Latar Belakang & Tujuan: Klorin digunakan dalam kehidupan sehari-hari sebagai bahan desinfektan, pemutih maupun pembersih. Pencemaran limbah yang mengandung klorin berpotensi mencemari perairan sungai Cidanau. Kadar klor bebas (Cl2) di perairan sungai melebihi baku mutu lingkungan berdampak pada kesehatan masyarakat. Tujuan dari penelitian untuk menganalisis kadar klor bebas (Cl2) dan dampaknya terhadap kesehatan masyarakat di sepanjang Sungai Cidanau Kota Cilegon. Metode: Analisis laboratorium menggunakan alat spektrofotometer pharo-Cl2 untuk menentukan kadar klor bebas (Cl2). Pengambilan sampel air sungai pada 4 (empat) titik sampling yaitu Desa Ranca Senggol Cinangka, Jembatan Cikalumpang, Jembatan Ciparay Cinangka, bendungan KTI Cinangka menggunakan grab sampling. Analisis data dilakukan membandingkan kadar klor bebas (Cl2) dengan baku mutu lingkungan air sungai menurut peraturan PP no. 82 tahun 2001 tentang pengelolaan kualitas air dan pengendalian pencemaran air. Hasil: Hasil penelitian menunjukkan bahwa kadar klor bebas (Cl2) di empat titik sampling yaitu Desa Ranca Senggol Cinangka sebesar (0,335 mg/L), Jembatan Cikalumpang sebesar (0.28 mg/L), Jembatan Ciparay Cinangka sebesar (0,295 mg/L), Bendungan KTI Cinangka sebesar (0,335 mg/L). Kasus penyakit berbasis air di wilayah Kota Cilegon diantaranya penyakit dermatitis (49,4%), gastritis (28,8%) dan kasus diare sebanyak 21,8%. Kesimpulan: Kadar klor bebas (Cl2) di Sungai Cidanau Kota Cilegon melebihi baku mutu lingkungan berdasarkan PP Nomor 82 tahun 2001 yaitu sebesar 0,03 mg/L. Penyakit berbasis air diduga akibat pencemaran klor bebas (Cl2) air sungai Cidanau. Dilakukan pengolahan air limbah di kawasan industri Kota Cilegon.Kata Kunci: Klor Bebas (Cl2), Sungai Cidanau, Penyakit Berbasis Air

ABSTRACT This study aims to determine the effect of education using video animation on an elementary school in handwashing technique. The sample in this study was elementary school students class VI Cigabus Serang, Banten. The instrument used in data collection is a validated test instrument. This study uses a quantitative approach with a quasi experimental single group pretest posttest design.The results of the study showed that the pretest revealed knowledge (26,7%) and excellent hand washing skills (8,3%), and in posttest revealed knowledge (70%) and excellent hand washing skills (73,3%). Handwashing health education using video animation was effective to increase the knowledge and skills of school children regarding the proper technique of handwashing in elementary school (p = 0.000) at a significant level α = 0.05. Education using video animation affects handwashing behavior among elementary school students.   Keywords: Video animation, Elementary school, Handwashing technique.

The Cibanten river is very important for life aquatic organisms and human survival. The purpose of this study was to determine the water quality status and microbiological analyses involved Total Coliform (TC) and estimation of Fecal Coliform (FC) of Cibanten river. Water sampling was conducted along by Cibanten river from up to downstream at six (6) stations for a period from March-October 2017. The number of total and faecal coliform was analysed using the Most Probable Number (MPN) method and STORET method for determining water quality status. Total coliform counts varied from 2400-9200 MPN/100 ml. The maximum total coliform is found in upstream of station 1 (Pabuaran village) 9200 MPN/100 ml was recorded in March-May 2017. Fecal coliform counts varied from 1300-6400 MPN/100 ml. The maximum fecal coliform is found in station 1 (Pabuaran village) 6300 MPN/100 ml was recorded in August-October 2017. Based on STORET method showed that water quality of Cibanten river in moderately polluted. In some situations, even stricter requirements and policies are necessary to achieve sustainability of water quality and ecology in Banten Province.

Perubahan perilaku dan perbaikan kondisi sanitasi lingkungan berperan penting dalam upaya pencegahan dan pengendalian penyakit tuberkulosis paru BTA (+). Tingginya kejadian penyakit tuberkulosis paru BTA (+) di Kota Serang terutama di Kecamatan Taktakan diperlukan upaya-upaya terobosan diantaranya melalui upaya perbaikan dan peningkatan pelayanan klinik sanitasi puskesmas. Desain penelitian ini menggunakan studi cross sectional dengan besaran sampel sebanyak 96 orang penderita tuberkulosis paru (BTA+). Penelitian dilakukan pada bulan Maret-Juli tahun 2019.Teknik pengambilan sampel yang digunakan adalah total sampling. Analisis yang dilakukan adalah regresi logistik. Hasil analisis menunjukkan bahwa pengetahuan (OR= 4,2; 95% CI: 1,529-11,478), dukungan keluarga (OR= 3,9; 95% CI: 1,440-11,004), faktor kebutuhan (need)  (OR= 3,8; 95% CI: 1,258-11,477) memiliki hubungan yang kuat terhadap perilaku pemanfaatan pelayanan klinik sanitasi puskesmas. Pengetahuan, dukungan keluarga dan faktor kebutuhan (need) merupakan faktor dominan berpengaruh terhadap pelayanan klinik sanitasi puskesmas oleh keluarga dengan penyakit tuberkulosis paru (BTA+).

This study aims to determine the factors that cause the behavior of using nutrition services by pregnant women with the risk of KEK at the Nutrition Clinic of the Kasemen Health Center, Serang City. This research method uses cross-sectional research. The results showed that 66.2% of pregnant women at risk of KESK did not take advantage of nutrition services at the nutrition clinic. The behavior of the utilization of nutrition services in pregnant women with the risk of SEZ was most dominantly influenced by support (OR=6.31; 95% CI: 2.633-15.138). In addition, this behavior is influenced by other factors, namely needs (OR = 5.22; 95% CI: 1.608-16.926) and family income (OR = 2.48; 95% CI: 1.061-5.814). In conclusion, pregnant women at risk of CED who do not receive support from their husbands are at risk of 6.31 times more at risk of not using nutrition services than pregnant women with the risk of CED who receive their husband's support.   Keywords: Pregnant Women, Nutrition Services, Risk of Chronic Energy Deficiency (KEK)
