Abstract

Tingginya kasus kecelakaan laut di Indonesia saat ini harus menjadi perhatian seluruh pihak, bukan hanya pemilikkapal tetapi juga pemerintah, instansi terkait dan masyarakat yang harus lebih aktif dalam memberikan informasi.Pelabuhan Paotere adalah pelabuhan rakyat yang terletak di bagian Utara Kota Makassar dalam pengelolaannyaberada di bawah pengawasan PT. Pelindo IV. Pelabuhan ini sebagai salah satu pintu gerbang pembangunan kotaMakassar. Kecelakaan yang terjadi di Pelabuhan Paotere baru-baru ini adalah tenggelamnya kapal nelayan KM Aristayang rencananya akan berlayar ke Pulau Barrang Lompo pada Rabu, 13 Juni 2018. Kapal tersebut tenggelam akibatcuaca buruk dan kelebihan muatan. Sistem pemuatan yang tidak mempertimbangkan aspek-aspek keselamatantersebut akan berdampak pada stabilitas kapal yang menyebabkan kapal oleng hingga terbalik. Sangat disayangkanbahwa banyak korban jiwa hanya karena kurangnya perhatian dan pemahaman awak kapal terhadap hal krusial sepertiini. Cara yang baik untuk menghindari korban akibat insiden stabilitas adalah memahami konsep stabilitias itu sendiriterutama bagi pelayaran rakyat. Secara statistik persentase jumlah korban yang terjadi pada pelayaran rakyat terusmeningkat terlebih lagi bahwa konstruksi dan system pemuatan yang diterapkan sering tidak mempertimbangkanaspek-aspek keselamatan antara lain karena stabilitas yang cenderung kurang mendukung. Oleh karena itu,diperlukannya sosialisasi mengenai regulasi muatan kapal hingga pengetahuan tentang stabilitas kapal yangdiharapkan mampu menambah wawasan dan keterampilan awak kapal tentang keselamatan kerja dan diharapkandapat memperkecil resiko kecelakaan dini maupun kecelakaan yang telah terjadi terutama pada Pelabuhan RakyatPaotere Makassar.

Abstract

Breakwaters are highly effective breakwater constructions that can be used to protect harbor waters by interrupting wave energy coming from the deep sea. Widely used breakwaters today are of the pile type, both natural and artificial. The drawback of rock breakwaters is that they are large in size and therefore very expensive to issue. Therefore, a new type of breakwater is needed that is smaller in size and cheaper to build. One solution that can be applied is a suspended breakwater. The purpose of this study is to determine the effect of wave parameters on the coefficient of wave transmission through a suspended breakwater. The research was conducted at the Marine Technology Research Laboratory, Hasanuddin University. The parameters in this study were carried out with 5 variations of wave height, 5 variations of wave period (T), and 3 variations of model length (L). From the results of the research we have done, it can be concluded that the value of the transmission coefficient (Kt) is inversely proportional to the steepness of the wave (Hi/L). Figure 3 shows that when compared between model variations (L1 = 40 cm; L2 = 50 cm; and L3 = 60 cm) with depth conditions (d = 70 cm) and with period variations (T 1; T 1.2; T 1.5; T 1.8 and T2 s), it can be seen that the Kt value is lower in the third model variation, L3 = 60 cm with a value of 0.095 < Kt < 0.53.

Abstract

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.

Abstract

One of the rivers with potential for development into a river transportation system in the city of Makassar is the Tallo River, which is approximately 22.2 km long. This river can connect the Tamalanrea sub-district with the coastal area of Makassar. Currently, the Tallo River is utilized as a transportation route to Lakkang Island, which is one of the tourist destinations. Based on the relatively wide characteristics of the river, the Tallo River can accommodate vessels with a relatively large draft. However, a study is needed to determine the maximum draft of vessels that can operate in the river based on water depth and air clearance at the Reformasi Toll Bridge. The objective of this research is to determine the maximum draft and freeboard of vessels that can operate in the Tallo River, identify areas of shoaling, and calculate the volume of dredging required. The research begins with literature review, collection of secondary and primary data, data analysis, and identification of shoaling points for calculating dredging volume. The data collected includes bathymetric data, tidal data, current data, bottom sediment data, and river discharge data. Based on the data analysis results, the maximum vessel draft before dredging is 1.0 m LWL with an air clearance of 1.9 m from the high tide water level. After dredging, the draft of vessels that can use the Tallo River is 1.5 m LWL. The locations requiring dredging are 13 points, with a total dredging volume of 1283.49.

Abstract

Lakkang is one of the neighbourhoods located in Tallo Sub-district, Makassar City and is a residential area and tourist destination purpose. Lakkang can be accessed from varius directions, namely from Kera-kera and Tallo. To get to Lakkang, people currently use catamaran boats. In order to support shipping to Lakkang, a pier was built on the island called the Lakkang pier. Lakkang Pier is made of wood. The existing pier at this time during the high tide season with flood discharge the pier is submerged in water, the distance between the pier floor and the low tide elevation is 1.93 m and the condition of the pier construction is not safe for the process of loading and unloading goods and getting on and off passengers. Therefore, a pier design is needed that can overcome these problems. The purpose of this research is to conduct preliminary planning of floating docks in Lakkang. The research starts from collecting secondary data and primary data. Secondary data includes spatial planning documents, social economy and river discharge. While primary data include tides, bathymetry, shipload, and ship data. Furthermore, analysis of all data collected was carried out to determine the dimensions of the floating dock. The planning results obtained the dimensions of the planned pier have a length of 9.2 m, a width of 5.2 m, a height of 0.708 m, and a ladder of 0.115 m.

Abstract

Tidal energy is a renewable energy source that provides sustainable energy through the utilization of tidal differences, making it a very promising option. This study examines a more effective tidal energy reservoir model by building a 1:100 scale prototype in the laboratory with several predetermined variations, namely an earthen pond (100, 80, and 60 cm), and flow holes (1.5, 1, and 0.5 cm) with initial tidal height differences of 10 cm, 15 cm, and 20 cm. The model uses a 6-hour time period, which corresponds to a semidiurnal tidal model. The results showed that the highest energy output was 281.84 kWh, achieved with a 1.5 cm flow hole, 20 cm tidal height difference for the initial condition, and 80 cm pond width. For a 1 cm flow hole, the outputs were 1774.8 kWh and 1803.78 kWh for 15 cm and 20 cm tidal height difference for the initial condition with a pond width of 100 cm. Meanwhile, the 0.5 cm flow hole produces potential energy outputs of 2623.8 kWh and 2611.4 kWh for different tidal heights of 15 cm and 20 cm for the initial condition with a pond width of 100 cm. Better model performance can be connected to a mini generator to validate the energy generated from the designed prototype model. Doi: 10.28991/CEJ-2024-010-09-016 Full Text: PDF

Abstract

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.

Abstract

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.

Abstract

Palipi Fishing Port is a fish landing port with the condition of the dock building facing directly to the open sea without any protection of the port pond. This causes fishermen to be afraid to anchor their ships at Palipi Harbor, especially during the west season. In addition, the condition of the soil bearing capacity at the seabed due to thick sediment deposits in the harbor water area makes it difficult to apply a pile-type breakwater. Therefore, in order to function optimally, Palipi Fishing Port needs to immediately have a breakwater that is suitable for its geographical conditions as a protection from ocean waves. Floating breakwater is the solution due to its floating structure and efficient in reducing waves. This research will identify the suitability between wave occurrence at Palipi Fishing Port and the effectiveness of using floating breakwater while still considering the ease of development so that it is expected that the port can function optimally for regional economic development.

Abstract

The Wave Catcher Shore Protection Dual-Slope (WCSP-DS) model in this study is a model of a dual function beach building as a beach protector and a catcher of wave energy, which has two walls, namely upright and inclined walls with an angle of 45°. The WCSP-DS building also has a reservoir at its top to accommodate wave runoff (overtopping). This study aims to determine the reflection in front of the model with variations in the freeboard height of the Wave Catcher Shore Protection Dual-Slope (WCPS-DS) building in a zigzag position. The test was carried out using a 1:20 scale 3D physical model at the Coastal and Environmental Engineering Laboratory, Faculty of Engineering, Hasanuddin University, Makassar. Simulation and data acquisition were carried out in a wave basin measuring 15 meters long, 10 meters wide using a regular wave generation system and the wave height data on the wave probe was recorded automatically. The simulation was carried out with 5 variations of freeboard height on 3 variations of waves, namely wave height and period and 3 variations of water depth. The results showed that there was a significant effect of freeboard height, wave steepness and water level position on WCSP-DS vertical wall height or water depth relative to the wave reflection coefficient in front of the model. The value of the reflection coefficient (Kr) in the relationship between freeboard height and water depth (Fb/d) at a depth of 0.4 meters (d/z = 1.143) ranges from 0.42 – 0.74, at a depth of 0.35 meters (d /z = 1) ranged from 0.44 – 0.74 and at a depth of 0.3 meters (d/z = 0.857) ranged from 0.35 – 0.71.
