Recycle aluminium has been mixed with palm oil fly ash based on fraction weight of overall weight of palm oil fly ashes to aluminium recycle. The ratios discussed on this paper are 0%, 3% 6%, 9%, 12% and 15%. The samples have been developed via sand casting method. The result shows that the best composition has been achieved when we added 3% of palm oil fly ashes, with the new composite aluminum have a highest hardness with the value of 119.7HV, with the Modulus of raptured of 7.71Mkg/m2

Abstract The efficient use of organic fertilisers as a source of nutrient has been a concern in the world oilpalm production. The large amount of Palm Oil Mill Sludge (POMS) and Fly Ash (FA) produced in palm oil industries can effectively be utilized as organic fertilizers and so minimize the amount of waste dispose to the environment. This study is aimed at optimizing the nutrient parameters influencing oil palm seedling growth in soil amended with FA and POMS. The nutrient parameters were optimized using Response Surface Methodology (RSM). The optimization results showed that an increase in the mass of FA and a decrease in the mass of POMS result in a decrease in the growth response of the oil palm seedlings. The responses were best with increase in the mass of POMS and a decrease in the mass of FA. Therefore an indirect relationship exists between the masses of FA and POMS. An empirical quadratic polynomial model was developed to relate the interaction of the POMS and FA. The strong linear correlation between the observed and predicted responses showed that the model reasonably predicted the process using a quadratic polynomial. The maximum plant height of 70.4 cm at 15 % soil amendment was obtained at a mass of 1.46 kg FA and 8.54 kg POMS for the 180 days planting period. Results from this study showed that co application of FA and POMS can be very effective at a maximum of 14.6 % FA and minimum of 85.4 % POMS by mass.

Abu terbang sawit (POFA) merupakan salah satu limbah padat yang dihasilkan dari pembakaran cangkang dan sabut sawit sebagai pembangkit uap untuk konsumsi pabrik sawit. POFA memiliki kandungan silika yang tinggi dan berpotensi digunakan sebagai adsorben. Penghilangan logam pengotor dan pemisahan SiO2 dengan proses ekstraksi merupakan solusi untuk meningkatkan kinerja silika. Proses ektraksi dipengaruhi oleh beberapa faktor diantaranya adalah rasio padat/cair dan waktu pengadukan. Penelitian ini menggunakan rasio padat/cair 1:8, 1:10, 1:12 dan waktu pengadukan 120; 150; 180; dan 210 menit. Hasil penelitian menunjukkan massa endapan silika terbanyak pada rasio 1:12 dan waktu pengadukan 210 menit dengan massa sebanyak 18,35 gram atau 73,4% dari 25 gram POFA dengan kadar silika 47,97% dan luas permukaan silika sebesar 8,18 m2/g. Silika dari setiap variasi diujikan pada air gambut. Efisiensi penyisihan warna, zat organik, dan Fe tertinggi terdapat pada silika hasil ekstraksi dengan rasio padat/cair 1:12 dan waktu pengadukan 210 menit yaitu sebesar 80%, 46%, dan 37%.
