Judul: Kajian pengelolaan agroforestri dan konservasi keanekaragaman hayati
Abstrak: Presence of forest area which setted by government such as IUPHHK and nature reserve area are unable giving welfare to surrounding comunities. Deforestation is occur in that forested area which sooner or later will bringg the forest area to the point where unable to supply the wood demand. Non timber forest product is main product of agroforests in indonesia whereas timber forest product is the secondary product. Even so existence of community-owned agroforest more able giving walfare to the community and agroforest was estimated as an answer where the nature forest unable to supply the wood demand. Purpose of this research is to know the scheme of agroforest management and its benefits for community and biodiversity conservation. Research was held in Gunung Mananggel, Kecamatan Mande, Kabupaten Cianjur, West Java. Start by October 2009 till November 2010. Method that used was interviewing people arround the area and participative observation. the biodiversity research using vegetation analitic and making diagram profil of vegetation. Gunung Mananggel forested area consist of mosaics of few type of agroforest which at least consist of two canopy level. land of this area managed by farmers using agroforestry system. At least three types cyclical agroforest which indistinguishable exactly. that were durian agroforest, rubber plant agroforest and mixed agroforest. The benefit of this area to people especiallu farmers as a main source of livelihood such as source of fuelwood, woods supply, source of vegetables and complementary foods. Gunung Mananggel area has role to nature resource conservation as water catchment area and wildlife area. there are more than 39 species avifauna, two species primate and two another mammals.

Judul: Analisis Finansial Agroforestry di desa Cikanyere, Kecamatan Sukaresmi, Kabupaten Cianjur
Abstrak: Referring the condition of strategic planning of PKT duty, Kabupaten Cianjur, That is decreasion of critic area in Kabupaten Cianjur and development of people relization about what important the environment conservation is, so that rehabilitation of critic area program to return its function will be the one of program that must be done> As program basicly in people, the successness of this program is very influenced by local people participation. One of this program is Rehabilitation of Participative Forest and Field. This program can be done by agroforestry. Agroforestry is a way to manage the forest that in can improve agriculture production so that it can in crease the revenue and welfare of people arount the forest and to supply the needed that is more various. This research purpose for doing investigation about properness of agroforestry financial management

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.
