Abstract

Ibu rumah tangga merupakan potensi tersendiri untuk pengembangan ekonomi dan nutrisi keluarga. Ikan lele dumbo memiliki rasa gurih dan telah menjadi bagian dari menu masyarakat Riau. Di sisi lain, ikan ini relatif mudah dibudidayakan, tahan terhadap lingkungan ekstrim bahkan di daerah sempit tanpa perlu air mengalir. Kegiatan ini bertujuan membina ibu rumah tangga untuk memelihara ikan lele dumbo di dalam drum, membuat pakan ikan lele sendiri dan memproses sebagian dari hasil panen mereka. Program ini diadakan di Kampung Minas Barat, Kabupaten Siak, Riau dengan menggunakan metode demonstrasi langsung. Para peserta diajari cara membuat pakan ikan, budidaya ikan lele dan kegiatan pasca panen. Dimulai dari pembentukan kelompok dan pengangkatan ketua dan sekretaris. Dilanjutkan dengan kegiatan tatap muka, praktik langsung membuat pakan ikan, persiapan wadah tumbuh, penebaran benih ikan dan pemeliharaan. Setiap peserta diberikan 1 unit drum bervolume 200 L, 300 ekor bibit ikan dan sejumlah pakan ikan lele yang mereka produksi sendiri. Satu unit mesin pembuat pelet diserahkan kepada kelompok ini. Kegiatan pemantauan dilakukan terus menerus dengan setiap 2-3 minggu, baik melalui kunjungan langsung atau melalui telepon. Peserta binaan terlihat serius, antusias dan rajin dalam menjalankan program ini. Sampai di akhir kegiatan ikan sudah mulai dipanen dan dikonsumsi oleh anggota keluarga sendiri. Dilihat dari perspektif penguatan ekonomi keluarga dan peningkatan gizi rumah tangga, kegiatan ini dianggap cukup baik dan diharapkan ditiru oleh anggota masyarakat lainnya.

Abstract

Lokan (Polymesoda expansa) is a bivalve in mangrove forest areas with important ecological and economic values. The lokan population plays a role in maintaining water quality and is a source of livelihood for coastal communities. This study aims to analyze the abundance, distribution patterns, and frequency distribution of individual sizes of P. expansa in the mangrove forest of Banglas Village, Meranti Islands Regency. The research was conducted in December 2024 using a survey method to determine station locations by purposive sampling. Sampling was conducted at three stations, each consisting of three transects with plots measuring 1 × 1 m². The results showed that the highest abundance was found at Station III (±16.33 ± 5,508 ind/m²) and the lowest at Station II (8.33 ± 2,082 ind/m²). The distribution pattern of lokan at all stations is clustered (Morisita index value> 1). The frequency distribution of individual sizes showed the dominance of sizes 3.40-3.89 cm with 21 individuals. Abundance and distribution patterns of lokan are influenced by habitat conditions, human activities, and food availability. ANOVA test results showed no significant differences in abundance between stations, but there were significant differences between subzones. Knowledge of the population structure of P. expansa is vital for sustainable resource management in mangrove ecosystems

Abstract

Sungai Selari Village is an area in Riau Province that features a high density of water activities, including a port where many fishing boats are moored and also serves as a transportation route for fishermen seeking fish. This activity can cause water pollution, which leads to the silting of waters through sedimentation. The activity of sediment input into a body of water can cause changes in the ecosystem, including alterations in sediment texture, organic matter content, and the abundance of macrozoobenthos biota. One organism that can be affected by differences in ecosystems is the macrozoobenthos due to its sedentary nature. This study aims to determine the type of sediment, grain size, and organic matter content, as well as their relationship with macrozoobenthos abundance. This research was conducted in March and April 2023, utilizing purposive sampling techniques at four stations in total. The samples taken were sedimentary substrates and macrozoobenthos. The results indicated that the size of the dominating sediment stalk, specifically the mud fraction, ranged from 14.72% to 71.25%. The types of macrozoobenthos found are grouped into two classes, namely Gastropods and bivalves. Individual abundances range from 0.3 - 4.4 ind/m2, with the highest abundance occurring at station 4 and the lowest occurring at station 1. The organic matter content ranges from 9.27- 34.2%. The relationship between organic matter content and macrozoobenthos abundance exhibits a moderate correlation of 0.506. The relationship between sediment grain size and macrozoobenthos abundance shows a fairly close correlation of 0.544

Abstract

Macrobenthos is a community of organisms that spend part or all of their life cycle on the bottom of the waters, either crawling, sessile, or digging holes. This study aims to analyze the structure of the macrobenthos community in the intertidal zone of Marapalam Beach, South Coast Regency, West Sumatra Province. Sampling was carried out at three stations. Station I (mangrove), Station II (tourist spot), and Station III (fishing boat). Macrobenthos sampling used the purposive sampling method. Macrobenthos sampling at the bottom of the waters using a shovel, the substrate was filtered using a 1 mm2 mesh size sieve to separate the organism samples from the substrate. The results showed that the macrobenthos found on Marapalam Beach consisted of 2 classes and five families, five genera, and nine species of macrobenthos. The highest abundance of macrobenthos was found in the species Clypeomorus batillariaeformis. Diversity of research locations (H' 1.19), Dominance (C 0.17), Diversity (E 0.87), Clustered distribution patterns (Id 5.51), and similarity indexes of 71-100% are categorized as high species similarity

Abstract

Coral reefs are massive piles of sediment from calcium carbonate produced by the phylum cnidaria, class Anthozoa, and order Madreporaria, with the addition of calcareous algae and other organisms that produce calcium carbonate. One group of biota that lives in association with coral reefs and plays a vital role in the coral reef ecosystem is the Chaetodontidae fish. The taking of the Chaetodontidae family as research material is because the coral fish of the Chaetodontidae family are indicator fish for coral reef health that can assess, monitor and predict the condition of coral reefs. Given the importance of the function and the existence of coral reefs. This study aimed to determine the condition of coral reef cover, analyze the abundance of reef fish in the Chaetodotidae family, and determine the relationship between coral reef cover and the abundance of reef fish in the Chaetodotidae family. This study was conducted in December 2024 in Sikuai Island, West Sumatra. This study used survey methods, such as UVC (underwater visual census) and UPT (underwater photo transect). The research location was divided into three stations in the southern part of Sikuai Island because the southern part is relatively protected from large waves during the west wind season. Station I is next to Sirandah Island, Station II is in the harbour area, and Station III is in the abandoned ship area. The analysis showed that the highest percentage of coral cover was found at Station III, namely 45.13%, and the lowest rate was found at Station I, 6.47%. The calculation of reef fish abundance showed that the highest abundance of reef fish was found at station III, namely 5000 ind / ha and the abundance of reef fish at station I was 6.47%.
