Terumbu karang merupakan suatu ekosistem yang sangat kompleks dengan keanekaragaman hayati yang tinggi. Acropora sp. merupakan salah satu terumbu karang yang umum mendominasi daerah tropis karena sifatnya yang mudah berkembang dan ketahanannya terhadap lingkungan. Banyak faktor yang mempengaruhi kehidupan karang Acropora sp., salah satunya adalah nitrat dan fosfat. Nitrat dan fosfat pada polip karang dibutuhkan oleh Zooxanthelhae untuk melakukan proses fotosintesis. Hasil dari proses fotosintesis seperti asam amino akan digunakan oleh karang untuk proses kalsifikasi atau pertumbuhan.Tujuan penelitian ini adalah untuk mengetahui profil kandungan nitrat dan fosfat pada polip karang Acropora sp., dan mengetahui persentase penutupan terumbu karang di pulau Menjangan Kecil. Metode yang digunakan dalam penelitian ini adalah metode survei yang bersifat deskriptif, sedangkan metode yang digunakan dalam pengambilan sampel karang adalah metode purposive. Sampel karang Acropora sp. Diambil secara random pada kedalaman 1-2 meter dan pada kedalaman 3-5 meter, pada masing-masing kedalaman terdapat 4 titik sampling, dan pada tiap titik sampling tersebut diambil 2 sampel karang Acropora sp. Penelitian ini menganalisis kandungan nitrat fosfat dan jumlah bakteri nitrifikasi pada karang Acropora sp. Hasil penelitian menunjukkan bahwa terjadi fluktuasi kandungan nitrat dan fosfat pada polip karang. Kandungan nitrat sebesar 14.78 â€“ 21.09 %Â atau setara dengan 147.800 â€“ 210.900 mg/L dan fosfat sebesar 23.40 â€“ 28.18 % atau setara dengan 234.000 â€“ 281.800 mg/L. Persentase penutupan terumbu karang pada stasiun I adalah 71,6 %, termasuk dalam kategori baik, sedangkan persentase penutupan terumbu karang pada stasiun II adalah 75 %, termasuk dalam kategori sangat baik. Semakin banyak kandungan nitrat dan fosfat pada polip karang, maka semakin tinggi persentase penutupan terumbu karangnya.

Coral is an ecosystem in the coastal area which plays an important role in controlling nutrient cycle in the sea. This research aimed to study the the nitrogen concentration in coral and to analyze the influence of nitrogen fixing bacteria on the concentration of nitrogen in coral. The research was carried out by field observation, by taking coral reef samples and analyzed in the laboratory for its nitrogen concentration and number of nitrogen fixing bacteria. Data analysis was carried out by ANOVA and regression. The analysis resulted that there was a significant difference of nitrogen concentration in massive and branching corals. However, there is no significant correlation between the sampling location and types of coral on the density of nitrogen fixing bacteria, both Nitrosomonas sp. and Nitrobacter sp. Regression analysis showed that the concentration of nitrogen in coral tissue was not significantly related to the density of nitrogen fixing bacteria. The result of this research implies that the concentration of nitrogen in the coral tissue may be affected by many other factors.

The management of conservation areas includes surveillance and monitoring activities (patrols) carried out by supervisory community groups (pokmaswas) using the Smart Patrol method. Patrol activities aim to determine the utilization pattern and level of zoning compliance in the marine conservation area of Gili Balu Aquatic Tourism Park. Patrol activities are carried out in 2021 as many as 8 times with an average of 1 time every month. The average time used to make observations ±5 hours. During the activity, 32 points of utilization of capture fisheries were found by 36 fishermen. The composition of the fishing gear used is 78% fishing line, 10% drift gill nets, 9% squid angling, the remaining 3% arrows. Fishermen's catches are dominated by soft-skin animals (81%), small pelagic fish (16%), and reef fish (3%). The pressure level of TWP Gili Balu utilization is relatively high with the highest value found on Belang Island, which is 32 people per 4 km2. The compliance rate in the core zone is relatively high with a value of 81% and falls into the excellent category, as well as in the utilization zone it is quite high at 42% and belongs to the category of quite good. The level of knowledge or utilization of the Gili Balu TWP area is included in the sufficient (moderate) category, where 41% of users know about the existence of the Gili Balu TWP conservation area and 59% of people who do not know the existence of the Gili balu TWP conservation area and the rules in it. Pokmaswas who are actively involved in surveillance and monitoring activities are Pokmaswas Liang Kuru of Senayan village, Pokmaswas Bua Lawah of Poto Tano village. However, it is still necessary to carry out regular supervision and monitoring at locations that are prone to zoning violations and socialization related to the existence of the Gili Balu TWP conservation area and the zoning rules in it.

Labuhan Haji Beach has a problem with piles of plastic waste on the beach. According to observations made by the Coastal Environmental & Fisheries Research Institute (CEF), the plastic waste found on Labuhan Haji Beach amounts to 9.18 tonnes or around 0.77 kg/m2. Since 2018 efforts have been made by the Government and stakeholders to deal with this problem, starting from making regulations, cleaning up, to anti-plastic waste campaigns. However, these efforts have not had a significant impact both physically and non-physically. The purpose of implementing this dedication is to form institutions within the scope of the Haj harbor community; the creation of trash trap facilities on the river route to Labuhan Haji Beach. The method of implementing this service is divided into 6 (six) activities, namely deliberation and coordination, outreach, making trash traps, installing trash traps, operating trash traps, monitoring and evaluation. This activity is expected to provide a solution to prevent plastic waste from going into the sea. The results achieved in this community service activity were being able to gather several stakeholders such as DLHK of NTB Province, DLHK of East Lombok Regency, Pemdes Labuhan Haji which had never before had joint coordination and deliberation activities in alleviating waste problems at Labuhan Haji Beach, providing outreach to the residents of Labuhan Haji Village who live on the banks of the river, are able to build 1 (one) Trash Trap at the mouth of the Labuhan Haji River which has been able to dispel Â± 10 (ten) tons of waste with a total number of volunteers of 100 people from 10 agencies in the Regency East Lombok. Labuhan Haji Village already has a trash barrier facility in the form of a trash trap. The impact felt after this service activity was carried out was that 90% of the garbage heading to Labuhan Haji Beach could be blocked.

The purpose of this study was to analyze the biomass production and bioactivity of sponge symbiont mushroom extracts on modified media using experimental laboratory methods. Biomass was calculated by weighing the wet weight of the symbiont mushroom mycelium and then tested for antibacterial activity with an extract concentration of 500 µg/disk. The results of this study, namely the weight of F.solani mycelium on MKD + MGV media was 10 grams, the mass of mycelium on MKD media was 9 grams, while the mass of mycelium on MEB standard media was 9.7 grams. The yield weight of the F.solani crude extract cultured on MKD + MGV media was 0.0386 grams or 0.3860% of the wet weight, on MKD media it showed that the crude extract weight was 0.0276 grams or 0.3067% of the wet weight, while on MEB the crude extract weight was 0.0119 grams or 0.1190% of the wet weight. The results of the antibacterial test showed that the largest inhibition zone for MDR (Meticilin Resistant Staphylococcus aureus) bacteria was F.solani crude extract cultured on MKD + MGV media, namely 25.83 ± 3.37 mm, F.solani cultured on MKD media of 22.10 ± 2.51 mm , while F. solani cultured on MEB media was 19.00 ± 0.52 mm. The results of the mass culture of the fungus Fusarium solani on modified media showed that the mushrooms cultured on MKD + MGV media had greater biomass, crude extract and antibacterial activity compared to MKD and MEB culture media.

The Gili Sulat and Gili Lawang Marine Recreation Park (TWP) has a significant diversity of reef fish, but fishing activities threaten its stock. This research aims to estimate the stock condition of reef fish using a length-based stock assessment approach and Spawning Potential Ratio (SPR) analysis. Data were collected from two fish landing sites throughout 2023, covering fish species, catch results, and fish length data. A CPUE (Catch Per Unit Effort) analysis was conducted to assess fishing efforts and catches, while SPR was used to evaluate the stock condition of the fish. The research results show that 151 species of reef fish were caught, with three dominant species: Naso thynnoides (35%), Acanthurus mata (33%), and Caesio caerulaurea (32%). The SPR values of these three species were above 30%, indicating relatively healthy stocks (Naso thynnoides 58%, Acanthurus mata 43%, Caesio caerulaurea 34%). However, the exploitation rate of Acanthurus mata indicates that this species is fully exploited (E=0.578), requiring strict management to prevent overfishing. In conclusion, most reef fish stocks are in good condition, but Acanthurus mata requires special attention. Fishing control and regular monitoring are recommended to maintain the sustainability of reef fish stocks in TWP Gili Sulat and Gili Lawang.

Ketersediaan data panjang badan ikan yang akurat menjadi elemen penting dalam pengelolaan perikanan berkelanjutan, khususnya untuk komoditas ekonomis seperti kakap dan kerapu di Provinsi Nusa Tenggara Barat (NTB). Namun, rendahnya partisipasi nelayan dan pengumpul ikan dalam pengumpulan data biologis disebabkan kurangnya pemahaman teknis. Tujuan dari kegiatan edukasi ini adalah nelayan dan pengumpul ikan kakap dan kerapu memiliki pemahaman tentang bagian-bagian tubuh ikan, jenis pengukuran (panjang total, panjang standar), cara penggunaan alat ukur, serta metode pencatatan dan pelaporan data yang sesuai dengan standar ilmiah. Metode pelaksanaan dilakukan pada April 2025 melalui pendekatan andragogi berbasis partisipasi, yang meliputi sosialisasi, penyampaian materi, dan demonstrasi. Hasil kegiatan menunjukkan bahwa peningkatan pengetahuan nelayan dan pengumpul ikan kakap dan kerapu di Pasar Ikan Tanjung Luar dalam mengenali bagian tubuh ikan, menentukan jenis panjang (total, standar, cagak), menggunakan alat ukur dengan benar, serta melakukan pencatatan data secara sistematis. Edukasi ini juga menumbuhkan kesadaran pentingnya mematuhi ukuran minimum tangkap sesuai regulasi daerah, sehingga mendukung ketersediaan stok ikan secara berkelanjutan. Kesimpulannya, kegiatan edukasi pengukuran panjang badan ikan ini efektif meningkatkan literasi teknis masyarakat pesisir dan diharapkan mampu memperbaiki kualitas data perikanan di tingkat tapak. Ke depan, diperlukan pendampingan rutin, penyediaan sarana ukur yang memadai, serta pelatihan lanjutan agar praktik pengukuran dan pendataan dapat dilaksanakan secara konsisten oleh nelayan dan pengumpul ikan kakap dan kerapu di Pasar Ikan Tanjung Luar.
