Abstract

Petroleum waste (crude oil) has become one of the sources of pollution in the sea. The pollution caused comes from several factors, oil spills from tankers, deliberate disposal of irresponsible industries. The layer of crude oil on the surface of the air holds back gas exchange from the atmosphere and reduces the solubility of oxygen in the waters so that it interferes with the respiration and photosynthesis processes in phytoplankton which are food producers in the sea. This study aims to characterize the synthesized TiO2 photocatalyst material using two methods, namely Sol-Gel (SG) and Hydrothermal (HD) which will then be used for applications in petroleum waste. To determine effectiveness of TiO2 photocatalyst in reducing crude oil spills on the sea surface based on fatty oil parameter tests. The synthesis of TiO2 was carried out by the solgel method (SG) and the hydrothermal method (HD) at various temperatures of 300 oC, 500 oC, and 700 oC. Characterization of the material formed using the SEM-EDX instrument, showed that in general it is spherical in shape, and is composed of C, O and Ti elements. The maximum effectiveness of SG-300, SG-500, and SG-700 was able to reduce fat oil content by 57.19%, 66.14% and 41.42% while HD-300, HD-500, and HD-700 were able to reduce fatty oil content. maximum of 60.87%. , 56.41% and 45.68% in the 120 minute irradiation time. The results showed that the photodegradation process in petroleum waste treatment using TiO2 material was able to reduce the fat oil content.

Abstract

The disposable use of medical masks causes a buildup of medical waste masks that can pollute the environment. One of alternative method used to decant a medical mask is the use of the insect Tenebrio molitor. However, the larvae ability to reduce the rate of the masks is not optimal, so it is necessary to combine the diet with organic waste. The purpose of this study is to identify the potential of the larvae T. molitor and so it need to know the weight of the larvae bodies by giving advanced surgical medical masks combined with the organic waste of pineapple peel, papaya peel, dregs of tofu, and palm meal. The method used is a Completely Random Design (CRD) with 4 treatment and 3 repetition. Research indicates that the larvae T. molitor were able to descale the surgical masks of organic waste. The rate of biodegradation of surgical medical masks is estimated at 1,75 gr/days, surgical medical mask + papaya peel 1,73 gr/days, surgical medical mask + pineapple peel 1,72 gr/days and surgical medical mask + palm covers 1,25 gr/days. Correlation analysis obtained r = 0,7413 meaning indicates a strong correlation between died of the combination of surgical medical masks and organic waste on increase the larvae body weight.

Abstract

Low birth weight babies (LBW) are more often problematic because of difficulty maintaining body temperature due to a lack of subcutaneous fat, a large skin surface area to body weight ratio, and reduced heat production due to insufficient brown fat. One of the treatments for LBW is the Kanggoro Mother Care (KMC) method, in which the baby gets warmth and is closer to the mother. The purpose of this study was to determine the effectiveness of implementation (KMC) on changes in body temperature and body weight of LBW. This type of research is quasy experiment. The experimental group in this study there was 1 group that was given an intervention of KMC management, where the body temperature and weight of the baby would be measured before and after the intervention. The data analysis method used is the Wilcoxon test. The results of the statistical test showed that before and after the implementation of KMC, the p value for temperature changes was 0.001 and the p value for weight gain in LBW was 0.022. The conclusion of this study is that KMC is effective against changes in temperature and weight of LBW infants.

Abstract

Escherichia coli is a normal flora found in the large intestine of humans and is opportunistic. Acute diarrhea is the discharge of watery or loose stools in larger amounts than normal, lasting less than 14 days. Acute diarrhea is caused by several microbes, one of which is Escherichia coli. Treatment of acute diarrhea caused by bacteria can be given antibiotics, but the relatively high use of antibiotics can lead to resistance. One of the natural ingredients known to treat acute diarrhea is papaya seeds (Carica papaya L.). Papaya seeds are known to have antibacterial activity because they contain flavonoids (quercetin), alkaloids, saponins, and tannins. This study aims to determine and analyze the antibacterial activity of the ethanol extract of papaya seeds on the growth of Escherichia coli. This research is an experimental study with a post-test only with a control group research design using papaya seeds (Carica papaya L.). The test bacteria used in this study were Escherichia coli with the dilution method to determine the Minimum Inhibitory Concentration (MIC) and the spread plate to determine the Minimum Bactericidal Concentration (MBC). The results showed that MIC was present at a concentration of 2%, while MBC was at a concentration of 5%. It was concluded that the ethanol extract of papaya seeds (Carica papaya L.) had antibacterial activity against Escherichia coli.
