Abstract

Fish feed is critical to the success of aquaculture as it fulfills nutritional needs, promotes growth, and improves fish health. Several feed forms are used routinely, such as flake, pellet, and cake, each with its characteristics and applications, depending on the fish species and growth stage. Flake feed is a good choice for ornamental fish and small fish that consume on the surface or in the water column because it allows it to float longer on the water surface, making it easier for small fish to consume. Cake-shaped feed is soft, denser, and has a distinctive cake aroma. Cake-shaped feed is usually used for larval-stage fish species with small mouth openings. In addition, pelleted feed, available in various sizes and densities, is becoming more popular in consumer fish farming because it is easy to apply and can meet balanced nutritional needs, especially for sizeable juvenile fish. Pellets can be adjusted to match the water density for fish feeding at the water's top, column, or bottom. Therefore, it is crucial to know the forms of feed and their uses so that farmers can choose the optimal feed for their fish by understanding the characteristics and applications of each type of feed.

Abstract

This research aims to determine the use of rice straw as a packaging medium for the survival, growth, induction, and sedation of lobster seeds transported for 6, 9, and 12 hours using the Completely Randomized Design (CRD) method. The research preparation includes preparing the maintenance medium, filling medium, and test animals (adaptation for 7 days after arrival and fasting for 24 hours). The main research involves acclimating lobster seeds using temperature manipulation for approximately 5 minutes, with transport media temperatures ranging from 10º to 12º, and then maintaining them for 28 days. The research results indicate survival, growth, induction, and sedation time differences. The fastest induction time occurred in the treatment with a 9-hour transport duration, lasting 4.14 minutes. The fastest sedation time occurred in the 6-hour transport duration, lasting 1.56 minutes. Post-transport survival is highest after 6 hours and 9 hours of treatment, which is 95%. The best post-maintenance survival is found after 6 hours of transportation, at 91%, while the treatments at 9 and 12 hours yield 86% and 76% results, respectively. This research indicates that straw can be utilized as a filling medium for up to 12 hours

Abstract

Funding for fishermen's enterprises refers to the costs fishermen require to procure investment goods and operational costs for fishing activities. Funding for fishermen's enterprises is sourced from various channels. This research was conducted in May 2024 in Kuala Indragiri District, Indragiri Hilir Regency, Riau Province. The research has two objectives: first, to describe the procedures for funding fishermen's enterprises. The second objective is to determine the influence of funding procedures and the socio-economic conditions of fishermen on the decision to borrow from non-formal sources. The sample consisted of 79 fishermen from 3 villages selected using the purposive sampling. Data collection was done through interviews, documentation, and questionnaires. Data analysis was conducted using Descriptive Analysis and Multiple Linear Regression. The results of the descriptive analysis show that the procedures for funding fishermen's enterprises can be sourced from self-funding, family, and non-formal sources referred to as "container", with a value of 3.94 categorized as easy. The multiple linear regression analysis results yielded the equation Ŷ = 17.465 + 0.477X1 - 0.306X2. The research results indicate that funding procedures positively and significantly impact the decision to borrow from non-formal sources. Meanwhile, socio-economic conditions negatively and significantly affect the decision to borrow from non-formal sources. There is a positive and significant simultaneous influence between funding procedures and socio-economic conditions on borrowing from non-formal sources. The variable model can predict borrowing decisions from non-formal sources by 52.2%, with 47.8% influenced by other variables

Abstract

The Air Bangis fish landing base is the only fish landing base in Sungai Beremas District, Pasan Barat Regency, and is classified as a type D fishing port. The imbalance between dense fishing activities and limited available facilities results in suboptimal fishing activities. This research was conducted using a survey method in May-June 2024 at the UPTD Regional II Air Bangis Fishing Port, West Sumatra Province. Data analysis used facility needs analysis and facility utilization level analysis. The facilities available at the Air Bangis Fish Landing Base consist of basic, functional, and supporting facilities. Of the 17 existing facilities, four whose utilization levels were analyzed were facilities that significantly influenced capture fisheries activities and were considered suboptimal in supporting dense fishing activities, namely land, docks, depth and area of ​​port ponds, and TPI. The level of facility utilization obtained a value ranging from 17 to 61%, consisting of 2 facilities that have a level of utilization exceeding the capacity of the available facilities so that they are included in the category of not optimal, namely the dock and harbor pool. In contrast, the TPI's utilization level does not exceed the available capacity; facilities that are not used are the ice factory, cold storage, and fuel tanks.

Abstract

Aquaponics is a sustainable aquaculture technology that integrates a recirculation aquaculture system with plant cultivation in one system. The aquaponic system can be a solution that can be used as an intensive fish farming system and increase fish farming production. However, intensive cultivation will cause dissolved oxygen concentration to decrease rapidly. It will affect the water's quality, so an aeration system is needed to maintain the balance of dissolved oxygen in the water. The difference in the use of aeration systems in aquaponic systems will certainly provide different water quality results. So, this study aims to determine the type of aeration system most effective for cultivation activities in the aquaponic system. The method used in this study is a descriptive exploration of various literature and research results that have been published, both from books, national journals, and international journals. Based on a comparison of the results of previous studies, it can be concluded that aeration technology with microbubble sizes such as MNB and FBs can increase oxygen higher and more stable than conventional and venturi aeration technologies. The application of MNB and FBs aeration technology can produce water quality with dissolved oxygen concentration >7 mg/L, reduce ammonia concentration to <0.01 mg/L, nitrate concentration to <0.6 mg/L, and phosphate concentration <0.3 mg/L, as well as reducing total solids to 16% and volatile solids to 32%.

Abstract

This study was conducted in January 2023 at the Bungus Ocean Fishing Port to determine the achievements of operational performance and problems faced by operational activities and to what extent the Bungus PPS has implemented the level of operational performance of the Bungus Ocean Fishing Port over the past five years. The survey method was used in this study. The evaluation of operational performance at PPS Bungus is based on Kep-DJPT no 20/KEP-DJPT/2015, which contains four parameters and 28 sub-parameters. The results showed that operational performance's success value had run very well from 2017 to 2021, with values ranging from 86.75 to 89. However, several subparameters have low values: fisheries production, fishery product processing services at WKOPP, port land use (according to the master plan), and labor absorption. The value of fishermen's satisfaction with PPS Bungus' operational services in 2023 is 91.76%, which means it is perfect.
