Abstract

Some efforts made in restoring peatlands include moisture restoration, replanting, hydrological restoration, monitoring, and evaluation using technology to obtain periodic condition data. The implementation of the Water Level Logger (WLL) for monitoring groundwater levels in peatlands still faces issues because the sensor installation points are not served by cellular communication networks for data transmission. This research aims to implement a Low Power Wide Area Network (LPWAN) as a low-cost infrastructure used in applications for monitoring water levels in peatland. The method in this research is an approach to develop LoRaWAN gateway devices and servers using ChirpStack, equipped up to the application layer as supporting infrastructure for self-hosted groundwater level monitoring tools integrated with a time-series database and displaying measurement data on a dashboard periodically. Based on the tests, the average measurement of the Received Signal Strength Indicator (RSSI) obtained at the farthest distance of 3 km was -116 dBm, where the RSSI value also decreased with each additional distance, and the Line-of-Sight (LOS) condition significantly affected the RSSI value. This research shows that a real-time peat groundwater monitoring system has been successfully built at a low cost using self-hosted LoRaWAN gateways and servers, while maintaining reliability.

Abstract

This research aims to analyze the bending strength of composite materials based on corn fiber and fiberglass with Lycal resin, which are produced using two methods, namely vacuum bagging and vacuum infusion.Composite materials are increasingly being used in various industries because of their light and strong haracteristics. In this research, corn fiber was chosen as a natural reinforcement material because of its abundant availability and economic potential, while fiberglass was used as additional reinforcement to increase the strength of the material.The composite manufacturing process is carried out using two different methods, namely vacuum bagging and vacuum infusion, which are then tested using the ASTM-D 790 standard to determine the mechanical characteristics of the material, especially in terms of its ability to withstand bending loads. Apart from the bending test, material density calculations were also carried out to compare the weight and density of the two manufacturing methods.The test results show that the vacuum infusion method producescomposites with higher flexural strength than vacuum bagging. This is caused by a more even distribution of resin and minimal air trapped in the material structure during the vacuum infusion process. The composite produced from this method also has a lower density, making it lighter but still mechanically strong.It is hoped that this research can contribute to the development of natural fiber-based composite materials that are environmentally friendly and efficient, and have the potential to be applied to the aerospace industry, especially in the manufacture of UAV structures

Abstract

This research aims to prevent unscheduled maintenance by determining the optimal maintenance time to plan preventive maintenance on the fuel system of the KT-1B aircraft. Fuel System components include Engine Driven Pump, Fuel Control Unit. The methods used are Fault Tree Analysis (FTA), Failure Mode and Effect Analysis (FMEA), and Weibull Distribution. This method is to determine the factors causing failure, calculate the failure rate, and system reliability. Factors causing fuel system failure are influenced by age, damaged seals, vibration. The level of reliability of the Fuel System decreases with the length of use. Where the system will experience a critical period when it reaches operational time, namely engine driven pump = 1010 hours with a reliability value of 70%, fuel control unit = 1637 hours with a reliability value of 70.1%. After knowing the critical mass limit of the components, Preventive Maintenance planning will be carried out on the parts and components that cause failure, namely by cleaning the engine driven pump components and the fuel control unit by periodically checking the parts on the KT-1B aircraft.

Abstract

Thermal efficiency is a dimensionless measure that shows the incoming heat is the energy obtained from the energy source. The cooled output may be either heat or work, or it may be both. The CFM56-3 engine is a turbofan jet engine with large bypass capacity, dual rotor used with advanced axial flow technology designed for use on BOEING737 aircraft and all its variants. The purpose of this study is to determine the thermal efficiency of a turbofan engine, the causes of decreased performance of a turbofan engine and efforts to overcome it. This research is a qualitative and quantitative research using primary data and secondary data. Data collection techniques used are field studies, literature studies, as well as discussion and problem analysis. The field study in this research is to make direct observations of the processes that occur in the field. The results of this study can be concluded that the thermal efficiency of the Boeing 737-500 aircraft occurs the higher the difference between the incoming energy and outgoing energy through the compressor is 49.11% and the turbine is 64.01% the system produces the ideal thermal efficiency value of the Brayton cycle of 70 ,51% produced will be higher while the actual thermal efficiency of the Brayton cycle of 44.0% has decreased compared to the ideal thermal efficiency. The comparison of the ideal thermal efficiency of the Brayton cycle and the actual thermal efficiency of the Brayton cycle is 26.51%, meaning that efficiency can still be increased by as much as possible returning the component dimensions to their proper condition. The cause of the decreased performance of the turbofan engine is a change in dimensions due to frictional materials; wear and tear caused by continuous operation; as well as incorrect operating steps on the turbine engine and efforts to overcome them are periodic inspections of each turbofan engine components and using accurate measuring instruments

Abstract

Amphibious aircraft are types of aircraft that can land on land and in water with floating components (floaters).  Amphibious aircraft are capable of landing both on land and water using float-equipped structures. In its operation, it is likely to have a bending force on the floater. When the floater is replaced with a hybrid composite, it is likely to have a light load and high beding value bending value. During operation, the floater is subjected to significant bending forces. Replacing the floater with a hybrid composite results in a lighter structure with improved bending strength. This study aims to analyze the bending test of hybrid composites reinforced with carbon fiber and aluminum faceplates. This study aims to evaluate the bending strength of hybrid composites reinforced with carbon fiber and aluminum faceplates. The method used in this study is vacuum bagging, where the sample is combined with epoxy resin and mixed with carbon nanotube (CNT) nanoparticles and aluminum powder (AL). The study was conducted with adhesive resin, surface treatment and the addition of nano particles to determine the effect of the bending strength of the composite. This study aims to analyze the effect of surface treatment and nanoparticle addition on the flexural strength of the hybrid composite.  The results showed that had a high bending value compared to the variation of specimens without surface treatment or nano particles. Specimens treated with surface modification and nanoparticles exhibited higher bending strength than those without either treatment. The highest bending stress value was obtained by the CNT variation of 133.89 MPa followed by the variation without nano particles of 98.59 MPa, then the variation without surface treatment of 91.76 MPa, and the one with the smallest value was the AL variation of 61.02 MPa. Macro photo analysis after bending test shows the presence of Mixed-mode defects in the specimen. This shows that specimens that have surface treatment and nano particles have better bonds and are able to fill the void in the empty area, so that the bending strength is good. This study provides an important contribution to understanding the variation of adhesives and nano particles on the bending strength of hybrid composites. This study offers preliminary insights into how variations in adhesives and nanoparticles influence the bending strength of a specific hybrid composite system.
