Ecotourism management of North Mareje Mountain Forest Area (NMMFA) is one of ways to achieved sustainable development goals (SDGs) in Central Lombok District. The lack of ecotourism economics value information causes investment for its development runs relative slowly. This study aims to valuate and evaluate the economics value of ecotourism development in NMMFA. The data used in this study includes number of tourist visits during 2018-2019, tourists visit frequency, travel costs and their socio-economic characteristics. Data was collected by interviewing NMMFA’s managers and tourists using questionnaire. Economic valuation analysis was carried out by using the traveling cost method (TCM). Economic evaluation diagnosed using paired t-test by comparing observed versus potential economic values. The Analysis result shows that the willingness to pay (WTP) of tourists whom visit to NMMFA=IDR. 347.579/visit with economic value = IDR 3,72 B/year. The economic evaluation results explains that the observed economic value = IDR. 986,78 M/year is smaller than the potential economic value of it carrying capacity ones =IDR 127,05 B/year. To improve economic development, it required a new paradigm of forest management by making current conservation activities become a conservation business and improving sustainable ecotourism management aspects.

The increase pressure on marine capture fisheries due to rising demand for seafood, growing population, and a rapid increase in fisheries exploitation, brought about a decline in productivity of many fisheries.Last issues of ocean degradation were related to; overfishing, pollution, habitat destruction (coral reef). FAO (2008) reported that 32% of fish stocks are ove-rexploitated, depleted or recovering from depletion, and this figure is rising every year.This unsustainability of marine and coastal ecosystem were related to overfishing, pollution and waste, habitat destruction (coral reef), climate change, and loss of habitat and biodiversity. Aware of those issues and threats the productive and valuable ocean area lies at risk. Therefore, a concept of Ecosystem Based-Management (EBM) was introduced. The approach lays out a series of principles to guide management toward long-term sustainability of marine and coastal management. Further beyond the sustainability,the term “blue economy” has been used by the Pacific Small Island Developing States Perspective (PSIDS). in effort to highlight the importance of conservation and sustainable use of marine resources.

Anadara granosa is one of the bivalves that are often found in public markets. This study aimed to study the relationship between length-weight and sex ratio of blood clams (A. granosa) in the coastal waters of West Rangsang. Sampling was carried out every month at three stations. Shells were collected from a 1 x 1 m2 plot on a quadratic transect. The relationship between length and weight was analyzed by regression analysis. The sex ratio between the number of female and male blood clams in each month of sampling was calculated and followed by the Chi square test to test the similarity. The results showed that the relationship between length and weight of A. granosa was positive allometric. The sex ratio of female and male blood clams in the waters of West Rangsang is not balanced. The number of male blood clams is more than the female.
