Abstract

Rawa Jombor which located in Klaten have 3 (three) watershed as channels of water in the swamp. These watersheds are Kali Danguran Bajing Watersheds, Kali Gebyok Watersheds and Kali Jayan Watersheds. The existence of the three watersheds that passes through residential areas and agriculture in the suspect may cause sedimentation and increased fertility in Rawa Jombor. To predict rate of sedimentation on each watershed in the Rawa Jombor needed a soil erosion prediction and sedimentation models. One of model that often used is the USLE model. This research aim is to determine decrease of the function of the environment in Rawa Jombor measured from erosion and sedimentation parameters and their impact on Rawa Jombor. This research uses the USLE models to predict soil erosion and Sediment Delivery Ratio (SDR) model to  predict sediment results with the help of software ArcGIS 10.1. The results of both models obtained value erosion in the Kali Danguran Bajing watershed of 15892.39 tonnes / year, Kali Gebyok watershed of 8972.29 tons / year, and Kali Jayan watershed of 5142.95 tonnes/year. Estimation of sediment in the watershed Danguran Bajing is at 3996.94 tons / year, the watershed Gebyok of 2621.70 tons / year, while the Jayan at 1812.37 tons / year. Rawa Jombor terletak di Kabupaten Klaten memiliki 3 (tiga) DAS sebagai saluran masuknya air pada rawa. Ketiga DAS tersebut adalah DAS Kali Danguran Bajing, DAS Kali Gebyok, dan DAS Kali Jayan. Ketiga DAS tersebut melewati daerah permukiman dan pertanian di duga dapat menyebabkan sedimentasi dan peningkatan kesuburan pada Rawa Jombor. Untuk memprediksi laju sedimentasi pada tiap – tiap DAS di Rawa Jombor diperlukan suatu model pemrediksi erosi tanah dan model sedimentasi. Salah satu model yang sering digunakan adalah model USLE. Tujuan penelitian ini adalah untuk mengetahui penurunan nilai fungsi lingkungan Daerah Aliran Sungai di Rawa Jombor diukur dari parameter erosi dan sedimentasi dan dampaknya terhadap Rawa Jombor. Penelitian ini menggunakan model USLE untuk prediksi erosi tanah dan model Sediment Delivery Ratio (SDR) untuk prediksi hasil sedimen dengan menggunakan bantuan software ArcGIS 10.1. Hasil dari kedua model tersebut didapatkan nilai erosi pada DAS Kali Danguran Bajing sebesar 15.892,39 ton/tahun, DAS Kali Gebyok sebesar 8972,29 ton/tahun, dan DAS Kali Jayan sebesar 5142,95 ton/tahun. Perkiraan hasil sedimen pada DAS Danguran Bajing adalah sebesar 3.996,94 ton/tahun, pada DAS Gebyok sebesar 2.621,70 ton/tahun, sedangkan DAS Jayan sebesar  1.812,37 ton/tahun.

Abstract

Lake has an important function as source of water;  maintain biodiversity; source of protein; manage toxicity; device to reduce river flooding; source  of groundwater; device climate; transportation and touris;  medium; and for cultural and religion activities. Semi natural lake of Rawapening has function for hydroelectricity power, irrigation for agriculture, fisheries, and tourism. For maintaning those functions, lake batimetric map is required for limnological study as well as for basic informasi for development lake management. However, there is no batimetric map of Rawapening Lake after1976  lake’s sketch by Goltenboth. Therefore, this survey was conducted in order to update batimetric map of Rawapening. On August 16th, 2008, echosounding was donecfross section and lake edge every 30 second. Recorded data on the GPS then interpolated to the lake depth form in every dot of echosounding.The deepest part of Rawapening Lake was 18 metres, around Bukit Cinta spring. Comparing to Goltenboth sketch, the Rawapening Lake depth was not quite change. North West part of the lake remain has 2-4.7 metres depth. However, based on sedimentation rate, the shallowness lake was very sharply, and predicted that in 2021 Rawapening Lake will full of sediment. Maintaning lake depth is a must to maintain lake’s function.   Key words: batimetri, Danau Rawapening, limnologi

Abstract

Rawa Pening is a semi natural lake which is utilized for hydro-electric power plant,  caged fish culture, irrigation, and tourism. It belongs to one of the fifteen lakes which receives national priority to be saved and preserved because of its very poor condition as a result of eutrophication, sedimentation and degraded water quality. Eutrophication of  Rawa  Pening comes from the Water Catchment Area,  originating from farms, animal husbandry, domestic and industrial waste around the lake, and also from the water body itself, that is from caged fish culture. The fertility criteria of the lake water can be determined on the basis of the abundance and variety of phytoplankton and the total phosphorus content. The aim of this research is to find out the water fertility criteria of Lake Rawa Pening based on the abundance and variety of  phytoplankton, and the phosphorus content. Research began in July 2012 on three stations. Station I is an area with fishcage culture;  Station II is an area without fishcage culture, and Station III is the river inlet or water catchment area. Each station consisted of three different sampling areas. The phytoplankton abundance at the station without  fishcage culture is higher  (19012 ind/l) than at the fishcage culture station (14356 ind/l)  as well as at the inlet station (11058 ind/l), but the diversity index at the no fishcage station is lowest (1.80)  compared to the fishcage culture station (2.32)  and the inlet station (2.05). The fertility criteria of Rawa Pening based on the phytoplankton abundance and P-total  of  its water is eutrophic  going  towards  hypereutrophic.   Keywords : Lake Rawa Pening, Phosphorus, Water Quality, Euthropication

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.
