Sawdust and sago pulp residue were homogenized with a hammermill to obtain 60 mesh powder sizes. Concentrations of binding agents ranging from 30 - 70% based on volume/weight were employed. Hot clean water was used for mixing wood powder and the binding agents by hands. Variables of wood pellets examined are diameter and length (cm), moisture content (%), density (g/cm3), ash and volatile content (%), fixed carbon (%), and caloric value (cal./g) according to SNI 8021: 2014. The results indicate that the wood dimension for a diameter of 0.45 cm and a length of 3.78 cm on average are matched the standard. Wood pellets have an average of moisture content 16.87%, higher than the standard of 12%. Means for density and ash content are 0.8 g/cm3 and...

Thirty-one species of air-dried timber with sample size of 13 cm × 6 cm × 4 cm gathered across Papua were used for density measurement and macro-features observation, cover of colors, grain orientation, and wood texture. The results showed that whitish and straw to yellow brown are dominant color of timber mostly harvested from Papua tropical forest. Their grain orientations are mostly straight, while their textures are medium. With regard to their density, Xantostemum spp is the heaviest timber having density of 1,25 g/cm3 while Alstonia scholaris is the lightest species of timber with density of 0.29 g/cm3. Therefore, majority Papua`s timber species studied are classified into light class species or low density timbers. Pulp and paper, veneer, plywood, flooring, meubels, indoor urnitures and handles or woody utensils are the potential uses of these timber species.

Firstly, the conventional approach using column chromatography (CC), and preparative thin layer chromatography (PLC) eluted with benzene:ethyl acetate: formic acid (5:4:1, and 5:4:2, respectively), followed by CC eluted with benzene:methanol (3:2) were used to separate and isolate berberine from the chloroform fraction of Tali kuning. Structural elucidations of the isolated compounds were conducted using nuclear magnetic resonance (NMR) and mass spectrometry (MS). Secondly, a rapid and simple approach use the integrated intensities of proton signals for H-13 and H-8 of berberine on 1 H-NMR spectra, then the qualitative and quantitative determination of berberine in Tali kuning can be achieved directly from the crude extracts using 1 H-NMR. The proton signals for H-13 and H-8 of berberine on 1 H-NMR spectra, which appeared at empty region...

The chemical compounds of essential oils in this study were analyzed by gas chromatography-mass spectrometry (GC-MS) and the physiological effects of essential oils on human were analyzed via the sense of smell olfactory system. Physiological parameters of systolic blood pressure, diastolic blood pressure, pulse rate, stress index, and brain wave were recorded before and after sniffing essential oils. The result shows that the main compound of M. leucadendron, C. odorata, and P. cablin is 1,8-cineole, Caryophyllene and Patchouli Alcohol, respectively. Our results demonstrated that M. leucadendron and C. odorata oil odors possessed sedative effect and P. cablin oil odor had tendency to contain stimulating effect on human physiologies.

In total 51 glulam, 17-combined layers with three replications, were tested for flexural strength, density, and delamination. The results show that laminating increased the density compared to that of the original material. Plain sago bark has higher MOR and MOE than when it is combined with the two other species into glulam, with reductions of 8.2 and 43.9%, respectively. Delamination mostly occurred following 24 h of water immersion for the glulam of sago bark and its combinations, but it was absent in glulam without sago bark.

Mangrove provides food, material construction, firewood, medicine, shelter and others. This research is designed to determine the traditional practices of utilizing mangrove vegetation used for medicinal material remedieson for five ethnicgroups in Papua. Field observation, and intensive literature reviews were used to collect the data and information required. The results showed that seven spesies of mangrove belonging to five families were used for medicinal puposes by five ethnic groups in Papua. Utilizations of mangrove as traditional medicines could be used for treatments for twelve diseases or health syndromes, ranging from mosquito repellency, scabies medicine, cleanse for pregnancey, children’s speaking ability, insecticides, malaria medicine, tooth medicine, diarrhoea, energy booster and stimulant for birth delivery.

Research-based on techniques for observation, interviews, and case studies. Measurement of respondents' perceptions and attitudes is carried out using instruments in the form of questionnaires that refer to the Likert scale. Data analysis was performed descriptively to describe the level of perception, attitude with simple non-parametric linear regression. Maruni protected forest has the potential of limestone with 11 mineral elements, 5 of which are the largest Ca (93.62%), Si (2.45%), Mg (1.58%), Al (0.97%)), and K (0.47%). This forest allows conversion area, from an area of 969.84 ha with limestone potential of only 250 ha (25.78%), another 719.84 ha (74.22%) can still be designated as a protected forest. The public perception of conversion to cement mining was 59.03% negative, 14.83% neutral, and 26.12% positive. While the attitudes of the community 43.1% accept, 38.94% neutral and 47.92% reject the conversion to become cement mining. The community hopes that there will be economic improvement, community empowerment, and employment, especially in affected communities.

Namun seberapa luas daerah yang rentan terhadap kondisi ini, belum ada data mengenai hal tersebut. Untuk itu perlu dilakukan penelitian untuk mengetahui sebaran tingkat kerentanan bencana banjir di kota Sorong. Penelitian ini merupakan penelitian deskriptif menggunakan analisis dan sebaran pola tingkat kerentanan banjir dengan teknik analisa data menggunakan overlay, scoring, dan layout berdasarkan software Arc View 10.5. Hasil penelitian menunjukkan bahwa tingkat kerentanan banjir di Kota Sorong diklasifikasikan dalam 4 tingkat kerentanan banjir yang meliputi sangat rentan, rentan, kurang rentan, dan tidak rentan. Seluas 4, 53 % wilayah kota Sorong tergolong sangat rentan terhadap banjir, rentan banjir seluas 33,65 % yang kurang rentan sebasar 42.11 % dan daerah tidak rentan sebesar 19,71 %. Wilayah yang harus diwaspadai karena rentan dan sangat rentan banjir adalah seluas 38,18 % meliputi Distrik Sorong Timur, Manoy, Sorong, Sorong Kota dan Sorong Barat. Daerah tersebut adalah pusat pemerintahan dan termasuk daerah padat pemukiman penduduk.

Pada bagian awal buku, dikenalkan secara singkat pengertian dari mangrove, sumberdaya mangrove, distribusi sumberdaya mangrove di dunia, penyebarannya di Indonesia, Provinsi Papua dan Papua Barat, bahkan pada masing-masing kabupaten/kot. Aspek-aspek pemanfaatan & pengelolaan sumberdaya mangrove, mulai perencanaan, survei lapangan, penebangan, penyaradan, pengangkutan kayu log mangrove ke industri dibahas dalam buku ini. Praktek atau sistim silvikultur yang digunakan juga diterangkan dalam bukuk ini. Bentuk bentuk kelola perusahaan, dan partisipasi masyarakat lokal dalam kegiatan pemanfaatan sumberdaya dimuat pada bagian akhir. Beberapa potensi hasil hutan bukan kayu dari mangrove, juga disertakan dalam pembahasan buku ini, termasuk bentuk bentuk pemanfaatan limbah-limbah dari pemanfaatan kayu mangrove untuk produk kerajinan atau industri kreatif bagi masyarakat sekitarnya.
