“…Masyarakat Indonesia pada umumnya menggunakan biji buah pinang dengan mengunyah sebagai salah satu cara untuk menghangatkan badan dan membersihkan gigi, biasanya dikenal dengan istilah menyirih yaitu mengunyah buah piang, daun sirih dan kapur [3]. Buah pinang berbentuk bulat lonjong dengan panjang 3,5 cm -7 cm, dengan warna kuning emas atau jingga untuk buah yang sudah matang dan berwarna hijau untuk buah yang masih muda serta berwarna cokelat untuk buah yang sudah kering/tua [4]. Dinding buahnya berserabut berserat keras meliputi endosperm dan berat kulitnya sekitar 60-80% dari total berat buahnya [5].…”

“…Serat AHF dapat diperoleh melalui teknik pengelupasan kulit buah, dengan cara penghilangan biji buah untuk mendapatkan kulitnya. Komposisi kimia dari serat BNH juga telah dibahas oleh beberapa peneliti [1,4], yang disajikan pada Tabel 1. Para peneliti telah melaporkan bahwa AHF terdiri dari ơ-selulosa, hemiselulosa, lignin, pektin dan protopectin, abu dan bahan lainnya .…”

Makalah ini menganalisis pengaruh perlakukan alkali dan tanpa perlakukan alkali terhadap karakateristik fisik, morfologi dan sifat mekanik serat kulit buah pinang (areca Catechu L.). Selama ini pemanfaatan limbah pertanian belum dilakukan secara maksimal, sehingga dapat menimbulkan pencemaran terhadap lingkungan. Serat kulit buah pinang (Areca Husk Fiber/AHF) selama ini hanya dipergunakan sebagai bahan bakar biomassa dan media tanam sedangkan untuk pemanfaatan lain belum ada sama sekali. AHF diberi perlakukan NaOH 2,5%, 5%, 7,5% dan 10% dengan waktu perendaman 2 jam pada temperatur kamar, untuk mengetahui karakteristik fisik AHF maka dilakukan pengukuran panjang dan diameter serat, pengujian densitas, pengujian kadar air dan moisture sedangkan untuk mengetahui karakteristik mekanik dilakukan pengujian tarik serat tunggal sesuai dengan ASTM D 3379. Dari penelitian ini diketahui bahwa diameter AHF mengalami pengurangan diameter akibat perlakukan alkali, hal ini terkait dengan hilangnya kandungan lignin, pektin dan wax. Densitas AHF menurun dengan meningkatan prosentase NaOH bila dibandingkan dengan AHF tanpa perlakukan NaOH. Kekuatan tarik bervariasi dengan adanya perlakuan alkali. Kekuatan tarik AHF tertinggi pada serat yang mengalami perlakukan NaOH 5% yaitu sebesar 165 Mpa dan kekuatan tarik terendah pada AHF dengan perlakuan Alkali 10% yaitu sebesar 137 MPa . This paper analyzes the effect of alkali and non-alkali treatments on the physical characteristics, morphology and mechanical properties of betel nut huks fiber (areca Catechu L.). the used of agricultural waste has not been done optimally, causing environmental pollution. Areca Husk Fiber (AHF) only used as biomass fuel and planting medium, while for the other uses it has not existed. AHF was given 2.5%, 5%, 7.5% and 10% NaOH treatment with 2 hours immersion at room temperature, to known the physical characteristics of AHF then measured the length and diameter of fiber, density test, water content and moisture test. Mechanical characteristics of single fiber tensile testing in accordance with ASTM D 3379. From this study that known the diameter of AHF has a reduction in diameter due to alkaline treatment, this is related to loss of lignin, pectin and wax content. The density of AHF decreases with the percentage increase of NaOH when compared with AHF without the treatment of NaOH. Tensile strength varies with alkaline treatment. The highest AHF tensile strength in treated fibers was 5% NaOH of 165 Mpa and lowest tensile strength in AHF with 10% Alkali treatment of 137 MPa.

When manufacturing fiber-reinforced composites, it is possible to improve the quality of fiber steel fire and reduce the number of cracks in the finished product if it is possible to quickly identify the defects of the fiber tow. Therefore, in this study, we developed a method to identify the condition of carbon fiber tow using eddy current test (ECT), which is used to improve the quality of composite materials. Using the eddy current detection sensor, we checked the impedance results according to the condition of the CF tow. We found that the materials of the workbench used in the experiment greatly affected the ECT results, so it is necessary to use a material with a non-conductive and smooth surface. We evaluated the impedance results of the carbon fiber at 2 mm intervals using the ECT sensor and summarized the impedance results according to the fiber width direction, presenting the condition of the section as a constant of variation (CV). If the condition of the carbon fiber tow was unstable, the deviation of the CV per section was large. In particular, the deviation of the CV per section was more than 0.15 when the arrangement of the fibers was changed, foreign substances were formed on the surface of the fibers, and damage occurred in the direction of the fiber width of more than 4 mm, so it was easy to evaluate the quality on CF tow.

“…One type of agricultural waste that has potential as a biocomposite reinforcement is areca husk fibers (AHFs) [6,7], which are quite abundant, have a low density, are renewable, can naturally decompose, and have good mechanical properties. Areca trees will bear fruit depending on the soil conditions, and the average areca tree in Indonesia after the age of 5-8 years produces fruits in the shape of a round egg with lengths between 3.5 and 7 cm.…”

In this study, alkali treatment was carried out on natural fibers to increase their mechanical strength, change the chemical composition, and clean the fibers of impurities. Areca husk fibers (AHFs) were soaked in an alkaline solution, and dried. Alkali-treated fibers were blended with preheated pine resin, and the tensile and impact strengths of the pine resin/AHFs biocomposites were evaluated. The fibers treatment, the tensile strength increased by about 11% and icreased by about 33% compared with untreated fiber biocomposites. Alkali treatment also increased The value of the Young's modulus of the fibers by about 9.2%. The impact strength of the pine resin increased by nearly 42% from the presence of 10% by weight AHFc content. For the pine resin/AHFs biocomposites, the impact strength increased 24% compared with untreated AHFs. The mercerization increased the adhesion of the fiber-matrix interface, enabling efficient transfer of tension from the matrix to the AHFs.By the SEM, increased adhesion bonding between the matrix and the fibers was also detected. This is significant, considering that tensile and impact strengths are some of the most important mechanical properties of a composite material thet are affeted by the bonding force between the matrix and the fibers.
