Kriteria Bangunan Hijau Dan Tantangannya Pada Proyek Konstruksi Di Surabaya

Sektor bangunan memiliki dampak besar tidak hanya pada kehidupan ekonomi dan sosial, tetapi juga pada lingkungan alam yang dibangun. Meskipun penerapan bangunan hijau dapat mengurangi kerusakan lingkungan, namun tidak semua bangunan baru didisain dan dibangun dengan menerapkan konsep bangunan hijau. Hal ini disebabkan karena penerapan konsep bangunan hijau tidak mudah, dan disamping itu terdapat tantangan yang menghambat penerapan konsep bangunan hijau. Penelitian ini dilakukan dengan cara penyebaran kuesioner yang ditujukan kepada kontraktor grade 6 & 7, konsultan grade 4, owner, dan pemerintah. Selanjutnya semua kuesioner yang berhasil dikumpulkan akan diolah dengan menggunakan analisis deskriptif dan one way Analysis of Variance (Anova) dengan program SPSS. Hasil dari analisis mean dibandingkan dengan studi lapangan berupa wawancara dengan narasumber kontraktor, konsultan, dan owner sebagai pembanding dari hasil kuesioner. Dari hasil analisis didapatkan bahwa kriteria yang paling mudah yaitu pencahayaan alami dan ventilasi, pemandangan keluar gedung, dan introduksi udara luar. Sedangkan tantangan terbesar yaitu kurangnya pendanaan dalam membangun bangunan hijau, kurangnya perhatian publik terhadap bangunan hijau, dan kurangnya komitmen dari pimpinan administrasi untuk melindungi lingkungan

Long-term trajectory and temporal dynamics of tropical peat subsidence in relation to plantation management and climate

Disentangling land-use and climatic influences on peat subsidence, and establishing the long-term trajectory of subsidence, are necessary to determine the future economic and environmental sustainability of managed peatland landscapes. While many peatlands in temperate regions such as Europe have been drained for centuries, those of Southeast Asia have mostly been drained for agriculture and forestry practices within the last 30 years. These areas are subsiding rapidly, but few long-term subsidence records exist, and it is unclear whether currently high subsidence rates will be maintained in future. Furthermore, large-scale climate fluctuations associated with the El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) exert a strong year-to-year influence on rainfall rates, affecting water table depth dynamics in both managed and intact peatlands. In this study, we analysed data collected over more than a decade of subsidence measurements from over 400 plantation and forest plots in Sumatra, Indonesia, including a unique set of 62 sites that have been continuously monitored since 2007. We show that spatial and temporal variations in subsidence rates are primarily determined by water table depth. We also find evidence of declining subsidence rates as a function of time since initial drainage, consistent with previous instrumental records from high-latitude peatlands and recent satellite data from tropical peatlands. Subsidence rates over the study period were strongly affected by the large ENSO/IOD-linked drought event in 2015–16, which caused an acceleration of subsidence across all sites. In plantation areas, we estimate that this climate perturbation caused around 14 % of subsidence observed over a twelve year period. At interior forest sites this rose to 32 %, and we found little evidence of ecosystem recovery to the end of 2018. This raises the possibility that repeated extreme droughts in the region could lead to long-term degradation of peat swamp forest ecosystems

Baseline characteristics of patients in the reduction of events with darbepoetin alfa in heart failure trial (RED-HF)

<p>Aims: This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other outcomes.</p> <p>Methods and results: Key demographic, clinical, and laboratory findings, along with baseline treatment, are reported and compared with those of patients in other recent clinical trials in heart failure. Compared with other recent trials, RED-HF enrolled more elderly [mean age 70 (SD 11.4) years], female (41%), and black (9%) patients. RED-HF patients more often had diabetes (46%) and renal impairment (72% had an estimated glomerular filtration rate <60 mL/min/1.73 m2). Patients in RED-HF had heart failure of longer duration [5.3 (5.4) years], worse NYHA class (35% II, 63% III, and 2% IV), and more signs of congestion. Mean EF was 30% (6.8%). RED-HF patients were well treated at randomization, and pharmacological therapy at baseline was broadly similar to that of other recent trials, taking account of study-specific inclusion/exclusion criteria. Median (interquartile range) haemoglobin at baseline was 112 (106–117) g/L.</p> <p>Conclusion: The anaemic patients enrolled in RED-HF were older, moderately to markedly symptomatic, and had extensive co-morbidity.</p&gt

Analysis of Institutional Ownership, Managerial Ownership, Profitability, Company Growth, Asset Structure Versus Debt Policy on Real Estate and Building Construction on the Indonesia Stock Exchange 2016-2019

This research is a study to determine the analysis of institutional ownership, managerial ownership, profitability, company growth, asset structure on debt policy. The population used is all real estate and building construction companies listed on the Indonesia Stock Exchange. The sample was selected by purposive sampling technique. This study uses secondary data and is tested using the analytical method used is multiple linear regression, the coefficient of determination is tested simultaneously (F-Test) and partially (T-Test). The results of the regression analysis show that the effect of the independent variables (institutional ownership, managerial ownership, profitability, company growth, asset structure) in explaining the dependent variable (debt policy) is 52.6%. The results show that profitability and asset structure partially affect debt policy, while institutional ownership, managerial ownership, and asset structure partially do not affect debt policy. The results show that institutional ownership, managerial ownership, profitability, company growth, asset structure simultaneously affect debt policy
