Judul: Potensi Ruang Terbuka Hijau Dua Perumahan di Kecamatan Bogor Barat untuk Konservasi Eks-Situ
Abstrak: Green Open Space (GOS) of housing is potential for ex-situ conservation. This study aims to determine the diversity potential of GOS vegetation on two housings (Griya Melati Housing and Pakuan Regency) in West Bogor District for ex-situ conservation. Exploratory method was used to observe GOS for public and random sample method for GOS on home gardens. The residents and housing officials interviews were used to support the research data. The number and diversity of GOS plants in Griya Melati were bigger than Pakuan Regency. It was because of the residence time in the housing, housing regulations, and residents interaction with GOS plants. There were 14 species (CITES), 8 species (IUCN), or 2 species (PP No.7 Year 1999) of protected plants that found on GOS. Awareness of the importance of ex-situ conservation of each person is one of important factor in variations in the number and diversity of GOS plants of housing. The higher a person's awareness in preserving plant, the higher the interaction with the plant. This leads to increase the insights on conservation and make the ex-situ conservation as a form of preservation of germplasm, particularly endangered plants.

Judul: Dinamika perubahan penggunaan lahan dan strategi pengalokasian ruang terbuka hijau berdasarkan penganggaran daerah berbasis lingkungan (studi kasus Kota Bekasi)
Abstrak: Marginalization issue of Green Open Space (GOS) with a high level of land conversion from vegetative or agriculture land to built land in urban area shows that there is no commitment of regional government on a sustainable urban development. Political commitment on the regional government is indicated among others by the weak support of green regional budgeting (APBD) related to GOS. The research was conducted in Bekasi City. The purpose of this research was to determine a model of environmentally sound regional budgeting policy strategy related for allocation of public GOS by using a hard systems and a soft systems approaches. The former was conducted by landuse changes analysis with the factors influencing them, by designing a regional budgeting based on GOS allocating model structure by using a dynamic system approach by formulating the direction policy using focus group discussion (FGD) and analytical hierarchy process (AHP). The results of landuse change analysis showed that there was an increase in built land area from 5.5% (1,157.77 ha) in 1989 to 70.7% (14,879.85 ha) in 2009. The determinants of landuse changes in GOS were population, educational facilities, markets, supermarkets, settlements, industries, restaurants, hotels, and inns (R2 = 99.6%). The dynamic model was designed three scenarios of GOS allocating policy strategy (pessimism, moderate, and optimism) with an early simulation in 2010. The optimism scenario was considered as being capable of accommodating the fulfillment of city GOS need really on an assumption of considerable long multiyears budgeting so that in 2030 the target of 20% public GOS would be achieved. The results of analysis by AHP and FGD approaches showed that alternatives were on 2 main policies, namely: agriculture/GOS infrastructure development and GOS land acquirement. The priorities of policies emphasized the importance of commitment to green budgeting with tight control, particularly tax disincentive and tightening of building license.

Judul: Variasi Waktu Reaksi Sintesis terhadap Karakteristik Struktural Nanoplatelet α-Zirkonium Fosfat
Abstrak: Nanoplatelet α-ZrP merupakan material anorganik yang bersifat asam dan berstruktur kristal dengan rumus Zr(HPO4)2.H2O. α-ZrP disintesis dengan ragam waktu reaksi hidrotermal selama 3, 6, 12, 18, dan 24 jam untuk megevaluasi pengaruh waktu reaksi sintesis pada morfologi, ukuran partikel, dan kapasitas tukar kation (KTK). Spektrum inframerah nanoplatelet α-ZrP dari kelima ragam waktu tersebut menunjukkan keberadaan ikatan O-H, P-OH, P-O, dan PO4. Difraksi sinar-X memperlihatkan terdapat empat puncak 2θ yang serupa dengan pola difraksi standar α-ZrP dari data JCPDS. Payaran mikroskop elektron menampilkan bahwa material α-ZrP berukuran nanometer pada bagian ketebalan partikelnya dan berbentuk platelet yang pipih. Nanoplatelet α-ZrP memiliki rentang distribusi ukuran partikel yang luas. Perbedaan ukuran disebabkan oleh ragam waktu dalam proses hidrotermal. Ukuran partikel semakin besar seiring lamanya proses hidrotermal. Penentuan KTK menunjukkan semakin lama waktu sintesis maka semakin kecil nilai KTK.
