Abstract

Kawasan pesisir Parangtritis adalah salah satu tujuan wisata pantai yang signifikan bagi Daerah Istimewa Yogyakarta (DIY). Aktivitas pariwisata di Parangtritis dapat dibagi menjadi dua bagian, yaito aktifitas wisatawan di wilayah pasang surut (swash zone) dan pembangunan fasilitas pendukung bagi wisatawan di wilayah darat (backshore). Perubahan garis pantai disebabkan oleh faktor-faktor seperti angin, gelombang laut, dan arus laut. Tujuan dari penelitian ini adalah untuk mengetahui perubahan garis pantai yang terjadi di wilayah Pantai Parangtritis serta hubungannya dengan pasang surut dan gelombang laut. Pemantauan perubahan garis pantai dilakukan metode Digital Shoreline Analysis System (DSAS). Metode perhitungan perubahan garis pantai yang digunakan pada DSAS yaitu metode Net Shoreline Movement (NSM), Shoreline Change Envelope (SCE) dan End Point Rate (EPR). Pengamatan perubahan garis pantai mengambil rentang waktu selama 5 tahun menggunakan data tahun 2017, 2018, 2019, 2020, dan 2021. Pada hasil penelitian ditemukan fakta bahwa terjadi abrasi dan akresi pada wilayah Pantai Parangtritis. Abrasi terjadi pada daerah yang terdampak ombak secara tinggi, tanpa adanya pemecah ombak. Akresi terjadi pada wilayah dengan kemiringan landai dengan gelombang lebih lemah. Akresi tertinggi tercatat sebesar 63.31 meter, dan abrasi tertinggi tercatat dengan angka -63,35 meter. Faktor hidrooseanografi seperti gelombang yang datang menuju pantai akan mengikis dan berpengaruh terhadap berubahnya garis pantai dan besarnya angkutan sedimen. Hal tersebut didukung dengan tinggi gelombang pada daerah tersebut adalah 2,5meter dengan rata-rata periode 10,81 detik.   The coastal area of Parangtritis is one of the significant beach tourism destinations in the Special Region of Yogyakarta (DIY). Tourism activities in Parangtritis can be divided into two parts, namely tourist activities in the swash zone and the development of supporting facilities for tourists on the backshore. Changes in the coastline are caused by factors such as wind, sea waves, and ocean currents. The purpose of this research is to understand the changes in the coastline that occur in the Parangtritis Beach area and their relationship with tides and sea waves. Monitoring of coastline changes is conducted using the Digital Shoreline Analysis System (DSAS). The methods used for calculating changes in the coastline in DSAS are Net Shoreline Movement (NSM), Shoreline Change Envelope (SCE), and End Point Rate (EPR). The observation of coastline changes spans a period of 5 years, using data from 2017, 2018, 2019, 2020, and 2021. The research findings show that there were both abrasion and accretion processes in the Parangtritis Beach area. Abrasion occurred in areas heavily impacted by high waves without the presence of wave breakers. Accretion took place in areas with gentle slopes and weaker waves. The highest accretion recorded was approximately 63.31 meters, while the highest erosion reached -63.35 meters. Hydrooceanographic factors, such as waves approaching the coast, erode the shoreline and influence the change in coastline and sediment transport. This is supported by the fact that the wave height in the area is 2.5 meters with an average period of 10.81 seconds.

Abstract

Sea Turtles are a type of reptile that predominantly inhabit marine environments, and their populations have experienced a significant decline due to various factors such as natural habitat destruction, marine pollution, predation, and commercial hunting. Conservation efforts are crucial to maintaining the sustainability of turtle populations. The Sea Turtle Conservation Area in Malang Regency, known as Bajulmati Sea Turtle Conservation (BSTC) Malang, has committed to caring for adult turtles, hatching eggs, and nurturing turtle hatchlings. However, these conservation activities have not been fully optimized, particularly in monitoring nesting turtles, rescuing eggs, and addressing turtle diseases. This Community Service Initiative aims to provide knowledge and skills to the conservation area managers related to monitoring, rescuing, and treating turtle diseases. The goal is to enhance the number of saved turtle eggs and improve their survival rate.

Abstract

Hidrografi dan batimetri menyediakan informasi kedalaman dan bentuk dasar perairan yang sangat penting bagi navigasi, perencanaan pelabuhan, rekayasa pantai, dan tata ruang laut, terutama pada perairan dinamis dan keruh seperti Kabupaten Cilacap yang berbatasan langsung dengan Samudera Hindia. Penelitian ini bertujuan menganalisis akurasi data batimetri Satellite Derived Bathymetry (SDB) berbasis citra PlanetScope beresolusi tinggi dan membandingkannya dengan hasil pemeruman Single Beam Echosounder System (SBES). Data SBES dikumpulkan menggunakan Garmin 585 C, sedangkan kedalaman SDB diekstraksi dengan algoritma machine learning Generalized Additive Model (GAM). Data dibagi 75% untuk training dan 25% untuk testing, dan kinerja model dinilai menggunakan koefisien determinasi (R²) dan Root Mean Square Error (RMSE). Pengolahan data didukung perangkat lunak SIG dan penginderaan jauh seperti ArcMap, SNAP, ENVI, Global Mapper, RStudio, dan Surfer. Hasil menunjukkan SBES memiliki akurasi tinggi dan tetap menjadi rujukan utama pemetaan dasar perairan Cilacap. Sebaliknya, model SDB–GAM menghasilkan R² sebesar 0,35 dan RMSE 2,80 sehingga belum mampu merepresentasikan variasi kedalaman pada perairan. Nilai ini rendah karena perairan Cilacap yang keruh serta keberadaan sunglint pada citra menyebabkan distorsi reflektansi sehingga kedalaman hasil SDB sulit merepresentasikan variasi kedalaman aktual. Oleh karena itu, SDB – GAM belum direkomendasikan untuk pemetaan operasional di perairan keruh seperti Cilacap tanpa koreksi glint dan peningkatan strategi pemodelan, serta lebih tepat digunakan sebagai pemetaan awal pada kondisi perairan yang lebih jernih dan kedalaman terbatas.   Hydrography and bathymetry provide information on water depth and seabed morphology that is crucial for navigation, port planning, coastal engineering, and marine spatial planning, especially in dynamic and turbid waters such as Cilacap Regency, which borders directly with the Indian Ocean. This study aims to analyze the accuracy of bathymetric data Satellite Derived Bathymetry (SDB) derived from high-resolution PlanetScope imagery and compare it with obtained from Single Beam Echosounder System (SBES) sounding. SBES data were collected using a Garmin 585 C, while SDB depths were extracted using the Generalized Additive Model (GAM) machine learning algorithm. Data were split into 75% for training and 25% for testing, and model performance was evaluated using the coefficient of determination (R²) and Root Mean Square Error (RMSE). Data processing was supported by GIS and remote sensing software such as ArcMap, SNAP, ENVI, Global Mapper, RStudio, and Surfer. The results show that SBES provides high accuracy and remains the primary reference for seabed mapping in Cilacap waters. Conversely, the SDB–GAM model produces an R² of 0.35 and an RMSE of 2.80, indicating that it has not yet adequately represented depth variability in waters. This value is low because the murky waters of Cilacap and the presence of sunglint in the image cause reflectance distortion, making it difficult for the SDB results to represent actual depth variatons. Therefore, SDB-GAM is not yet recommended for operational mapping in murky waters such as Cilacap without glint correction and improved modeling strategies, and is more appropriately used for initial mapping in clearer waters and limited depths.

Abstract

Indonesia menempati posisi kedua setelah China sebagai penyumbang sampah terbesar di dunia. Sampah laut berdampak merugikan pada lingkungan, ekosistem, dan manusia. Penelitian ini bertujuan menganalisis distribusi dan karakteristik sampah laut di Pantai Pulau Gili Ketapang, Kabupaten Probolinggo. Metode yang digunakan meliputi pengambilan sampel manual dengan transek berukuran 5 × 5 m dan 1 × 1 m untuk mendapatkan data rinci mengenai jenis dan jumlah sampah, serta analisis citra Unmanned Aerial Vehicle (UAV)/Drone untuk memetakan distribusi sampah dalam cakupan area yang lebih luas. Hasil menunjukkan distribusi sampah laut bervariasi, dengan di Stasiun 3 memiliki kelimpahan sampah tertinggi dengan 38,91 item/m² untuk sampah makro dan 1,67 item/m² untuk sampah mega, yang dipengaruhi oleh aktivitas perikanan dan pelabuhan dan terendah di Stasiun 2 (0,91 item/m² untuk makro dan 0,10 item/m² untuk mega). Sampah plastik mendominasi dengan persentase 69,36%, terutama plastik sekali pakai. Penggunaan UAV/Drone terbukti efektif dalam memetakan distribusi spasial sampah laut secara luas, sementara sampling manual memberikan informasi lebih rinci mengenai jenis sampah. Integrasi kedua metode ini menghasilkan analisis yang lebih komprehensif dalam memahami pola persebaran sampah laut.   Indonesia ranks second after China as the largest contributor to marine debris globally. Marine debris has detrimental impacts on the environment, ecosystems, and human life. This study aims to analyses the distribution and characteristics of marine debris on the coast of Gili Ketapang Island, Probolinggo Regency. The methods used include manual sampling with transects measuring 5 × 5 m and 1 × 1 m to obtain detailed data on the types and quantities of debris, as well as Unmanned Aerial Vehicle (UAV)/Drone imagery analysis to map the debris distribution over a broader area. The results indicate that marine debris distribution varies, with the highest abundance at Station 3, recording 38.91 items/m² for macro debris and 1.67 items/m² for mega debris, influenced by fishing activities and the presence of a harbour, while the lowest was found at Station 2 (0.91 items/m² for macro and 0.10 items/m² for mega debris). Plastic waste dominated, accounting for 69.36%, primarily consisting of single-use plastics. The use of UAV/Drone proved effective in mapping the spatial distribution of marine debris on a large scale, while manual sampling provided more detailed information on debris types. The integration of both methods resulted in a more comprehensive analysis of marine debris distribution patterns.
