Abstract

Kegiatan pertambangan marmer di Tulungagung , Jawa Timur semakin marak. Keberadaan industri ini selain memberi dampak positif bagi perekonomian, juga memberi dampak negatif bagi organisme akuatik. Kandungan kapur dan potassium dalam limbah marmer dapat mempengaruhi kesehatan makhluk hidup. Semakin besar skala kegiatan pertambangan, makin besar pula dampak yang ditimbulkan. Studi ini dilakukan untuk menentukan besarnya toksisitas akut (LC50) dan efek dari limbah marmer pada ikan dan tumbuhan air yang hidup di sungai. Uji toksisitas ini dilakukan pada ikan mujair (Oreochromis mossambicus) dan tumbuhan anacharis (Egeria densa). Pengujian dilakukan secara statik di laboratorium untuk mencari range finding toxicity. Variasi tes I untuk ikan mujair dan tumbuhan anacharis adalah 0%, 20%, 40%, 60%, 80%, dan 100% volume toksikan. Variasi tes II bervariasi mulai dari 12% - 60% volume toksikan secara duplo. Dari tes II didapatkan kisaran untuk uji toksisitas akut untuk ikan mujair dan anacharis terhadap volume toksikan. Dengan perhitungan Litchfield – Wilcoxon, maka LC50, 96jam untuk ikan mujair dan anacharis dapat ditentukan ================================================================================================== Marble Mining activities have become very common in Tulungagung, East Java. These industrial existences are not only giving a positive implication for economy, but also presenting negative side for the ocean organism. The composition of limestone and potassium in the marble waste can affect the wellness of human beings. The larger scale of mining activities, the greater impact will be posed. This study case is to determine the amount of toxicity (LC50) and the effect of marble waste in fish and hydrophyte which is living in the river. This toxicity experiment was carried out on Tilapia Fish (Oreochromis Mossambicus) and Anacharis Plant (Egeria Densa). The experimentation was conducted statically in the Laboratory searching for range finding toxicity. Variety Test I for Tilapia Fish and anacharis plant are 0%, 20%, 40%, 60%, 80%, and 100% based on the volume of toxicant. On the other hand, variety test II ranged from 12% to 60% by volume of toxicant in duple. According to test II, it is clearly shows the range of toxicity tests for Tilapia Fish and Anacharis Plant toward the volume of toxicant. Furthermore, by using the calculation of Litchfield - Wilcoxon, so that LC50, 96 hours in Tilapia Fish and Anacharis Plant can be resolved
