Land Component

Soil is a complex system that is composed of four components, namely minerals, organic matter, air and water. Mineralized material contained in a variety of shapes and sizes, consisting of fragments of rocks, minerals and various compounds result of weathering of rocks. The organic material consists of the remains of plants, animals and micro and macro bodies that live in ...

Fraction Sand and Dust

Sand fraction dominated by mineral quartz (SiO2) which is highly resistant to weathering processes, while the fraction of the dust is usually derived from mineral feldspar and mica are quickly obsolete, and at the time of weathering would release a number of nutrients, so textured soil dust are generally more fertile than soils sand. From this description shows that the ...

Soil Texture

The soil texture is one of the physical properties of soil sifta a very big influence on the growth of plants and other soil properties. Overall the physical properties of the soil is determined by:  The size and composition of the particles making up ground the result of weathering material;  The type and ratio of the composition of ...

Pertukaran Ion Filter Kimia

Pertukaran ion merupakan suatu proses dimana ion-ion yang terjerap pada suatu permukaan media filter ditukar dengan ion-ion lain yang berada dalam air. Proses ini dimungkinkan melalui suatu fenomena tarik menarik antara permukaan media bermuatan dengan molekul-molekul bersifat polar. Apabila suatu molekul bermuatan menyentuh suatu permukaan yang memiliki muatan berlawanan maka molekul tersebut akan terikat secara kimiawi pada permukaan tersebut. Pada ...

Mekanisme Kerja Filter "Under Gravel"

Sesuai dengan namanya filter “under gravel” adalah sebuah filter yang terletak dibawah lapisan “gravel” (kerikil, pasir) di dasar akuarium. Konstruksinya terdiri dari lapisan bahan anti karat (plastik) berlubang dengan kaki penopang sehingga tercipta ruangan bebas dibawahnya untuk memungkinkan air bersih mengalir (Gambar 5). Disalah satu sudutnya (atau lebih) terdapat pipa keluaran untuk mengembalikan air hasil filtrasi kedalam akuarium. Gambar 5. ...
