In this study the use of a treated palm oil fuel ash (POFA) as a substitute material in producing an improved porcelain ceramic has been presented. The POFA was grounded in a ball mill until the median particle size was reduced to about 50 μm. The POFA was heated at a temperature of 600 oC for 1.5 h in an electric furnace. It was used to substitute quartz in porcelain body from 0 wt% to 25 wt%. The mixed powder was pressed into pellets at pressure of 31 MPa, 61 MPa, 91 MPa and 121 MPa. All the pellets were sintered at a temperature of 1100 oC for 2 h soaking time. It was found out among other things that the bending strength of the samples increases with increase in substitution and also with the increase in mould presure. With a value of 45 MPa the bending strength of the samples containing 15 wt% sintered at a temperature of 1100 oC were higher than the standard porcelain. This could be attributed to compaction and sharp microstructural changes.

Palm oil fuel ash (POFA) is a by-product from agricultural waste produced thousand tonnes every year. This paper presents the use of treated POFA as a substitute material for quartz in fabricating an improved porcelain ceramic. Untreated POFA was dried in an oven at 100 oC for 24 h. Then, it was ground in a ball mill for 1.5 h with the revolution rate of 200 rev/min to reduce the particle size. Next, it was sieved to remove the particles coarser than 50 μm. The POFA was treated by heating it at a temperature of 600 oC for 1.5 h. The mixed powder was then pressed into pellets at mould pressure of 31 MPa, 61 MPa, 91 MPa and 121 MPa. All the pellets were sintered at the temperature of 1100 oC for 2 h soaking time. It was found that the highest compressive strength of 34 MPa is at 15 wt% POFA and mould pressure of 91 MPa. The increment in the strength could be attributed from the changes in the microstructural features as a result of an optimum applied pressure.

The increasing amount of disposed palm oil fuel ash (POFA) from palm oil industries has recently attracted significant attention for an alternative sustainable application. This paper presents the effects of the addition of a treated POFA on porcelain in terms of bending and compressive strength, as well as weight composition. POFA obtained from a palm oil mill was treated via sieving, grinding and heating at a temperature of 600°C for 90 minutes in order to the remove unburnt carbon and to improve the silica content of the POFA. Pellets made with various proportions of porcelain and POFA were fabricated and sintered at a temperature of 1200°C. The results reveal that the maximum bending strength and the compressive strength occurred at 8 wt% addition of POFA, Porcelain containing POFA has about 7% weight reduction compared with normal porcelain.

The treated palm oil fuel ash (POFA) is used as a substitute material in producing an improved porcelain ceramics. Most of the POFA is posed as waste in landfills, causing environmental and other problems. The POFA is grounded in a ball mill until the particle size is reduced to about 50 μm. Then it is heated at a temperature of 600 oC for 1.5 h in an electric furnace. About 5 wt% to 25 wt% of POFA is used to substitute quartz in porcelain composition. The mixed powder is then pressed into pellets at pressure of 91 MPa. All the pellets are sintered at a temperature of 1000 oC, 1100 oC, 1200 oC and 1280 oC for 2.0 h soaking times. It is found that the highest compressive strength, 45 MPa is obtained at 15 wt% of POFA and sintered at 1100 oC. The improvement in the properties could be attributed to the changes in the microstructural features as a result of an increase in mullite and cristobalite simultaneously.

Research of  the utilization solid waste of palm oil fuel ash from boiler as row materials  for manufacturing light concrete brick has been conducted. The main objective of this study is to investigate the potential use solid waste of palm oil fuel ash from palm oil mill boilers as row materials for manufacturing light concrete brick has recently attracted for an alternative environmentally sustainable application. In this study, light concrete brick made with various proportions of palm oil fuel ash from palm oil mill boilers and sand were fabricated and studied under laboratory scales. Percentage of palm oil fuel ash of 0% as a control,  10%, 20%, 30%, 40%, 50%, 60%, replacement  sand, wheras others materials such as Portland cement, lime, gypsum, foaming agent and aluminium with the numbers constant. The quality of light concreate brick   were applied followed by the compressive strength test, density and water absorption capacity. The study discovered that the compressive strength for all composition meet the recommended value to light structural of 6.89 MPa as prescribed in SNI 03-3449-2002. In the same manner density of light concrete brick for all proportion under the maximum density recommended value of 1400 Kg/m3 according to SNI 03-3449-2002. While water absorption capacity of increased by the increasing use of ashes. Therefore, palm oil fuel ash from boiler can be used as raw material for the light concrete brick which is  environmental friendly because using solid waste and also an alternative handling solid waste.ABSTRAKPenelitian pemanfaatan limbah padat abu cangkang dan serat kelapa sawit dari boiler sebagai bahan baku pembuatan bata beton ringan telah dilakukan. Tujuan dari penelitian ini adalah pemanfaatan limbah padat abu boiler berbahan bakar cangkang dan serat sebagai bahan pembuatan bata beton ringan sebagai salah satu alternatif pengelolaan lingkungan yang bekelanjutan. Dalam penelitian ini, bata beton ringan dibuat dengan berbagai komposisi abu boiler dan pasir yang diproduksi dalam  skala laboratorium. Persentase dari abu berturut-turut 0% sebagai kontrol, 10%, 20%, 30%, 40%, 50% dan 60% mensubtitusi pasir, sedangkan bahan lain yaitu semen, kapur, gypsum,  foaming  agent serta aluminium pasta dengan jumlah tetap. Mutu bata beton ringan yang diujikan adalah kuat tekan, bobot jenis dan daya serap air. Hasil penelitian menunjukkan bahwa kuat tekan untuk semua komposisi memenuhi batas minimum yang dipersyaratkan untuk stuktural ringan yaitu 6,89 MPa sesuai SNI 03-3449-2002. Demikian pula bobot jenis dari bata ringan yang dihasilkan masih dibawah dari batas maksimum yang direkomendasikan SNI 03-3449-2002 yaitu maksimal 1400 Kg/m3. Sedangkan daya serap air mengalami kenaikan dengan naiknya jumlah abu yang digunakan . Limbah padat abu boiler berbahan bakar cangkang dan serat sawit dapat dimanfaatkan sebagai bahan baku pembuatan bata beton ringan yang ramah lingkungan dengan memanfaatkan limbah dan menjadi salah satu alternatif pengelolaan limbah. Kata kunci :  Abu cangkang kelapa sawit,  bata beton ringan, bobot jenis,  daya serap air,  limbah,  kuat tekan
