Judul: Rancang Bangun Cyber Extension Budidaya dan Agribisnis Belimbing Dewa (Averrhoa carambola L.)
Abstrak: The purpose of this study is to develop a cyber extension for starfruit commodities. This method includes the identification of the problem, searching source of knowledge, knowledge acquisition, knowledge representation and design cyber system extension. The system was built using several stages which includes the stages of analysis, design and implementation. The results of this research by cyber extension system agribusiness for starfruit cultivation consist of, consultation modules for information starfruit varieties, for controlling pest and disease, cultivation knowlegdes, economical analysis for farming, climatic conditions and starfruit information price. The prototype system has been implemented using PHP and MySQL and running properly in web base. The system performed test is located on starfruit farmers in Depok.

Judul: Evaluasi Sistem Cyber Extension Dalam Perkembangan Informasi Agribisnis
Abstrak: Cyber Extension is one of agricultural innovation communication network development mechanism wich is programmed effectively to gather research, development, and assessment institution with instructors, preceptors, farmers, and other stakeholders wich every each one has different information requirement resulting synergistic and complementary act. The aim of this study is to formulate development system strategy so that it can enhance the existing system. Analysis Method used in this study was Force Field Analysis, the purpose of using this method was to identify driving forces and resisting forces factor to determine the strategy that strengthen the driving forces and weakend the resisting forces. Based on Force Field Analysis, the number of driving factor is determined to be bigger than resisting factor, wich equal to 5,07.

Judul: Karakteristik Piezoelektrik Film LaxSr₁-xTiO3 di atas Substrat TCO
Abstrak: Studi material perovskite SrTiO3 sudah banyak dilakukan dan menunjukkan sifat feroelektrik, piezoelektrik, kuantum paraelektrik dan superkonduktor yang baik. Dengan penambahan dopant La2O3 diduga menambah performa sifat piezo dan karakteristik lainnya. Karakteristik film LaxSr₁-xTiO3 (LST) dengan variasi x= 0, 0.02, 0.04, 0.06 terbentuk pada suhu annealing 550 oC di atas substrat TCO melalui metode (Chemical Solution Deposition) CSD dan spin coating dengan 700 rpm pada kondisi suhu ruang dan tekanan atmosfer standar. Hasil menunjukkan, semakin banyak pendadah La maka nilai ketebalan film, ukuran rerata kristalit, parameter kisi, transmitansi, nilai konduktivitas (maksimum 589.7 S/cm pada sampel x=0.04 di frekuensi 10 Hz), nilai konstanta tegangan (c) dan muatan (d) piezo semakin meningkat. Dinamika bentuk grafik nilai tegangan (V) dan konstanta regangan mekanik (s) nampak mirip. Nilai V mencapai 0.127 V untuk x=0.06 (beban 50 g). Nilai maksimum c, d, s masing-masing mencapai 20.07 Vm/N, 1.14x10-8 C/N, 13642.71. Nilai band gap untuk x=0, 0.02, 0.04, 0.06 masing-masing 3.21 eV, 3.1 eV, 2.6 eV, 2.4 eV. La2O3 menambah performa sifat piezo, sehingga LST berpotensi sebagai sensor tekanan.
