TOURISM LEAKAGE OF THE ACCOMMODATION SECTOR IN BALI

Tourism has been a driving force of economic development and has become the leading economic sector in Bali Province. However, the economic impacts of tourism development have not been fully beneficial for the Balinese community. Tourists' expenditure has not been totally remaining in Bali's economy. Some of the expenditures by tourists leak out of the destination, called tourism leakage, in the form of payments for imported products and services, payment of wages for foreign employees, and profits transferred to foreign owners. So far, the amount of tourism leakage in Bali has not been calculated. Therefore, there is a need to ascertain the current amount of leakage in Bali tourism. This paper estimates the amount of tourism leakage from the accommodation sector in Bali through a micro analysis at the industrial level. There were 79 hotels selected as a sample based upon a purposive probability to size sampling method in four main tourist destinations in Bali, namely Kuta, Nusa Dua, Sanur and Ubud. Four types of accommodation were considered in estimating tourism leakage. The results showed that the highest percentage of leakage was in the 4 & 5 Star-rated chain hotels, i.e. 51.0 % of total revenue. It was followed by the 4 & 5 Star-rated non-chain hotels (22.7 %), and 1, 2 & 3 Star-rated hotels (12.0 %). Meanwhile, the lowest leakage was on the Non star-rated hotels (8.8 %). Overall, the average tourism leakage on accommodation sector in Bali was 18.8 %. These results indicate that (i) the higher the level of hotel classifications, the more leakage will be; and (ii) accommodation which was owned by a foreigner and/or managed by an international chain had more leakage than other types of accommodation. The more leakage, therefore the less revenue from tourism will be directly received by hotel and undirectly by the local community as tourism is the main source of economic development of Bali Province

The Potential of grxB Gene for Detection of C. sakazakii in Infant Formula Milk Using Real-Time Polymerase Chain Reaction

Cronobacter sakazakii is one of the bacteria that causes food poisoning that contaminates infant formula. This pathogen causes necrotizing enterocolitis, sepsis, and meningitis in infants or neonates with reported case fatality rates ranging from 40% to 80%. Therefore, it is necessary to develop fast and accurate detection of C. sakazakii in infant formula milk. This research aims to develop a method for detecting C. sakazakii bacteria using real-time PCR with high sensitivity, specificity, and accuracy. A rapid detection method using real-time PCR with the target gene grxB successfully detects the presence of C. sakazakii DNA in artificially contaminated formula milk. The results of the real-time PCR test showed that C. sakazakii DNA with a concentration of 53 ng/µL could be amplified by the grxB gene primer pair with a Ct value of 12 and a Tm value of 85.8ºC. The specificity test showed that the grxB primer could differentiate between target and some non-target bacteria. The sensitivity test showed the ability of the grxB primer to detect the smallest concentration of 3,392 pg/µL with a Ct of 24,06. Based on the results obtained, it can be concluded that the grxB primer has the potential to be used as rapid detection method for C. sakazakii bacteria in infant formula using real-time PCR
