Abstract

ABSTRACTEcological aspect (morphometry, a complexity of community structure, trophic state, and carrying capacity) are one of basic information to build comprehensive management concept of aquatic ecosystem, as Lake Cilala.  The concept was addressed to develop ornamental fish floating cage and natural fishery activity.  Lake Cilala is a longwise shape small lake with maximum length, average width, and average depth as 1141 m, 161 m, 2.67 m respectively.  Lake Cilala has various genera of phytoplankton and zooplankton, 8 genera of benthos, 5 genera of aquatic plants, and 12 fish species including planktivore, herbivore, and carnivore fishes.  Those organisms established food chains, by grazing and detritus food chain.  The trophic state of Lake Cilala was categorized as middle to heavy eutrophic level by Trophic State Index (TSI).  The carrying capacity analysis of Lake Cilala is 130 tons/year. It is resulted a possibility to increase ornamental fish floating cage to 165 units from 300 existed units. Furthermore, the carrying capacity for natural fish was reached 3.77 tons/year. Keywords: carrying capacity, food chain, lake fisheries, small lake management, trophic state

Abstract

Spirogyra sp. merupakan salah satu mikroalga yang memiliki potensi sebagai bahan baku berbagai industri. Dalam rangka meningkatkan nilai guna dari potensi tersebut, dapat dilakukan penambahan elemen tertentu, di antaranya kalsium. Penelitian ini bertujuan untuk mengetahui kemampuan Spirogyra sp. dalam menyerap kalsium (Ca) dan nutrien pada lama penyinaran berbeda. Penelitian dilakukan terhadap kultur Spirogyra sp. pada skala laboratorium. Kalsium CaCl2  ditambahkan pada media Gandasil D® dengan perlak an penyinaran diskontinyu dan kontinyu. Setelah satu minggu perlakuan, konsentrasi Ca Spirogyra sp. meningkat sebesar 23,4% dan 21,8%, serta nutrien nitrogen anorganik yang terserap sebesar 67,3% dan 59,5% masing-masing pada perlakuan penyinaran kontinyu dan dikontinyu, namun bobot akhir pada perlakuan penyinaran diskontinyu lebih besar dari kontinyu. Diduga bahwa Ca merupakan elemen yang tidak dibutuhkan dalam jumlah banyak oleh Spirogyra sp. pada proses pertumbuhan alga berfilamen ini.

Abstract

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 – 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 – 0,050 dengan indeks dominansi 0,975 – 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.

Abstract

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.

Abstract

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 ini dilakukan pada bulan Januari 2018. Metode yang digunakan untuk mengambil sampel kerang bulu adalah Random sampling sebanyak 30 titik diperairan Desa Sebong Pereh Bintan. Teknik wawancara yang digunakan adalah Snowball sampling (bola salju), dimana responden yang dibutuhkan untuk peneliti pemula adalah minimal 30 orang. Pemanfaatan ekonomis Kerang bulu (A. antiquata) menggunakan rumus CPUE dan menghitung nilai manfaat langsung Kerang bulu (A. antiquata) di desa Sebong Pereh Bintan. Hasil penelitian menunjukkan rata-rata kelimpahan Kerang bulu (A. antiquata) di desa Sebong Pereh berkisar 5700 ind/ha dan kelimpahan Kerang bulu (A. antiquata) di desa Sebong Pereh Bintan tergolong sedang. Kondisi perairan di desa Sebong Pereh masih memenuhi baku mutu sehingga mendukung kehidupan Kerang bulu (A. antiquata). Total rata-rata hasil tangkapan berkisar 509,75 kg/minggu dengan rata-rata 51 trip/minggu. Pendapatan rata-rata nelayan Kerang bulu (A. antiquata) berkisar Rp. 339.833,-/bulan atau jika diakumulasikan berkisar Rp. 4.078.000,-/tahun. Penelitian lanjutan diperlukan terkait dengan analisis pertumbuhan Kerang bulu dengan data panjang berat, kajian stok kerang bulu (A. antiquata), dan pemanfaatan Kerang bulu (A. antiquata) pada saat musim teduh.
