Abstract

Fiberboard uses a lot of agro-industry waste materials combined with synthetic adhesives containing formaldehyde. The weakness of this adhesive is that it can cause health problems such as cancer and eye irritation. Lignin has properties and content similar to formaldehyde. Nipah has lignin and cellulose content that can be developed into binderless fiberboard. The purpose of this study was to analyze the potential of Nipah frond fiber to make a binderless fiberboard. The characteristics of fiberboard that will be explored include density and water content. Nipah frond binderless fiberboard is made using a press machine with a pressure of 50 bar, and a temperature of 100oC for 20 minutes. The density between 0.46-0.52 which is by the requirements of SNI 03-2105-2006 and the water content of 5.98% - 7.70% is also by the requirements of JIS 5908: 2003 and SNI 03-2105-2006. Based on these results, it can be concluded that Nipah fronds can be used as raw material for binderless fiberboard.

Abstract

Nypa palm (Nypa fruticans) possesses various potential uses, one of which is as a source of cellulose. Cellulose can be a raw material in industries such as paper production, pharmaceuticals, and biomaterials. However, the fiber of the nipa palm frond tends to be brittle and fragile. Reducing the particle size of the fiber can enhance its mechanical strength, which can be achieved through acid hydrolysis using a 10% strong acid solution. This study aims to characterize the cellulose extracted from nipa palm fronds after acid hydrolysis. The alpha-cellulose content obtained was 39.626%, with a lignin content of 18.633%. Morphological characterization revealed that the cellulose particles ranged from 615.814 μm to 840.719 μm in size. Scanning Electron Microscope–Energy Dispersive X-ray (SEM-EDX) analysis showed that the fibers were elongated with irregular lengths and were composed primarily of carbon and oxygen elements. Fourier Transform Infrared (FTIR) spectroscopy identified the presence of O–H, C–H, and C–O functional groups as the main components of cellulose, along with C=O groups associated with lignin. These findings indicate that acid hydrolysis effectively reduces the particle size of nipa palm frond fibers and enhances their physical characteristics, making them more suitable for advanced material applications.

Abstract

Desa Widarapayung Wetan mempunyai potensi yang khas yaitu yutuk atau undur – undur laut. Pengolahan yutuk saat ini masih terbatas hanya dijadikan keripik ataupun hanya digoreng yang dijual seharga Rp 2.500 per bungkus. Harga jual yutuk yang relatif rendah dan proses pengolahan yang masih terbatas menjadi salah satu penyebab produk olahan yutuk sulit bersaing. Diversifikasi dan pengolahan yutuk menjadi produk yang bernilai tambah perlu dilakukan untuk meningkatkan nilai jual dari yutuk. Yutuk dapat diolah menjadi tepung yutuk. Tepung yutuk kemudian dapat dimanfaatkan menjadi produk olahan lainnya sesuai dengan keinginan.Tepung yutuk diharapkan dapat meningkatkan nilai jual yutuk. Kelompok Nelayan Yutuk Desa Widarapayung Wetan dibekali ilmu dan wawasan untuk mengolah yutuk melalui kegiatan pelatihan pembuatan tepung. Kegiatan terbagi menjadi dua sesi, sesi pertama diawali dengan cara untuk melakukan pengeringan dan penepungan yutuk kemudian dilanjutkan dengan sesi kedua yaitu mengolah yutuk menjadi stik yutuk. Peserta kegiatan mengikuti rangkaian kegiatan dengan antusias. Diharapkan melalui kegiatan ini masyarakat desa Widarapayung Wetan khususnya kelompok nelayan Yutuk dapat meningkatkan nilai jual yutuk dengan menjual variasi olahan yutuk yang berasal dari tepung yutuk
