Abstract

High demands for trees as the raw material of paper can disrupt the stability of the environment. It is necessary to find alternatives from other materials which are more environmentally friendly. This study aims to determine the quality of paper made from combining sugarcane bagasse with cassava peels or with corn husks using PVAc or tapioca starch adhesives. A completely randomized 2 x 2 factorial design with five times replication was used. The parameters tested were the tensile and tear resistance of the paper using a micrometer and a universal testing machine. A sensory analysis from panelists was also conducted. The combination of J1P1 produced a paper with the highest tensile strength (11.30 MPa) and the highest tear strength (1.82 MPa). The combination of J2P2 produced a paper with the lowest tensile strength (10.35 MPa) and the lowest tear strength (1.62 MPa). Variance analysis showed that the type of adhesive used showed a significant result on both tensile and tear resistance but material choices and interaction between materials and adhesive choices was not significantly different from the result on both tensile and tear resistance. Sensory testing shows that the combination of J1P1 was preferred the most. It can be concluded that the combination of J1P1 appeared to be the best combination.Keywords: Handmade paper, sugarcane bagasse, cassava peels, corn husk, PVAc tapioca starch, adhesive

Abstract

The pole is needed to increase ecological stability. This research analyzes the composition and structure of the pole community in the Girimanik Natural Forest Area, Setren Village, Slogohimo District, Wonogiri. The objective is to acquire a representative depiction of the pole community's structure and composition in this area. The research employed 25 plots, each measuring 10x10 m, covering a total area of 0.25 ha, strategically established in the region of the Girimanik Natural Forest Area. Data collection utilized the quadrat method. The findings revealed 41 species across 23 families, with a total basal area of 5.06 m². The species Schima walichii (DC.) Korth. and Quercus sundaica Rehder are the two most dominant species, exhibiting Important Value Indices of 40.41% and 37.33%, respectively. The Moraceae family encompasses the highest number of species, totaling five. The Diversity Index (H’) for pole species in the Girimanik Natural Forest Area is categorized as moderate, with an H’ value of 1. Conversely, the Dominance Index (C) is classified as high, with a value of 1.15. This study can be concluded that further research is needed to examine or find rare species of poles, so that more comprehensive conservation follow-up is needed for these rare species.
