Tuberculosis (TB) is a contagious infectious disease caused by the bacterium Mycobacterium Tuberculosis which can attack various organs, especially the lungs. However, before treatment, the diagnosis needs to be made through laboratory tests with the right method with good sensitivity and specificity The purpose of this study was to determine the level of sensitivity and specificity of TB diagnoses. The research method is a descriptive analytic survey research with cross sectional design research design research was conducted from May to October 2019. The place of research was conducted at Pancur Batu Health Center Deli Serdang for taking sputum specimens and blood samples of TB suspect patients. The number of samples in this study were 33 people. The results obtained by the sensitivity and specificity of BTA by 75% and 88.9%. The results obtained sensitivity and specificity of GeneXpert of 95.8% and 100%. The results obtained sensitivity and specificity of Tuberculosis Immunocromatography (ICT) of 28% and 100%. The research results obtained sensitivity and specificity of Interferon Gamma Release Assay (IGRA) of 88% and 100%. BTA is suitable for use, the GeneXpert method is used for the TB RO program and the MGIT Gold Standard for MDR TB.

Malaria is an infectious disease caused by the Plasmodium parasite that lives and reproduces in human red blood cells. This disease is naturally transmitted through the bite of a female Anopheles mosquito. Manifestation of the malaria elimination program using the Artemisinin Combination Therapy (ACT) method, prevention of malaria transmission using LLIN (Long Lasting Insecticidal Net) mosquito nets, and Indoor Residual Spraying (IRS). The purpose of this study was to determine the characteristics of malaria cases based on age, sex, microscopic examination, type of plasmodium and knowledge of respondents. pre test and post test in the IRS program in the working area of Silau Laut Health Center, Asahan Regency. The benefits of this research are expected to provide information about the incidence of malaria with the Indoor Residual Spraying (IRS) program so that it can increase community efforts to prevent malaria in the work area of the Silau Laut Health Center, Asahan Regency. The type and design of this research is Quasi Experiment with Pre and Post Test design without control.. The results of the Pre-Test knowledge of respondents in the medium category were 50 respondents (50%). The results of Post Test knowledge in the medium category increased to 60 respondents (60%). There is an effect of the intervention program on IRS on the knowledge of pre-test and post-test respondents in the work area of the Silau Laut Health Center, Asahan Regency. The Asahan District Health Office needs to conduct operational research on appropriate alternative interventions to increase the coverage of ACT treatment in endemic areas. The Health Office. More intensify all malaria prevention and eradication efforts in the work area of the Silau Laut Health Center in Asahan Regency. Vector eradication with indoor implementation Residual Spraying on a regular basis, Installing wire netting on the ventilation holes of the house. Use of insecticide-treated mosquito nets to prevent mosquito bites at night.

ABCTRACT Tuberculosis is an acute and chronic infections disease that mainly attacks the lungs caused by acid-resistant bacteria (BTA) which are gram positive rods (Mycobacterium tuberculose). Tuberculosis can attack various organs, especially the lungs. This disease if not treated or treatment is incomplete can cause complications until death. The purpose of this study was to determine the description of Acid Resistant Basil in lung TB patients who have been diagnosed by Doctors at Puskesmas Pancurbatu Deli Serdang Regency. This research is descriptive with total population. The sample size in this study was 28 samples. Sputum speech from the study sample was examined by the Zhiel Neelsen staining method. The study was conducted at the Puskesmas Laboratory, Puskesmas Pancur Batu, Deli Serdang Regency. Data were analyzed descriptively. Based on the results of research conducted on Overview of acid-resistant bacilli (BTA) in Patients With Clinical Diagnosis OF Pulmonary Tuberculosis In Pancur Batu Public Health Center Deli Serdang District., apparently 20 samples (71%) were negative and 8 samples (29%) were positive. With the most positive results seen from the age of 17-48 years as many as 5 samples (62%) and those seen from the male Gender as many as 5 samples (62 %). Therefore it is suggested further research is needed by conducting sputum culture in patients with suspected pulmonary tuberculosis but the results of sputum smear examination are negative. Keywords : Tuberculosis, Acid Resistant Bacilli (BTA) ABSTRAK               Tuberkulosis adalah penyakit menular akut maupun kronis yang terutama menyerang paru yang disebabkan oleh bakteri tahan asam (BTA) yang bersifat batang gram positif (Mycobacterium tuberculose). Tuberkulosis dapat menyerang berbagai organ terutama paru-paru. Penyakit ini jika tidak diobati atau pengobatannya tidak tuntas dapat menimbulkan komplikasi hingga kematian. Tujuan penelitian ini adalah untuk mengetahui gambaran Basil Tahan Asam Pada Penderita TB Paru yang telah di Diagnosa Dokter di Puskesmas Pancur Batu Kabupaten Deli Serdang. Penelitian ini merupakan deskriptif dengan total populasi. Besar sampel pada penelitian ini adalah 28 sampel. SpeSimen sputum dari sampel penelitian diperiksa dengan metode Pewarnaan Zhiel Neelsen. Penelitian di lakukan di Laboratorium Puskesmas Puskesmas Pancur Batu Kabupaten Deli Serdang.data hasil penelitian dianalisis secara deskriptif. Berdasrkan hasil penelitian yang telah dilaksanakan tentang Gambaran Basil Tahan Asam (BTA) Pada Penderita Diagnosa Klinis Tuberkulosis Paru Di Puskesmas Pancur Batu Kabupaten Deli Serdang, ternyata 20 sampel (71%) negatif dan 8 sampel (29%) positif. Dengan  hasil positif terbanyak dilihat dari umur 17-48 tahun sebanyak 5 sampel (62%) dan yang dilihat dari Jenis Kelamin laki-laki sebanyak 5 sampel (62%). Denga demikian disarankan Perlu dilakukan penelitian lanjut dengan melakukan kultur sputum pada penderita terduga tuberkulosis paru namun hasil pemeriksaan sputum BTA negatif.

Air payau rasanya agak asin dan tidak segar umumnya keruh, tercemar oleh kotoran (tinja manusia) banyakmengandung bakteri patogen yang dapat menyebabkan penyakit dysentri, kholera, typhoid fever, infectiushepatitis, polio dan lain-lain jika digunakan langsung untuk air minum tanpa terlebih dahulu di masak.Untukmengatasi masalah air payau yang keruh, mengandung bakteri patogen (E.coli) dan kadar garam (salinitas)yang jumlahnya berlebihan, maka dapat dilakukan salah satunya dengan menggunakan saringan pasir danarang aktif. Penelitian ini bersifat eksperimental semu, dengan rancangan yang digunakan ialah Pretest-Postest Control Group design. Tujuan penelitian ini untuk mengetahui pengaruh waktu kontak air payaudalam saringan pasir dan arang kayu terhadap penurunan jumlah bakteri Coli-form , kekeruhan dan salinitasuntuk kebutuhan air minum.Sampel yang digunakan adalah air payau dari Pulau Sicanang Belawan, mediaSaringan pasir dan arang kayu dengan ketinggian 70 cm waktu kontak 1 jam, 2 jam dan 3 jam. Pemeriksaanbakteri Coli-form pada sampel menggunakan pemeriksaan dengan tabung ganda, kekeruhan denganTurbidity meter dan Salinitas menggunakan Refraktometer. Tempat penelitian dilakukan di ruanglaboratorium terpadu Direktorat Poltekkes Kemenkes Medan dengan 3 (tiga) kali pengulangan.Analisa datadilakukan dari tahapan univariat, bivariat. Uji yang dipakai menggunakan t-test dan Anova dengan derajatkepercayaan 95% (α =0,05).Hasil penelitian diperoleh bahwa saringan pasir dan arang kayau dapatmenurunkan MPN Coli-form, kekeruhan dan salinitas dengan waktu kontak 3 jam sebesar 95,8%, 85,6%,85,7%, ada pengaruh waktu kontak 1 jam, 2 jam dan 3 jam air payau dalam saringan pasir dan arang kayuterhadap penurunan jumlah bakteri Coli-form dengan p=0,00 ( p < α =0,05), ada pengaruh waktu kontak airpayau dalam saringan pasir dan arang kayu terhadap penurunan Coli fecal dengan p=0,00 ( p < α =0,05), adapengaruh waktu kontak air payau dalam saringan pasir dan arang kayu terhadap penurunan kekeruhandengan p=0,00 ( p < α =0,05) dan ada pengaruh waktu kontak air payau dalam saringan pasir dan arang kayuterhadap penurunan salinitas dengan p= 0,01 ( p < α =0,05). Petugas Puskesmas dapat mensosialisasikansaringan pasir dan arang aktif dengan ketinggian 70 cm pada masyarakat yang menggunakan air payau untukmemperoleh air minum yang memenuhi syarat kesehatan
