ABSTRACT Wastewater from laboratory glassware washing activities contains organic materials. Decomposing bacteria could increase the biomass by utilizing organic matter as a source of carbon. This research was aimed to describe the influence of commercial probiotic application in reducing organic matter content of Proling laboratory wastewater. The research was conducted from February to July 2016 in Aquatic Microbiology Laboratory. The experiment consists of several treatments, those were wastewater (L), wastewater+molase (LM), and wastewater+molase+bacteria from commercial probiotic (LMB). Major parameters observed were COD and bacteria abundance. The results showed that there was significant response difference between molasses and without molasses treatment. Based on COD, the most influenced treatment in decreasing organic matter were LM and LMB. These treatments could decrease COD up to 97% and 91%. Furthermore, the abundance of bacteria in molasses treatment was higher than without molasses. Based on this study, the most effective treatment in reducing organic matter was LMB. Keywords: bacteria, laboratory wastewater, molasses, organic matter

Penelitian keanekaragaman fitoplankton dan beberapa parameter fisika dan kimia perairan perlu dilakukan untuk mengetahui kondisi suatu perairan. Penelitian keanekaragaman fitoplankton di perairan estuari Sei Terusan dilakukan pada bulan Desember 2016. Fitoplankton yang ditemukan di perairan Sei Terusan terdiri dari 3 kelas yaitu kelas Dinophyceae, Coscinodiscophyceae, dan Bacillariophyceae. Kelas Dinophyceae terdiri dari Ceratium sp., Protoperidinium sp.,dan Prorocentrum gracile. Kelas Coscinodiscophyceae terdiri dari Coscinodiscus sp., Skeletonema sp., dan Rhizosolenia sp. Kelas Bacillariophyceae terdiri dari Chaetoceros sp., Pleurosigma sp., Cylindrotheca closterium, dan Pseudo-nitzschia sp. Kelimpahan terbesar dari 4 stasiun pengamatan ditemukan pada kelas Dinophyceae yang mendominansi di semua stasiun pengamatan. Indeks keanekaragaman dari 4 stasiun pengamatan adalah 0,052 â 1,872, indeks keanekaragaman ini < 2,306 sehingga termasuk kategori keanekaragaman rendah dan kestabilan komunitas rendah. Indeks keseragaman fitoplankton di 3 stasiun dari 4 stasiun pengamatan cukup rendah berkisar 0,032 â 0,050 dengan indeks dominansi 0,975 â 0,986. Dengan rendahnya indeks keseragaman menyebabkan adanya dominansi spesies tertentu dan menunjukkan adanya tekanan ekologis perairan. Ceratium sp. dari kelas Dinophyceae mendominansi di semua stasiun pengamatan.Phytoplankton diversity research and some physical and chemical parameters of waters needs to be done to determine the condition of a body of water. Phytoplankton diversity research in waters of the Sei Terusan estuarine was conducted in December 2016. Phytoplankton were found in the waters of the Sei Terusan consists of three classes, namely Dinophyceae, Coscinodiscophyceae, and Bacillariophyceae. Dinophyceae class were consisted of Ceratium sp., Protoperidinium sp., and Prorocentrum gracile. Coscinodiscophyceae class consists of Coscinodiscus sp., Skeletonema sp., and Rhizosolenia sp. Bacillariophyceae class consists of Chaetoceros sp., Pleurosigma sp., Cylindrotheca Closterium, and Pseudo-Nitzschia sp. The higest phytoplankton abundance were found in Dinophyceae that dominated at all observation stations. Shannon Diversity indice of four observation stations was 0.052-1.872, this diversity indice < 2.306 thus categorized low diversity and community stability was low. Eveness indice of phytoplankton in three stations of four observation stations was low enough ranged from 0.032-0.050 with dominance index from 0.975- 0.986. The low Eveness indice due to dominance of certain species and indicate their ecological pressure waters. Ceratium sp. (Dinophyceae) was dominate at all observation stations.Â

Bauxite is one of the mining activities, which can lead to the phenomenon of Acid Mine Drainage (AMD). Activities developed by bauxite mining, since the beginning of operations are able to degrade environmental conditions and cause modifications to the main structure of the environment. Alternative to reducing the negative impact of bauxite mining production with re-utilize abandoned bauxite which forms puddles. The puddle of water on bauxite post-mining have potential for Aquaculture. Each sampling site is located in 5 (five) site based on post bauxite mining activities and determine the heavy metal concentraion of Pb and Cr. Soil and sediment samples were collected to analyze the grain size.  Total heavy metal concentrations using Atom Flame Absorption Spectrophotometer (AAS). Analysis of heavy metal concentration (Pb dan Cr) with enrichment factor (EF) value of heavy metals Pb indicates extremely high enrichment for post-mining bauxite site at Simpang Dompak, Dompak and Wacopek (EF> 40). Enrichment Factor (EF) Cr on post-mining bauxite post in Simpang Dompak and Sei.Carang site have EF value > 5 indicating this site contamination with Cr. Index Value, Igeo > 5 indicating very strongly contaminated Pb and Cr with Igeo <5 is contaminated moderately. Water quality in Post-mining bauxite shows good condition of water. In general, the post-mining area of ââbauskit have potential for aquaculture activities although there is high Pb contamination on the substrate but the water quality parameter can utilized for dynamic organisms such as fish. Proper aquaculture techniques to manage the post-mining bauxite in order to be optimally utilized for cultivation activities.

Primary Productivity on Abandoned Bauxite Mining Pits of Tanjungpinang City, Riau Islands. The abandoned bauxite mining pits in Bintan Island have a good opportunity to be developed, especially as an aquaculture area. The objective of this study was to determine the primary productivity of the waters, phytoplankton ecological index, and physical and chemical parameters of the bauxite post-mining ponds in Tanjungpinang City, Riau Islands. The study was conducted in April-August 2018 in two bauxite post-mining ponds (station 1 and 2) in Senggarang, Tanjungpinang City. The parameters observed were the abundance and ecological index of phytoplankton, aquatic primary productivity, physical and chemical parameters of the waters, and nutrients, N and P. From the study it was found that there were three phytoplankton divisions, consisted of three classes and eight genera. Mougeotia sp. was the dominant species of phytoplankton. The abandoned bauxite mining pits were classified as labile and the phytoplankton communities were under environmental stress due to the dominance of certain species. The abandoned bauxite mining pits were classified as young (inundation <5 years), low primary productivity, as well as oligotrophic waters. Net primary productivity in station 2 was higher than station 1, i.e. 1,23 mgC L-1 day-1 and 0,25 mgC L-1 day-1, respectively. The physical and chemical parameters of the bauxite post-mining ponds studied met the quality standards for freshwater aquaculture activities, except for pH and ammonia.
