Abstract

Limbah serbuk kayu hasil proses penggergajian ataupun limbah dari penghalusan kayu memilki banyak manfaat bila diproses lebih lanjut. Salah satu yang dapat dilakukan yaitu dengan memanfaatkan limbah serbuk gergaji kayu menjadi asap cair. Penelitian ini dilakukan dengan tujuan untuk mengetahui potensi pemanfaatan limbah biomassa serbuk gergaji kayu besi menjadi asap cair melalui proses pirolisis. Metode penelitian ini dilakukan dengan cara menyiapkan sampel limbah serbuk gergaji kayu besi sebanyak 1000 gram, kemudian dilanjutkan dengan metode pirolisis selama 120 menit dan temperatur pirolisis yang dipertahankan yaitu 400 oC, hasil pirolisis diperoleh tiga produk yaitu asap cair, charcoal dan sedikit tar, asap cair yang dihasilkan kemudian ditimbang dan diukur volumenya, analisa dilakukan dengan metode MC-GS. Hasil penelitian ini menunjukan bahwa secara batch diperoleh kandungan total Phenol 49% area. Kandungan total Benzen sebesar 12% area. Kandungan total asam sebesar 11% area. Yield asap cair sebesar 38%. Dari hasil analisa yang telah dilakukan, tidak ditemukan adanya senyawa benzopyren, yang berarti bahwa asap cair yang dihasilkan bagus digunakan sebagai bahan pengawet pangan.

Abstract

One of the critical challenges in the virgin coconut oil (VCO) industry is the selection of crude VCO filtration media that must be strictly guaranteed halal, since VCO is widely used as a food ingredient and for medicinal purposes. In this study, coconut trunk sawdust waste was utilized as a raw material and converted into charcoal through a pyrolysis process. The resulting charcoal was then applied as a bioadsorbent for crude VCO filtration. This article reports the effect of bioadsorbent particle size variations, specifically -/20, 20/50, 50/100, 100/140, 140/200, and 200/- mesh, to determine the optimum particle size that provides the highest VCO clarity. The experiments were conducted under constant conditions with a bioadsorbent-to-VCO ratio of 2% (g/mL) and a filtration time of 10 minutes. The optimum particle size was obtained at 50/100 mesh (200 µm), which resulted in maximum VCO clarity with a turbidity value of 1.48 NTU. Based on this optimum particle size, the filtered VCO showed desirable quality parameters, including lauric acid content of 51.96%, total suspended solids of 5.77%, density of 0.95 g/mL, total plate count (TPC) <10 CFU/mL, and moisture content of 0.0235%. These characteristics meet both the Indonesian National Standard (SNI) and international standards of the Asian and Pacific Coconut Community (APCC). Moreover, the resulting VCO exhibited better clarity than commercial VCO filtered using paper or cloth media (1.59 NTU), while also ensuring halal integrity through the use of bioadsorbent derived from pyrolyzed coconut trunk sawdust

Abstract

Research has been carried out on the utilization of biomass waste of coconut trunk sawdust using the pyrolysis method to produce two products simultaneously, namely charcoal and liquid smoke. In order to obtain charcoal products with optimum calorific value, it is necessary to understand the optimum pyrolysis conditions. One of the optimum conditions, namely pyrolysis temperature, was studied in this research. Pyrolysis was carried out in a simultaneous pyrolysis reactor at a flow rate of argon inert gas into the reactor of 2 liters/minute and a pyrolysis time of 2.5 hours with pyrolysis temperature variations of 350, 400, 450, and 500°C, respectively. The study showed that the optimum temperature of 400oC was obtained which gave a yield of 34% charcoal with a calorific value of 7229 kcal/kg. Compared to the calorific value of the raw material for coconut sawdust which is 4400 kcal/kg, there was an increase in the calorific value of the pyrolysis product by 64%. Based on the optimum temperature condition, liquid smoke as a by-product was also obtained with a yield of 45%. Charcoal can be used as a solid fuel or as a bioadsorbent in the treatment of liquid waste or clarification of liquid food products such as virgin coconut oil (VCO). Grade 3 liquid smoke can be used as a biopesticide, while grade 1 liquid smoke can be used as a food preservative. Given the benefits of the two pyrolysis products, both of the products from the current research have a promising market value.

Abstract

Virgin Coconut Oil–Orange Juice Emulsion (EVCO-SJ) is formulated by mixing Virgin Coconut Oil with Orange Juice and other additives.  EVCO-SJ was developed as an alternative form of VCO consumption to reduce the oily sensation in the mouth when consuming VCO directly. Determining the product's shelf life is a crucial aspect because it is closely related to determining the expiration date of food products.  This study aims to predict the shelf life of EVCO-SJ based on changes in peroxide value using the Accelerated Shelf-Life Testing (ASLT) method. EVCO-SJ is made by mixing VCO and orange juice (8:2) using gum arabic (0.75%) as emulsifier and homogenized using a Tokebi device at 23,000 rpm for 2 minutes. EVCO-SJ is stored at three temperature variations, namely 30 °C, 45 °C, and 55 °C, with storage time intervals of 0, 7, 14, 21, 28, and 35 days. The observed quality parameter is the peroxide value as an early indicator of lipid oxidation.    Data on changes in peroxide value are analyzed using the Arrhenius model in the ASLT method to predict shelf life. The results showed that increasing storage temperature accelerated the rate of lipid oxidation in EVCO-SJ, as indicated by an increase in the peroxide value during storage. Predicted shelf life of EVCO-SJ based on the ASLT method indicated that the shelf life at 30°C, 45°C, and 55°C was 146.34 days, 83.46 days, and 59.06 days, respectively. These results provide scientific information regarding the oxidative stability of EVCO-SJ and can serve as a basis for determining shelf life and developing VCO-based emulsion products with measurable quality and shelf life
