Abstract

The aims of study are: 1) to assess the accuracy of phytoplankton counts using Lund cell method and parallel samples, 2) to determine the variation of data (cell abundance, species richness and species composition) between time of preservation and within subsamples using 3 and 5 traverses counted and 3) to investigate the effect of storage following preservation with Lugols solution.  The study was conducted from January 2004 to July 2004 at Marine Science Laboratory, Ourimbah Campus, The University of Newcastle, Australia.  The study found that there is a significant variance of data of cell abundance between subsample within number of traverses over periods of preservation.  It showed that number of traverses give a significant effect on cell count between subsamples. The data on species richness differs significantly over periods of preservation.  This finding shows that length of preservation by Lugol’s solution affects the cell.  The species assemblages between periods of preservation are clearly different.  This finding showed that there is an effect of length of preservation on species.

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.
