Kecelakaan lalu lintas menjadi salah satu penyebab kematian di dunia. Hal ini masih menjadi masalah global terutama pada negara-negara berkembang. Seiring dengan berkembangnya teknologi saat ini, di Indonesia terdapat aplikasi yang mengenalkan layanan pemesanan ojek menggunakan smartphone. Aplikasi yang paling banyak digunakan adalah aplikasi Go-Jek. Dengan adanya aplikasi Go-Jek berbasis online ini menyebabkan penumpukan kendaraan di jalanan, sehingga faktor resiko kecelakaan semakin tinggi. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang berhubungan dengan perilaku safety riding pengendara Go-Jek di Kota Medan. Penelitian ini merupakan penelitian kuantitatif dengan desain cross sectional. Sampel penelitian adalah pengendara Go-Jek di Kota Medan sebanyak 100 responden yang di ambil secara accidental sampling. Analisis bivariat menggunakan uji statistic Chi Square. Hasil penelitian menunjukkan bahwa faktor yang berhubungan dengan faktor perilaku safety riding adalah usia (p-value = 0,000), masa berkendara (p-value = 0,000), kondisi kendaraan (p-value = 0,000), kelengkapan berkendara (p-value = 0,000). Adapun variable yang tidak berhubungan yaitu pengetahuan (p-value = 0,420), dari hasil yang didapatkan diharapkan adanya peran berbagai pihak, baik pemerintah, kepolisian, institusi pendidikan, serta perusahaan untuk membuat program pelatihan keselamatan berkendara yang aman, serta lebih mensosialisasikan penggunaan perlengkapan sepeda motor. Selain itu, pengendara Go-Jek diharapkan untuk selalu mematuhi tata cara ketentuan berlalu lintas.
<p>Besi (Fe) salah satu unsur penting dalam permukaan air dan air tanah. Senyawa besi dalam jumlah kecil di tubuh manusia sebagai pembentuk sel-sel darah merah,tubuh memerlukan 7-35 mg/hari sebagian diperoleh dari air.Tetapi zat Fe yang melebihi dosis dalam tubuh akan menyebabkan masalah kesehatanseperti merusak dinding usus,berkurangnya fungsiparu-paru,dapat menimbulkan noda pada peralatan dan bahan yang berwarna putih.Tujuan penelitian ini untuk mengetahui penurunan kadar besi(Fe) pada air sumur bor dengan metode aerasi-filtrasi pada air sumur bor masyarakat Jalan Setia Budi, Kel.Tanjung Rejo.Jenis penelitian Quasi Eksperimental Design (Rancangan Eksperimen Semu) dengan desain Pre-Test dan Post-Test.Sampel air sumur bor diambil 1 sumur diKelurahan Tanjung Rejo.Pemeriksaan kadar besi(Fe)dilakukan oleh petugas Lab.Lingkungan.Hasil penelitian secara fisik air yang belum diberikan perlakuan memiliki warna kuning, berbau(karat atau tanah),dan air terasa licin ketika sudah diberikan perlakuan dengan lama kontak 30, 45 dan 60 menit dengan metode aerasi-filtrasi air tersebut jernih dan tidak berbau. Sebelum dilakukan aerasi-filtrasi didapat hasil sebesar 4,25mg/l dan proses penurunan kadar besi dengan Metode Aerasi-Filtrasi dengan lama kontak 30 menit sebesar 3,10 mg/l dan 45 menit sebesar 1,85 mg/l belum memenuhi syarat.Pada waktu kontak 60 menit sebesar 1,00 mg/l dan sudah memenuhi syarat baku mutu sesuai Permenkes No.32 Tahun 2017, kadar maksimum besi sebesar 1,00 mg/l.</p>
Domestic wastewater is used water that cannot be used anymore for its original use, either containing human waste (feces) or from kitchen, bathroom and washing activities. The more dense the population in a settlement the more waste must be controlled. One simple way to treat domestic wastewater is to use anaerobic biofilter based on the type of media. The media used were broken stones, plastic sheets, and coconut shell charcoal. The purpose of this study was to determine the ability of anaerobic biofilter based on the type of media in domestic wastewater treatment. The parameters measured are BOD, COD and PH. Anaerobic biofilter performance is determined by looking at the difference in levels before and after using the media. This research is a quasi-experimental research with one group pretest-posttest design. The sample of this study were 10 samples taken from repetition 3 times in one experiment, the process was done by a batch system. The results showed an average reduction in BOD on plastic sheet media by 84.76%, COD by 84.77%, PH by 32.3%. The average reduction in BOD in the stone medium was 80.57%, COD was 80.59%, PH was 29.66%. The average reduction in BOD in coconut shell charcoal media was 69.72%, COD was 77.84%, PH was24%.
According to WHO data, there were 6.3 million new pulmonary TB cases, this figure is the same as 61% of the incidence of tuberculosis in the world with a value of 10.4 million. The number of patients with TB increased the number of tuberculosis cases from the previous year, which was 9.6 million people. In addition, the number of deaths caused by tuberculosis worldwide is 40 people per 100,000 of the world's population. The aim of the research was to analyze the adherence of drug users in TB patients to the success of therapy at the Medan Deli Health Center in 2022. The population consisted of 112 pulmonary tuberculosis patients who were treated with a total sampling technique with a total of 112 respondents. The results showed that there was a relationship between adherence and successful therapy for TB patients (p = 0.000), there was a relationship between knowledge and successful therapy for TB patients (p = 0.000), there was no relationship between age and successful therapy for TB patients (p = 0.280), there was no gender relationship with successful therapy for TB patients (p= 0.856), there is a relationship between education and successful therapy for TB patients (p= 0.200), there is a relationship between work and successful therapy for TB patients (p= 0.003), there is a relationship between family support and successful therapy for TB patients (p = 0.010) and multivariate analysis that lack of compliance, lack of knowledge and not working has an effect on the failure of therapy.
Covid-19 is an infectious disease caused by a new type of coronavirus with common symptoms of fever, fatigue, cough, convulsions and diarrhea. 8 Covid-19 cases were found and 1 person died in Pasar Gunungtua Village. It is suspected that this is due to the low participation of the community in preventing Covid-19. The purpose of the study was to analyze the factors that influence community participation in preventing Covid-19 in Pasar Gunungtua Village, North Padang Lawas Regency. The type of research is descriptive analytic with a cross sectional approach carried out in March-June 2021. The population is the head of the family who lives in Pasar Gunungtua Village as many as 2,507 families and the sample is 113 people. The results of the bivariate analysis showed that all independent variables had an effect on community participation in the prevention of Covid-19 (p<0.05). Based on the results of multivariate analysis, the dominant variables that influence community participation in preventing Covid-19 are opportunity (OR=5,10), willingness (OR=10,810), ability (OR=6,791), the role of the environmental head (OR=6,613) and the role of cadres/health workers (OR=3.765). It was concluded that people who have a good will tend to participate 10,810 times in preventing COVID-19 disease than those who have a bad will.
Background: The 3M Plus mosquito nest eradication movement is the most effective activity to prevent the occurrence of dengue disease and to realize environmental hygiene and healthy living behavior. The purpose of the 3M Plus mosquito nest eradication activity is to eradicate the breeding places of the Aedes mosquito through efforts to foster community participation so that dengue hemorrhagic fever (DHF) can be optimally prevented.Objective: The purpose of this study was to determine the relationship between the behavior of the head of the family with the implementation of eradicating the mosquito nests of dengue hemorrhagic fever.Method: This type of research uses a descriptive analytic approach with a cross sectional study design with a sampling technique using simple random sampling.
