Judul: Tingkat Kinerja Penyuluh Kehutanan di Kabupaten Bogor
Abstrak: This study aimed to explain the performance level of forestry extension agents in Bogor district and the relation between internal and external factors to the performance level of forestry extension agents. Forestry extension agents and farmers were as units of analysis in this study. Performance level of forestry extension agents assessed by farmers, while internal and external factors were assessed by the extension agents themselves. The performance level of all the forestry extension agents were in the low category. The factors related to low levels of forestry extension agents’s performance are not identified.

Judul: Persepsi penyuluh kehutanan dan petani terhadap hutan rakyat di Kabupaten Bogor, Jawa Barat
Abstrak: Keberadaan hutan rakyat di Kabupaten Bogor sangat penting bagi kehidupan para petani karena keberadaannya menjadi sumber penghasilan bagi kehidupan sehari-hari. Penelitian ini bertujuan untuk menganalisis persepsi penyuluh kehutanan terhadap hutan rakyat dan menganalisis persepsi petani terhadap hutan rakyat. Persepsi penyuluh kehutanan terhadap pengetahuan dasar penyuluhan memiliki skor 80.80%, manajemen batas dan status lahan memiliki skor 68.50% dan pengembangan hutan rakyat memiliki skor 59.33%, pengaruh jenis tanaman dengan kesesuaian lahan memiliki skor 79.33%, materi penyuluhan memiliki skor 80.67% dan evaluasi penyuluhan memiliki skor 74.00% dan persepsi petani terhadap pengetahuan penyuluhan memiliki skor 86.20%, kesesuaian lahan dan faktor yang mempengaruhinya memiliki skor 68.00%, pengaruh kayu dengan pendapatan memiliki skor 75.00%, pengaruh jenis tanaman dan kesesuaian lahan memiliki skor 75.00% dan pengaruh hama dengan pertumbuhan tanaman memiliki skor 77.00% dan pengaruh kelangkaan pupuk dengan pertumbuhan tanaman memiliki skor 75.89%. Secara keseluruhan persepsi penyuluh kehutanan dan petani terhadap hutan rakyat termasuk dalam kategori baik dengan skor 74.20% dan 76.10% dikategorikan persepsi baik.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
