Abstract

Tujuan penelitian untuk mengetahui unjuk kerja alat uji tarik komposit, bentuk benda uji yang akan diuji adalah komposit fragmentasi. Bahan yang digunakan sebagai bahan uji adalah komposit yang menggunakan matriks resin yukalac 157 dan sabut kelapa, sebelum membuat benda uji, metode perlakuan serat dengan asap cair terlebih dahulu dilakukan dalam 2 tahap (1) perendaman serat dengan asap cair dengan variasi 1, 2, dan 3 jam (2) kemudian serat dipanaskan dalam oven pada suhu 40 derajat selama 30 menit. Hasil penelitian menunjukkan bahwa pahat mampu menarik spesimen komposit fragmentasi telah mencapai 284 N, sedangkan perlakuan asap cair pada serat sabut kelapa berpengaruh terhadap peningkatan kekuatan komposit fragmentasi, kuat tarik maksimum terjadi pada serat perlakuan P2J sebesar 39,313 MPa. Dari hasil penelitian tersebut dapat direkomendasikan sebagai alat uji fragmentasi spesimen komposit.

Abstract

This study aims to identify the potential utilization of banana stem fiber (BSF) as a locally sourced composite material to support building infrastructure in North Maluku. The research focuses on analyzing the tensile and impact properties of the composite. An experimental method was used, incorporating different treatment durations for the fibers by immersing them in liquid smoke for 1, 2, and 3 hours. The treated fibers were then heated at 40°C for 30 minutes. The next step involved fabricating BSF-reinforced composite specimens by preparing the resin and fibers, with a fiber length of 10 mm and a composition of 30% BSF and 70% resin. Tensile and impact tests were conducted to evaluate the mechanical properties of the composites. The results showed that the tensile strength of the P3J composite increased to 88.351 MPa, representing a 3.79% improvement compared to the untreated composite (TP). Meanwhile, the impact strength showed the highest increase after 1 hour of immersion, reaching 10.911 KJ/m, which is 25.45% higher than TP. These findings indicate that liquid smoke treatment enhances the tensile and impact properties of the composite.

Abstract

The research aims to determine the effect of SSK treatment with liquid smoke on the morphology and acoustic properties of SSK reinforced composites. The research method is an experimental method with variations in fiber treatment by soaking in liquid smoke for 1, 2 and 3 hours. Next, after soaking the fiber, it is heated in an oven at 40ºC for 30 minutes, then the resulting fiber morphology is observed using a JEOL JCM 6000 SEM tool then SSK reinforced composites are made for acoustic testing, specimen making is done by preparing resin and long fibers. 1 cm fiber, 60% resin composition and 40% SBP, after drying a composite acoustic test specimen was made. The results show that SSK treatment with liquid smoke increases the fiber morphology to become rough and porous, so that the SSK reinforced composite has a sound absorption coefficient value for the SSK TP composite of 0.1175 db, while the SSK P1J, P2J, and P3J composites have a sound absorption coefficient value of 0.1304, 0.1199, and 0.1181 db. , this shows that the SSK P1J composite is better in sound absorption by 10.92% when compared with SSK TP, so it can be recommended as an environmentally friendly acoustic material.

Abstract

This article is a literature review of several studies oriented toward the treatment of natural fiber to improve the surface morphology and tensile strength of the fiber. The method used is to review several studies that describe the physical and mechanical properties of natural fiber with different treatments such as immersion of sago fiber in liquid smoke, coconut fiber in NaOH, palm fiber in seawater, and smoking of king pineapple fiber, and banana stem fiber with liquid smoke. The results of the review showed that the treatment was able to increase the tensile strength of sago fiber by 26.77%, coconut fiber by 81.25%, palm fiber by 67.40%, waru bark fiber by 59,97%, coconut fiber with limestone water 34,96 %, king pineapple fiber by 74.45%, and banana stem fiber by 43.78%. The effect of some of these treatments can also change the morphology of the fiber. So, it was concluded that treatment was needed to change the physical properties of the fiber in the form of morphology and mechanical properties in the form of better fiber tensile strength so that the fiber used as a composite reinforcement could improve the mechanical properties of the composite.
