Sebagai salah satu destinasi wisata bahari, pantai Gumumae menjadi lokasi liburan potensial bagi masyarakat Kota Bula dan sekitarnya. Memiliki luas 19.70 ha membantang dari Teluk Sesar sampai Sungai Wailola, turut berkontribusi pada pembentukan struktur dan karakteristik pantai. Dinamika fisik pesisir yang kompleks menjadi tujuan penelitian dilakukan. Harapannya pengelolaan Pantai Gumumae sebagai kawasan wisata bahari dapat dilakukan secara tepat dan berkelanjutan. Penelitian dilakukan pada bulan September sampai Oktober 2019, di Pantai Gumumae Kabupaten Seram Bagian Timur Provinsi Maluku. Pengamatan parameter fisik pesisir dilakukan secara insitu dan komparasi data penginderaan jauh, melalui satelit altimetri NASATOPEX/Poseidon, Jason-1/Envisat, dan Jason-2/Envisat tanggal 2 - 17 September 2019. Menggunakan analisis deskriptif kuantitatif, spasial dan temporal melalui citra satelit Landsat 8 dan arcgis imagery 2019, untuk mengetahui pengaruh dinamika fisik dalam bentuk peta tematik. Pantai Gumumae merupakan dataran rendah tetapi dikelilingi wilayah perbukitan disekitarnya. Pola curah hujan berfluktuasi dalam setahun, namun terdapat trend peningkatan sejak bulan September sampai November dan berdampak pada aliran sungai, tidak mengherankan transport sedimen yang dialirkan ke pesisir pantai Gumumae melalui muara sungai Wailola berada dalam jumlah yang besar. Termasuk kategori perairan dangkal dengan kedalaman 45 cm sampai 2.5 meter pada jarak >15 meter dari garis pantai ke arah laut. Tinggi gelombang relatif kecil yakni sebesar 0.68 meter – 0.82 meter, namun memiliki arus yang cenderung cepat di muara sungai Wailola. Anomali permukaan laut di pesisir Gumumae mengalami penurunan secara konstan sebesar 3mm sampai 116 mm. Kecepatan arus dan sudut elevasi perairan pantai mengalami fluktuasi sehingga memberi pengaruh pada arah dan kekuatan arus pantai, gelombang kecil, sedimentasi tinggi di muara hingga sebagian kawasan wisata. Perlu perencanaan yang komprehensif untuk pengelolaan wisata pantai Gumumae berdasarkan kesesuaian tata ruang.

It has an area of 19.70 ha stretching from the Sesar bay to the Wailola river, contributing to the formation of the structure and characteristics of the coastal. The complex physical dynamics of the coastal is the aim of the study. It is hoped that the management of Gumumae beach as a marine tourism area can be carried out appropriately and sustainably. The study was conducted from September to October 2019, on the coastal of Gumumae, East Seram Regency, Maluku Province. Observation of coastal physical parameters was carried out insitu and compared remote sensing data, via satellite altimetry NASATOPEX / Poseidon, Jason-1 / Envisat, and Jason-2 / Envisat on 2-17 September 2019. Using quantitative descriptive analysis, spatial and temporal through satellite imagery. Landsat 8 and Arcgis Imagery 2019, to determine the effect of the physical dynamics of the Gumumae coastline in the form of thematic maps. Gumumae Beach is a low-lying area but is surrounded by hilly areas around it. Rainfall patterns fluctuate within a year, but there is a trand increase from September to November and have an impact on river flow, it is not surprising that sediment transport flowed to the coastal of Gumumae via the Wailola river mouth is in large numbers. Current velocity and elevation angle of coastal waters fluctuate so that it influences the direction and strength of coastal currents. Included in the category of shallow water with a depth of 45 cm to 2.5 meters at a distance of> 15 meters from the coastline towards the sea. The wave height is relatively small at 0.68 meters - 0.82 meters, but has a current that tends to be fast at the mouth of the Wailola river. Sea level anomalies on the coastal of Gumumae are constantly decreasing by 3mm to 116 mm. Need a comprehensive planning for the management of Gumumae beach tourism based on spatial suitability.

Dari hasil penelitian diketahui bahwa kelas interval minimum dan maksimum ukuran panjang dan berat ikan, koefisian korelasi, koefisien determinasi, nilai slope dan status pertumbuhan dari hubungan panjang dan beratikan secara berturut-turut yaitu, November 2019 (15,00 – 18,99 cm, 40,00 – 84,64 gram, r = 0,53, R = 0,28, b = 1,3378, allometrik negatif),Desember 2019 (16,00 – 21,99 cm, 40,00 – 118,87 gram, r = 0,94, R = 0,88, b = 3,1975, allometrik positif),Januari 2020 (16,00 – 19,00 cm, 51,41–96,05 gram, r = 0,81, R = 0,66, b = 2,259, allometrik negatif). Sumberdaya ikan kembung perempuan pada November 2020 diduga telah mengalami tekanan eksploitasi dan terindikasi overfishing. Pada Desember 2019 diduga tidak mengalami tekanan ekslpoitasi dan tidak terindikasi terjadi overfishing. Pada Januari 2020 diduga mulai kembali mengalami tekanan eksploitasi dan terindikasi mulai mengarah kepada overfishing. Pemanfaatan sumberdaya ikan kembung perempuan memerlukan perhatian khusus dalam pengelolaannya oleh segenap stakeholder terkait agar keberadaan ikan kembung perempuan tetap lestari.Short mackerel (Rastrelliger brachysoma) is an important economic value fish in Central Tapanuli Regency, so it is one of the most catch targets by fishermen. This research aims to find indications of exploitation and overfishing pressure of utilization on short mackerel resources. The method of research is observation method. The data are analyzed by descriptive statistics, correlation and regression. the results of show that the minimum and maximum interval classes of length and weight of fishes, correlation coefficient, coefficient of determination, slope value and growth status are, respectively November 2019 (15.00-18.99 cm, 40.00-84.64 grams, r = 0.53, R = 0.28, b = 1.3378, negative allometric), December 2019 (16.00-21.99 cm, 40.00-118.87 grams, r = 0.94, R = 0.88, b = 3.1975, positive allometric), January 2020 (16.00-19.00 cm, 51.4-96.05 grams, r = 0.81 , R = 0.66, b = 2.259, negative allometric). Short mackerel resources in November 2020 are thought to have run into exploitation pressure and indicated overfishing. In December 2019 is suspected that they didn’t run into exploitation pressure and overfishing. In January 2020 is suspected that the exploitation pressure has begun to return and indicated lead to overfishing. Utilization of short mackerel resources requires particular attention in the management by every relevant stakeholder so the existence of short mackerel remains sustainable.
