Abstract

Contaminants entering marine systemts have become environmental issues because of their significantly negative impacts. Coasts of Rumah Tiga Village are connected to Ambon Bay and provide marine habitats and tourist attractions due to their location close to Merah Putih Bridge (including recreations, restaurants and aquaculture sites). These human related activities contribute to the discharge of wastes into marine waters. Due to their location at inshore outer Ambon Bay, marine pollutants from the bay tend to be applied at the location. Because of the concentrated pollutants at the location, the coasts of Rumah Tiga Village are a suitable location to conduct beach clean-ups in Ambon Bay. The beach clean-up activities also aim to allow Study Program of Marine Science of Faculty of Fisheries and Marine Sciences, Pattimura University to raise awareness to its students and local community to care for environment.

Abstract

Maluku is part of the Indonesian territory which is traversed by the meeting point of 3 active tectonic plates, namely the Indo-Australian plate (southern part), the Eurasian plate (Western and North parts) and the Pacific plate (Eastern part). This causes the tectonic activity in Maluku and the islands therein to be quite high, and it is very prone to earthquakes and even tsunamis. Earthquake events cannot be predicted both when and how large the intensity of the earthquake will occur, so it is necessary to carry out early debriefing regarding earthquake disaster mitigation. This activity was carried out at SMP Negeri 8 Ambon Negeri Hutumuri, South Leitimur District, Ambon City, which is one of the coastal schools in Maluku. The material presented included an introduction to Indonesia's tectonic order, definitions of disaster mitigation, actions to be taken before, during and after an earthquake. Based on the results of the socialization, it appears that the students were very enthusiastic and had quite good knowledge regarding how mitigation and evacuation should be carried out.

Abstract

Maluku is one of the archipelagic provinces which is famous for its sea area. The diversity of resources in Maluku needs to be optimally managed. However, there are various pressures on the marine environment due to irresponsible use, it requires human resources who are experts and skilled in managing the potential of these resources. Informal education in the form of counseling and community service will be very beneficial, especially for the younger generation (students). This counseling activity aims to provide students with knowledge about economically important gastropod resources in Maluku. The method used is the delivery of extension materials in order to introduce the marine and coastal environment, the types of gastropods and their benefits. This activity was focused on students in grades 5 and 6. The counseling activity was held on September 15 2022 at SDN 170 Central Maluku - Asilulu school. In general, the students were very interested in this counseling activity. This is evidenced by the interaction of questions and answers with the students. They have been able to understand the importance of maintaining economically important gastropod resources and maintaining their sustainability through practical knowledge about understanding the utilization of available resources.

Abstract

Penelitian ini bertujuan untuk mengetahui resiliensi stok karbon di pesisir Kabupaten Muna Barat dengan pendekatan sosial ekologi. Resiliensi merupakan kemampaun untuk mengembalikan stok karbon mangrove pada waktu tertentu. Penelitian dilakukan melalui observasi dan wawancara kepada para stakeholder. Hasil penelitian menunjukkan bahwa Nilai resiliensi stok karbon dengan pendekatan sosial sebesar 0,75, terdapat enam indikator dengan nilai resieliensi terbaik (R = 1) yaitu tingkat pendidikan masyarakat, tidak adanya potensi konflik, kepatuhan terhadap peraturan, adanya mata pencaharian alternatif, tingkat pemanfaatan mangrove, dan ketergantungan terhadap layanan jasa ekosistem. Nilai resiliensi stok karbon dengan pendekatan ekologi sebesar 0,74. Indikator resiliensi ekologi berupa ketebalan mangrove, rasio produksi semai, dan laju pertumbuhan diameter pada masing stasiun memiliki nilai sebesar R = 0,75. Nilai resiliensi stok karbon dengan pendekatan sistem sosial ekologi sebesar 0,74. Nilai resiliensi tersebut, menunjukkan kemampuan ekosistem mangrove untuk merecovery stok karbon pada tegakan melalui produksi semai dan pertumbuhan diameter. Tekanan antropogenik berupa pembangunan berbagai infrastruktur merupakan tekanan berdampak besar namun tidak berkesinambunagn. Tekanan antropogenik berupa penebangan pohon merupakan tekanan kecil berkesinambungan. Kemampuan reproduksi dan laju pertumbuhan diameter mangrove cenderung mampu beradaptasi dengan penebangan pohon sehingga stok karbon dapat recovery dari waktu ke waktu.

Abstract

This study investigated the characteristics of stratification and vertical stability of southern waters of Tanimbar Islands Regency. CTD Data from World Ocean Database 2018 especially November 1995 to represent second transitional season were utilized in this study. The CTD data were processed using Ocean Data View. This study showed that vertically the temperature of the surface layer ranged between 29 to 30 oC and the thickness of surface mixed layer was found to be 44 m. The thermocline layer has temperature ranging between 12 to 28 oC and a maximum depth of 306 m. Below thermocline layer temperature reduced to reach less than 7 oC (depth > 500 m). On the halocline layer, a high saline water was found between 66 - 94 m depth and was located on the southern part between Barbar Islands and Tanimbar Islands. Water mass was found to be unstable in the mixing layer.

Abstract

Beaches have various shapes as a response from the land to various forces received, such as geological processes, openness to the open sea, frequency of anthropogenic activities both around the coastal area and on the upper land and the configuration and layout of the island. The aim of this community service is to introduce the types of beaches and their dynamics to students at Sekolah Menengah Atas (SMA) Negeri 22 Kairatu and to instill a caring attitude towards caring for and protecting the marine and coastal environment. The mechanism for the stage activities is the delivery of material by the PkM Implementation Team from the Department of Marine Science, Faculty of Fisheries and Marine Sciences, Pattimura University and discussion. The results of the activity show that students understand well the material provided including the definition of beaches, functions and benefits of beaches, types of beaches and their dynamics as well as beach protection measures. This can be seen from the response of students who participated actively and enthusiastically by asking various questions during the activity.

Abstract

The Tanimbar Islands are an area of high tectonic activity and are part of the outer arc island chain formed by subduction in the Banda zone. The presence of the Sorong Fault and Tanimbar Fault around the Tanimbar Islands also affects the level of vulnerability to earthquakes and tsunami hazards. The purpose of this study was to predict the tsunami potential and affected area of the Tanimbar Islands. The method of analyzing the height data and predicting the affected area used COMCOT v1.7 software. Model simulations were performed on the domain layer by using linear equations. Earthquake and fault parameter data were obtained from the USGS website using historical earthquakes dated January 10, 2023. Bathymetry data were obtained from the GEBO website at a resolution of 15-arcsecond (464 m). The model simulation results show that the initial wave height value marked by the red contour is 0.22 m and the lowest low tide value marked by the blue contour is -0.4 m. Based on these results, the tsunami potential in the Tanimbar Islands is not dangerous, as the potentially affected areas in the study area are Selu Island, Woluaru Island, Wotap Island, and Molu Island, as well as the small islands in the western part. The simulation results demonstrate the importance of research related to tsunami hazards that may occur in the future so that appropriate mitigation can be planned for the existence of small islands around the Tanimbar Islands.

Abstract

Many studies on the Mentawai tsunami have been carried out. Still, not many have reviewed the validation of run-up height compared to the results of field studies in the same year as the Mentawai tsunami on October 25, 2010. The survey of the Mentawai tsunami reconstruction using COMCOT v1.7 aims to validate The tsunami run-up height of the model output was compared with the results of the field study by the GITST Team in 2010. Validation of the model was carried out using the Aida parameter, by calculating the ratio of the comparison between the model output and the field study results. The study location of the model is divided into 3 layers, namely layer01 covering Sipora Island, North Pagai Island, and South Pagai Island, layer02 covering North Pagai Island and South Pagai Island, and layer03 with the focus of observation on Sibigau Island, with bathymetric resolution used for each layer. 464 m, 232 m, and 77 m so that the propagation at the observation site can be seen clearly. The height of the modeled tsunami ranged from 2.5 – 11.2 meters, with a maximum run-up height observed on Sibigau Island of 11.2 meters, and the time range for the tsunami arriving on land was 5 – 15 minutes. The comparison ratio between the model results and the field study is K = 0.9 and k (standard deviation) = 0.16. Based on the comparison ratio, the model output is close to the actual result.
