Abstract

Natural Sciences (IPA) emphasizes students' science process skills in every learning process. However, looking at the facts in the field when studying science, students still tend to memorize concepts, theories, and principles without understanding the discovery process. This has an impact on the ongoing learning process being uninteresting so that students become bored and ultimately causes students' understanding of science concepts to become low. This research aims to determine the quality of science process skills of class VII students at Kanda Middle School. The research method used is quantitative. The population is all class VII students at Kanda Middle School, totaling 46 people, while the sample in this study was 23 students taken by random sampling. The instruments used are performance that assesses practicum activities as well as interview guidelines used to gather information from science teachers. Data were analyzed using the percentage value formula. This research concludes that the science process skills of class VII Kanda State Middle School students have a percentage of 70.01% in the skilled category.

Abstract

River diversion is a procedure carried out prior to constructing a dam. It is conducted by diverting water from the main river so that the main dam construction work can be executed at a specifically dry area. In Meninting Dam, the diversion system consists of two main structures, namely cofferdam and diversion tunnel that is equipped with a navigation structure at the upstream part of the tunnel. During the construction, cofferdam experienced overtopping on June 17, 2022. The overtopping most likely occurred because of the diversion tunnel’s inability to divert the actual flood effectively during the construction. Therefore, this research aimed to analyse the effectiveness of Meninting Dam’s proposed diversion tunnel against design flood discharge for a return period of 25 years. The data used in this research were the updated version of the ones used to design the whole construction of Meninting Dam’s diversion system, while the flow conditions along the diversion tunnel were analysed using HEC-RAS. At the same time, the analysis was also carried out using the Level Pool Routing Method as a comparison. The analysis results show that the design flood discharge for a return period of 25 years in Meninting Dam Watershed is 265,62 m3/s. This causes the water level along the diversion tunnel reach el. +165,95 m above sea level. Taking into account that the cofferdam crest elevation is at +170,00 m above sea level, it could be concluded that Meninting Dam’s proposed diversion tunnel, which is 4 m wide and 4 m tall is able to divert the design flood discharge for a return period of 25 years effectively. The investigation results in Meninting Dam Watershed show that the main cause of the overtopping was heavy precipitation. This caused the increasing water level at the upstream part of the cofferdam that resulted to its inability to function properly, taking into account that it was still under construction when it occurred
