SUSTAINABILITY ANALYSIS OF WHITELEG SHRIMP POND AQUACULTURE AT JATIRENGGO VILLAGE, LAMONGAN REGENCY

Whiteleg shrimp (Litopenaeus vannamei) is a fisheries commodity which has high economic value because of its high demand and easier cultivation. Lamongan regency is one of the minapolitan region in East Java Province, especially at Glagah district, Jatirenggo village which becomes the minapolist, with one of the superior commodities is whiteleg shrimp. The development of a certain village can be determined by village developing index or IDM which consists of three categories, they are left behind, developing, and advance village. Jatirenggo village has a village developing index (IDM) of 0.6080 which classified as developing category or category 2. Thus, in order to increase its status, the welfare of its people need to be considered. Whiteleg shrimp pond aquaculture can be one of the effort to increase the income of Jatirenggo’s. This study aims to analyze the sustainability of whiteleg shrimp aquaculture activity in Jatirenggo village according to ecology, socio-economic, technology-infrastructure, and institutional dimension. The used method was MDS Rapfish. The results showed that the whiteleg shrimp aquaculture in Jatirenggo village is classified as sustainable, or it means the situation in Jatirenggo village is suitable for a successful aquaculture. Thus, it can be expected to increase the income of the farmers.


INTRODUCTION
Lamongan regency is one of the minapolitan region in East Java Province, especially at Glagah district which becomes the core sector or minapolist, with one of the superior commodities is whiteleg shrimp.In this region, the production of whiteleg shrimp is always increasing by average

RESEARCH METHODS
The research is part of the community service at Jatirenggo village, Lamongan regency, East Java Classification of sustainability status is presented in Table 1.

RESULT AND DISCUSSIONS
The result of goodness-of-fit calculation for MDS-Rapfish analysis is displayed in Table 2. Since the criteria for goodnessof-fit is fulfill, then the analysis to assess sustainability status for each dimension.

Figure 1 Sustainability Index for Ecology Dimension
Source: Add-ins Ms. Excel Rapfish, 2018 Figure 1 shows that the sustainability status for ecology dimension is 78.18 or classified as sustain.Thus, the ecological state in Jatirenggo village is very supporting the Whiteleg shrimp pond aquaculture.

Figure 2 Attributes Sensitivity for Ecology Dimension
Based on Figure 2, shrimp disease issue, water and soil quality for cultivation need to be considered since its leverage for sensitivity is the highest.

Socio-Economic Dimension
The sustainability index and attributes sensitivity are presented in Figure 3 and 4.

Technology and Infrastructure Dimension
As for the sustainability index and attributes sensitivity for technology and infrastructure dimension are displayed in Figure 5 and 6.Sustainability Analysis …… (Evellin Dewi Lusiana 1 , Muhammad Musa 2 , Mohammad Mahmudi 3 , Sulastri Arsad 4 , Nanik Retno Buwono 5 ) Whiteleg shrimp (Litopenaeus vannamei) or also known as Pacific White Shrimp is an introduced species which has high economics value because of its high demand.This species got into Indonesia in 2001 and started to be cultivated in aquaculture pond at Banyuwangi and Situbondo region, along with the decreasing production of tiger shrimp as the consequence of White Spot Syndrome Virus (Sugama, 2002).The advantages of whiteleg shrimp are its high growth rate, resist to disease, and has high tolerance to the environmental change(Widodo & Dian, Sustainability Analysis …… (Evellin Dewi Lusiana 1 , Muhammad Musa 2 , Mohammad Mahmudi 3 , Sulastri Arsad 4 , Nanik Retno Buwono 5 ) Jurnal Ekonomi Pembangunan Volume 16 No. 2 Desember 2018 94 2005).Beside, Briggs et al. (2004) also stated that its stock density is relatively high up to 150 heads/m 2 , wide range salinity tolerance (0.5-45 ppt), low protein needs (20%-30%) and better food conversion ratio (1.2<FCR<1.6).
