    (2016-10-12) Lasmana, Andrik; Mukhtar, Akmal; Tamboesai, Emrizal Mahidin
    The increase in the adsorption capacity of the zeolite can be done by modifying the zeolite. This research aims to use the activated zeolite for adsorption of the dye congo red with some parameters. Preparation of adsorbent begins with the physical activation by heating for 2 hours at a temperature of 3000C. Zeolite was characterized using X-Ray Diffraction (XRD) and Fourier transform infrared (FTIR). Parameters for congo red dye adsorption were analyzed mass, contact time and pH. Adsorptiont process was done by varying the mass (0.1, 0.5, 1 and 1.5 g) , the contact time (30,60,90 and 120 minutes), and pH (1, 3, 5, 7 dan 9) and measured using UV-Vis Spectrofotometri. All adsorption values obtained were compared between natural zeolite activated and non-activation of natural zeolite. The results indicate that activation zeolite better absorption than the non-activation of zeolite. The optimum condition for adsorption was at mass (0.1 g), time (90 minutes) and pH 3 which activated zeolite for adsoption percentage reached 95.49% while the non-activation zeolite adsorption percentage of only 44.65%

    Crude oil is the main energy resources for industry, transportation and house hold needs. The demand for crude oil in Indonesia is much higher than its production which leads to current energy crisis. One of solutions for this crisis is to conduct correlation study, which determines the genetic relationship at each oil well. The correlation study of crude oil between in Bangko Rokan Hilir with Duri Bengkalis has not been conducted previously. This study could assist to provide the indication of the genetic relationship, deposition zone, souce rock and the origins of Bangko and Duri’s crude oil. The crude oil samples taken immediately from oil wells was first refrigerated before conducting geochemistry analysis. The samples were then fractionated by column to separate saturated fraction. This fraction was analyzed using Gas Chromatography (GC). On the basis of the abudance of hydrocarbon aliphatic, the crude oils samples have small ratio value, which is 0,38-0,50 for Pr/n-C17 and 0,16-0,18 Ph/n-C18. This values indicated that the samples were originated from higher vascular plants (terrestrial). The samples derived from lacustrine environments (lake) have ratio value of Pr/Ph (2,50-2,90). The calculation from Star diagram have showed that the samples of production oil field in Bangko (MB-07, MB-026 and MB-172) are positively correlated, but the samples of production oil field in Bangko MB-07 with MB-026 is closer correlation than the MB-172, whereas the oil samples in area MB-07, MB-026 dan MB-172 of Bangko with the oil sample in Duri (MD-01) are negatively correlated. The positive correlation indicated that the samples have the genetic relationship at each oil, a same source matter.

    Mangan oksida sangat menarik untuk diteliti karena memiliki aplikasi yang sangat beragam. Aplikasi mangan oksida sangat erat kaitannya dengan struktur yang dimiliki oleh mangan oksida tersebut. Mineral mangan oksida terdiri atas berbagai struktur yaitu struktur berongga seperti hollandite, todorokite, cryptomelane, pyrolusite dan coronadite;struktur berlapis seperti busserite, birnessite, chalcophanite ,dan lithiophorite; serta struktur amorphous. Mangan oksida dengan bentuk struktur berongga seperti cryptomelane (2x2) dapat dimanfaatkan sebagai katalis, penukar ion, dan adsorben[1]. Mangan oksida berongga lainnya, dengan bentuk struktur rongga yang lebih besar adalah todorrokite. Todorrokite dengan ukuran rongga (3x3) memiliki luas permukan yang relatif besar (hingga 250 m2/g) sangat potensial digunakan sebagai katalis dan odsorben[2]. Mangan oksida dengan rongga paling kecil (1x1) adalah pyrolusite yang banyak digunakan pada industri gelas dan baterai. Mangan oksida dengan bentuk setruktur berlapis seperti birnessite dapat digunakan sebagai material penukar ion, material katoda untuk baterai lithium dan adsorben [3]. Birnesite juga digunakan sebagai prekursor yang digunakan dalam sintesis todorokite [4]. Pemanfaatan birnessite ini sangat ditentukan oleh sifat-sifat permukaan khas yang dimilikinya, seperti luas permukaan, morfologi, dari material birnessite. Namun demikian, salah satu permasalahan yang timbul adalah birnessite sulit ditemui dalam keadaan murni di alam, sehingga perlu analisis sifat permukaan digunakan birnessite yang telah disintesis. Sintesis mangan oksida dapat dilakukan dengan berbagai metoda, pada penelitian sebelumnya dengan menggunakan KMnO4 dan MnSO4 telah disintesis mangan oksida Holondite menggunakan metode hidrotemal [5], dengan metode yang sama prekursor Na-birnesite dan MgCl telah dihasilkan todorike [6]. Birnesite juga telah berhasil disintess dengan menggunaan KOH untuk mempelajari morfologi oleh mangan oksida berlapis dari cotton menjadi had platelike ]7]. Berdasarkan latar belakang di atas maka pada penelitian ini akan dilakukan sintesis dan analisis sifat permukaan mangan oksida –berlapis- dengan mengggunakan prekursor maltosa sebagai reduktor. Analisis terhadap sifat birnessite diamati terhadap karakterisasi, XRD, FTIR, TGA-DTA dan AAS.
