This study aims to analyze the influence of the tourism sector on economic growth in East Nusa Tenggara during the period 2015 - 2018. The data used is data from 20 districts/cities in NTT. The approach method used is descriptive analysis and panel data. Based on the results of the analysis of the variable, number of tourist visits, the number of hotels, the number of restaurants and the number of tourist attractions as well as the local income and labor force variables have a positive and significant influence on economic growth in East Nusa Tenggara. The tourist attraction variable is the tourism variable that has the highest influence on economic growth. This can be a concern for the government to encourage the tourism sector to become a potential sector in encouraging economic growth in the province of East Nusa Tenggara.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
