Abstract

Environmental pollution has become a serious problem in marine environment. Inorganic pollutants was harmful to the environment because difficult to decompose naturally, therefore induce  environmental damage. One anorganic pollutants agent is heavy metal copper (Cu). Algae have a high tolerance to heavy metal copper stress in the environment so it can be used as a bioremediation agent, such as  Chlorella vulgaris Beijerinck. This study aimed to determine the effect of copper to the population growth of Chlorella vulgaris Beijerinck. Research was carried out by inoculated Chlorella vulgaris Beijerinck in seawater culture medium containing copper (Cu) with concentration 0.05 ppm, 0.5 ppm, 5 ppm, and 25 ppm, respectively.  Observation of the growth of Chlorella vulgaris Beijerinck were performed every 24 hours for 14 days by Improved Neubauer Haemocytometer. The results showed that copper with concentration 0.05 ppm and 0.5 ppm increased Chlorella vulgaris Beijerinck  growth populations at day three and  it also inhibit Chlorella growth until day eigth. Chlorella  population then increased sigificantly at day eight until day fourteen of observation.  Copper  with concentration  5 ppm and  25 ppm decreased the population of Chlorella vulgaris Beijerinck and then increased its population at day six. Chlorella population then decreased at ten day of observation.   Key words: growth, heavy metals copper (Cu), Chlorella vulgaris Beijerinck, bioremediation

Abstract

Industrial products such as metal and paint had generate hazardous wastes, one of then is a heavy metal Chromium (Cr). Industrial wastes containing Cr may cause many negative effects when directly discharged to environment without any prior processing. Therefore, recovery actions (remediation) is one of many ways to solve the problem. Phycoremediation is one of remediation that is simple, efficient and safe in process by using the microalgae to remediate the environment, and one of the microalgae is Spirulina platensis (Gomont) Geitler. This study was conducted to determine the effect and the removal efficiency of heavy metals Cr on Spirulina platensis culture media. The results showed there was significant influence between the administration of heavy metal Cr 1 mg/l, 3 mg/l and 5 mg/l Cr on the population growth of S. platensis. Heavy metal Cr concentration of 1 mg/l increased the growth of S. platensis, while the opposite happened when administrated with 3 mg/l and 5 mg/l. Higher concentration of heavy metal Cr on culture media decreased population of S. platensis. The culture added with heavy metal Cr concentration of 1 mg/l, 3 mg/l and 5 mg/l on the 7 days treatment were able to decrease heavy metal Cr level respectively 35%, 14% and 8%. Thus, the longer treatment days the bigger decrease percentage concentration of heavy metal Cr. Keywords: Cr, phycoremediation, microlagae, Spirulina platensis

Abstract

Technical challenges in using diatoms for paleolimnological work are the identification and enumeration of diatom valves. Variations exist in the minimum number of valves to identify, ranging from 100 to 700 valves of the dominant species. This task can be very time consuming, particularly when the diatom valves are not abundant. This research was conducted to determine the minimum number of valves to be identified in the diatom assemblages from Rawapening Lake, Central Java, Indonesia. Based on the 314 samples obtained from Rawapening Lake, the diatom efficiency rose above 0.85 upon the minimum count of 300 valves. The number of diatom species identified remained stable after the minimum of 300 valves. Therefore, the minimum number of diatom’s valves identified to represent the assemblage for paleolimnological analysis was 300.

Abstract

Perubahan lahan memberi dampak pada pengurangan kapasitas resapan khususnya pada riparian sungai yaitu berupa berkurang bahkan hilangnya vegetasi. yang seharusnya menjadi daerah resapan air dan tempat hidup tumbuhan riparian. Dampak ekologi dari berkurangnya vegetasi riparian dapat terjadinya risiko banjir. Jenis vegetasi yang dominan di suatu lokasi dapat dilihat dengan mengetahui nilai tertinggi INP serta keberadaan spesies tumbuhan dilihat dari keanekaragaman suatu vegetasi riparian. Metode yang digunakan metode plot kuadrat. Caranya dengan menmbuat garis transek sepanjang 150m yang dibagi menjadi tiga plot kuadrat, dengan jarak antar plot 40m. Tiap titik tersebut diletakkan plot kuadrat berukuran 10m x 10m untuk pohon, 5m x 5m untuk perdu, dan 1m x 1m untuk herba. Analisis vegetasi, meliputi : kerapatan, dominansi, dan frekuensi. Penelitian dilakukan di kawasan Sub-DAS Sungai Gajah Wong. Hasil dan pembahasan Penelitian ini  berupa ditemukan 49 jenis tumbuhan. Spesies tumbuhan yang ditemukan pada habitus pohon terdiri 13 famili. Habitus perdu terdiri 12 famili, dan habitus terdiri herba 12 famili. INP tertinggi pada habitus  pohon didominasi oleh jenis bambu. INP tertinggi pada habitus perdu didominasi oleh Mimosa pudica yang hampir pada setiap daerah hulu, tengah dan hilir ditemukan, sedangkan INP habitus herba berupa  gulma. Perbedaan indeks keanekaragaman (H’) habitus pohon, perdu dan herba disebabkan oleh berkurang atau bahkan menghilangnya vegetasi akibat perubahan lahan mempengaruhi pola persebaran vegetasi riparian.
