Golden sea cucumber or locally known as “teripang emas” is one of Indonesia’s most popular sea cucumber and widely processed as functional food or supplement due to its bioactivities. The sea cucumber is often misidentified due to its morphological similarities with other Stichopus spp. This study aimed to identify the golden sea cucumber obtained from West Nusa Tenggara, Indonesia, by a molecular method and study the antioxidant activities of its collagen hydrolysates. The hydrolysates were produced by hydrolyzing acid collagen extract using neutrase for 30, 60, 120, 180, and 240 mins. The products were then analyzed for their degree of hydrolysis, peptide content, molecular weight distribution and radical scavenging activity by the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. Results showed that hydrolysis for 180 mins was optimal in producing the highest peptide content, 12.79 ± 0.44 mg/mL, with a degree of hydrolysis (DH) of 55.2 ± 1.50%. However, the highest antioxidant activity (IC50 of 5.25 ± 0.15 mg/mL) was demonstrated after 60 mins hydrolysis with molecular weight (MW) ranged from less than 14.4 kDa to approximately 25 kDa. The hydrolysate might be categorized as a weak to moderate antioxidant. Based on the molecular identification, the golden sea cucumber had 99% similarities with Stichopus horrens and S. monotuberculatus.
ABSTRAKPetani tambak membudidayakan bandeng dengan menggunakan sistem tradisional dan sistem semi intensif, padahal perbedaan sistem yang digunakan akan menimbulkan perbedaan penerimaan petani. Selain itu tingkat pendapatan dan produktivitas pada usaha mereka juga akan berbeda. Tujuan penelitian ini adalah untuk mengetahui perbandingan tingkat produktivitas tambak bandeng pada sistem tradisional dan sistem semi intensif di Labuhan Kuris, Kecamatan Lape, Kabupaten Sumbawa -NTB. Teknik pengambilan sampel menggunakan Metode Purposive Sampling dan Metode Analisis Data yang digunakan adalah Mann-Whitney U-Test. Hasil pembahasan uji rata-rata data produktivitas tambak ikan bandeng sistem tradisional dan sistem semi intensif diperoleh nilai p < 0.05, artinya terdapat perbedaan signifikan antara data produktivitas, dimana produktivitas sistem semi intensif lebih tinggi dibandingkan sistem tradisional. Artinya terdapat perbedaan signifikan antara data pendapatan, dimana pendapatan sistem semi intensif lebih tinggi dibandingkan sistem tradisional. ABSTRACTMany pond farmers cultivate milkfish by using traditional and semi-intensive system, whereas the difference of system used will generate the difference of farmer's revenue. The aim of this research is to know the comparison of milkfish pond's productivity level by traditional and semi-intensive system in Labuhan Kuris, Lape subdistrict. Sampling technique applies Purpose Sampling method and data analysis method be used is Mann-Whimey U-test. The result of average test of milkfish pond's productivity data within traditional and semi-intensive system gets p value < 0.05 means that there is significant difference between productivity data, where intensive system productivity is higher than traditional system. means that there is significant difference between yields data, where the yields of intensive system is greater than traditional system. PENDAHULUANLuas wilayah Kabupaten Sumbawa yang dilihat dari peta wilayah adalah 10.475,7 km² meliputi luas daratan 6.643,98 km² dan luas perairan laut 3.831,72 km² dengan panjang pantai ± 982 km dan luas perairan laut yang termasuk Zona Ekonomi Eksklusif (ZEE) 74.000 km².

Social entrepreneurship as base on technology transfer is a real contribution of shrimp farming company in Sumbawa district province of west Nusa tenggara a company under the auspices ( LSO ) limp shrimp organization in the conduct of it is business supported by human resources such as engineer, architect, manager, doctor, and most of professional aquaculture in the world which aims to open up jobs and to increased income of local society, since of 2000 LSO always to consistently apply high technology from china in company management, these company whom introduces white shrimp fasific to asia such as ( Indonesia, Filipina, china ) Morever LSO has other ability covers urban planning desaign, technic, aquaculture, management, operate, infrastructure, logistic, cold chain, value added marketing. By promote the principle of success to achieve sustainable success, this is to address inequality identical income to become a frequent problem which is often faced by an area. Income inequality tends to be highly and extremely if not immediately overcome will cause unrest in society such as higher crime rates, the gap is getting worse between the rich and poor, and handling and repair which increasingly difficult with inequality which tends to be extreme. So as to minimize the impact of income inequality must know what factors influence income inequality, the presence of the company below in LSO with the concept of social entrepreneurship is part of the answer the social phenomenon.Keywords:Social Entrepreneurship as a Real Contribution to the Sumbawa Shrimp Farming Company
