Abstract

Weather observations can be done in two ways, namely weather observations based on weather stations and based on remote sensing such as satellites. One of these weather study data is rainfall measured from the BMKG rain observation post and TRMM satellite observations. To see the pattern of the distribution of rain that has occurred, the two weather observations can be connected as a reference for the distribution of rain. The purpose of this study was to analyze the correlation value of rainfall data between BMKG and TRMM by looking at the comparison graph and analyzing the comparison of statistical parameters. This research was conducted using daily rainfall data from 1998-2018 at four rain stations in West Java Province and taking descriptive decisions in the form of pictures and graphs in the form of daily, monthly and annual data. Based on the analysis results, the largest correlation value is in the annual cumulative with a value of 0,88-0,94, the smaller the number of days, the smaller the correlation value. The BMKG and TRMM rainfall data have relatively the same pattern, but the maximum data have differences so that it reduces the correlation value. In the Statistical Parameter analysis, it can be stated that the difference in the values ??of the statistical parameters is directly proportional to the daily cumulative, that the difference in the median and mean values ??in the BMKG and TRMM data is greater in the data with a larger cumulative. Meanwhile, for linear regression analysis, it was found that the greatest value was the cumulative 1-year value with a coefficient of determination from 0,78 - 0,89.

Abstract

The large population and the diversity of activities in big cities in Indonesia have resulted in the emergence of common problems in urban infrastructure services, such as solid waste problems. One of them is the city of Bandung which has the highest landfill load, which is 3.55 m3 (BPLHD, 2008). According to data from PD Kebersihan Bandung City, that waste services only cover 62.73% of the total waste generation. Currently, waste in the city of Bandung is disposed of at the Sarimukti TPA, which is located in Cipatat District, West Bandung Regency. This location and the city of Bandung is relatively far, which is about 45 km from the center of Bandung. The results of the evaluation transport trucks from TPS to TPA Sarimukti at 1 ritation obtained a total time of 10 hours, in the waste collection system only exist one driver who works day and night. The potential gas from CO2 and CH4 landfills to cause a greenhouse effect, it is necessary to capture gas. The IPL configuration, TPA sarimukti consists of an Anaerobic Pond, Aerobic Pool, Sedimentation Pond and Sanitation Pool. However, the parameters for COD, BOD, TDS, free ammonia, and H2S have not met the quality standard. The treatment efficiency is low for COD of only 20% due to the design depth that does not meet the design criteria, the number of aerators is insufficient or the aerators are not started according to the requirements so that the oxygen supply in the aerobic pond is reduced.
