ABSTRACT Rupat Island is one of the islands included in the peat restoration planning area in Indonesia. This is caused by the large changes in land use on Rupat Island which can lead to disaster if the balance of Rupat Island's water balance is disturbed. This study aims to analyze the water balance of peatlands at the Peat Hydrological Unit (PHU) on Rupat Island to obtain surplus or deficit …
ABSTRACT Liquefaction is a process of changing soil properties when the solid state becomes liquid caused by cyclic loads as a result of an earthquake so that the pore water pressure increases, approaching and even exceeding the magnitude of the total pressure. Liquefaction occurs due to earthquakes that occur in the area. Tectonic earthquake is one type of earthquake that can trigger liquefac…
ABSTRACT West Papua is an eastern part of Indonesia that has great potential for earthquakes. Eastern Indonesia's seismic activity was triggered by geographical conditions in three major earthquake paths, namely the zone of the confluence of the Pacific and Papua New Guinea plates, the Sorong fault line and the Tarera – Aiduna fault (Naryanto, 2019). Bintuni Bay is one of the regencies i…
Permeability coefficient is one of the significant parameters in the calculation of seepage. Permeability also has a relationship with the physical properties of the soil. Permeability can be calculated and predicted in various ways. In this era, the use of artificial intelligence that is able to imitate the human nervous system has begun to be widely used in the geotechnical field, one of …

Suspended sediment concentracy measurement without affecting turbulence around the measurement area is still a key problem in sediment transport research. One of the potential methods to solve this problem is using acoustic backscattering method or using Acoustic Doppler Current Profiler (ADCP) instrument. The principle of this instrument is based on Doppler Effect, utilizing sound wave ping by…
Frequently high activity in the coastal area causes coastal morphological changes become unavoidable. Peat coast is easier to be ravaged than other coast with different material. Peat soil is susceptible because there is a big gap on peat particle size variation. Peat is cohesive in the inner layer but loose on the surface. Meanwhile, peat coastal surfaces are hit continuously by wave. Peat coa…
