The development of a shipyard model requires careful planning and must consider other related sectors. This study focuses on oceanography and environmental aspects in developing a shipyard in the Kutaraja Fishing Port. This study aims to identify the suitable shipyard model for Kutaraja Fishing Port based on the oceanography, environmental, and location in the waters around Kutaraja Fishing Port. The model was then visualized using Autocad software. The model was developed based on measurements of oceanography parameters, including current, depth, wave, wind, tide, and sediment. Meanwhile, the environmental parameters used in this study were temperature, salinity, pH, dissolved oxygen (DO), benthos, and plankton. The result shows that the suitable shipyard model to be developed in Kutaraja Fishing Port is the multifunction model. This model is a combination of three types of docking facilities, which are slipway, graving dock, and floating dock.

“…Kondisi tersebut sesuai dengan penelitian P. pardalis di Sungai air hitam yang menunjukkan rasio 1:1 (Pinem et al, 2016). Hal ini memberikan informasi bahwa rasio jantan dan betina di Sungai Ciliwung berada pada kondisi normal (Rochmady et al, 2013). Hasil penghitungan Nisbah kelamin yang dihasilkan memberikan informasi tingkat keberhasilan pemijahan pada suatu populasi yang diharapkan berada dalam keadaan seimbang atau jumlah ikan betina lebih banyak demi mempertahankan kelangsungan hidup ikan (Adisti, 2010).…”

Pterygoplichthys pardalis is a type of fish that is widely used by people around the Ciliwung River as raw material for food production. In addition, P. pardalis has not been cultivated. The process of fish farming requires a number of information and data on fish such as reproductive biology. Therefore, the research aimed is calculating the reproductive aspects of P. pardalis. The result for this research can be applied for fish farmers to start P. pardalis bredding process. The methods used are P. pardalis sampling, measurement of total length and weight, dissection of samples, calculation of gonad weight and liver weight, egg diameter, fecundity, calculation of gonad maturity stages (GMS), gonadosomatic index (GSI), hepatosomatic index (HSI), relationship of fecundity with gonad weight, relationship of egg diameter with gonad weight, relationship of fecundity with total weight, and length-weight relationship. GMS calculation results showed most male fish found in GMS I, while females were most found in GMS IV. The smallest GSI value was found in GMS I and the highest was in GMS IV both in male and female and the fecundity was 737-3820 eggs with egg diameters ranging from 1.571 mm-4.310 mm. Both male and female P. pardalis have negative allometric growth patterns

“…Perbandingan jumlah individu jantan dan individu betina sama dalam kondisi normal (Rochmady et al, 2012). Jika jumlah individu jantan atau betina memiliki jumlah yang berlebihan, maka hal ini menunjukkan bahwa telah terjadi eksploitasi berlebihan pada salah satu jenis kelamin (Rochmady et al, 2013). Selain itu juga, bisa dipengaruhi oleh perubahan kondisi lingkungan (Susiana et al, 2013(Susiana et al, , 2017.…”

The snail Terebralia palustris is a species of snail that lives in the mangrove ecosystem on Pannikiang Island, Barru Regency, South Sulawesi. This snail is known as "Bakoleng" by local residents. This research is critical to know because these snails are consumed by local residents and to find out the location with the highest density. Sampling was conducted once every month from August 2018 to July 2019. The study was conducted for ten months. Due to unfavorable environmental conditions, the research was not conducted in December 2018 and January 2019. Sampling was carried out using a plot size of 1x1 m2 at stations A and B. Data were analyzed and tabulated using Excel. Male snails were 33.47% and females at station A were 66.53%, while at station B the males were 25.91% and females were 74.09%. The ratio of male snails at station A is 31.88% while at station B is 68.12%. The ratio of female snails at station A is 24.54%, while at station B is 75.46%. The number of female snails is always more than the male. The density of male and female snails was higher at station B. This allowed the snail harvest to be can carry out at station B.Abstrak: Siput Terebralia palustris merupakan salah satu spesies siput yang hidup pada ekosistem mangrove di Pulau Pannikiang, Kabupaten Barru, Sulawesi Selatan. Siput ini dikenal dengan nama “Bakoleng” oleh warga setempat. Penelitian ini penting diketahui karena siput ini dikonsumsi oleh warga setempat dan untuk mengetahui titik lokasi dengan kepadatan tertinggi. Sampling dilakukan sekali setiap bulan mulai bulan Agustus 2018 sampai Juli 2019. Penelitian dilakukan selama sepuluh bulan. Penelitian tidak dilakukan pada bulan Desember 2018 dan Januari 2019 karena kondisi lingkungan tidak mendukung. Pengambilan sampel dilakukan dengan menggunakan plot ukuran 1x1 m2 pada stasiun A dan B. Data dianalisis dan ditabulasi dengan menggunakan excel. Siput jantan sebesar 33,47% dan betina di stasiun A sebesar 66,53% sedangkan di stasiun B untuk jantan yaitu 25,91% dan betina yaitu 74,09%. Perbandingan siput jantan di stasiun A yaitu 31,88% sedangkan di stasiun B yaitu 68,12%. Perbandingan siput betina di stasiun A yaitu 24,54% sedangkan di stasiun B yaitu 75,46%. Jumlah siput betina selalu lebih banyak dibandingkan jantan. Kepadatan siput jantan dan betina lebih tinggi pada stasiun B. Hal ini memungkinkan panen siput dilakukan di stasiun B.
