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
