Abstract

Dumai City as an autonomous region has a strategic location with potential natural resources. With these conditions in the city of Dumai developing economic activities such as industrial estates, aquaculture, fisheries, transportation, tourism and other activities. On the other hand Dumai City also has a stretch of mangrove along the coast which is feared to experience problems due to these activities. This study aims to determine the economic value of mangrove ecosystems in Dumai City. The study, conducted in March 2019. The method used in this study is a survey method. The determination of sampling points was done by purposive sampling in 4 (four) stations: Station I (Bangsal Aceh), Station II (Muara Sungai Masjid Area), Station III (Muara Sungai Dumai), and Station IV (Tanjung Palas) Dumai City, Riau Province . The method used to estimate the economic value of resources is the Total Economic Value (TEV). WTP analysis with the Contingent Valuation Method (CVM) is likened to an approach to measure how much willing to pay. Direct use value such as the use of mangrove wood, mullet fish, shrimp, and mangrove crabs is Rp. 97,258,416,000.00 and indirect use values measured from the value of the construction of breakwaters and mangroves as nursery ground in the amount of Rp. 4,616,250,000.00. The choice of value measured from the amount of mangrove utilization as a recreation area is Rp. 1,836,000,000.00. The value of the existence and inheritance value calculated from the community's willingness to pay WTP (Willingnes To Pay) of Rp. 670,080,000.00 and Rp. 233,360,000.00, and non-use value of Rp. 893,440,000.00. So that the total economic value of mangrove forests in the coastal area of Dumai City per year is Rp. 104,604,106,000.00.

Abstract

A clean and healthy lifestyle (CHL) is a health behavior which comes from one’s own awareness sothat a family member or a family could help him/herself with his/her health problems. To apply theCHL among the family or family members, the Health Department of Republic of Indonesia hascreated a health promoting program and has been decided as a flagship program. However, thenational health survey (2010) indicated that CHL nationally was still far from the minimal target(65%) of the year. The same thing goes to the implementation of the CHL in Sekijang Sub-district,Pelalawan Regency. Pelalawan Regency Health Profile shows that of 2010 households monitored,only 38% had had CHL inclusion. The present research seeks to investigate the correlation betweenthe community empowerment strategies and the individual CHL increase of families among theplantation community within the working area of Seikijang Community Health Center, PelalawanRegency. The data were calculated using Univariat and Bivariat analysis of Chi-Square. The resultsshow that there is a significant correlation between the community empowerment strategies and theindividual CHL increase in Seikijang Sub-district. The strategies shows that there is a significantcorrelation between advocacy and individual CHL, p value 0.007 < 0.005. then, there is a significantcorrelation between the community empowerment and the individual CHL increase, p-value 0.001 <0.05. There is a significant correlation between the atmosphere management and the CHL increase, pvalue 0.000 < 0.05 in Seikijang Sub-district. It is suggested that all parties be more proactive in theCHL program. The success of the program would have a positive impact on all parties, either on theHealth Office, the Community Health Center or on the community and each individual in a family.
