Seaweeds of the genus Gracilaria are an important aquaculture commodity, commonly cultured in brackish water ponds as well as in coastal waters. In South Sulawesi, Indonesia, the Gracilaria acultured in ponds has been named G. verrucosa, while Gracilaria cultured in coastal waters has been named G. gigas. Morphologically, these two types of Gracilaria do look different. Detailed examination shows that they appear to have similarities. This study aimed to examine whether these two types of Gracilaria are different species or not. The study used morphological characters and COI mitochondrial gene barcoding to assess the Gracilaria types cultured in ponds and coastal waters. Samples were collected from Ujung Baji Village in Takalar Regency, the main seaweed producing region in South Sulawesi Province, Indonesia. The results indicate that both Gracilaria types have similar genetic characteristics as well as shared morphological characters. Based on these analyses, it is considered that both Gracilaria types cultivated may be strains of the same species.

ABSTRAKIkan terbang merupakan salah satu sumberdaya perikanan yang melimpah dan memiliki nilai sosial ekonomi cukup penting karena salah satunya dijadikan sebagai usaha pengasapan ikan di Provinsi Sulawesi Barat. Program Kemitraan Masyarakat Melalui Penerapan Teknologi Pengasapan Ikan Terbang Di Kelurahan Mosso, Kabupaten Majene, Provinsi Sulawesi Barat, bertujuan untuk meningkatkan kemampuan dan keterampilan masyarakat tentang cara produksi ikan asap yang baik. Kegiatan ini dilaksanakan pada bulan Juni 2020 di Kelurahan Mosso, Kecamatan Sendana, Kabupaten Majene, Provinsi Sulawesi Barat. Mitra kelompok yang menjadi sasaran utama pengabdian ini yaitu kelompok usaha pengasapan ikan terbang “Siamasei Lestari”. Metode yang digunakan pada kegiatan pengabdian ini Penyuluhan dan praktek cara produksi ikan asap yang baik serta introduksi teknologi alat pengasapan ikan. Hasil yang dicapai dari kegiatan ini antara lain meningkatnya kemampuan dan keterampilan masyarakat tentang cara produksi ikan asap yang baik dan adanya alat pengasapan ikan yang dapat digunakan untuk pengembangan usaha mitra program kemitraan masyarakat. Beberapa keuntungan dari penggunaan alat pengasapan ikan antara lain efisiensi penggunaan asap sehingga produk cepat matang, kualitas yang seragam dan warna yang lebih menarik, kuantitas produk lebih banyak, produk akhir yang lebih higienis, menghemat biaya produksi karena efisiensi bahan bakar yang digunakan optimal dan produk akhir yang lebih higienis karena proses produksi tidak terkontaminasi.   Kata kunci: Ikan terbang; pengasapan; program kemitraan masyarakat; sulawesi barat; teknologi ABSTRACTFlying fish is one of the abundant fisheries resources and has quite important socio-economic value because one of them is used as a fish smoking business in West Sulawesi Province. The community development program through the Application of Flying Fish Smoking Technology in Mosso Village, Majene Regency, West Sulawesi Province, the aims to improve the capacity and skills of the community on good smoked fish production methods. This activity was carried out in June 2020 in Mosso Village, Sendana District, Majene Regency, West Sulawesi Province. The group partner who is the main target of this service is the flying fish smoking business group "Siamasei Lestari". The method used in this service activity provides counseling and practice of good smoked fish production methods as well as the introduction of smoking equipment technology. The results that were achieved from this activity included the improvement of the community's abilities and skills on how to produce smoked fish properly and the existence of a fish smoker that can be used for business development of community partnership program partners. Some of the advantages of using fish smoking equipment include the efficient use of smoke so that the product ripens quickly, uniform quality and more attractive color, more product quantity, more hygienic final products, saving production costs due to optimal fuel efficiency and final product. which is more hygienic because the production process is not contaminated. Keywords: flying fish; smoked;  community development program; west sulawesi;  technology

The reduction in the quantity of mangrove forest ecosystems will certainly have a negative impact on the balance of coastal ecosystems, people who live in coastal areas, and of course sustainable sustainable development proclaimed by the local government. The research objective is to analyze the damage of mangrove forest ecosystems through Environmental Science approach. One approach to the study in question is the remote sensing approach. The study was conducted throughout August 2018 precisely at Mampie Beach, Wonomulyo Subdistrict, Polewali Mandar District. The collection of mangrove forest vegetation data was conducted using purposive sampling (systematic plot) technique. The data used in the analysis of damage to mangrove forest ecosystems is the RBI Sheet Polewali Map Scale 1: 50000 BAKOSURTANAL in 1999, SPOT 4 Image in 2014, SPOT 4 Image in 2015, and Digital Globe Image Acquisition 6/9/2016. Data analysis and processing using the Arc-GIS program to analyze SPOT images, overlay and map making using Geographic Information System (GIS) applications, and descriptive analysis for the bio-physical data of mangrove vegetation. Data analysis of mangrove vegetation area in Mampie showed that overall from 1999 to 2016 the area of mangrove coverage experienced a shrinkage of 10.31 ha, namely 35.23 ha (1999) to 24.92 ha (2014). There is one thing that is quite encouraging that in the following year (2015) mangroves in the Mampie area expanded back to 0.58 ha ie to 25.50 ha but shrank back to 0.29 ha the following year (2016). Mampie Beach’s total mangrove area became 25.21 ha. The mangrove forest area in Mampie leaves only a few species of mangrove, the most dominating is Avicennia marina (Forsk.) Vierh.
