This study aims to (1) determine the effect of voltage variations on the power ignition box on the torque and power of the Honda Scoopy motorcycle in 2017. (2) determine the effect of variations in the voltage on the power ignition box on the fuel consumption of the Honda Scoopy motorcycle in 2017. (3) Knowing the effect of voltage variations on the power ignition box on exhaust emissions of the Honda Scoopy motorcycle in 2017. (4) Knowing the best voltage variations on the power ignition box are on power torque, fuel consumption, and exhaust emissions of the 2017 Honda Scoopy. Engine performance, including power torque, fuel consumption, and vehicle exhaust emissions, will be obtained by the maximum vehicle engine if the combustion system works optimally. One way to maximize the combustion system is using a power ignition box. The research method used is experimental. The research data was obtained using a sample of Honda Scoopy motorcycles in 2017. The independent variable used a power ignition box with voltage variations of 14.4 V, 14.7 V, 15.0 V, 15.3 V, 15.6 V, and 15 .9 V. The dependent variable is the power torque using a Dynamometer, fuel consumption using stationary test and road test on predetermined roads, and exhaust emissions using a Gas Analyzer. The results of this study are: (1) The maximum torque is obtained at a voltage variation of 15.6 V of 9.57 N.m, an increase of 8.5% from the standard state. The maximum power is obtained at the 15.6 V voltage variation of 6.63 HP, up to 8.5% from the standard state. (2) The maximum fuel consumption for the stationary test was obtained at a voltage variation of 14.7 V of 4.25 ml/min, decreased by 0.18 ml/min. The increase in average fuel consumption is at a value of 4.55 ml/min. The maximum fuel consumption for the road test was found at a voltage variation of 14.7 V of 30 m/ml increasing to 15 m from the standard state. The average increase in fuel consumption was 24.93 m/ml from standard conditions. (3) The maximum CO (carbon monoxide) of 0.3% at a voltage variation of 14.4 V, down 0.11% from standard conditions. The maximum HC (hydro carbon) is 16.00 ppm at a voltage variation of 15.0 V, down 15.33 ppm from standard conditions. Maximum CO2 (carbon dioxide) is 2.0% at a voltage variation of 15.9 V, down 0.10% from standard conditions. The maximum O2 (oxygen) is 9.25% at a voltage variation of 15.6 V, down 3.23% from standard conditions. The best configuration for the Box Power Ignition is at a voltage of 15.3 V.Keywords: Honda Scoopy, Box Power Ignition, Torque and Power, Fuel Consumption, Exhaust Emissions.

Abstract

Academic dishonesty is a deliberate violation of academic rules for personal gain. Academic dishonesty can reduce the reputation of students and universities, as well as dishonest behavior in the world of work, so research is needed regarding engineering students' perceptions of academic dishonesty. This study aims to determine perceptions, experiences, reasons why engineering students commit academic dishonesty, and to determine the influence between perceptions and experiences of witnessing acts of academic dishonesty. The population used in this study were S1 students from the UNS Faculty of Engineering and the samples taken were 97 respondents. The results of the study show that engineering students' perceptions of academic dishonesty are that students know that academic dishonesty is important, can have an impact on damaging moral character, including actions that violate social and religious norms, so that it becomes the student's responsibility, and must be responsible for caring for the integrity of other students. . The experience of engineering students with academic dishonesty is that students have committed dishonesty but support existing policies, often use unauthorized material during exams, work on papers or articles without including references, and ask for help from seniors who have taken exams but rarely submit assignments properly. pay someone else to complete it and rarely miss out on group assignments. Academic dishonesty policies already exist but sanctions and supervision need to be tightened to reduce academic dishonesty. The reason engineering students commit academic dishonesty is because they don't get sanctioned or punished, the attitude of the lecturer, many friends who do this, will make grades better, difficulty working on questions, easy internet access and fear of failure and lack of study time. Most of the respondents committed academic dishonesty due to internal factors. There is a positive and significant influence between perception and experience of witnessing techniques on the experience of committing academic dishonesty. So that when the perception and experience of witnessing gets higher, they will not commit academic dishonesty.

Abstract

The demand for fuel oil is increasing day by day, resulting in the depletion of oil and gas reserves in Indonesia. Rice husk waste biomass and low-density polyethylene plastic are wastes that can be utilized as alternative fuel sources by pyrolysis method. Pyrolysis is the process of burning organic and synthetic materials in conditions of little or no oxygen by utilizing heat from high temperature combustion. Pyrolysis method processing requires a heater to burn the material during the process. Efforts that can be made are the use of biomass stoves as the right solution because of the availability of abundant and cheap raw materials, biomass stoves can also provide solutions to reduce the impact of environmental pollution smoke. The purpose of this study was to determine the temperature produced by the biomass stove and the effect of the comparison of the composition of the biomass mixture of rice husk waste and low density polyethylene plastic waste on the quantity of pyrolysis oil. This research uses experimental method with quantitative descriptive analysis technique. This research was conducted by pyrolyzing a mixture of rice husk biomass waste and low density polyethylene plastic waste with variations in composition ratio of 0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%. The pyrolyzed oil was then filtered and tested for quantity. The test results show that the biomass stove can be used as a heater in a pyrolysis device with a capacity of 4 kg of coconut shell briquettes. The use of coconut shell briquettes as fuel has the advantage of being able to produce higher heat and last longer than charcoal. The biomass stove can produce the highest pyrolysis temperature reaching 665.5°C at the bottom, 541°C in the middle, and 430.3°C at the top. There is an effect of variation in the composition of the mixture of rice husk waste and low-density polyethylene plastic waste on the quantity of pyrolysis oil. The composition of more rice husk waste compared to low density polyethylene plastic waste produces less quantity of pyrolysis oil, while the comparison of the composition of more low density polyethylene plastic waste compared to rice husk waste produces pyrolysis oil with more quantity. This can be seen from the quantity of pyrolysis oil produced ranging from 265 ml to 853.3 ml.

Abstract

Renewable energy technologies are currently being developed, one of which is wind turbines. There are two types of wind turbines, namely the vertical axis and the horizontal axis. One of the horizontal wind turbines is the helical savonius. The development of this technology can help the development of renewable energy. The Mechanical Engineering Education study program is testing wind turbines to help students understand wind turbine technology. Through this research a practicum module will be created to assist students in carrying out wind turbine practicum.This electronic module validates the material and media. The results of the material validation stated the suitability of the material in accordance with the material on wind turbines that had been taught in wind turbine courses. The results of the media validation state that the design is attractive and easy to read so that students can understand the electronic module.
