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.

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

Abstract

Research has been carried out with the aim of obtaining the effect of adding "kepok" banana fiber (Musa Pasadisianca) to the compressive strength of the brick. 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

Abstract Railway components especially for parts of that often occur friction and resist when there is a pulling or pushing must have a low roughness to reduce the occurrence wear caused by frictioning and as an indicator good or bad quality of a product. The purpose of this study is to know the effect of roughness level of cutting parameter variation, wet process manufacturing method variation, dry process and nose radius variations of chisel lathe 0.4, 0.8 in the ST 90 The method used in this study is experimental. The independent variables in this study were variations in cutting parameters, nose radius of the tool, and working methods. In cutting parameters, spindle rotational speed (540 Rpm, 800 Rpm, 1500 Rpm), feed speed (0.226 mm/revolution), depth of cut (2 mm) and for nose radius using 0.4 mm and 0.8 mm, there are also variations in wet working methods. process and dry process. After testing is carried out, it shows that on the ST 90 with the wet process working method and nose radius 0.8 turning variation with spindle rotation speed of 1500 Rpm, depth of cut 2 mm, feed speed 0.226 mm/rev has a roughness value of 2.625 µm. Meanwhile, for the highest level of roughness, using the dry process method and chisel nose radius 0.4 with a turning speed of 540 Rpm, a cutting depth of 2 mm, a feed speed of 0.226 mm/rev having a roughness value of 9.223 µm.

Abstract

Abstract The fastener is one of the most important components in the railway infrastructure that must be inspected and maintained. Installing and removing fasteners nowadays is still using manual tools like hammers and panpullers which take a long time of 12 seconds and can damage the bearings due to the rebound of the tool. And the current tool is a hydraulic pump-based e-clip fastener installation and removal tool that takes 22 seconds to remove the fastener. Therefore, a device is needed to minimize the damage on the bearing so that its use is more effective and its utility is easy because it uses a control switch that is connected to the battery and then connected to an electric jack. This tool is targeted to be able to release the fastening in a period of under 10 seconds.The process of making an electric jack-based e-clip fastener assisting tool can be carried out in several stages, each of which is the design process, the upper frame manufacturing process, the lower frame manufacturing process, the tool pusher frame manufacturing process, the tool balancer frame manufacturing process, and the completion process. The finishing process of the tool manufacturing.The function testing of the electric jack-based e-clip fastener installation and removal assisting tool at Indonesian Railways Company, Rail road unit, Madiun for road and bridge maintenance. Function testing is done twice with two different operators. The results of the tool function test, the tool can perform the process of releasing one fastener for 5 seconds and can speed up the fastening maintenance process at Indonesian Railways Company, Rail road unit, Madiun. Keyword: E-clip Mounting, Rail Maintenance, Electric.
