Abstract

The phenomenon of dishonesty occurs a lot in the academic field, one of which is plagiarism and cheating which are often encountered in universities in the process of learning and research. Academic dishonesty at the tertiary level in Timor-Leste is considered to affect the integrity of graduates when entering the workforce. The purpose of this study is to analyze indicators of academic dishonesty, causes of academic dishonesty, and appropriate solutions to overcome academic dishonesty of university students in Timor-Leste class of 2020-2022.           This research is a positivistic quantitative, descriptive research. The research was conducted using a Google form. The subjects of the study were 59 university students in the Timor-Leste class of 2020-2022. The data collection technique is by using questionnaire methods and questionnaire instruments. Validity and reliability of data using the help of data processing software. Data analysis uses descriptive statistical analysis technique. The results showed that the indicators of academic dishonesty of Higher Education Students in the Timor-Leste class of 2020-2022 were Working together with friends during the exam, Allowed other students to see answers during quizzes or exams, Asking exam questions to other students who had done exams before, Seeing cases of cheating in class and not reporting it to the supervisor. The cause of academic dishonesty is that the questions given are very difficult and students consider working together during exams a form of solidarity. The solution to overcome academic dishonesty is that there is a reprimand when committing academic cheating, supervisors are firm in addressing academic dishonesty, and there are severe penalties when caught cheating.

Abstract

Technology has created numerous benefits in various aspects of life, including education. Teachers and students should integrate technology into their learning plans to ensure effective teaching and learning. The use of technology in education can inspire students to pursue new interests and motivate them to engage in learning activities that enhance their perspectives. The role of an instructor in a student's education is crucial. Self-directed learning (SDL) is an instructional process that requires students to identify their own learning needs, provide resources, and practice learning techniques. By using the right methods and situations in teaching, students can develop their own skills and enhance their learning experience. This study aims to improve the effectiveness of e-module practical on the otomotif kelistrikan in the Mesin Technical Education program.The study on the development of an e-module for otomological pedagogy found that the validity of the e-module met good results with validity scores of 84.4% (very feasible) for material, 85% (very feasible) for media, 75% (feasible) for language, and 83,3% very (feasible) for data from student responses. Critics and respondents also deemed that improvements are needed for the e-module. The results were based on feedback from the committee of otomologists who provided some suggestions about the electronic pedagogical pedagogy module in terms of quality and safety, indicating that improvements are still needed for this module. The e-module will be distributed through the Mesin Technical Education Program at the University of Surakarta.Keywords: development, e-modules, self directed learning

Abstract

In the current era, automatic motorbikes are the most popular motorbikes and are most widely used for everyday purposes. The motorcycle population always increases by around 5 million units every year. Of this amount, around 70% are motorbikes of the matic type, aka scooters. One trick that is usually used by automatic motorbike lovers to upgrade the characteristics of their automatic motorbike is to replace a part called the CVT roller. The aims of this study were: (1) To find out the effect on fuel consumption produced by a 110cc automatic motorcycle using variations in roller weight. (2) Knowing the effect on fuel consumption produced by 110cc automatic motorbikes using variations of engine speed. (3) Knowing the effect of using roller weight variations at RPM variations on fuel consumption on 110cc automatic motorcycles. The research method used is experimental. The research data was obtained by measuring the Honda BeAT New 2018 motorcycle sample. The independent variable is roller weight Variation and Variation of engine rotation. The dependent variable is fuel consumption. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) The use of variations roller weight 10, 12, and 14 grams have an effect on fuel consumption. The use of a roller that is heavier or lighter than standard (12 grams) has the effect of producing a more different fuel consumption. (2) Variations in engine speed (3500, 5000 and 6500 RPM) have an influence on fuel consumption. Each increase in engine speed, the fuel consumption will also increase. This happens because the higher the engine speed, the higher the amount of fuel burned in the combustion chamber. (3) Has the effect of fuel consumption on the use of roller weight variations and variations of engine speed. This effect lies in the average fuel consumption using less standard rollers when compared to using lighter or heavier rollers. Overall, if you take the best, then the right choice is a standard 12 grams roller, because it has the lowest average fuel consumption value.

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

Tujuan dari penelitian ini adalah memperoleh tahapan kerja yang memiliki resiko kecelakaan kerja paling besar di bengkel body repair. Peneliti membatasi penelitian ini dengan melakukan penelitian di dua tempat yaitu bengkel Mitsubishi bodi & cat sebagai bengkel authorized dan bengkel Auto 168 sebagai bengkel non authorized. Data pada penelitian ini diambil dengan cara observasi dan wawancara. Peneliti akan menganalisis data dengan menggunakan metode Failure Mode And Effect Analysis (FMEA). Peneliti akan memperoleh nilai risk priority number (RPN) melalui tiga parameter yaitu, severity (S), occurrence (O), dan detectability (D) dari tiap-tiap tahapan kerja. Dari penelitian ini, akan diperoleh peringkat tahapan kerja dengan resiko kecelakaan kerja terbesar hingga terkecil yang akhirnya digunakan sebagai dasar dalam menggambarkan potensi kecelakaan kerja dan faktor penyebabnya, serta memberikan rekomendasi cara meminimalisir kecelakaan kerja.
