aset tetap, dan Non-Interest Expense sebagai input dan total pinjaman serta Other Operating Income sebagai output. DEA menghasilkan bahwa skor efisiensi pada pasca-merger relatif lebih efisien daripada pra-merger. Model regresi Tobit digunakan untuk menentukan faktor-faktor yang mempengaruhi efisiensi bank dan kami mencatat untuk pra-merger bahwa bank size (TA), ROA dan NPL berpengaruh signifikan terhadap efisiensi bank. Namun untuk pasca-merger, bank size (TA), CAR dan ROA berpengaruh signifikan terhadap efisiensi bank.

Judul: Excretory/secretory antigen of ascaridia galli L3 stage to trigger yolk immunoglobulin in laying hens
Abstrak: Ascaridiosis caused by the nematode Ascaridia galli. A study was carried out to characterize excretory/secretory antigen of A. galli from larval stage to trigger anti-ascaridiosis yolk immunoglobulin in laying hens. A. galli L3 were recovered from intestines of 100 heads chickens 7 days after oesophagus inoculation with 6000 L2. L3 recovered in this manner were cultured (5 – 10 ml-1) in flasks containing rosswell park memorial institute (RPMI) 1640 media, pH 6.8, without phenol red. Cultures were incubated at 370C in 5% CO2 and culture fluid was collected after 3 days in culture. To prepare excretory/secretory antigen, culture medium were concentrated with vivaspin 30.000 MWCO, and antigen protein concentration were counted as described in Bradford method. The molecular weight of excretory/secretory antigen was determined with sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS PAGE). Active immunizations were applied intra muscularly of chickens with an initial dose of 80 μg. The immunizations were repeated three times with dose of each 60 μg with an interval of one week. The first immunizations were excretory/secretory antigen mixed with fruend adjuvant complete and subsequently mixed with freund adjuvant incomplete. The chicken’s eggs were collected from 49 day after immunizations. Anti-ascaridiosis yolk immunoglobulin (IgY) was extracted from egg yolks by means of ammonium sulphate and purified using fast performance liquid chromatography (FPLC). The purity of anti-ascaridiosis IgY was determined by Bradford method (λ = 280 nm). Antibody was detected by agar gel precipitation test (AGPT) and enzyme linked immunosorbant assay (ELISA). Antigen were detected with immunohistochemistry. Chickens were challanged with dose of 1000 L2 A. galli. Passive immunizations were applied ten times with dose of each 0,875 mg IgY with an interval of one day intra orally. IgY anti-ascaridiosis was tested against A. galli survival in vitro.
