Chronic sediment toxicity tests could be used to evaluate the effects of sediment on critical stages in the life of an organism like invertebrate larvae and microalgae. Microalgae play an important role in aquatic ecosystem due to their role as producer in food chain producing organic matter and oxygen through photosynthesis process. This paper aimed to assess sediment quality of Semarang water using chronic sediment toxicity test. Research was conducted by testing 13 sediment samples from Semarang coastal region in August, 2010. Results showed that sediments exposed for 96 hours were still able to stimulate the growth of C. gracilis eventhough the copper concentration was above standard value provided by the CCME. The conclusion from this research was that sediment in Semarang still in good condition and can support growth of C. gracilis as primary producer. Chronic sediment toxicity test using C. gracilis could be combined with heavy metal measurement for sediment quality asessment. Keywords: sediment, bioindicator, diatomae, C. gracilis, chronic toxicity, Semarang

Lapangan X terbagi menjadi 3 area yaitu North X, Middle X dan South X. Untuk mengoptimalkan perolehan minyak, kegiatan injeksi air dilakukan setahun setelah mencapai puncak produksi, pada tahun 1989. Salah satu cara evaluasi kinerja injeksi air adalah dengan grafik RF vs PVI yang dapat membantu analisis kinerja injeksi air tiap area pada suatu lapangan secara individual serta dibandingkan dengan kinerja injeksi air pada rata-rata lapangan. Area North X memiliki kinerja injeksi di bawah rata-rata lapangan, area Middle X dan South X berada di atas rata-rata lapangan. Untuk analisis heterogenitas reservoir, dilakukan perhitungan Variasi Permeabilitas Dysktra-Parson, Vdp. Area North X mempunyai heterogenitas tertinggi yaitu 0,998, area Middle X dan South X berturut-turut sebesar 0,75 dan 0,85. Pada perhitungan volumetric sweep efficiency, Evw dilakukan untuk mengetahui presentase reservoir yang telah tersapu oleh fluida injeksi dan dapat mencerminkan potensi perolehan minyak tambahan secara kuantitatif pada bagian reservoir yang belum tersapu. Hasil evaluasimenunjukkan bahwa area North X memiliki Evw paling rendah yaitu 66,14%. Evw area Middle X dan South X beruturut-turut sebesar 76,85% dan 88,58%. Dapat disimpulkan bahwa heterogenitas reservoir berpengaruh terhadap volumetric sweep efficiency dan akhirnya berpengaruh terhadap kinerja injeksi air pada lapangan X. Area North X dapat dioptimasi lebih lanjut.
