Judul: Analisis Dayasaing dan Faktor-faktor yang Memengaruhi Aliran Ekspor Pala Indonesia
Abstrak: Development of export demand for Indonesia nutmeg on international market can be identified by the rate of its export volume. The objective of this study was to analyzing comparative and competitive advantage of indonesia nutmeg in six export destination countries, there are Netherland, Belgium, Germany, Italy, USA and Singapore and what the factor influences the export volume of Indonesia nutmeg. RCA method showed that comparative advantage held by indonesia nutmeg on the whole export destination countries (RCA>1). The result of Export Product Dynamic (EPD) showed that the Indonesia nutmeg has a high competitive advantage on Netherland, Italy, USA and Germany market and at the same time share of export has decreased on Belgium and Singapore market. There is twoway trade on Netherland, Singapore, Belgium and Italy. This result can be determined by analyzed using Intra-Industry Trade method (IIT). The estimation result of Gravity Model showed that real economic distance and real prices of world’s nutmeg influences export volume of indonesia nutmeg.

Judul: Competitiveness and Affecting Factors of Indonesian Nutmeg Export
Abstrak: The agricultural sector is a sector that makes a huge contribution to the GNP. Nutmeg is one of Indonesia's plantation export commodities that has high economic value. Indonesia's nutmeg export value during the period 2010-2019 quite volatile and there are still several obstacles that cause Indonesia’s nutmeg experienced rejection in destination countries. The objectives of this study are: 1) analyze the competitiveness of Indonesian nutmeg exports; 2) analyze the factors affecting Indonesian nutmeg exports. This study uses RCA, EPD, TII and Diamond's Porter method to determine the competitiveness of nutmeg, and uses a Gravity Model to determine the factors that affect Indonesian nutmeg exports. The RCA's results shows that Indonesian nutmeg has a higher comparative advantage in the six destination countries. The EPD's results are the Rising Star of the United Arab Emirates, the Falling Star of Vietnam and Germany, the Lost Opportunity of China and the Retreat of the United States. TII shows that Indonesia has intense trade relations with China, Vietnam, the Netherlands and the United States. In Diamond Porter's analysis, the supporting industry factors have not been optimal in supporting the competitiveness of Indonesia’s nutmeg exports, while other factors tend to be positive in supporting the competitiveness of Indonesia’s nutmeg. The Gravity Model's results shows that all independent variables have a significant impact on the export value of nutmeg.

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.
