Abstract

Calophyllum is a potential plant in Indonesia where the area is very wide spread besides almost all parts of Calophyllum plants can be utilized. The study aims to produce alkyd resin from Calophyllum oil so the usefulness of Calophyllum plants can be optimized. The synthesis of alkyd resin was carried out by variations in oil to glycerol mole ratio (1:3, 1:4, and 1:5) and temperature (230 and 250C). Acid and iodine values, density, viscosity, drying time, color, solubility, thermal stability, and functional groups analyzed the alkyd resin quality. The oil-to-glycerol mole ratio and temperature variations affected the acid value, viscosity, color, and drying time. Higher temperatures and more glycerol affected the reaction time, and the drying time of alkyd resin became faster. In addition, its viscosity decreased, and its thermal stability was stable. With the high addition of glycerol at low temperatures, the color of alkyd resin was bright, but it became darkened at higher temperatures. Calophyllum-based resins owned the fastest alkyd resin drying time without passing through the drying and purifying process, which was 60 minutes at 50°C

Abstract

Tamanu oil is rich in active compounds beyond just fatty acids, including calophyllolide, inophyllums, calanolides, tamanolides, and coumarins, all of which offer antioxidant, anti-aging, anti-inflammatory, anti-UV, and anti-bacterial benefits. This makes tamanu oil a promising ingredient for skincare products such as facial oils, soaps, and shampoos. The oil can be produced by mechanical and/or solvent extraction. This research aimed to develop a medium-scale tamanu oil industry and its by-products from Calophyllum fruits, identify suitable production technologies, design a business model using the business model canvas, and conduct a feasibility analysis. The feasibility analysis was carried out by taking into account technical and technological, market and marketing, environmental, management and organizational, and financial aspects. The financial aspect included determining the B/C ratio, payback period, net present value, and return of investment. The production process tested in this study utilized fresh Calophyllum seeds and employed hot screw pressing along with binary solvents for extraction. The outputs from processing 1000 kg of calophyllum fruits included 141 kg of virgin tamanu oil, 57 kg of tamanu oil, 7.05 kg of resin, 594 kg of biopellets, and 142.2 kg of animal feed. The feasibility study indicated a positive net present value, a B/C ratio of 1.53, a payback period of 1.04 years, and a return on investment of 95.31%, confirming that establishing and operating a tamanu oil industry and its byproducts from calophyllum fruits is viable.

Abstract

Bambu muda atau rebung memiliki sumber selulosa dan berpotensi untuk produksi bioetanol. Rebung juga memiliki kandungan lignin yang rendah yaitu 0,89%, sehingga memungkinkan untuk tidak dilakukan proses pre-treatment. Rebung bambu merupakan salah satu bahan yang berpotensi untuk produksi bioetanol mengingat laju produktivitas yang tinggi yaitu 8.124 kg/ha/tahun. Tujuan dari penelitian ini adalah menganalisis data produksi bioetanol dari rebung dengan teknik SSF menggunakan konsorsium mikroba Trichoderma reesei dan Saccharomyces cerevisiae. Mikroba T. reesei digunakan untuk menghasilkan enzim selulase yang menghidrolisis selulosa menjadi gula sederhana, sedangkan S. cerevisiae digunakan untuk memproduksi bioetanol dari gula yang dihasilkan sebelumnya. Sintesis bioetanol terdiri dari dua tahap utama yaitu hidrolisis dan fermentasi. Pada penelitian sebelumnya, proses hidrolisis dan fermentasi dilakukan secara terpisah menggunakan metode SHF (Separated Hydrolysis Fermentation), sedangkan pada penelitian ini dilakukan dengan menggunakan metode SSF (Simultaneous Saccharification and Fermentation) yang diharapkan menghasilkan efisiensi substrat, Yp/s, dan laju produktivitas bioetanol yang lebih tinggi dibandingkan metode SHF. Penelitian ini dilakukan menggunakan aerasi 1 vvm dan agitasi 125 rpm selama 72 jam.  Hasil penelitian menunjukkan bahwa produksi  bioetanol tertinggi di waktu 72  jam sebesar 6,94 g/L dengan laju produktivitas bioetanol  0,08 g/L/h dan  rendemen produk (Yp/s) 0,19 g bioetanol/g substrat. Hasil penelitian ini menunjukkan bahwa rebung merupakan media yang layak untuk produksi bioetanol. Rebung memiliki kandungan selulosa yang potensial sebagai substrat untuk T. reesei dan terbukti menghasilkan bioetanol yang lebih tinggi dibandingkan teknik SHF dengan bambu pada penelitian sebelumnya.
