Analisis Laporan Harian Kegiatan Ipal Rusun Damkar Cengkareng dengan Algoritma Decision Tree

Analyzing the activities of an agency or company is important in the running of each agency or company, because by looking at each parameter resulting from each activity analyzed, it can be a consideration for making improvements in the future. Based on the results of the author's interview with employees who work at the wastewater treatment plant of the damkar flat in West Jakarta, the ipal has been established since 2017, then the wastewater treatment technology applied at that place is Membrane Bioreactor (MBR). The author's data collection is based on checking and repair activities carried out by WWTP employees. After obtaining the daily activity report data, the author creates a dataset with attributes from the ipal parts of the damkar cengkareng flat. based on the performance of testing with the decision tree algorithm, the resulting accuracy value is 86,67% with a standard deviation result (+/-) of 23.31%.Based on the results of the analysis of the dataset of daily activity reports that the authors conducted using the decision tree algorithm, that the aerobic biofilter basin is the first or often problematic component of the ipal damkar cengkareng flat. To maximize the wastewater treatment process in the cengkareng damkar flat, it is necessary to add aerobic biofilter tanks to adjust the production of liquid waste from residents
