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.

Abstract

This study aims to determine the effect of feeding containing fermented chicken feather flour on feed efficiency and growth of striped catfish fry. The test fish used weighted 2.85 ± 0.33 g. The containers used for observing fish growth were 15 units of floating net cages made of gauze measuring 1x1x1 m with a stocking density of 25 ind/m3 and 5 units of aquariums measuring 60x35x40 cm as containers for observing the digestibility of feed with a stocking density of 25 ind/m3. This research method used a one-factor Completely Randomized Design (CRD) with five treatment levels and three replications. The treatments in this study were P0 (feed without fermented feather meal), P1 (feed containing 7.5% fermented feather meal), P2 (feed containing 15% fermented feather meal), P3 (feed containing 22.5% flour fermented chicken feathers), and P4 (feed containing 30% fermented chicken feather flour). The test feed protein was about 40%. The amount of feed given is 5% of the body weight of the fish with a frequency of 3 times a day, namely morning, afternoon, and evening. Fish rearing was carried out for 56 days. Measure the digestibility of feed by giving feed containing an indicator of 0.5% chromium oxide (Cr2O3). Feed is offered three times a day, namely morning, afternoon, and evening, as much as 5% of the body weight of the fish. The feces excreted by the fish are then collected and dried. The collected feces were analyzed for protein content and Cr2O3 to obtain feed and protein digestibility data. The results of this study indicated that the best treatment was P3 (feed containing 22.5% fermented chicken feather meal), resulting in feed digestibility of 55.36%, protein digestibility of 85.39%, feed efficiency of 83.59%, protein retention of 36.33%, specific growth rate of 3.38%, and survival of 92.00%.

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. The value of water quality during the study was good enough to support the survival of North African catfish.

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.
