Get PDFPengendalian Tangan Robot Perakit Pada Disain Computer Integrated Manufacturing Berbiaya Rendah (CIM) Menggunakan Visual Basic Dan Arduino
Get PDFComputer Integrated Manufacturing (CIM) merupakan suatu teknologi fabrikasi gabungan yang unit-unit prosesnya dikendalikan oleh satu komputer. CIM merek Intelitek sudah terkenal dan meskipun sangat mahal namun tetap menjadi acuan untuk pembelajaran bidang manufaktur khusunya teknik industri karena kecanggihan software simulasi dan modul praktikumnya berbasis website. Tujuan jangka panjang dari penelitian ini adalah membangun CIM alternatif yang murah, tanpa menyertakan software simulasi, dengan menggunakan microcontroler Arduino Due 32-bit agar menciptakan produk pesaing yang meskipun jauh lebih murah dari merek Intelitek, namun tetap dapat mengantarkan esensi pembelajaran CIM pada level dasar. Penelitian ini bermaksud membangun 4 Robotic Arm untuk stasiun perakitan yang dahulu secara tradisinya hanya untuk kebutuhan material handling atau dengan istilah loading unloading. Benda yang dirakit pada penelitian ini adalah Satu Balok Tetris 4 Susun. Hasil penelitian menunjukkan terjadi 50% kegagalan rakit disebabkan konstruksi Robotic Arm yang suaian antar komponennya terlalu longgar meski sudah dikencangka

Get PDFThe light in the workspace should be set for a comfortable and healthy employees. If possible energy saving will be even better. In this research, the object of the case study is Computer Laboratory Room in the Faculty of Engineering UPN “Veteran” Jakarta. Problems were found in Computer Laboratory Room is a waste of energy if the lamp position higher than the lamp that hung using a rope. The electricity wastage would be better if it can be minimized, so that the university can take advantage of the budget is wasted on inefficient lighting for research activities and improvement of facilities in the university environment. So that savings can be achieved then the first step is to determine the formulation of the relationship between the intensity of light, lamp power and distance can use Multiple Linear Regression and Poisson regression methods. After processing the data and analysis can be seen equation fluorescent light: Lux Neon = exp (Y \u27), Y\u27 = 4.248 + 0.04698 Watt Neon - 0.007542 Distance, and spiral lamps equation: Lux Spiral = exp (Y \u27) , Y \u27= 3.385 + 0.06330 Watt Spiral - 0.005169 Distance

Get PDFSTUDY OF THE INFLUENCE OF COVID-19 REPORTING MEDIA ON THE MENTAL HEALTH OF INDONESIAN COMMUNITY WITH STRUCTURAL EQUATION MODEL (SEM) APPROACH
Get PDFThe coronavirus outbreak phenomenon has become a headline that colors the daily news that the World Health Organization (WHO) identifies the virus as a novel Coronaviruses disease (Covid-19) designated a global pandemic. This pandemic has spread to almost all countries globally and infected millions of people in it. This pandemic has spread to almost all countries globally and infected millions of people in it. In a short time, almost all news media reported about the Covid-19 pandemic starting from prevention, positive diagnosed characteristics of Covid-19, and news of the impact that will be felt if someone is known to be affected by Covid-19. The news that circulated not only happened but also much fake news emerged, which caused more pressure on the community. The World Health Organization (WHO) identifies that many of the rumors and misinformation that spread fear in this community mostly come from social media. Therefore, there must be an effort made by a study to find out and test whether there is an influence of the Covid-19 news media on the mental health of the Indonesian people. Based on the results of SEM calculations obtained, media factors that concern mental health are the role of media, content media, media frequency, and media sources. These four things have contributed to mental health factors, namely anxiety, and depression. Depression and anxiety are mental health factor
ANALISIS PERBANDINGAN SIFAT ALIRAN PADA MODEL 2D AXISYMMETRIC DENGAN MODEL 3D DENGAN METODE NUMERIK
Get PDFMany previous studies of ejector have been conducted to understand and maximize the ejector performance. The study can be in form of experiments, analytical, and numerical simulation. The numerical simulation looks for the most effective and efficient effort and time in modeling flow process inside the ejector. Model simplification becomes one of solution in conducting simulation effectively. Three dimensional models in general are applied to an ejector that would be analyzed. These models can be compared to the simpler model, namely axisymmetric 2D model. The current study investigated the comparison between 3D and 2D models using numerical solution. Three types of ejectors from different application were used as the objects of the study. The analysis was conducted by comparing the qualitative and quantitative results. The results show that qualitatively the 2D axisymmetric model has good comparison to the 3D model. Quantitatively, 2D axisymmetric model has good similarity to 3D model for ejector performance parameters, such as entrainment ratio and Mach number with biggest difference of 5.7%. However, the velocity and pressure distribution have bigger discrepancies at both axial and radial directions at the area with extreme change, such as at throat nozzle. It can be concluded that the 2D axisymmetric model can be used as substitution of 3D model when the objective is only to obtain ejector performance and qualitative study

The Design of 3 GT Fishing Vessels Using DC Electric Power as Driving and Electricity
Get PDFThe purpose of this study was to design a 3 Gross Tonnage (GT) fishing boat with a speed of 6 knots to obtain the shape and size of the vessel that is suitable for the water area that using the solar panel energy system. The ship was planned to travel about a maximum of 18 Km from the departure point. The steps of the research method for the design of fishing vessels include determining the principal size of the ship, making line drawings, drafting a general plan, construction design, ship tonnage capacity, electricity requirements, and then designing solar panel energy systems. This research resulted in a ship design with a length of 8 meters, 1.75 meters wide, and 1.3 meters high. Those specifications are used as constraints to determine the number of solar panels and batteries. To satisfy all of the goals, the 3 GT boat has limited 0.9KWh solar panels to travel for 9.7 NM (18 KM) at a speed of 6 knots, forcing daytime and night fishing fishermen to idle for 1 day. The difference is in the number of night fishing batteries that are 49% more than the daytime fishing which using 25 pcs 3.2V 100Ah. With the use of 51 pcs of battery, night fishing can move into daytime fishing so that it can fish more frequently than night fishing mode onl
