Judul: Difusi inovasi telepon seluler di perdesaan (kasus desa Kemang Bojongpicung, kabupaten Cianjur, provinsi Jawa Barat)
Abstrak: By referring to the diffusion of innovation theory, this study found that the adoption rates of mobile phone among the adopters in the two hamlets are low; it is about 28 per cent and 17 per cent for Beber and Cikupa hamlets respectively. Although the mobile phone exposure of Kemang Village community started about 15 years ago, the majority of people in Kemang Village adopted the mobile phone since the Base Transceiver Stations (BTS) of XL and Telkomsel were constructed in this village, in 2008 and 2010 respectively. The plot result of mobile phone adopter of the two hamlets was in S Curve shape. On the other hand, as not all the mobile phone adopters of the two hamlets were surveyed, the mobile phone adopters’ categories are not in normal distribution. It caused the plot of adopters categories is not in Bell-shaped curve. Therefore, the distribution of the mobile phone adopter categories did not support the theory of adopters’ category as stated by Rogers and Shoemaker (1971). However, this study supported another Rogers and Shoemaker’s generalization with regard to the fact that the individual characteristic of innovator category is higher than that of the other adopters’ categories. There are each four independent variables which significantly related to the rate of innovativeness as well as adoption rates at the significance level of 0.05. The independent variables which related to innovativeness rate were the level of relative advantage, the individual integration level, the formal educational level and the level of individual need toward the mobile phone innovation, while for the adoption rate were the level of observability, the interpersonal communication individual level, the meeting frequency, and the promotion of mobile phone agency/seller. There were five of nine mobile phone use patterns which developed dominantly by the adopters in the two hamlets, especially phone call/text messages to: the nucleus family (22,67 per cent) peer group and the combination of peer group and business partner, and distance relatives (each 17,33 per cent), only distance relatives (16 per cent), as well as phone call/text messages to business partner only, and the combination of nucleus family and peer group (each 9,33 percent). It seems that this mobile phone use patterns caused the irrational over adoption of mobile pone is dominant, especially for those who used the mobile phone only for consumptive activities.

Judul: Pemurnian Minyak Ikan Sardinella sp. dengan Proses Winterisasi
Abstrak: Minyak ikan Sardinella sp. memiliki komposisi asam lemak yang didominasi oleh asam lemak jenuh yaitu asam palmitat 20,25%. Hal tersebut dapat diturunkan dengan dilakukan pemurnian melalui 4 tahap yaitu degumming, netralisasi, bleaching, dan winterisasi. Penelitian ini bertujuan untuk menghasilkan minyak ikan murni menggunakan perlakuan suhu winterisasi pada minyak ikan yang telah dimurnikan terlebih dahulu dengan perlakuan kecepatan sentrifugasi pada degumming garam dan konsentrasi adsorben. Minyak ikan murni dengan kualitas terbaik didapat pada perlakuan kecepatan sentrifugasi pada degumming garam 10.000 rpm, konsentrasi magnesol 1%, suhu winterisasi 4 °C, yaitu memiliki kadar asam lemak bebas 0,75%, bilangan peroksida 5,16 meq/kg, bilangan asam 1,63 mg KOH/g, bilangan p-anisidin 12,87 meq/kg, total oksidasi 23,19 meq/kg, tingkat kejernihan 39,15%. Minyak ikan sebelum proses winterisasi memiliki kadar asam lemak jenuh sebesar 35,22%, kemudian turun menjadi 31,06% setelah proses winterisasi.
