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. The research also indicated that there was correlation between internal and external factors and network communication; correlation between communication network and farmers marketing behavior; and correlation internal and external factors and farmers marketing behavior.

Abstrak: Farmers need an adequate and trusted information in order to increase vegetable marketing. For fulfilling their information requirement, farmers establish a communication network among them. The purposes of this research were (1) to describe the communication network in price information and vegetable marketing among farmers (2) to analyze the relationship between personal characteristics of farmer and the communication network in price information and vegetable marketing. All members of Tani Jaya Farmer-Group, 21 farmers were taken as sample by using sampling intact system. This research resulted several outputs i.e: (1) communication network about vegetable price information was interlocking personal network and communication network about vegetable selling was radial personal network (2) there was significant relationship between arable land area, side job in addition to farming with local and global centrality of communication network about vegetable price information. There was also significant relationship between arable land area with global centrality of communication network about vegetable selling.

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.
