This study used a Randomized Complete Design (RBD) with 2 factors. The first factor was the concentration of dextrin (10%, 14%, 18%, 22%) and the second factor was the concentration of tween 80 (0.3%, 0.4%, 0.5%) with the drying temperature of 70°C. The experiment was repeated three times. Observations were made every 2 hours until the sample weight did not decrease. Variables which observed were rate of drying, whiteness, yield, and pH of flour aloe vera. The results showed that concentrations of dextrin and tween 80 significantly affected water content, the degree of whiteness of the flour was affected by concentrations of dextrin. Treatment interaction between dextrin concentration and tween 80 did not significantly affect all parameters observed. The addition of dextrin will slow the drying process, on the contrary the addition of tween 80 will speed up the drying process. The highest yield at amount of 10.99% was obtained from the treatment interaction of 22% dextrin with 0.3% tween 80. The degree of acidity (pH) of the flour at 4.00 which was the highest value of pH was yielded form the treatment interaction of 10% dextrin with 0.5% tween 80. In this study, the best treatment resulting aloe vera flour that approaching the standards of quality of Terry Laboratories was a treatment interaction of 22% dextrin with 0.3% tween 80. The flour had a water content of 8.68%, the degree of whiteness 50.51, yield 10.99%, and the degree of acidity (pH) 3.65.

Tujuan penelitian ini yaitu mengetahui keterkaitan harga internasional kopi arabika dengan harga kopi arabika di tingkat produsen (petani) dan menentukan besaran premi serta nilai pertanggungan. Data yang dipergunakan yaitu harga internasional kopi arabika, harga kopi arabika tingkat produsen (petani), kurs mata uang IDR-US$, suku bunga Bank Indonesia, inflasi tahunan, dan data biaya produksi (input) usaha tani kopi arabika per tahun/Ha. Hasil analisis data menunjukkan bahwa harga internasional kopi arabika berkorelasi sangat kuat terhadap harga kopi arabika di tingkat produsen (r=0,87) pada bulan Nopember. Perubahan harga internasional kopi arabika (x) berpengaruh positif terhadap perubahan harga kopi arabika di tingkat produsen (y) yang dinyatakan dengan persamaan regresi linier sederhana 1,031x – 2282,150 (R2 = 0,7503). Hasil uji normalitas menggunakan metode Kolmogorov-Smirnov (K-S) menunjukkan log data harga internasional kopi arabika yang dijadikan basis indeks harga internasional berdistribusi normal (K-S=0,864), kemudian dilanjutkan dengan penentuan besaran premi dan besaran pertanggungan asuransi. Berdasarkan metode Black-Scholes terdapat enam pilihan nilai premi yang ditawarkan mulai dari persentil ke 5, 10, 15, 20, 25, 30 yaitu Rp. 226.781, Rp. 263.034, Rp. 293.666, Rp. 321.458, Rp. 347.470, Rp. 372.238 untuk nilai pertanggungan sebesar Rp. 19.539.567 tiap satu masa kontrak. Coffee is one of Indonesia's main export commodities. Arabica coffee farm business has a high risk of loss and the government is obliged to give protection to farmers in the form of subsidy of premium. The purpose of this research to know the procedure of pricing the value of the contract of arabica coffee farm business insurance based on international price index and the amount of premium and the sum of coverage. The data used are the international price of arabica coffee, the price of arabica coffee at the producer level (farmer), the exchange rate of US$ -IDR, the Bank Indonesia rate, the annual inflation, and the production cost of arabica coffee per year. The result of data analysis showed that the international price of arabica coffee is highly correlated to arabica coffee price at the producer level (r = 0,87). The international price change of arabica coffee (y) has a positive effect on the change of arabica coffee price at producer level (x) which is expressed by simple linear regression equation y = 1,031x - 2282,150 (R2 = 0,7503).
