Abstract

Sea level is one of ocean properties that needed to be observed. Sea level observation will give information about osean tides and tides datum. As technology became more reliable, people can develop new instrument easily. Recently, open source microcontroller “Arduino” became popular and lot of people using it to develop what we call “low-cost” instrument. But, there are several disadvantages if we build instrument directly. Simulation phase must be done before manufacture instrument. This phase will help to decrease cost and time. In this paper, we will describe the concept, algorithm, and simulation phase in manufacturing Low Cost Ocean Tides Monitoring Instrument.

Abstract

Tides observation conducted for these purposes such as real-time depth of water, determination mean sea level and other tidal datums to establish a system of tidal benchmarks and data for production of tide and tidal current predictions. Center for Marine and Coastal Mapping – Geospatial Information System used water level and tides data mainly to correct the water depth measurement to chart datum. This study uses sea level observation data conducted from 20th February 2018 until 4th April 2018 at Marina Batavia, Jakarta. This study found that tidal types at this location is mixed diurnal using formzahl number. Astronomical and shallow water possible constituent were derived from the harmonic analysis. Fourier analysis gives clearly visual interpretation in frequency perspective. Several constituents inseparable because of short duration records.

Abstract

Coastline Modeling Accuracy Assessment Developed By Using from Multi-Source Data. The coastal regions need to be developed because many big cities in Indonesia are located in these areas. However, it is crucial to determine the distance from the beach that is safe as the requirement for development along the coastal zone. The term of the beach is very closely affiliated with the coastline. The method of determining the coastline continues to be developed to fulfill the many needs related to the coastline. The coastline has a dynamic position. The land contour along the coast and the tide's state become several things that affect the coastline. Therefore, a dynamic model is required to define coastline positioning because both conditions are easy to change. The coastline determination from multi-source data modeling using DEM results is rarely done. In this study, coastline determination uses land height contours combined with sea depth contours and uses Mean Sea Level (MSL) value for vertical reference using the DEM model. The model's accuracy is tested by comparing the coastline delineation model and the Geospatial Information Agency coastline to test the DEM model generated before determining the coastline using this model as the reference. Based on this study, the compared shoreline models and delineation have gaps. This gap might be influenced by the data source, the model's resolution, and the data collection method.

Abstract

This study investigates the precision of coordinate positioning using Global Navigation Satellite System (GNSS) technology, focusing on GNSS Neo Series modules and the GSM SIM 7000E module. The research aims to address the lack of comparative studies evaluating these GNSS receivers simultaneously. A field test spanning 24 hours was conducted to collect data on satellite acquisition and Horizontal Dilution of Precision (HDOP). The GNSS systems were deployed in a controlled environment at the Class I Meteorological Station Hang Nadim, Batam. The system developed comprised GNSS modules (Neo 6M, Neo 7M, Neo 8M, and GSM SIM 7000E), an ESP32 microcontroller, Arduino UNO, and a Micro SD shield module. Data processing involved converting coordinates to meters and calculating longitude and latitude errors. Root Mean Square Error (RMSE) analysis and one-way ANOVA were performed to assess accuracy and compare the GNSS receivers. Results indicate that the GSM SIM 7000E demonstrated superior satellite acquisition, leading to higher accuracy in coordinate positioning compared to the Neo Series modules. The study also identified optimal data collection times for accurate dispersion. These findings provide valuable insights into selecting and deploying GNSS receivers, enhancing performance in location-based services and scientific applications.

Abstract

Tides are the rising and falling movement of sea level caused by the gravitational force of celestial bodies such as the moon and sun on the mass of seawater on earth. The aim of this research is to compare the use of time series of harmonic constant parameters obtained from tidal data stored in the tool using the admiralty method. Research activities were carried out at the international port of Dompak Island, Tanjungpinang City, Riau Islands. This tidal data is analyzed by admiralty. This method is used to analyze harmonic constants and identify patterns and sea level levels. Based on the results obtained, the type of tide in Tanjungpinang waters is a mixed tide (single dominant) with an F value of 2.01 to 2.07. The sea level elevation values "‹"‹obtained (MSL) from each time series ranged from 75.83 cm to 76.60 cm, (MHWL) ranged from 97.17 cm to 98.24 cm. Then (MLWL) ranges from 58.77 cm to 59.39 cm. Meanwhile, (HHWL) ranges from 153.98 cm to 154.73 cm, and (LLWL) ranges from -2.77 cm to -1.96 cm. With a confidence interval of 5 percent, is obtained. The difference in each time series seen from the data (MSL) is 7cm. Therefore, Tidal data from each time series has no significant differences.
