Abstract

Pengembangan kualitas perekat alami untuk industri kayu merupakan hal yang menarik untuk dikaji. Penelitian ini bertujuan untuk meningkatkan kualitas perekat alami berbahan dasar tepung tapioka menggunakan minyak zaitun. Kandungan gugus fenol yang banyak membuat minyak zaitun berpeluang digunakan sebagai bahan aditif untuk perekat. Pembuatan perekat dilakukan dengan metode hidrolisis, oksidasi, polimerisasi dan penambahan minyak zaitun. Pengujian berupa viskositas, kandungan padatan, kuat geser kering dan basah dilakukan untuk mengetahui kualitas perekat. Hasil percobaan menunjukkan bahwa viskositas PA25% mengalami peningkatan dibandingkan dengan viskositas PA0%. Seiring dengan penambahan minyak zaitun, kandungan padatan di dalam perekat dan kuat geser kering mengalami mengalami penurunan. Reaksi polimerisasi antara monomer MMA yang digunakan dengan tepung tapioka serta penambahan minyak zaitun tidak memberikan kekuatan daya rekat yang memuaskan.

Abstract

Wood adhesive has significant contribution in the development of furniture industries. Currently, the most widely used type of adhesives is synthetic adhesive which is carcinogenic to humans. This research aimed to develop cassava starch-based bioadhesive. The additive added to the adhesive was virgin coconut oil (VCO) which had antibacterial and antifungal properties. The research method used is quantitative approach where adhesives were made and the properties were analyzed. The steps of making the adhesives included hydrolysis reaction, oxidation, and VCO addition. The reaction was carried out at 70 ℃ and atmospheric pressure for 90 minutes. The amount of VCO added were varied to 0%, 10%, 15%, 20%, 25%, and 30% of the weight of cassava starch. The properties measured were viscosity, solid content, shelf life, shear strength, and the molecular structure of the adhesives. The results showed that the addition of VCO improved the shelf life of the adhesive but weakened the shear strength of the adhesive. The amount of VCO that should be added to improve the adhesive quality is 10% of the weight of cassava starch.

Abstract

The adhesive that is widely used today is the synthetic one, which is carcinogenic to humans. It is necessary to produce adhesives based on natural resources (bioadhesive) to reduce the use of synthetic adhesive. Gelatin is a compound that has amine groups, while adipic acid is an organic acid that has carboxylic groups in its chemical structure so they can be primary ingredients to make adhesive. The research objective is to reduce the use of synthetic adhesives with best quality of bioadhesive. The steps of making the adhesives included polymerization reaction and hydrolyzed palm oil addition. The polymerization reaction is carried out in batches at 90 ℃ and 1 atm with mole ratio palm oil to gelatin variety of 0; 0.04; 0.08; 0.17; 0.33; 0.5; and 1. The best result for tensile strength is the ratio of 0.33 mole ratio of palm oil to gelatin for 1 day, 3 days, 7 days, and 14 days of curing time, respectively 1575.71 kPa, 2197.30 kPa, 3387.31 kPa, dan 3708.23 kPa.

Abstract

Hydrogen has been recognized as a global sustainable alternative sustainable energy source. The government of Indonesia has been working on a novel idea to launch the hydrogen industry. Accordingly, research and development of ecologically acceptable hydrogen manufacturing methods are essential. Supercritical water gasification (SCWG) is one of the recent techniques to create hydrogen. This research investigated the techno-economics of hydrogen production in Indonesia using SCWG. Oil palm trunks (OPT), a plentiful byproduct of palm oil plants, are the primary raw materials employed in this industry. This study extracted data from several research publications on SCWG-related hydrogen generation and performed computational analysis using several economic parameter equations. According to the analysis, with a potential OPT source of around 34 million tons, the plant could manufacture 304,166.67 tons of OPT per year, generating 365,000 tons of hydrogen annually. The production cost was projected to be USD 1,179,409,295, with a fixed capital investment of USD 1,178,853,030.47. The expected annual income was USD 1,825,000,000. This assessment yielded an ROI of 60% and an NPV of USD 1,888,889,382.70. The IRR value was 26.96%, with a PoT of 2.49 years. The sensitivity analysis revealed that the price of hydrogen significantly affected the values of IRR and PoT. Therefore, the government must determine the exact price of hydrogen to ensure its sustainability.
