<![CDATA[Meiofauna were organisms that live in the interstitial. Synonyms were meiobentos. Meiofauna can also be interpreted as a small group of metazoans that sits between microfauna and macrofauna. This was caused by a very small body size and position was hidden in the sediments and did not provide direct benefits to humans (economic benefits). Meiofauna generally known only by scientists who pursue marine biology and ecology. This study aimed to determine the ecological water quality index based on the island of interstitial meiofauna Pannikiang, Barru district. The results showed that the class was the class that dominates the nematode composition and density of meiofauna in Pannikiang Island. Nematodes were very instrumental in the classroom enrich and enhance the productivity of aquatic ecosystems. Based on the ecological value of the index, the index of diversity (H'), Uniformity (E), and dominance (D) showed that P. Pannikiang have good water quality with the diversity of species and the spread of the number of individuals of each species were equal, a unified community and did not find any species that dominate the surrounding waters. Meiofauna ecology index indicates that the water condition in P. Pannikiang not currently experiencing a very severe ecological pressure, meaning that in a stable community structure, environmental conditions is excellent. Therefore, we need public participation and coordination among agencies in the District. Barru to maintain the condition of these waters.]]>

<![CDATA[The influence of processing method of tire tuber (Amorphophallus sp.) toward the level of calcium oxalate at Faculty of Mathematics and Natural Sciences, State University of Makassar was to finding out the effect of tuber processing methods tire against calcium oxalate and know the best way of processing. This research conducted in experiment central laboratory of the Ministry of Health, Indonesia, and Makassar. This research consisted of the dependent variable in the form of calcium oxalate in the tuber tire and independent variables such as processing methods. Samples were tire tuber (Amorphophallus sp.) processed by boiling it (A1), salt-water immersion (A2), and wood ash (A3). The research data obtained using titrimetry. Data were analyzed using inferential analysis technique and LSD test at 0.05 significance level. Average-content of calcium oxalate of tire tuber weighing one gram for A0, A1, A2, and A3 respectively was 0.056%, 0.008%, 0.034%, and 0.040%. From the data, it appears there was the influence of processing methods, both those treated with boiling water immersion salt and wood ashes, on serum calcium oxalate in the tuber tire. The most effective way of processing was to reduce or minimize calcium oxalate in the tuber tire processing by boiling. ]]>
