Judul: Analisis Leading Sector erhadap Penyerapan Tenaga Kerja di Kalimantan Timur dan Faktor-faktor yang Memengaruhinya
Abstrak: Economic growth in East Kalimantan is followed by a relatively high unemployment issue. Sectoral economic development is expected not only to increase Gross Regional Domestic Product (GRDP) but also increase employment level to face unemployment problem. In East Kalimantan, mining and quarrying sector contributes most to GRDP but isn’t able to provide high employments, while agriculture sector gives relatively small contribution to GRDP but could provide the highest employment. This study aims to analyze economic structure, analyze leading sector towards labor absorption, and factors influencing employment level in East Kalimantan. The analysis method used in this study is Input-Output Analysis and Ordinary Least Square method. The results show the agricultural sector is leading sector in labor absorption but isn’t able to increase output and income in east kalimantan. Leading sector in output is trade, hotels, and restaurants sector, while leading sector in income is services sector. Based on total output, income, and labor multiplier the agricultural sector is leading sector from that three aspects. Gross Regional Domestic Product (GRDP) and Regional Minimum Wage have a significantly positive impact to employment level, while domestic investment and foreign investment has a positive but insignificant impact to employment level in East Kalimantan

Judul: Analisis Peranan Sektor Pertanian dan Industri Pengolahan terhadap Perekonomian Propinsi Kalimantan Timur (Berdasarkan Analisis Input- Output)
Abstrak: Proses transformasi struktural yang tejadi di Indonesia maupun di Kalimantan Timur berimplikasi pada meningkatnya peran sektor industri yang menggeser peran penting sektor pertanian. Di sisi lain, sektor pertanian masih menduduki posisi yang strategis dalam penyerapan tenaga kerja serta produksi pangan sehingga tidak bisa diabaikan dan hams terus mendapat perhatian baik dalam perencanaan maupun pelaksanaan nasional dan regional. Mencermati hal tersebut adalah menarik untuk mencoba melihat dan menganalisis gambaran makro dari pembangunan Kalimantan Timur yang selama ini dilakukan, mengkaji keterkaitan sektor perekonomian (khususnya pada sektor pertanian dan industri pengolahan), mhhat pengaruh yang disebabkan oleh sektor pertanian dan sektor industri pengolahan terhadap keragaan perekonomian Kalimantan Timur. Gambaran hasil penelitian ini diharapkan dapat dijadikan bahan kajian untuk memperkaya khasanah penelitian yang berkaitan dengan pembangunan di Kalimantan Timur.

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.
