Hubungan Variabilitas Iklim (Curah Hujan, Suhu, Dan Kelembaban) Dengan Kejadian Diare Di Kota Denpasar, Provinsi Bali

The variability of some climate elements could be expected to affect the increase of diarrheal diseases. This study aims to determine the relationship between variability of climate elements and the incidence of diarrhea in the city of Denpasar. The variables analyzed were the elements of the climate (rainfall, rainy days, temperature, and humidity) and the number of diarrheal cases from 2010 to 2014. The climate data and data incidence of diarrhea are from Updated Model of Surveillance System Impact of Climate Change on Health Research and Development in 2014. Data analysis was performed to generate univariable, bivariables, and multivariables data using Microsoft Excell software. The analysis showed that during the period 2010 until 2014 increased rainfall compared with the data from 2008, the highest incidence of diarrhea in Denpasar are 10,823 cases (2011). The multivariate analysis showed that there is a significant relationship between diarrhea and rainfall, rainy days, and humidity (P <0.05, r2 = 0.703; lag time 1). It can be concluded that there is a relationship between incidence of diarrhea and climate variables of 1 week earlier. There is a need to increase public awareness in maintaining environmental sanitation and hyigienic conditions during a peak of rainy and dry seasons

Synthesis of Mg/Al Hydrotalcite by Using Low Supersaturated Precipitation Method with Variation of Mole Ratio

This research aims to synthesize Mg/Al hydrotalcite with mole ratio variations of Mg/Al precursor through low supersaturated precipitation method. Mg/Al hydrotalcite was synthesized with Mg/Al mole ratio variation of 1:1, 2:1, 3:1, and 4:1. Mg/Al hydrotalcite was synthesized using NaOH and Na2CO3 base solutions. The mixture of precursor was stirred for 2 hours then treated by hydrothermal at 100 °C for 4 hours. Results of the synthesis Mg/Al hydrotalcite with mole ratio variations is a white powder. The formation of the structure of Mg/Al hydrotalcite showed by certain peaks in the FTIR spectra and XRD diffractogram.The results of data analysisshowed that variation of mole ratio Mg/Alcauses a shift of peak in the XRD diffractogram shifted towards the left along with a comparative increase in mole ratio Mg/Al, but the main functional groups on the compound Mg/Al hydrotalcite increasingly formed with better

Kadar Logam Berat Di Lingkungan Wilayah Tambang, Nusa Tenggara Barat (Heavy Metals Concentration in Mining Area at West Nusa Tenggara)

The aim of research on heavy metals concentration in mining area at West Nusa Tenggara is to find out about environmental pollution caused by the mining activities. The research was done by analyzing heavy metals, such as As, Hg, Cd, Cu, Fe and Mn in river water, sediment, drinking water, fish, oyster, com, and vegetables using Atomic Absorption Spectrophotometer (AAS). The result shows that heavy metals concentration in river water and sediment are still in normal range according to River Quality class D on PP 20/1990. Heavy metals concentration in drinldng water is at normal range according to Regulation of the Ministry of Health (Permenkes) 907/2002 except for Mn from Sekongkang and Benette. Heavymetals in fish are normal according to regulation of the ministry of health specifically on Food and Drug No. 03725/B/SK/VII/89 except for As. Mean rate of As in fish and oyster around the mine is 0.959 mg/kg and 53.278 mg/kg. From the control area, mean rate for As is 1.666 mg/kg (Regulation of the Ministry of Health special on Food and Drug standard is 1.0 mg/kg). Heavy metals in rice, com, and vegetables are stillin normal range except for Cu in vegetables. Mean rate for Cu in vegetables at mining and control area are 6.116 mg/kg and 6.000 mg/kg (Regulation of the Ministry of Health specifically on Food and Drug standard is 5.0 mg/kg). Further research in heavy metals monitoring, especially in water and fish is needed
