Seagrass beds are potential marine resources to be utilized, and ecologically, seagrass beds are some of the important functions of the coastal area. Many organisms are ecologically and biologically very dependent on the presence of seagrasses. The ecosystem is an important food source for the organism by many sea organisms that use it as a spawning place. This study aims to determine the diversity of fish in seagrass beds in Padaratan Beach, Sarudik Subdistrict, Central Tapanuli Regency. A gillnet is used to obtain fish samples at three observation stations during the period from mid-March to April 2018. Fish diversity can be agreed by looking at the composition of fish species and diversity index. The results of this study show the total number of fish obtained, 196 individuals, consisting of 12 families and 14 species. The highest number of fish catches is at Station II with a total catch of 70 individuals. The highest relative abundance of stations I, II, and III with values â€‹â€‹of 22.96%, 20.01%, and 23.07% are found in fish species from the family Hemaramphidae with Zenarchopterus gilli species. The diversity index value (H') of all observation stations shows that species richness is in a moderate condition with values â€‹â€‹of the station I (2,339), station II (2,439) and station III (2,367). While the uniformity value (e), shows the value of station I (0.866) station II (0.924) and station III (0.897) observations are in a stable condition (0.75 <e d â€1.00). Such conditions indicate that the distribution at each observation station is equitable.

Ikan tongkol komo (Euthynnus affinis) merupakan salah satu komoditas ekonomis penting yang tertangkap di perairan Laut Jawa sebelah utara Jawa Timur. Tingkat pemanfaatan ikan tongkol komo terus meningkat sehingga perlu dikelola dengan baik untuk keberlanjutannya agar tidak mengalami penurunan stok. Tujuan penelitian ini untuk mengevaluasi status sumberdaya ikan tongkol komo dengan mengestimasi parameter populasi dan rasio potensi pemijahan dengan pendekatan ukuran panjang ikan, digunakan sebagai titik acuan biologis dalam menentukan kondisi stok ikan. Sebanyak 1995 data ukuran panjang ikan yang dikumpulkan secara acak selama bulan Februari hingga Juni 2021 di Pasongsongan, Jawa Timur. Metode ELEFAN digunakan untuk menentukan parameter populasi yaitu pertumbuhan, kematian, dan laju pemanfaatan. Analisis rasio potensi pemijahan dilakukan dengan menggunakan parameter populasi, dan parameter biologi yang didapatkan dari hasil penelitian sebelummnya dengan paket LB-SPR. Hasil analisis pertumbuhan von Bertalanffy ikan tongkol komo dari penelitian ini diperoleh persamaan Lt= 60,9 (1-e-0,41(t-0,19)). Rata-rata tongkol komo yang tertangkap belum matang gonad (Lc<Lm), tekanan penangkapan dalam kategori tinggi dan rekrutmen dalam stok terganggu. Hal ini terlihat bahwa rasio mortalitas penangkapan relatif (F/M) = 2,51, laju eksploitasi (E) = 0,71, dan SPR = 20%. Oleh sebab itu diperlukan penyusunan pengelolaan yang efektif untuk keberlanjutan stok ikan tongkol komo.Kawakawa (Euthynnus affinis) is one of the important economic commodities caught in the sea waters north of East Java. The utilization rate of kawakawa is quite high, so it is necessary to regulate the sustainability of kawakawa stock to maintain it. This study aimed to evaluate the status of kawakawa fish resources by estimating population parameters and spawning potential ratio (SPR) with a fish length approach, used as a biological reference point in determining fish stock conditions. 1995 data on the length of fish were collected randomly from February to June 2021 in Pasongsongan, East Java. The ELEFFAN method was used to determine population parameters: growth, mortality, and utilization rate. SPR analysis was carried out using population and biological parameters obtained from previous studies with the LB-SPR package. The results of von Bertalanffy's growth analysis for kawakawa from this study were written with the equation Lt= 60.9 (1-e-0.41(t-0.19)). The average kawakawa caught was immature gonads (Lc<Lm), fishing pressure was also still high, and recruitment in stock was disrupted. It can be seen that the relative fishing mortality ratio (F/M) = 2.51, exploitation rate (E) = 0.71, and SPR = 20%. Therefore, it is necessary to develop effective management for the sustainability of kawakawa stocks.

The Nias Islands are a group of islands located on the west coast of Sumatra. Nias Island is the main and largest island on the West Coast of Sumatra. Information on the distribution and potential status of mangroves in the Nias Islands has been reported, but it is limited to a narrow area and not yet comprehensive throughout the Nias Islands. This study aims to determine the distribution and ecological status of mangroves in the Nias Islands. The research location was divided into two observation areas, namely 15 points on Nias Island and 23 points on the southern part of Nias. The research was carried out in June 2019 and June 2021. Mangrove sampling was carried out using the "spot check" method which refers to Bengen (2004). The results showed that the mangroves found in the Nias Islands consisted of 22 primary mangrove species and 9 secondary mangrove species. Rhizophora apiculata, Rhizophora mucronata, and Xylocarpus granatum are the most abundant mangrove species and are commonly found in the Nias Islands. The thickness of mangroves in the Nias Islands ranges from 15 â€“ 880 m. The density of mangroves found reached 350-4,360 ind/ha. Mangrove cover reaches 0.08-31.62 m2/ha. The results of the analysis of the significant value of mangrove species show that Rhizophora mucronata and Rhizophora apiculata have a large influence and role in the mangrove vegetation community on Nias Island. Mangroves in the Nias Islands are categorized as damagedâ€“good. The good category was found in South Nias, Belukar Bay, and Bengkuang Bay, while the damaged category was found in Lahewa Bay and Dalam Bay

Banjir yang terjadi secara berulang di Kabupaten Aceh Tamiang, khususnya di Desa Simpang Lhee, Kecamatan Manyak Payed, tidak hanya menimbulkan kerusakan infrastruktur, tetapi juga berdampak pada ketahanan pangan dan kesehatan masyarakat, terutama anak-anak. Kondisi pascabanjir sering menyebabkan menurunnya ketersediaan pangan, buruknya sanitasi, serta meningkatnya risiko penyakit infeksi yang dapat memperburuk status gizi balita. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mencegah penurunan status gizi anak pascabanjir melalui intervensi pemberian makanan bergizi serta edukasi gizi kepada orang tua. Metode yang digunakan adalah pendekatan aksi partisipatif dengan melibatkan tim pengabdian, kader Posyandu, dan perangkat desa. Kegiatan dilaksanakan pada 28 Februari 2026 di Desa Simpang Lhee dengan sasaran anak-anak yang terdampak banjir. Intervensi dilakukan melalui penyusunan dan distribusi 100 paket bubur bergizi berbahan dasar beras lokal yang diperkaya dengan protein hewani dan sayuran, serta pemberian air minum kemasan. Selain itu, dilakukan edukasi singkat mengenai pola asuh gizi darurat dan pembagian leaflet panduan gizi kepada para ibu. Hasil kegiatan menunjukkan bahwa pemberian makanan bergizi disertai edukasi kepada ibu dapat membantu mencegah penurunan status gizi anak dengan cara meningkatkan kesadaran ibu dari skor rata-rata 3,7 menjadi skor rata-rata 7,6 mengenai pentingnya pemenuhan gizi seimbang pada masa pemulihan pascabencana. Dengan demikian, intervensi gizi berbasis komunitas ini berpotensi menjadi strategi efektif dalam mendukung ketahanan pangan keluarga dan mencegah risiko gizi kurang maupun stunting pada anak di wilayah rawan bencana.
