Abstract

Waworada Bay is a water in Bima Regency which has long been used by some people for seaweed cultivation. Currently, seaweed farmers do not know the exact harvest period. This causes differences in the harvest period between farmers. So far, research on the harvest period in Waworada Bay is not yet available. The experiments aimed to assess the ideal period for harvest among the different growth periods (35, 45, and 55 days). This research was conducted in Waworada Bay, Langgudu District, Bima Regency, West Nusa Tenggara from November 2021 to January 2022. Observation variables were absolute growth, growth rate, wet and dry biomass, productivity and water quality (temperature, dissolved oxygen, salinity, pH, brightness, current). The seaweed cultivation method uses the longline method. The results showed that the highest absolute growth was found in the 55-day harvest period (115.70±1.71 g) and the lowest was in the 35-day harvest period (55.10±6.62 g). There was a significant difference in absolute growth between treatments. The growth rate was not significantly different between treatments with a value range of 1.09±0.24 to 3.55±1.39%day-1. Wet biomass ranged from 10,022±397.22 g 12m-1 (harvest period 55 days) to (6.306±149.92 g 12m-1) (harvest period 35 days). Dry biomass ranged from 670±34.12 g 12m-1 to 1.016±53.78 g 12m-1. Productivity ranges from 0.04 to 0.07 g dry weight m−2 days−1. The average water quality values are temperature 32.40 0C, dissolved oxygen 5.84 mg l-1, salinity 32 ppt, pH 7.30, brightness 2.50 m and current 14 cm sec-1.

Abstract

Coral reefs ecosystem degradation in Saleh Bay results from human impacts such as coral quarrying, dredging, dynamite fishing, tourist damage and run-off of sediment, ship groundings, fertilizer and pesticides as a result of changing land-use. The aim of this project is to improve coral reef ecosystems through coral transplantation. The primary objectives of coral transplantation are to improve reef `quality' in terms of live coral cover, biodiversity and topographic complexity. This coral reef transplantation project was carried out in the waters of Saleh Bay. This project was carried out from June to July 2024. The stakeholders involved were universities, village governments, NGOs (Yayasan Bentang Alam Nusantara) and the Labuhan Kuris Village community. The FGD method was used to collect information from stakeholders and determine the role of each stakeholder. Coral reef transplantation uses table-shaped iron media. The coral species planted are acropora sp. Coral transplants are placed in the waters of Saleh Bay. The result of this activity is that there are two coral reef transplant units. The type planted is Acropora sp. The success of this activity is due to the collaboration between community groups, government and NGOs. Based on the evaluation results during the activity, it can be concluded that the coral reef transplantation in this activity was successfully carried out with the indicator of the planting of two coral transplant units using a rectangular iron frame media (table). The success of this activity was due to collaboration between stakeholders.

Abstract

Tablolong Beach, Kupang, West Nusa Tenggara, has significant potential for sea cucumber aquaculture development. This study examines the environmental conditions, climatic factors, and local natural resources that support sea cucumber farming in this area. The results showed that Tablolong Beach has very suitable environmental characteristics for sea cucumber growth, including suitable water temperature and sufficient natural food availability. In addition, the local community has strong traditional knowledge on sea cucumber collection and cultivation. the purpose of this study was to determine the potential and types of sea cucumbers found around Tablolong beach. This research method is an experimental method where samples are taken by diving in the waters of Tablolong beach. Sea cucumber species found consisted of H. atra, H. leucospilota, H. fuscocinerea, and S. monoturbeculatus. This research provides an important basis for designing a sustainable sea cucumber aquaculture development plan in Tablolong Beach, integrating ecological, economic, and social aspects. By utilizing the natural potential and local knowledge, the development of sea cucumber aquaculture in this area can become a model for sustainable utilization of marine resources and support the livelihoods of coastal communities

Abstract

Desa Penyaring terletak di Kecamatan Moyo Utara, Kabupaten Sumbawa, Nusa Tenggara Barat, memiliki kawasan mangrove yang potensial untuk dikembangkan menjadi ekowisata bahari berbasis masyarakat. Kawasan ini berperan penting dalam melindungi pantai dari abrasi, sebagai tempat asuhan biota laut, dan penyerap karbon. Namun, masih ditemui keterbatasan dalam pemahaman masyarakat terhadap fungsi ekologis mangrove serta pengelolaannya. Penelitian ini bertujuan untuk mengidentifikasi sistem sosial ekologi (SES) pada kawasan wisata hutan mangrove Desa Penyaring. Metode yang digunakan meliputi pengamatan langsung, observasi partisipatif, wawancara, dokumentasi, serta pengukuran kualitas air berupa suhu, pH, dan salinitas. Hasil penelitian menunjukkan bahwa kawasan hutan mangrove Desa Penyaring memiliki suhu rata-rata 30C, nilai pH sebesar 7,8 yang masih sesuai dengan baku mutu air laut untuk wisata bahari. Dari aspek sosial, pengelolaan kawasan dilakukan oleh BUMDes dan Kelompok Sadar Wisata (POKDARWIS) dengan dukungan masyarakat dan pemerintah desa. Keberadaan wisata hutan mangrove mampu meningkatkan ekonomi masyarakat melalui kegiatan perdagangan, jasa wisata, serta menumbuhkan kesadaran terhadap konservasi lingkungan. Interaksi antara masyarakat dan ekosistem mangrove membentuk hubungan timbal balik yang saling menguatkan, menciptakan sistem sosial ekologi yang berkelanjutan di kawasan pesisir Sumbawa.Keywords: tourism, mangrove forest, social, ecology
