Gili Matra Aquatic Tourism Park has two conservation targets, namely biological targets and social, cultural and economic targets. Coral reef ecosystems, apart from being a conservation target, are also an attraction for tourists to visit. This research was conducted to determine the condition of the coral reef ecosystem to be used as the basis for the management of conservation areas. The research was conducted by collecting coral reef data either through surveys or secondary data from the results of previous studies. Coral reef survey using the standard Line Intercept Transect method. The survey results show that the condition of coral reefs in the utilization zone is better than the core zone. Live coral cover in the utilization zone reached 71% so it was categorized as good, while in the core zone it only reached 8% so it was categorized as bad. Coral reefs in the core zone are unable to recover even though the number of tourists has decreased during the Covid-19 pandemic. Therefore, the location of the core zone on Gili Air needs to be evaluated further so that the effectiveness of Gili Matra TWP management can be improved.

Marine debris is a material wasted intentionally or unintentionally into coastal and marine environment caused by human activities. Trash has become one of the biggest contributors to coastal and marine pollution that may disrupt the balance of aquatic ecosystem, reduce the aesthetic value of coastal and marine areas, and even disturb human health. This research was conducted to provide information regarding type, weight, and source of trash found around western coastal area of Ampenan Beach, Mataram City. Sampling spots which represented a condition of study area were determined using purposive sampling. Two research locations were chosen around Ampenan Beach, namely Penghulu Agung Beach and estuary of Jangkok River. Trash collection was done done using line transect method based on criteria determined from length of the coastline. The trash collected was then sorted, weighed, and identified based on trash classification system. Marine trash found around the research locations, both at Penghulu Agung Beach (Stasion 1) and at estuary of Jangkok River (Station 2), was dominated by plastics with an average number of trash pieces, respectively, of 7 item/m2 and 9 items/m2. Meanwhile, the weights of plastic trash found at station 1 and 2, respectively, were 29,76 gr/m2 and 213 gr/m2. The amount of plastic trash found at research locations might be the impact of human activities throwing the trash into the estuary and the beach.

Hubungan timbal balik yang terjadi antara hutan mangrove dan kegiatan budidaya ikan selayaknya mengharuskan para pembudidaya ikan untuk tetap menjaga sinergi keduanya tidak terganggu. Namun demikian, tidak semua pembudidaya ikan mengetahui akan hal ini, sering kali pembukaan lahan budidaya dilakukan dengan mengurangi kepadatan vegetasi mangrove secara drastis, tanpa diikuti oleh proses penanaman kembali. Hal ini juga terjadi pada salah satu daerah hutan mangrove di Nusa Tenggara Barat, yaitu di Dusun Cemare Kabupaten Lombok Barat. Lahan budidaya dibuka tanpa adanya usaha untuk menjaga agar vegetasi mangrove tetap dalam proporsi yang seimbang. Mempertimbangkan begitu besarnya peran mangrove secara ekologi menyebabkan harus segera dilakukan kegiatan penanaman kembali pada habitat mangrove yang telah rusak. Kegiatan ini akan dilaksanakan dengan melibatkan dosen, mahasiswa, dan kelompok pengelola setempat. Hasil pengabdian adalah telah tertanamnya bibit pohon mangrove di area terdampak, serta terjalinnya kerjasama dengan kelompok pengelola sumberdaya setempat untuk pemantauan pohon mangrove yang telah ditanam.

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.
