Abstract

The global market demand for vaname shrimp in Indonesia is increasing every year. Vannamei shrimp is a mainstay of fisheries commodities. Cultivators often encounter vibriosis disease caused by Vibrio sp. Therefore, it is necessary to pay attention to the quality of the feed by adding supplements from synbiotics and empon-empon. This study aims to determine the effect of synbiotics and empon-empon on the growth of white shrimp (Litopenaeus vannamei) larvae in controlling Vibrio sp. Parameters measured included daily length growth, survival, water quality, total bacteria, and total vibrio. Water quality and total bacteria are growth-supporting factors. The treatments consisted of positive control (C+), negative control (C-), Synbiotic 1 (S1), Synbiotic 2 (S2), Synbiotic 3 (S3), Synbiotic 4 (S4), and empon-empon (E). The synbiotics used were Bacillus sp 1x 1010. as a probiotic, 2 ppm yam paste as a prebiotic and 1 ppm  ginger, 1 ppm white turmeric, and 1 ppm black cumin. And the combination of the three types of empon-empon with a concentration of 0.5 ppm (treatment S4 and E). The results showed that the S2 treatment had a significant effect (P>0.05) on the daily length of the fry with an average of 0.05±0.06 mm. The S4 treatment had a significant effect on survival with a percentage of 83.6%. The lowest total Vibrio was shown in the S4 treatment with a value of 0.45±0.5 logs CFU/ml. The total density of bacteria was shown in the S2.treatment with a value of 2.28 ±log CFU/ml.

Abstract

Budidaya ikan di keramba jaring apung idealnya dilakukan sesuai dengan prinsip ekonomi biru sambil tetap menjaga kelestarian ekosistem. Tujuan penelitian ini untuk sejauh mana prinsip ekonomi biru diterapkan dan penjagaan kelestarian ekosistem pada budidaya ikan KJA di Kecamatan Teluk Pandan, Kabupaten Pesawaran, Provinsi Lampung pada bulan Juli – September 2024. Data dikumpulkan dengan cara wawancara mendalam, observasi dan studi pustaka, selanjutnya dianalisis untuk mengukur sejauh mana prinsip tersebut diterapkan. Hasil penelitian menunjukkan bahwa sebagian besar pembudidaya ikan tidak mengenal istilah "ekonomi biru". Namun beberapa prinsip ekonomi biru, seperti memajukan pertumbuhan ekonomi, memperbaiki kesejahteraan sosial dan menjaga ekosistem laut, telah diimplementasikan meski belum sepenuhnya optimal. Contohnya adalah upaya pembudidaya dalam tidak membuang sampah sembarangan dan menggunakan pakan sesuai padat tebar optimal. Diperlukan bimbingan teknis yang intensif untuk memperkuat penerapan prinsip ekonomi biru pada usaha budidaya ikan dengan sistem KJA.

Abstract

Steam power plant is a power plant that uses steam energy as the main turbine engine to produce electricity. Most steam power plant are built in coastal areas because it requires water for its utilization as waste heat or coolant from the surrounding environment. The construction of steam power plant in coastal areas has caused several issues, such as hot water waste, coal waste, mud, sand, and others that can affect the quality of coastal waters and alter the biological composition in the ocean. The purpose of this research is to determine the impact of Steam Power Plant X wastewater disposal on the phytoplankton community structure and coastal water quality in South Lampung. The sampling points were taken at 3 stations in March-April 2024. Water samples were analyzed using 3 parameters: physics, chemistry and biology, with seven optional parameters measured both ex situ and in situ, namely pH, temperature, salinity, brightness, TSS, nitrate and plankton. Based on the results, the disposal of wastewater from Steam Power Plant X has an impact on the phytoplankton community structure, resulting an increase in dominance of phytoplankton species and causing an increase in physical parameters such as temperature and brightness that exceed environmental quality standards.
