Abstract

Noken ialah tas tradisional dari anyaman atau rajutan serat tumbuhan, diakui sebagai warisan budaya asli dari tanah Papua. Serat alami noken bervariasi tergantung kondisi habitat dan kearifan lokal, sehingga noken dari dataran tinggi berbeda bahan, teknik dan motif dengan dari dataran rendah atau pesisir. Penelitian ini bertujuan mendiskripsikan praktek tradisional pembuatan noken dari serat daun Nanas (Ananas sp.) oleh masyarakat suku Mee di kampung Kaliharapan Nabire. Penelitian ini dirancang dengan metode deskriptif dengan teknik wawancara dan observasi lapang. Variabel penelitian meliputi seleksi dan pengambilan daun nanas, jenis nanas, pemisahan serat daun, pengeringan, pewarnaan, dan penganyaman serat nanas menjadi rajutan noken, serta ukuran dan harga noken. Hasil penelitian menunjukkan bahwa serat noken suku Mee berasal dari dua jenis nanas, yaitu Abicaxi dan Red Spanish. Daun nanas tua dipetik dengan intensitas tidak lebih dari 25% dan 35 % per tanaman setelah buahnya dipanen, dikumpulkan, diikat dan diangkut kerumah, diseleksi dan dihilangkan durinya dengan pisau. Daun segar, digaruk-garuk dari pangkal ke ujung satu arah menggunakan alat sederhana, pengaris besi yang dibengkokkan menyerupai garpu tala, guna menghancurkan kutikula daun. Serat disatukan dan ditarik dengan tangan, kemudian serat di jemur (digantung) dibawah sinar matahari, selama 12 jam, sampai kering (berwarna terang). Serat dipilin manual diatas paha dengan tangan sampai menjadi serat benang nanas, kemudian dirajut menggunakan jarum payung menjadi noken.  Kunyit untuk warna kuning, daun bayam untuk hijau dan biji binahong untuk merah adalah pewarna alami dan kusumba untuk pewarna sintetis. Ukuran noken dikelompokkan menjadi tiga, besar, sedang dan kecil, dengan harga dari Rp 50.000 – 200.000, tergantung ukuran dan motif, polos dan bermotif. Noken memberikan pekerjaan informal dan penghasilan tambahan bagi perempuan masyarakat suku Mee.

Abstract

Flood is number one Indonesian natural disaster in the last 10 years and its occurrence at Manokwari is frequently reported. Biophysical condition is playing a key role in carrying capacity of this catchment area.This study is to determine biophysical characteristics of Wosi Watershed to manage and mitigate flooding in Manokwari. Spatial analysis and field observation methods were used to collect the data. Biophysical variables are rainfall, watershed morphometric, slope, and land used. Carrying capacity is measured using flow regime coefficient and annual flow coefficient. The results showed that the heavy rainfall (> 100 mm) throughout the ten years with 10.5 wet months at average resulting very wet tropical climate. This watershed has an area of 2,346.32 ha, its circumference of 29.95 km2 with river length of 8.38 km resulting 0.33 (triangle) and 1.027 (triangle) for Rc and Re, respectively. This morphometry is rectangular and slightly oval(triangular) formed of four rivers with drainage pattern of dendritic, which resembles the shape of a tree branch/twig. Steep slopes are dominant (58.5%), with non-forest area (62%) of the flat and steep slope for settlement (698 ha), and flat slope for mixed dry farming (707 ha). From 2016-2020, river water flow changes rapidly from low to very high to generate flooding, but the carrying capacity is sometime changeable from good to bad. Water drainage, retaining walls, replantation, early warning system, and flooding leaflets mitigation campaign, are structural and non-structural mitigation could be parallelly conducted to manage and mitigate the flooding risks in future.

Abstract

Wood is very susceptible material from termite attacks. A simple, cheapest method to prevent this attack is coating treatment. On this work, three inferior wood species collected from Manokwari – Papua Barat, namely Pulai (Alstonia scholaris), Binuang (Octomeles sumatrana), and Jambu (Syzygium sp.) were coated with two coating systems of oiled and water- based coatings. Coating was applied using paint brush on wood samples with dimensions, 50 cm long x 5 cm wide x 2.5 cm thick. Durability was conducting with grave yard test, where half-length of wood samples, coated and uncoated samples, were buried on the yard for the three consecutive months. Wood durability was evaluated using two variables, wood weight loss, and wood damage, respectively, and analyses into other variables likes wood resistance class, level of resistance, degree of damage, and natural durability classes. The results indicated that both coated systems, oiled and water based, had an average of spreading rates from 0.005-0.015 g/cm2. Weight loss of three inferior species of wood recorded from the control samples are 38.65%, 12.12%, and 6.14% for Pulai, Binuang and Jambu. Treatment with coating systems, weight loss could be prevented into 95.1%, 58.2% and 56.0% to control for Pulai, Binuang and Jambu, respectively.  Wood resistance class of Pulai is IV. Binuang and jambu species initially is Moderate Resistant (III) and improve into Resistant (II). It is summarized that coating systems available in the local market could protect wood from subterranean termites.
