Abstract

The use of palm oil mill fly ash (FA) as a low-cost adsorbent is one of the solutions for handling FA waste. In this study, the addition of dolomite is expected to improve the adsorbent performance. The aim of this study was to investigate the optimum FA-dolomite adsorbent composition and operating conditions for methylene blue adsorption. Different parameters were studied to optimize adsorption process such as the amount of dolomite, methylene blue flow rate, bed height and number of trays. FA-dolomite was converted into nano-adsorbent by sol-gel method which was coated on zeolite surface. Nano-adsorbents were characterized by XRF, FTIR, XRD and SEM. The adsorption capacity was tested by Spectrophotometer UV-Vis. XRF characterization showed that FA had the highest SiO2 content of 58.15%, while dolomite contained CaO of 52.72%. FTIR characterization detected the groups of Si-O-Si, Si-O-Al, Ca-O and Si-O. XRD characterization showed the average crystalline size of FA-dolomite 2% adsorbent was 28.56 nm and SEM characterization showed fine pores on the adsorbent surface. The highest adsorption efficiency obtained at FA-dolomite 2% was 97.364% and the lowest obtained at FA-dolomite 8% was 13.16% with a flow rate of 500 ml/h, adsorbent height of 9 cm and 3 trays. The greater the amount of dolomite added, the absorption efficiency decreases.

Abstract

Most of the residents of Tiku V Jorong Village, Agam District work as farmers and gardeners, whereas the women mostly are housewives. The training given to women community in Tiku V Jorong Village was the production of liquid dish soap. The selection of liquid dish soap products is based on the fact that consumption of dish soap is always needed by every household in their daily life. In addition, the process of making liquid dish soap is relatively easy and the process does not require many equipment, thus it can be done by women community in Tiku V Jorong Village on the sidelines of other daily activities.The liquid dish soap can be used for their daily needs or can be business opportunities for the village. The activity was carried out on November 26, 2022, which was attended by ± 25 women. The training began with the explanation about the materials and equipment used in making the liquid dish soap.  The main materials used were texapon, sodium sulfate, and sodium chloride. Foam booster, perfume, and dye were used as additive. Then, the practice is carried out jointly between the women community and the community service team from Politeknik ATI Padang, thus the women community can be able to make the liquid dish soap on their own. The training was closed with the presentation of business prospective from liquid dish soap. All of the participants were enthusiastic with this training. With this training, it can be expected that the women community in Tiku V Jorong Village have the knowledge and the skill to make their own liquid dish soap. Besides, it can be the new opportunity for business thus the local economy can be improved as well.

Abstract

Penggunaan fly ash (FA) pabrik kelapa sawit (PKS) sebagai adsorben dapat meningkatkan nilai guna dalam pengolahan limbah padat PKS. Penelitian ini bertujuan mengkaji kemampuan FA sebagai adsorben untuk pemucatan (bleaching) crude palm oil (CPO). Adsorben FA diharapkan dapat mengurangi atau menjadi alternatif pengganti adsorben komersial bleaching earth (BE) di industri refinery minyak sawit. Penelitian diawali dengan proses aktivasi adsorben FA secara kimia (penambahan larutan asam oksalat) dan fisika (pemanasan menggunakan furnace). CPO dilakukan degumming terlebih dahulu menggunakan asam fosfat. Selanjutnya, adsorben hasil aktivasi dan adsorben komersial BE digunakan dalam proses bleaching CPO dengan jumlah adsorben dan suhu bleaching yang divariasikan. CPO hasil bleaching dilakukan uji warna dengan lovibond tintometer untuk menentukan kemampuan penyerapan adsorben. Penurunan warna CPO terendah diperoleh pada adsorben FA dengan aktivasi kimia pada konsentrasi asam oksalat 1,5 M (FA 1,5 M) dan aktivasi fisika pada suhu 400°C (FA 400°C) masing-masing sebesar 16R/16Y dengan jumlah adsorben 1,5% dan suhu pemucatan 120°C. Berdasarkan hasil uji gum, penggunaan dosis adsorben 1,5% menunjukkan tidak adanya sisa gum pada CPO hasil bleaching. Selain itu juga dikaji kemampuan penyerapan dari kombinasi adsorben FA dan BE dengan rasio yang divariasikan. Penurunan warna CPO terbaik sesuai standar mutu industri refinery sebesar 17R/17Y diperoleh pada rasio adsorben BE:FA sebesar 1:3 (adsorben campuran BE:FA 1,5 M dan BE:FA 400°C). Kadar FFA CPO hasil bleaching secara keseluruhan mengalami kenaikan dibanding dengan CPO awal yaitu sebesar 7,719%.
