Abstrak: High-intensity of communication is necessary in a group, for example by build condusive climate communication. This study aimed to describe individual characteristics, animal husbandry characteristics, level of participation, communication climate, and cohesiveness level of Bina Tani Mandiri Farmers Group Members; to analyze the correlation between individual characteristics with supportive and defensive communication climate; the correlation between animal husbandry characteristics with supportive and defensive communication climate; the correlation between level of participation with supportive and defensive communication climate; and the correlation between supportive and defensive communication climate with cohesiveness level of Bina Tani Mandiri Farmers Group members. This study used quantitative approach which supported by qualitative approach. Thirty active members of Bina Tani Mandiri Farmers Group had become respondent in this study. The results showed that goals of group level had significant correlation with supportive and defensive communication climate. Besides, supportive and defensive communication climate also had significant correlation with cohesiveness level. In additon, this study showed that age level, educational attainment, main job, secondary job, goals of individual level, experience level, animal husbandry business’s scale, and complicity in the implementation, planning, and evaluation phase had no significant correlation with supportive and defensive communication climate of Bina Tani Mandiri Farmers Group members.

Judul: Pricing of Lookback Options with Floating Strike Price Using The Monte Carlo Method
Abstrak: Opsi lookback adalah opsi yang payoff-nya bergantung pada harga saham terbesar atau harga saham terkecil yang dicapai selama masa berlaku opsi. Opsi lookback dikatakan dengan floating strike price jika nilai dari strike price sebesar harga saham pada saat jatuh tempo. Nilai hampiran opsi lookback ditentukan dengan metode Monte Carlo, sedangkan nilai eksak didapat dari nilai simulasi terbesar yang mampu dihitung oleh komputer. Berdasarkan hasil penghitungan, nilai galat relatif yang dihasilkan semakin kecil dengan semakin bertambah banyaknya simulasi yang dilakukan, sehingga metode Monte Carlo untuk menghitung harga opsi lookback dengan floating strike price konvergen ke nilai eksaknya., Lookback option is an option whose payoff depends on the maximum or minimum of the asset price reached during the option period. The lookback option is said to be a floating strike price if the value of the strike price is equal to the stock price at maturity. The value of the lookback option is determined by the Monte Carlo method, while the exact value is obtained from the largest simulation value that the computer can compute. Based on the calculation results, the resulting relative error value get smaller with the increasing number of simulations performed. Therefore, the Monte Carlo method to calculate the price of the lookback option with the floating strike price converges to the exact value.
