Abstrak – Penelitian ini bertujuan untuk mengkaji pengaruh waktu paparan gelombang ultrasonik terhadap pengurangan jumlah koloni bakteri coliform pada sampel air sungai Kahayan. Pengambilan sampel air sungai dilakukan dengan teknik Grab Sampling menggunakan alat Kemmerer Sampler. Sampel air yang didapatkan diberikan paparan gelombang ultrasonik secara langsung, tanpa merubah kondisi lingkungan awal. Waktu paparan divariasikan pada 1 jam, 2 jam, 3 jam, 4 jam, dan 5 jam dengan frekuensi 40 kHz untuk memperoleh data waktu optimum. Uji coliform dilakukan dengan metode MPN, dengan tahapan uji pendugaan, uji penegasan, dan perhitungan koloni. Hasil uji MPN 24 jam setelah paparan menunjukkan bahwa penggunaan ultrasonik sebagai antibateri dapat optimum ketika diberikan paparan dengan waktu 3 jam, dengan efisiensi  96%. Kata kunci: antibakteri, coliform, ultrasonik, water treatment, sungai Kahayan  Abstract – This study aims to examine the effect of ultrasonic wave exposure time on reducing the number of coliform bacterial colonies in the Kahayan river water samples. River water sampling is done using the Grab Sampling technique using the Kemmerer Sampler tool. The water samples obtained were given direct ultrasonic wave exposure, without changing the initial environmental conditions. The exposure time is varied in 1 hour, 2 hours, 3 hours, 4 hours and 5 hours with a frequency of 40 kHz to obtain optimum time data. Coliform test was carried out by the MPN method, with the stages of the estimation test, affirmation test, and colony calculation. The MPN test results 24 hours after exposure showed that the use of ultrasonic as an antibody can be optimum when given exposure with a time of 3 hours, with an efficiency of 96%.Keywords : antibakterial, coliform, ultrasonic, water treatment, Kahayan river

The general AutoRegressive Integrated Moving Average (ARIMA) model can be written as the sum of noise and exogenous components. If an exogenous impact is trivially small, the noise component can be identified with the conventional modeling strategy. If the impact is nontrivial or unknown, the sample AutoCorrelation Function (ACF) will be distorted in unknown ways. Although this problem can be solved most simply when the outcome of interest time series is long and well-behaved, these time series are unfortunately uncommon. The preferred alternative requires that the structure of the intervention is known, allowing the noise function to be identified from the residualized time series. Although few substantive theories specify the “true” structure of the intervention, most specify the dichotomous onset and duration of an impact. Chapter 5 describes this strategy for building an ARIMA intervention model and demonstrates its application to example interventions with abrupt and permanent, gradually accruing, gradually decaying, and complex impacts.
