Abstract
The purpose of this study analyze the impact of Covid-19 on input factors and output factors on the pattern of utilization of capture fisheries. This research was conducted in 2020 in Cirebon Regency. The methodology used quantitative descriptive. The results of the analysis indicate, first, the impact of COVID-19 on input parameters has not changed, such as fishing fleets, trips, fishing ground, crew members, and operational costs. Some changes only occur in certain commodities. For example, in crab fishermen, they adjust their fishing gear on commodities sold for the domestic market. Previously, they used traps to catch crabs. Since the Covid 19 pandemic, they have used rampus to catch small pelagic fish. Second, in TCT commodities, the variables that change are mainly the output parameters, namely production volume, price, and revenue. The impact of covid 19 was felt during March-May 2020, which was when the PSPB was implemented. There was a decrease in production in 2020 compared to the previous year. It is hoped that the government will increase its cold storage capacity, so that if there is a lockdown in the export destination country, the output from fishermen can be temporarily accommodated in cold storage.

Abstract
Fighting fish Betta dennisyongi is a popular ornamental freshwater fish in Indonesia. Male fighting fish are preferred because the colour pattern and shape of the fins are more attractive so they are more expensive. This study aims to determine the optimum temperature of rearing media water on the male sex ratio and survival rate of fighting fish larvae. A completely randomized design method with three replications was used in this study. The tested rearing temperature water was: 26°C, 28°C, 30°C, and 32°C. Fish were kept for 40 days. The results of the ANOVA test showed that larval rearing temperature affected significantly the ratio of male and female fish larvae survival (P<0.05). The highest percentage of the male sex was found at a temperature of 32 °C (93.33%), this value was significantly different from other temperature treatments. Meanwhile, the highest larval survival was obtained at a rearing temperature of 28 °C (80.00%), where this value was significantly different from other treatments. Therefore, with economic considerations, it is concluded that the optimal larval rearing media temperature is 28 °C.

AbstractEcoport management is a port management trend around the world. Unfortunately, Indonesia has not implemented it properly and the focus is only on the performance of ship services and loading and unloading services. Tanjung Intan Seaport as a port that continues to grow, has it implemented ecoport management? Is the performance of the ship’s service and loading and unloading optimal? This research objective area: (1) knowing and analyzing the management of ecoport at Tanjung Intan Seaport. (2) knowing and analyzing the performance of ship services at the Tanjung Intan Seaport; (3) knowing and analyzing the performance of loading and unloading services at the Tanjung Intan Seaport. The results show that Tanjung Intan Seaport has not consistently implemented ecoport management. Likewise, the performance of ship services and loading and unloading services has not been entirely good. Ship services, namely approach time 1.26 hours, delay time for domestic vessels 22.7 hours, postpone time for foreign vessels 8.19 hours, turn round time for domestic vessels 138.52 hours, all of them are good, as well as loading and unloading services for ET:BT domestic vessels 84 % already well. However, loading and unloading services are not good for ET:BT for foreign vessels 54.78%, T/S/D for domestic vessels 6.567 tons, T/S/D for foreign vessels 5.725 tons, because they are under the CBWP (2021) standard as well as the national standard.

Abstract

Colossoma macropomum is freshwater fish which has a great demand in Indonesia. However, cultivation of C. macropomum is still developing. C. macropomum cultivation requires a good quality seeds to support the success of aquaculture. The exhausted egg yolks of C. macopomum larvae require appropriate and high-nutrient feed intake through enrichment of feed with the addition of natural feed nutrients (Moina sp.). This study aimed to evaluate the effect of additional Moina sp. enriched with fish meal on the survival and growth of C. macropomum. This study was structured using a completely randomized design (CRD) consisting of 4 treatments with 3 replications, namely: treatment A (Moina sp. without enriched with fish meal), treatment B (Moina sp. enriched with fish meal 4 gr/L), treatment C (Moina sp. enriched with fish meal 6 gr/L), and treatment D (Moina sp. enriched with 8 gr/L fish meal). The results showed that the additional of Moina sp. enriched with fish meal had a significant effect on the absolute length growth, absolute weight growth, and specific growth rate but had no significant effect on survival of C. macropomum. The highest value was obtained in treatment C (Moina sp. enriched with fish meal 6 gr/L) with the absolute length growth of 0.46 cm, absolute weight growth of 0.010 gr, and specific growth rate of 3.184%/day.
