Abstract

Tofu industry liquid waste, which is still contains high concentration of organic materials, is one of the causes of pollution in environment. On the other hand, clay can be used as adsorbent and easily to be obtained. The aim of this study was to reduce ammonia, nitrate, and nitrite concentration on liquid waste of tofu industry using colected clay from three different locations at laboratory scale. Clay was collected from Kalukubula, Beka and Sibowi villages at Sigi District Central Sulawesi Province. Each clay was activated by 0.1 M HCl, 0.1 M NH4Cl or 0.1 M NaOH. The result showed that clay from Beka village has highest capacity to reduce nitrate, nitrite and ammonia concentration on liquid waste of tofu industry. Clay from Kalukubula village was better as absorbent than clay from Sibowi village.  The strength of activator in increasing clay adsorptive was followed this order: NaOH < NH4Cl < HCl. Clay from Beka Village when activated by HCl 0.1 M, it could reduce 47.52%, 54.00% and 58.89% of amonia, nitrate and nitrite concentration, respectively.

Abstract

Coconut shell charcoal as an agricultural waste material is high enough containing carbon. This underlying that coconut shell charcoal can be used as raw material of activated charcoal in purification of used cooking oil. Activator of the charcoal was  45% ZnCl2 in various time of heating at 110oC oven , i.e. 2 hours, 2.5 hours, 3 hours; 3.5 hours and 4 hours, then it was followed by various contact time in purification of used cooking oil, that were 1 hour, 2 hours , 3 hours, 4 hours and 5 hours. The obtained results showed that the best time to be used warming was 3.5 hours, which the iodine absorption was 626.25 mg/g. While the optimum contact time for adsorption was 2 hours. Clarity test was done based on several parameters, namely thiobarbiturat (TBA) value, peroxide value and free fatty acid (FFA) content. The results were 0.471042 mg/kg of malonaldehida, 9.1 meq/kg and 0.17152 % FFA respectively. Furthermore, colour test was done by using  spectrophotometer, it was obtained the T value of 1.62%.

Abstract

Drug Related Problems (DRPs) is an unexpected incident patients experience consequences or unforeseen consequences could potentially interfere with drug therapy to therapy outcomes. Dengue Hemorrhagic Fever (DHF) is one of diseases that occur in children and have a great chance to be the occurrence of DRPs. This study aims to find out the extent of potential DRPs in the incidence of DHF in children patients at the RSUD (public hospital) Undata Palu. This research was non experimental study using a descriptive retrospective study. The research was conducted by collecting data from the medical records of children patient (1-12 years old)  undiagnosed DHF at RSUD Undata Palu. The data analyzed includes unnecessary drug therapy, wrong medicine, subtherapy dose and overdose. Based on the results of the study, we obtained that from 103 patients who met the criteria there were total of around  171 cases of  DRPs cases, i.e. 103 cases (57.89%) was clasified as unnecessary drug therapy category, 25 cases (14,62%) was categorised as wrong medicine, 39 cases (22,81%) was over dose categories, and 8 cases (4,68%) was subtherapy dose category. The most often DRPs incidents occurs in this study were unnecessary drug therapy should be as large as 57,89 % of the total cases of DRPs.

Abstract

Research about mercury translocation (Hg) into the leaf of Amaranthus Spinosus L from polluted soil has been carried out. The research aim was to know influences of  remediation time on the abilty of  mercury absorptions , knowing the concentration of mercury distribution in the leaf of A. spinosus L and abilty of A. spinosus L as hyperacumulator plant to the mercury. Remediation times used 14 days, 21 days and  42 days. The consentration of Mercury on the growth medium were 25 ppm, 50 ppm, 75 ppm, and 100 ppm. The result showed  that the time of maximum absorptions were at remediation times of  14 days by mercury acumulation of 70.6901 mg/kg DM (Dry Measure). This value indicated that A. spinosus L. is hyperacumulator to the mercury and it have a potential as phytoremediator on the area that contaminated by mercury.

Abstract

Diarrhea is one of the main causes of child morbility and mortality in developing countries. Giving zinc and probiotics to children who get diarrhea, it can give positive impact on the incidence of diarrhea. This research aimed to evaluate the use of zinc and probiotics in treatment of children diarrhea. This research was conducted by using prospective method to children diarrhea in children?s ward Catelia at RSUD Undata Palu from June to September 2013. The subject on this research were divided into 2 groups, test and control group. The test group received therapy Oral Rehydration Salts (ORS),  in combination to zinc ? probiotic treatment, and the control group only received ORS. Observed variable are the change of stool consistency,  frequency, diarrhea duration, and lenght of stay. The result of changing stool consistency in test group was better than it in control group. The mean frequency of diarrhea while out in the test group was 1,27 ± 0,45 and it in control group was 1,53 ± 0,56. Lenght of stay in treated group (3,27 ± 1,26) was shorter  than it in control group (3,77 ± 1,00). The use of zinc and probiotics for children diarrhea patients have significant effect on stool consistency, diarrhea frequency, diarrhea duration and lenght of stay (p=0,000).

Abstract

This research was about the useofactive charcoal of the banana peel (Musa normalis) as adsorbent to degrade peroxide and free faty acid of the used cooking oil. The aims of thisresearch was to determine the best rasio of active charcoal of the banana peel as adsorbent, and the best concentration of NaOH as activator to reduceperoxideand free faty acid of the used cooking oil. This research used 5 level oftreatmentswhich based on CRD, the ratio variation were 2.5, 5.0, 7.5, 10.0 and 12.5 % and the concentrations of NaOH variation were 0.125, 0.25, 0.5, 1 and 2 N. The result showed that the best ratio was occurred in the 10.0 % and the concentration of 1 N NaOH. This value indicated that the banana peel was an adsorben, which can be used inincrease quality of the used cooking oil.

Abstract

Dengue fever is one of disease which can be transmited by Aedes aegypti. However the prevention on this disease is become global concern. One approche that can be done is by controlling of mosquito population. Related to that issue, this study was done by an application of potryagyn maximum principle in optimal control theory, based on Sterile Insect Technique (SIT). It can be done biologically by introduction of male sterile mosquito (mutan which can be produce by mutagen such as gamma radiation) into the population. It expected that the number of sterile mosquitos will increase by the time. Our result showed that the population of juvenile, immature male and female mosquitos,  fertile male and female, and also sterile male mosquito on the population will grow and reach the stagnan condition after 50 days. Those data indicate that the number of sterile male will increase without any reduction of the population itself. If this method be combained with insecticide chemical method, the population of mosquitos can be reduced/eliminated efectively.

Abstract

Diabetes mellitus (DM) is a metabolic disease prevalence increasing year by year. DM disease characterized by hyperglikemia that caused by abnormalities of insulin secretion, insulin activity or both. DM consists of two main types, namely DM type 1 and type 2. This research aims to know the profile of the treatment of type 2 DM in Undata hospital using method a retrospective medical record by noting that in accordance with the criteria of inclusion and exclusion. Among 147 population, 69 was taken as samples, then its characteristic were described based on each variable, resulting in a frequency distribution and proportion of each variable. The results showed that the most common therapy for type 2 DM was rapid acting insulin (novorapid), and the most common used of oral antidiabetic was metformin, and is most often treatment was combination of metformin and glimepirid.
