"The main effect of logging is to create an artificial disturbance regime resulting in canopy gaps and disturbance to soil, seedlings and the forest understory. The effects of logging on the physical environment of a lowland dipterocarp forest in Central Kalimantan are being investigated. A range of approaches are being applied to characterize these impacts. The effect of logging on cnopy cover, seedling density and soil disturbance are recorded to produce low resolution maps of the plots before and after logging. More detailed information about changes in canopy structure is determined using image analysis of hemispherical canopy photographs. "

"Nanostructured zinc oxide (ZnO) was synthesized via a sonochemical method. The effect of the duration of ultrasonic irradiation in a continuous mode on the generated particles was investigated. Additionally, the effect of flowing either air or nitrogen during the sonication process was investigated. Zinc nitrate and ammonia water-based solutions were selected as chemicals without the addition of other surfactants. The generated particles indicated that a wurtzite structure of ZnO in a hexagonal phase was formed with a crystalline size that increased as the ultrasound irradiation time increased. The morphology of the generated ZnO particles could be changed from flowerlike to needlelike structures via continuous ultrasound irradiation over one to two hours, resulting in increases in the particle lengths and decreases in the particle diameters from 200 to 80 nm. Photoluminescence intensity was also increased with increases in the ultrasonic irradiation times. Photoluminescence spectra were also influenced by the atmospheric environment. Two bands centered at 390 and 500 nm were generated under a nitrogen environment. On the other hand, a single wide band with a peak at around 430 nm was found for particles generated under an air environment. It can be applied for light emitting diodes (LED) or laser fabrication with a controlled emitting band."

"ABSTRAKPerkembangan fisik lingkungan pesisir di Kabupaten Manokwari tidak terlepas dari lajunya pertumbuhan jumlah penduduk. Seiring dengan lajunya pertumbuhan Jumlah penduduk didaerah perkotaan Manokwari, menyebabkan tingginya permintaan lahan permukiman. Analisis data kependudukan menyajikan dinamika pertumbuhan jumlah penduduk massif di Kecamatan Manokwari Barat dan sekaligus kecamatan ini menjadi kecamatan yang padat sejak tahun 2000.Peningkatan jumlah penduduk di kecamatan ini selaras dengan pola pengunaan tanah permukiman tanpa di dukung dengan penyediaan sarana dan prasarana sehingga menimbulkan kerusakan dan pencemaran lingkungan pesisir. Upaya Pemerintah Kabupaten melaksanakan program pengembangan wilayah ternyata belum berkesesuaian dengan kebutuhan penduduk Kecamatan Manokwari Barat di bidang sarana-prasarana tersebut.Temuan-temuan yang di peroleh melalui rangkaian analisis Super Imposed peta-peta tematik, Conten Analisis dokumendokumen perencanaan Kabupaten Manokwari, dan Gap Analisis dalam mengukur kesenjangan pada program pemerintah dengan kondisi ruang terbangun pada wilayah studi. Diharapkan penelitian ini dapat bermanfaat dalam memberikan kajian tetang tori kesesuaian pembangunan, dalam konsep Kota Berkelanjutan.

ABSTRACT

Physical development of the coastal environment in Manokwari not independent of the speed of growth of the population. Along with the growth speed Manokwari total population of urban areas, resulting in high demand for residential land. Analysis of demographic data presents the dynamics of population growth in the district of Manokwari West massif and at the same time these districts into subdistricts solid since 2000.

The increase of population in the district is consistent with the pattern of use of the land settlement without the support with the provision of facilities and infrastructure, causing damage and pollution coastal environment. District Government efforts to implement the program of regional development is not yet in conformity with the needs of the population in the District of Manokwari West the field of infrastructure.

The findings were obtained through analysis of super imposed a series of thematic maps, Conten Analysis of planning documents Manokwari District, and Gap Analysis to measure the gap in government programs with the condition of the room woke up in the study area. This study is expected to be useful in providing conformity assessment tori neighbor of development, the concept of Sustainable Cities."
