Abstract

The Teluk Awang Fishery Port (PP) is located in Mertak Village, Central Lombok Regency, which has the potential to develop as a center of economic growth with a fishery business base. It has a good geographical location because it is protected from waves coming from the Indian Ocean. Currently the Central Government, West Nusa Tenggara Provincial Government and Central Lombok Regency Government are jointly developing Awang Bay as a fishery business center by building a fishing port that can accommodate fishing vessels operating in WPPNRI 573 and 713. This study will look at fish resources ( SDI) in PP Teluk Awang uses the Participatory Action Research (PAR) method which actively involves all relevant parties. The results of the research show that the SDI that was landed in PP Teluk Awang during 2018-2020 as much as 3,559,483 kg was still dominated by pelagic and demersal fish, such as Cakalang fish (62.67%), Layang (10.77%), Tongkol ( 8.29%), Lemadang (6.34%), Tuna (5.42%), Baby Tuna (3.88%), Marlin (1.48%) and other fish (1.15%). The recorded fleet of ships is 27 units with a size of 8-25 Gross Tonnage (GT). The results of this study are expected to be a recommendation related to policies in managing the potential of SDI landed in PP Teluk Awang with the concept of sustainable fisheries.

Abstract

Kebijakan pemerintah membuka ekspor bibit lobster tahun 2020 disambut gembira nelayan Lombok tengah, karena mereka bisa menangkap bibit lobster kembali. Upaya mengendalikan stok bibit lobster di alam agar berkelanjutan perlu data kelimpahan bibit lobster. Penelitian ini bertujuan mengetahui kelimpahan bibit lobster di Teluk Bumbang Kabupaten Lombok Tengah. Periode penelitian mulai September 2020 hingga Februari 2021.  Titik sampling di 3 lokasi yaitu  bagian dalam,  bagian tengah dan bagian luar dari teluk Bumbang. Penangkapan bibit lobster menggunakan alat tangkap tradisional yaitu pocong. Jenis bibit lobster yang tertangkap yaitu lobster mutiara (Panulirus ornatus) dan lobster pasir (P. Homarus).  Hasil tangkapan bibit lobster paling banyak pada bagian tengah Teluk Bumbang. Tingginya kelimpahan bibit lobster di bagian tengah teluk disebabkan oleh ombak kecil, perairan relative lebih dalam, serta tidak banyak aktivitas nelayan. Terdapat fluktuasi hasil tangkapan bibit lobster pada setiap periode penangkapan. Hal ini dipengaruhi oleh tinggi rendahnya pasang surut dan suhu perairan. Pengaruh pasang surut terhadap kelimpahan bibit lobster lebih dipenagruhi efek pasang surut berupa arus dan gelombang. Suhu perairan berubah dari dingin di awal penelitian menjadi lebih hangat di akhir penelitian. Pada saat suhu berubah dari dingin ke panas (hangat) terjadi peningkatan kelimpahan bibit lobster yang signifikan.

Abstract

Today's mangrove ecosystem is increasingly under pressure, mainly due to the conversion of mangrove land into aquaculture, tourism, and industrial areas. At the same time, the mangrove ecosystem has a very vital role in life. Efforts have been made to slow down the degradation rate of the mangrove ecosystem, including by replanting activities (reforestation). Mangrove planting activities are often constrained by the lack of healthy seeds or a mismatch between the seeds and the planting environment. It causes the planted mangrove seedlings not to be able to grow appropriately and even die. This community service activity aims to educate and assist the community in Poton Bako Hamlet, Jerowaru Village, Jerowaru District, East Lombok Regency regarding mangrove nursery techniques, especially R. mucronata and S. alba species, properly and correctly. The method used is using booklet media and direct practical assistance. Moreover, the community listens and practices what has been conveyed regarding nursery procedures. The results of this activity received high enthusiasm from the community, and the community felt its usefulness. This mentoring activity requires follow-up in the form of continuous control and assistance so that future nursery programs carried out independently by the community can continue and run optimally. In the future, it is hoped that the community's independence to carry out mangrove nurseries can run well. Thus what has been obtained by the community can be transmitted to others so that mangrove conservation is maintained.

Abstract

Rote Island and its surroundings are included in the Savu Sea Marine National Park (TNP) area and are administratively included in the Rote Ndao Regency, East Nusa Tenggara (NTT) Province. The waters of the area have high potential for coral reef ecosystem resources and are an important for the marine biota. But when the condition is under pressure due to anthropogenic and natural influences. Therefore it is necessary to carry out routine observations related to the condition of the community structure and its potenstial natural recruitment. Observations were made on 26-28 September 2021 at 12 observation stations. The observation method used was the belt transect method with 3 repetitions (20 m) with an area of 60 m2. Data collection using SCUBA equipment at a depth of 5-7 m on the reef flat. The results of the study found a total of 37 hard coral genera and the highest species richness was in Daiama 2 (30 genera) and the lowest was in Oelua and metina (13 genera). The dominant hard coral genera found were the Porites genera. Furthermore, the potential for natural recruitment of hard coral tillers reaches 21%. The highest potential for natural recovery is at Sotimori 1 (station 3) and the lowest at Boni (station 12). In general, the hard coral community structure at the observation site is in a stable condition with good natural recruitment potential.

Abstract

Coral reefs are under pressure from climate change and various factors, putting them at risk of a decline in resilience. This heightened vulnerability increases the likelihood of reaching a tipping point with the next shock or stressor. Identifying early warning indicators for tipping points is crucial for proactive coral reef management. Therefore, this study aims to comprehend the coral reef health parameters considered important and feasible for collection by local stakeholders, as well as identify factors facilitating the implementation of a community-based monitoring and early warning system in a fishers-dominated community. The approach used was Participatory Action Research. The results reveal twelve priority parameters deemed necessary by the local community and feasible for collection by local stakeholders, including the local community, university, and non-governmental organization. The identified parameters are: coral bleaching, visibility, temperature, pH, dissolved oxygen, salinity, current, coral percent cover, fish community, macroalgal canopy cover and composition, benthic composition, and plankton. Interpretive structural model and MICMAC analysis show nine enabling factors supporting the development of a community-led coral reef health monitoring and early warning system. These factors include team motivation, training and team capacity, connection with government, connection with university, facilitation by NGOs, supporting regulations, operational funds, access to equipment, and operation and maintenance of equipment. Team motivation stands out as the most influential factor, with strong driving power and dependence, making it crucial to manage as actions on it will have ripple effects on other factors.
