Abstract

Produksi ikan di Muara Gading Mas menurun dengan adanya larangan penggunaan alat penangkapan ikan Pukat Hela (Trawls). Akan tetapi saat ini produksi ikan menunjukkan peningkatan seiring perkembangan alat tangkap modifikasi dari trawl yaitu jaring arad. Namun, informasi mengenai pola distribusi hasil tangkapan mulai dari ikan didaratkan di TPI sampai ke konsumen belum tersedia, selain itu belum pernah dilakukannya prediksi hasil tangkapan guna mendukung pasokan distribusi. Tujuan penelitian adalah mengetahui pola distribusi hasil tangkapan jaring arad dan menguji metode prediksi hasil tangkapan. Metode yang digunakan adalah studi kasus dengan pelaksanaan pada bulan November 2021 hingga Maret 2022. Guna mengetahui pola distribusi analisis yang diterapkan adalah Supply Chain sedangkan metode pengujian menggunakan analisis Conjugate Gradient pada Back Propagation Neural Network dalam memperoleh nilai terbaik. Didapatkan hasil dari analisis supply chain bahwa TPI Muara Gading Mas sudah mampu menyediakan pasokan untuk daerah sekitarnya sebesar 94% namun untuk tujuan luar kota sebesar 6%. Berdasarkan hasil pengujian BPNN, learning rate dengan 0.1, toleransi error 0.01 dan epoch 50 telah memperoleh akurasi terbaik dengan nilai mean square error (MSE) sebesar 1.2446 x 10-6. Hasil penelitian menunjukkan bahwa algoritma BPNN dapat diterapkan untuk metode prediksi alternatif.Kata kunci; Arad, Distribusi, Ikan, TPI Muara Gading Mas, Prediksi

Abstract

Mangrove merupakan ekosistem utama yang mendukung aktivitas kehidupan wilayah pesisir. Manfaat dari hutan mangrove tentunya sebagai penyeimbang siklus biologis di lingkungan pesisir seperti tempat pemijahan (spawning ground), daerah asuhan (nursery ground), daerah mencari makan (feeding ground), dan sarang dari berbagai hewan. Namun, meningkatnya pertumbuhan masyarakat di kawasan pesisir khususnya pada daerah hutan mangrove, karena kebutuhan primer akan tempat tinggal harus terpenuhi maka masyarakat pesisir memanfaatkan areal hutan untuk pembangunan. Salah satu desa yang mengalami peningkatan pertumbuhan adalah Desa Bedono yang terletak di Kabupaten Demak, Provinsi Jawa Tengah. Sehingga terjadinya perubahan luasan mangrove di Desa Bedono. Untuk mengetahui berapa besar penyebab dan dampak adanya perubahan luasan mangrove ini perlu adanya informasi terkait luasan mangrove dan dampak lingkungan di Desa Bedono sebagai pendukung kebijakan pembangunan. Metode yang digunakan menggunakan penginderaan jauh. Melalui peranti lunak (software) yang digunakan untuk proses pengolahan dan interpretasi data adalah: ArcMap versi 10.7.1, Google Earth Engine dan Microsoft Excel 365. satelit Landsat 8 dengan Path 120/Row 65 pada tanggal 19 Agustus 2016 dan Path 120/Row 65 pada tanggal 7 April 2021. Hasilnya didapat luas mangrove di Desa Bedono pada 2016 sebesar 235.58 Ha dan pada 2021 sebesar 168.47 Ha.Kata kunci: Desa Bedono, Mangrove, Penginderaan Jauh, Lingkungan

Abstract

Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami.
