Abstract

Aspartame is safe for consumption according to the prescribed ADI, but this artificial sweetener is not nutritious or does not contain calories so it is not recommended to be consumed during pregnancy. This study was to analyze cariometric effect of aspartame doses in the development of fetal mice (Mus muculus L.). The type of research used was experimental laboratory research on 24 adult mice with 4 treatment groups, control, aspartame dose 13 mg / Kg BB, 39 mg / Kg BB and 78 mg / Kg BB. Data was analyzed using SPSS 16 with one way ANOVA. Based on the results of the study there were changes in the number and weight of the fetus due to aspartame doses, there was no change in fetal length due of aspartame dose variations. Consumption of aspartame during pregnancy should be avoided because it can cause teratogenic effects. For further research, it is necessary to observe the morphology and histology of the fetus which is expressed by aspartame to determine the types of congenital abnormalities.

Abstract

Fulfillment of water quality requirements is absolutely necessary to fulfill primary human needs, especially drinking water and clean water sources, both in quantity and quality. Study of the underground caverns found the fact that in terms of quantity of water availability in the reservoir is able to meet the needs of residents of the Rengel District, but qualitatively not yet known the water quality in the reservoir. The purpose of this study was to measure the water quality of underground caves in caves which include temperature, turbidity, TDS, DO and pH. The method used in this study is a qualitative method to measure the value of water quality. The research sample was taken with three repetitions for data validity. The sampling location is the underground cave system with a length of 1 km, sample points include dark zone 1, dark zone 2, dark zone 3, and dim zone. Measurements were taken in the laboratory. The results of the study showed that the average values for temperature, turbidity, TDS, DO and pH were 26.7; 1,9; 348.2; 1,6; and 7.1. The conclusion obtained from this study is that all indicators except DOs meet environmental quality standards set by the government.

Abstract

Zn merupakan logam berat yang banyak digunakan untuk memenuhi kebutuhan industri. Meningkatnya penggunaan Zn menyebabkan pencemaran air. Untuk mereduksi hasil buangan dari industri yang menghasilkan Zn dapat dilakukan dengan cara teknik fitoremediasi. Pada penelitian ini, fitoremdiasi yamg dilakukan yaitu dengan memanfaatkan tanaman Apu-Apu (Pistia stratiotes) sebagai tanaman fitoremediator. Penelitian ini dilakukan dengan tujuan untuk mengetahui efisiensi penyerapan logam berat Zn oleh tanaman Apu-Apu dengan variasi jumlah tanaman yang berbeda. Variasi jumlah tanaman yang digunakan yaitu 10 dan 15 tanaman dengan waktu tinggal selama 10 hari dan dengan konsentrasi awal 11,02 ppm. Hasil penelitian ini menunjukkan bahwa pada reaktor B memiliki efisiensi removal logam berat Zn sebesar 83,85% dan pada reaktor C memiliki efisiensi removal sebesar 79,50%.Kata Kunci: Logam Zn, Fitoremediasi, Pistia stratiotes, Sistem Batch

Abstract

Water pollution can become dangerous if consumed. River could be polluted with some materials namely heavy metal of chopper (Cu). Heavy metals that are accidentally consumed by human body through the skin surface, some through the respiratory or digestive tract and then accumulate in the body over time. To make an early detection of heavy metal and water quality in water bodies, some animals or plants were used. Several types of crustaceans such as Artemia salina and Daphnia magna or commonly referred to as bio indicators. This study analyze comparison of acute toxicity test that represented by LC50 value of Cu in Artemia salina and Daphnia magna. From the research result it was found that Artemia salina and Daphnia magna gave a toxic effect with LC50 values of 11.78 ppm and 7.87 ppm, respectively.

Abstract

Meningkatnya kegiatan industri dapat menimbulkan dampak negatif yang dapat membahayakan lingkungan seperti terjadinya pencemaran akibat adanya logam berat pada air. Salah satu metode untuk menurunkan kadar logam berat pada air yakni dengan adsorpsi. Proses adsorpsi dapat dilakukan menggunakan adsorben sebagai zat penyerap dengan memanfaatkan limbah organik. Tujuan dari penelitian ini adalah untuk mengetahui besarnya konsentrasi logam timbal yang terserap dalam proses adsorpsi menggunakan adsorben limbah kulit pisang kepok dalam reaktor kontinyu dan menganalisa pengaruh variasi yang digunakan pada proses adsorpsi. Penelitian ini dilakukan secara eksperimental dengan menggunakan variasi laju alir (2,4, dan 6 ml/mnt) dan variasi volume adsorben (15, 20, dan 25 cm). Data hasil adsorpsi akan diolah menggunakan SPSS untuk dilakukan uji statistika menggunakan two way anova. Prasyarat data untuk uji two way anova adalah data harus berdistribusi secara normal dan bersifat homogen. Hasil dari penelitian  menunjukkan bahwa proses adsorpsi menggunakan adsorben limbah kulit pisang kepok dapat menyerap timbal sebesar 7,118 mg/l yakni dari kadar awal sebesar 7,401 mg/l menjadi 0,282 mg/l dengan tingkat efisiensi sebesar 94,5% dan terdapat pengaruh yang signifikan terhadap variasi laju alir pada proses adsorpsi.
