<p>One of the community services in the field of food, is hawker food whose existence is often still far from meeting health requirements so that the impact of the disease on the community. By seeing the potential of such large food and high levels of vulnerability, efforts should be made to monitor the quality of food management by observing hygiene and sanitation rules and health requirements. The purpose of this study was to determine the relationship between sanitation hygiene and behavior of the handlers with the number of germs on snacks in the surroundings of the Kartika Jaya Foundation School in Bandar Lampung City. This type of research is analytic descriptive, with the cross-sectional approach. The population in this study is all traders and food sold in the environment around the school both inside and outside the school building. Samples were taken based on the determination of the sample criteria of traders and food, totaling 53 traders. The method used is a laboratory test on the number of germs on food samples and hand-held swabs by the ALT (Total Plate Number) method as well as questionnaires and observations. Data analysis was performed univariately and bivariate (using the chi-square test α=0,05). From the results of this study it can be concluded that there is a relationship between sanitation hygiene (ρ-value=0,0001) and food handler behavior (ρ-value=0,004) with the number of germs on snacks in the surroundings of the Kartika Jaya Foundation School in Bandar Lampung City.</p>
<p><span>Dengue Bedarah Fever (DHF) one of the problem of the disease in Indonesia and including 30 countries in the world endemic for dengue disease, even though be second place disease in 2015 with a Case Fatality Rate (CFR) of 0.95%. Besides in Lampung in the last three years (2014-2016) tendency for Incidence Rate (IR) is increasing. In South Lampung Regency as the gateway to Sumatra Island in 2017 the Incidence Rate (IR) averaged 20.78% and one of the highest Incidence Rate (IR) reached 70.59% in the Hajimena Health Center Working Area, Natar District. The purpose of this study was to find out the relationship between the factors of the Social Environment, Physical Environment, and the Factors of Controlling the DHF Control Program, and factors were the most dominant relationships. The research method is quantitative with the Cross-Sectional approach, with the study population in the Hajimena Community Health Center Working Area, Natar District, which includes three villages namely Hajimena village, Sidosari village, and the Pemanggilan village. Primary data is taken using questionnaires and checklists, and secondary data is sourced from Puskesmas and Kecamatan. Processing data using data processing software by analyzing using univariate, and bivariate methods. The results of this study show that there is a meaningful relationship are the mobility of the population with the incidence of disease. To eradicate dengue in the Natar sub-district, especially the Hajimena Public Health Center area which is an endemic area, it also requires comprehensive and integrated activities, namely PSN-DBD with periodic larvae checks by cadres of the Larvas Monitoring.</span></p>
Groundwater Processing Equipment into Clean Water with a CombinationProcess of Aeration-Upflow Filtration (a Design). In areas that have not received clean water services, residents usually use well water, river water which sometimes even often the water used does not meet the standards of healthy clean water. To treat well water/ ground water is usually the community. build a processing unit in the form of a sand filter. The problem that is often encountered in treatment is cleaning the filter media. This condition is often difficult for the community to do because it requires time and energy, resulting in the sand filter that is supposed to be operational continuously and finally stops and is not even used at all. To overcome this problem, it can be done by improving the design of water treatment units with a system of combination of aeration and upflow flow filtration. This study is to determine the ability of the tool to improve the quality of shallow groundwater in terms of turbidity, Fe, Mn, color and odor to clean water and saturation point of filtering. Research Design is a "quasi-experiment" in the form of "Time Series Design" using a "pre and post test" design without control. The tool is designed in the form of an application prototype to determine its ability to reduce turbidity, Fe, Mn, color and odor and the length of saturation point. The results showed that iron content before processing 2.12 after processing 2,058. pre-treatment manganese content 0.080 after processing 0.078. Color and smell before color processing and odor after processing are colorless and odorless. Microbiological quality for stool coly before processing week 1 32 after treatment 0, week 2 coly of feces before processing 26 after processing 0 and weeks 3 coly of feces before processing 21 and after processing 0. Length of processing up to saturation point filter media total contact time processing is 30 minutes. Bangun). Untuk mengolah air sumur/air tanah biasanya masyarakat membangun unit pengolahan berupa saringan pasir. Masalah yang sering ditemui dalam perawatan adalah pembersihan media saring. Kondisi ini sering sulit dilakukan oleh masyarakat karena membutuhkan waktu dan tenaga sehingga mengakibatkan saringan pasir yang seharusnya beroperasional secara terus menerus akhirnya terhenti dan bahkan tidak digunakan lagi. Untuk menanggulangi masalah tersebut, dapat dilakukan dengan cara memperbaiki rancang bangun unit pengolahan air dengan sistem kombinasi aerasi dan filtrasi aliran ke atas (upflow). Tujuan penelitian mengetahui kemampuan alat dalam memperbaiki kualitas air tanah dangkal dari segi kekeruhan, Fe, Mn, warna dan bau menjadi air bersih serta titik jenuh penyaringan. Desain penelitian"eksperimen semu" berupa "Time Series Design" menggunakan rancangan "pre and post-test" tanpa kontrol. Alat dirancang berupa prototype secara aplikatif guna mengetahui kemampuannya dalam menurunkan kekeruhan, kadar Fe, Mn, warna dan bau serta lamanya titik jenuh. Hasil penelitian menunjukkan bahwa kadar zat besi besi sebelum pengolahan...
<p>Function disorders were generally occurred due to individual factors and environmental factors. One of the industries that experienced a lot of development was PT. Semen Batu Raja which is located in Kelurahan Way Lunik. Dust particles with a size of fewer than 50 microns that normally fly can enter the workers' respiratory tract by being sucked in during breathing (ILO, 1998). Public Health Center of Way Lunik mentioned that the prevalence of ARI that occurred during 2016 amounted to 243 cases. The purpose of this study was to determine the relationship of cement dust levels to vital lung capacity in the community around PT. Semen Batu Raja in 2017. The research method was cross-sectional design. Independent variable was humidity of the house, room temperature, ventilation, smoking habits, gender, age, length of stay, and knowledge. While the dependent variable was lung vital capacity. Based on the results of the study, of the 145 Panjang community respondents around PT. Semen Batu Raja obtained 82 respondents who were diagnosed with pulmonary function disorders. Factors that have a significant influence to pulmonary function disorders were ambient dust levels with mean value 171.5 µg / Nm3 (0.025), home ventilation with mean value ≥ 10% (0.041) and smoking history of respondents with the greatest risk was active smokers. Other factors that were not statistically related were house humidity (0.041) mean 63.2%, house temperature (0.654) mean 29.5⁰C, gender, length of stay (0.82), and knowledge (0.654) This study is expected to be reference studies and studies for several parties.</p>
Sumber pencemaran udara yang utama berasal dari transportasi, dimana hampir 60% dari polutan yang dihasilkan terdiri dari karbon monoksida dan 15% terdiri dari hidrokarbon. Udara dengan polutan yang tinggi berbahaya bagi pekerja operator di SPBU. Tujuan penelitian ini mengetahui pengaruh lamanya bekerja, lamanya kontak langsung operator, dan penggunaan APD petugas operator di SPBU terhadap kandungan oksigen dalam darah. Jenis penelitian ini observasional analitik, dengan desain cross sectional. Pengambilan sampel dilakukan pada 31 SPBU yang ada di Kota Bandar Lampung, pada petugas operator SPBU. Hasil penelitian didapatkan 62 responden, dimana 62,9% responden memiliki kadar oksigen normal. Berdasarkan lama nya bekerja didapatkan 51,6% responden <5 tahun, 33,9% responden 5-10 tahun dan 14,5% responden >10 tahun. Berdasarkan waktu kerja perhari didapatkan 83,9% responden selama 8 jam, 1% responden selama 6 jam. Responden yang menggunakan APD sebanyak 38,7%, dan 61,3% responden yang tidak menggunakan APD. Didapatkan hubungan yang signifikan antara lamanya bekerja dan penggunaan APD dengan kadar oksigen darah responden (p value <0,05), tetapi tidak terdapat hubungan antara lama kerja perhari terhadap kadar oksigen (p value >0,005). Saran bagi pekerja operator SPBU agar menggunakan alat pelindug diri selama berada di area SPBU.
