This research purposes to utilize red teakwood charcoal as alternative fuels and then to knows best characters compressive strength, ignition power and caloric value according to Indonesian quality standards (SNI 01-6235-2000). Characteristics of biobriquettes are known by test ash content, moisture content, volatile matter, fix carbon, compressive strength, ignition power and caloric value. The materials used are red teakwood plus industrial flour waste. The process of making biobriquette begins with drying the material, pyrolysis during 150 minutes at a temperature of 400 oC, sieved with 40 mesh. The briquetting was using a cube-shaped mold with manual pressure which was then dried in an oven to a constant weight and tested its characteristics by the ASTM (American standard Testing and material) method. The results showed that the added adhesive was very take effect in producing the best briquettes. The characteristics of briquettes with the best optimum adhesive composition produce is adhesive 5% charcoal 95% produce ash content 5.49% , moisture content 4.26 %, volatile matter 26.89 %, fix carbon 63.12%, compressive strength 3.64 kgf/cm2, caloric value 7038 kcal/kg, and ignition power 0.03 gram/minute categorized as passing the specifications for the quality requirements briquettes of SNI 01-6235-2000.

Abstract

Virgin Coconut Oil (VCO) merupakan minyak nabati yang kaya asam lemak rantai sedang dan senyawa bioaktif, namun rentan mengalami oksidasi lipid selama penyimpanan, khususnya dalam sistem emulsi. Oleh karena itu, penentuan masa simpan emulsi VCO menjadi penting untuk menjamin mutu dan keamanan produk. Penelitian ini bertujuan untuk memprediksi masa simpan emulsi VCO yang diformulasikan dengan emulsifier campuran Tween 80 dan Span 80 berdasarkan perubahan bilangan peroksida sebagai parameter kritis. Prediksi masa simpan dilakukan menggunakan metode Accelerated Shelf Life Testing (ASLT) dengan pendekatan kinetika reaksi dan model Arrhenius. Emulsi VCO disimpan pada tiga suhu penyimpanan, yaitu 30, 45, dan 55 °C. Perubahan bilangan peroksida dianalisis dan dimodelkan menggunakan kinetika reaksi ordo nol, selanjutnya digunakan untuk menghitung konstanta laju reaksi dan energi aktivasi. Hasil penelitian menunjukkan bahwa peningkatan bilangan peroksida mengikuti model kinetika ordo nol dan sesuai dengan model Arrhenius. Masa simpan emulsi VCO, berdasarkan batas kritis bilangan peroksida 3 meq/kg, diprediksi sebesar 89,84 hari pada suhu 30 °C, sebesar 57,54 hari pada 45 °C, dan sebesar 43,73 hari pada 55 °C.

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

Liquid smoke is a product resulting from the pyrolysis of biomass waste that contains chemical compounds with various applications, such as food preservatives, natural pesticides, and raw materials for the chemical industry. Liquid smoke is a by-product of simultaneous pyrolysis. To maximize the yield of liquid smoke while minimizing mass loss that could potentially pollute the environment, the simultaneous pyrolysisreactor needs to operate under optimal condensation conditions. This study observed two condensation parameters: the flow rate and the cooling water temperature of the condenser, using the case study of pyrolysis of biomass waste from coconut trunk sawdust. Pyrolysis was conducted at a temperature of 400°C for 2.5 hours, varying the flow rate of the cooling water in the condenser (1, 2, 2.5, 3, and 3.5 liters/minute)and the temperature of the cooling water (10°C, 20°C, 25°C, and 30°C). A multivariable nonlinear mathematical model was obtained, relating the yield of liquid smoke (y; %) to the water temperature parameter (x1) and the flow rate of the cooling water in the condenser (x2), which is expressed as y = 6.68 + 1.89x1 – 0.04x1² – 0.41x1x2 + 13.06x2 – 0.89x2². It was concluded that the optimal condensation conditions consist of a flow rate and cooling water temperature of 2 liters/minute and 20°C, respectively, yielding a maximum of 36% liquid smoke, 33% charcoal, and a minimum mass loss of 31%. Based on the coefficient values in the obtained mathematical model, it can also be concluded that the more dominant parameter affecting the yield of liquid smoke is the flow rate of the cooling water in the condenser, with a coefficient value of 13.06. An effective condensation system can enhance the conversion efficiency of pyrolysis vapour into liquid smoke and minimize potential pollution, demonstrating significant potential in processing biomass waste into valuable products, such as liquid smoke and charcoal, while being more environmentally friendly and energy-efficient.
