<![CDATA[Politeknik Pertanian Negeri Pangkajene Kepulauan perlu memiliki dermaga pendidikan. Keberadaan dermaga bisa sebagai tempat tambat kapal latih Politani dan menunjang praktikum dua prodi baru di jurusan penangkapan ikan yaitu prodi teknik kelautan dan prodi pelabuhan dalam hal pelaksanaan praktikum dan survey oceanografi. Posisi dermaga yang baik merupakan salah satu faktor keberhasilan pembangunan dermaga pendidikan. Penelitian ini bertujuan untuk mengetahui posisi dermaga yang baik dan cocok diterapkan dilokasi pantai dibelakang kampus Politani. Pengambilan data dilakukan pada bulan mei sampai bulan juli tahun 2019. Pengambilan data diawali dengan pengambilan data pasang surut dilokasi kegiatan selama 15 hari dengan interval pembacaan 1 jam untuk mengetahui tunggang pasang surutnya. Setelah itu dilakukan survei batimetri seluas 500 x 1000 m2. Pengambilan data sekunder juga dilakukan yakni pengambilan data angin untuk analisis arah dan tinggi gelombang. Hasil analisis survei batimetri menunjukkan bahwa perairan lokasi dermaga pendidikan Politani sangat landai dan panjang kelandaian cukup jauh kedepan arah laut. Kemiringan garis pantai sampai ± 400 meter ke arah laut masih sangat kecil yakni hanya sekitar 0,43%. Area kiri dan kanan jetti atau groin eksisting juga sangat landai dengan kemiringan kurang lebih sama. Pengukuran pada radius 800 meter dari garis pantai baru menunjukkan kedalaman yang cukup besar yakni sekitar 3,00 sampai 4,00 meter. Berdasarkan pertimbangan tunggang pasang surut yakni sekitar 2,03 meter dan draft kapal maksimal 1,5 meter maka dermaga harus jauh menjorok ke laut (model jetty) yakni sampai pada jarak 850 meter dari garis pantai dengan kondisi kedalaman 3,5 meter dari LWS.]]>

<![CDATA[The Tide Survey was conducted to determine the types of tides and tides around the Tongke-tongke Mangrove Forest Tourism Destination. The results of this study are expected to provide an overview of the test results in the field with the results of numerical tests on the data to be processed. The research was conducted from August to October 2020 in the waters of the Tongke-tongke Mangrove Forest Tourism Destination. The method used is quantitative. Tidal data collection for 15 days at the study location. While the current measurement is carried out twice, namely at the highest (spring tide) and lowest (neap tide) tide and the data presentation is displayed with SMS 10.0 software (Surface water modeling system). From the results of the tide study, it was found that the tide type in the Tongke-tongke Mangrove Forest Tourism Destination is mixed tide, tilted double daily (mixed tide prevailing semi diurnal). In 1 day there are 2 times the tide and 2 times the ebb with ¬ different heights with the tide of 1.36 m. Whereas in the analysis of SMS software.10, where at low tide, the dominant current moves from east to west with an average speed of 0.0067 m / sec and at high tide around the study area the flow moves from west to east the average is 0.0035 m / sec. The average velocity of the current before high tide is greater than that of the low tide, and the implementation of the results of the study of flows and tides of the Tongke-tongke Mangrove Forest Tourism Destination illustrates that the condition of this mangrove forest is very dependent on the natural conditions of currents and tides in supporting the growth and density of mangroves]]>

<![CDATA[Vessels used for purse seine fishing gear operations in South Sulawesi are made of teak wood (Tectona grandis), spinach with a length of 13 – 25 m, a width of 3.30 – 5.87 m and a height of 1 – 1.8 m. Based on the classification of durability and strength of wooden ships, types of teak and spinach are classified as durable class I and strong class II. Good wood for ship building is one that has a durable class I – II and a strong class I – II (Wibowo 1981 in Marlin, 2008). This means that vessels operating purse seine fishing gear in South Sulawesi are well used because they have relatively large durability and strength. Purse seine vessels in this area have a tonnage between 10 – 35 GT. GT calculation based on Director General of PERLA No, PY.67/1/16-02. The main engine used consists of two units of Yanmar brand, Mitsubishi and Yun chai with a power of 20, 27 or 30 PK. In addition, it is also equipped with a 15 PK Jian Dong brand roller machine]]>

<![CDATA[The waters of Takalar Regency are a good fishing area for pelagic fish species. Purse seine vessels are the type of fishing vessels that dominate the area. The purpose of the study was to examine the performance of engine work on the speed of purse seine ships in Takalar Regency. Data is grouped based on HP and ship speed then processed with shipping calculation formulas to obtain HP and ship speed. The result of the calculation of the amount of propulsion for purse seine ships in Takalar Regency with the largest CPI is 330 HP and for the lowest CPI is 115 HP. From the IHP value, a speed of 10.56 knots can be produced for the largest CPI and 2.50 knots for the lowest CPI]]>

<![CDATA[The purpose of this research is to identify the condition of highway drainage channels and evaluate the existing highway drainage network system in accommodating runoff discharge, channel dimensions and flow direction in channels that occur inundation in the Pangkajene Islands State Agricultural Polytechnic Campus area which is expected to help solve flooding problems in the area. The research method used is descriptive quantitative, which is a method of calculation and description of the results of field data processing. Secondary data collection includes; rainfall data for the last 10 years, obtained from the Department of Resources; topographic maps, drainage network maps and situation maps, obtained from the Politani Pangkep Campus planning section. Primary data collection is obtained from direct measurements in the field using a Waterpass measuring instrument to measure elevation and channel length. The results of this study found that the drainage capacity < 2-year and 5-year return period Plan Flood Discharge, so planning is needed to increase drainage capacity]]>

<![CDATA[Indonesian waters have potential ornamental coral resources in South Sulawesi waters, especially in Karanrang Island, which still need to be optimally utilized by the fishing community. The main objective of this community service is to increase the understanding and skills of the community in managing coral transplantation in situ and caring for them in an environmentally friendly modular system aquarium based on re-circulation. Adopting the ABCD (Asset-Based Community Development) method, this approach begins with the identification of local assets, including the expertise and skills of the karanrang island community. Subsequently, capacity building is carried out by utilizing these assets, and the community is actively involved in the planning and implementation process. Results included increased community knowledge on technological innovations of modular circulation systems holding aquarium design at the household scale and post-harvesting of coral transplant farming products for holding in aquariums. This process contributed to the development of the local ornamental coral sector, empowered the community, and opened up product marketing opportunities at both local and international levels.]]>

<![CDATA[This research evaluates the performance of coastal safety structures in mitigating wave runoff through laboratory-scale simulations. Pancana Beach in Barru Regency, South Sulawesi, was selected as the research site due to its vulnerability to wave-induced beach damage. To simulate wave conditions, a wave generator was designed using a 12-volt DC motor integrated into an acrylic wave bath. This research analyses the effectiveness of three types of coastal safety structures: reflectors, sea walls and sloping sea walls. Laboratory experiments measured the wave overflow volume for each type of structure under controlled conditions. The results showed that reflector-type structures achieved the highest efficiency in mitigating wave overtopping, with an average minimum overtopping value of 0.006 m³/ms. The findings emphasise the importance of selecting and designing appropriate coastal protection measures to minimise coastal erosion, protect coastal infrastructure and reduce risks to surrounding settlements. This study contributes valuable insights into the role of engineered structures in enhancing coastal resilience, especially for areas vulnerable to high wave energy.]]>
