Judul: Analysis of Structure Change and Sources of Economic Growth in DKI Jakarta: Input Output Model Analysis
Abstrak: This study aims to analyze the role of industrial sector in economic growth of DKI Jakarta Province in 1993, 2000, and 2006. This research is expected to provide information about what sector is superior sector (keysectors) and changes in economic structure in the Province of DKI Jakarta during study period. In addition, through this research could also determine that there are linkages among sectors in the Province of DKI Jakarta and the pattern of changes in sources of output growth. Research method used is the input-output analysis in order to answer the research objectives. Data of Input Output Table of DKI Jakarta Province obtained from BPS (Central Bureau of Statistics) is the data in 1993, 2000, and 2006. The number of sectors that were analyzed and then made the process of aggregation of up to 23 sectors. The results showed that during 1993, 2000, and 2006, the structure of domestic final demand is dominated by the demand among. Components of demand among the source of output growth is the component of household consumption (konsRT) and fixed capital formation (Pmtb). During the study period, sectors that have backward linkages rates above the average power dispersion and that have numbers forward linkage in the above-average sensitivity of dispersion has decreased the number of sectors. Based on the analysis, leading sector during the study period occurred in six sectors, namely; industry sector of Food, Beverages & Tobacco (MKMN), sector of Chemical, Drugs, Cosmetics (KIMOB), sector of Metal, Machinery, and Electronic (LME), sector of Electricity, Gas, and Water Supply (LGAB), sector of Real Estate, and Business Services (REJP), and sector of Other Services (JSLN).

Judul: Analisis Tabel Input Output Sembilan Sektor Ekonomi DKI Jakarta Tahun 2000
Abstrak: Arus barang dan jasa antar seldar ekonomi dalam suatu perekonomian selama periode waktu tertentu dapat digambarkan dalam sebuah tabel input-()utput. Oalam penelitian ini dipelajari tentang t:ransaksi/keterkaitan antar sektor-sektor ekonomi di DKI Jakarta pada tahun 2000, penentuan sektorsektor yang mempunyai pengaruh kuat dan peka terhadap pertumbuhan ekonomi serta pengidentifilrnsian hal-hal yang menyebabkan penghitungan niIai tambah brutn pada data PORB Propinsi OK! Jakarta mengbasilkan angka yang berbeda dengan tabel input-output regional. Tr.msaksiIketertan antar sektor serta peringkat sektor dianaUsis dengan menggunakan analisis deskriptif dan analisis dampak, sf'ilangkan peIbedaan nilai tambah bruto pada PORB dengan tabel inputoutput DKJ Jakarta tahun 2000 dijelaskan dengan melakukan perbandingan. Dari basil analisis tabe1 input-output sembilan seldor ekonomi, terlihat bahwa sektor yang belum mampu mencukupi penniotaan baik penninra3n antara maupun akhir adalah sektor industri pengoIaban dan sel"tor pertanian, sehingga barns mengimpor. Kemudian sektor yang mampu memberikan niw tambah bruto terbesar adalah seldor perdagangan-hote1-restoran. Apabila ditinjau dati efisiensi penciptaan output, maka sektor pcrtanian adalah yang paling cfisien. Sementara apabila dilihat dari pcnyerapan tenaga kerja, maka sektor perdagangan-botel-restoran dan sektor jasa-jasa adalah sektor yang memiliki efektifitas penyerapan tenaga kelja tertinggi dibanding seldor lainnya Sektor induslri pengolahan, sektor perdagangan-hote1-restoran dan sektor keuangan-persewaan-jasa perusahaan adalah sektor yang memiliki daya dorong yang kuat bagi perekonomian OK! Jakarta. Selanjutnya, dati basil perbandingan antara PORB dengan label input-output OKI Jakarta rabun 2000, dapat diketahui beberapa hal yang menyebabkan perbedaan nilai tambah bruto, antara lain: metode yang d.igunakan. swnberlketersediaan data, cakupan, waktu dan biaya. Karena hal-hal tersebut maka data nilai tambah bruto pada PORB menjadi kerendahan. Oleb karena itu para pengguna data PORB sebaiknya berhati-hati apabila ingin menggunakan data PORB

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.
