Abstract

Salah satu dampak negatif modernisasi dan industrialisasi adalah pencemaran lingkungan. Perairan merupakan salah satu lingkungan yang paling terbebani bahan pencemar karena banyaknya limbah rumah tangga maupun industri yang akhirnya masuk ke lingkungan perairan. Salah satu bahan pencemar perairan yang paling membahayakan adalah logam berat karena bersifat non-biodegradable. Oleh karena itu perlu upaya penanganan maupun pencegahan terhadap bahan pencemar tersebut. Pengolahan limbah secara fisiko-kimiawi dinilai mahal, menurunkan biodiversitas, banyak lumpur yang dihasilkan, dan kurang efektif pada konsentrasi logam di bawah 50 mg/l. Bioremediasi merupakan salah satu metode perbaikan lingkungan yang lebih ramah lingkungan karena menggunakan agen hayati seperti bakteri, jamur, protista, dan tanaman. Chlorella vulgaris Beijerinck merupakan mikroalga bersel satu yang banyak tumbuh di perairan tawar dan laut, telah dimanfaatkan masyarakat sebagai bahan pakan, suplemen, biofuel dan bioremediasi. Penelitian ini bertujuan untuk menguji potensi C. vulgaris sebagai agen bioremediasi terhadap cemaran logam berat Cd dan Pb skala laboratorium. Penelitian menggunakan Rancangan Acak Lengkap (RAL). C. vulgaris ditumbuhkan dalam media kultur yang telah diberi pupuk Walne selama 76 hari. Media kultur ditambah ion logam Cd dan Pb dengan 3 konsentrasi yang berbeda yaitu  1 ppm, 3 ppm, dan 5 ppm, masing-masing 3 kali ulangan. Medium kultur tanpa penambahan logam dianggap sebagai kontrol. Kandungan logam berat dalam medium dan dalam sel C. vulgaris diukur dengan AAS. Hal yang diamati dalam penelitian ini adalah pola pertumbuhan populasi C. vulgaris, persentase penurunan logam Cd dan Pb oleh C. vulgaris, besarnya akumulasi logam dalam C. vulgaris, serta nilai Bioconcentration Factor (BCF). Berdasarkan penelitian tersebut terbukti bahwa C. vulgaris terbukti mampu menurunkan konsentrasi ion Cd dan Pb dalam perairan. Prosentase penurunan konsentrasi ion Pb dalam media kontrol, 1 ppm, 3 ppm, dan 5 ppm berturut-turut  70%, 80%, 62%, dan 52% sedangkan dalam media Cd pada konsentrasi serupa berturut-turut 67%, 79%, 56%, dan 51%. C.  vulgaris mampu mengakumulasi  Cd lebih besar daripada Pb. Berdasarkan nilai BCF  terhadap  Cd maupun Pb, C. vulgaris tergolong akumulator logam.   Kata kunci : logam berat, bioremediasi, Chlorella vulgaris,  bioakumulasi.

Abstract

Aquaculture is one of important economic activity in Indonesia. The main problem in aquaculture is the low water quality such lower oxygen level . Ceratophyllum demersum is one of aquatic plants that is hypothesized capable in increasing oxygen level through photosynthesis. However the growth of C. demersum it self will consume oxygen from the water  through respiration. The aim of this study is to measure oxygen production and consumption by C. demersum at different density level. From this data, we will understand the potency of  C.demersum as bioaerator to supplay oxygen in the water. This experiment was designed using Completed Randomized Designed (CRD). Three density level of C. demersum was apllied as treatment. They were 100g/100L, 200g/100L dan 300g/100L. Each treatment was replicated by 4 times. Results indicated that in density of 300g/100L produced the highest oxygen level ( 1,65 ppm). The highest growth rate of C. demersum was resulted by density level of 200g/100L.

Abstract

Ammonia, nitrite and nitrate accumulation in shrimp pond is a big problem for shrimp survival, since these compunds are toxic. We propose to solve the problem by addition of seaweeds, Sargsasum plagyophyllum and Gracilaria verrucosa to reduce ammonia, nitrite and nitrate. The aim of this research is to evaluate the effectivity of Sargassum and Gracilaria in reducing ammonia, nitrite and nitrate content in the water. This research was conducted in brackish water shrimp pond, using 1m x 1m x 1.2m plastic enclosures as models. Plastic enclosures without seaweeds were served as controls. All treatments were repeated 4 times. We observed the reduction of ammonia, nitrite and nitrate content weekly. Results indicated that both sargassum and Gracilaria were capable in reducing this inorganic nitrogen content. However, Gracilaria was more effective in the role of ammonia, nitrite and nitrat reduction compared to Sargassum.

Abstract

Penambahan arang dan abu sekam telah banyak diaplikasikan terhadap tanah pertanian maupun tanah pada lahan-lahan marginal. Arang dan abu sekam dapat memperbaiki sifat fisik tanah dan meningkatkan kesuburan tanah. Penelitian ini bertujuan untuk mengetahui efektifitas penambahan arang dan abu sekam pada berbagai proporsi yang berbeda terhadap permeabilitas dan porositas tanah liat, serta pertumbuhan kacang hijau (Vigna radiata L). Hasil penelitian menunjukkan bahwa penambahan arang dan abu sekam  dengan proporsi yang berbeda tidak dapat meningkatkan permeabilitas, porositas tanah liat, dan berat kering akar. Tetapi, penambahan arang dan abu sekam dengan proporsi yang berbeda dapat meningkatkan panjang akar lateral dan berat kering tajuk. Penambahan arang sekam pada proporsi penambahan 50%  menghasilkan akar lateral terpanjang, yaitu 67,01 cm. Penambahan arang dan abu sekam dapat meningkatkan berat kering tajuk. Berat kering tajuk tertinggi 1,26 gr dihasilkan oleh penambahan abu sekam. Penambahan arang dan abu sekam dengan proporsi yang berbeda tidak dapat memperbaiki sifat fisik tanah liat, tetapi dapat meningkatkan pertumbuhan kacang hijau, terutama panjang akar lateral dan berat karing tajuk.Kata kunci :  arang sekam, abu sekam, permeabilitas, porositas, pertumbuhan kacang hijau

Abstract

We investigated the use of Eucheuma spinosum and Halimeda sp as a trap for the Rabbitfish, Syganus sp. The aim of this research is to maximize the yield of Syganid by fisherman. Result s indicated that using seaweeds as a trap, 45% of harvested fish was dominated by Syganus sp. The presence of seaweeds lead toaccumulation of Syganid. In using combination of seaweeds, i.e: Eucheuma spinosum + Halimeda sp at the distance of 10cm give the highest yield of fish. To maximize the traps, we have to also consider in using other technique such as arrangement of trap position and hole size of the traps.
