Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by virus and transmitted by Aedes sp. mosquitoes. Most areas in Indonesia is endemic where frequency of outbreaks is escalating and the disease is one of major health problems in Indonesia. One way to avoid mosquito bites is by using repellent. However, repellent with active ingredients made from synthetic chemicals have side effects that harmful for human health. Therefore, it is a necessity to seek safer natural ingredients, one of which is kamboja flowers (Plumeria alba). The purpose of this study is to determine the effect of extract concentration variation of that flower in the lotion as a repellent and to find the most effective one. The research method used was an experiment with post test onlywith control group design. Kamboja flower extract concentration added into the lotion were 20 %,30 %, and 40 %. The results were analyzed by statistical tests using two way anova and LSD at 95 % level of confidence. The results showed that the extract concentration variation significantly gave different repellence power (p=0,039) to Aedes sp. and 40 % was found as the most effective concentration. The repellence power of this concentration at the first and the fifth hour of observation were 83,81 % and 3,52 %, respectively.

Abstract

One of environmental issues that still a problem is waste. One of the waste sources is rempeyek industry in Pelem Madu, Imogiri, Bantul, Yogyakarta Province that produces solid waste in the form of peanut shells and has not yet been processed adequately. Peanut shells contain of 63,5 % cellulose which can be used as additional component in paper recycling process. The purpose of this research was to know the effect of five composition ratio of peanut shells towards the tensile strength and water absorption of the recycled papers, by conducting an experiment which followed post test only with control group design. From the measurement of paper tensile strength, the averages from five times replication for each composition ratio between used papers and peanut shells (i.e. ,1:0,5; 1:1,0; 1:1,5; 1:2,0; and 1:25) were: 0,519 N/mm; 0,751 N/mm; 0,777 N/mm; 0,905 N/mm and 1,118 N/mm, consecutively. Meanwhile, the obtained means from water absorption test for the same composition ratios, were: 71,4 mm; 72,2 mm; 72,8 mm; 65,2 mm and 57,2 mm, respectively. The One Way Anova test at 0,05 level of significance, yielded a p value < 0,001 which means that the composition ratio variation significantly influenced the tensile strength and the water absorption of the yielded papers. The best composition ratio for both parameters is 1:2,5 and it can be concluded that the more peanut shells were added to the process, the produced paper will gain the higher tensile strength and the more able to reduce water absorption.

Abstract

Sanitation is an attempt to oversee some physical environmental factors that affect humans, especially for things that have deleterious effects, to physical development, health, and life survival.Based on the preliminary test conducted on 2 to 4 April 2016, it was revealed that there weresome facilities that did not comply with the requirements. This condition has bad impact on theenvironment and human health. The purpose of this study was to describe the sanitation condition of bus stations in Yogyakarta Province by conducting survey study with descriptive analysis.From the population of 16 bus-stations located in the province, as the sample were Wates BusStation, Jombor Bus-Station, Giwangan Bus-Station and Dhaksinarga Bus station which wereselected by using are probability sampling method. There were five variables under study whichwere observed by doing sanitation inspection, i.e. outdoor environment, indoor and building, sanitation facilities, comfort and safety, and food and drink hygiene. Based on the study results, itcan be concluded that sanitation condition in bus-stations in Yogyakarta is still not good, sinceonly Giwangan Bus-Station that can be categorised as properly healhty, with 89 % compliance.
