Identification of species of flies can see the characteristics of the body shape of flies by looking at organs identified by using a microscope and identification key book of adult fly species using Borror identification keys, and literature search by examining books and articles about flies, guidelines for entomological surveys. The body of flies is usually short, small and slender life flies are very adaptable to the surrounding air. Knowing the fly's morphology and measuring the density of flies by identifying the species of flies in this study is one of the efforts to determine the level of density and population distribution of fly species in the Berastagi market. The fly is one of the insects of the Order listed which is a member of the Hexapoda class or the insect has the largest number of genera and species which covers 60-70% of all Anthropod species or 60,000 - 100,000 species of flies.
Biolarvasida sederhana yang terbuat dari serbuk daun sirih dapat diaplikasikan kedalam penampungan air bersih dan mampu mengurangi jentik nyamuk aedes aegepty. Pembuatan biolarvasida ini secara sederhana disampaikan kepada masyarakat Desa Sibolangit Kecamatan Merek Kabupaten Karo Sumatera Utara melalui kegiatan Pengabdian Masyarakat. Sasaran kegiatan pengabdian ini adalah perangkat desa dan ibu PKK 25 orang dan masyarakat sebanyak 150 orang. Metode kegiatan menggunakan metode ceramah dan demonstrasi. Langkah-langkah kegiatan adalah ceramah untuk menjelaskan kajian tentang penyakit demam berdarah dengue (DBD) dilanjutkan tanya jawab, demonstrasi pembuatan biolarvasida dari daun sirih. Faktor pendukung kegiatan pengabdian dari Kepala desa dan perangkat desa Kader/ibu PKK, dan antusiasme peserta pengabdian, sedangkan faktor penghambat kegiatan adalah keterbatasan waktu pelaksanaan pengabdian. Kegiatan pengabdian secara keseluruhan dapat dikatakan baik dan berhasil, dilihat dari keberhasilan target jumlah peserta pelatihan (100%), ketercapaian tujuan pelatihan (92%), ketercapaian target materi yang telah direncanakan (80%), dan kemampuan peserta dalam penguasaan materi (92%). Kegiatan pengabdian dapat meningkatkan pengetahuan ibu PKK dasar tentang daur hidup nyamuk aedes aegepty, pola penyebaran penyakit demam berdarah dan pentingnya menjaga kesehatan dan kebersihan lingkungan tempat tinggal dan keterampilan peserta dalam pembuatan biolarvasida dikatakan berhasil bila 80% mereka sudah terampil dalam pembuatan biolarvasida dengan benar sedangkan hasil yang didapatkan adalah 88%.
BACKGROUND: Tuberculosis is an infectious disease and global concern today. AIM: This study aims to map the incidence of pulmonary tuberculosis risk factors in Kabanjahe District, Karo Regency. METHOD: This research is an ecological study with a case-control study design. This research was conducted in Kabanjahe District in January - October 2020. All people who checked and declared to have tuberculosis based on clinical symptoms to be the population in this study. The sample size was calculated with a minimum sample size of 58 for the case group and 58 for the control group with a ratio of 1:1. The distribution pattern of pulmonary tuberculosis and environmental risk factors with the incidence of tuberculosis was carried out using a Geographic Information System (GIS) to determine the distribution of cases. Spatial analysis used average nearest neighbor, overlay and buffer followed with logistic regression as multivariate statistical analysis. RESULT: The distribution pattern of pulmonary tuberculosis in Kabanjahe District tends to group (clusters). GeoDa software found the relationship between population density and tuberculosis incidence in Kabanjahe District with p values 0.04. There is a relationship between income, ventilation, floor conditions, humidity, and lighting with the incidence of tuberculosis. Humidity is the most dominant variable associated with the incidence of tuberculosis. CONCLUSION: The incidence of tuberculosis cases in Kabanjahe District is dominantly influenced by the humidity factor of the house which is increasingly at risk due to poor ventilation, unstable room temperature, and bad circulation.
Kecelakaan kerja merupakan permasalahan yang sering terjadi pada pekerja baik pada sektor informal maupun sektor formal termasuk pada pekerja las. Tujuan penelitian ini adalah untuk menganalisis faktor kecelakaan kerja dilihat dari umur, tingkat pendidikan, masa kerja, pengetahuan, sikap kerja, penggunaan APD, lingkungan kerja. Jenis penelitian analitik dengan desain cross sectional. Pengumpulan data menggunakan kuesioner dengan sampel 55 pekerja yang merupakan total populasi. Lokasi penelitian yaitu bengkel las listrik yang berada di Desa Bandar Klippa Kecamatan Percut Sei Tuan. Analisis data secara univariat dan bivariat dengan menggunakan uji Chi Square. Hasil penelitian menunjukkan 54,5% pekerja mengalami kecelakaan kerja pada saat pengelasan. Berdasarkan hasil analisis bivariat di dapatkan bahwa semua variabel berhubungan dengan kecelakaan kerja yaitu umur (p value = 0,.020), pendidikan (p value = 0,015), masa kerja (p value = 0,029), pengetahuan (p value = 0,001), sikap kerja (p value = 0,024), penggunaan APD (p value = 0,004) dan lingkungan kerja (p value = 0,046). Pemilik industri bengkel las sebaiknya mengadakan pelatihan tentang upaya pencegahan kecelakaan kerja dan membatasi waktu kerja tidak lebih dari 40 jam dalam 1 minggu, agar mengurangi risiko kecelakaan kerja.
Tuberculosis (TB) is a direct infectious disease caused by TB (mycobactic tuberculosis) germs. The disease is still in the attention of the world and until now, there are no one neither country free from TB. Deli Serdang regency is an regency with the highest Tuberculosis case discovery in North Sumatra Province. This study was observational research with the design of study control cases, in order to determine the characteristics of the patient and the risk factor for the tuberculosis incident. The number of samples is 45 cases and 45 controls. The characteristic association and risk factors with the incidence of tuberculosis were analyzed in univariat and bivariat, Analysis is carried out using cross-con 2x2 to calculate the value of prevalen ratios and confidence values (CI). Statistical test used for analysis is chi square at the trust rate 95% (? = 5%). The results of the lighting study are obtained from the value of OR 0.348, CI 0.144 - 0.840 and p-value 0,031. Residence density obtained from the OR 0.35 CI 0.142 - 0.700 p-value 0.020 and Venting obtained from the OR 0,348 CI 0,144 – 0,840 p-value 0.031. Lighting, venting, and residence density have a relation with the incident TB in Kabanjahe District, while the variables with no relation are temperature, moisture and house floor condition.
