Judul: Research is Communication Network Analysis of Aloe vera’s Farmer in the Central Agribusiness Area in Pontianak
Abstrak: The objectives of the research were: (1) to explain the diversity of communication network structure, (2) to explain the correlation between internal and external factors of communication and communication network, (3) to explain the correlation between communication network and farmers marketing behavior, (4) to explain the correlation between internal and external factors of communication and farmers marketing behavior. The respondents in the research was all of Aloe vera’s farmers, i, e., 67 person. The result of the research indicated that there were 7 (seven) respondents as stars, 4 (four) respondents as bridges, 2 (two) respondents as liaisons and 2 (two) respondents as isolates. There were 7 (seven) cliques in the system in which 5 (five) clique s take forms as radials or stars, 1 (one) clique as a circle form and 1 (one) clique takes form as all chanells.

Abstrak: Communication network analysis is one of method that can be used to identify the interaction of individuals with each other in particular group or with other parties outside the group, This method not only focused on the individuals and the social unit but also the quality of the relationship between social units. The aims of this study were, (1) Describe communication networks among farmers groups markets in Benteng Village, (2) Describe the communication network which formed among farmer groups in Benteng village and the role of the individual in the network structure, (3) analyze the correlation between individual characteristics and communication network, (4) Analysis the role of communication networks and the markets of crop collectors in improving the agricultural production of farmers in Benteng Village, and analyze the relationship between the communication networks and farmers marketing to their products. This study was conducted by utilizing qualitative and quantitative methods through semi-structured questionnaire and interviews for all farmers' groups members in Benteng Village, the analysis unit consisted of individuals which total 107 people, distributed into three groups of farmers who are member Gapoktan in Benteng Village, Ciampea, Bogor regency. In order to identify the communication networks, UCINET VI software was used in farmer network analysis, as well as correlation analysis using the Microsoft Excel through SPSS reinforced by data from SPSS 20 statistical tests. The results showed that the structure of communication network in the Gapoktan Tani Benteng form the structure of the wheel, and variable of individual characteristics such as age, the scale of business, are significantly related to the degree centrality. Relationship between farmer’s characteristics and communication network was a significant correlation at the level of 10% of the respondents with the communication networks and the value of -0.186, Thus, it can be said that the younger members of Gapoktan are the most centralized in the system and interested in using communication networks to communicate with other members of the other groups, while the older members are less he or she will interest in communication networks, on the other hand, members of old Gapoktan, or older than 65 years do not contribute much to activities of farming. The result showed that the correlation between communication network (Y1) and marketing (Y2) are significant, so, the coefficient between communication network and marketing Showing that, whenever were the communication rate highly among farmers, whenever were the marketing rate high., Analisis jaringan komunikasi merupakan salah satu metode yang digunakan untuk mengidentifikasi interaksi antarindividu dalam kelompok tertentu atau dengan pihak lain di luar kelompok tersebut. Metode ini tidak hanya berfokus pada individu dan unit sosial tetapi juga kualitas hubungan antarunit sosial. Penelitian ini bertujuan untuk: (1), mendeskripsikan jaringan komunikasi pemasaran kelompok petani di Desa Benteng, (2), mendeskripsikan jaringan komunikasi yang terbentuk di antara kelompok petani di desa Benteng dan peran individu dalam struktur jaringan, (3), menganalisis korelasi antara karakteristik individu dan jaringan komunikasi, (4), menganalisis peran jaringan komunikasi dan pasar pengumpul (tengkulak) dalam meningkatkan produksi pertanian di Desa Benteng, dan menganalisis hubungan antara jaringan komunikasi dan pemasaran produk pertanian oleh petani.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
