    Kepulauan Anambas yang terletak pada Provinsi Kepulauan Riau memiliki potensi dan daya tarik pariwisata tropis yang indah dengan kepulauan eksotisnya. Kepulauan Anambas dinobatkan sebagai pulau tropis terbaik di Asia pada tahun 2012 oleh CNN Internasional. Pembangunan eco floating resort sebagai sarana penunjang pariwisata pada Kepulauan Anambas diharapkan dapat meningkatkan wisatawan domestik dan mancanegara di Kepulauan Anambas. Eco floating resort mengambil konsep ramah lingkungan dengan pemasok listrik utama menggunakan panel surya. Payload luasan adalah 1.723,28 m2 untuk 48 orang pengunjung dengan 16 orang crew . Setelah dilakukan analisis teknis diperoleh ukuran utama LoA: 48 m; B: 18 m; D: 4 m; dan T: 1.8 m. Kondisi geografis lokasi Eco floating structure dengan tinggi gelombang 0 – 1.25 m, kedalaman 13 m, kecepatan angin 5 knot dan dekat dengan Pantai Padang Melang. Analisis teknis berupa perhitungan berat, perhitungan stablilitas, perhitungan trim, dan perhitungan freeboard. Kemudian dilanjutkan dengan mendesain lines plan, general arrangement, dan safety plan serta desain model 3D. Pada Tugas Akhir ini juga dilakukan analisis ekonomis dengan total biaya pembangunan senilai Rp37.943.604.270,89. dengan biaya operasional sebesar Rp7.647.678.982,05/tahun. Dilakukan perhitungan dan didapatkan nilai Net Present Value (NPV) sebesar Rp45.205.683.946,57, Internal Rate of Return (IRR) senilai 20%, dan Payback Period selama 7 Tahun 0 Bulan 14 Hari

    From the editor's desk: Common errors in submission of case reports

    Get PDF
    AbstractCase reports remain an invaluable resource in the literature, and they continue to serve an equally important role in scientific advancement. They record discoveries, report the unexpected, and spark further research. Preparation of a case report can be a great learning experience, especially for medical students, residents, and young physicians. It serves as an excellent introduction to academic writing, familiarizing them with all aspects of publishing, from a structured case presentation and literature review to submitting and revising a manuscript. It can also stimulate an interest in a specific topic and gradually lead to more involved and complex academic endeavors

    Estimating the Total Economic Impact of Black Bear Peeling in Western Oregon Using GIS and REMI

    In parts of the Pacific Northwest, black bears emerge from winter dens with depleted fat reserves and feed on mature conifers by stripping bark and consuming sugar-rich sapwood. Peeling by bears affects commercial conifers through direct loss of the tree or degraded log quality at stand harvest. Bears generally peel trees from 15-30 years old in intensively managed forests until preferred foods such as fruits and berries are available, and a single bear can peel several trees per day. Dying trees have a signature red canopy and are detected in annual aerial forest health surveys; however, trees that scar over peeling are not detected by aerial surveys. Previous studies reported results of damage summaries for northwest Oregon from flights, adjusted for bias; however, they offered no estimates of economic impact. Using landowner survey data, another study estimated an annual timber loss to bears at approximately 11.5millionacrosspartofwesternOregon.Whileinformative,theseestimatesusedbroadassumptionstoderiveprimaryimpactsanddidnotaddresssecondaryimpacts.Weusedaerialhealthsurveys,thenationallandcoverdatabase,andtheRegionalEconomicModelsInc.(REMI)PI+modeltoestimatetheprimaryandsecondary(indirectandinduced)impactsofbearpeelinginwesternOregon.Becausetheaccuracyandprecisionofaerialestimates(i.e.,percentageofdeadtrees/polygon)wasunknown,wecalculated4scenariosofloss:111.5 million across part of western Oregon. While informative, these estimates used broad assumptions to derive primary impacts and did not address secondary impacts. We used aerial health surveys, the national land cover database, and the Regional Economic Models Inc. (REMI) PI+ model to estimate the primary and secondary (indirect and induced) impacts of bear peeling in western Oregon. Because the accuracy and precision of aerial estimates (i.e., percentage of dead trees/polygon) was unknown, we calculated 4 scenarios of loss: 1%, 10%, 30%, and 100% loss. Under these scenarios, black bear damage to commercial forests negatively impacted Oregon’s gross domestic product between 0.9-$89 million annually, and resulted in an annual loss of between 11 and 1,012 jobs in the state. We will explain our methodology in this study as well as current efforts to improve the accuracy and precision of damage estimates, and ultimately our understanding of the economic impacts of black bear peeling

    A two-species continuum model for aeolian sand ripples

    Get PDF
    We formulate a continuum model for aeolian sand ripples consisting of two species of grains: a lower layer of relatively immobile clusters, with an upper layer of highly mobile grains moving on top. We predict analytically the ripple wavelength, initial ripple growth rate and threshold saltation flux for ripple formation. Numerical simulations show the evolution of realistic ripple profiles from initial surface roughness via ripple growth and merger.Comment: 9 pages, 3 figure

    What is the right level of spending needed for health and care in the UK?

    The health and care sector plays a valuable role in improving population health and societal wellbeing, protecting people from the financial consequences of illness, reducing health and income inequalities, and supporting economic growth. However, there is much debate regarding the appropriate level of funding for health and care in the UK. In this Health Policy paper, we look at the economic impact of the COVID-19 pandemic and historical spending in the UK and comparable countries, assess the role of private spending, and review spending projections to estimate future needs. Public spending on health has increased by 3·7% a year on average since the National Health Service (NHS) was founded in 1948 and, since then, has continued to assume a larger share of both the economy and government expenditure. In the decade before the ongoing pandemic started, the rate of growth of government spending for the health and care sector slowed. We argue that without average growth in public spending on health of at least 4% per year in real terms, there is a real risk of degradation of the NHS, reductions in coverage of benefits, increased inequalities, and increased reliance on private financing. A similar, if not higher, level of growth in public spending on social care is needed to provide high standards of care and decent terms and conditions for social care staff, alongside an immediate uplift in public spending to implement long-overdue reforms recommended by the Dilnot Commission to improve financial protection. COVID-19 has highlighted major issues in the capacity and resilience of the health and care system. We recommend an independent review to examine the precise amount of additional funds that are required to better equip the UK to withstand further acute shocks and major threats to health
