Pengaruh Nozzle Dan Pengaruh Variasi Nozzle Terhadap Mini Turbine
Utilizing hydrokinetic energy through water turbines is a promising solution for generating renewable electricity. Water turbines play a crucial role in converting the kinetic energy of water into mechanical energy that can be used to drive electrical generators. This research focuses on the optimal design of a nozzle for water turbines to enhance the performance of hydrokinetic energy. The main objective of this study is to design and analyse an efficient nozzle for water turbines. The nozzle has a critical function in directing the flow of water efficiently and increasing the flow velocity into the water turbine. In the nozzle design, various parameters such as nozzle shape, diameter, angle, and length are considered to achieve optimal performance. The results of this research demonstrate that an optimal nozzle design can significantly enhance the performance of hydrokinetic energy in water turbines. An efficient nozzle design can increase the flow velocity, thereby resulting in increased power output from the turbine. Moreover, the use of genetic algorithms in optimizing the nozzle design aids in efficiently obtaining an optimal design

Analisis Dampak Perubahan Arus Pengelasan Terhadap Kekuatan Sambungan Las Pada Material Stainless Steel 316
In a situation of increasing urbanization in the capital, the demand for decent and quality housing is also increasing rapidly. This increase was in line with increasing market demand for specific construction products such as railings, doors and windows which are of good quality. The research method and data collection will start from nine pairs of 316 stainless steel plates which will be welded using SMAW welding. Welding on stainless steel plates will be carried out with varying welding currents of 60 A, 70 A and 80 A. Each of these welding currents will be carried out on three stainless steel plates. The results showed that the use of a higher variation of welding current in the welding process resulted in a higher strength of the welded joint. The elastic modulus can decrease due to several factors such as the presence of microscopic cracks, changes in crystal structure, or changes in the bonds between atoms or molecules of the material. The strength of welded joints in stainless steel 316 material can also be affected by other factors besides variations in welding current. Parameters such as mains voltage, welding time and type of electrode also contribute to the strength of the welded joint

Pengaruh Kecepatan Potong terhadap Kekasaran Permukaan Cetakan pada Mesin Milling CNC
This study aims to determine the appropriate cutting speed in the milling process to produce good die surface roughness on 6061-T6 aluminum workpieces and to determine the effect of the cutting speed parameter of 30-50 mm/minute on surface roughness. Types of research methods and data collection will begin through a literature study process, by making working drawing designs then making chisel grooves and calculating VC and other parameters, followed by the milling process. Based on the results of the test data obtained, it shows that (1) Based on the graph obtained from the data table, the cutting speed (Vc) from the comparison of the base and wall between the core and cavity has where in this position the cutting speed (Vc) is 50 mm/min, which is the cutting speed (Vc) is the most optimal with engine speed (n) 1592.36 Rpm, Infeed speed (Vf) 636 mm/rev, and a constant Depth Of Cutting at 0.5. (2) The conclusion of this cutting speed (Vc) is that a high cutting speed will take faster machining time and have smoother surface roughness.

Studi Komparasi Pengaruh Kecepatan Potong Tinggi dan Konvensional terhadap Kekasaran Permukaan dan Waktu Proses Bubut
The number of manufacturing industry growth in Indonesia is increasing over time. Based on the data obtained, the manufacturing industry in Indonesia recorded growth of 3.9% from July to August 2020. This study aims to analyze the effect of cutting speed on the surface roughness of S45C steel and to find out the production time for high speed cutting machining processes. This study used an experimental method, using a transverse/cylindrical turning method. Transverse turning is a lathe process when the cutting tool moves parallel or linear to the spindle axis. The test specimen will be machining starting with determining the independent parameters; feed (f) 0.2mm/rev, depth of cut (depth of cut) 0.1mm, length of cut (Lt) 100mm, then determine the dependent parameter by varying the speed of cut (Vc) starting from 125m/min to 625m/min. Based on the results of the test data obtained, it shows that (1) The higher the cutting speed, the lower the surface roughness value. This is caused by the process of plastic deformation and thixotropy phenomena. (2) The higher the cutting speed, the lower the cutting time. This is caused by the annealing phenomenon during the turning process
