Abstract

Bangka Belitung Islands Province is one of the tin-producing areas, where tin mining activities are always leaving degradation the soil, vegetation and wastes that are toxic, especially some heavy metals such as Pb, Cu and Zn in soil and in the former tin mine excavation called kolong. Greatly affect the quality of waste water and cause pollution, it is feared could extend to land and waters around so that endanger residents. Based on the results of research conducted on the measurement of three former tin mining at different age levels (0, ±8, and> 15 years), it can be concluded that the older age, so the content of heavy metals (Cu, Pb and Zn) is decrease. This is caused by several factors, such as the ability of aquatic plants (Lepiromia micronata) which accumulate heavy metals and other factors such as rain water dilution and precipitation. The results showed that endemic plants can absorb heavy metals. Therefore, heavy metal reduction of tin mining in Bangka Island using phytoremediation method by aquatic plant, because it is relatively inexpensive, easy and environmentally friendly.

Abstract

White leg shrimp is one of 110 Penaeid species which have more profitable chances to cultivate. These shrimp could produce 10 – 20 tons per Ha compare with tiger prawn that only produce 2 – 5 tons per Ha. White leg shrimp could be harvested less than 120 days, and it more resist to the disease, not only that, the other advantages of these shrimp was its habit that live at all over the teritorial of the media so that it can be cultivate with higher density. The optimal result or product from brackishwater pond cultivation is according to how the technical nursery was done. Water quality was the most important point that must be checked and controled to gain the optimal production. The following fertilization was an alternative way to stabilize the water quality especially in traditional pond. This manner could make the bio-organism such as fitoplankton and benthos as white leg shrimp’s natural food grow continously. The study was done with four different doses of the following fertilization (2,5%, 5%, 7,5%, and 10% from forward fertilization). After 86 days rearing period, the best following fertilization shown with the dose 5% from forward fertilization. Water quality such pH, ammonium, sulfic acid and dissolved oxygen with this manner reached the best condition and significantly different from the other (p<0,05 for dissolved oxygen and sulfic acid; and p<0,01 for pH and ammonium). In spite of the water quality, the pond with 5% following fertilization got the best result of harvesting. This manner had the greatest biomass, and average body weight and was high significantly different from the other (p<0,01) The survival rate was got the highest mark although its not significantly different from the test (74,147%) and so as the average daily growth (0,194 gr per day).

Abstract

Nowadays, the chemical ingredients of several additional foods had known as carcinogenic materials. To avoid that, some kind of natural materials are used to be an alternative which it safe and had a lot of important function because of their bioactive essences. Some of them are curcuma ginger and union. This research is done to prove the advantages of using natural additional nutrition from curcuma ginger and union’s essences for African catfish growth performance. The survival and growth performance of African catfish (Clarias gariepinus) fingerlings fed with natural additional nutrition from curcuma ginger and union’s essences raising better than normally nursery. After 45 days rearing period, the percentage fingerling survival for the treatment is 98.33% better than control that only 86.67%. Fingerlings with treatment had the greatest average daily growth, mean body weight, and final average length and was significantly different (p<0.05) from control. Beside of that, the treatment with additional nutrition has undirectly effect to water balance system. This treatment could stabilize the water pH on rearing aquarium.

Abstract

Patin (Pangasius pangasius) and Dumbo catfish (Clarias gariepinus) is being semi intensively cultured on floating net; in the lakes of tin mining activity called Kolong; by farmers in Bacang village, subdistrict of Bukit Intan, Pangkalpinang regency. This spesies is best suited for culture in kolong because of their well adapted of environmental change; even in a size-limited ponds; for growing normally. Kolong should be the decades in one age. Feeding Patin (Pangasius pangasius) and Dumbo catfish (Clarias gariepinus) cultured with this method should more profitable if we substitute the formulated meals (pellets) with chicken guts, as the alternative feed. The main differences would be on their variabel cost, profit value, Break Event Point (BEP), Return of Invesment (ROI) and Benefit Cost Ratio (B/C)

Abstract

Kabupaten Pemalang merupakan salah satu penghasil kepiting bakau di Jawa Tengah. Kepiting bakau merupakan salah satu komoditas perikanan andalan Kabupaten Pemalang yang mempunyai nilai ekonomi tinggi dan dapat dikembangkan secara komersial. Namun demikian, pengelolaan potensi kepiting bakau di Kabupaten Pemalang belum optimal. Dikarenakan belum adanya data yang menunjukkan bagaimana pola pertumbuhan dan persebaran kepiting bakau di kawasan pesisir Desa Mojo. Penelitian ini dilakukan di Desa Mojo,Kecamatan Ulujami, Kabupaten Pemalang. Penelitian ini bertujuan untuk mengetahui pola pertumbuhan kepiting bakau di kawasan Desa Mojo Kecamatan Ulujami, Kab Pemalang. Data yang didapat kemudian dianalisa dengan menggunakan metode regresi untuk mengkaji hubungan antara lebar karapas kepiting bakau dengan berat/bobot tubuhnya. Distribusi frekuensi lebar karapas dan berat kepiting dapat digunakan untuk mengetahui modus dari ukuran lebar karapas dan berat kepiting tertinggi dan terendah pada masing-masing lokasi penelitian yaitu kawasan Muara, Tambak, serta Laguna. Kepiting bakau yang tertangkap pada kawasan Muara,Tambak, serta Laguna juga memiliki interval lebar karapas maksimum dan minimum,serta berat maksimum dan minimum yang sama. Sebagian besar individu yang tertangkap pada kawasan Muara dan Tambak memiliki interval ukuran lebar karapas dan berat yang sama yaitu antara 87 – 98 mm untuk interval lebar karapas dengan interval berat antara 106 – 117 gram. Pola pertumbuhan kepiting bakau di ketiga lokasi penelitian menunjukkan bahwa pola pertumbuhan alometrik negatif yaitu pertambahan lebar karapas lebih cepat dibandingkan dengan pertambahan bobot atau berat tubuh. Pola pertumbuhan kepiting bakau baik jantan maupun betina dalam penelitian ini bersifat allometrik negatif (b< 3)
