“…Identifying the transition from juvenile to mature wood is a first step to elucidate the quality of wood and to improve its utilization. Previous study identified that 30.4-38.9% of Samama wood (Anthocephalus macrophyllus), which is endemic in eastern Indonesia (Celebes and Moluccas islands), showed maturity features at 8 years old (Cahyono et al, 2015). The wood is classified into strength class of III and IV (Cahyono et al, 2012).…”

Relatively little information is available regarding the correlation between wood and veneer quality, especially for Samama wood, an endemic wood species in eastern Indonesia. This study addresses the quality of 8 years old Samama wood and its effect on the veneer quality. Samama wood quality was determined by evaluating its specific gravity, moisture content, fiber dimensions, and microfibril angle from pith toward bark. Meanwhile, veneer quality was assessed by examining veneer thickness and lathe check characteristics. Geometry factor model was constructed to elaborate the quantities of lathe check from pith toward bark. Results show that fair variations of veneer thickness, ranging from 1.5 mm to 3.0 mm, could be obtained from Samama wood. The quantity, depth, and length of lathe check were noticeably decreasing toward bark. Further, in the same manufacturing process, geometry factor was determined as the dominant factor over other wood properties in affecting the frequency of lathe checks from pith towards bark. These facts should be put into consideration in producing veneer from Samama wood. Moreover, these results enlighten the potential of Samama wood as plywood and other excellent veneer-based products.

“…Kayu juvenil masih mengalami perubahan sifat pada dimensi serat, kerapatan, dan sifat lainnya. Beberapa penelitian mengenai kayu juvenil di Indonesia diantaranya pada kayu mangium (Lukmandaru, 2012;Rulliaty, 2008), sengon dan jabon (Darmawan, Nandika, Rahayu, & Fournier, 2013), serta samama (Cahyono et al, 2015). Semua penelitian tersebut menyatakan bahwa sampai umur 6 tahun, pada pohon yang diteliti masih terdiri dari kayu juvenil.…”

Krasikarpa wood (Acacia crassicarpa A. Cunn.) is one of the fast growing peatland species for pulp and paper production. Pulp and chemical properties of krasikarpa wood under 4 years old have not been studied intensively. This paper examines pulp and chemical properties of krasikarpa wood during 1-4 years growth. Wood samples were taken from peatland area of Industrial Plantation Forest, PT. Arara Abadi, Riau. Chemical content examined includes extractives content in the solubility of ethanol benzene, lignin, and cellulose contents, while pulp properties studied were basic density, pulp productivity, and wood consumption. Wood samples were cooked using kraft pulping method with 18% alkali active, 25% sulfidity, wood to liquor ratio of 1:4, and temperature of cooking at 165°C for 3 hours. Experiment was designed based on Completely Randomized Design. Results showed that the age factor had a significant effect on all aspects studied. Based on further testing of LSD (Least Significant Differences

“…Kayu sebagai bahan yang biodegradable memiliki kelebihan sekaligus kekurangan, yaitu 1) Kayu dapat mengalami kerusakan akibat agen perusak hayati maupun non hayati (Priadi 2011;Bahtiar & Arinana 2012) dan 2) Kayu sebagai bahan konstruksi tersedia dalam waktu yang cukup singkat dibandingkan dengan baja atau beton yang non renewable. Sebagai contoh, kayu memiliki kualitas yang sama baik setelah melewati umur 5 tahun (Cahyono et al 2015). Kayu jati unggul jika ditebang kurang dari 5 tahun terbukti memiliki sifat kayu yang inferior dan diperlukan peningkatan kualitas (Wahyudi et al 2014).…”

ABSTRAK Wisata sejarah merupakan salah satu aspek pendukung industri wisata, baik lokal maupun nasional. Salah satu destinasi wisata di Maluku yang menyajikan keindahan arsitektur dan strukur kayu adalah masjid tua Wapauwe. Walaupun bangunan utama masjid hanya berukuran 10 x 10 m, masjid ini merupakan salah satu kekayaan budaya Islam di Maluku yang tetap berdiri kokoh dan terawat sejak dibangun pada tahun 1414 M. Selama masa penggunaan, tentunya bangunan akan mengalami deteriorasi. Oleh karena itu, dilakukan penelitian untuk melihat keandalan bangunan masjid tua Wapauwe yang terletak di Desa Kaitetu, Kabupaten Maluku Tengah, Provinsi Maluku. Metode forensik dilakukan pada semua komponen bangunan dan kemudian disesuaikan dengan standar kelayakan bangunan. Hasil penelitian menunjukkan bahwa bangunan masjid masuk ke dalam kategori masih baik dan layak digunakan. Struktur kayu soko guru (tiang), dinding, dan kuda-kuda masih terlihat kokoh dan terawat, namun terdapat gejala kapilaritas air pada beberapa bagian dinding dan fondasi bangunan. Kayu yang digunakan adalah jenis kayu nani (Xanthostemon verus), linggua (Pterocarpus indicus), meranti merah (Shorea pinanga), dan bintanggur (Calophyllum inophyllum). Sebagai rekomendasi diperlukan perawatan ringan pada atap yang sedikit mengalami kerusakan dan metode khusus menghindari kelembapan pada dinding dan fondasi. Selanjutnya, perlu dilakukan penelitian lanjutan pada struktur anatomi kayu, pengujian rangkak (creep), dan umur kayu untuk memastikan umur dan kekuatan kayu dalam jangka panjang. Kata kunci: forensik, keandalan bangunan, konstruksi kayu, masjid
