Abstract

Research has been carried out on the analysis of the environmental conditions of seaweed cultivation in the Pulo Raya area of Aceh Jaya Regency, Aceh Province. Aceh Province is the westernmost province of the Indonesian archipelago. Geographically, Aceh is a peninsula area of the island of Sumatra which is directly bordered by the Indian Ocean so that Aceh has several small islands. With this condition, it has the potential to be used as a place for seaweed cultivation. An analysis of environmental conditions is needed to produce good quality seaweed. Examination parameters include pH, temperature, heavy metal content, COD and salinity. Sample examination is carried out based on Standar Nasional Indonesia (SNI) No. 7578.1: 2010 and Decree of the Minister of Environment (KemenLH) No. 51: 2004. The results obtained showed a pH level of 6.22; temperature of ± 28 oC; levels of lead metal ions (Pb (II)) 0.001 ppm and copper (Cu (II) metal ions of 0.002 ppm; The COD level is 137 ppm and the salinity level is 28.75 ppm. With the results of the chemical analysis obtained, the Pulo Raya area is feasible to become a seaweed cultivation area.

Abstract

Sintesis pasir besi lampanah Aceh Besar menjadi nanopartikel magnetite besi oksida menjadi tujuan utama dalam penelitian ini untuk mengamati struktur Kristal yang dimilikinya. Sifat Kristalin yang tinggi ketika terjadi perubahan fisis dari material menjadikan kajian ini layak untuk diteliti. Melalui teknik pemisahan menggunakan magnet batang, pasir besi dari alam dipisahkan dari pengotor lalu disaring dengan ayakan yang berukuran 200 mesh. Pasir besi berkualitas baik disintesis dengan menggunakan metode kopresipitasi yang mana pasir besi dilarutkan ke dalam 12 M Asam Klorida 37 % v/v. Larutan tersebut diaduk dan disaring, kemudian hasil larutan dicampurkan dengan 6,5 M  ammonia dengan perbandingan ratio campuran 1:7. Melalui proses aduk dan saring, hasil endapan kemudian dikeringkan.  Berdasarkan hasil uji XRD, SEM dan Cacah magnetik didapati karakteristik nanopartikel magnetite besi oksida. Berdasarkan data XRD, didapati  sudut 2 thetanya 30,105o; 35,45o dan 62,585o dengan indek miller [hkl]: [220], [311] dan [440]. Nilai [hkl] ini menunjukkan bahwa nanopartikel magnetite dari pasir besi Lampanah memiliki struktur kristal Kubik dengan struktur kisinya FCC (Face Center Cubic). Berdasarkan uji SEM, morfologi nanopartikel magnetite besi oksida berbentuk tidak seragam dengan ukuran partikel yang relatif tidak sama berada dalam rentang  800 nm sampai 3000 nm. Sedangkan untuk cacah medan magnetik dalam bentuk pasir besi didapati nilai cacahannya 0,03 mT sedangkan dalam bentuk nanopartikel magnetite diperoleh 0,022 mT. Kesimpulan yang didapati bahwa struktur Kristal dari pasir besi Lampanah semakin terlihat ketika ukuran besi oksida menjadi nanopartikel magnetite. Langkah pengoptimalan dalam preparasi pasir besi menjadi nanopartikel magnetite diperlukan agar ukuran partikelnya di bawah < 100 nm sehingga dapat diaplikasinya dalam bidang elektronik, kesehatan dan sebagainya.
