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

The tidal lake ecosystem is formed by the flow of the Belmera River and seawater through a tidal process along a course of 12 km from Belawan (Malacca Strait). This lake has a tidal lake that has the characteristics of fresh water to brackish water and Mollusc communities from freshwater species to brackish water species. This study was performed to develop a mollusc conservation strategy based on the spatial and temporal distribution of Mollusca in the tides. The study was conducted from September 2018-August 2019. Mollusc samples were taken every month at high tide and low tide using a Petersen grab tool. Nine Mollusca species, consisting of three bivalves and six gastropods, were identified. Polymedosa expansa is a mollusc species that is considered for conservation. The population size of P. expansa is small, and its distribution is limited to the northern lake. P. expansa was found only in September at high tide and in December at low tide. Competition among Mollusca and habitat availability are obstacles to the survival of P. expansa. The habitat of P. expansa is mangrove, and therefore a conservation approach was carried out through improvement of mangrove quality.

Abstract

This research was conducted at two different lakes in Jambi Province (Lake Sipin and Lake Teluk) to compare abundance of aquatic insect larvae (family: Chironomidae). Lake Sipin located close by the settlement and got many influences from anthropogenic activities. However, Lake Teluk got less anthropogenic disturbance. Both lakes have difference plants cover. The area around Lake Sipin was more open compared to Lake Teluk and it caused low transparency level in Lake Sipin. The transparency level of Lake Sipin was 58.62 cm whereas transparency level of Lake Teluk was 70.29 cm. The difference of this transparency level influenced Chironomidae Larvae abundance that was encountered. Larvae abundance which was found in Lake Sipin was 49 ind/m2, while larvae abundance of Lake Teluk was 374 ind/m2. The result showed that water transparency level, water colors and vegetation affected abundance of Chironomidae larvae.

Abstract

The residue of human activities and batik industrial waste water surrounding the river will be able to increase the accumulation of chromium and to disrupt macrozoobenthic communities in the river. The aims of this study was to assess the impact of human activities surrounding the river to the macrozoobenthic communities and the accumulation of chromium in Cimanuk Lama River, Indramayu District, West Java. The study has been conducted from AprilMay 2015 based on three times sampling at three different sampling stations. The result of this study shows that the chromium accumulated in the waters of all station still meet the standard quality ranging from 0,010-0,016 mg/l, but only station 1 fulfills the standard quality for chromium accumulated in the river sediment with the range of all stations was about 11,72-46,63 mg/kg. The results also show that the community index analysis describes the change of macrozoobenthic community at all stations caused by environmental pressure, especially at the station 2 which is indicated by the highest score of Family Biotic Index. The accumulation of the chromium in the waters and the change of macrozoobenthic community structure are mostly influenced by the use of the Cimanuk Lama river long for agricultural and fisheries activities, and also batik home industry.
