This study aimed to analyze the distribution of phytoplankton abundance and its relationship with water quality in Lasolo Bay waters. The study was conducted during the West Season 2020. The sample consisted of 9 stations located near the mouth of the Lasolo River (station A), coastal waters (Station B) and the center part of Lasolo Bay (Station C). Phytoplankton sampling was using plankton nets with 25 µm meshsize. Identification of phytoplankton used microscope and the abundance calculation by using Sedgwick Rafter Counting Cell. The results showed that there are 23 phytoplankton genera from 5 classes found, namely 12 genera of Bacillariophycea Class, 5 genera of Dinophyceae Class, 3 genera of Chlorophyceae Class, 2 genera of Cyanophyceae class and 1 genera of Coscinodiscophyceae class. By abundance, phytoplankton compositions of the class Bacillariophyceae predominate with a percentage of 57%. The type of phytoplankton that has the highest abundance is Nitzschia sp. of 2,407 cells/l and the lowest abundance of Amphidium sp. of 1,368 cells/l. Phytoplankton abundance at Station A is 41,093 cells/l, station B is 14,234 cells/l and station C is 14,735 cells/l. The distribution of phytoplankton abundance is also influenced by physical and chemical factors such as turbidity, TSS, Nitrate and Phosphate.
The village of Tanjung Tiram is a coastal area with considerable fishery resource potential. Community services activity through Program of student study service and community empowerment (KKN-PPM) program for 45 days from May 20<sup>th</sup>–July 16<sup>th</sup> 2017. The activity aims to provide knowledge and empower the community of Tanjung Tiram Village through the enhancement of value added potential of aquatic resources (seaweed and fish). The activity was conducted through training to make various processed food products based on seaweed and fish so that economic value of fishery products increases. In addition there are also alternative jobs for fishermen/communities who have been doing the utilization of natural resources that damage (no eco-friendly). The result that had been obtained in this activity was the community understand the method of processing and packaging of processed seaweed and fish products, and they have succeeded in making processed products in packaging that is ready to be marketed.
Kondisi perikanan demersal di perairan Taman Nasional Wakatobi (TNW) pada zona pemanfaatan khususnya di Karang Kapota bisa dinyatakan padat tangkap, sehingga perlu dilakukan suatu penelitian mengenai perencanaan dan pengembangan perikanan demersal melalui pendekatan sistem untuk mengurai permasalahan yang terjadi. Penelitian ini bertujuan untuk mengidentifikasi karakteristik perikanan demersal, menganalisis stakeholders yang terlibat, dan mendesain sistem pengelolaan perikanan demersal di Karang Kapota TNW. Penelitian dilaksanakan dari bulan Juni sampai September 2019 di Karang Kapota TNW. Pengambilan data primer dilakukan dengan metode purposif di sentra-sentra perikanan demersal sedangkan data sekunder diambil dari instansi terkait. Data primer dan sekunder dianalisis dan disajikan dalam bentuk tabel, gambar, dan dijelaskan secara deskriptif. Data-data yang akan ditampilkan adalah karakteristik perikanan demersal, analisis stakeholders, dan analisis sistem perikanan demersal. Karakteristik perikanan demersal menunjukan bahwa hasil tangkapan yang dominan adalah ikan lencam (27%) dengan armada penangkapan terbanyak digunakan yaitu bodi batang (62,5%). Pemangku kepentingan yang terlibat yaitu nelayan dan DISPAR berada pada kelompok dengan kepentingan tinggi tetapi pengaruhnya rendah (subjects); DKP Kabupaten, BTNW, RARE, TNC, PSKP, Komanangi, Kelompok Padang Kauwang sama, Koordinator/Pengumpul Lokal, Bappeda, UD. Pulau Mas, dan LPSTK Wakatobi berada pada kelompok dengan kepentingan dan pengaruh yang tinggi (players); dan DKP Provinsi dengan kepentingan dan pengaruh yang rendah (by standers). Diagram sistem pengelolaan perikanan demersal yaitu alat tangkap harus ramah lingkungan, meningkatkan armada pengawasan, mempertegas aturan hukum, serta adanya keterlibatan masyarakat dan nelayan dalam pengelolaan perikanan demersal
