Abstract

Pantai dan pulau-pulau kecil berpenduduk di Indonesia umumnya, dan di Sulawesi Selatan khususnya masih belum dilengkapi oleh tata kelola lingkungan hidup yang baik. Contohnya, sangat umum di jumpai di pantai dan pulau-pulau kecil tidak memiliki tata kelola sampah dan limbah yang baik. Banyak pantai dan pulau-pulau kecil kita kelihatan dan menjadi sangat kotor, jorok, dan tidak sehat. Pantai Losari, Kelurahan Losari, Kecamatan Ujung Pandang, Kota Makassar merupakan salah satu pantai di  Sulawesi Selatan yang mempunyai kepadatan penduduk yang cukup tinggi.  Kelurahan Losari cukup luas and padat serta menghasilkan sampah organic rumah tangga dan sampah daur ulang yang cukup besar.  Sampah organic dan sampah daur ulang ini dapat menjadi potensi yang cukup besar untuk mendapat penghasilan tambahan bagi masyarakatnya.  Penghasilan tambahan ini didapat dari pengolahan limbah organic menjadi kompos dan sampah daur ulang menjadi kerajinan/produk yang bernilai ekonomis (dapat dijual).  Namun, masyarakat belum mengetahui dan memahami teknik pengolahan limbah organic dan limbah daur ulang, sehingga potensi yang cukup besar dari limbah organic dan limbah daur ulang yang dihasilkan oleh masyarakat di Kelurahan Losari belum termanfaatkan untuk meningkatkan pendapatan rumah tangganya.Kegiatan pengabdian pada masyarakat ini bertujuan untuk menerapkan teknologi pengolahan limbah domestik  organik dan sampah daur ulang dan mengadopsi teknologi  kepada masyarakat melalui pembuatan berbagai produk/kerajinan tangan dari sampah daur ulang di Kelurahan Losari, Kota Makassar.Hasil kegiatan pengabdian pada masyarakat Program Studi Manajemen Sumberdaya Perairan, FIKP Unhas, menunjukkan bahwa tingginya tingkat partisipasi masyarakat mengikuti kegiatan ini dan besarnya minat khalayak sasaran untuk membuat berbagai produk kerajinan tangan untuk meningkatkan nilai tambah dari limbah organic domestic melalui proses composting.

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

Phytoplanktons are primary producer, which determine the waters productivity. The assemblages of phytoplankton in the lake varied spatially and temporally as a result of nutrient concentration, some physical and chemical factors. However, the assemblage of phytoplankton in the lake was not well documented.  The overall aim of the study was  to count and identify phytoplankton taxa and to examine assemblages at location with and without ooze, and to relate the presence/absence of ooze to phytoplankton abundance and assemblages. The samples were collected from Myall Lakes, NSW Australia. The data were analysed using multivariate analysis to determine assemblages of phytoplankton amongst location. Furthermore, univariate analysis was used to examine how the water quality was in particular presence/absence of ooze affected to phytoplankton abundance. The hypothesis being tested was: (1) phytoplankton assemblages vary spatially in Myall Lake due to varying water quality characteristics, including presence of ooze, (2) there was a significant difference of phytoplankton abundances between locations due to presence/absence of ooze.In both instance the hypothesis on this study was accepted. There was a significant different not only phytoplankton assemblages but also phytoplankton abundance within locations. It concluded that the phytoplankton varied spatially in those locations. Presence/absence of ooze affects abundance of phytoplankton. However, further study was needed to conduct in particular to determine certain aspects which affect the assemblages and abundances of phytoplankton.

Abstract

Microplastics is a problem that has been concerning, especially in marine habitat. The presence of microplastics in large quantities will have an impact on the environment and marine organisms. Marine organisms that are vulnerable to contamination by microplastics pollutants namely green mussels (Perna viridis). This study aims to determine the microplastics forms and concentration found in green mussels (Perna viridis) in Maccini Baji Waters, Labakkang District, Pangkejene Kepulauan Regency, South Sulawesi. The sampling of the mussels was carried out by the method of purposive random sampling with the sample was grouped into 3 groups of shells lengths, namely 2-3.9 cm, 4-5.9 cm and 6-7.9 cm with 33 individuals for each group. Microplastics observations were carried out using a stereo microscope. In addition to analyze microplastics concentrations, an analysis of the frequency of microplastics presence in shells was also carried out. The results showed that the microplastics was found in the form of fiber and fragments with several colors namely clear white, blue, black, red, and purple. The frequency of microplastics presence in green mussels was above 50% with an average of 71.7% exposure to microplastics. The highest frequency of microplastics presence and concentration in the range of shell lengths accounting for 2-3.9 cm.

Abstract

Microalgae are one of the natural resources that have high potential as a source of biofuels, one of them is the marine microalgae Melosira sp.. The objective of this study was to determine the effect of increasing temperature and nitrate concentration on the abundance, growth rate, biomass, organic C-content and free fatty acids of Melosira sp.. A Completely Randomized Design was used for this experiment with four temperature treatments and three nitrate concentrations treatments  in microalgae test planting media. The test microalgae were cultured for 21 days, while the abundance of Melosira sp..was carried out every 3rd day, while for other parameters measurements were made at the end of the experiment. The results showed that the increasing in temperature and nitrate concentration in culture media significantly affected the abundance of Melosira sp.. Meanwhile, the results of statistical analysis showed that the increase in temperature and concentration of culture media did not have a significant effect on biomass except at 30°C treatment, the dry weight of Melosira sp. was only significantly different between the nitrate concentrations of 0.0 g/L and 0.4 g/L. For the content of C-organic and free fatty acids generally showed a significant difference between treating temperature and nitrate concentration in the culture media.

Abstract

Climate change and global warming cause massive damage to the environment. One of the major events that arethreatening the marine ecosystem is coral bleaching. Coral bleaching occurs when corals are exposed to above or belownormal temperatures. The aims of this study are to compare the resistance of Isopora palifera and Acropora hyacinthusfrom Karanrang Island to temperature stress. Four treatment temperatures (28ºC, 30ºC, 32ºC, and 34ºC) were tested toassess the role of temperature stress and bleaching to Isopora palifera and Acropora hyacinthus for 48-hours. Theabundance of zooxanthellae counted as the temperature stress variable. The results showed that there was a difference ofcoral response tothe treatment based on the time of experiment, after 48-hours experimentexposed at temperaturetreatment of 34°C the abundance of zooxanthellae from Isopora paliferawas 0,06 x105 cm-2 and the abundance ofzooxanthellae from Acropora hyacinthus is 0,18 x105cm-2. In comparison between species, Isoporapalifera taken fromKaranrang Island was more resistant to temperature stress thanAcroporahyacinthus.

Abstract

Plastics become debris in the ocean that can be broken down into tiny particles of micro size (<5 mm) and scattered into columns to the bottom of the water. Its very small size makes it easily accessible to various aquatic organisms, such as plankton, crustacean, and mussel. There have been many studies use mussel as a bioindicator for microplastic pollution but no one has observed the effect of microplastic exposure to mussel mortality. The aim of study was to examine the effect of microplastic on mussel mortality. Green mussels were collected from Mandalle Waters, Pangkep Regency (Pangkajene Kepualauan) then were exposed to microplastic polyethylene originating from shieving of scrub soap. The exposure was carried out for 7 days with microplastic concentrations of 0.05 (A), 0.5 (B), and 5 (C) g/L. Statistical test results showed the treatment B and C were not significantly different, but the two treatment were significantly different from treatment A. The percentage of green mussel mortality during the experiment increased with increasing microplastic concentrations with the percentage of mortality exceeding 80% at treatment C.
