Judul: Comparison Scenario of Existing Conditions and Potential Areas for the District's Proliferation of Sukabumi Regency, West Java Province
Abstrak: Berdasarkan tingkat perkembangan dan karakteristik wilayahnya, Kabupaten Sukabumi dapat dibedakan menjadi dua bagian, yaitu Sukabumi bagian Utara dan Sukabumi bagian Selatan, dengan luas wilayah mencapai 416.404 ha, Sukabumi menjadi Kabupaten terluas se-Jawa dan Bali. Hal tersebut dijadikan alasan kurang optimalnya kinerja pemerintah dalam peningkatan kesejahteraan masyarakat, sehingga muncul rencana pemekaran wilayah di Kabupaten Sukabumi menjadi 3 Daerah Otonomi Baru (DOB), yaitu Kabupaten Sukabumi Utara, Sukabumi Induk, dan Pajampangan, serta rencana pemekaran 2 DOB yaitu Kabupaten Sukabumi Utara, dan Kabupaten Sukabumi Induk. Kabupaten Sukabumi memiliki lahan pertanian yang luas dengan berbagai komoditas pertanian yang berpotensi untuk dikembangkan. Dengan demikian, seharusnya sektor pertanian di Kabupaten Sukabumi dapat digunakan sebagai penggerak ekonomi daerah sehingga dapat menciptakan pertumbuhan dan mengurangi ketimpangan wilayah. Penelitian ini bertujuan untuk: (1) menganalisis tingkat perkembangan wilayah dan ketimpangan pembangunan pada wilayah rencana pemekaran; (2) mengidentifikasi potensi dan komoditas unggulan pertanian di wilayah rencana pemekaran berdasarkan keunggulan komparatif dan kompetitif; (3) menganalisis luas lahan tersedia untuk pertanian; serta (4) membandingkan potensi wilayah rencana pemekaran Kabupaten Sukabumi. Tingkat perkembangan wilayah dan ketimpangan pembangunan pada penelitian ini dianalisis dengan metode skalogram dan Indeks Theil Entropy. Analisis potensi dan komoditas unggulan pertanian dilakukan dengan metode Location Quotient (LQ) dan Shift Share Analysis (SSA). Analisis luas lahan tersedia untuk pertanian dilakukan dengan meng-overlay-kan peta penggunaan lahan dan peta pola ruang RTRW Kabupaten Sukabumi. Sementara itu, perbandingan potensi wilayah rencana pemekaran Kabupaten Sukabumi diuraikan secara tabulasi-deskriptif berdasarkan output dari analisis pada ketiga tujuan sebelumnya. Hasil penelitian menunjukkan adanya perbedaan kondisi eksisting dan potensi wilayah (termasuk pertanian) yang signifikan baik pemekaran 3 DOB maupun 2 DOB, khususnya antara wilayah bagian Utara dan Selatan. Pengembangan wilayah untuk rencana pemekaran 3 DOB, wilayah rencana pemekaran Kabupaten Sukabumi Utara dan Kabupaten Sukabumi Induk lebih pada pengembangan sektor non pertanian, sedangkan untuk wilayah rencana pemekaran Kabupaten Pajampangan lebih pada pengembangan sektor pertanian. Sementara itu, untuk pemekaran 2 DOB wilayah rencana pemekaran Kabupaten Sukabumi Utara tetap pada pengembangan sektor non pertanian, sedangkan untuk wilayah rencana pemekaran Kabupaten Sukabumi Induk dapat mengembangkan sektor non pertanian dan sektor pertanian sekaligus., Based on development and regional characteristics, Sukabumi can be divided into two parts, namely the northern of Sukabumi and the southern of Sukabumi, Sukabumi Regency is the largest regency in Java and Bali (414.404 ha). This (larges area) is used as the reason for the government's less than optimal performance in improving the welfare of the community. There are options for regional proliferation plans, into 3 New Autonomous Regions (DOB), namely North Sukabumi, Sukabumi Induk, and Pajampangan Regencies, and plans for 2 New Autonomous Regions, namely North Sukabumi Regency, and Sukabumi Induk Regency. Sukabumi Regency has extensive agricultural land with various agricultural commodities that have the potential to be developed. Thus, the agricultural sector in Sukabumi Regency can be used as driving for the regional economy, to create growth and reduce regional inequality. This study aims to: (1) analyze the level of regional development and development inequality in the proliferation plan areas; (2) identify potential and superior agricultural commodities in the proliferation plan areas based on comparative and competitive advantages; (3) analyze the area of

Judul: The Regional Development Study of Sukabumi City
Abstrak: In regional development process, Sukabumi city is quite successful in increasing the rate of economic growth, but get problem in the distribution of development between sub-districts. Disparity of sub-districts allegedly due to the changed of administrative boundaries that the new districts which are joined recently have not similar development with the old districts. Disparity between regions can cause lagging or underdeveloped areas which if not properly handled through government policy, can cause various problems that can obstruct the development of the area itself. Therefore need a study and identification of the policy directives of regional development. It is important in the formulation of regional policies to create equitable development in order to develop Sukabumi City. Based on the issue formulation, the study aims to: (1) analyze the level and the decomposition of regional development disparities in Sukabumi City, (2) identify potential economic sectors in each sub-district in Sukabumi, (3) determine the level of economic development and their hierarchy in each subdistrict in Sukabumi, (4) Find out the stakeholder’s perception on regional development priorities of Sukabumi, and (5) reviewing regional development policy directives in Sukabumi. Data used in this study are primary data and secondary data. The primary data obtained through interviews and questionnaires to the respondents/stakeholder, while secondary data include: (1) Potency of villages (PODES) in 2011, (2) GDP, and (3) Administrative of Region Map. Data obtained from Bappeda Sukabumi, the Central Statistics Agency (BPS), and other relevant department/agency/authorities. Analyzing methods used are the Williamson index and Theil index for decomposition and determines the level of disparity, LQ and SSA to identify potential sectors of the economy, Entropy and schallogram to determine the level of development of the region, the AHP to determine priorities for regional development and descriptive method to determine the regional development policy directives of Sukabumi. Based on the disparity analysis, there are regional disparities in Sukabumi at a medium level/uneven. Even, in the period 2007 to 2011 the level of disparity in Sukabumi has increased. This means that the development has been done so far has not been effectively create equity between regions in Sukabumi. To overcome this problem, it is necessary to arrange regional development directives based on the potential of economic sector and level of development of each region. Based on the analysis of LQ is note that each districts in Sukabumi has a basic sector. Based on the SSA analysis is note that Sukabumi has rapid growth in the Construction and Building Sector, Tradings, Hotels and Restaurants Sector, and Transportations and Communications Sector. With the regional development analysis is note that Baros, Cibeureum and Lembursitu districts are the area that need to be prioritized to be developed because these three regions have the lowest level of development and underdeveloped. Directions of regional development policy of Sukabumi should be done according to the level of regional development which are divided into a node and its hinterland. Both of these two regions should be directed to the mutual interaction, which enhances the development between regions in Sukabumi. The results of the analysis and synthesis of LQ and

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
