Abstract

This research was conducted from February to March 2023 in Setan island, West Sumatra. This study aimed to determine the sediment accumulation rate and coral cover, as well as the correlation between sediment accumulation rate and coral cover. The survey method was used in this research. The sediment accumulation rate was measured using a sediment trap. At the same time, the coral cover was observed using the underwater photo transect (UPT) method with a transect length of 50 m. The total suspended solid was analyzed using the Gravimetric method. Observations were made at four sampling points at depths of 3 and 6 m. The sediment accumulation rate at a depth of 3 m ranged from 0.946315 to 1.534992 mg/cm²/day, while at a depth of 6 meters, it ranged from 1.357756 to 1.607786 mg/cm²/day. The percentage of live coral cover at a depth of 3 meters ranged from 3.40% to 31.36%, and at a depth of 6 m, it ranged from 0.33% to 30.50%. The total suspended solids values ranged from 23 to 96 mg/L. Regression analysis showed that the sediment accumulation rate negatively influenced the percentage of live coral cover.

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

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.

Abstract

Chlorella sp is a kind of phytoplankton used as a natural food source for zooplankton, such as fish larvae and shrimp. Chlorella sp contains various nutrients that are good for the growth of fish larvae and shrimp. The success in cultivating Chlorella sp is closely related to the nutrient content at the time of cultivation. One alternative cultivation of Chlorella sp is using bean sprout extract and coconut water as the medium. Bean sprouts and coconut water extract can be used as a substitute for inorganic fertilizers. This research aims to determine the effect of bean sprout extract and coconut water on the growth of the density of Chlorella sp, as well as grasping the best dose that can be used to cultivate Chlorella sp. This research was conducted in July 2022 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This research used a one-factor, Completely Randomized Design (CRD) with four treatments and three replications. The treatments as defined in this research were P0 (Walne fertilizer 1 mL/L as control), P1 (8% bean sprout extract + 10% coconut water), P2 (10% bean sprout extract + 12.5% coconut water) and P3 (bean sprout extract 12% + coconut water 15%). These results indicate that P3 (12% bean sprout extract + 15% coconut water) is the best treatment for the growth of Chlorella sp with a density of 1091.00 x104 cells/mL and a specific growth rate of 0.9607 sel/mL, which occurred on the sixth day.

Abstract

This research was conducted in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province on November 21 - December 09, 2022, to analyze the profit-sharing system for drift gill net fishermen and compare the profit-sharing system that applies in Bagan Hulu Village with the Law No.16 of 1964 concerning profit sharing. The method used was a survey with a total sample of 32 fisherman owners; the sampling technique was simple random sampling. The results showed that the profit-sharing system for drift gill net fishermen in Bagan Hulu Village, Bangko District, Rokan Hilir Regency, Riau Province, uses a local profit-sharing system by sharing profits after deducting production costs with a percentage of 60% for fisherman owners and 40% for labor fishermen provided that all operational costs are shared. From a comparison of the profit-sharing system according to UUBHP, the share of income for fishermen who own drift gill nets in Bagan Hulu Village is greater than that according to UUBHP. The difference can be seen from the joint costs incurred. In the law, the shared costs incurred are consumption, while in the Bagan Hulu Village, the shared costs incurred are all operational costs.
