Abstract

Bambu masa tanamnya lebih singkat dibandingkan dengan kayu, namun sampai saat ini serat dan pulp bambu belum dimanfaatkan secara optimal sebagai pengganti kayu pada pembuatan komposit oleh industri manufactured wood, misalnya papan serat. Oleh karenanya dilakukan penelitian pembuatan papan serat dengan menggunakan serat dan pulp dari bambu tali (G.apus). Dari hasil uji diketahui bahwa bambu tersebut mengandung alpha selulosa,  hemiselulosa dan lignin, yang merupakan komponen penting dalam serat selulosa, seperti halnya serat dan pulp bambu. Potongan bambu yang dimasak dengan proses soda memiliki panjang serat dan kandungan lignin yang lebih tinggi dibanding serpih bambu hasil pemasakan dengan proses soda dan Kraft. Pembuatan komposit papan serat dilakukan dengan menggunakan matriks resin epoksi, karena epoksi memiliki sifat mekanik yang sangat baik. Kondisi optimal diperoleh dengan menggunakan serat bambu hasil pemasakan potongan bambu dengan proses soda, yang akan menghasilkan komposit dengan kerapatan tinggi. Adapun kandungan air, penyerapan, perubahan panjang dan pengembangan tebal, keteguhan tarik dan lenturnya sesuai dengan standar yang berlaku.

Abstract

An analysis of consumer preferences to find out the characteristics of handicraft paper from betel nut fiber desired is necessary for this innovation. This study aimed to determine the attributes of handicraft paper that are most necessary for consumers. This study was conducted by using Conjoint method. Fifty respondents completed structured questionnaires in some cities in Indonesia. The attribute mix used in this study was physical and organoleptic. The physical attribute mix was tensile strength, grammage, thickness, and stiffness while the organoleptic was color, fiber appearance, and surface texture. There were 16 combinations of stimuli formed with simplification using orthogonal arrays. The result shows consumers like tensile strength of 20-<30 kN/m2, grammage of ≥500 g/m2, thickness of 1,6-3 mm, stiffness of ≥15 mN.m, dark brown color, the appearance of fiber was visible, and had rough surface texture. The results of the correlation analysis showed that there was a strong correlation between the results of preference stimuli and actual responses. The handicraft paper produced had the same characteristics as the consumer preference, except the tensile strength with thevalue ranged from 10-<20 kN/m2. The results also showed that fiber appearance had the highest relative importance value to be prioritized.

Abstract

Oil palm fronds, typically discarded after pruning, have potential as a raw material due to their lignocellulosic content. This study optimizes the soda-anthraquinone pulping process using a circulating digester. It investigates the effects of cooking temperatures (140, 150, and 160°C), cooking times (120, 180, and 240 minutes), and NaOH concentrations (10%, 15%, and 20%) with 0.1% anthraquinone, employing Response Surface Methodology (RSM) based on Central Composite Design (CCD). Analysis with Design Expert 13 software revealed significant impacts on yield (19.01-31.00%), kappa number (9.24-15.69), and viscosity (2.91-34.45 cP). Optimal conditions were 140°C, 120 minutes, and 10% NaOH, yielding 30.57% pulp, kappa number of 13.87, and viscosity of 24.03 cP. This research underscores the environmental benefits of utilizing palm fronds, contributing to waste reduction and circular economy practices, and demonstrates the potential for industrial scalability, offering a sustainable alternative to traditional pulping methods.
