Abstract

The problem in this research was the low performance of student in the Practical of Mechanical Workshop Mechanical Engineering Study Program Polytechnic State of Padang in the implementation of learning practices that affected by occupational safety and health , student discipline, and guidance of lecturer. This study aims to analyze the relationship occupational safety and health, student discipline and guidance of lecturer with the student practice performance of mechanical workshop Mechanical Engineering Study Program Polytechnic State of Padang. This study was a correlational study with a quantitative approach. The population of the research is all the student of 2016 with consisted of 125 people. The sampling technique used is proportional random sampling, that 96 people as a sample and 29 people were respondents taken from the population. Data were collected through a questionnaire that had been tested for validity and reliability. The results showed that, 1) there is a strong and positive correlation between occupational safety and health with the student practice performance with rhitung (0.463)> rtabel (0,199); 2) There is a strong and positive correlation between discipline with performance of students practical with rhitung (0.479)> rtabel (0,199); 3) There is a strong and positive relationship between the guidance of lecturers with the performance of student practical with rhitung (0.451)> rtabel (0,199); 4) there is a very strong and positive together occupational safety and health discipline students and guidance of the lecturer with the performance of student practical rhitung (0.525)> rtabel (0,199).

Abstract

The power produced by a hydrokinetic turbine depends on the interaction between the rotor and water. Therefore, the optimal rotor geometry must be designed and built to capture maximum water energy and convert it into usable energy. Hydropower is one of the potential renewable energy that can contribute to the need for electricity. Hydropower generator is pollution free so this generator can answer environmental problems and the availability of renewable energy sources. The aim to be achieved in this study is to produce a turbine hydropower with good performance if it operates on an irrigation channel and is applied as a power plant. This research was developed to get the right specifications for the use of hydrokinetic turbines in the irrigation canal area. There are several methods carried out in the design of hydrokenetic turbines, namely by designing blades based on the shape of water flow, repairing the transmission system, and selecting the right generator. In this study, we tested the sweet lemon irrigate applied and tested in the area of ​​Padang Sumbar Sweet Limes Pauh, the results obtained were that the turbine can produce power of about 12.6 watts.

Abstract

In this day and age people decorate homes with flower pots and many models of flower pot place creations. Usually the place to put flower pots in the form of a circle and to make a circular iron is made manually requires energy and a long time. A bending machine is needed to make concrete iron circle creations. The aim of this research is to produce a rotary bending machine that is able to work efficiently in forming a concrete steel circle. The method used in this study is a practical method that is doing machine design and continued with the manufacture and field testing. The working principle of this machine is to use a motor that functions to move the Gearbox and continue the rotation to the shaft, then the shaft rotates and the bending mall rotates and makes the steel concrete come round and circular. The conclusion is (a). This concrete steel rotary bending machine has dimensions of 550 mm x 550 mm x 1000 mm with an electric motor drive power source (b). The results of the bending process using a concrete steel rotary bending machine are far more efficient than doing manual bending

Abstract

This pneumatic system tofu press machine is a press machine that is used to compress tofu starch with a capacity of 50 kg to make tofu that is ready to be marketed. The pneumatic system tofu press machine is made to make it easier to press tofu. Previously, tofu was pressed manually, namely by using a stone as a tofu press which resulted in the length of the tofu compaction process. Pressing with stones can also cause work accidents. This tofu press machine uses pneumatics as a punch driver which will press the tofu. The way this tofu machine works is by pressing the on button on the machine then the punch will move down towards the tofu essence and press the tofu. Punch paused for a moment to make sure the tofu blended in perfectly. Then press the off button on the machine to return the punch to its original position. This pneumatic system tofu press machine can reduce work accidents, lighten work, shorten processing time and is also more hygienic because it uses air as a punch driver.

Abstract

Palm is a type of palm whose potential for high economic value and can thrive in Indonesia. Nagari Andaleh Baruh Bukik is an area in Tanah Datar District that is a center of palm crop production and has the potential to be developed by its economy. Seeing a promising market, the idea was born to process ant sugar into brown sugar cubes by making a brown sugar cube printer. The manufacture of brown sugar cubes using the manual press method with a pressing system utilizes the principle of the 2nd type of leverage, where the load point is between the power point and the fulcrum. This pressing system works if the lever is pulled by the operator according to the specified depth limit, to restore the position of the lever to its original position is to take advantage of the spring force. It takes about 392 N to press the mold. By doing the calculation so that a mechanical profit is obtained 3 times, the total force required to press is 130.6 N. The safety factor equation is 69.76 N/mm2 ≤ 200 MPa with the largest curved moment being 130.87 N/mm2, so this tool is safe and will not be bent. Power arm length: 34.5 cm, weight arm length: 11.5 cm. Designing components and assembling brown sugar cube printers using the SolidWork application.
