Sampah Rumah Tangga di Ternate

Abstrak Jumlah penduduk Kota Ternate 212.997 jiwa, luas wilayah 111,39 km2 dengan kepadatan 1.865,42 jiwa/ km2. Apabila kita menggunaan pendekatan paradigma “sampah sebagai barang berguna” maka jumlah penduduk sebanyak itu menghasilkan volume sampah yang berpotensi untuk dimanfaatkan dan diolah kembali. Terkait kepentingan pengelolaan dan pemanfaatan sampah di Kota Ternate ke depan, maka kedudukan sampah merupakan sebuah potensi. Deskripsi potensi sampah harus diawali dengan pengenalan komposisi dan timbulan sampah yang ada, terutama sampah rumah tangga. Gambaran komposisi akan memberikan informasi tentang komponen yang terdapat dalam buangan padat beserta distribusinya. Timbulan sampah memberikan informasi banyaknya sampah rumah tangga yang dihasilkan. Data timbulan sampah juga diperlukan untuk desain sistem pengelolaan persampahan, seleksi jenis peralatan untuk transportasi sampah dan desain tempat pembuangan sampah. Kata Kunci:, komposisi sampah, rumah tangga, Kota Ternate Abstract The population of Ternate City is 212,997 people, the area of 111.39 km2 with the density of 1,865.42 people/km2. If we use the paradigm approach of "waste as a useful item" then the amount of population as much as it produces the volume of waste that has the potential to be utilized and reprocessed. Related to the management and utilization of waste in Ternate City in the future, the position of waste is a potential. Description of potential waste should be started with the introduction of composition and waste generation, especially household waste. The composition description will provide information on the components contained in solid waste and its distribution. Waste generation provides information on the amount of household waste generated. Waste generation data is also required for the design of waste management systems, the selection of equipment types for waste transport and the design of landfills.

Modeling of Wave Propagation in the ADINA Software for Simple Elastic Structures

The paper presents the waves propagation (disturbances) in the simple elastic structures aided by ADINA program. Modeling of the waves was performed in a rod and the elastic layer. The elastic structures being analyzed have been made of isotropic compressible and incompressible materials which represent hyperelastic materials, i.e. with a strictly defined elastic potential description. Conclusions are presented in the summary at the end of the study.
