Judul: Analisis Leading Sector Dan Faktor-Faktor Yang Memengaruhi Penyerapan Tenaga Kerja Di Provinsi Aceh
Abstrak: Pengangguran adalah salah satu penghambat pembangunan ekonomi di Indonesia. Aceh merupakan provinsi yang memiliki angka pengangguran tertinggi pada tahun 2013 dengan nilai 10.3 persen. Hal tersebut disebabkan kurangnya perhatian pemerintah terhadap pembangunan sektoral yang berperan tinggi dalam menyerap tenaga kerja. Penelitian ini bertujuan untuk menganalisis leading sector terhadap penyerapan tenaga kerja serta faktor-faktor apa saja yang memengaruhi penyerapan tenaga kerja di Provinsi Aceh. Penelitian ini menggunakan 2 metode yaitu metode analisis input-output dan metode Ordinary Least Square (OLS). Hasil penelitian menunjukkan bahwa sektor kehutanan merupakan leading sector terhadap penyerapan tenaga kerja di Provinsi Aceh. Namun, jika dilihat dari sisi output, pendapatan, dan tenaga kerja sektor yang menjadi leading sector adalah sektor industri pengolahan. Oleh karena itu, pemerintah Provinsi Aceh sebaiknya mengembangkan sektor industri pengolahan yang menggunakan output sektor kehutanan sebagai input pada sektor tersebut. Variabel yang berpengaruh positif signifikan adalah pertumbuhan PDRB, investasi dalam negeri, dan jumlah angkatan kerja. Sedangkan upah minimum provinsi dan investasi asing berpengaruh negatif signifikan terhadap penyerapan tenaga kerja.

Judul: Analisis Keterkaitan Antar Sektor Ekonomi di Provinsi Aceh : Pendekatan Input-Output
Abstrak: The economic sectors have a crucial role in the development of both national and regional economy. A comprehensive and sustainable economic integration among all production sectors is the key to a successful economic development. In a market economy, an integrated economy can be seen when interaction occur among the economic players-buying and selling the input and output of production. The objectives of this research were to (1) analyze the contribution of economic sectors in the development of Aceh province, (2) analyze the linkage among the economic sectors in the development of Aceh province, (3) analyze the impact (multiplier) of changes in the final demand on output, income and labor in the economic sectors, and (4) analyze the impact of changes in the consumption expenditure of the household, government, and export on output, income and labor economic sectors. Input-output tables were used to analyze the magnitude of linkages among the sectors in the economic development of a region. The results showed that the gas mining sector in the economic sector with a relatively large role in the creation of output and added values in the economic development of Aceh province. In terms of the linkage level, the sector with the greatest value of direct backward linkage is the electricity sector, while the sector with the largest value of direct and indirect backward linkages are the industrial sectors of food, beverages and tobacco. Meanwhile, the sector with the biggest value of forward linkage is the trade sector, whereas the gas mining sector has the biggest value of direct and indirect forward linkage. Based on the output multiplier value, the output of food, beverages and tobacco industrial sectors have a relativey large value compared with the other economic sectors. As for the value of income multiplier, electricity sectors as well as industrial sectors of food, beverages and tobacco have relatively high multiplier values. In terms of the labor multiplier, the sector with a relatively high multiplier value is the milling industry of rice, grain and flour. Meanwhile, result simulation the scenario of first showed that increasing the number of output whole the economic sector has a relatively large compared with increase of income and labor. The result simulation the scenario of second showed that decrease consumption of the household and government there caused to decrease the number of output and labor in whole economic sector. While result simulation the scenario of third showed that if the export was raised, increasing the number of output is relatively larger than increase of income and labor. Of the three of simulations to increase the number of output be the third scenario is capable to producing the greatest number of output in whole economic sector.

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.
