Abstrak. Selang sepertiga abad terakhir, Sulawesi yang dikelilingi lempeng tektonik kecil dan besar, telah terkena 270 kali gempa bumi ber-magnitude di atas 5.0. Jumlah ini ditengarai semakin lama akan semakin bertambah setiap tahunnya, yang bermula pada kenaikan aktifitas Sunda Arc pada tahun 2004 silam Tujuan penelitian ini adalah menentukan area paling potensial untuk kejadian gemba bumi bawah laut dan tsunami di pantai perairan Pulau Sulawesi, dengan menganalisa data historis gempa bumi dan tsunami serta melakukan simulasi kejadian tsunami di berbagai area. Didapatkan bahwa untuk periode 2010-2020 akan terjadi minimal 49 kali gempa bumi dengan magnitude di atas 5.0; yang mana hampir semuanya berpusat di lautan dan berkemampuan untuk membangkitkan tsunami. Area yang memiliki potensial terbesar adalah North Arm (Lengan Utara) Pulau Sulawesi, khususnya pantai Utara, Selatan dan Timur dari North Arm. Abstract. From the middle of 1970âs until now, the Sulawesi Island which is surrounded by several small and big tectonic plates had been struck 270 times by earthquake above 5.0 in magnitude. This number of occurrence tends to get higher and higher each year, beginning after the raising activity of Sunda Arc past last six years, which recently struck Padang, West Sumatera in September 2009. The goal of this study is to find out the most potential areas for seismic and tsunamis activities in Sulawesi Island, by analyzing the historical data of earthquakes and tsunamis at the areas and also base on the simulation of several artificial tsunamis. It found out that the earthquakes with magnitude above 5.0 in the period of 2010-2020 will occur minimally 49 times; with almost all ofÂ them will be sea-epicentered which believe could generate tsunami on some areas. The most potential areas will be the North Arm of Sulawesi, especially in the coasts of North, South and East.

Coastal and marine geohazard threats can occur in coastal tourism areas in Makassar City. Several coastal tourism sites in Makassar City are managed by the community, namely by the Tanjung Merdeka Community Empowerment Agency (LPM) and acts as a partner for socialisation activities. Tourism managers are still ignorant of the potential for coastal and marine geohazards, such as the lack of information on geohazard signs and the potential for accidents that lead to disasters for tourism visitors. Socialisation of coastal and marine geohazards in Makassar City's coastal tourism areas has been carried out with an increase in the average knowledge of participants by 45.3%. The increase in partner knowledge includes awareness, preparedness, and disaster response attitudes about coastal and marine geohazard phenomena in coastal tourism activities, which can ultimately encourage and realise partners as community-based tourism managers who implement early warning of disaster risk and occupational safety. Strengthening partners is realised by handing over coastal and ocean geohazard signs as an early warning of disasters that can occur at tourist sites.

Human life cannot be separated from the use of energy. Energy is needed for many things like cooking, traveling, and working. Currently, electrical energy is the main need. To produce electrical energy, power plants that utilize renewable and non-renewable energy sources are needed. Technology in the field of renewable energy continues to experience rapid development. The use of renewable energy aims to reduce the impact of global climate change and reduce dependence on fossil fuels. A variety of natural resources are available as renewable energy alternatives, one of which is marine power technology. Marine energy technology is a technology that utilizes various properties and movements of the ocean to generate electrical energy. Energy sources from the sea can be utilized by using marine technology such as ocean current technology, ocean wave technology, and ocean thermal energy conversion. This technology makes it easy to adapt to the characteristics of the exploited sea.

Makassar is one of the cities in Indonesia that is unlikely to be free from natural disasters. The problem is that the community, especially school-age children, is not yet responsive and alert and does not understand disaster preparedness's importance. Low knowledge, lack of information provision, and disaster risk management can increase the number of victims. Athirah Islamic School, one of the partners in this service, provides facilities for Psychoeducation activities for students. From this problem, a solution for disaster risk reduction is needed by giving psychoeducation (disaster mental health) and disaster preparedness around general reactions (behavior, emotion, cognition, and physical). Psychoeducation materials will be delivered by the Bosowa University psychology team, also partners in this Service activity. The implementation method of this service program includes mentoring and disaster preparedness training from a psychological perspective. The research method used in this service is experimental with a pretest-posttest design approach. The statistical analysis results showed a difference in student knowledge regarding disaster preparedness before and after participating in psychoeducation with a sig <0.05. This service concludes that the training provided to Athirah Bukit Baruga Islamic Middle School students positively impacts students' disaster preparedness knowledge.

The tourist activities at Blue Beach are divided into 3 categories: swimming, water rides and fishing. The implementation of activities in the water poses a risk to tourists, which has the potential to cause accidents and even fatalities. This is due to the lack of segregation of areas for the implementation of the three beach tourism activities, which makes it difficult for tour managers to monitor tourists. For this reason, tour managers will be equipped with knowledge on the importance of dividing beach tourism activity areas based on bathymetric contours and the use of warning flags as safety signs for beach tourism activities. This socialisation can increase the awareness of tourism managers of potential hazards and disasters in the tourist sites they manage, by completing early warning signs of potential hazards of beach tourism activities. This socialisation is done in partnership with community-based tourism managers, namely Non-Governmental Organizations (NGO) of Tanjung Merdeka. The increase in knowledge and understanding of the socialisation material among the participants was 44.9 points. The service activity safety sign products were submitted by the service team in the form of a Blue Beach tourism activity map based on bathymetry contours and beach safety warning flags as occupational safety and health-based signs in the Blue Beach tourism area.

The existence of coral reefs in Indonesia ranks first in area and type. The total area of coral reefs owned by Indonesia is 14% of the total area of coral reefs in the world. Coral reefs have an important value in life, both in terms of ecology to promising economic value. Therefore, the Department of Marine Engineering in collaboration with partners of the South Sulawesi Provincial Tourism Office held an activity “Coral Transplantation as an Environmental Care Action for sustainable use”. This activity has the aim of providing an understanding of the importance of knowledge about the economic and environmental benefits of coral reefs as a beach / sun tourism attraction for domestic and foreign tourists to visit the province of South Sulawesi, especially on Badi Island in Pangkep Regency (Pangkajene Islands). Coral reefs that have been damaged require a long time to recover, due to the slow growth rate of corals. Therefore, human intervention through various methods and means becomes indispensable to improve and rehabilitate the condition of coral reefs. One rehabilitation technique that has been widely recognized and applied in various parts of the world is coral transplantation. By using lecture and discussion methods, as well as coral reef rehabilitation efforts through the real action of coral transplantation. The results obtained showed that there was an increase in knowledge before and after the community participated in the activity and the degradation of coral reefs that occurred could be restored through transplantation of 500 donor corals. The conclusion of this activity indicates that the presentation of material in the form of lectures and discussions has increased community knowledge, and the real action of coral reef transplantation can increase coral reef colonies as a sustainable use.
