Judul: Pemetaan Provinsi di Indonesia berdasarkan Lapangan Pekerjaan Utama dengan Analisis Korespondensi
Abstrak: In this mapped work, the provinces of Indonesia were on the basis of main job data population aged 15 years and older according to the main employment in 2003, 2005, 2008, 2009, 2010, 2011, and 2012. The configuration of provinces in 2008 and 2009 remained unchanged, with the biggest goodness-of-fit (GF) via Procrustes Analysis (GF = 98.38%). The largest changes on configuration occurred in 2005 and 2012 with the GF was found to be the smallest (GF = 82.92%). The most extreme changes occured in the Aceh Province, Southest Sulawesi, Lampung, and Gorontalo. Both Riau and Riau Islands Provinces which were a result of the expansion area have different characteristics. Riau Province was characterized by agriculture, forestry, hunting, fisheries, wholesale trade, retail trade, restaurants, and hotels while Riau Islands was manufacturing industry, wholesale trade, retail trade, restaurants, and hotels. Based on the GF value of correspondence analysis, the visualization in low dimension is able to explain the variation between 84.23% to 88.93% of the total inertia

Judul: Analisis Data Panel Anomali Penyerapan Tenaga Kerja Pertanian di Indonesia
Abstrak: Based on the survey results of the Badan Pusat Statistik, agricultural labor in Indonesia, reaching at 35.09% in 2012. However, during the years 2008 to 2012, the average employment in this period decreased by 1.49% while agricultural Gross Domestic Product increased at 0.05%. This case is not in line with the economic theory that explains that economic growth will boost employment and vice versa. This study was conducted to determine the province which is not in line and know the explanatory variables that affect the number of agricultural workers by using the data of 2008 to 2012 in 33 provinces. The results showed that 23 provinces in line and 10 other provinces are not in line. Ten provinces spread across the island of Sumatra, Java, Bali and Sulawesi. The explanatory variables that affect the amount of agricultural labor are the variable number of resident, the number of working-age population, the number of villages, and the amount of wages

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.
