Abstract

Dalam rangka memperbaiki kualitas perairan Sungai, vetiver (Chrysopogon zizanioides) telah ditanampada kawasan bantaran Sungai CIkapundung selama 63 hari. Dua wadah dialiri dengan sumber air yangberbeda, yaitu air sungai dan air tanah (sumur). Produksi biomassa diukur setiap 20 harian sekali,dengan fokus pengukuran pada pertumbuhan tunas dan akar vetiver. Secara umum, pertumbuhan tunasdan akar vetiver yang ditanam pada wadah yang dialiri air sungai tumbuh lebih baik (panjang) daripadavetiver yang ditanam pada wadah yang dialiri air tanah. Data pengukuran berat kering biomassamenunjukkan bahwa hingga waktu ketiga pengambilan contoh, perpanjangan akar lebih cepat daripadaperpanjangan tunas. Data-data tersebut menunjukkan bahwa vetiver memiliki kemampuan yang sangatbaik dalam memanfaatkan nutrien yang berasal dari limbah organik Sungai Cikapundung. Oleh karenaitu, vetiver dapat diusulkan sebagai tanaman untuk aktivitas fitoremediasi di kawasan bantaran SungaiCikapundung. Pertambahan panjang akar vetiver yang lebih cepat daripada pertambahan panjangtunasnya juga dapat dimanfaatkan sebagai tanaman anti longsor di sepanjang kawasan bantaran sungai.

Abstract

Water quality index (IKA) is one tool to quickly predict the environmental quality status of an ecosystem or region to obtaining an alternative of the future management. Toanalyze the status of these indices utilize only data of environmental parameters that have been established as a key parameter determining the IKA. From the analysis of the mining area of PT KPC IKA with key parameters TDS, DO, COD, nitrogen (N) and phosphorus. (P) derived from the water quality of agricultural ecosystems, industry / mines and residential showed an index value of less well with thecategory (54.6163) on the interval 40 ≤ IKA <60. The low index value is proportional to the low value of ecosystem quality index industry / mining IKA (I) with a value of 45.82with categories of less well on the interval 40 ≤ IKA <60. Consider, that the index value of ecosystem quality residential IKA (H) and agricultural ecosystem quality index IKA (P) with good and excellent categories, then the ecosystem of industry / mining is the focus that needs to be considered for improved management efforts.

Abstract

Penelitian ini bertujuan mencari alternatif limbah organik sebaga bahan baku pembuatan media tumbuh mikroalga Chlorella sp, dimana bahannya melimpah, mudah diperolehdengan harga lebih kompetitif. Beberapa literatur menyebutkan bahwa rumput laut banyak tersebar di perairan laut Nusantara dan memiliki kandungan nutrien (makro dan mikro) yang tinggi, sehingga limbahnya pun diperkirakan masih mengandung unsureunsur yang dibutuhkan untuk pertumbuhan mikroalga. Hasil analisa nutrien pada limbah padat rumput laut, menunjukan kandungan mikro nutrien yang tinggi, kecuali unsurnitrogen (N) dan posfor (P) yang tersedia relatif rendah, namun masih layak digunakan sebagai media mikroalga. Hasil uji pemanfaatan limbah industri pengolahan limbahrumput laut (LR) dan limbah rumput laut yang sudah diperkaya dengan unsur N (LRP) dibandingkan dengan media F/2 Guillard (FG) menunjukan bahwa limbah rumput laut LRP dapat dimanfaatkan sebagai media kultur mikroalga yang ditunjukan oleh tingkat kepadatan dan laju pertumbuhan mikroalga lebih baik dibandingkan dengan media FG maupun LR (LRP>FG>LR).Dari hasil pembahasan, dapat disimpulkan bahwa media kultur asal limbah proses pengolahan rumput laut LRP membuktikan bahwa limbahorganic dari proses pengolahan rumput laut dapat digunakan sebagai bahan baku pembuatan mediam tumbuh mikroalga, khususnya Chlorella sp.
