Abstract

Kabupaten Bengkulu Utara merupakan satu dari 7 kabupaten/kota  di Provinsi Bengkulu yang terletak di Pantai Barat Pulau Sumatera. Wilayah pesisir Kabupaten Bengkulu Utara berada pada garis pantai sepanjang ± 115,9 km. Perubahan iklim yang mendorong naiknya permukaan air laut, bencana alam dan aktivitas manusia memberi dampak kerusakan terhadap kondisi wilayah pesisir yang semakin cepat dan kritis. Tujuan penelitian adalah untuk mengidentifikasi kerusakan wilayah pesisir berdasarkan analisis kerentanan di Kabupaten Bengkulu Utara, Provinsi Bengkulu. Penelitian ini dilakukan dengan metode survei. Kegiatan penelitian yang meliputi observasi lapang,  wawancara, pengolahan dan analisis data, serta  verifikasi hasil penelitian, dilakukan selama 15 hari. Analisis data dilakukan secara deskriptif. Kerusakan wilayah pesisir yang diukur dari indeks kerentanan, dihitung menggunakan Rumus IKP (Indeks Kerentanan Pantai). Sepanjang wilayah pesisir Kabupaten Bengkulu Utara, terdapat 22 lokasi yang sudah menunjukkan gejala kerusakan dan dan sudah mengalami kerusakan. Serangai merupakan lokasi dengan IKP tertinggi (wilayah merah), yaitu 67,1 dan 75,0. Ada 8 lokasi yang IKP rendah, 11 lokasi IKP sedang, dan  3 lokasi IKP tinggi. Secara umum, kondisi wilayah pesisir Kabupaten Bengkulu Utara sudah mengalami kerusakan. Penyebab kerusakan adalah degradasi hutan pantai, abrasi dan longsor, pertambangan-Galian C, alih fungsi hutan pantai, pemukiman, kerusakan muara sungai, pendulang emas tradisional, galian tanah untuk industri batu bata, pertambakan, sedimentasi/akresi, intrusi air laut, dan alur pelabuhan.North Bengkulu Regency is one of 7 regencies / cities in Bengkulu Province which is located on the West Coast of Sumatra Island. The coastal area of North Bengkulu Regency is located on the coastline along ± 115.9 km. Climate change, which has led to rising sea levels, natural disasters and human activities, has had an increasingly rapid and critical impact on coastal conditions.

Abstract

Turtles are marine reptiles that are protected because of their endangered population. The Convention on International Trade in Endangered of Wild Flora and Fauna (CITES) stipulates seven species of sea turtles in the world into Appendix I as endangered, protected and not exploited in any form. The number of hatchlings that managed to reach the sea is currently difficult to know, one method that can be used to detect the presence of hatchlings in nature is by using the acoustic method. This study aims to analyze the backscatter characteristics of the turtle hatchlings and to determine the relationship between backscattering and body length of the turtle hatchlings. The benefits of this research are expected to be able to provide information about the value of backscatter and the relationship to the body length of hatchlings that can be used as a basis for estimating the stock or abundance of hatchlings in nature. This research was conducted in the waters of the Tapak Padri pond, Bengkulu City. The research implementation takes about 3 months, from August to October 2020. Acoustic data processing is carried out at the Marine Acoustic and Resource Exploration Laboratory, Marine Department, FMIPA, Sriwijaya University, Palembang. The results obtained are that the average value of TS ranges from -52.74 to -48.45 dB for hatchlings length of 7-9.3 cm. Based on the regression equation, the coefficient of determination (R2) obtained is 0.57, so it is known that the total length affects the target strength value by 57% and 43% is influenced by other factors. it can be concluded that there is a relationship between the total length of the hatchlings with the TS value of the hatchlings or the total length has an influence on the magnitude of the TS value in the hatchlings.

Abstract

ABSTRACT Turtles are reptiles that live in the sea and are able to migrate over long distances along the Indian Ocean, Pacific Ocean and Southeast Asia. Currently the number of turtle populations in nature has greatly decreased. This population decline is caused by natural factors and human activities that endanger the population directly or indirectly. At this time the tagging set technique (ID tag code) is a method that is often used to detect the presence of turtles by attaching tags to female turtles who are landing to lay eggs on the beach or while in captivity or the discovery of the mother turtle by fishermen. One other method that can be used to detect the presence of turtles is to use the acoustic method. The purpose of this study was to analyze the characteristics of the acoustic backscattering energy of the green turtle (Chelonia mydes) and to analyze the relationship between target strength and total body length of the green turtle (Chelonia mydas). This research was conducted in the Tapak Paderi waters pond, Bengkulu City, in August-October 2020. The average target strength (TS) value for green turtles was -48.07 dB. Based on the regression equation, the value of determination (R2) obtained is 0.78. Where this value shows that the total length of the green turtle has an effect of 78% on the average target strength (TS) value, while for 22% it is caused by other factors such as body shape, environmental factors and other factors. Based on the ANOVA test, it can be concluded that there is a relationship between the total length and the value of the target strength (TS) on the green turtle or the value of the total length has an influence on the value of the target strength (TS) on the green turtle.

Abstract

The waters of Pulau Baai are unique waters that are closed or protected which have small pelagic fish resources, used as pelagic fishing areas for local fishermen so that they can help the community's economy. One method that can be used to describe the distribution of pelagic fish density is the use of hydroacoustic technology. This study aims to analyze the value of acoustic backscattering (volume backscattering strength, SV) of pelagic fish and associated with the estimation of the density of pelagic fish in the waters of Pulau Baai, Bengkulu City, through in-situ acoustic measurements. The results showed that in the waters of Pulau Baai the highest average SV value was -50.47 dB, which was thought to have a fish density of 2.57 ind/m3 while for a low average SV with a value of -57.48 dB, it was assumed to have a density of 0.04 ind/m3. The density of pelagic fish is acoustically estimated at 26.47 ind/m3 in the water column of Pulau Baai. The SV value affects the estimated fish density by 69% and is categorized as having a high correlation and a positive correlation direction.

Abstract

Coral reefs are one of the important ecosystems that need data inventory in order to manage marine resources both spatially and temporally. Remote sensing with drone technology is one of the vehicles for collecting data related to coral reef ecosystems in real time. Along with the times, drones are widely used in research both in terrestrial and in coastal areas. This research was conducted on December 4 – 10, 2018 in the Karang Lebar, Seribu Islands, Jakarta. The purpose of this research was to explored the ability of drones as a vehicle to complement field survey data for coral reef mapping. In addition, conducting a pixel-based analysis for coral reef classification based on WorldView-2 satellite imagery using field survey data and additional data from drone data. Based on the results of the study, information was obtained that drone imagery can help visual interpretation in detecting coral reefs. Thus, field survey data that are not covered in the research area can be assisted by the use of drones as a complementary vehicle for field survey data. The coral reef classification process using WorldView-2 imagery can be mapped well. Drone imagery has proven to be an alternative in field data collection as a training area in identifying coral reef objects, such as with massive coral lifeforms that can be clearly seen from drone images. It's just that visual interpretation is limited because of the water column, making it difficult to identify objects.
