Abstract

Ketam Kenari adalah spesies ketam terbesar di dunia. Penelitian ini bertujuan untuk menganalisa hubungan panjang dan berat ketam Kenari (Myos Ambower). Pengambilan sampel dilakukan dengan dua periode yang berbeda yaitu pengambilan sampel pada pukul 20.00-22.00 WIT dan pada pukul 23.00-02:00 WIT. Metode pengumpulan data yang digunakan dalam penelitian ini yaitu purposive sampling. Dari hasil penangkapan dilakukan identifikasi jenis kelamin dan pengukuran panjang (Cp+r) dan berat tubuh. Jumlah sampel ketam kelapa yang diperoleh selama penelitian berjumlah 100 ekor yang terdiri dari jantan 60 ekor dan betina 40 ekor. Hasil penelitian ini diperoleh kisaran panjang ketam kenari jantan 4 -13 cm dan betina yaitu 4 − 11 cm. Kisaran berat ketam kenari jantan 300− 2000 gram sedangkan yang betina 300-1500 gram. Dari hasil yang di peroleh pada penelitian ini nilai b 2.2219 pada ketam kenari memiliki pola pertumbuhan yang bersifat alometrik negatif menunjukan adanya hubungan (b < 3) berarti pertambahan panjang tubuh lebih cepat dari pada pertambahan berat tubuh.

Abstract

As a typical ecosystem for coastal areas, mangrove ecosystems have many functions and benefits in supporting the sustainability of other ecosystems involved in it. Mangrove forests play an important role in stabilizing coastlines and helping to reduce the impact of natural disasters such as tsunamis and hurricanes. This study aims to determine the extent of mangrove cover in Klablim Vilage, Klaurung District. The method used in this research is line transect, which is carried out by making a perpendicular line to the land by making maps or plots. One of the advantages of using this method is that it is more efficient. This method is faster, requires less equipment, and requires fewer observers. The results of this study found the diversity of mangrove species in Klablim Village, Klaurung District, consisting of Rhizophora sp, Xylocarpus sp, Bruguier asp and Soneratia sp. The relative frequency of mangroves found in Klablim Village, Klaurung District, is Rhizophora sp 62.5%, Xylocarpus sp 12.5%, Bruguiera sp 12.5% ​​as well as Soneratia sp 12.5%. The relative density of mangroves found in Klablim Village, Klaurung District, for the species Rhizophora sp 68%, Xylocarpus sp 16%, Bruguierasp 8% and Soneratia sp 8%. The relative cover for Rhizophora sp species was 92.3%, Xylocarpus sp 5.11% species, Bruguiera sp 1.27% and Soneratia sp 1.27%.

Abstract

This community service program aimed to strengthen household food security on Pulau Soop by utilizing home yards and plastic bottles as planting media. The initiative addressed limited land availability and increasing plastic waste on the small island. Through training on converting plastic bottles into planting containers and cultivating vegetables at SMP Negeri 9 Pulau Soop, students gained knowledge and practical skills in recycling, appropriate technology, and simple cultivation methods. The results show improved student understanding, active participation, and the establishment of a school mini garden as an urban farming model. The program effectively supported environmental education, reduced plastic waste, and enhanced yard-based food security in the small island community.

Abstract

Melanotaenia Fredericki (Fowler, 1939) Subordo Melanotaeniodei, Ordo Arheriniformes adalah jenis ikan air tawar, tergolong ikan hias yang memiliki sebaran di daerah Sorong dan sekitarnya. Penelitian ini bertujuan untuk menganalisis karakter morfologi dan karakte rmorfoanatomi (gonad) Ikan Rainbow Sorong (Melanotaenia fredericki) asal Sungai Hutan Lindungdan Sungai Malasaum. Metode yang digunakan yaitu observasi lapangan dan analisis laboratorium dengan menggunakan Statistika V.8 Scater Flots dan Statistika Uji T Komparatif. Berdasarkan hasil dapat disimpulkan bahwa analisis morfologi menunjukkan adanya 5 (lima) karakter yang saling tumpang tindih antara populasi asal Sungai Hutan Lindung dan populasi asal Sungai Malasaum (tidak ada perbedaan mencolok). Populasi pada Sungai Hutan Lindung mencirikan karakter batang ekor lebih tinggi dan karakter gonad lebih kecil. Sebaliknya populasi pada Sungai Malasaum mencirikan karakter batang ekor lebih pendek dan karakter gonad lebih besar.
