Abstract

Parameter oseanografi merupakan tolak ukur yang menjadi penentu kualitas perairan untuk keberlangsungan organisme perairan. Penelitian ini bertujuan untuk menganalisis kualitas perairan dan menganalisis tingkat pencemaran industri tambak udang di perairan Kecamatan Gantarang Kabupaten Bulukumba. Penelitian ini tergolong survei kuantitatif dengan metode purposive sampling melakukan pengukuran parameter oseanografi pada tiga stasiun yaitu pada stasiun I di aliran air sungai, stasiun II di outlet dan stasiun III di dekat budidaya rumput laut. Sampel air dianalisis secara insitu dan eksitu. Hasil penelitian menunjukkan bahwa berdasarkan PP RI No. 22 Tahun 2021, parameter fisika dan kimia yaitu suhu dan pH masih memenuhi kisaran baku mutu, sedangkan parameter oksigen terlarut dan salinitas tidak sesuai baku mutu yang telah ditetapkan. BOD dan ammonia masih di bawah ambang batas baku mutu, sedangkan parameter kekeruhan, TSS, fosfat, dan nitrat sudah berada diatas ambang batas baku mutu. Indeks pencemaran pada stasiun I pada saat pasang 8,23 dan surut 8,12 dengan tingkat pencemaran sedang, stasiun II pada saat pasang 20,82 dan surut 22,25 dengan tingkat pencemaran berat dan stasiun III pada saat pasang 17,89 dan surut 20,71 dengan tingkat pencemaran berat. Tingkat pencemaran perairan yang paling tinggi berada pada stasiun II.

Abstract

Punagaya waters are one of the seaweed cultivation locations in Jeneponto Regency. In 2005, a power plant was built at that location. This development has raised concerns, especially for seaweed farmers in the area. The sustainability of seaweed cultivation and production in Punagaya waters is primarily determined by the water quality and several other related aspects. The purpose of this study was to find information on the physical and chemical conditions of Punagaya waters used for seaweed cultivation after the construction of the power plant (PLTU) and the possibility of contamination of Plumbum (Pb) and Cadmium (Cd). Samples for physical and chemical measurements of seawater were carried out in-situ at the study site, while the chemical analysis of water in the form of nitrate, phosphate, plumbum (Pb) and cadmium (Cd) was carried out in the laboratory. The results showed that the physical and chemical conditions of the Punagaya waters used for seaweed cultivation after the PLTU construction were still within the permissible limits for seaweed cultivation. However, it needs to be aware of the high-temperature value. The value of heavy metals is still in the lower limit for cultivation for seaweed.

Abstract

The plant species mangrove has been knowed to be effective for the bio-desalination process. However, there is currently no scientific evidence supporting the ability of mangrove bio-desalination when implemented through the floating method. This laboratory-scale study aimed to evaluate the bio-desalination of several mangrove species using the floating method. This study consisted of four treatments and three replicates. Treatments included a control group without mangroves (treatment A) and three treatments using mangroves (treatments B, C, and D), Bruguiera sp., Rhizophora sp., and Avicennia sp., which were positioned floating in a tank using a tray. During the eight weeks of rearing, nutrients were provided through 60 mL liquid NPK fertilization. The results showed that there was a decrease in salinity concentration in all mangrove treatments between 22.5-23.9 ppt from the initial salinity of 30 ppt. Different results were observed for the treatment without mangroves, and the salinity concentration tended to increase until the end of the research to 31.6 ppt. The highest Salinity Reduction Efficiency (SRE) was achieved by Avicennia sp.. (25.1%), followed by Rhizophora sp. (22.8%), and the lowest in Bruguiera sp. (20.3%). The results of this study showed that bio-desalination using mangroves had a significant effect on SRE, and each treatment indicated a significant difference (p<0.05). The results of this study provide initial evidence of the potential of the mangrove floating method for bio-desalination of seawater into brackish water.

Abstract

Fisheries activities red snapper in Pinrang waters is considered to be a small scale and caught with that variety of types instrument catch fish (multi gears) one of them is bubu fishing gear. Now, the level of the utilization of red snapper is believed to have been experience symptoms of over fishing due to the high pressure in the area. The study aims to analyze the size structure and length-weight correlation of red snapper (Lutjanus sp). The study was conducted during 5 months of period, starting from March to July 2019 in Pinrang waters, Pinrang District. The sample of the fish obtained by fishermen using ‘Bubu’ fishing gear. The results showed that the total length structure of males and females of the red snapper was ranging from 32 - 57 cm, while the weight structure of males and females of the red snapper had a wide range from 500 to 2500 grams. The total sample of the red snapper is 163 divided into 68 males and 95 females. The growth pattern of red snapper can be categorized in a negative allometric type with a value of b = 2.3328 which means that the length increased faster than the weight gain.

Abstract

Mangrove snails (Telescopium telescopium) is one of the biota that plays a role in the process of litter decomposition and mineralization of organic matter in mangrove plants. The purpose of this study is to determine the abundance, size structure, growth pattern of mangrove snails (Telescopium telescopium) and water quality in the Lantebung Mangrove Ecotourism in Makassar City. The method of collecting mangrove snails by purposive sampling uses a quadrant transect measuring 1x1 m2 with three repetitions at three observation stations. The water quality parameters measured were temperature, salinity, pH, and sediment. The results showed that the abundance of mangrove snails was 45 individuals (Station I), 46 individuals (Station II), and 45 individuals (Station III) respectively. The length of the mangrove snail (Telescopium telescopium) of station I ranged from 55.5-78.1 mm, station II 52.9-72.6 mm and station III 55.3-77.1 mm.  The weight structure of the mangrove snail (Telescopium telescopium) of station I ranged from 17.0-37.4 g, station II 17.0-30.3 and station III 17.0-41.0 g. The growth pattern of mangrove snails based on the weight length relationship at the three stations showed a negative allometric equation (b<3), i.e. the length increase was faster than the weight increase. The highest abundance of mangrove snails is found at station II and the lowest abundance is at stations I and III. The size of the mangrove snail in terms of shell length at station I is longer than that of stations II and III and in terms of weight at station III is heavier than stations I and station II. The quality of the waters refers to Government Regulation no. 22 of 2021 attachment VIII for marine life that still supports the life of mangrove snails.
