Abstract

Danau Panjang is a natural lake located in Lubuk Siam Village. The variety of activities in Danau Panjang can affect phytoplankton biodiversity. Phytoplankton is an important factor for the life of fish and all kinds of biota that live in water as primary producers. The presence of phytoplankton will determine the quality and condition of a body of water. Danau Panjang, as one of the oxbow lakes, currently rarely has any additional discharge from the main river, so it is feared that phytoplankton diversity will be low. This study aims to determine the type and abundance of phytoplankton and phytoplankton biodiversity and the results of the analysis of environmental factors on phytoplankton biodiversity in Danau Panjang. Phytoplankton biodiversity and water quality parameters consisting of temperature, brightness, depth, pH, CO2, DO, nitrate, and phosphate were observed in September-October 2023. Phytoplankton samples and water quality measurements were taken at three sampling points, three times with an interval of two weeks. Phytoplankton abundance ranged from 2383-7098 cells/L, and 10 phytoplankton classes were found. Phytoplankton biodiversity in Danau Panjang illustrates a relatively stable condition. The species richness index in Weeks 1, 2, and 3 ranged from 3.51-5.52 in the good category. The diversity index in Weeks 1, 2, and 3 ranged from 2.06-3.82, with a high level of diversity. The dominance index in Weeks 1, 2, and 3 ranged from 0.12-0.38, indicating that there was no dominant species. The uniformity index in Weeks 1, 2, and 3 ranged from 0.39-0.69, where uniformity was in balance. In general, the water quality in Weeks 1, 2, and 3 is not much different and is favorable for phytoplankton growth when viewed from the quality standards of class III of PP No. 22 of 2021.

Abstract

Artificial Lake is one of the lakes located in Lembah Sari Village, Rumbai Pesisir District, which was expanded into East Rumbai District on December 30, 2020, with an area of ​​166.40 ha. The various activities in the artificial lake cause a decrease in water quality due to the input of waste dumped into the lake, thus impacting the ecological condition of the biota, one of which is macrozoobenthos. This research aims to determine the environmental status of bottom waters using macrozoobenthos. This research was carried out in July-August 2023 at three stations. The abundance of macrozoobenthos ranges from 115-465 ind/m3, with the species consisting of 2 classes (Gastropoda and Oligochaeta) divided into four families. Generally, the macrozoobenthos found are the Oligochaeta, tolerant class, and the Gastropoda, facultative class. The diversity index for Stations I, II, and III ranges from 1.010 to 1.224, with a medium level of diversity. The ecological quality of the waters in the Artificial Lake based on the ABC Curve method for Stations I, II, and III showed that the seas were lightly polluted. In general, the water quality at Stations I, II, and III is not much different, where the parameters of temperature, brightness, depth, TSS, pH, and DO are still by class II quality standards PP No. 22 of 2021, but the BOD content is high. High BOD values ​​indicate the amount of organic material at each station.

Abstract

Fisheries resource management based on local wisdom is passed down through generations, addressing significant challenges like over-exploitation. Teluk Paman Timur Village exemplifies this with its ‘Lubuk Larangan’ model, where specific river areas are designated for fishing prohibition, enforced by the community. This research examines the environmental conditions of water's physical-chemical parameters, the economic and social benefits of ‘Lubuk Larangan,’ and the current fisheries management status in the village. Using qualitative descriptive methods, data was gathered through observations, interviews, and water quality measurements. Results indicate that the ‘lubuk larangan’ system in Teluk Paman Timur is actively maintained. Management falls under the auspices of Ninik Mamak, POKMASWAS, and BPD, benefiting from community support. Economically, ‘Lubuk Larangan’ meets local consumption needs while providing additional income opportunities. Socially, it facilitates gatherings, cooperation, and activities during harvest seasons. Water conditions within ‘Lubuk Larangan’ are favorable, as evidenced by quality parameters like dissolved oxygen, temperature, pH, clarity, current speed, depth, and TDS, which comply with class 2 water quality standards vital for sustaining fishery resources and aquatic life. This governance model, therefore, enhances both ecological health and community resilience, ensuring sustainable fisheries management

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
