Abstract

Tanjung Perak Surabaya, sebagai salah satu Pelabuhan yang sangat ramai berpotensi mengalami pendangkalan yang disebabkan oleh pengendapan atau penumpukan sedimen suspense maupun material sedimen lainnya yang terbawa oleh arus yang menuju masuk ke Pelabuhan. Tujuan Penelitian ini adalah untuk mengetahui Pola sebaran sedimen. Data penelitian meliputi data utama dan data pendukung, data utama berupa sampel sedimen grab, sampel sedimen trap, peta batimetri, data pendukung berupa arus, pasut, dan konsentrsi TSS. Metode yang digunakan dalam penelitian metode sampling dan menganalisis hasil sampel sedimen di laboratorium. Hasil dari 9 stasiun pengamatan di Pelabuhan Tanjung Perak menunjukan Jenis sedimen yang didominasi oleh Silt Clay Loam,, nilai konsentrasi TSS 0.32-0.07 (g/l). Kecepatan laju sedimentasi yang terakumulasi berkisar antara 0.124-1.233(g/ml/hari). Overlay peta batimetri menunjukkan adanya sebaran endapan sedimen di area pintu masuk Pelabuhan tanjung Perak(tengah).

Abstract

Pesisir Wedung merupakan wilayah perairan memiliki kondisi dinamis. Hal ini sangat terkait dengan kondisi oseanografi yang terjadi dan adanya groin dilokasi tersebut. Penelitian ini bertujuan untuk menganalisis perubahan garis pantai di Pantai Wedung ditinjau dari citra satelit dan menganalisis potensi gelombang dalam mempengaruhi perubahan garis pantai di lokasi groin pesisir Wedung. Metode yang digunakan terdiri atas beberapa tahapan penelitian yaitu: pengolahan data angin, peramalan tinggi dan periode gelombang, tinggi dan kedalaman gelombang pecah metode menurut CERC, memodelkan gelombang dan arus menggunakan Software Surface Water Modeling System. Kondisi garis pantai hasil citra akresi seluas 334 m2 dan abrasi seluas  881 m2. Pola perubahan garis pantai disekitar groin cenderung terjadi akresi disebelah Timur groin dan abrasi di Barat groin karena kecepatan arus sejajar pantai dari arah Timur lebih tinggi dari arus sejajar pantai arah Barat, yakni 1 m/s yang dibangkitan gelombang pecah.

Abstract

The coastal region is characterized by dynamic changes in its coastline, which can be attributed to various factors. However, the main causes of change along the Gresik coast have yet to be thoroughly studied. Therefore, this research aims to examine the patterns of coastline change along the Gresik coast around the Madura Strait and the influence of wind-generated waves on them. Specifically, the study focuses on four coastal zones: Ujung Pangkah, Sidayu, Bungah, and Manyar districts. The research utilizes satellite imagery and geographic information systems (GIS) as well as methods for calculating ocean waves to analyze the coastline change patterns. The study also examines the impact of ocean wave energy on coastal abrasion and accretion. The findings revealed that the accretion rate in the study area was higher than the erosion rate. The accretion in the coastal area of Gresik is attributed to the flow of the Bengawan Solo River, which carries sediment from upstream. The accretion and abrasion areas for the entire period from 2002 to 2019 were 1063.16 ha and 425.23 ha, respectively. The study also found that the mangrove areas exhibit a higher rate of accretion than abrasion, indicating their potential as a reliable indicator of the effects of sea level rise resulting from global warming.This study revealed that the northern part of Ujung Pangkah District and Bungah District experienced the highest abrasion patterns, whereas no abrasion was observed in Sidayu District. Between 2002 and 2019, the abrasion areas in Ujung Pangkah and Bungah districts totaled 243.96 ha and 178.29 ha, respectively. Wind-generated waves were likely the primary cause of the abrasion in these areas, though other factors may also have contributed to coastline changes. It is essential to consider these factors for effective coastal management in the region.

Abstract

Indonesia is the world's largest island nation with many islands and more seas than land. Because of the size of the Indonesian sea, oceanographic science is needed. Oceanographic learning involves the study of the underwater depths of the batimetric sciences. Batimetric science is crucial because it studies underwater depth. Batimetric processes in Indonesia today generally employ large vessels with manual control, resulting in the skill required of drivers at risk for obtained track data. With the problem, it has been designed to disrupt the autonomous control system with a pid waypoint system that would provide stable direction for the ship. The control system USES the arduino microcontroller which is used for processing data. The data obtained are data coordinates obtained from the GPS and the ship's navigation data obtained from the compass sensors. The data obtained will be processed and applied to pid methods. Of the pid process can be generated the degree degree required to power the servo motor connected to the ship's rudder. In this research USES four coordinate points of starting point, first goal point, second point of destination, and third point of goal. Once it reaches the third point of destination, the ship will return to its starting point. From the results of the testing done, the result is a kostanta pid score of KP =8, ki =5, kd = 3.5. Tests enabled the system that kept the ship's course steady as it should. So the ship goes on track.
