Abstract

Blue swimming crab (Portunus Pelagicus) is a type of marine animal that has quite high economic value, so it is quite attractive to the surrounding community, especially the people in Sumenep Regency. The aim of this study was to find out the growth pattern of variations in carapace width and weight of blue swimming crab (Portunus Pelagicus) in the waters of the southern part of Sumenep Regency. This research was conducted in May 2023 in the village of Aengdake Sumenep. Retrieval of blue swimming crab data includes calculating the width of the carapace and the weight of the crab. The maximum width of the crab carapace is 16 cm while the maximum weight of the crab is 164 grams. From the calculation data for the width-weight relationship, it can be seen that the value of b is 0.74 where this value indicates that the growth pattern of blue swimming crab in the waters of Aengdake Village, Sumenep Regency with a sample of 100 crabs, shows a negative allometric growth pattern. So it is known that the growth in width is faster than the growth in weight.

Abstract

Mangroves are plants that live in muddy substrates, muddy sand, sand to tidal areas. These plants have important roles for marine organisms, carbon sequestration, as shoreline protectors from waves or erosion and sediment filters before entering the sea. The influence of human activity in the form of conversion of mangrove land to other forms or caused by natural disasters is a dangerous threat to the mangrove ecosystem. The magnitude of mangrove cover change is an important component so information is needed on changes in the spatial and temporal distribution of mangrove cover. This study aims to temporally analyze mangrove cover using high-resolution satellite imagery on the West Coast of Bangkalan Regency. This research uses secondary data in the form of Planetscope high-resolution satellite images from 2018 - 2023. The data will be processed to determine changes in mangrove area using Fv (Fractional Vegetation Cover). Calculation of the Fv (Fractional Vegetation Cover) value is done from the results of the minimum and maximum values of NDVI (Normalized Difference Vegetation Index). The results showed that there was a change in mangrove cover which was initially included in the FVC (Full Vegetation Coverage) class in 2022 with an area of 41.12 Ha to the HVC (High Vegetation Coverage) class with an area of 84.82 Ha in 2020. At the Arosbaya location, the highest Fv value occurred in 2019 with an area of 206.48 Ha. Reduction of mangrove area occurred in Sepulu and Arosbaya sub-districts due to land use change and sedimentation.

Abstract

The impact of climate change on coastal ecosystems has been a widely discussed topic in recent decades. The coastal ecosystem that is quite essential is mangroves. Community-based mangrove ecosystem management has actually been carried out in several places, but it is still not optimal. One of the obstacles is that the community cannot understand the spatial or spatial context of the mangrove ecosystem area. Therefore, we tried to carry out community service activities on Participatory Mapping of the mangrove ecosystem based on the local community in Martajasah Village, Bangkalan. The results of this activity are several zones or areas of the mangrove ecosystem determined by the community itself. Some of these zones include cultivation, conservation, and tourism zones. Each zone has its own role and function for the community. It is hoped that the results of this activity can be realized into a book on sustainable mangrove ecosystem management in Martajasah Village, Bangkalan Regency.

Abstract

Desa Pagagan adalah salah satu pusat penangkapan rajungan di Kabupaten Pamekasan. Penangkapan berlebihan dapat membahayakan kelestarian rajungan. sehingga untuk melestarikan rajungan di suatu populasi maka dibutuhkan informasi mengenai kondisi biologi rajungan. Tujuan penelitian ini untuk mengkaji kondisi stok sumberdaya rajungan, berdasarkan analisis hasil morfometrik yang meliputi distribusi lebar dan berat rajungan, pola pertumbuhan, rasio jenis kelamin dan tingkat kematangan gonad rajungan hasil tangkapan nelayan. Penelitian dilakukan bulan April sampai Mei 2022 di lokasi pendaratan (pengepul). Sampel rajungan diambil secara acak. Hasil dari penelitian mengumpulkan sample sebanyak 455 ekor rajungan (jantan 154 ekor dan betina 301 ekor). Kisaran ukuran lebar karapas adalah 80-165 mm dan kisaran berat badan yaitu 63-278 gr. Hasil analisis hubungan lebar karapas dengan berat badan pada rajungan jantan adalah 2,69, sehingga pola pertumbuhannya disebut allometrik negatif karena nilai b<3. Sedangkan pola pertumbuhan pada rajungan betina adalah 2,95. Setelah dilakukan uji t (α:0,05) menunjukkan hasil nilai thitung lebih kecil dari ttabel (tidak berbeda nyata) atau bersifat isometric dimana pertambahan lebar dan berat rajungan seimbang. Hasil penelitian menunjukkan nilai rasio jenis kelamin rajungan jantan dan betina adalah 1:2. Rajungan betina yang tertangkap sebagian besar berada pada TKG 2 (mature) 259 ekor (86%). Hasil pengamatan terhadap telur rajungan di perairan Desa Pagagan Kecamatan Pademawu Kabupaten Pamekasan, ditemukan empat level komposisi warna telur yaitu warna kuning, orange, coklat dan abu kehitaman.

Abstract

Land cover dynamics in a small island can be determined using Geographic Information System (GIS) approach based on multitemporal image analysis. This study aimed to classify major land cover types and to map land cover changes of Bawean Island. Two sets of 10 meter resolution satellite data ALOS AVNIR (2010) and Sentinel-2A (2020) were used in this study. Satellite image analysis was carried out through several stages namely image pre-processing including radiometric and geometric correction, supervised image classification and accuracy test. Image classification results from 2010 to 2020 showed a significant change in land cover on Bawean Island. The forest vegetation land cover declined significantly from 13,470.5 Ha in 2010 to 8,543.4 Ha in 2020. Most of the area have been converted into paddy fields and built-up areas. The accuracy test and validation were determined by comparing the 2020 Sentinel image classification results with field observation conducted in 2021. The analysis showed good results with 82.52% overall accuracy and 79.66 Kappa coefficient. Further investigation found that changes in land cover on Bawean Island occured due to the agriculture and infrastucture development.

Abstract

The Flores Sea is a central region of Indonesia that plays a crucial role in the circulation of water masses. This area serves as a key pathway for the Indonesian Throughflow (ITF), which transports water from the Pacific to the Indian Ocean. The region is also known for its high productivity, particularly in fisheries. This study analyzes two important oceanographic parameters: Sea Surface Temperature (SST) and Chlorophyll-a concentration. The analyses conducted include monthly averages and anomalies and their relationship with interannual phenomena such as the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). To quantify the relationship between oceanographic parameters and these phenomena, correlation and partial correlation analyses were performed. The results indicate that SST and Chlorophyll-a exhibit seasonal fluctuations, particularly in the northern Flores Sea near Sulawesi Island. These fluctuations are suspected to be caused by seasonal upwelling in the region, driven by the movement of the Southeast Monsoon winds during the East Monsoon season (June–August). Upwelling is concentrated in the northern part of the Flores Sea, along the southern coast of Sulawesi Island. The correlation and partial correlation analyses also show that ENSO and IOD significantly impact the variability of oceanographic parameters in the Flores Sea, with IOD exerting a stronger influence than ENSO. Perairan Laut Flores merupakan kawasan yang terletak pada bagian sentral wilayah Indonesia yang memiliki peranan penting dalam sirkulasi massa air di Indonesia. Wilayah ini merupakan lokasi aliran Arus Lintas Indonesia (Arlindo) atau Indonesian Throughflow (ITF) yang mengalir dari Samudera Pasific menuju Hindia. Wilayah ini juga dikenal memiliki produktifitas perikanan yang cukup tinggi khususnya dalam sektor perikanan. Dalam penelitian ini menganalisis bagaimana dua parameter oseanografi yang cukup penting yakni Suhu Permukaan Laut (SPL) dan Konsentrasi Klorofil-a. Analisis yang dilakukan antara lain adalah rata-rata bulanan, anomaly, dan hubungannya dengan fenomena antar tahunan seperti El Nino Southern Oscillation (ENSO) dan Indian Ocean Dipole (IOD). Untuk mengkuantifikasi hubungan antara parameter oseanografi dengan kedua fenomena tersebut maka dilakukan analisis korelasi dan partsial korelasi. Hasilnya adalah parameter SPL dan Klorofil-a memiliki fluktuasi secara musiman, khususnya yang berada pada sisi utara dekat Pulau Sulawesi. Fluktuasi ini diduga diakibatkan oleh adanya fenomena Upwelling yang terjadi secara musiman pada wilayah ini akibat pergerakan dari Angin Muson Tenggara pada musim Timur (Juni-Agustus). Upwelling terfokus pada wilayah bagian sisi utara Laut Flores (pesisir selatan Pulau Sulawesi). Hasil analisis korelasi dan parsial korelasi juga menunjukkan fenomena ENSO dan IOD memberikan pengaruh yang cukup tinggi terhadap variabilitas parameter oseanografi di Laut Flores. Dimana fenomena IOD memberikan dampak yang lebih kuat dibanding dengan fenomena ENSO.

Abstract

Kehadiran bahan terlarut dalam air berupa TSS berdampak pada sifat optik air laut. Fenomena ini dapat terukur dan bisa diamati dengan menggunakan teknik penginderaan jauh. Untuk memperkirakan konsentrasi TSS menggunakan metode penginderaan jauh, harus digunakan berbagai algoritma untuk mengubah nilai reflektansi piksel menjadi konsentrasi TSS. Tujuan dari penelitian adalah untuk mengestimasi dan memetakan konsentrasi TSS menggunakan data citra satelit multitemporal Sentinel-2 dan membandingkan beberapa algoritma TSS berdasarkan analisis citra dengan pengukuran lapang. Citra satelit multi temporal Sentinel-2 dari tahun 2020-2022 digunakan untuk penelitian ini. Hasil TSS dari pengolahan citra dibandingkan dengan pengukuran lapangan dari 25 titik pengambilan sampel. Pengukuran di lapangan menunjukkan bahwa rata-rata konsentrasi TSS di wilayah studi berkisar antara 24 dan 127 mg/l. Algoritma Liu dan Budiman menghasilkan estimasi TSS dengan standar deviasi tertinggi, sedangkan data algoritma LEL menunjukkan deviasi lebih kecil. Dalam penelitian ini, algoritma LEL lebih valid untuk memperkirakan TSS in-situ (RMSE = 10.75, MAPE = 3.97% dan R2 model regresi = 0.85).

Abstract

Perkembangan webgis yang saat ini belum ada pembaruan berdasarkan kondisi lapang yang terkini sehingga perlu adanya pembaruan dalam manajemen data geospasial melalui webgis Penelitian ini bertujuan untuk menganalisis pemanfaatan sistem informasi geografis berbasis WEB dalam meningkatkan akurasi informasi terkait rekam jejak sumur minyak dan gas bumi. Metode yang digunakan dalam penelitian ini adalah survei lapang dalam mendapatkan informasi yang akurat. Survei lapang (ground check) dilaksanakan untuk validasi data geospasial. Hasil penelitian menunjukkan bahwa penggunaan QGIS sebagai pembuatan webgis dapat memberikan hasil yang baik pada saat dioperasikan melalui komputer ataupun telepon seluler. Pembaruan data informasi dilakukan dengan survei lapang, dimana dari hasil tersebut bahwa perusahaan yang melakukan eksplorasi sudah tidak melakukan pengeboran di lokasi tersebut. Perangkat lunak QGIS terbukti mampu memberikan hasil yang baik dengan memanfaatkan alat tambahan QGIS Cloud karena dalam pengolahan datanya dapat dilakukan secara daring dan luring. Kesimpulan yang didapatkan bahwa data pengeboran perlu adanya pembaruan dalam memberikan informasi yang akurat dan relevan.
