Penggolongan 23 Jenis Rotan Indonesia Berdasarkan Kerapatan Dan Kuat Tarik Sejajar Serat

Abstract

Rattan utilization is mainly determined by its physical and mechanical characteristics of density and tensile strength, where the higher the physical and mechanical properties, the better quality of the cane. In South East Asia region including Indonesia, two of eight genera, Calamus and Daemonorops are classified into high economic value, however the physical and mechanical characteristic of lesser known rattan species has not been studied intensively. This paper classifies 23 of lesser known rattan species into four classes based on its density and tensile strength parallel to grain. Density was measured based on gravimetric method and tensile strength parallel to grain was tested using Universal Testing Machine (UTM). Results show that in term of physical and mechanical properties, one species belongs to class I (very good), twelve species are classified into class II(good) and III (moderate). Ten rattan species are grouped into class IV (poor). Among 23 rattan species, highly recommended commercial rattan species are Calamus holttumii Furt., Calamus nematospadix Becc., and Korthalsia celebica Becc. While, Calamus sp., Korthalsia rostrata Blume and Daemonorops sabut Becc are less recommended.

Modelling the habitat suitability of rattan (Calamus zollingeri) in Lore Lindu National Park, Central Sulawesi

“…In Central Sulawesi, C. zollingeri is known by the local name rattan batang (Rustiami, 2011). C. zollingeri is one of the large-diameter rattan species that has a long-lasting carrying capacity for furniture frames (Abdurachman et al, 2017). C. zollingeri is used by the community as food, medicine, and crafts, such as chairs, tables, baskets, and other household tools (Maarif et al, 2021).…”

Diversity of Rattan Species in Production Forest in Central Sulawesi, Indonesia

“…Based on the development of the global demand for highquality rattan types, the business of logging rattan species has increased as well [11,12]. The need for world rattan from Indonesia reaches 190,000-220,000 tons per year [5,13]. The consequence is a decreasing population size of rattan types because rattan harvesting is not balanced with cultivation efforts.…”

Klasifikasi Mutu 11 Jenis Rotan Indonesia Berdasarkan Kerapatan Dan Keteguhan Lentur

“…memiliki karakteristik sedang (kelas mutu III). Selain itu, empat jenis rotan asal Sulawesi dari hasil penelitian 23 jenis rotan Indonesia yang diteliti oleh Abdurachman et al (2017) yaitu C. boniensis Becc. ex Heyne dan K. celebica Becc.…”

“…Dua jenis rotan asal Sumatera dalam Abdurachman dan Jasni (2015) memiliki karakteristik baik (kelas mutu II) untuk C. manan Miquel dan karakteristik buruk (kelas mutu IV) untuk Plectocomiopsis geminiflora (Griff) Becc. Hasil penelitian 23 jenis rotan Indonesia yang diteliti oleh Abdurachman et al (2017) menyatakan bahwa sepuluh jenis rotan asal Sumatera antara lain C. holttumii Furt. memiliki karakteristik sangat baik sampai baik (kelas mutu I -II), C. oxleyanus Teijsm.…”

“…Hasil analisis korelasi menunjukkan bahwa terdapat hubungan linear positif yang nyata baik modulus elastisitas terhadap kerapatan (r = +0,477; P<0,01; Gambar 2a), modulus patah terhadap kerapatan (r= +0,593; P<0,01; Gambar 2b), maupun modulus elastisitas terhadap modulus patah (r = +0,647; P<0,01; Gambar 2c). Ketiga korelasi tersebut memiliki nilai koefisien korelasi yang lebih besar dari hasil penelitian Abdurachman dan Jasni (2015) dengan koefisien korelasi sebesar +0,313 dan Abdurachman et al (2017) dengan koefisien korelasi sebesar +0,419.…”
