Judul: Peramalan Net Asset Value Asuransi Unit Link Menggunakan Fuzzy Time Series Model Chen dan Modifikasinya
Abstrak: Asuransi unit link adalah produk asuransi yang dapat memberikan manfaat perlindungan bagi pemegang polis dan manfaat investasi berupa reksa dana dengan portofolio instrumen investasi. Nilai aset bersih pada suatu instrumen investasi dapat berfluktuasi disebabkan kondisi pasar modal pada waktu tertentu yang mana berdampak pada potensi keuntungan dari pemegang polis. Dalam hal ini, peramalan dapat dilakukan untuk memprediksi nilai aset bersih di masa yang akan datang. Pada karya ilmiah ini, metode peramalan yang digunakan adalah fuzzy time series model Chen. Metode peramalan fuzzy time series model Chen juga dapat dimodifikasi dengan menggunakan rata-rata terbobot. Berdasarkan hasil penelitian, hasil peramalan dengan metode fuzzy time series model Chen yang dimodifikasi memiliki hasil yang lebih akurat dibandingkan dengan metode fuzzy time series model Chen tanpa modifikasi. Hal ini ditunjukkan dengan nilai Mean Absolute Percentage Error (MAPE) dari metode fuzzy time series model Chen yang dimodifikasi lebih kecil daripada nilai MAPE dari metode fuzzy time series model Chen tanpa modifikasi., Unit link insurance is an insurance product that can provide policyholders with both protection and investment benefits in the form of mutual funds with a portfolio of investment instruments. The net asset value of an investment instrument can fluctuate due to capital market conditions at a given time, which affects the policyholder's potential profit. In this case, forecasting can be used to predict the net assets value in the future. The forecasting method used in this scientific work is the Chen model fuzzy time series forecasting method. The Chen model fuzzy time series forecasting method can also be modified by using with a weighted average. Based on the research results, the forecasting results using the modified Chen model fuzzy time series method have more accurate results than the Chen model fuzzy time series method without modification. This is indicated by the value of the Mean Absolute Percentage Error (MAPE) of the modified Chen model fuzzy time series method, which is smaller than the MAPE of the Chen model fuzzy time series method without modification.

Abstrak: This research was aimed to identify the bacteria which lived in the digestive tract of the indo-pacific bottlenose dolphin (Tursiops aduncus). Anal swab samples were taken from 11 clinically healthy dolphins. These samples were cultured in the blood agar and MacConkey agar. The identification of the bacteria were based on series of tests i.e., colony and individual morphology, Gram stain characterisic, and standard biochemistry tests. At least, 14 genus of bacteria were identified such as Edwardsiella, Actinobacillus, Serratia, Enterobacter, Alcaligenes, Morganella, Proteus, Moraxella, Aeromonas, Pseudomonas, Streptococcus, Staphylococcus, Listeria, and Bacillus. Serratia and Alcaligenes were the most common genus which were found in the digestive tract of the dolphin
