Abstract

ABSTRACT Technological developments in the increasingly advanced construction sector cannot be separated from welding. Welding has an important role in metal engineering. A good welding connection will greatly affect the welding of low, medium and high carbon materials in the SMAW (Shield Metal Arc Welding) welding process. The shipping industry in Indonesia uses a lot of 10 mm plate types, in reality welding using 10 mm plate materials is very difficult, especially in determining the number of amperes that must be used so that the welding results are said to be good. The purpose of this study was to determine a good amperage value for SMAW welding using a 10 mm A36 plate material with an E6013 electrode. By using a tensile test and a micro test by first using the experimental material in the form of a plate with type A36 which is welded using an E6013 electrode. With plate-shaped samples totaling 12 pieces using different amperes, namely 70, 110 and 160 amperes. From the results of the study it can be concluded that the best amperage and recommended for use in welding is 110 amperes. With an amperage value of this size, it will produce welding material that is not easily broken. So that in practice in the field, if this ampere value is used, it will produce a better product, more durable and have a better product selling value. Keywords: A36, E6013, Ampere, Welding.

Abstract

ABSTRACT Boiler is a high pressure vessel or tank that functions to produce hot steam. Problems that often occur in the field on boiler machines are not efficient well when the work system or operating process in the field, especially when the process is under operating conditions on a fire tube boiler engine always experiences heat loss in the steam or steam system and the fuel system which affects the efficiency of the engine. fire tube boilers are not optimal for steam output. Therefore, with these conditions, it is necessary to calculate the efficiency of a good fire tube type boiler engine in order to meet the appropriate efficiency value standards in the operating process in the field. The method used in this study is the calculation of efficiency carried out by two methods, namely the direct method and the indirect method. Based on the results of efficiency calculations using the direct method, the efficiency value is 81.04%, while the results of calculations using the indirect method are 85.65%. The results of the calculation of efficiency values ​​that have been carried out from two methods, namely the direct and indirect methods meet the standard efficiency value of the boiler engine ≥ 80 %.

Abstract

ABSTRACT Parkinson's disease is the second most common neurodegenerative disease in humans after Alzheimer's disease. The disorder causes patients to experience a variety of symptoms, including intellectual and behavioral disturbances, dementia, memory loss, muscle weakness, stiffness (slow and stiff movements), and tremors. This study describes how to detect Parkinson's disease using Open CV and how geometric images can be used to detect and predict Parkinson's. We will then examine our image dataset collected from both patients with and without Parkinson's. After reviewing the dataset, I will teach you how to use the HOG image descriptor to scale the input image and then how we can train the Random Forest classifier over the extracted features. The expected result is that the system can detect and predict Parkinson's disease from a patient with an accuracy rate above 90% Keywords: Parkinson's detection, HOG, OpenCV, Deep learning.

Abstract

Abstract Currently radar is widely used in various fields such as meteorology, military, police, shipping, aviation, agriculture, disaster, and research. Meanwhile, currently the use of radar is still in the form of sectoral, partial, and fragmented so that the use of radar data is only internal. With Indonesia's geographical condition which is very broad and the integration and distribution of radar data has not been maximized, this has resulted in the lack of geographic area of ​​Indonesia that is reached by radar. The use or exchange of radar data still uses client-server-based information technology, and with centralized storage which has risk factors for information security and privacy that are vulnerable to being misused or exploited. In addition, there is the possibility of data loss which makes it difficult to get data back, even when you have implemented a backup system with cloud or other protection, there is still a risk of complete data loss when compared to implementing a decentralized platform. Therefore, it is necessary to integrate and distribute radar data with a decentralized platform so that the radar data is not sectoral, partial, and fragmented. This integration and distribution of radar data will later be able to maximize the use of cross-field radar so that one radar can be used more optimally for all fields including meteorology, military, police, shipping, aviation, agriculture, disaster, and research. One technology that can be used for the integration of radar distribution is blockchain and cryptography. Blockchain and asymmetric cryptography in addition to increasing data security, can also guarantee that data entering the blockchain system comes from the correct source. The larger the bit asymmetric cryptographic key used, the more secure the data. Keywords — Radar, Blockchain, Cryptography, Integrated Distribution.

ABSTRACT Power flow analysis is important in planning in order to get a good electric power system. In planning the electrical system for the Tujuh Bukit Power System project with a 20kV system network located in Banyuwangi, East Java, a power flow simulation for a single line diagram will be carried out using the ETAP 12.6 software with the Newton Raphson method. The simulation results which consist of 22 buses show a voltage drop on the 0.4kV_ADR MCC Busbar2 bus and 0.4kV_50-MCC-01 Busbar2 bus. As a system improvement, the 0.4kV_ADR MCC Busbar2 bus will be installed with a 500 kVar capacitor bank to raise the voltage profile from 376.3 V to 385.56 V. While on the 0.4kV_50-MCC-01 Busbar2 bus, a 100 kVar capacitor bank is required to increase the voltage from 382.2 V to 384.16 V. After the repair, the power supplied to the system is 3589.6 kVA with a power factor of 90.5% lagging. As well as the reduction in the total value of system power losses from 58.1 kW + 242.2 kVar to 49.3 kW + 200.8 kVar. Keywords: Power flow, Netwon Rapshon, Simulation, Software ETAP 12.6
