Biogeosciences, 17(2), (2020): 423-439, doi:10.5194/bg-17-423-2020.We use observations of dissolved inorganic carbon (DIC) and total alkalinity (TA) to assess the impact of ecosystem metabolic processes on coastal waters of the eastern Red Sea. A simple, single-end-member mixing model is used to account for the influence of mixing with offshore waters and evaporation–precipitation and to model ecosystem-driven perturbations on the carbonate system chemistry of coral reefs, seagrass meadows and mangrove forests. We find that (1) along-shelf changes in TA and DIC exhibit strong linear relationships that are consistent with basin-scale net calcium carbonate precipitation; (2) ecosystem-driven changes in TA and DIC are larger than offshore variations in >70 % of sampled seagrass meadows and mangrove forests, changes which are influenced by a combination of longer water residence times and community metabolic rates; and (3) the sampled mangrove forests show strong and consistent contributions from both organic respiration and other sedimentary processes (carbonate dissolution and secondary redox processes), while seagrass meadows display more variability in the relative contributions of photosynthesis and other sedimentary processes (carbonate precipitation and oxidative processes). The results of this study highlight the importance of resolving the influences of water residence times, mixing and upstream habitats on mediating the carbonate system and coastal air–sea carbon dioxide fluxes over coastal habitats in the Red Sea.This research has been supported by the King Abdullah University of Science and Technology (KAUST) (grant nos.

Faktor-faktor Penentu Dana Pihak Ketiga Bank Umum Syariah di Indonesia Tahun 2010-2017

Perkembangan dana pihak ketiga (DPK) Bank Umum Syariah (BUS) cenderung meningkat setiap tahun. Peningkatan ini diharapkan relevan dengan peningkatan kinerja keuangan USAhanya. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi dana pihak ketiga Bank Umum Syariah di Indonesia pada tahun 2010-2017. Metode analisis data menggunakan data panel dengan Random Effect Model (REM). Metode ini dipilih sebagai model terbaik berdasarkan Uji Chow, Uji Hausman, dan Uji Lagrange Multiplier. Data penelitian ini terdiri atas time series sebanyak 8 tahun dan cross section sebanyak 10 BUS. Sumber data penelitian diperoleh dari Bank Indonesia (BI) dan Otoritas Jasa Keuangan (OJK). Variabel independen dalam penelitian ini adalah bagi hasil, biaya promosi, dan jumlah kantor layanan. Hasil penelitian ini menunjukkan bahwa selama periode penelitian bagi hasil, jumlah kantor layanan, dan biaya promosi berpengaruh positif dan signifikan terhadap DPK BUS. Selain itu, hasil uji koefisien determinasi (R2) yaitu sebesar 0.869811. Hal tersebut menunjukkan bahwa sebesar 86.9811% variasi variabel dependen dijelaskan oleh variasi variabel independen. Untuk itu, BUS dapat mengkaji ulang penetapan tingkat bagi hasil, biaya promosi dan jumlah kantor layanan untuk mendorong capaian dana pihak ketiga secara progresif

The Effectiveness of the Disaster Resilient Village Program by the Local Disaster Management Agency

Disaster Resilient Village is a manifestation of the government's responsibility to provide protection to the community from the threat of disaster. The purpose of this research is to find out how effective the Disaster Resilient Village program by the Sukabumi City Regional Disaster Management Agency is. This research uses Duncan's theory. This research method uses qualitative research methods. Data collection techniques used observation, interviewing, and documentation techniques. Data validation methods used were source triangulation, technique triangulation, and time triangulation. The data analysis used is from Miles and Huberman, using data reduction, data presentation, and drawing conclusions and verification. The results of this study indicate that the Disaster Resilient Village program has been running in accordance with the established regulatory guidelines, but its implementation is still not running effectively, as there should be empowerment for the village to upgrade the criteria class of the village as stated in the Regulation of the Head of the National Disaster Management Agency Number 2 of 2012 regarding the implementation of the Disaster Resilient Village program, and the facilities and infrastructure are also not enough to maximize the workforce in supporting the Disaster Resilient Village program
