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

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%.

Abstract

The understanding and compliance with the regulations of the Drug and Food Supervisory Authority (BPOM) in the food industry, especially for Micro, Small and Medium Enterprises (MSMEs) in Indonesia should be a concern for entrepreneurs so that the products produced are acceptable to modern society today. The packaging process is one of the efforts to maintain the quality, safety and hygiene of products, also as a medium of promotion and information of products marketed to consumers. MSMEs Kampioen becomes an object in the community service activities carried out by the Team of Polytechnic ATI Padang due to the eligibility of partners and business permits that already meet the existing legality. Observations and interviews were conducted to find out the obstacles experienced by MSMEs. The obstacles facing MSMEs are products that have not yet been able to compete to the supermarket because the unqualified packaging of supermarkets and BPOM. The packaging machines used are old enough and almost broken. In this context, the graphical design of packaging that meets BPOM standards and the use of Continuous Band Sealer technology is an important factor in improving competitiveness and market access for MSME. These activities ensure the benefits of accompanying activities, such as improved efficiency and production safety, improved understanding of business management, finance, and marketing, and expansion of marketing. Thus, these activities provide practical guidance and specific solutions to help MSMEs boost growth and competitiveness in the food industry sector.
