Abstract

Keberadaan air laut yang melimpah di Indonesia menjadikannya potensial sebagai sumber energi alternatif  dalam mengatasi keterbatasan pasokan energi untuk jangka panjang. Kajian ini bertujuan untuk mengetahui potensi air laut Aceh sebagai sumber energi alternatif. Proses pengukuran ini menggunakan dua plat elektroda yakni plat lempeng tembaga sebagai elektroda positif dan Plat Lempeng Seng sebagai elektroda negatif. Kedua plat direndamkan dalam wadah yang berisi air laut dan dirangkai secara seri. Volume air laut divariasikan mulai dari 600 ml, 800 ml dan 1000 ml. Sampel air laut diambil dari tiga Lokasi air laut yang berbeda yaitu air laut Ujung Pancu, air laut Kahju dan air laut Alue Naga. Hasil pengukuran menunjukkan bahwa, nilai arus dan tegangan terbesar didapati pada air laut daerah Ujung Pancu kemudian air laut daerah Kahju dan air laut daerah Alue Naga. Daya hantar listrik yang baik ini menunjukkan adanya korelasi dengan tingkat kadar salinitas air laut daerah tersebut. Dapat disimpulkan bahwa air laut Aceh dapat digunakan sebagai salah satu sumber energi alternatif.

Abstract

A comparative study of metal removal in ferric chloride solution has been completed. The purpose of this study is the effect of acid solution cause material removal of various types of metals such as steel, iron, aluminum and tin. Previously this plate had been prepared by determine the dimensions of the plate size, plate mass and ensuring the plate surface is flat. After that, the plates were immersed in ferric chloride solution with a solution percentage of 27% gram / ml in water for 2 hours. Metal plates had been cleaned and dried and then carried out post-immersion measurements for plate mass, plate dimensions, solution temperature and the acidity of the solution. The result of measurement show the metal plates of steel, iron, aluminum and tin have removed material with a depth of 0.350 mm; 0.550 mm; 0.5625 mm and 0.665 mm. The mass lost after immersion in ferric chloride solution was 2.2 g; 3.9 g; 3.6 g and 7.6 g. Through Faraday's Law, it has been found that the calculation of the material removal rate (MRR) is 0.140 cm3/hour; 0.252 cm3/hour; 0.667 cm3/hour and 0.659 cm3/hour. This has shown the acid solution can remove the metal surface,when the density of the metal is large, material removal rate is low. Therefore, further studies are needed to observe the presence of impurities in the plate and the surface roughness of the metal plate after immersion.

Abstract

Research on the sand iron potential in generating magnetite nanoparticles in Lampanah Aceh Besar through a study of techniques processing, synthesis methods and structural characteristics has been completed. The method used in this research is qualitative method in the kind of literature study from the data of Banda Aceh ESDM Ministry. The results of this study indicate that iron sand in Lampanah area has a dominant element which contained Fe3O4. The magnetic separation method is used to separate the iron sand from impurities, while the co-precipitation synthesis of one of the methods chosen in generating the magnetite nanoparticles which due to a simple, economical experimental process and low treatment temperature. Through the XRD test, the cubic iron sand magnetite nanoparticles with a 2 angle are 35,55o, 57,13o and 62,70o with the hkl [311], [511] and [440], while the TEM and SEM tests showed that the dominant particle shape is round and the distribution is tight. Therefore, controlling the size and shape of iron sand magnetite nanoparticles will provide great potential in the magnetic field of magnetism. The conclusions of this study show that the iron sand located in Aceh Besar has the potential to be a magnetite nanoparticle.
