چکیده

Proses pengolahan minyak di Indonesia sangat menguntungkan untuk perekonomian negara. Tetapi disamping itu, terdapat hal yang meyebabkan kerugian yaitu terjadinya tumpahan minyak. Tumpahan bisa diatasi salah satunya dengan menggunakan absorben. Silika aerogel dapat digunakan sebagai Bahan baku utama sintesis silika adalah silika. Pada pasir laut rata-rata mengandung cukup tinggi sebesar 70%. Penelitian ini dilakukan mengetahui pengaruh precursor dalam modifikasi material bersifat oliofilik dan hidrofobik. Pembuatan terbagi menjadi beberapa bagian pembuatan waterglass (sodium metasilikat) dari laut, kemudian waterglass. Dalam metode variabel pembanding penambahan TEOS (tetraetil ortosilikat) heksana perbandingan volume 1:1, 1:2, 1:3 sedangkan etanol divariabelkan konsentrasi volumenya rincian 10%, 20%, 30%. produk karakterisasi bertujuan sifat-sifatnya. diuji XRF (X-Ray Fluorescence) komponen terkandung hasil SiO2 98,9%, K2O 1,2%, CaO 0,6%, TiO2 0,766%, V2O5 0,007%, MnO 0,028%, Fe2O3 0,431%, NiO 0,01%, CuO 0,035%, Yb2O3 0,03%. Sedangkan uji sudut kontak serapan minyak, didapat pada sampel dua sebanyak 1:2 20% memiliki 143,95o kemampuan menyerap 13,98 g/g aerogel.
 Oil processing in is very profitable for the economy of country. However, exploration process there might be an oil spill which can cause a loss production. overcome by using absorbent. Silica used as The main raw silica absorbent silica. Sea sand contains high enough reaches 70% on average. This research was conducted to determine effect precursors modification oliophilic and hydrophobic. synthesys divided into several parts, namely from sea In this method, variables were with addition (tetraethyl orthosilicate) hexane ratio 1:3, while ethanol varied concentration product characterized order their properties. method 98.9%, 1.2%, 0.6%, 0.766%, 0.007%, 0.028%, 0.431%, 0.01%, 0.035%, 0.03%. While characterixed contact angle absorption test. result, sample TEOS:hexane much have 143.95o has ability absorb 13.98 aerogel.

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

An objection to the memetic approach to culture Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson's models (1985, Boyd this volume), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. The memetic approach is based on the claim that culture is made of memes. If one takes...

Many scientists have until recently considered consciousness to be unsuitable for scientific research. As Damasio remarks, ‘studying consciousness was simply not the thing to do before you made tenure, and even after you did it was looked upon with suspicion’ (Damasio, 1999, p. 7). Prompted by technological developments as well as conceptual changes, this attitude has changed within the last de...
