Readiness of the Haji Abdoel Madjid Regional General Hospital Batanghari Jambi to Deal Disaster

Disasters are events caused by events or a series of events caused by natural or non-natural. During the period from January to May 2021, there were 1,185 disasters that occurred in Indonesia such as floods, tornadoes, landslides, forest and land fires, earthquakes, tidal waves and droughts. This study aimed to analyse the preparedness of the Haji Abdoel Madjid Batang Hari Regional General Hospital (RSUD HAMBA) Jambi (facing disasters and the COVID-19 pandemic). The research method uses a mix method approach, using the Hospital Safety Index (HSI) forms. The HAMBA Hospital included earthquakes, strong winds, fires, and the COVID-19 pandemic. The struktural safety assessment got an index score of 0.69, non-struktural safety was 0.67, and emergency and disaster management safety got an index score of o.63. Overall, HAMBA Hospital received a safety index of 0.67 which was included in the "A" classification which indicates that HAMBA Hospital is ready to face the COVID-19 disaster and pandemic. HAMBA Hospital is expected to strengthen emergency and disaster management, renovation and addition of rooms and facilities must follow applicable hospital building safety standards.

Indirect estimation of turbulent mixing in western route of Indonesian throughflow

The Indonesian Throughflow (ITF) via its western path conveys mainly North Pacific water origin with Smax thermocline water and Smin intermediate water from its entry portal in Sangihe-Talaud arcs to the main outflow straits in Lombok, Ombai and Timor passage. Along its route, the throughflow water characteristics transforms significantly due to strong diapycnal mixing forced by internal tidal waves interaction along complex topography such as passages, sill, straits, and shallow islands chains. This paper reports a brief estimate of turbulent mixing profiles in Sangihe chains, and Makassar Strait. The CTD dataset are obtained from the year of maritime continent (YMC) Cruise in August 2019 on board the R.V. Baruna Jaya I. The Thorpe method is used to analysis dissipation energy ( ε ) and vertical diffusivity (Kz ) from CTD dataset. It is shown that the highest ε epsilon 5.87 × 10−7 Wkg −1 and Kz 4.42 × 10−3 m2s 1 are found in the Sangihe area. In Labani Channel and Dewakang Sill the averaged vertical diffusivity is much weaker at the order of 10−4 m 2s1. Thus, Sangihe Chains station have the highest values compared to other stations at depth 950-1000 meters.

Transformation of baroclinic tidal waves in the conditions of the shelf of the Far Eastern seas

This work is devoted to the study of the regimes of transformation of baroclinic tidal waves under the conditions of the Far Eastern seas within the framework of a fully nonlinear numerical model. Two sections were selected to study the features of wave dynamics – in the Sea of Okhotsk (Sakhalin Island shelf) and in the Bering Sea (near Cape Navarin). On the basis of the performed calculations, regional and seasonal features of the transformation of baroclinic waves and the structure of the flow induced by them were revealed. It is shown that the dynamics in the winter season is less intensive. The rotation effect on the formation of solibore in the studied conditions is analyzed. The obtained estimates of wave amplitudes and velocities are consistent with the published data of field observations in the Sea of Okhotsk. For the Bering Sea, the conditions are shown to be favorable for the generation of intensive internal waves, which indirectly confirms the hypothesis of influence of such waves on the formation of underwater sand dunes.

Internal solitary waves in the Northwest Sumatra Sea-Indonesia: from observation and modeling

>The southern Andaman waters has been well known as one of the strongest generating and propagating area of internal solitary waves (ISWs), generated by semidiurnal barotropic tidal currents that impinge submarine ridge offshore western Weh. This study aims to investigate sea surface features of internal tides and tidal current around the submarine ridge and adjacent Weh-Aceh waters, derived from satellite imagery datasets (January-May 2018) and CROCO model-output datasets. The results show that sea surface signatures of ISWs are characterized by a strong radar signal backscattering of a dense ripple package in the generating area and two groups of ISWs arch in the propagating area, where the distance of the package groups and wavelengths vary 60-80 km and 9-163 km, respectively. Observed ISWs in March 2018 was 31. The satellite and model datasets suggest that generating area of internal waves is confined over the Breuh ridge. Here, the very strong semidiurnal (M2) barotropic tidal currents of 0.5-5.0 m/s are observed. During high-tide, amplified barotropic tidal currents acrossing the ridge flow partly southeastward into the Weh-Breuh passage. The model suggests that generating internal tidal waves over the ridge are manifested by strong vertical perturbation of isopycnal and current stratifications in the Lee-waves area.

Generation Mechanism of Tidally-driven Whirlpools at A Narrow Strait in An Estuary

This study investigates the generation mechanism and influence of the whirlpools in the Naruto Strait on the surrounding marine environment using state-of-the-art high-resolution numerical ocean circulation modeling in a quadruple nested configuration. The Naruto whirlpools is recognized as an extraordinary seascape that the local governments and the citizens seek to register as a world natural heritage site. We found that the pronounced pressure gradient force associated with the meridional surface elevation difference was induced by a phase difference of two bifurcating major tidal waves. These waves originate from the Kitan Strait, and ultimately produce intense tidal currents at the Naruto Strait. One branch of the tidal waves propagates counter-clockwise along Awaji Island through the Akashi Strait, while the other occurs directly from the Kii Channel. As such, the whirlpool emerges as a large number of sub-mesoscale eddies, primarily due to the horizontal shear instability of tidal currents energized at the narrow topography between two headlands that extend into the strait. A dipole of overturning vertical circulations appears underneath the whirlpools with convergent downward transport at the strongest tidal current near the center of the strait; this causes efficient vertical mixing. This three-dimensional non-linear mixing promotes a time-averaged southeastward mass transport that extracts water and materials from the Harima-nada Sea into the Kii Channel.

Spatial Modeling Of Coastal Flood Due To The Fishpond To Tidal Waves In Bengkalis, Indonesia

Bengkalis Island is one of the small islands in Riau Province, which is located on the east coast of Sumatra. It is separated from the island of Sumatra and is in the middle of the Malacca Straits, which is directly facing the ocean and vulnarble to affected by the enormous energy of the tidal waves that propagate on the land surface. Make coastal areas inundated by tidal floods. This is exacerbated by the conversion of mangrove land into Fishponds, which is carried out en masse to support the economy of the Bengkalis community. The degradation of mangrove land, it is also exacerbated by global warming that causes rising sea level. it very vulnerable to coastal areas, especially in the research area. This research method uses geospatial modeling, using tidal data from the geospatial information agency (BIG), land cover image classification, soil surface roughness index, and flood scenarios. The results of this study we found that many coastal areas are prone to tidal flooding. At various maximum heights, there are variations in the distribu-tion of tidal flooding. For the final decision, we use the worst scenario using the highest tidal discharge, which is 3.4 meters. This simulation model inundated more than 74% of use in coastal areas. Not only that; many, agricultural areas were also affected by this tidal flood. We developed this simulation for analysis of losses due to the tidal wave, and we, found a loss index that reached 62% of the total loss of residential areas, including the loss of infrastructure and residen-tial buildings.
