Abstrak . Sifat fisis dan mekanis kayu kelapa dievaluasi pada tulisan ini. Tulisan ini bertujuan untuk menetukan karakteristik kayu kelapa dari beberapa lokasi di Sulawesi Utara (pada 4 daerah) dan Maluku Utara (pada 2 daerah). Penelitian dilaksanakan melalui uji laboratorium, dengan metode pengujian didasarkan pada ASTM (American Society for Testing and Materials). Hasil pengujian menunjukkan bahwa bagian batang kelapa bawah luar memberikan performa yang lebih baik (unggul) dibandingkan dengan bagian batang kelapa lainnya. Lebih lanjut, nilai dari hampir semua jenis pengujian, yang meliputi: berat jenis, kadar air, kuat tekan sejajar serat, kuat tekan tegak lurus serat, kekerasan, kuat geser sejajar serat, kuat tarik sejajar serat, penyusutan volumetris dan kuat lentur kayu kelapa, cenderung memberikan trend yang sama. Fenomena tersebut terlihat pada semua kayu kelapa dari berbagai daerah (lokasi pengambilan) yang diuji. Pada bagian akhir tulisan ini diberikan rekomendasi sehubung...

The increase in the export volume of coconut logs, which are materials that can efficiently substitute for conventional wood, demands that the quality of coconut wood classified quickly. However, due to the limitations of a grader as a human being, it is necessary to have assistance from machines or technology that can classify coconut wood quickly. Techniques that used for rapid classification can use computer visualization. Convolutional Neural Network (CNN) with the right architecture makes this method able to recognize and detect objects well, which influenced by computerized factors, large datasets, and techniques to train deeper networks. This study uses five types of CNN architecture, AlexNet, GoogLeNet, ResNet101, ResNet18, and ResNet50. The research results obtained for the classification of the quality of coconut wood using images show that the GoogLeNet architecture has the best classification performance among other architectures. GoogLeNet gets result with an average ac...

Coconut is a commodity that has an important role in the economy and culture. The various types of coconuts is significant capital in order to support coconut breeding program to obtain coconut varieties according to the needs of farmers and the market in general. North Maluku is one of the coconut center provinces in Indonesia. The research conducted from 2015 to 2017 in Bido Village, North Morotai District, Morotai Island Regency, North Maluku Province. The purpose of this study was to determine the origin of Bido coconut, as well as characterize and evaluate the morphological character, production, fruit components and fatty acid content and the potential development of Bido coconut. Bido coconut research method is done through direct observation. Data collected included the origin of varieties, morphological characters, production, fruit components and fatty acid content. The results showed that coconut Bido has copra yield potential about 4,36 tons/ha/year with main features in...

Kajian ini membahas leksikalisasi bagian-bagian pohon kelapa dan fungsinya dalam kehidupan masyarakat Jawa di DIY, khususnya wilayah Kota Yogyakarta dan Kabupaten Bantul. Kajian berkenaan dengan upaya inventarisasi dan pendeskripsian atas fungsi dari leksikalisasi. Kajian ini memanfaatkan pendekatan etnolinguistik. Dengan demikian, leksikalisasi dipahami sebagai cermin cara penutur memaknai fungsi sebuah realita bagi kehidupan mereka. Data kajian ini berupa kata (leksem) yang menunjuk bagian tertentu pohon kelapa. Data diperoleh dengan metode simak yang dilengkapi dengan metode cakap. Pembahasan pada kajian ini bersifat deskriptif kualitatif. Analisis memanfaatkan analisis semiotik. Pada tahap awal, analisis menerapkan metode analisis komponen. Berdasarkan analisis, ditemukan 26 leksikalisasi bagian pohon kelapa dan sekitar 30 leksem nama produk terkait pemanfaatan bagian pohon kelapa. Berdasarkan klasifikasi, fungsi pemanfaatan bagian pohon kelapa itu dapat dipilah dalam 6 ranah, y...
Karakter Morfologis dan Hubungan Kekerabatan Beberapa Genotipe Kelapa (Cocos nucifera L.) di Kecamatan Silau Laut Kabupaten Asahan : Morphological Characteristics and Phylogenetic Relationship of Several Genotypes of Coconut (Cocos nucifera L.) in Silau Laut District Asahan Regency

This research aimed to identify the morphological characteristics and phylogenetic relationship of several genotypes of coconut in Silau Laut district Asahan regency Sumatera Utara. The research was conducted from April to Mei 2017 by survey method based on coconut descriptor of International Plant Genetic Resources Institute (IPGRI) with sampling technique using accidental sampling. This result of research showed that in Silau Laut district there were 27 genotypes of coconut been identified. The result of morphologycal characteristics for crown shape (spherical, hemispherical, X-shaped ‘silhouette’), flower shape (normal and additional spathes or bracts), fruit shape (oblong, ovoid, angled, round), nut shape (pointed, ovoid, almost round, oblate). The closest phylogenetic relationship is G41 and G42 with coefficient dissimilarity 3,00 and farthest phylogenetic relationship is G40 and G45 with coefficient dissimilarity 12,53. The result of dendogam showed at scale 18 was formed 5 go...

Fish catch handling highly influential by the quality of fish that must kept to be fresh. Maintaining the quality of the catch is done with good handling and correctly, especially the storage of fish is highly influenced by the quality of insulation (Insulator). Polyurethane is a solid plastic foam mixture by polyol and Isocynate commonly used as a thermal insulation material on fish hold. Coco fiber derived from coconut fruit seeds contain about 30% of the seed oil. Part of the cross section in the unit cell has a central hollow fibers that serves as an acoustic and thermal insulator so as to decrease the bulk density of the fiber is very well used as an insulator because it has a low thermal conductivity. The addition of coconut fiber as a biodegradable that has a physical properties as a heat insulator aims to minimize use of polyurethane as insulation, addition of Coco fibre can be done until 70%, and the addition of 95.5% density and water absorption reached 26.8%. Ability to a...

This research used coconut fiber for composite material because the potential for its utilization was very large and not yet been optimally done in Indonesia. This study aimed to determine the effect of variations in fiber composition towards sound attenuation and porosity. Composite was made 3 variations of coconut fiber composition, namely 40%, 50%, and 60%. The results of the sound attenuation test, composite that has the greatest attenuation power was composite with variation in coconut fiber composition of 60% with an average NAC value of 0.1446. While the highest porosity value was also obtained from composite with variation in coconut fiber composition of 60% with an average porosity value of 28.0663%.
