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

PT X Padang is one of the factories that processes CPO (Crude Palm Oil) into Olein commonly called cooking oil. The process of making olein is done through several stages of the process such as degumming, bleaching, filtration, deodorization and fractionation. The purpose of the analysis carried out is to analyze how much the quality deviation of RBDPO is Free Fatty Acid (FFA), color and Iodin Value by using the mean chart control chart (X) and control chart range (R), identifying the causes of quality problems (deviations) RBDPO with a causal diagram (fishbone), provides improvement proposals to improve the quality of RBDPO that occurred at PT. X Padang. The results of processing are the number of samples outside the control limit for FFA levels of 6 samples with a percentage of 37.5%, color that is 10 samples with a percentage of 62.5%, and Iodin Value which is 0 samples. The most dominant causes when viewed with fishbone diagrams are human, machine and material factors. From the results of the analysis it can be concluded that RBDPO products at PT X still have data that is beyond the control limits. The main causes are influenced by human, machine and material factors, so prevention must be done by examining the problems that occur and taking corrective actions.

Abstract

Crude Palm Oil (CPO) is obtained from the extraction process from palm fruit pulp. The extraction process is carried out at the press station. The working principle at the press station is to press the palm raw material in a hollow tube with a rotating screw so that oil will come out through the holes of the tube. The amount of pressure this tool can be adjusted electrically and depends on the volume of material being pressed. This tool consists of a cylinder with a hole in the inside there is a rotating screw. Press pressure is regulated by two cones (conus) located at both ends of the press, which can be driven back and forth hydraulically. Hydraulic pressure at 50-70 kg / cm3 commulator results in wet pulp, resulting in oil losses. The purpose of this study was to determine whether oil losses occurred at the press station in producing crude palm oil (CPO) at PT Perkebunan Nusantara III PKS Rambutan in Tebing Tinggi, North Sumatra by using the Statistical Process Control method. From the research, it is known that from the results of statistical process control (SPC) analysis, it is known that the level of achievement of standards expected by the company has not been achieved on fiber pulp. Where the results of the examination on the fiber pulp sample there are still quality factors that are outside the quality requirements or deviations occur. From the results obtained, it is necessary to propose improvements in performance, both from the quality of humans, machinery and raw materials for CPO processing.

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

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.

Abstract

Biobriquette quality is strongly determined by the drying process, yet the relationship between drying conditions, product quality, and the underlying convective heat transfer mechanism is rarely quantified together. This study evaluates the drying kinetics, product quality, and convective heat transfer characteristics of coconut-shell biobriquettes dried using a dual-blower tray dryer with IoT-based temperature control. Biobriquettes were dried at temperatures of 75-105 °C and durations of 60-150 minutes, and the results were compared with sun drying and with the Indonesian National Standard (SNI 01-6235-2000). The lowest moisture content, 3.81 ± 0.37%, was obtained at 105 °C for 120 minutes, meeting the SNI requirement (maximum 8%), while extending the drying time to 150 minutes caused surface cracking from excessive internal stress. The tray dryer reduced moisture content roughly eight times more than sun drying (3.81% vs. 30.29%) and achieved a drying rate about 4.5 times higher (0.000780 vs. 0.000171 g.cm-2·min-1); these differences, together with the effect of drying temperature and time, were statistically significant (p < 0.05; independent-samples t-test for the tray-dryer-vs-sun-drying comparison and one-way ANOVA with Tukey’s HSD post-hoc test for the temperature and time comparisons). The mean ash content (8.66 ± 0.09%, n = 2) remained slightly above the SNI threshold, indicating room for improvement in carbonization or binder formulation. Convective heat transfer analysis showed a turbulent airflow regime (Re = 660,158.76) with a heat transfer coefficient of 41.01 W.m-2·K-1, higher than a comparable tray-dryer study (25.47 W.m-2·K-1), consistent with forced convection being an important contributor to the observed moisture removal and product quality; as no direct comparison with a single-blower configuration was performed within this study, this interpretation is based on comparison with values reported elsewhere in the literature rather than a controlled experimental comparison.
