Abstract

Noise is hearing sensation which pass through the ear and is caused by air pressure deviation. This deviation is usually produced by vibrating or beaten things like guitar strings or drums. High noise level inside music studios can cause some health problems such as fatigue, communication disorder, blood pressure decrease, and some hearing disturbances. The maximum treshold of noise is 85 dB. The study is aimed to understand the relationship between noise intensity and subjective complaint on hearing disturbance among music studio users. This descriptive study used cross sectional survey approach and observed 100 music studio users in Gunungkidul regency. The data was analysed by using chi-square test with 95% degree of confidence, and shows that there are relationship between the variables (p<0,001). It is advised that the musicians should give more attention to use ear protector, such as ear plug for reducing the risk of getting hearing problems.

Abstract

The increase of national corn production impacted to the increase of dry corn husk waste. The waste, if were not handled properly would cause environmental problems. Dry corn husk consist of 15,7 % lignin, 36,81 % cellulose, and 27,01 % lignecellulose, so that it can be used as mate-rial in paper making. The purpose of the study is to understand the influence of dry corn husk pulp variations on the pulling strength of the paper made, by conducted an experimental study which followed post-test only design. Five variations of the mass ratio of used paper pulp and dry corn husk pulp used in this study were: 1:0; 1:2; 1:2.5; 1:3; and 0:1; and were obeserved in nine replications. The results showed that the average of pulling strength of the paper yielded from above five ratio, respectively were: 2.030,02 grams; 7.004,06 gr; 9.038,37 gr; 11.888,78 gr; and 17.970,59 gr. Based on the results of the one way anova test, it was revealed that corn husk waste pulp determined the pulling strengh of the paper produced. The pulp waste only without used paper pulp addition earned the biggest pulling strength. The cellulose, lignin and hemicellu-lose content in dry corn husk were considered have function as an adhesive between the fibers and reinforce the bond and the length of the fibers. To conclude, the bigger the mass ratio be-tween corn husk pulp and used paper pulp, the higher the pulling strength will be gained.

Abstract

Some people in Sidomulyo Village of Kecamatan Pengasih work to make handicrafts made ofapus bamboo. Parts of bamboos which are not used have not yet been utilized and just become waste. The bamboo leaves which are containing 46,24 % cellulose can be utilized as additional material for recycling paper making. The aim of study was to know whether the recycledpapers produced from three mixture formulas of used HVS paper and apus bambo leaves havedifferent tensile strength, by conducting an experiment with post test only control group design.From five replications, it was known that the average paper tensile strength yielded from formula I (400 ml used HVS paper and 600 ml bamboo leaves) was 0,160 N/mm; from formula II (200ml used HVS paper and 800 ml bamboo leaves) was 0,320 N/mm; from formula III (1000 mlbamboo leaves) was 0,386 N/mm; and from control (1000 ml used HVS paper) was 0,106 N/mm. The statistical analysis results from independent t-test and Kruskal-Wallis test at 95 %confidence level showed that those differences were significant, except between the controland the papers produced from formula I, and between formula II and formula III. It can be concluded that the more the apus bamboo were added the more the tensile strength will be obtained. Nonetheless, the best paper tensile strength in this study still lower than that of factorymade carton paper i.e. 6,920 N/mm.

Abstract

One of the organic waste generated from markets is pineapple waste. Parts of pineapple thatcan be eaten is only 53 % while the remaining 47 % were dumped as waste. The peels of pineapple contain 13,65 % sugar, so that can be processed as bioethanol, i.e. ethanol made frombiomass containing cellulose or starch component. The preliminary trial found that the fermentation of pineapple waste in four days with four weight variations of Saccharomyces cereviceaeobtained the highest level of bioethanol at 27,7289 %, i.e. produced from 15 gram of that yeastThe purpose of this research was to know the influence of Saccharomyces cereviceae weightvariation (0 %, 20 %, 40 % and 60 %) and fermentation time variation (4 days, 7 days and 10days) toward the levels of bioethanol produced from pineapple waste of Beringharjo Market, byconducting a post-test only with control group designed experiment. The results show that thehighest levels of bioethanol produced was 40,45354 %, i.e. from the use of 60 % weight of Saccharomyces cereviceae and 10 days fermentation. However, the statistical analysis with two-wayanova test at 95 % level of confidence yielded a probability value >0,05 which means that thelevels of bioethanol produced from those yeast weight variation and fermentation time variationare not significantly different.

Abstract

Flies are vectors of some diseases such as dysentery, cholera, typhoid, diarrhea and worm in-fection. Various techniques of fly control can be applied, one of which is by using chemical sub-stances as repellent. Cananga (Canangium odoratum Baill) has the ability to repel flies be-cause contains phenolic compound, i.e. linalool, eugenol and geraniol, which basically can ex-pel insects. The purpose of this research was to determine the influence of various concentra-tion of cananga oil towards houseflies (Musca domestica) by measuring the power and duration of the obtained repellent. This research was an experiment with post-test only with control group design. The research objects, i.e. 625 houseflies, were used for five expeiment groups which consisted of three treatment groups and two control groups in five repetitions. One way anova test at ? 0.05 revealed that the repellent powers showed from the 20 %, 30 % and 40 % cananga concentration, and the positive control (camphor) and the negative control (castor oil) were significantly different. Therefore, it can be concluded that cananga oil concentration do in-fluence the repellent power. However, the effect on the duration was not significant. To con-clude, 40 % concentration (40 ml cananga oil in 60 ml castor oil) is the most effective for repel-ling houseflies. It has 34.4 % repellent power and 8,4 hours duration.

Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by dengue viruses which is transmittedthrough Aedes aegypti mosquito bite. DHF is mainly found in tropic areas and often leads tooutbreak. One way to prevent this disease is using repellent. One of the ingredients that can beused as a natural repellent is the extract of kenikir (Cosmos caudatus). For ease use as repellent, the extract can be applied in soap bars. The objective of the study was to know the influence of soap bar with kenikir extract formulation on the repelling power for Aedes aegypti mosquitoes, and to know the most effective formulation, by conducting an experiment with pre-testpost-test with contol group design. The extract formulation used in this research was 9 ml, 11 ml,and 13 ml. The data were analyzed statistically by using one-way Anova and LSD (least signifycant different) tests, and the results show that the mosquito repelling powers obtained from various soap bar with extract kenikir formulation were significantly different (p-value = 0,008). Kenikir extracted soap bars which is meet the mosquito repellent standard were the first and thirdreplication of 13 formulation (i.e.100 % and 94 %, respectively) and the third replication of 100 mlformulation (100 %). To conclude, the most effective kenikir concentration is 13 ml.
