Published: February 2022

Phytoplankton is one of the important components in aquatic ecosystems. This organism plays an important role as a primary producer to support the life of the tropics above it. The purposesÃÂ of this study were to reveal the abundance and diversity of phytoplankton species in the waters of Sekotong Bay, West Lombok. Sampling were conducted in July 2018 at 8 stations using plankton net and then observed at the Laboratory. The results of the abundance calculations show a varied pattern at each observation station. The highest abundance was found at station 8 (9,060 ind/L) followed by station 6 (8,300 ind/L), station 7 (6,490 ind/L), station 4 (4,440 ind/L), station 3 (3,980 ind/L) , station 5 (2,820 ind/L), station 2 (2,460 ind/L) and station 1 (2,440 ind/L). The Shannon - Wiener Species diversity Index also shows diverse patterns at each station. Station 7 has the highest diversity index value (HÃ¢â¬Â² = 3.55), followed by station 6 (HÃ¢â¬Â² = 3.46), station 8 (HÃ¢â¬Â² = 3.18), station 1 (HÃ¢â¬Â² = 2.72) , station 2 (HÃ¢â¬Â² = 2.69), station 5 (HÃ¢â¬Â² = 2.67), station 4 (HÃ¢â¬Â² = 2.33) and station 3 (HÃ¢â¬Â² = 2.26). Species dominance index at all stations at low category with the highest dominance found at station 3 (D = 0.19), followed by station 4 (D = 0.18), station 2 (D = 0.09), station 5 (D = 0, 09), station 1 (D = 0.08), station 8 (D = 0.06), station 6 (D = 0.05) and station 7 (D = 0.04). Species Evennes index (E) values ranged from 0.71 to 0.88, indicating that the number of individual species wasÃÂ relatively the same and the ecosystem was in relatively good condition. The analysis showedÃÂ that the spatial pattern of abundance and diversity of phytoplankton species in Sekotong Bay was related to the distance from the estuary.

Intensifikasi budidaya ikan gurame pada UKM (Kelompok Pembudidaya Carper) mitra Program Kemitraan Masyarakat (PKM) sangat dibutuhkan untuk memenuhi permintaan benih yang semakin besar. Intensifikasi ini dilakukan dengan mengingtegrasikan system budidaya resirkulasi dan penggunaan pakan formulasi komersial. Penerapan sistem budidaya resirkulasi diterapkan karena pembudidaya memiliki lahan dan air terbatas terutama di musim kemarau sedangkan pemanfaatan pakan formulasi pada induk dan benih dilakukan untuk mendukung dan mempercepat pematangan gonad, proses pemijahan, produksi benih dan pembesaran benih. Kegiatan ini bertujuan untuk meningkatkan produksi dan menghasilkan benih berkualitas sehingga meningkatkan pendapatan UKM Mitra. Kegiatan ini dilaksanakan di Desa Margacinta, Kab. Konawe Selatan, Prov. Sulawesi Tenggara. Produksi dan budidaya massal benih dilakukan menggunakan bak fiber ukuran 1 ton dan diterapkan system pendederan bertahap dan setiap tahap dilakukan seleksi untuk memperoleh ukuran benih standar . Kegiatan percontohan intensifikasi budidaya gurame pada PKM ini, telah menunjukkan hasil produksi dan budidaya massal benih gurame dengan pertumbuhan dan sintasan yang dihasilkan tinggi pada setiap tahap pendederan serta memberikan keuntungan yang sangat memuaskan bagi Mitra PKM. Kegiatan PKM ini telah memberikan manfaat dan hasil yang sangat memuaskan yaitu mempermudah manajemen produksi benih; mulai dari pengontrolan, pemberian pakan dan panen; meningkatkan produksi benih dan pendapatan, mempermudah manajemen pemesaran benih dan mengatasi masalah kekurangan air pada musim kemarau sehingga produksi benih berkelanjutan sepanjang tahun.

Published: February 2022

Evaluating the presence of fresh water snails in a location is germane in establishing a snail-borne disease control program. The purpose of the study was to see how physicochemical parameters influenced the population distribution of four fresh water snails (Lymnaea natalensis, Bulinus globosus, Biomphalaria pfeiffer, and Melanoides spp.) in the Amassoma community and Niger Delta University between March, 2021 and May 2021. Snails were gathered by plucking and scooping them by hand. Snail was identified using standard pictorial keys. Physicochemical of the water of the snail habitat were measured using standard in-situ apparatus across eight sites. Physico chemical measured were temperature, pH, conductivity, BOD, turbidity, salinity, and alkalinity. A total of 258 snails were gathered from the eight (8) different sites. In all sites, Lymnaea natalensis was more abundant. Bulinus globosus, Biomphalaria pfeiffer, and Melanoides spp. were among the other snails discovered. Lymnaea had negative correlation with pH, conductivity, BOD, and alkalinity and a positive correlation with salinity and temperature. Bulinus had a positive relationship with pH, salinity, and conductivity and a negative correlation with temperature, turbidity, BOD, and alkalinity. Biomphalaria had a positive correlation with temperature, pH, salinity, turbidity, and alkalinity Melanoides had positive correlations with Temperature, pH, salinity, BOD, and alkalinity and a negative correlation with turbidity and concentration. The was correlation between snails and snails. The presence of these snails suggests that the Amassoma village and Niger Delta University campuses are potential hotspots for a variety of snail-borne diseases.
