Abstract

Blotong as one of the wastes produced by sugar industries up to now has not been processed and managed adequately and so that raise people concern. Actually the waste can be utilized as biocharcoal briquette and be used as alternative fuel. Based on this, the purpose of this research is to know whether various shapes (i.e. spherical, cylindric, and cube) of the blotong briquette has diferent water boiling time and smouldering time by conducting an experiment which was following post test only design. The blotong were taken from Madukismo sugar industry in Tirtonirmolo Bantul. The study results showed that the average time for water boiling observed from the cylindric briquette (454,70 seconds) was the fastest compared with the other two; and the average smouldering time recorded from spherical briquette was the longest (i.e. 1805,30 seconds). Both of the results, when analyzed with one way anova test gained p-value lower than 0,05 which can be interpreted that the time differences between the three shapes were significant. Based on the results, the sugar industry as well as the people living nearby are advised to utilize the blotong. Further study to reveal if fresh and old blotong has different briquette quality is needed to carry on.

Abstract

One of the important rooms in a house is bedroom where people can use it for taking a rest or sleeping in a standard of eight hours/day. Based from a preliminary observation held at two bedrooms in Kalitirto Village, the number of microrganisms measured in the ambient air were 3592 colonies/m3and 3204 colonies/m3 respectively. These numbers did not fulfill the maximum number of microrganisms permitted for ambient air in a room i.e 700 colony/m3. Those high numbers of air microorganisms can affect household’s members’ health and furthermore can lead to the emerge of some diseases, such as Tuberculosis and AcuteRespiratory Infection. Because of this case, the study was aimed to decrase the numbers of the air microrganisms by installing glass roofs. The glass roofs were considered as effective media through which ultraviolet in sun rays can enter the rooms, and useful for reducing the number of the existing air microorganisms.The research was a true experimental study which used pre-test and post-test design. The research was conducted in 15 bedrooms, from which three groups of treatment consisted of five bedrooms were set. The sample bedrooms were installed by one, two and three glass roofs respectively. The data was analysed descriptively; and analytically by using paired t-test with sigificancy level at 0,05. The purpose of the research was to understand the influence of glassroofs installation on the number of microorganisms in ambient air of bedrooms, by comparing those numbers between treatment and control groups.Results of the research showed that the p-values generated for the decrease of the microrganisms numbers between the pre-test and post-test were: 0,003 (one glass roofs installation); 0,006 (two glass roofs installation); and 0,002 (three glass roofs installation). Therefore, it can be concluded that the installation of glass roofs on bedrooms affected the decrease of air microorganisms number.

Abstract

The air quality in caring rooms of hospitals is one of important things that have to be considered regarding to the prevention of nosocomial infection. The examination results of air bacterial number in the caring room of PKU Muhammadiyah Hospital of Bantul in 11 February 2013, still exceeded the maximum threshold permitted by the regulation, i.e. 200-500 CFU/m3. One of the alternatives for controlling the condition is by using lime juice concentration as disinfectant, because the fruits contain flavonoid, an anti-inflammatory, anti bacterial, and anti-fungal substance; citric acid, as cleansing agent; and has acidity which suitable for bacterial controlling. The purpose of the study was to determine the influence of five concentration variations of lime juice in decreasing air bacterial number in the caring rooms of the hospital, by conducting a true experiment which employed one group pre-test post-test only design. The sample of air bacteria were obtained before and after the fogging process by using air pump sampler and midget impinger. The results showed that the highest the concentration of lime juice, the highest the bacteria number will be reduced. The average reduction of air bacterial number for lime juice concentrations of 20%, 40%, 60%, 80% and 100% were measured 11,51%; 13,84%; 22,70%; 45,26%;and 55,20%, respectively. One way anova test acquired p-value less than 0,001, which can becloncluded that the difference of the reduction for each concentration were statistically significant. The subsequent LSD test confirmed the evidence that 100% concentration gave the highest results. However, since the yielded bacterial number was still exceeding the permitted limit, it is advised that in its application, the fogging of 100% lime juice concentration should be carried out in five consecutive replications.
