Abstract

Umumnya, bawang bombai (Allium cepa L.) diekstraksi sebagai bahan penyedap masakan dan obat-obatan. Akan tetapi, proses ekstraksi masih terbatas pada yield yang dihasilkan dengan metode tradisional. Pada penelitian ini digunakan metode ekstraksi microwave hydro-diffusion and gravity (MHG) untuk mengevaluasi bagaimana mempengaruhi yield minyak yang dihasilkan dari bawang bombai. Selain itu, adanya metode sokletasi sebagai teknik ekstraksi konvensional sebagai pembanding terhadap kinerja dan kuantitas ekstrak. Selanjutnya, metode ekstraksi MHG tidak memerlukan penggunaan pelarut, melainkan menggunakan air yang terdapat di dalam material sebagai pelarut internal. Dalam penelitian ini, bawang bombai diperlakukan dengan dua (2) cara yaitu dengan penjemuran sinar matahari (sun dying) selama 1 hari dan tanpa pretreatment. Parameter ekstraksi dengan MHG digunakan daya microwave sebesar 600 W, waktu ekstraksi 75 menit, dan ukuran material 1 cm. Hasil penelitian menunjukkan yield lebih tinggi diperoleh dari bahan melalui sun drying sebesar 2,78% dibandingkan dengan bahan yang tidak di pretreatment yaitu 1,76%. Hasil recovery minyak yang dihasilkan dari metode soxhlet sebesar 4,98% selama 5 jam. Oleh karena itu, metode MHG dapat dijadikan sebagai salah satu metode ekstraksi yang ramah lingkungan, waktu ekstraksi lebih cepat, dan konsumsi energi yang lebih sedikit sehingga dapat diterapkan pada skala yang lebih besar.

Abstract

Darul Iman is an Islamic boarding school located in Tanjung Sari Village, Natar District, South Lampung, which is the area around the Rejosari coconut factory. The coconut factory produces waste, one of which is coconut fibre. Coconut fibre can be reused and has a big opportunity to improve the surrounding community's economy, who generally work as farmers and casual daily workers at the factory. This community service activity aims to provide technical knowledge and skills to students in utilising coconut waste into environmentally friendly recycled products to be distributed back to the surrounding community or implemented themselves. The method used in this PkM activity consists of several stages, namely education on processing waste into coco fibre and how to make the product, then continued with technical guidance on making environmentally friendly recyclable products in the form of doormats and brooms. The effectiveness of PKM activities is evaluated by carrying out a pretest and posttest. The evaluation results show that the average posttest percentage score is 90%, getting a score of more than 70, this indicates that there has been an increase in technical knowledge and skills related to making environmentally friendly recyclable products from coconut fibre waste among the Darul Iman Islamic Boarding School students.

Abstract

Indonesia is the largest producer of palm oil in the world. The palm oil industry always produces solid waste, one of which is palm fiber. Palm fiber can be processed into chemicals or renewable fuels. Catalytic pyrolysis is a pyrolysis process using a catalyst, the purpose of pyrolysis using a catalyst is to upgrade the product. In this study, the pyrolysis process was carried out in a batch reactor with controlled temperature. Catalytic pyrolysis was carried out at a temperature of 400oC with a catalyst to oil palm fiber ratio of 1:2. The control system uses a feedback controller system. Pyrolysis of palm fiber with Al white and NiCl (II) catalysts produces bio-oil products with the highest yield. Pyrolysis with Al2O3 catalyst produces higher Bio-char products. The density of the water phase bio-oil is close to the density of water, and the viscosity of the bio-oil with the oil phase is more than 10 Cp. Based on GC-MS analysis, the largest component in bio-oil is acetic acid. Bio-oil and Bio-char pyrolysis products have the potential as new chemicals, renewable energy and adsorbents.

Abstract

This research focuses on optimizing patchouli oil yield using the hydrodistillation method and adding MgCl2 as the main component. The RSM method is used to analyze model variance, including the sum of squares model, less of the fit model, and ANOVA analysis. The research results show that adding MgCl2 can increase the yield of patchouli oil by reducing water content and undesirable non-volatile elements, thereby producing more stable patchouli oil. ANOVA analysis of patchouli oil yield was carried out to determine the optimal results from factors such as F/S, material size, and time. The extraction time factor had a p-value of less than 0.05, indicating that the model was suitable for explaining the results. The research results showed that the yield of patchouli oil was optimal with an F/S ratio of 0.075, material size of 20 mesh, and extraction time of 5 hours, with a yield of 0.1 gr/mL being the best choice. The research results showed that the use of specific methods, namely distilled water and MgCl2 in the extraction process, was effective in increasing the yield of patchouli oil

Abstract

The low-rank coal is increasing every year but still slightly exploited by the industry, due to it being caused by the low-calorie value of the low-rank coal waste. Therefore, the mixture of other biomass is expected to raise the calorie value. This approach could potentially make the low-rank coal more economically viable for use in various industries, especially as a source of energy. Additionally, further research and development in this area could lead to more efficient and sustainable energy production methods. The study uses the Central Composite Design with ratio of low-rank coal waste and palm kernel shells of 40%: 60%, 60%: 40%, and 80%: 20% and variations of the glue starch (5 to 7%), which have been optimized and validated using the Response Surface Method approach. The results of the study showed volatile matter, fixed carbon, and calorie values of 61.43% to 71.69%, 16.56% to 26.98%, and 5190.44 to 6330.40 kcal/g, respectively. The results also demonstrated that the glue with 6% variation showed the highest fixed carbon content and calorie value in comparison to the other variations. The optimum of concentration of low-rank coal and palm kernel shell for co-firing of 80: 20% with 5% glue addition resulting in a volatile matter, fixed carbon, calorie value, flame capacity, flammability, of 54.41%, 33.39%, 6192.123 kcal/g, 14.12 min, and 0.052 g/min, respectively. The validation process also met the requirements for SNI 01-6235-2000 and SNI 8675-2018. Overall, the study concluded that the co-firing of low-rank coal waste and palm kernel shell with glue starch can result in an optimized fuel mixture with high performance characteristics. These findings are significant for industries looking to improve their energy efficiency and reduce emissions.

Abstract

Biosurfactants are natural surfactants produced by certain microorganisms (bacteria, fungi, and yeast) and are considered the best candidates for replacing synthetic surfactants. Bacteria isolated from oil spill areas have shown the ability to produce biosurfactants. This study enriched bacteria from anaerobic wastewater of palm oil industry in Lampung then isolated and screened natural surfactant-producing bacteria and measured their emulsification activity. Screening of surfactant-producing bacteria was carried out using oil spreading assay and their emulsification activity was measured based on the emulsification index (EI). The results of the study obtained 7 bacterial isolates and all showed positive results in the oil spreading assay. The highest emulsification index (EI) was produced by the fifth isolate (LAC5) with a value of 42.32%. These results show the potential for emulsification activity of biosurfactants produced by anaerobic wastewater bacteria from palm oil industry ponds.
