Abstract

Serewe Bay is an important area for sustainable fisheries. This information on benthic habitats is important to know for sustainable management. However, at the moment there is no information on the distribution of benthic habitats in Serewe Bay. The research utilizes Sentinel 2A satellite imagery where the image used is obtained through the earthexplorer.usgs.gov website. Image data will be analyzed through several correction analysis processes, namely reflectance correction, sunglint, and water column or Lyzenga in order to obtain an image display that can be used to identify benthic habitats in Serewe Bay. In addition, a field data survey was also carried out to test the accuracy of the results of processing the Sentinel 2A satellite image of Serewe Bay. Image processing results show that there are 3 categories of benthic habitats, namely Seagrass, Sand and Mixed habitats in which there are macroalgae, dead coral, and coral fractures. The results of the field survey and accuracy calculations show that the accuracy of sentinel 2A image processing in Serewe Bay reaches 63.41% with the dominant benthic distribution consisting of seagrass, mixed benthic habitat and sand. Meanwhile, the calculation of the area of important benthic habitats such as seagrass beds in Serewe Bay can reach 156 Ha.
PENGARUH PENAMBAHAN JUMLAH BERAT BATU ZEOLIT YANG BERBEDA PADA TRANSPORTASI BENIH IKAN NILA (OREOCHROMIS NILOTICUS): The Effect Of Additioning Different Amount Of Weight Of Zeolite Stones On Transportation Of Tila Fish Seeds (Oreochromis niloticus) Muhammad Akbar; Aryani Rahmawati; L.A.T.T.W.

Abstract

This research aims to determine the effect of adding different weights of zeolite stone on the survival rate of tilapia (Oreocrhomis niloticus) seeds during the transportation process carried out at BBI Batu Kumbung, Lingsar District, West Lombok Regency. The method used in this research is an experimental method. The data analysis used was Analytical Analysis (ANASRA) at a real level of 5% and 1% to determine the percentage of mortality of the object under study. The results of this research were the use of zeolite stones with different weights for transporting tilapia (Oreocrhomis niloticus) seeds. The results of observations in treatment X0 using zeolite stone weighing 10 g mean percentage of life 74.66%, X1 treatment uses zeolite stone weighing 20 grams with an average survival percentage of 77.33%, X2 treatment uses zeolite stone weighing 30 g with an average survival percentage of 82.66%, and treatment X3 using zeolite stone weighing 40 g with an average survival percentage of 88.66%. ased on the Variety Scan analysis, it shows where F Calculated < F Table 5%, so it can be concluded that H0 is accepted or H1 is rejected, meaning that the difference in the weight of the zeolite stone does not have a significant effect on the survival rate of tilapia (Oreochromis Niloticus)

Abstract

The purpose of this study was to determine the Construction and operational techniques of the Bubu (fish trap) fishing gear, to determine the best types of bait in fishing activities and to determine the number and types of fish caught using the Bubu (fish trap) fishing gear. This study used an experimental method with the experimental design used was a Completely Randomized Design (CRD), then continued with the Least Significant Difference (LSD) test at 5% and 1% levels, to determine the smallest difference from each treatment. While the factors observed in this study were 3 (three) different types of bait, namely bait A: Anchovy, bait B: Lemuru Fish and bait C: Stingray. The results of the study showed that the trap given bait A (anchovy) got the most catch, which was 11.9 kg, then the second order was bait B (lemuru fish) with a catch of 7.7 kg, and the least catch was bait C (stingray). The water quality observed during the study included: water clarity ranging from 6.10 - 8.90 m, current speed ranging from 10 - 15 cm, salinity ranging from 27 - 29 ppt, temperature ranging from 29 - 30oC, the depth of the research location waters averaged 12.5 m and the sandy bottom of the waters was slightly coral. There were significant or very significant differences between each research treatment. The 5% BNT test showed a result of 0.38, meaning that X1 and X2 showed significantly different results, X1 and X3 showed significantly different results and X2 and X3 showed significantly different results
