Batik Jembatan Akar Small and Medium Industry (IKM) endeavors to produce Root Bridge batik fabric, which is a defining feature of the IV Nagari Bayang Utara sub-district. In its production process, IKM Batik Jembatan Akar still relies on rudimentary and traditional equipment and lacks the means to handle textile waste, leading to its disposal in nearby ditches. While the current waste output may not be significant, its continuation poses a threat to the local environment. Insufficient awareness of the environmental impact of textile waste can result in environmental pollution issues and disrupt community harmony around IKM Jembatan Akar. Additionally, IKM Batik Jembatan Akar struggles to stimulate consumer interest in traditional batik amidst the abundance of low-priced printed alternatives. The limited demand for production means that this SME has yet to invest in technology and waste processing equipment for its batik cloth production. Politeknik ATI Padang Community Service initiative seeks to educate all IKM Batik Jembatan Akar employees on the importance of waste processing and online marketing strategies, while providing training on donated textile waste processing equipment to enhance sales value and mitigate environmental harm. The approaches employed in this community service endeavor include (1) comprehensive activity planning, encompassing location surveys, production assessments, and inventory checks; (2) the fabrication and testing of waste processing machinery; (3) educational workshops covering waste management in batik production and its environmental implications, alongside practical training in equipment usage; (4) evaluation of activity outcomes. The outcomes of this Community Service initiative include the provision of textile waste processing equipment and a heightened awareness of environmental conservation, facilitating the integration of waste processing equipment into batik production at IKM Batik Jembatan Akar.

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.

This study aims to produce biodiesel from Refined Bleached Deodorized Palm Oil (RBDPO) using a heterogeneous catalyst based on calcium oxide (CaO) derived from limestone andmodified with palm oil mill fly ash (FA) as a catalyst support. The limestone feedstock was first activated to obtain the CaO catalyst. Subsequently, the FA material was activated through calcination at 500°C. The CaO-FA catalyst was synthesized using the wet impregnation method and then calcined at 600°C. This catalyst was applied in the transesterification of RBDPO with methanol at various molar ratios. The study investigated the effect of different CaO-FA catalyst compositions (1:1, 2:1, and 3:1), and methanol:RBDPO molar ratios (8:1, 10:1, and 12:1) on biodiesel yield. The results demonstrated that both the CaO-FA catalyst ratios and the methanol:RBDPO molar ratios significantly influenced the biodiesel yield and the resulting Fatty Acid Methyl Ester (FAME) composition. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed that the 3:1 CaO-FA composition with an 8:1 methanol:RBDPO molar ratio produced biodiesel with the highest methyl palmitate (C17H34O2) content of 88.99%, which meets the characteristics of high-quality biodiesel. These findings provide valuable insights into the development of CaO-FA-based heterogeneous catalysts for cost-effective and environmentally friendly biodiesel production, in line with government initiatives to promote renewable energy utilization.

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

ABSTRACT. The palm oil industry generates significant waste, including fly ash (FA) from palm oil mill boilers, which poses environmental challenges. This study investigated the potential of FA as an alternative adsorbent for the bleaching of crude palm oil (CPO) and compared its performance with commercial bleaching earth (BE). FA was activated thermally at 400°C and chemically using 1.5 M oxalic acid solution to enhance its adsorption capacity. The results showed that chemically activated FA (FA 1.5 M) and thermally activated FA (FA 400°C) reduced the CPO color from 20 Red (R) to 16-17 R, meeting the industrial standard for degummed bleached palm oil (≤ 17 R). The bleaching efficiency of FA 1.5 M was comparable to that of BE under identical conditions (120 °C and 1.5% w/w adsorbent), demonstrating its practical applicability as an alternative bleaching agent. Characterization results showed that FA 1.5 M had a higher silica (SiO₂) content (77.13%) than FA 400°C (72.46%) and BE (52.01%), along with increased surface area and pore size. FTIR analysis confirmed the adsorption of organic components from CPO onto the activated FA surface, while SEM analysis revealed that chemical activation produced a rougher surface morphology with larger pore diameters. Heavy metal concentrations in both activated FA adsorbents were within safe limits for food applications. Furthermore, BET analysis confirmed that FA 1.5 M exhibited a mesoporous structure with improved adsorption isotherms compared to untreated FA. The study showed that FA particularly FA 1.5 M, shows strong potential as an effective, low-cost, and environmentally sustainable alternative adsorbent in the CPO bleaching process.

Conventional distillation cannot surpass the ethanol-water azeotropic limit (95–96%), necessitating advanced dehydration for fuel grade ethanol (FGE) production per SNI 7390-2012 (≥99.5%). This study designed, fabricated, and evaluated a laboratory-scale ethanol dehydrator prototype featuring a novel 65° inclined horizontal adsorption column filled with 3Å zeolite molecular sieve a configuration not previously reported for ethanol dehydration. Product purity was measured using Gas Chromatography (Shimadzu GC-2010, FID). Under optimal first-run conditions, the system elevated ethanol purity from 96% to 99.79%, successfully meeting the FGE standard. Average vaporizer energy efficiency reached 42.49%, and maximum zeolite adsorption capacity was 0.1277 g water/g zeolite. The 65° inclined column design effectively minimized channeling and outperformed conventional vertical configurations, demonstrating its potential as a practical, low-infrastructure solution for community-scale bioethanol purification.
