Judul: The main factors of land use in the area of food production centre of Siak, Siak District Riau Province.
Abstrak: Food security is one of the important factor in development Province. According ti this, Riau Government determine five centre food production area. One of those centre is food production centre of Siak, which population are recolation community from Java and local community from Malay. The aim of this research were (1) Evaluate land suitability to each land use and opportunity for change land use at KSp Pangan Saik (2) to determine the main factor of land use at KSP Pangan Siak.

Judul: Identifikasi lahan potensial untuk mendukung usulan perencanaan lahan pertanian pangan berkelanjutan
Abstrak: The passing of Law 41, 2009 on the Protection of Sustainable Food Farming Land (PSFFL) is expected to control the pace of agricultural land use change in particular fields. This law is still new so that many of its implementation have not been done, including the planning and establishment of regions, prime land and reserve land. West Java Province is the province's second-largest contributor to the national rice with the support of a potential wetland. Spatial analysis can be used to determine the potential of component sustainable food farming in province based on data and supporting information. The purposes of this study are (1) To analyze the projection needs of wetland at the provincial and district levels, (2) To identify potential land for prime sustainable food farming land and reserve sustainable food farming land at the provincial and district levels, (3) To define potential locations for the proposed as the sustainable food farming region at the provincial and district levels. The results show that the availability of land is the main deciding factor, otherwise suitability of land has not influence in deciding of sustainable food farming area. At the provincial level, the result shows that more general planning area proposed, including assemblage of some small regions, and indication of prime and reserve land. The proposed planning at the provincial level is a reference in the preparation of the proposed planning district, with more a detail data for regions, prime and reserve land along with prediction size of area.

Judul: Sifat optik dan sifat listrik diode schottky film Barium Titanat (BaTiO3) berstruktur emas - BaTiO3 (Metal – ferroelektrik)
Abstrak: Diode Schottky (emas - BaTiO3) berhasil dibuat dengan ditumbuhkan di atas permukaan interdigital electrode berbahan emas(Au) menggunakan metode Chemical Solution Deposition (CSD) . Film BaTiO3 dibuat dengan proses annealing pada suhu 400oC dengan variasi holding time annealing 4 jam dan 10 jam. Karakterisasi sifat optik diode Schottky dilakukan menggunakan UV-Vis Spektrofotometer untuk memperoleh nilai energi gap Film BaTiO3. Nilai energi gap BaTiO3 pada dua perlakuan holding time annealing 4 jam dan 10 jam sebesar 3.27 eV dan 3.21 eV dan nilai energi gap tersebut termasuk dalam kategori semikonduktor. Karakterisasi sifat listrik diode Schottky dilakukan menggunakan LCR Meter yang didapatkan nilai konduktivitas listrik pada Holding time annealing 10 jam lebih besar daripada 4 jam. Kemudian, didapatkan nilai impedansi yang menunjukkan bahwa pada holding time annealing 4 jam lebih besar daripada holding time 10 jam. Didapatkan pula nilai konstanta dielektrik yang menunjukkan pada waktu holding time annealing 4 jam lebih besar daripada 10 jam.
