Abstract

CV. Amna Lab Aromaterapi Small and Medium Enterprises have started the citronella oil business in 2018. Some of its products such as soap, aromatherapy spray, propolis, and body oil have arrived in several big cities in Indonesia. However, since the Covid-19 pandemic, these SMEs have experienced difficulties, especially regarding the large capital costs and the price of citronella which has fallen drastically to 100% of the original price. Under these conditions, SMEs are constrained in the process of increasing productivity and lack production technology as well as marketing and management. The Community Service Team of the ATI Padang Polytechnic offers solutions to overcome these problems by providing alternative processing of citronella oil-based products to be aromatherapy candles and educating the SMEs on the product marketing strategies through e-commerce applications. The community service team tried resolving the delinquent by determining the amount of citronella oil that should be included and the composition variations of stearic acid, vegetable oil, and paraffin. The variations were tested in order to find the right comparison in making aromatherapy candles based on citronella oil. The team also searched and studied several references to analyze marketing strategies in accordance with SMEs CV. Amana Aromatherapy Lab. Considering the result of the experiments, it was identified that 1% of citronella oil could be added to the wax mixture while the exact composition of oil and paraffin was 1: 2. The stearic acid was unsuitable to applied since the candle product easily melted. E-commerce marketing strategies were used by utilizing advertisements on internet searches to expand the promotions.

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

Among various sources of industrial water pollution, effluents from printing, dyeing, and textile processes represent one of the most significant environmental threats. These wastewaters contain numerous toxic and hazardous substances that are difficult to biodegrade. This study investigates the synthesis, characterization, and adsorption performance of a Bentonite–Nano SiO₂ composite for the removal of Rhodamine B dye from aqueous solutions. The research was conducted in two main stages: the preparation of the Bentonite–Nano SiO₂ composite and the evaluation of its adsorption performance at various adsorbent concentrations and contact times. The composite was synthesized by dispersing nano-silica (15% w/w) into bentonite using ethanol as the solvent, followed by stirring, filtration, and drying processes. Characterization using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) confirmed successful modification. Adsorption tests showed that Rhodamine B removal efficiency increased with higher adsorbent concentration, reaching optimal conditions at 0.75% (w/v) with a removal efficiency of 90.2% after a contact time of 10–15 minutes. The enhanced adsorption performance was attributed to the larger surface area, higher porosity, and increased number of active sites resulting from the incorporation of nano-silica
