Abstract

North African catfish (Clarias gariepinus) is a food ingredient with high protein content, so it is needed as a source of nutrition. In intensive catfish farming activities, there are constraints on water quality. The high stocking density causes a high value of ammonia. In addition, Nitrobacter, in an intensive aquaculture system, is expected to improve water quality. Especially ammonia, so that it can increase the growth and survival of fish. This study aims to determine the effect of Nitrobacter with different doses on the maintenance of North African catfish. This research was conducted from September to October 2022 at the Aquaculture Environmental Quality Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Universitas Riau, Pekanbaru. The research method used in this study was a completely randomized design (CRD) 1 factor with five treatment levels and three replications. The treatment in this research is P0: Dosage Nitrobacter 0 mL/L, P1: Dosage Nitrobacter 0.5 mL/L, P2: 1 mL/L, P3: 1.5 mL/L, and P4: 2 mL/L. Giving Nitrobacter is done once a week according to the dose of each treatment. This research was conducted for 30 days. The research results show that dosing Nitrobacter has different effects on reducing ammonia levels and maintaining North African catfish. The best treatment was P3 1.5 mL/L with the smallest ammonia content of 0.0403 mg/L. a specific growth rate of 0.98%. An absolute growth rate of 0.76 g, an absolute length of 1.06 cm, and a survival rate of 81.4%. The value of water quality during the research was 29-300C, pH 6.5-7.0, and DO 2.9-3.3 mg/L.

Abstract

The existence of coral reef ecosystems in Indonesia is a potential marine resource that needs to be preserved due to the many benefits of the coral reef ecosystem. Utilization of Sentinel-2A imagery for coral reef mapping can be done using two approaches, namely pixel-based and object-based. In this study, pixel-based classification and object-based classification are used to determine the dynamics of the distribution of coral reefs in the waters of Pejarakan Village, Bali, during the dry and rainy seasons. The data used are Sentinel-2A image data for 2018, 2020, and 2022 and field data used for the research accuracy test process. Field data was collected using the purposive sampling method, and the accuracy test process was carried out using the confusion matrix method. The data processing results using pixel and object classification show that classification using the object classification method is considered more accurate than pixel classification because it produces an accuracy value of up to 69.4%. Meanwhile, the pixel classification accuracy value is only 61.1%.

Abstract

Oil pollution in the waters is one factor affecting the abundance of phytoplankton, especially the diatoms. The waters of Bengkalis Strait, Pangkalan Jambi Village, and Bengkalis Regency are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundant of planktonic diatoms, and explain the relationships between the total oil content and the abundant of planktonic diatoms carried out in the Bengkalis Strait, Pangkalan Jambi Village Bengkalis Regency, Riau Province. This research uses a survey method. Station 1 is near fish ponds and mangroves, station 2 is in the harbor where the fishing boats moor, station 3 is in wharf bridge and residential areas, and station 4 is in mangrove ecotourism. The result of the oil content analysis obtained an average value of 0.216 ppm. The highest oil content at station 2 is 0.5742 ppm, and the lowest at station 4 is 0.0775 ppm. The calculations of the abundance of planktonic diatoms ranged from 3,323.28 to 11,631.48 ind/L. The highest abundance at station 3 was 9,692.2 ind/L. The lowest abundance was at Station 2, which was 4,154.1 ind/L. Simple linear regression test results obtained equation Y = 6045.927572 + (3013.071268x). The coefficient of determination (R2)= 0.049 states that 4.9% of the abundance of planktonic diatoms is influenced by oil content, and other environmental factors influence the rest. The correlation coefficient (r) = 0.0223, so the relationship between total oil content and the abundance of planktonic diatoms is very weak

Abstract

Research on tidal analysis based on seasons has been carried out in Lasolo Bay, Southeast Sulawesi, using secondary data, namely tidal data in 2021 in January representing the western season, April representing the transition season I, July representing the eastern season and October representing the transition season II. This study aims to determine the type of tides formed and the value of sea level elevation in each season at the research site. Tidal data processing uses the admiralty method, producing amplitudes and phase differences from 9 main harmonic components. The analysis results of the calculation of formzhal numbers show that the type of tides formed in Lasolo Bay is a mixed type of double daily inclined with a formzhal number value of 0.5618-0.7059. In addition, based on the calculation of sea level elevation, the maximum average sea level (MSL) occurs in the second transition season (October), which is 532 cm, and the western season (January) is 460 cm. For the other two seasons, the first transitional season (April) and the eastern season (July) have an average sea level of 101 cm and 130 cm

Abstract

AFIS 1.0 is a helpful communication tool for sending and receiving automatically operated Morse lamp signal news. In this study, researchers developed AFIS 1.0 because there were still some shortcomings in the previous device, namely that AFIS 1.0 was still operated using a PC, could not store its power, could not be portable, and was not equipped with recorded data. This study aims to identify the attributes of AFIS 1.0, redesign the prototype AFIS 1.0 according to the attributes obtained and test the results of the prototype AFIS 2.0. The method used in this study is ethnography, where the researcher directly observes respondents in the field. Kansei engineering is used to translate respondents' psychological feelings and needs into product design parameters. The results of this study are in the form of a prototype AFIS 2.0 with the Android operating system, equipped with a rechargeable battery, can be installed permanently and portable, equipped with data recording, Morse complex and the tool can be operated automatically or manually. In testing the results of the prototype AFIS 2.0 conducted by the Head of KRI SIM-366 and the Head of KRI Nala-363, it was stated that the tool can be appropriately operated so that AFIS 2.0 can answer respondents' wishes in the field. With the development of AFIS 2.0, it is hoped that communication with soldiers on KRI will be more straightforward in sending and receiving news of Morse lamp signals
