Judul: Desain Pocket Park Sebagai Solusi Ketersediaan RTH di Kawasan Perdagangan dan Jasa di Kota Bogor.
Abstrak: Pergerseran tata guna lahan dari ruang hijau menjadi lahan terbangun sering terjadi pada area-area komersial. Hal tersebut mengakibatkan sedikitnya ruang-ruang yang tersisa yang dapat dijadikan sebagai ruang terbuka hijau untuk sarana interaksi masyarakat. Pocket park merupakan salah satu bentuk dari RTH dalam skala yang kecil yang memanfaatkan ruang-ruang kosong dan tidak terpakai. Hal tersebut dapat dijadikan sebagai solusi ketersediaan RTH dengan memanfaatkan ruang-ruang yang tersedia.Meskipun dalam skala yang kecil,apabila diimplementasikan dalam jumlah yang banyak, pembangunan pocket park dapat membentuk sebuah jejaring hijau. Penelitian ini dilaksanakan Pandu Raya (Jalan Ahmad Adnan Wijaya) yang termasuk kawasan perdagangan dan jasa Kota Bogor. Melalui standar bentang jarak 500 meter (mengacu pada standar aksesibilitas pocket park menurut Visalia City Council), ditemukan 3 titik potensial tapak. Ketiga titik potensial tersebut kemudian dianalisis potensi serta kendalanya untuk dijadikan acuan dalam mendesain pocket park. Fokus desain adalah untuk memberikan rekomendasi yang adaptif terhadap ketersediaan ruang yang berbeda melalui pembagian tipe-tipe pocket park. Tipe pocket park tersebut terbagi kedalam tiga jenis yaitu, aktif, pasif, dan bonus.

Judul: Desain Jejaring Pocket Park Sebagai Ruang Resapan Air Hujan di Kota Bogor
Abstrak: Bogor as satelite city which has potential rain fall rates up to 3 000 – 4 000 mm/year may develop pocket park network through transect method to increase availability of society interaction space and rain infiltration area. Contained 331 potential spots as result of radial type network and able to increase green open space needed in Bogor up to 1.41 – 5.65% (based on Visalia City Council pocket park development standard size 1 012 – 4 046 m2). Pocket park network result shall be classtificated by nearest regional function to afford adaptable park. Designing proceed focused to provide pasif interactional space with aplicate of rain garden principle as rain infiltration area. Result of 4 different sample types (commercial, industrial, residential, and gevermential building) able to provide rain water reservoir with capability rates up to 342.2 – 706.4 m3. The practice toward 331 spots may provide rain water and run off reservoir in Bogor up to 113 268.2 – 233 818.4 m3.

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.
