Acute Respiratory Infection causes symptoms that last for 14 days usually asymptomatic or mild to severe and fatal disease depending on the cause environmental factors and host factors. This study aims to determine the relationship of residential density and ventilation area with the incidence of respiratory infection. This research method is an observational study with cross sectional design. The population in this study were all residents who lived in 24 Ilir Bukit Kecil Palembang namely 196 housing units and a sample of 66 samples and sampling techniques with simple random sampling. The results showed that 69.7% of respondents experienced respiratory Infection. Based on statistical tests it was found that there is a relationship between the area of the room with respiratory infection with p value = 0.003 (p <0.05) there was a relationship between occupancy density and respiratory infection p value = 0.003 (p <0.05) had a relationship and ventilation has no relationship with the incidence of respiratory infection with p value = 1,000 (p> 0.05) so it can be concluded that the area of the room and occupancy density has a relationship with the incidence of respiratory infection.
Waste can cause environment problem in many aspects if it is not handled properly. On the other hand, waste can give safe and comfort feelings if it is well managed. Besides, the right waste management can be a product that has economic and social values. It can be done through social empowerment program. The program is aimed at changing the perspective and knowledge of the people about waste, so that waste can be managed properly and has economic value. Meanwhile, the program target is the people in Sungsang Village, Banyuasin, Sumatera Selatan. The program is carried out in various ways, namely socialization, training, practice, processing accompaniment, and waste management. The result of the empowerment conducted showed that there was a change in the perspective, knowledge, and social behaviour towards waste. The interest of the people to manage waste independently has grown well. They got the feeling of safe and comfort, and the economic benefit with proper and wise waste management, both the inorganic and organic waste. The program is hoped to be sustainable so that waste problems can be minimized disseminated to the people in Sungsang Village,
Latar Belakang : Aerasi merupakan salah satu metode yang dapat digunakan untuk menyisihkan kandungan logam dalam air, baik air tanah, air permukaan, maupun air limbah. Salah satu jenis aerator dalam proses aerasi adalah trayaerator. Sumber air bersih bagi warga Desa Desa Tirtamulia Kecamatan Makarti Jaya Kabupaten Banyuasin berasal dari air sumur gali yang memiliki ciri fisik berwarna kuning kecoklatan. Tujuan: ini untuk mengetahui efektivitas penggunaan variasi jumlah tray aerator dalam menurunkan konsentrasi Fe dan Mangan pada air sumur gali. Metode: penelitianinimenggunakan rancanganpenelitianQuasi Eksperiment,jenis nonequivalent control group designdimana subyek dibagi menjadi 3 perlakuan yaitu 3 tray, 5 tray dan 7 tray dan replikasi masing-masing 3 kali sehingga jumlah sampel sebanyak 30 sampel yaitu 27 perlakuan dan 3 kontrol. Hasil: pengukuran kadar Fe, Mn dan pH pada air sumur gali penduduk Desa Tirtamulia Kecamatan Makarti Jaya Kabupaten Banyuasin didapatkan bahwa kadar pH 7,63µg/liter, kadar Fe 64,810 µg/liter dan kadar Mn yaitu 182,421 µg/liter. Proses Aerasi mampu menurunkan kadar Fe dan Mn pada air sumur gali penduduk Desa Tirtamulia Kecamatan Makarti Jaya Kabupaten Banyuasin sebelum dan sesudah aerasi, namun hasil uji statistik terhadap variasi jumlah tray diperoleh hasil tidak ada perbedaan variasi jumlah tray aerator dalam menurunkan kadar pH, Fe, Mn pada air sumur gali Desa Tirtamulia Kecamatan Makarti Jaya Kabupaten Banyuasin.Saran : Perlu dilakukan penelitian tentang pengolahan air menggunakan aerasi dengan waktu yang berbeda-beda untuk tingkatan tray yang sama dan perlu penggabungan juga dengan proses filtrasi.Keyword : Sumur gali, Tray Aerator, pH, Fe, Mn
Coloring substances in food are generally classified into two categories, namely natural dyes and synthetic dyes. Rhodamine-B is a synthetic dye which is widely used in the textile industry. The use of Rhodamine B in food can cause irritation to digestion, inhalation, and eyes. This research was conducted to detect rhodamine B content in tomato sauce by adding detergent. The design of this study was a qualitative descriptive study conducted on tomato sauce on the market. The test results for the presence of rhodamine-B in tomato sauce with the addition of detergent solution showed that from 6 samples examined, there were 4 samples that had a color change from bright red to pale red. The color change indicates that there is Rhodamine-B in tomato sauce. Positive tomato sauce contains the harmful dye Rhodamine-B using a detergent solution as a medium to determine the content of synthetic dyes qualitatively.
Latar Belakang: Aedes aegypti merupakan nyamuk yang dapat berperan sebagai vektor Demam Berdarah Dengue (DBD). Upaya promotif dan preventif menjadi mutlak dilakukan untuk memutus mata rantai penularan dengan membunuh larva nyamuk dengan larvasida alami menggunakan ekstrak daun sirih (Piper betle) sebagai insektisida alami. Tujuan dari penelitian: ini adalah untuk mengetahui perbedaan abate dan ekstrak daun sirih (Piper betle) dalam mematikan larva Aedes aegypti L instar III. Desain penelitian: ini bersifat eksperimen dengan menggunakan rancangan acak lengkap (RAL) yang terdiri dari 3 perlakuan 1 kontrol dan 8 kali pengulangan percobaan. Hasil Penelitian: dapat diketahui bahwa untuk penggunaan ekstrak daun sirih (Piper betle) dengan konsentrasi 5% dapat mematikan larva sebanyak 8 ekor, sedangkan konsentrasi 10% tidak dapat mematikan larva (0 larva) dan konsentrasi 15% dapat mematikan larva sebanyak 17 (85%) sedangkan untuk penggunaan abate dengan konsentrasi 5%, 10% dan 15% dapat mematikan larva sebanyak 160 larva (100%). Kesimpulan: bahwa abate mempunyai efektifitas lebih tinggi di banding dengan ekstrak daun sirh (Piper betle). Background: Aedes aegypti is a mosquito that can act as a vector of dengue Hemorrhagic Fever (DHF). Promotove and preventive effort are absolutely necessary to break the chain to transmission by killing mosquito larvae with natural larvacides using betel leaf extract (Piper betle) as a natural insecticides. The purposes of this study: this was to determine the differences in abate and betel leaf extract (Piper batle) in kliing Aedes aegypti instar III larvae. Research methods this is an experimental study using a completely randomized design (CRD) consisting of 3 treatments 1 control and 8 repetitions of the experiment. The results: it can be seen that for the use of betel leaf extract(Piper betle) with a concentration cannot kill larvae in 17 (85%) whilke for the use of abate with a concentration of 5%, 10% and 15% can kill larvae of 160 (100%). Conclusion: that the abate has a higher effectiveness compared to sirih leaf extract.
