Abstract

The hydraulic system is an energy transmission system utilizing liquid fluids. Liquids possess a characteristic different from solids in their inability to withstand shear stress. The employed methodology is qualitative research, also referred to as naturalistic qualitative research, which entails a natural implementation without manipulating circumstances. This study aims to identify the causes of damage to the hydraulic system in the press section machine, along with implementing appropriate corrective measures, while examining the hydraulic functioning of the press section machine. The research problem specifically focuses on analyzing the damage to the hydraulic cylinder and addressing cylinder seal failure. The damage results from seal wrinkling caused by aging, heat and wear. It is important to ensure that the hydrostatic test pressure is carried out at pressures up to 20 MPa with a holding time of at least 30 seconds. This examination ensures that the hydraulic roll press problem has been fully resolved and will not reoccur. Hydraulic systems offer numerous advantages as an energy source in various applications. These advantages include their lightweight nature, ease of installation, and low maintenance requirements. Inadequate performance in the hydraulic roller pressure section is attributed to a hydraulic cylinder seal that does not meet the specified standards, necessitating replacement with a suitable seal.

Abstract

Micro hydro power plants are small power plants that use water as energy, and the initiative is a turbine. This generator system is very suitable for use in rural areas because this system is easy to manufacture, generates sufficient electricity, and production costs are relatively low. Based on the above, it is necessary to design turbines that support this process system, including Kaplan-type turbines. This study aims to determine how much power the turbine can generate. The methods used in this research are the planning method, the design method, the testing method, and the analysis method for the Kaplan turbine design results referring to the results of initial observations, which show the height of the waterfall. The primary data collection is carried out through direct observation of the research object to determine the geographic location conditions and the ideal micro hydro power plant path. A designed Kaplan-type water turbine is in such a way that there are no errors in the design (for example, the manufacturing costs), and a design is carried out. 1) with an output of 1.2 m3/s and head efficiency (Heff) = 18.9 m, specific rotation (Ns) = 153.3 rpm. Control swing height (B) = 0.069 m, and the Kaplan turbine were chosen for planning the Brantas river flow micro-hydro power plant, Batu City – Malang. The potential that can be generated based on manual calculations is 124 KW, 1500 rpm turbine rotation with an efficiency of 0.85% - 0.90%.
