Abstract

Betta (Betta sp.) is an anabantidae fish with sexual development that can be directed at the embryonic and larval stages. One way to direct the sex development of these fish is by using hormone therapy using natural ingredients. Coconut water is one of the natural ingredients that can be used because it contains high potassium. This potassium can convert cholesterol in fish body tissue to pregnenolone which will affect the increase in testosterone production. This study aims to determine the best dose and age group in directing the sex of Betta fish experimentally using a randomized block design (RBD) with 4 treatments and 3 replications. The immersion treatment of larvae in the age group of 3 days, 5 days, and 7 days for 15 hours with a dose of 0%, 10%, 20%, and 30% coconut water was carried out in a 3 L jar containing 30 larvae. The results showed that coconut water was able to influence the increase in the percentage of male betta fish (P <0.05) with the highest value at a dose of 30% as much as 86.26 ± 8.34% and the 3 day larvae age group of 72.78 ± 16.03, and have a different effect on other treatments. In addition, the survival calculated after immersion shows a value of 100%, meaning that coconut water does not have a harmful effect on fish. Based on the results of this study, the best treatment for directing the sex of betta fish is a dose of 30% coconut water with the 3 day age group.

Abstract

This research was conducted in March 2020 at BPBALP Teluk Buo, West Sumatera. This research aimed to determine the best dose for urea usage on S. costatum cell growth. The method used in this research was an experimental method using Completely Randomized Design (CRD) with one factor, which was the various doses of urea fertilizer consisting of five treatments with three replications. Urea various doses used were 0 ppm (control treatment), 40 ppm (treatment A), 60 ppm (treatment B), 80 ppm (treatment C), and 100 ppm (treatment D) totaling 15 treatment units. The tested organism in this research was S. costatum. The container used was a plastic jar with 2 liters capacity. The parameters tested in this research were the maximum cell population density achieved by seven days of maintenance, absolute growth rate, relative growth rate, and specific growth rate. The results showed that the best cell density was found at the treatment D (100 ppm), which was 1,228 x 104 cells / mL and the lowest cell density was in the control treatment (without urea) which was 533 x 104 cells / ml. The results of water quality measurements during the study were still in an adequate range and met the maintenance requirements of S. costatum. The range of water quality parameters were salinity 26-28 ppt, temperature of 25-27oC, and pH of 8.

Abstract

This research was conducted in February 2021 at the mouth of the Dumai River, Rupat Strait. The purpose of this study was to determine the effect of sediment supply from land on changes in bathymetry in the waters of the Rupat Strait based on the analysis of suspended sediment (SSC) and suspended solids (TSS) divided by the area of the study. The method used is a survey method. The results showed that as much as 26,94 tons/year of sediment entered the Rupat Strait and was distributed in the research area. Each part of the research area has a different bathymetric change value. This is presumably due to oceanographic factors in the waters of the Rupat Strait such as strong and weak river currents when entering the sea, the distance between the research area and the sediment supply source, human activities in each part of the study area, erosion along the river and abrasion at the river mouth. the presence of mangrove forests, dominant sediment types, sloping water topography, the cross-sectional width of the river as a sediment supplier, and suspended solids.

Abstract

Bawean Island is one of the islands in Gresik Regency, East Java, where almost all its territory is a coastal environment. This region's tidal oceanographic condition is critical because this area has a lot of potential for marine tourism and relatively shallow waters. This study aims to determine the tidal characteristics in the waters of Bawean Island, East Java, using the Admiralty method. This method was chosen because it can calculate the tidal component with only 15 days of data and can be used in various water conditions. The data used is tidal data from the Geospatial Information Agency (BIG) on November 1-15, 2020. From this research, it can be concluded that tidal analysis using the Admiralty method produces nine components, including M2, S2, N2, K1, O1, P1, M4, MS4, and K2. The four components determine the type of tide, namely O1, K1, M2, and S2, with amplitude values of 11.79347, 30.14857, 55.72241, and 63.69851. The calculation with the Formzahl number equation yields a value of 0.3512 (0.25 <F <1.5), which means that the tidal type in Bawean Island, East Java, has a mixed type with a semidiurnal tendency (double daily).
