A palm oil company in Dumai carries out a refining process aimed at converting crude palm oil (CPO) into edible oil. The refining process involves several steps, including gum binding (degumming), bleaching with bleaching earth, and the removal of certain components (deodorization). During the process, oil losses often occur, particularly during the bleaching and deodorization stages. The lost oil is typically discarded along with Spent Bleaching Earth (SBE) and Palm Fatty Acid Distillate (PFAD). Therefore, it is necessary to calculate the total oil losses during the refining process and the yield of RBDPO products, as well as to identify the factors that influence the oil losses and RBDPO yield. Analysis shows that the Total Oil losses in the refining process range from 0.12% to 0.22%, and the yield of RBDPO obtained ranges from 94.7% to 95%. Oil losses in Spent Bleaching Earth (SBE) are directly proportional to BE dosing in the bleaching process. Meanwhile, deodorized oil losses are inversely proportional to the purity of PFAD. The yield of RBDPO is influenced by total oil losses and the FFA content of CPO as raw material. The total oil losses and the FFA content of CPO as raw material are inversely proportional to the RBDPO yield.

CPO is a crude oil obtained by extracting the palm fruit’s skin. CPO still contains both soluble and insoluble impurities in the oil. The purpose of palm oil purification is to efficiently convert crude palm oil into high-quality edible oil by removing undesirable impurities to an acceptable level. This also means that the loss of desirable components should be minimized. The refining process, which transforms crude palm oil (CPO) into edible oil, includes degumming, bleaching, and filtering to remove gum and unwanted components. In the Niagara filter, oil losses often occur, where the lost oil is usually discarded with SBE (Spent Bleaching earth). The extent of oil losses also affects the yield of RBDPO. Therefore, it is necessary to analyze total oil losses in the Niagara Filter process and identify the factors influencing these losses. The analysis results show that oil losses in SBE are directly proportional to the dosing of BE (Bleaching earth) in the bleaching process. The highest oil loss value in the Niagara Filter was 0.180%, while the lowest was 0.129% (company standard <0.14%). High oil losses can negatively impact the yield of the produced oil.

CPO (Crude Palm Oil) is yellow-colored crude palm oil derived from the extraction or forging of palm fruit flesh. Factors that determine the quality of CPO production are the levels of free fatty acids, moisture content, levels of impurities. The purpose of the analysis is to analyze how big the deviation of quality of CPO that is free fatty acid content, water content and dirt level by using control chart chart mean (X) and control chart range (R), identify the cause of problem (deviation) of quality of CPO with a causal diagram (fishbone), and provide suggestions for improvement to improve the quality of CPO that occurred. Results obtained from 28 samples were the number of samples outside the control limit for ALB levels of 12 samples with percentage of 43%, water content of 10 samples with percentage 36%, and dirt level that is 6 samples with percentage 21%. The most influential cause when viewed with the fishbone diagram of raw material, machinery and human factors. From the analysis results can be concluded that the quality of CPO production PT X produced there is still data outside the control limit. The quality of CPO produced is influenced by raw material, human and machine factors.

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.

Several MSMEs in Padang Panjang City are engaged in livestock and processed meat and poultry products. These MSMEs can still be said to be small businesses because they implement a pre-order (PO) system for marketing, the variety of products offered is quite diverse, but limited knowledge about quality meat processing and market demands related to food products that comply with halal principles, and effective marketing strategies are not yet well understood as seen from the product packaging which still looks simple. The purpose of this community service activity is for MSMEs to be able to develop and improve product quality, increase competitiveness in the market, and contribute to local economic growth. The ATI Padang Polytechnic Team provided assistance including the introduction of meat processing techniques to create new product variations such as good and halal sausages, selection of quality raw materials, and the right marketing strategies to increase product competitiveness. The activity was carried out on August 20, 2024. The results of the Community Service activities were shown from the questionnaire given to participants. It is known that MSMEs in Padang Panjang city have been able to understand about natural and artificial food additives, healthy and halal meat processing processes, halal certification, shelf life of processed meat products and effective marketing methods.

Penelitian ini bertujuan untuk merancang, membangun, dan menguji kinerja fermentor berbahan akrilik yang diintegrasikan dengan sistem sirkulasi pompa peristaltik untuk produksi bioetanol dari molase. Fermentor berkapasitas 7 liter dirancang menggunakan material akrilik yang transparan dan mudah difabrikasi. Sistem sirkulasi pompa peristaltik diterapkan untuk menjaga homogenitas substrat, distribusi nutrisi, dan stabilitas suhu selama proses fermentasi berlangsung. Penelitian dilakukan dengan membandingkan dua kondisi operasi, yaitu fermentasi menggunakan sirkulasi dan tanpa sirkulasi, dengan memanfaatkan ragi Saccharomyces cerevisiae. Parameter yang diamati meliputi suhu, pH, penurunan nilai Brix (kadar gula), dan densitas selama fermenasi 5 hari. Hasil penelitian menunjukkan bahwa sistem sirkulasi berhasil mempertahankan suhu yang lebih stabil pada kisaran 30–31°C serta pH yang konstan. Fermentasi dengan sirkulasi juga mempercepat fase eksponensial pertumbuhan ragi, meskipun durasinya lebih singkat akibat konsumsi gula yang lebih cepat. Penurunan nilai Brix pada sistem bersirkulasi lebih signifikan, yang mengindikasikan efisiensi konversi substrat yang lebih baik. Disimpulkan bahwa fermentor akrilik dengan sistem sirkulasi pompa peristaltik efektif dalam meningkatkan homogenitas dan stabilitas kondisi fermentasi. Untuk pengembangan selanjutnya, diperlukan penambahan sistem kontrol otomatis dan optimasi kecepatan sirkulasi guna memaksimalkan produktivitas bioethanol.

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.
