Abstract

Fiberglass is the most common reinforcing fiber used in composites, with polymer matrices having high tensile strength and chemical resistance, including an excellent insulating property; however, they are non-degradable. Natural fiber reinforced polymer composites have advantageous properties such as lower density and price, when compared to synthetic composite products. In addition, hybrid composites may be obtained depending on various properties such as the fibers' length, structure, content and orientation, matrix bonding and arrangement. This study was carried out to determine the effect of adding Maleated Natural Rubber (MNR) from natural rubber as a coupling agent, in order to produce the highest tensile and flexural strength. The hand lay-up and vacuum bag methods with the Response Surface Method-Central Composite Design (RSM). -CCD) were used. The composite arrangement pattern was E-glass/OPEFB/E-glass, the volume fraction of OPEFB (oil palm empty fruit bunches):E-glass was 40:60, 50:50 and 60:40, the fraction volume of OPEFB + E-glass:matrix was 40:60, 50: 50, 60: 40 and the coupling agent were added by 9, 10 and 11% of the total epoxy resin used. Furthermore, the composite mold was made of glass with dimensions of 200mm x 50mm x 50mm. The results showed that the composite product obtained from both methods had a tensile strength value, which was influenced by the variable OPEFB fiber and epoxy resin. Meanwhile, the flexural strength was influenced by the OPEFB fiber and the quadratic factor of the epoxy-MNR resin.

Abstract

Catfish farming is a new livelihood being developed by the people of Lubuk Bendahara Timur village, Rokan Hulu district, Riau province. However, this effort faces challenges in terms of the use of expensive factory pellets, which account for about 60-70% of the total production cost. To overcome this problem, an alternative solution is proposed by producing fish pellets independently by utilizing palm oil waste in the village. Through this community service program, appropriate technology transfer was carried out for Lubuk Bendahara Timur villagers by empowering the local community in producing fish pellets independently. The implication of this program is the increased knowledge in optimizing the utilization of palm oil waste for fish pellet production, so as to reduce production costs, increase income, and manage waste effectively.

Abstract

Limbah biomassa dari industri kelapa sawit, seperti tandan kosong sawit (TKS) dan mesokarp, memiliki potensi besar untuk dimanfaatkan sebagai bahan baku dalam pembuatan biopelet, yang merupakan alternatif bahan bakar ramah lingkungan. Penelitian ini bertujuan untuk mengkaji pengaruh variasi komposisi antara TKS dan mesokarp terhadap kualitas biopelet yang dihasilkan, serta untuk memastikan bahwa produk biopelet memenuhi standar nasional Indonesia (SNI) 8675:2018. Penelitian ini juga mengeksplorasi variasi ukuran partikel 30 dan 60 mesh, serta penggunaan tepung tapioka sebagai perekat untuk meningkatkan kualitas biopelet. Empat perbandingan campuran bahan baku (b/b) diuji, yaitu 70% TKS:20% mesokarp, 50% TKS:40% mesokarp, 40% TKS:50% mesokarp, dan 30% TKS:60% mesokarp. Hasil penelitian menunjukkan bahwa biopelet terbaik diperoleh dari campuran TKS 40%, mesokarp 50%, dan tepung tapioka 10% dengan ukuran partikel 60 mesh. Biopelet tersebut memiliki kerapatan 0,89 g/cm³, kadar air 2,75%, kadar abu 13,07%, kadar karbon terikat 28,62%, dan nilai kalor 5239,43 kal/g, yang semuanya kecuali kadar abu, memenuhi kriteria yang ditetapkan dalam SNI 8675:2018. Penelitian ini memberikan kontribusi baru dalam optimasi pemanfaatan limbah kelapa sawit dengan menghasilkan biopelet berkualitas tinggi yang memenuhi standar nasional.
