Abstract

Water control technology aims to provide a sufficient water supply to avoid overflow. An automatic valve sluice gate made from fiberglass is preferred for water control in tidal agriculture. The mechanical valve sluice gate model can automatically release and close water discharge at a precise angle to optimize water control in tidal agriculture. The advantage of this sluice gate design is its utilization of the difference between upstream and downstream water levels on the sluice gate. A sluice gate design with a slope angle of 15 ° is recommended for tidal agriculture. The upstream water level should reach a height of 1.67 m for the sluice gate to open, while the downstream side should be at 0.82 m. The sluice gate will automatically open if the water level difference is 0.85 m in height and close if there is no water level difference. It is known that the flood level from the ground is 1 m to 2 m. It is suggested to elevate the land to prevent flooding for residents.

Abstract

As one of the coastal areas, Mendalok, Sungai Kunyit sub-District, Mempawah Regency faces problems caused by coastline changes such as administrative area changes and damage to the mangrove forest ecosystem in the region. The objective of this study is to determine the process of wave conversion leading to coastline changes and to determine the potential for coastline changes from 2021 to 2031. Coastline change modelling analysis is performed with the CEDAS-NEMOS application. The results showed that the wave movement pattern was dominated by the southwest and west with a significant wave height averaging 1.36 meters and the waves were broken with a wave angle of 208.09o. The result of the coastline change modelling shows that coastline changes are more dominant in the study area when experiencing abrasion with calibration values of K1 0.5 and K2 0.25. Predicting the coastline changes that will occur from 2021 to 2031 shows that the coast with the greatest abrasion value of 31.83 meters and some accretion is more dominant with the greatest accretion value of 11.21 meters.

Abstract

Flood occurs when water overflows its banks due to inadequate channel capacity. Flooding typically results from too much precipitation, which prevents the channel from handling the water flow and results in a deluge. Pontianak City frequently faces severe and protracted flooding when it rains. Both high rainfall and rising sea levels, which impact the Kapuas River, might result in flooding. This argument states that this study was done to anticipate sea level rise for the next six years, which will impact Pontianak City's water flow height using tidal data from Pontianak's Climatology Maritime Station from 2016 to 2021. The average rate of sea level rise, calculated using the least squares approach, is 1.579 cm/year. With an increase rate of 0.017 cm/year, the average sea level rise forecast for the Kapuas River for the next six years is 1.789 cm. It will be necessary to reduce floods in the future to avoid the effects of water flow.

Abstract

The Kapuas River is a very important water transportation route in West Kalimantan, crossing 5 districts and 1 city. The problem that occurs in the shipping lane on the Kapuas River is the accumulation of severe sediment at the mouth of the estuary. This becomes an obstacle for ships with large loads to sail, for this reason, this research was carried out. The purpose of this study was to determine the dominant direction of waves and sediment transport. This study was calculated using the CERC (Coastal Engineering Research Centre) method and using secondary data. It was found that the dominant wave direction came from the North (N) direction with an incidence percentage of 22.496%. Percentage of occurrence from the Northwest (NW) direction is 12.145%, from the West (W) direction is 6.253%, and from the Southwest direction (SW) is 11.724%. While the amount of sediment transport from the Northwest is -393062.1306 m3/year with the characteristics of the sediment being clay, from the West it is -250.1672 m3/year with the sediment characteristics being silty clay and from the Southwest, it is 579090.2782 m3/year with sediment characteristics of silty clay. The results of the sediment calculation have negative results which indicate that there is no sediment transport from the Northwest and West, but the sediment is deposited. For this reason, it is necessary to carry out appropriate handling of these problems to reduce sediment build-up in the study area.

Abstract

The Pontianak Kapuas River has a narrow shipping lane with a one-way route system. To reduce the danger in sailing in the shipping channel, a navigation tool is needed in the form of cardinal buoy. Based on the information obtained, there is a cardinal buoy 1 that has collapsed and endangered the shipping lanes. So it is necessary to carry out a hydrographic-bathymetric survey using the Multibeam Echosounder (MBES) technology. This survey aims to identify the coordinates and direction of the cardinal buoy object. The sounding method is a method used to obtain water depth data in the survey area. After processing the data, it was found that the coordinates of the cardinal buoy that collapsed were 0°4'29" N - 109°10'02" E and experienced a position shift of around ± 38 meters. The cardinal buoy that have been found do not block the shipping lanes because of their position as far as 240.39 meters from the shipping lanes. For this reason, the cardinal buoy that has collapsed does not need to be lifted, only a marker bouy is given,

Abstract

This study aims to analyze the design and stability of the Galaherang tourist vessel operating on the Kapuas River, Pontianak, using Maxsurf software. The Galaherang is a river-based passenger vessel designed to accommodate approximately 97 passengers and 4 crew members. The analysis includes hull form modeling using Maxsurf Modeler and stability simulation using Maxsurf Stability. The study encompasses hydrostatic calculations, equilibrium analysis, and large angle stability assessment. The results show that the vessel has principal dimensions of LOA 21 m, LWL 17.6 m, beam 5 m, depth 3 m, total height 8 m, and draft 1.61 m. The vessel’s transverse metacentric height (GMt) is 0.957 m under full load conditions. The righting arm (GZ) curve reaches a maximum of 0.523 m at a heeling angle of 45.5°, with an area under the curve of 71.583 m·deg for the 0–30° range. Simulations under dynamic conditions, such as passenger crowding and turning, result in heel angles ranging from 7.5° to 10°, which remain within safe limits. The design complies with the minimum stability criteria set by IMO Resolution A.749(18) Chapter 3 and the BKI standards for passenger vessels, meeting requirements for initial stability, large-angle stability, and longitudinal balance.
