Judul: Analisis Ketersediaan Ruang Terbuka Hijau dan Tingkat Perkembangan Wilayah di Kota Cimahi Provinsi Jawa Barat
Abstrak: Environmental quality of cities and regencies degrade continuosly and they are worsened by the declining of greenery open space acreage. It is due to population growth and increasing demand of land for settlements and facilities development. Cimahi turned into a municipality in 2001. Since the beginning, Cimahi developed intensively, nonetheless balance condition of social and economic should be maintained carefully. One of the environmental aspects is greenery open space composition. This research aims to describe land use change process, to identify the availability of greenery open space, to understand the dynamics of developmental process of Cimahi Municipality, and to determine factors affecting the availability of greenery open space of Cimahi Municipality. During 2007-2011 total land of Cimahi Municipality changed as much as 420.6 hectares turned into settlements. The availability of greenery open space in Cimahi in 2011 was 738 hectares or 17.9% of the total area which was not sufficient for the total population of Cimahi Municipality. Cimahi showed unequally developed, some regions consistenly stayed at the same level of hierarchy by the time, while others were fluctuated. Factors affecting the availability of greenery open space in Cimahi were allocation of building land in the regional spatial plan (RTRW), population density, amount of type facilities, population growth, and built up land in 2011

Judul: Analysis of Availability of Green Open Space in Cibitung of Bekasi District Using SPOT-7 Imagery 2019
Abstrak: Kecamatan Cibitung merupakan bagian wilayah Kabupaten Bekasi yang perkembangannya berfokus pada kegiatan sosial dan ekonomi, sehingga perubahan pemanfaatan lahan untuk permukiman cukup pesat. Syarat suatu kawasan perkotaan adalah memiliki luas Ruang Terbuka Hijau (RTH) minimal 30% dengan proporsi 20% RTH Publik dan 10% RTH Privat dari luas wilayahnya menurut Permen PU No. 5 Tahun 2008. Tujuan penelitian adalah untuk mengetahui luas aktual RTH di Kecamatan Cibitung menggunakan citra satelit resolusi tinggi SPOT-7 tahun 2019 dengan metode analisis interpretasi visual menggunakan digitasi on-screen. Hasil penelitian menunjukkan Kecamatan Cibitung memiliki luas RTH Publik 537,029 ha atau 12,245% dan luas RTH Privat 360,158 ha atau 8,212% sehingga luas total RTH di Kecamatan Cibitung tahun 2019 adalah 897,187 ha atau 20,457% dari luas wilayahya. Sabuk hijau berupa sawah yang seluruhnya berada pada bagian utara Kecamatan Cibitung merupakan RTH dengan luas terbesar yaitu 2.018,008 ha atau 10,389%., Cibitung is a sub-district located in Bekasi District that focus in social and economy activity which is effect to land use conversion for housing rapidly. Urban area must has 30% green open space area from its area with the proportion 20% of public green open space area and 10% of private green open space area based on Permen PU No. 5 Tahun 2008. The research aim to find out actual area from green open space area in Cibitung on high resolution satellite imagery SPOT-7 that recorded in 2019 using visual interpretation analysis with screen digitizing method.

Judul: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
