Abstract

Chlorella sp dikenal sebagai mikroalga yang mampu hidup di berbagai badan air, termasuk badan airpenampung limbah cair. Kajian ini dilakukan dengan tujuan untuk mengetahui kemampuan adaptasiChlorella sp pada limbah cair industri susu, yang jika terurai menghasilkan nutrien untuk pertumbuhanChlorella sp. Kajian dilakukan dengan memelihara Chlorella sp pada media F/2 Guallard, limbah cairindustri susu (LS) dan limbah cair industri susu yang diperkaya dengan nitrogen setara nitrogendalam F/2 (LSP). Kajian ini mengungkapkan bahwa Chlorella sp tumbuh paling baik di media limbahsusu yang diperkaya dengan nitrogen setara F/2. Media tersebut (LSP) menghasilkan kepadatan dankonsentrasi Chl-a, serta kandungan Chl-a per individu Chlorella sp yang lebih tinggi daripada mediaF/2 dan LS. Mengingat limbah susu yang tidak diolah dengan baik dapat menimbulkan pencemaranbagi lingkungan perairan sekitar industri itu berada, maka perlu dipertimbangkan kemungkinanpemanfaatan Chlorella sp pada pengolahan limbah industri susu di tingkat lanjutan, sebelum limbahdibuang ke badan air.

Abstract

Air, baik air tanah maupun air permukaan merupakan sumber kehidupan yang tidak dapat tergantikan oleh apa pun dan tanpa air, manusia, hewan dan tanaman tidak akan dapat hidup terutama sebagai air minum. Tetapi dalam pemanfaatannya, masih banyak yang tidak sesuai dengan peruntukannya ataupun mempergunakan sampai diluar batas, sehingga disatu sisi banyak yang terbuang dengan sia-sia tetapi dilain sisi banyak yang membutuhkan. Penggunaan air selama dasa warsa terakhir ini meningkat disebabkan oleh beberapa faktor, antara lain oleh kegiatan manusia yang semakin bervariasi, pertambahan jumlah penduduk yang meningkat, maka jumlah air untuk kebutuhan manusia juga meningkat dan hal ini berpengaruh terhadap kualitas air. Selain itu juga berpengaruh terhadap keterbatasan air dan kondisi alam. Untuk itu diperlukan suatu system pengelolaan air yang sangat baik dengan memperhatikan akan kondisi alam dan ketersediaan akan air sehingga tercapai suatu pengelolaan yang sesuai dengan tata kelola air. Kata kunci : air, pengelolaan air, lingkungan AbstractWater, both ground water and surface water is the source of life that can not be replaced by anything and without water, people, animals and plants will not be able to live.But in its utilization, there are still many who are not as intended or use to beyond the limit, so that on one hand many are wasted in vain, but on the other side of the many in need. Use of water during the last decade has increased due to several factors, among others,by human activities increasingly varied, the number of population increases, the amount of water for human needs has also increased and this contributes to water quality. It also affects the limitations of water and natural conditions. It required a water management system is very good with attention to natural condition sand the availability of water in order to reach an appropriate management of the water governance and the availability of clean wateris needed.  Keywords: water, water management, environment

Abstract

Pencemaran sungai akibat akumulasi limbah domestik dan industri merupakan tantangan yang serius bagi kelestarian hidup biota perairan. Limbah domestik/rumah tangga yang sering dibuang ke perairan dapat mengganggu ekosistem yang ada di perairan tersebut. Sejauh ini berbagai upaya sudah mulai dilakukan industri dengan pembuatan instalasi limbah terpadu, namun upaya tersebut masih belum maksimal karena rendahnya kesadaran masyarakat dan lemahnya pengawasan dari instansi terkait. Salah satu upaya untuk mengurangi limbah domestik adalah dengan membuat biology irigation dengan memanfaatkan tanaman talas Colocasiaesculenta. Studi pemanfaatan tanaman air untuk pengolahan air limbah domestik dalam sistem biology irigation ini dilakukanuntuk mengetahui efisiensi penyerapan unsur hara oleh C. esculenta. Metode penelitian yang diterapkan adalah menumbuhkan C. esculenta dalam suatu wadah percobaan race ways yang dialiri air limbah domestic dengan sistem subsurface flow (SSF). Hasilpenelitian menunjukkanbahwa secara fisik C.Esculenta dapat tumbuh lebih baik pada substrat yang mengandung air sungai Cikapundung dibandingkan dengan C.Esculenta yang ditumbuhkan pada substrat yang ditambahkan air sumur. Hal tersebut ditunjukkan oleh perbedaan pertumbuhan panjang dan berat tanaman tersebut. Hasil analisis parameter karbon organik (C-organik), nitrogen (N-kejdahl) dan fosfat (P) pada jaringan tanaman talas (bagian daun dan akar) menunjukkan adanya peningkatan konsentrasi bahan organic dalam jaringan tanaman tersebut yang berbanding lurus dengan pertumbuhan tanaman talas (tinggi dan berat tanaman talas), sebagaimana ditunjukkan oleh konsentrasi penyerapan C sebesar 2000 mg dan N 100 mg selama 63 hari. Kata kunci : Colocasia esculenta, limbah domestik, fitoremediasi.  AbstractPollution of rivers due to the accumulation of domestic and industrial wasteis aserious challenge to the survival ofaquatic biota. Domestic waste/ household is often thrown into the water can interfere waters ecosystems. So far, many efforts have been done such as installation integrated waste treatment, but these efforts are not yet fulfill the requirement due to low awareness and lack of oversight agencies. One of the efforts to reduce domestic wasteis by making use of plant biology irrigation with Colocasia esculenta. Study ofutilization of aquatic plants for domestic wastewater treatment systems biology irrigation was conducted to determine the efficiency of nutrient uptake by C.esculenta. The research method was applied by growing C.esculenta in an experimental container -carrying raceways domestic wastewater system with subsurface flow (SSF). The results showed that physical C.Esculenta may grow well on substrates containing water Cikapundung river compared to C.Esculentagrown ona substrateis added waterwells. This is shown by the differences in growth and weight of the plants. The results of the Laboratory analysis of organic carbon (C-organic), nitrogen (N-kejdahl) and phosphate (P) on the taro plant (the leaves and roots) showed an increase nutrient in plant tissues which is directly proportional to the growth of taro plants (taro plant height and weight), as shown by a concentration of 2000 mg C sequestration and N100 mg for 63 days.  Keywords: Colocasia esculenta, domestic waste, phytoremediation.
