Abstract

In development planning in the mechanical industry or civil engineering construction, it is very common to use the properties of the iron rod material which can deflect or what is known as a cantilever. The factors that affect the size of the force exerted on the stem are directly proportional to the amount of deflection that occurs. In other words, the greater the load experienced by the rod, the greater the deflection. Deflection of rods plays an important role, especially in building construction, wherein certain parts such as the shaft, deflection is very undesirable. Because of deflection, the work of the shaft or construction will be abnormal so that it can cause damage to the construction or other parts. This study aims to find out how much deflection of cantilevered rods using metal plate material when given a distributed and concentrated load. Based on the data obtained from the research process, the results in this study indicate that there is an effect of slackening distance on the iron plate with 3 variations in loading. The results showed that the loading rate affected changes in the angle of deflection of the iron plate in every variation of the number of plates used. The greatest effect occurred in the plate variation size of 0.8 mm with a loading level of 3 kg, namely 3.64 x 10-5 and the smallest effect on plate variations was 1.8 mm with a loading rate of 3 kg, which was 0. The results showed that the loading rate was spread across 3 plate variations. with a load of 3 kg spread over 3 points with a distance of 15 cm from point 1 to point 3. The biggest deflection effect occurs in plate variations of 0.8 mm which is 3.64x10-5 and the smallest effect on plate variations is 1.8 mm with the same load of 0.

Abstract

Jig is a fishing rod that is usually used to catch squid or cuttlefish in the form of fish, shrimp, or others. This study aims to determine the effect of differences in the shape of the surface of the jig on the flow pattern of freshwater fluids. The study used a variation of 3 jig surface shapes with the same length, namely 7 cm, 1 cm wide. The angle of inclination of the jig includes 15⁰ and 30⁰. The type of flow is laminar conditioned using a volume flow rate of 76.60 liters per second. The jig is conditioned to move up and down using an electric motor. The flow patterns formed were analyzed using visual tests and measurements using Kinovea 0.8.15. The results showed that the shape of the surface of the jig had an effect on the fluid flow pattern. The highest wave occurs at jigs 3 with 15⁰ variation with a wave crest of 4.55 cm, while for jigs 1, 30⁰ variation produces the lowest wave of 1.51 cm. Keywords : Jigs, shape jigs, angle jigs, flow patterns, waves

Abstract

Unwanted grass growth on land will cause problems for humans. Generally, the sickle is a tool that is often used to cut grass. The use of a sickle has several disadvantages, namely using manual labor, in some cases there is a narrow-angle that makes it impossible to cut with a sickle. This study uses variations of 2, 3, and 4 blades with motor rotation speeds of 666 RPM, 1713 RPM, and 3454 RPM. The data collection method is done by determining the mass of grass by 25 grams, then the grass is arranged and moved closer to the blade with a cutting time of 10 seconds. The shortest cut grass results were obtained on the number of blades 4 with a motor rotation speed of 3454 RPM, which is 10.92 mm. The difference in mass of grass clippings in the variation of blade 4 with RPM 1 and 3, which is 4 grams, indicates the overall cut grass Keywords: blade, motor rotation speed, grass cutted

Abstract

Window film is a thin layer on car glass that functions as a medium for repelling sunlight. This study aims to determine the effect of percentage of window film density on the thermal and lighting distribution of the vehicle cabin. This research was conducted using a room model measuring 50x50x30 cm. The variation of window film uses two brands of Ultima and 3M, with the respective percentages of 40% and 60%. When the experiment was carried out in an open space, the irradiation process was carried out for 2 hours using the sun's rays at 11.00 - 13.00 WIB in each variation. Temperature measurement uses a digital thermometer on the surface of the coated glass (T1) and indoors (T2), while the measurement of light intensity uses a lux meter that is placed outdoors (I1) and indoors (I2). Data analysis using the equations of temperature rate and effectiveness of heat and light reduction. The results showed that the difference in the percentage of glass film density affected the rate of heat transfer and the intensity of the light entering the room. The heat transfer rate tends to increase in Q1 with a value of 58375.61 joules, and decrease in Q2 with a value of 1160.46 joules in the variation of 3M glass film brands with a 60% concentration level. Meanwhile, the average temperature increase rate is 0.002 ℃ / minute for all variations of window film brands with a light intensity of 0.007 - 0.008 lux.

Abstract

Tobacco stems contain up to 35-50% cellulose, make them ideal for use as a renewable energy source. Tobacco varieties Na Oogst and Voor Oogst are characterized by their growing season. This study aims to obtain the effect of comparison of tobacco variants on the characteristics of bioethanol products. Each type is distinguished by its particle size (a) : 8-10 mm, (b) : 1.19 mm, (c) : 0.25 mm. A total of 100 grams of material was delignified using 1 liter of 4% HCl for 30 minutes. The material is then fermented using 10 grams of yeast for 10 days and distilled at a temperature of 78-80oC. Using Image J Software, the volume of the product is measured and then burned to examine the characteristics of the fire based on the duration of the flame, the percentage of color, and the dimensions of the flame. The volume of the product is also affected by particle size. The Na Oogst variant had the maximum volume with a particle size (c) of 120 ml and the lowest volume with a particle size (a) of 29 ml. The best fire characteristics were obtained in the Voor Oogst variant with particle size (c) and a blue flame percentage of 48 percent, whereas the Na Oogst variant with particle size (a) and a blue flame percentage of 10.2 percent had the lowest blue flame percentage.
