Abstract

The design rainfall value is a critical parameter in flood analysis and water structure design. In general, the design rainfall calculation uses measured rainfall data. However, sometimes it is difficult to find complete rainfall data from evenly distributed rainfall stations and in an extended measurement range. This study aims to test the use of CHIRPS satellite-based rainfall data as an alternative solution for providing data in areas with difficulty with rainfall data. The analysis includes data accuracy and calibration evaluation, followed by design rainfall analysis with frequency analysis and mapping using spatial data processing software. The accuracy test results obtained an average deviation value of the original CHIRPS that did not meet the average NSE value of 0.346. Furthermore, the data was calibrated using the regression method, and corrected data was obtained with an NSE of 0.446 with an interpretation of the meeting. A rainfall analysis was conducted for corrected CHIRPS with ARR (Automatic Rainfall Recorder) measurement as a control. The results obtained the average percentage deviation for design rainfall with a return period of 2, 5, 10, 25, 50, and 100 years using corrected CHIRPS ranging from 18 - 28% lower than design rainfall using ARR. The design rainfall isohyet map using spatial data processing software for the North Lombok Region shows that high design rainfall occurs in the eastern part of North Lombok, namely around the Santong and Sambik Bangkol stations, while design rainfall with low values is in the western part of North Lombok, namely around the Tanjung and Gunungsari stations.

Abstract

The Jelantik Village community still faces environmental problems, especially the problem of waste generation that disrupts environmental comfort. The limited capacity of the village government and the low level of community knowledge in processing waste are the main causes of this problem. So, this community service activity aims to disseminate information about processing organic waste into eco enzyme, which is beneficial and simple in procedures. Socialization is carried out using a counseling method on how to make eco enzyme using fruit/vegetable waste mixed with sugar and water in a ratio of 3:1:10. This counseling has eco enzyme carried out and attended by at least 30 participants. The team has delivered counseling on how to select materials, the process of making eco enzyme, and how to utilize it. The team informed the Jelantik Village community about the principles and stages of making eco enzyme correctly so the community can practice it to process their waste at home. This activity is expected to increase community knowledge while reducing waste problems, producing beneficial eco enzyme, and promoting SDGs-12 achievement.
