    On average, 7.8 white-tailed eagles (Haliaeetus albicilla) collide with wind turbines annually at the operating wind-power plant on the island of Smøla off the coast of central Norway. To better understand the impact of this wind-power plant on white-tailed eagles, we investigated how habitat utilization affected displacement effects. We collected data on habitat utilization in non-territorial subadult white-tailed eagles using global positioning system satellite telemetry (2004–2009). From these data, we estimated utilization distributions using the Brownian bridge movement model and analyzed them using Resource Utilization Functions. Home ranges were circa 10–30% smaller for subadults hatched on skerries and islets farther from the wind-power plant, and tended to be circa 40% larger during spring. Shallow sea, skerries, and islets were utilized extensively, as was marsh, heathland, and forest on the main island of Smøla. We noted lower selectivity for arable land and higher levels of differentiation in utilization among individuals for forest and islets. Females also had a nearly 4 times higher between-individual variation, which was likely due to longranging excursions. The within- and between-individual variation among seasons showed an annual pattern, with increasing between-individual variation toward summer. Displacement (indicated by an overall 40% proportional reduction in utilization) was more pronounced in the birds’ second and third calendar year compared with their first calendar year, and during autumn–winter. Reduced displacement during spring coincides with the white-tailed eagle pre-breeding period with increased flight activity. This may, in part, explain increased collision risk during spring. Possible displacement effects in white-tailed eagles may be avoided by siting wind-power plants farther inland or offshore, avoidance, collision risk, displacement, habitat use, habitat utilization, Haliaeetus albicilla, Norway,wind turbinesacceptedVersio

    A new road through northern Serengeti National Park is proposed to be built. The purpose of this study was to collect baseline data on soils along the route of the proposed road before its construction. The physicochemical properties were used to characterize the soil before the construction of the proposed road. Levels of soil macro-elements mainly potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na), and physicochemical properties: electrical conductivity (EC), pH, organic carbon (OC), soil organic matter (SOM), total nitrogen (TN), cation exchange capacity (CEC), phosphorus (P), aluminium (Al) were determined. Also, heavy metals: cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), nickel (Ni) and zinc (Zn) were analyzed. This study was done on the eastern (Ngorongoro District) and western (Serengeti District) segments of the proposed road. The ranges in average values obtained for the physicochemical parameters and metal concentrations in the soils were: 0.05–0.57 mS/m for EC, 6.5–7.9 for pH, 0.71–1.23% for OC, 0.30–0.74 g/kg for TN, 1.23–2.12% for SOM, 20.6–79.7 mg/kg for available P, 0.27–2.08 meq/100-g for available K, 9.89–30.3 meq/100-g for available Ca, 0.29–0.67 meq/100-g for available Mg, 0.06–1.35 meq/100-g for available Na, 11.04–33.12 meq/100-g for CEC, 46702.9–63963.3 mg/kg for Al, BDL for Cd, 24.70–101.55 mg/kg for Cr, 27.31–34.96 mg/kg for Cu, 32390.8–42439 mg/kg for Fe, 18.06–22.19 mg/kg for Pb, 957.1–1458.9 mg/kg for Mn, BDL for Hg, 20.24–32.52 mg/kg for Ni and 96.09–124.14 mg/kg for Zn. These observed levels indicate that the soils before road construction are unpolluted, moderately fertile and within the specifications of good agricultural soil. On the western segment of the proposed road, the soil will need application of fertilizers for better agricultural usage.

    Skripsi ini berjudul “Peranan Pelukis Ade Moelyana Dalam Mengembangkan Seni Lukis Pelepah Pisang di Cimahi Kajian Historis Tahun 1969-2010”. Permasalahan pokok yang dikaji dalam skripsi ini adalah bagaimana perkembangan seni lukis dari limbah pelepah pisang di Cimahi dari tahun 1969-2010 dan keterkaitannya dengan potensi ekonomi dari seni lukis pelepah pisang yang terabaikan. Metode yang digunakan adalah metode historis yang melalui empat tahap yaitu pengumpulan sumber lisan maupun sumber tertulis, kritik, interpretasi, dan historiografi. Untuk memperdalam analisis, penulis menggunakan pendekatan interdisipliner melalui kajian ilmu sosial dan ilmu ekonomi dengan memakai konsep-konsep seperti interaksi sosial, distribusi, ekonomi kreatif, kewirausahaan, dll. Teknik penelitian yang digunakan dalam penelitian ini adalah dengan menggunakan teknik wawancara. Hal ini dilakukan karena terbatasnya sumber tertulis yang mengkaji secara langsung mengenai permasalahan di atas. Berdasarkan hasil temuan di lapangan, seni lukis dari limbah pelepah pisang ini telah ada sejak tahun 1969. Seni lukis ini merupakan seni lukis yang unik karena menggunakan limbah dari pelepah pisang. Pada awal perkembangannya seni lukis ini tidak serta merta dapat diterima oleh masyarakat sekitar, dan barulah pada tahun 2002 seni lukis dari limbah pelepah pisang ini mengalami puncak perkembangan. Pasalnya seni lukis ini tidak hanya dipasarkan di Cimahi saja, melainkan sampai ke mancanegara. Seni lukis dari limbah pelepah pisang ini dapat dijadikan sebagai sektor ekonomi kreatif dan dapat dijadikan sebagai lahan lapangan pekerjaan. Banyak upaya yang dilakukan oleh pelukis untuk mengembangkan seni lukis dari limbah pelepah pisang, selain itu pula pemerintah turut serta dalam mengembangkan seni lukis pelepah pisang. Kata kunci : Seni Lukis Pelepah Pisang, Ekonomi Kreatif, Pemasaran This skripsi titled Ade Moelyama role in developing the art painting of wasted banana leaves in Cimahi of historical studies from 1969 to 2010. The main issue studied in this skripsi was “How Development Art Painting of Wasted Banana Leaves in Cimahi from 1969 to 2010 and linkages with economic potential of art painting of banana leaves neglected. The method used is the historical method through four phases of heuristics, criticism, interpretation and historiography. To deepen the analysis, the author use the approach interdisciplinary through the study of social and economic by using concepts such as social interaction, distribution, creative economy, entrepreneurship, and other. A research technique used in this research is to use interview techniques. This is done because of the limited resources that examines written directly on the above problems. Based on the research results, the art painting of wasted banana leaves has existed since 1969. This painting is a painting that is unique because it uses waste form banan leaves. In the early development of art is not necessarily acceptable to the local community, and then in 2002 the art painting of wasted banana leaves is experiencing the peak development. This is because not only do marketing painting around Cimahi but abroad as well. Painting of wasted banana stalks can be used as a creative economic sector and creates jobs. Lack of awareness of the various parties to make this painting became dormant. Many attempts were made by the painter to develop the art of waste banana leaves, in addition the goverment also participated in the development the art of painting banana leaves.
