Judul: Konsep jalur hijau jalan di Kota Tangerang
Abstrak: Telah dilakukan penelitian perencanaan jalur hijau jalan di Kota Tangerang Provinsi Banten Kota Tangerang merupakan kota besar di Indonesia yang mengalami dampak buruk dalam penataan ruang sehungga kualitas lingkungan Kota Tangerang mengalami penurunan baik dari suhu udara maupun kualitas udaranya. Penggunaan wilayah pada Kota Tangerang harus mempertimbangkan penataan ruang yang baik dalam pemanfaatan ruang sebagai jalur hijau. Penelitian perencanaan jalur hijau jalan ini dilakukan di tiga penggunaan lahan meliputi wilayah industri, perdagangan dan pemukiman yang tersebar di Kecamatan Batu Ceper, Tangerang dan Cipondoh. Dari hasil penelitian menyatakan bahwa pemanfaatan jalur hijau jalan di wilayah tersebut belum dimanfaatkan secara optimal. Hal ini terlihat dari belum teraturnya jarak penanaman, kurangnya tanaman, tanaman yang tidak terawat dan tanaman mati. Hasil penelitian ini menunjukkan perlunya perubahan perencanaan di beberapa titik jalur hijau jalan di Kota Tangerang sehingga manfaat jalur hijau jalan dapat meningkatkan kualitas lingkungan.

Judul: Evaluasi Penerapan Konsep Kota Hijau di Kota Tangerang
Abstrak: Development of urban areas grew rapidly. Increasing physical development of the city cause the imbalance between urban growth and the attempt to increase the quality of the environment. The condition makes an uncomfortable city to live. Therefore the future urban planning could be directed to use the green city concept. Green city is a healthy city that considers the aspects of ecological planning. This research was conducted in Tangerang city by using Gap Analysis to find out the actual condition in applying the concept of green cities and comparing it with the ideal condition. The evaluation showed that implementation of green city concept in Tangerang city was still continue. It could be seen from the implementation of eight indicators of green city which had not been maximized, and spreaded through the region.

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.
