The purpose of this Community Service is to apply the research results of the proposer team's research for community empowerment in Pante Ceureumen District, West Aceh. Research results are applied to the activity program MERDEKA 74 "(Minapadi Together with Local Fish 7 Species and 4 Legowo) which is a system of planting rice by cultivating fish in one rice field simultaneously. This program aims to increase farmers' income with high rice yield productivity and increase local fish production. The activity was carried out for 6 months at the Pante Ceureumen District, West Aceh. The results observed included rice production and fish production in the Minapadi system. The production of 2: 1 legowo planted rice has a significant effect on the parameters of rice production, namely (16.17 kg /Ha). Meanwhile, the production of cultivated fish (7 species) are catfish, bileh fish, tilapia, goldfish, catfish, catfish and giant prawns. The 7 species are able to develop and be cultivated well.

Untuk mempersiapkan dan mematangkan pemahaman siswa menghadapi new normal, perlu dilakukan edukasi dan eksekusi secara serius terkait penerapan protokol kesehatan, sehingga tidak hanya sekedar narasi berupa perintah penerapannya, namun memberikan pemahaman secara mendalam dan praktik kepada siswa sebagai bentuk kepedulian dan kesadaran diri dalam siswa setelah ia memahami maksud dan tujuan dari penerapan protokol kesehatan itu sendiri. Sasaran dalam kegiatan ini adalah siswa dan guru di SD Negeri 1 Masiri. Metode pelaksanaan kegiatan terdiri dari 3 tahap kegiatan, di antaranya 1) kegiatan sosialisasi yang dilakukan melalui metode ceramah terkait panduan pelaksanaan pembelajaran tatap muka bagi daerah zona hijau dimasa pandemik melalui penerapan protokol kesehatan; 2) kegiatan simulasi, dengan mempraktikkan secara langsung tahapan pelaksanaan protokol kesehatan secara runtut dan tepat; 3) kegiatan evaluasi, pembagian masker gratis, hand sanitizer, dan sabun cuci tangan. Kegiatan ini dianggap penting, merujuk pada beberapa pengabdian serupa yang belum menekankan pada pembentukan kesadaran dalam diri anak dan menanamkan kebiasaan baru secara runtut terkait protokol kesehatan. Hasil Pengabdian kepada masyarakat menunjukkan hasil yang cukup memuaskan, berdasarkan analisis perbandingan sebelum dan setelah kegiatan dilaksanakan menunjukkan adanya perubahan perilaku ke arah positif.

Hammerhead shark is a type of predator shark belongs to the family of Sphyrnidae. This shark is so aggressive in hunting prey such as fish, squid, and shrimp. The hammerhead shark in Indonesia is included in Appendix II of CITES and has been a special concern in the field of capture fisheries. The aim of the study was to see the size spread, the number of catches, the first size caught, the age growth and the genital ratio of the hammerhead sharks caught with the base fish net. The study was conducted from October to December 2019. The shark measurement was performed once in 2 weeks. Sharks caught by the gills of the base (buttom gilt net) were measured using a roll meter. The collection of hammerhead sharks included total length (TL), number of catches and genital ratio. The analysis was done descriptively using the ELEFAN I existing on Sofwere FiSAT II. The results showed that the hammerhead sharks caught with an gill net of 65 tails from October to December 2019 were taken on the male genital. The total size spread of female malletic sharks were between 61.5-131.5 cm and male hammering sharks between 61.5-111.5 cm. The morphologically spread of the female hammerhead was relatively longer than the male shark. The male hammerhead shark was first captured at a length of 117.9 cm and a female hammerhead shark at a size of 106.2 cm. Hammerhead shark growth by following the curve of von Bertalanffy mallet were male Lt = 138,08 (1-exp (-0.480 (t + 0.0487)) and female mallet shark Lt = 138,08 (1-exp (-0.430 (t + 0.0434)). Such equations can be known by using the relationship curve model between the age and length of fish.

The mangrove species Sonneratia alba is one of the plants that has good bioactive compounds and very easy to find. However, the content of bioactive compounds and nutrients from a plant is strongly influenced by internal and external factors. The study was conducted with the aim to know the proximate content, yield and antioxidant activity of S. alba fruit from Lhok Bubon Village, Samatoga District, West Aceh Regency. The extraction method used methanol, ethyl acetate and n-hexane as solvent with antioxidant test using DPPH solution (2,2-Diphenil-2-picryl hydrazil). The results of the study showed the proximate content consisted of water 30.71%, ash 5.06%, fat 8.59%, protein 3.48% and carbohydrate 52.16%. Meanwhile, the yield showed ethyl acetate solvent had the highest yield (69.11 ± 13.27%), then followed by n-hexane (68.38 ± 13.21%) and methanol (64.44 ± 14.78%). Furthermore, for the antioxidant activity of S. alba fruit from Lhok Bubon Village, Samatoga District, West Aceh Regency, overall it was classified as very strong IC50 < 50 ppm).   Spesies mangrove Sonneratia alba merupakan salah satu tanaman yang memiliki senyawa bioaktif yang baik dan sangat mudah ditemukan. Namun kandungan senyawa bioaktif dan nutrisi dari suatu tanaman sangat dipengaruhi oleh faktor internal dan eksternalnya. Penelitian dilakukan dengan tujuan untuk mengetahui kandungan proksimat, rendemen dan aktivitas antioksidan buah S. alba dari Desa Lhok Bubon Kecamatan Samatoga Kabupaten Aceh Barat. Metode ekstraksinya menggunakan pelarut methanol, etil asetat dan n-heksana dengan uji antioksidannya menggunakan larutan DPPH (2,2-Diphenil-2-picryl hydrazil). Hasil penelitian mendapatkan bahwa kandungan proksimatnya terdiri dari kadar air 30.71%, kadar abu 5.06%, kadar lemak 8.59%, kadar protein 3.48% dan kadar karbohidrat 52.16%. Sementara untuk rendemen menunjukkan bahwa pelarut etil asetat memiliki rendemen tertingginya (69.11 ± 13.27%), kemudian diikuti oleh n-heksana (68.38 ± 13.21%) dan methanol (64.44 ± 14.78%). Selanjutnya untuk aktivitas antioksidan buah S. alba dari Desa Lhok Bubon Kecamatan Samatoga Kabupaten Aceh Barat secara keseluruhannya tergolong sangat kuat (IC50 < 50 ppm).
