Abstract

5S is a work culture from Japan that is easy to apply in daily activities, the 5S concept is simple so that it is easy for anyone to understand and understand. The introduction of 5S to Trimitsa Plus Vocational High School students was preceded by introducing what S consists of five parts, namely Seiri, Seiton, Seiso, Seiketsu and Shitsuke. The implementation of community service activities for SMK Plus Trimitsa students is a form of the JGU campus' contribution to the surrounding environment. This activity involved JGU campus students and lecturers who served as material presenters, escorted educational games about 5S and also helped implement 5S in the SMK Plus Trimitsa workshop. Students of SMK Plus Trimitsa are given the opportunity to ask questions and answers about 5S so that they can have the same understanding as the presenter of the material and games related to 5S, namely the game of arranging numbers and letters from boxes containing scattered numbers and letters. The aim is for students to be able to understand that there is a difference between messy and tidy working conditions where if a messy work environment will make it difficult for us to work.

Abstract

Hands are one part of the human body that has an important role in human daily activities. A lot of people have experienced hand disabilities in Indonesia, which is 158,000 per year. This can reduce an individual's quality due to limitations in carrying out activities. So as to help bring prosperity to the people of Indonesia by giving them tools that can support their lives. The purpose of this design task is to make a mechanical hand-made product that is affordable to all Indonesians by providing a low price product. The step of making this product is doing a product selection from mechanical prosthetic hands based on the design method that is identifying customer needs, technical specifications, concept alternatives, concept selection, selected concepts, selected concept analysis, prototyping, product printing, product testing, and product evaluation. Based on the results of the process, a mechanical prosthetic hand is obtained on the alternative concept 2, which will then be tested with consumers. That mechanical prosthetic hand was tested at Mas Muhammad Andika with the result of the movement of taking a tissue, taking food, lifting a bottle, moving a bucket, and lifting a bag. From the results of the tests carried out that there is an evaluation that can be developed on the product that the width of the grip is too narrow, which is 4 cm, so that it is only limited in the size of the grip, it is necessary to develop the second alternative hand model.

Abstract

In this COVID-19 pandemic season, there are still many people who tend to lack awareness in complying with health protocols, especially in terms of crowding and maintaining hand hygiene. Many innovations for hand washing facilities have been made in tourist places, restaurant toilets, malls, and even places of worship. However, during the current Covid-19 pandemic season, have these placements and tools been able to break the ropes of spreading the virus? The answer is that it is still not enough, because the hand washing place is still touched by many hands. Even though some have used automatic or touchless hand washing stations, the purchase of these tools is quite expensive among the surrounding community. Therefore, in this project we intend to break the rope of the spread of the coronavirus, by designing an economical touchless hand washing sink. Then, after the tool was completed, the grant process to the party in need, namely SMK Global Prima in Tambun Utara, Bekasi Regency, was carried out. Although on a small scale, we hope that this effort can be useful for the students involved, the partners of SMK Global Prima, and the community in general.

Abstract

The selection of an appropriate number of blades for a propeller is a critical factor in the design and performance of UAVs. This study aims to analyze aerodynamics. The analytical methodology employed in this research involves computational fluid dynamics (CFD) simulations using state-of-the-art software. A parametric study is conducted to evaluate the effect of different blade numbers on various aerodynamic performance metrics, such as dynamic pressure, static pressure, velocity, and force (Y). These simulations are carried out over a range of operating conditions, including varying airspeeds and altitudes. Our findings reveal that the number of blades significantly influences the aerodynamic characteristics of the propeller. Based on the CFD results, the type of propeller generates a different characteristic of aerodynamics. It will produce more static pressure, dynamic pressure, and velocity if we add the number of blades to it. But, with the CFD process we know that if we need to generate more force, especially in the (Y) axis as the representation of thrust on UAV, we need to consider using a propeller with a 2-blade or 4-blade that generates more thrust efficiently with 367.79 N and 450.59 N respectively rather than 3-blade or 5-blade. Because if the number of blades is added it will cost more pressure either on dynamic or static and velocity value but not following by force (Y) value. Using 200 the trajectories are enough to represent the aerodynamic characteristic produced by each type of propeller.

Abstract

This study aims to carry out pneumatic trainer motion simulations using Festo Fluidsim 3.6 software programming simulation. The trainer design has three main parts, namely a frame made of iron, a programmable automatic control device in the form of a PLC, and the third is a mechanical movement device in the form of a pneumatic circuit. This tool will be integrated into a circuit system, which is then tested with three experiments based on circuit simulations made in the Festo Fluidsim 3.6 software. The test results from 3 simulation experiments show that the PLC control system can send signals to the mechanical motion of a single-acting cylinder. The PLC control system can also send signals to the mechanical motion of a double-acting cylinder with non-simultaneous motion. Other than that, the PLC control system can send signals on the mechanical motion of a double-acting cylinder with simultaneous motion. The three experimental tests found that the number of strokes for a single-acting cylinder was more than that for a double-acting cylinder. The three tests showed that they could move the cylinder well with variations in flow control, namely the flow control openings of 25, 50, 75 and 100%.

Abstract

ABSTRACTGMAW (Gas Metal Arc Welding) is a fast, versatile welding technique that can be used in various positions, but it often results porosity in welded joints.This research aims to analysis of the welded joints of STKM13B pipe and SPD 440 plate using tensile and micro testing, using welding a current of 18 and varying voltages of 110, 130, and 150. The results is the shape of the welded joint of the plate and pipe is perfectly connected, the tensile test results showed that the ultimate strength values for specimen 1, 2, 3 (A110/V18, A130/V18, A150/V18) were (18,959, 27,886, 40,005 N) respectively. The highest ultimate strength values were obtained from the specimens (A150/V18) while the lowest ultimate strength value was obtained from specimen (A110/V18). The use of welding current strongly correlates with ultimate strength value and photomacro results, with higher currents resulting in higher density levels, minimizing porosity, and increasing ultimate strength. Keywords: GMAW Welding, Tensile Test, Macro Optical Test.

Abstract

Heat transfer in air condenser systems is a critical aspect in various industrial applications, especially refrigeration and air conditioning systems. The thermal efficiency of condensers is greatly influenced by airflow characteristics, but airflow velocity optimization remains a challenge due to the trade-off between improved heat transfer and energy consumption. Although previous research has examined various aspects of condenser design, there is still a need to explore the optimal limit of airflow velocity that can maximize thermal efficiency without excessively increasing system workload. This study aims to evaluate the thermal performance of an air condenser in a wind tunnel, focusing on the effects of airflow velocity variations on heat transfer rate and thermal efficiency. The experimental method uses a wind tunnel with dimensions of 280x28x28 cm, equipped with a precise temperature and flow velocity measurement system. The flow velocity was varied from 0.8 to 1.8 m/s. The results showed a significant increase in the heat transfer coefficient (h) and heat transfer rate (Q) as the flow velocity increased. Analysis of Reynolds and Nusselt numbers revealed the transition of the flow from laminar to turbulent, which contributed to the increase in heat transfer efficiency. Comparison of experimental results with simulations showed good agreement in the middle velocity range, but there were deviations at extreme velocities. In conclusion, increasing the airflow velocity proved effective in improving the thermal performance of the condenser, but further optimization is required to balance the thermal efficiency with the energy consumption of the system.

Abstract

Tingginya angka kecelakaan lalu lintas yang melibatkan truk (12%) menggarisbawahi urgensi peningkatan keselamatan kendaraan berat ini. Penelitian ini dilatarbelakangi oleh seringnya insiden akibat patah as atau poros belakang. Untuk memahami fenomena ini, simulasi Finite Element Analysis (FEA) diterapkan guna memvisualisasikan sebaran tegangan dan deformasi pada poros belakang dump truck HINO 500. Analisis ini dilakukan dengan memvariasikan beban 26-35 ton, mencakup beban standar dan overload) dengan tujuan utama mengidentifikasi area konsentrasi tegangan dan potensi titik kegagalan fatik pada poros roda. Hasil penelitian menunjukan bahwa tegangan tertinggi terjadi variasi beban 35 Ton dengan nilai tegangan sebesar 1,76 x 10^8 N/m^2 dengan nilai tegangan tertinggi terjadi pada bagian ujung poros roda gigi dan ujung bagian dekat piringan. Nilai masih terbilang aman karena nilai tegangan lebih kecil dari nilai batas tegangan material yaitu 4,6 x 10^8 N/m^2. Sementara hasil simulasi FEA defleksi sebesar 4,026 x 10^-3 m dan hasil simulasi fatigue failure menunjukan pada variasi beban 26 ton memiliki life cycle terbesar 314.886 dan nilai life cycle terkecil terjadi pada variasi beban 35 Ton dengan nilai life cycle sebesar 46.523.
