Abstract

Abstract The characteristics of young coconut skin, which has high fiber content, are often an obstacle factor in the peeling process. Setting the rotation speed and angle of the slicing knife are important parameters that affect the cutting style of the coconut peeler knife. This study aims to determine the production capacity, electrical power requirements, and physical quality of the peeling results on the young coconut peeler machine. The experiment was carried out using variations in the sharpness of the blade angle, namely 10o, 15 o, and 25 o. Young coconut material is selected with relatively the same diameter and weight. The results showed that the knife angle variation of 15o had the highest production capacity of 499 pieces/hour. Research on economic analysis generates Rp. 1.093/hour while for electric power or the cost of electricity required per unit is Rp. 19/piece. This research can be concluded that the variation of the angle of the blade that has optimum performance is shown in the variation of the angle of 15 o. Keywords: Machine, Young Coconut, Angle Variation, Production Capacity.

Abstract

ATV is a vehicle with engine drive using a combustion engine, ATV is designed to have maneuverability supported by a lightweight and strong frame construction, a tough engine, and an adequate suspension system. Almost similar to cars, ATVs have applied Aeckermann's steering and independent suspension. At first ATVs were only used by plantation owners for their means of transportation, but along with the development of the times ATVs can be used for many activities in the automotive world such as racing, motorbikes for nature explorers, operational vehicles for the SAR team or in Indonesia many are rented out for cross-country activities at tourist sites. This study discusses the effect of the load on the performance of the steering system on a 110 cc ATV motorbike which is planned to be modified into an electric motor as the main engine. To measure the load on the performance of the design steering system using a digital dynamometer that is linked from the steering wheel to the ATV motor frame, to determine the weight of the steering wheel against the load, it is done with variations in the steering radius of 100, 150, 250, and 350 and giving a load of 0, 50, 75 kg. Later the digital dynamometer will read automatically when the variation of the experiment is carried out. The purpose of the study was to obtain the effect of the weight of the load on the performance of the motor steering system on a 110 cc ATV motor vehicle. In this study, changes in the load received by the steering wheel are expected to affect the magnitude of the moment to be received. This parameter is one of the performance of a steering system. The increase in payload causes the steering system to become heavier. This is due to the influence of the weight of the load pressing the seat (load point) which is forwarded to the vehicle frame, this is due to the gravitational force of the load on the vehicle, so that the steering system directly receives the load pressure which is transmitted to the tires. From this steering tire gets heavy friction from the road surface, so turning the steering wheel becomes heavy or difficult. Keywords: load, steering, ATV, performance

The study was conducted in a true experiment with variations in the ratio of the addition of banana fiber by 1.6; 2.5; and 3.3 gram. applying pressure to each specimen in variation 3; 5; and 7 N/m, the compressive strength test was carried out to obtain the mechanical properties of the product. The results showed that the percentage decrease in mass and product dimensions increased along with the pressure applied to the specimen. Depreciation of the mass of brick products is accompanied by changes in the value of the water content of the product. The compressive strength of the bricks increases with the percentage of the given fiber weight. Keywords: compressive strength, concrete brick, fiber, kepok banana (musa pasadisianca), mix ratio.

Abstract

The contact between ball and tennis racket is a collision phenomenon. The ball exerts a force on the racket which causes deflection. This study aims to obtain the deflection characteristics of a tennis racket due to ball contact. The research was conducted by experiment with Kinetic brand rackets. The racket is clamps on the grip. The ball used is Nassau brand with 0.058 kg of mass. Free fall is arranged 1, 2 and 3 meters heights, with 3 hitting points on racket string. The deflection measurement uses the pen method at 5 points on racket frame. Five points are arranged sequentially from the grip with 6 cm distance. Data collection was carried out with 3 repetitions to get average value. The deflection was measured using a caliper with 0.01 mm accuracy. The results show that the deflection has a linear characteristic and depends on the momentum of the ball

Abstract

A matic motorcycle 110 cc is one of kinds of motorcycle that many used by the modern people, especially for the narrow streets with high level mobility. One of aspects to beconsidered in this vehicle design is a level of comfort and safety in reducing the vehicle due to environmental conditions. The purpose of the research is to get the characteristics of shock breakerin matic motorcycle 110 cc with three motorcycle brands due to road profiles. The research was conducted with road profile model (flatten, slightly wavy and wavy) at Rpm speed (1700, 3500, 4000 and 5000). Vibration was calculated based on the speed of circle engine (Rpm) using vibration’s meter. Measurements were done at 3 points in the shock beaker, rider and passenger with 60 seconds 20 seconds. The results showed that the greater the engine speed (Rpm), the vibration tends to be smaller, whereas the smaller the engine speed (Rpm), the vibrations tend to large.

Abstract

The study was conducted with a pyrolysis experiment where temperature variation of 250oC, 350oC, 450oC, and 550oC and tire sample mass of 300 gram. The heating temperature comes from an electric heater equipped with a control system. The temperature was measured using K type thermocouple. The residence process was carried out for 120 minutes measured using a stopwatch. The tire and char sample volume were measured using measuring cups and the sample mass was measured using the scales. Tests on char quality characteristics include flame, coal temperature, flame time, and ash residue. The results showed that the higher the process temperature in pyrolysis, it affects char characteristics on the rotary kiln. The percentage of char mass losses tends to increase with the high pyrolysis process temperature. Char shrinkage factor tends to decrease as the percentage of mass loss increases. Char porosity tends to rise as the percentage of mass loss increases. The percentage of blue color on the char flame tends to rise in accordance with the addition of the percentage of mass loss and vice versa the percentage of red color on the char flame tends to decrease. The combustion temperature of char combustion tends to increase according to the high temperature of the pyrolysis process. Coal char's flame time tends to increase as char porosity increases. The ash of combustion yield tends to decrease as the percentage of mass loss increases.
