Abstract

Acute Coronary Syndrome Patients can cause anxiety for the family. Anxiety of ACS family in Aloei Saboe hospital was found to be a family of moderate anxiety of 18 people (81.8%) and a severe anxiety of 4 people (18.2%). This study used the research design of One Group Pretest Posttest Design with 22 respondents. Respondents were given slow deep breathing exercises, given for 15 minutes. The bivariate analysis used is the Marginal Homogeneity Test. The results of the study were obtained before being given treatment, the family with moderate anxiety amounted to 18 people (81.8%) and a heavy anxiety of 4 people (18.2). After being given treatment there was a decrease in the level of anxiety, the family with moderate anxiety numbered 9 people (40.9) and mild anxiety about 13 people (59.1%). The results of the statistical test for marginal homogeneity obtained p values of 0.000 (p<0.05). There is a slow deep breathing effect on decreasing family anxiety level of acute coronary syndrome patients. Further research, slow deep breathing actions can be combined with health education in overcoming the anxiety of families who care for patients in hospitals.

Abstract

Lead exposure (Pb) may aggravate the decrease in serum SOD levels, memory function reduction and social interaction in autism. This study aims to determine the effect of Moringa oleifera on autism models of rat exposed to lead. The five groups of rat exposed to tin were studied: normal rat (C -), autistic rat (C +) and autism rats given 180 mg (T1), 360 mg (T2) or 720 mg (T3) oleifera leaves powder. Lead acetate is given through a filler tube (0.5 gr / kg) and powdered moringa leaves mixed with feed. The results showed that serum SOD levels were lower in autistic rat than normal rat and intake of Moringa olifeifera leaves powder increased serum SOD levels in autistic rats but was not seen in normal rat. The autistic rat had higher lead levels but lower zinc levels, which were not influenced by Moringa olifeira. The social interaction between rats is strongly influenced by unbidden lead with Moringa olifeira, both in normal rat and in autistic rat. Moringa oleifera will increase serum SOD levels in autistic rats but not at normal levels. Moringa olifeira does not protect significantly rat from lead causing less social interaction, nor does it lower serum Pb levels or increase Zn levels. Moringa leaves powder does not affect memory significantly.

Abstract

The objectives of this study were to evaluate the efficacy of MIPC to control the brown planthopper Nilaparvata lugens, one of the most damaging pests of rice in the field and determine the effect of various of its doses on the growth of the fungus B. bassiana. The research was carried out in a rice field and in the Biological Agents Development Laboratory, Department of Pests and Plant Diseases, Faculty of Agriculture, Brawijaya University, Indonesia. The field efficacy test of the MIPC insecticide was conducted by applying 0.5-, 1.0-, 1.5-, and 2.0-kg/ha doses. The insecticidal compatibility test of MIPC with B. bassiana was conducted in 0.5-, 1.0-, 1.5-, and 2.0-g/L doses of MIPC. Application of MIPC insecticide at 0.5-, 1.0-, 1.5-, and 2.0-kg/ha doses had no significant difference in reducing N. lugens population in the vegetative phase (28 to 70 days after planting). The MIPC doses of 1.0, 1.5, and 2.0 g/L were highly toxic or incompatible with the growth of B. bassiana. Meanwhile, a sublethal concentration of MIPC insecticide of 0.5 g/L was non-toxic to B. bassiana. Therefore, this study recommends the use of 0.5 g/L MIPC combined with B. bassiana fungi.

Abstract

The bioremediation system can be improved by using specific bacterial potential as oil-degrading bacteria which microorganisms can use hydrocarbons as a carbon source for their metabolic processes. The aim of this study is to identify R. erythropolis on degradation oil contamination and to obtain indigenous bacteria as new agent bacteria on bioremediation of oil contamination. The polluted water samples from used oil were taken from PPN Prigi, Trenggalek, East Java, Indonesia. The parameters considered were the detection and characterization of indigenous bacteria that degraded used oil. The density of bacteria was analyzed in the interval time of days 0, 2, 4, 6 and 7 and TPH was analyzed at final incubation. The results of this study indicate that the effectiveness of reducing oil concentration was used in testing the potential of bacteria from the highest was Pseudomonas aeruginosa which as indigenous bacteria isolated from water contaminated sites with application cell rate 1×108 cells/ml. It reduced of oil concentration up to 53%, and 1×106 cells/ml reduced oil concentration up to 47%. While, R. erythropolis with application cell rate 1×108 cells/ml reduced 47%. This result was found that Pseudomonas aeruginosa was effectively removed of oil concentration.

Abstract

Each year, approximately 3 million people with coronary heart disease worldwide undergo percutaneous coronary intervention (PCI). Dual antiplatelet therapy (DAPT) with aspirin and P2Y12 inhibitors became the primary therapy for 6-12 months after PCI. DAPT can be continued > 12 months at a high risk of thrombosis. About 9-10% of patients with dual antiplatelet therapy still experience ischemia. The platelet function examination by thromboelastography (TEG). This research is an analytic observational study using a cross-sectional method. This study was conducted in Saiful Anwar General Hospital. Patients were divided into two groups: (1) on-single antiplatelet therapy; (2) on-dual antiplatelet therapy. The outcome measured result of the platelet function test was divided into standard, low platelet function, and platelet hypercoagulability. An analysis of the differences between single or multiple antiplatelet administration and the platelet function results was performed. There were 52 research subjects, each group of single and multiple antiplatelet therapies as many as 26 people, most of the subjects were male (82.6%) with a mean age of 57. The results of this study showed that there was no significant difference in the results of platelet function examinations between single and multiple antiplatelet therapies after 12 months of dual antiplatelet therapy

Abstract

Jatigede Reservoir in Sumedang Regency is a land mass planning designed as a multi-function reservoir. The main water source for this reservoir is from Cimanuk River, which flows through Garut Regency, and has many industrial activities around the river flow. This research was conducted to assess the trophic status of water pollution in Jatigede Reservoir by utilizing plankton as a bioindicator agent. Samples were collected from 9 observation stations from November 2018 until January 2019. The results showed that 26 species of phytoplankton from 7 divisions including Dinophyta, Cyanophyta, Chlorophyta, Chrysophyta, Euglenophyta, Bacillariophyta, and Charophyta was found in Jatigede Reservoir at about 461 ind/m3. Zooplankton abundance of 6 species from 2 divisions of Rotifera and Copepoda at 2 ind/m3. The average phytoplankton diversity index was 0.93 and zooplankton diversity index was 0.23. The average phytoplankton evenness index was 0.44 and zooplankton evenness index was 0.24. The average dominance of phytoplankton was 0.58 and dominance of zooplankton was 0.25. Based on the plankton community structure, the trophic status of Jatigede Reservoir was classified to moderate polluted (eutroph) to heavily pollutants (hypereutroph). The dominant species was Perinidium sp from Dinophyta division.

Abstract

Anthracnose disease is a major disease in cayenne pepper triggered by fungal pathogen Colletotrichum capsici which can cause yield losses of up to 90%. Control of disease generally utilizes synthetic fungicides, but it damages the environment and human health. Hence, alternative controls that are ecofriendly are required. One of the attempts is to make use of chitinolytic bacteria's potential. This study aimed to screen UB Forest chitinolytic bacteria and to determine their potential in suppressing anthracnose in cayenne pepper. Stages of research include a screening of 78 UB Forest bacteria as chitinolytic bacteria, selection of chitinolytic bacteria that are antagonistic against C. capsici, inhibition test of chitinase crude extracts against C. capsici growth, controlling anthracnose disease in cayenne using chitinolytic bacteria, and molecular identification. Based on the results of the selection, there were 76 isolates of UB Forest bacteria classified as chitinolytic bacteria, 74 bacteria antagonistic against C. capsici. Chitinase crude extracts significantly affected C. capsici growth inhibition compared to fungicide treatment. The application of Pseudomonas aeruginosa (UB 11) and Bacillus cereus (UB 12) can control anthracnose disease in cayenne pepper with the intensity of 41.67% and 38.89% respectively with the efficacy level of 58.33% and 61.11%.
