Abstract

Berdasarkan teori, aktivitas fitoplankton dalam proses fotosintesis adalah optimum terjadi di permukaan perairan. Namun,penelitian secara seksama untuk memastikan hal tersebut sampai saat ini belum dikaji secara terperinci untuk perairanpesisir Indonesia. Untuk maksud tersebut, maka telah dilaksanakan penelitian yang bertujuan untuk menganalisis kelimpahanfitoplankton berdasarkan kedalaman di perairan Pulau Barrang Lompo Kota Makassar. Pengamatan kelimpahanfitoplankton dilaksanakan pada berbagai kedalaman yaitu 0, 5, 10, dan 15 m. Analisis sampel menggunakan metodeLackley Drop Microstransek Counting. Hasil penelitian menunjukkan bahwa kelimpahan fitoplankton sangat berbedanyata antar kedalaman. Kelimpahan fitoplankton pada kedalaman 0 m merupakan kedalaman dengan kelimpahan terbaikdan tertinggi.Kata kunci: kelimpahan, fitoplankton, kedalaman perairan

Abstract

Temperature and availability nutrients played an important role on growth and lipid production of microalgae. In this study, we examined the effect of increasing suhu and excessed and depleted NO3 on growth rate, biomass and free fatty acid concentration in the Spirulina sp and Skeletonema sp. Two microalgae were culture on Conway and Milne media for 21 days using continuous culture technique. There were four temperature treatments, such as 28oC, 30oC, 32oC and 34oC and three nutrient treatments, which were control nutrient treatment, without NO3 and two times NO3 concentrations from control treatments with three replicates for each treatments. Results found that increasing temperature significantly affected on biomass and concentration free fatty acid, meanwhile nutrient treatments affected on growth rate, biomass and concentration of organic Carbon. In general, increasing temperature was more affected on Spirulina sp in terms of increasing growth rate, biomass and free fatty acid concentration. However, Skeletonema sp was more responsive to availability of NO3 in the media culture for increasing free fatty acid, and percentage of free fatty acid per dry weight.

Abstract

Culture of ornamental corals applying transplantation technique was aimed to know the successful of this transplantation technique in the ornamental coral culture based on its growth and survival rate of various coral fragments. The location of the medium settlement was in the western side of the waters of Tonyaman Village, Binuang Subdistrict, Polewali Mandar Regency with 3-4 meter depth during low tide. One of coral species i.e. Acropora  sp with 48 fragments was put on 4 transplantation tables. During the experiment, cleaning of fungi and biofouling at the transplant tables and the culture tables. Measurements of the absolute growth and survival rate were done at the 21st day using calliphers and numbers of dead and live fragments were counted directly. Coral transplantation workshop for ornamental coral culture was attended by 4 fisherman groups with total 23 participants. This event was understood by the training participants from the seed selection to the monitoring. Number of coral fragment cultured was 48 fragments obtained from one of stony corals (Scleractania), i.e. Acropora  sp. The range of survival rate that has been cultured for 21 days was adequately high i.e. 91.7 – 100 %. The highest survival rate was observed at the transplant table B, i.e. 100%, whereas, the table A, C, and D were 91.7 %. Average absolute growth of the coral Acropora  sp cultured during this study were ranged from 4.2 – 4.9 mm/month. Aaverage absolute growth was found at table transplant B and C, while the lowest value was observed at the transplant table D.Keywords: cultivation, ornamental coral, transplantation technique, Tonyaman

Abstract

To support the efforts of the Indonesian government in managing marine debris that has a broad potential negative impact in various aspects, beach debris monitoring activities are urgently required in various locations. This research was carried out from June to August 2018 in the west coast region, on Labuange beach, Barru Regency, South Sulawesi Province, Indonesia, which was exposed by the Indonesian Through-Flow. The study aimed to determine the amount, weight and composition of marine debris on Labuange beach. Marine debris was sampled from a permanent line transect with an area of 150 m2 (three replications). Samples were then cleaned, sorted, counted, and weighed. The average amount of marine debris was 5.98 + 2.13 items/m2 per month, with a total weight was 138.69 ± 91.32 g/m2 per month. Plastic and rubber category dominated every sampling period in the location. The abundance of marine debris, both regarding quantity and weight, fluctuated in high amount during the sampling period, which indicated the magnitude of the role of oceanographic factors, including the direction of waves, and lack of community awareness on marine debris impacts and management. The great amount and weight of marine debris and the type of waste, which was dominated by plastic and rubber is a potential threat to humans, marine biota, and the local or global environment.

Abstract

Indonesia has a long costline dan have a high natural fisheries resources. One of natural resources from thecoast area is seaweed. Seaweed is export commudity from fisheries sector and Indonesia is one of the thirdmain producer for seaweed in the world. Seaweed species that have been cultured and utilized was onlyseveral species such as Glacillaria sp, Euchema cottoni and Geledium sp, on the other hand, Indonesia has ahigh diversity of seaweed. Based on LIPI data survey on 1998, it was found that 55 species of seaweed atIndonesian waters. Through this data, it showed that Indonesian water has a high potency for seaweedculture development. Aims of this study were to identify seaweed species that has a high potency to becultured at South Sulawesi’s waters and to analyse natural potency of several seaweed species that can becultured. Results study showed that diversity of seaweed species was varied within South Sulawesi’s waters.The highest number of species account for 30 species that found at Pangkep waters and the lowest number ofspecies was found at Bone waters account for 5 species. There were three class of seaweed that found fromlocations, such as Red, Brown and Green algae. The highest number of species from Red algae class wasfound from Bantaeng waters, furthermore the highest number of species from brown algae class was foundfrom Pangkep waters.Keywords : Seaweed, seaweed culture, South Sulawesi waters.

Abstract

The sea waters of Makassar City have oceanographic characters that are influenced by land. The character then influences the distribution of various organisms that live in it. One example is zooplankton. In this study, an analysis of the density distribution of these organisms was carried out to explain phenomena that might be different and not common in marine waters. In fact, the density distribution was found to be highest in locations near the mainland where the highest density was detected in zones 2 and 1 (zone near land). Zooplankton distribution is directly proportional to the level of turbidity in the sea waters of Makassar City.Keywords : Abundance, Zooplankton, Sea, Macassar.

Abstract

Dalam pasal 1 Butir 23 UU Nomor 01 tahun 2014 perubahan atas UU nomor 27 tahun 2007, reklamasi diartikan sebagai kegiatan yang dilakukan untuk meningkatkan manfaat sumber daya lahan ditinjau dari sudut lingkungan dan sosial ekonomi dengan cara pengurugan, pengeringan lahan atau drainase. Dalam perkembangannya, banyak kasus yang terjadi sebagai akibat dari pelaksanaannya yang tidak mengikuti kaidah-kaidah lingkungan yang tepat. Pada kasus reklamasi pantai misalnya, perubahan kualitas perairan di sekitar lokasi kegiatan dapat saja terjadi sebagai akibat dari pelaksanaan yang tidak sesuai dengan kaidah lingkungan, pada akhirnya memberikan pengaruh terhadap kehidupan organisme seperti fitoplankton. Untuk mencermati hal itu, telah dilakukan suatu penelitian untuk mencermati perubahan kualitas perairan pantai pada wilayah yang direklamsi. Penelitian dilaksanakan pada bulan Maret sampai Mei 2017 di perairan Pantai Seruni Kabupaten Bantaeng di mana pada perairan ini pernah dilakukan kegiatan reklamasi. Berdasarkan hasil penelitian, ternyata bahwa nilai parameter kualitas perairan seperti suhu, salinitas, derajat keasaman (pH), kecerahan perairan, kecepatan arus, Total Suspended Solid (TSS) dan oksigen terlarut (DO) secara umum berada dalam kisaran yang masih bersesuaian dengan kehidupan fitoplankton. Hal ini berarti, untuk kasus kegiatan reklamasi yang dilaksanakan di perairan pantai Seuni Kabupaten Bantaeng tidak banyak merubah kualitas perairan. Kata kunci: Pantai, Reklamasi, Kualitas air, Bantaeng

Abstract

Hard coral Porites lutea is an animal that lives on the ocean floor. This species may live for years and accumulate heavy metals from its surrounding environments. The aims of this study was to know accumulation of heavy metals (Pb, Cd, and Cu) pollution by Porites lutea at different islands in Spermonde Archipelago waters. This study used field surveys around Laelae, Bonebatang and Badi Islands of South Sulawesi. Field parameters measured were oceanographic parameters, metals in water and sediment. Hard coral was extracted using nitric acid, then measured its heavy metal levels using Atomic Absorption Spectrophotometer. Several field parameters such as temperature, salinity, turbidity, pH and dissolved oxygen indicated no differences at each location, whereas the difference was observed in the values of Total Suspended Solid and dissolved oxygen. The results showed the accumulation of heavy metals in the skeleton of Porites lutea was Pb>Cu>Cd and Laelae>Bonebatang>Badi Island.

Abstract

Surface chlorophyll-a (Chl-a) distribution have been analyzed with seasonal variation during southeast monsoon in southern part of Makassar Strait and Flores Sea. Satellite data of Landsat-8 is applied to this study to formulate the distribution of chlorophyll concentration during monsoonal wind period. The distribution of chlorophyll concentration was normally peaked condition in August during southeast monsoon. Satellite data showed that a slowdown in the rise of the distribution of chlorophyll in September with a lower concentration than normal is likely due to a weakening the strength of southeast trade winds during June – July – August 2016. Further analysis shows that the southern part of the Makassar strait is likely occurrence of upwelling characterized by increase in surface chlorophyll concentrations were identified as the potential area of fishing ground.
