Judul: Pendugaan Manfaat Ruang Terbuka Hijau Dalam Pengendalian Aliran Permukaan Dengan Menggunakan Software Citygreen (Studi Kasus: Pulau Laut, Kabupaten Kotabaru, Kalimantan Selatan)
Abstrak: Perkembangan ruang kota di Pulau Laut menyebabkan terjadinya alih fungsi lahan dari ruang terbuka hijau menjadi kawasan permukiman dan perkebunan, sehingga berkurangnya kemampuan tanah menyerap air yang dapat menyebabkan ketersediaan atau akses terhadap air menjadi sulit. Penelitian ini bertujuan untuk mengetahui perubahan penutupan lahan pada periode tahun 2001-2012 dan menduga pengendalian aliran permukaan sehubungan dengan keberadaan RTH di Pulau Laut. Metode yang digunakan berupa metode deskriptif kuantitatif dengan analisis Sistem Informasi Geografi (SIG) yang dikombinasi dengan ekstensi CITYgreen 5.4 dalam menduga manfaat kanopi pohon dalam pengendalian aliran permukaan. Hasil penelitian ini menunjukkan bahwa luas hutan mengalami penurunan selama 11 tahun (2001-2012). Berdasarkan analisis, keberadaan ruang terbuka hijau di Pulau Laut Timur, Utara, Barat dan Selatan masing-masing sebesar 65%, 66%, 69%, dan 64% mampu menyimpan biaya pembangunan infrastruktur buatan untuk mengendalikan aliran permukaan masing-masing sebesar Rp 501 381 065 618, -, Rp 110 930 546 437, Rp 47 724 362 364, - dan Rp 72 151 535 796, -. Berdasarkan perhitungan regresi berganda, luas ruang terbuka hijau berupa lahan pertanian memiliki pengaruh yang signifikan terhadap nilai jasa lingkungan sebesar 57.70%.

Judul: Rancang bangun sistem pengelolaan ruang terbuka hijau untuk pembangunan kota hijau
Abstrak: Greenery open space is a fundamental part of urban development and management in sustaining the quality of urban environment and the welfare of urban dwellers. A high rate of population growth and limited land owned causing the growth of physical development in the city is done by converting such green open space, agricultural land, forest and other open space for urban development purposes. This study is intended to analyze total value of greenery open space ecological benefits of Bogor City, and provide possible recommendations in order to increase the capacity of its urban ecosystem. This analytical framework is applied to Bogor City considering its peculiarities of greenery open space existence and architectures. The research was conducted by spatial approach through CITYGreen 5.4 software to determine the ecological benefits of greenery open space, based on the trees canopy cover and non trees canopy cover to predict the economic value. CityGreen is a software tool developed by American Forest that helps people understand the value of trees to the local environment. The result showed that CITYGreen 5.4 software can be used to conduct complex analysis of ecosystem services and create easy to understand reports.The software calculate dollar benefits for the services provided by the trees and other greenery open space in absorbed such harmfull pollutants, carbon storage and sequestration, and reducing storm water volumes as natural flood control. The capacity of ecological benefit can still be improved to provide greater benefits in various ways. This software will be very beneficial for city planners in evaluate site plan, and model development scenario that capture the benefits of trees.

Judul: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
