Abstract

This study aims to examine the use of coconut fiber waste as an additive in concrete mixtures for rural road pavements. The construction of road infrastructure and buildings requires materials that are not only strong and durable, but also affordable and environmentally friendly. Coconut fiber was chosen because it is an abundant organic waste, lightweight, and has mechanical properties that can improve concrete performance. The method used in this study is a laboratory experiment with a variation of coconut fiber addition of 5% of the cement weight. The tests carried out include compressive strength tests at the age of 3, 7, 14, 21, and 28 days. The results of the study indicate that the addition of coconut fiber in high amounts tends to reduce the compressive strength of the concrete, not meeting the planned and it can also be seen that there are 3 test objects that are damaged and cannot be tested for compression so that they get a result of 0. and do not support the concept of sustainable development

Abstract

This research aims to re-analyze existing drainage channels in order to find the right solution to overcome the amount of rainwater discharge so that it can match the drainage capacity so that it can overcome one of the causes of farmers' crop failure, especially those who work as corn farmers who are the majority in the area. agriculture in Rodji hamlet, Manawa village. In this research, the data used is secondary data in the form of hydrological data relating to rainfall on a 10 year time scale, starting from 2013 to 2022 and primary data in the form of channel dimensions in the Rodji hamlet area. And in the process of results and discussion, several methods were used that could possibly be studied more widely, and in the analysis results, the method used was the gumbel method which was chosen from four other methods. After carrying out further calculations, the selected result is the channel capacity over a period of 10 years using the Talbot method. The calculation results of the planned rainfall with a 10 year time scale with data on the dimensions of the drainage channels in the research area obtained a control discharge check = 7.738485 m3/second which is smaller than the planned discharge of 11.7743 m3/second so there must be an evaluation of the dimensions of the channel , and after carrying out evaluation research, the results obtained by checking the control discharge showed that the channel discharge = 13.67314 m³/second was greater than the planned discharge = 11.7743 m³/second, it is safe to use and can be a solution to flooding problems in the area.
