Setiap tahun penularan penyakit melalui jalur fecal-oral, termasuk diare telahmenyebabkan banyak kematian, khususnya pada anak-anak di dunia.Pemeriksaan kualitas mikroba air dirasa tidak cukup untuk menggambarkansecara akurat tingkat risiko diare. Hal ini dikarenakan faktor sanitasi danperilaku higiene juga berperan penting dalam rantai penularan penyakitdiare. Oleh karena itu perlu dilakukan penelitian mengenai gambaran ataupotret ketersediaan sarana sanitasi dan perilaku hidup bersih sehat (PHBS)pada masyarakat serta hubungannya dengan kejadian diare. Disain studi yangdigunakan adalah potong lintang (cross sectional). Peneliti melakukanpenilaian terhadap kondisi fasilitas sanitasi dan perilaku masyarakat denganmenggunakan data Environmental Health Risk Assessment (EHRA) di 9kelurahan di Kota Depok. Pada setiap kelurahan diambil 60 rumah tanggasebagai sampel sehingga jumlah responden yang digunakan adalah 540rumah tangga. Kuesioner dan lembar observasi digunakan untuk mengetahuikondisi fasilitas sanitasi dan perilaku masyarakat serta kejadian diare.Ditemukan hubungan bermakna antara pengolahan sampah rumah tangga[OR = 0,42 (95% confidence interval (CI), 0,23-0,76)], perilaku cuci tanganpakai sabun [OR = 4,93 (3,11-7,82)], dan perilaku buang air besarsembarangan [OR = 6,61 (2,03-21,58)] dengan kejadian diare. Kesimpulanyang dapat diambil dari penelitian ini adalah kondisi fasilitas sanitasi(pengolahan sampah rumah tangga) dan kebiasaan higiene (cuci tangan pakaisabun dan buang air besar sembarangan) masyarakat memiliki hubungandengan kejadian diare pada masyarakat.Kata Kunci : ciliwung, diare, higiene, kajian risiko, sanitasi

Each year the transmission of disease through fecal-oral route, includingdiarrhea has caused many deaths, especially among children in the world.Examination of the microbial quality of water is not sufficient to accuratelydescribe the level of risk of diarrhea . This is because the factors of sanitationand hygiene behavior also play an important role in the transmission ofdiarrheal diseases. Therefore it is necessary to do research on a picture orportrait of availability of sanitation facilities and hygienic behavior ofhealthy in society and its relationship with the incidence of diarrhea. Weused cross-sectional study design. We conducted an assessment of thecondition of sanitation facilities and people's behavior by usingEnvironmental Health Risk Assessment (EHRA) data in 9 villages in Depok. In each village 60 households taken as a sample so that the number ofrespondents used was 540 households. Questionnaires and observation sheetsare used to determine the condition of sanitation facilities and people'sbehavior and the incidence of diarrhea. We found a significant relationshipbetween household sewage treatment [ OR = 0.42 (95 % confidence interval( CI ) , 0.23-0.76) ] , the behavior of handwashing with soap [ OR = 4.93(3.11 -7.82) ] , and defecation behavior [ OR = 6.61 (2.03 to 21.58) ] with theincidence of diarrhea. From the result we can conclude that the condition ofsanitation facilities ( household waste ) and hygiene habits (washing handswith soap and defecation ) people have a relationship with the incidence ofdiarrhea in the community .Key words : ciliwung, diarrhea, hygiene, risk assessment, sanitation
