Metode: Penelitian ini menggunakan metode penelitian kuantitatif dengan desain studi eksperimen. Jumlah sampel penelitian ini sebanyak 64 sampel air limbah terolah pada outlet di Instalasi Pengolahan Air Limbah Puksesmas X Jakarta. Data kadar total coliform didapatkan dari hasil pemeriksaaan sampel di laboratorium terakreditasi. Sinar ultraviolet menggunakan lampu TL UVC merk Philips dengan daya 15 watt.
Hasil: Berdasarkan rata-rata persentase penurunan kadar Total Coliform pada sampel setelah mendapatkan perlakuan dengan sinar ultarviolet setelah 2 menit sebesar 10%, setelah 4 menit sebesar 21,25%, setelah 6 menit sebesar 26,75%, setelah 8 menit sebesar 42,5%, setelah 10 menit sebesar 58,75%. Persentase penurunan total coliform setelah 10 menit penyinaran memiliki efektifitas yang paling tinggi. Dari uji korelasi diketahui bahwa ada hubungan yang kuat antara lama penyinaran ultraviolet dengan penurunan total Coliform.
Background: This study aims to determine the effective time to reduce total coliform levels by using ultraviolet light in treated wastewater at the outlet of the Wastewater Treatment Plant of Health Center X in Jakarta in 2022.
Methods: This research uses quantitative research methods with an experimental study design. The number of samples in this study were 64 samples of treated wastewater at the outlets of the Wastewater Treatment Plant of Public Health Center X Jakarta. Data on total coliform levels were obtained from the results of examination of samples in an accredited laboratory. Ultraviolet light using Philips brand TL UVC lamp with 15 watts of power.
Results: Based on the average percentage decrease in Total Coliform levels in the sample after receiving treatment with ultraviolet light after 2 minutes by 10%, after 4 minutes by 21.25%, after 6 minutes by 26.75%, after 8 minutes by 42.5 %, after 10 minutes of 58.75%. The percentage of total coliform decrease after 10 minutes of irradiation had the highest effectiveness. From the correlation test, it is known that there is a strong relationship between the duration of ultraviolet irradiation and the decrease in total Coliform.
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
Kualitas air Sungai Ciliwung semakin hari semakin menurun. Hal ini dibuktikan dengan konsentrasi TSS (Total Suspenden Solid), COD (Chemical Oxygen Demand), Nitrit dan Ammonia yang telah melebihi baku mutu (TSS>100 ppm, COD>10 ppm, Nitrit>0.06 ppm, Ammonia>0.02 ppm) (Delinom et al., 2002). Tetapi pada kenyataannya air Sungai Ciliwung masih digunakan masyarakat sekitar untuk memenuhi berbagai keperluan sehari-hari.Penelitian ini bertujuan untuk mengetahui kualitas air Sungai Ciliwung periode tahun 2000-2010 dibandingkan dengan Keputusan Gububernur DKI Jakarta No. 582/1995. Metode yang digunakan dalam penelitian ini adalah metode analisis deskriptif dengan jumlah sampel sekunder sebanyak 272. Parameter kualitas air yang digunakan sebagai indikator adalah Total Dissolved Suspended (TDS), Kekeruhan, Phospat, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) Dissolved Oxygen (DO), dan Fecal coli.Hasil penelitian menunjukan bahwa sebagian besar parameter telah melebihi baku mutu kecuali TDS di bagian hulu sungai. Dari hasil uji bivariat diketahui sebagian besar konsentrasi parameter meningkat dari hulu ke hilir. Hal ini dibuktikan dengan nilai P<0.05. Untuk perbedaan konsentrasi di musim hujan dan musim kemarau, parameter yang memiliki perbedaan yang signifikan yaitu BOD, Phospat, dan COD (P<0.05). Sedangkan untuk perbedaan konsentrasi periode tahun 2000-2005 dan periode tahun 2006-2010 parameter yang memiliki perbedaan yang signifikan yaitu COD dan DO (P<0.05).Kesimpulan dari penelitian ini adalah Air Sungai Ciliwung menurut parameter yang diteliti sudah tidak sesuai peruntukannya.
Over the time, water quality of Ciliwung River was under the standart. The concentration of some parameters such as TSS (Total Suspenden Solid), COD (Chemical Oxygen Demand), Nitrite and Ammonia above a threshold limit (TSS>100 ppm, COD>10 ppm, Nitrite>0.06 ppm, Ammonia>0.02 ppm) (Delinom et al., 2002). But in the reality people around the river area still used the water for their daily activities.The purpose of this study was to compare the water quality to according Keputusan Gububernur DKI Jakarta No. 582/1995. This study use descriptive analysis method with 272 secondary samples. The parameter of water quality which include as indicator of the assessment were Total Dissolved Suspended (TDS), Turbidity, Phospate, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) Dissolved Oxygen (DO), and Fecal coli.The result should that most of parameters were over the threshold limit except TDS consentration in the upstreams. Bivariate analysis showed most of the parameters increase from the upstream to downstream with P<0.05. BOD, Phospat, and COD had the significant differences between rainy and dry season (P<0.05). Mean while COD and DO which had the significant differences in 2000-2005 to 2006-2007 periode time (P<0.05).The conclusion of this study was Ciliwung river water according to the studied parameters are not appropriate designation.
