Abstract

Mechanical Engineering Education study program is a study program that produces professional staff in the field of teaching and engineering who have competence in carrying out teaching processes, workshops, manufacturing processes, manufacturing drawing designs, etc. One of the courses in PTM is Computer Aided Design 1. This course is a compulsory subject that must be taken by PTM students in semester 4. The problem that occurs in this research is the implementation of learning in Computer Aided Design 1 courses in study programs The Mechanical Engineering Education of the Sebelas Maret University FKIP has not been maximized, so it is not known the degree of suitability between the implementation of the learning program and the semester learning design and the resulting output. Therefore, appropriate learning tools are needed in the learning process for CAD 2 courses. Testing the feasibility of these learning tools involves 3 parties, namely material experts, media experts, and users. From the assessment of material experts, it was obtained that the percentage of eligibility averaged 81,75% and was included in the "very feasible" category. From the assessment of media experts, it was obtained that the average percentage of eligibility was 90,55% and was included in the "very feasible" category. The trial process was attended by PTM students who were taking CAD 2 courses. From the user response data of 70 respondents, it was obtained that the average eligibility percentage was 91,24% and was included in the "very feasible" category. The conclusion is that the results of the reconstruction of the Computer Aided Design 1 course are very feasible and suitable for use in the learning process.

Abstract

This study aims to analyze the effect of variations in the number of blades and the use of end plates on the cut in speed of Helical Savonius wind turbine. The method used in this research is the experimental method. The variables used in this study are variations in wind speed from 1 to 5 m/s with intervals of 0.5 m/s. Variations in the number of blades are 2,3, and 4 blades. Variations in the use of end plates and without end plates. The results of this study was found that variations in the number of blades and the use of end plates affect the cut in speed of helical Savonius wind turbine. The fewer the number of turbine blades, the better the turbine's cut in speed will be. 2 blade’s Helical Savonius wind turbine with end plate is turbine variation that is able to produce best cut in speed of 1.97 m/s, compared to other variations.

Abstract

The need for energy progressively increase, meanwhile fossil fuel reserves gradually decrease since it is nonrenewable resourses. Coffee grounds and polypropylene plastic waste can be used as alternative fuels. One of the ways to use coffee grounds and plastic waste as fuel is through the pyrolysis process. Pyrolysis is a chemical decomposition process of a material thermally in the absence of oxygen which converts RDF-4 into a liquid smoke product in the form of oil. The purpose of this study was to determine the effect of the comparison of the composition of the mixture of coffee grounds and polypropylene plastic waste on the quantity of pyrolysis oil. This study uses an experimental method with quantitative descriptive analysis techniques. This research was carried out by means of a pyrolysis process on RDF-4 a mixture of coffee grounds biomass waste and polypropylene plastic waste with various composition ratios of 0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%. The pyrolysis oil is then filtered, for later testing the quantity. The test shows that there is an effect of variations in the ratio of the composition of the biomass mixture to the quantity of pyrolysis oil. RDF-4 from coffee grounds waste mixed with polypropyelene plastic waste produces a quantity that tends to decrease as the ratio of coffee grounds composition decreases. RDF-4 which is not mixed with coffee grounds or has a composition ratio of coffee grounds less than the composition ratio of polypropylene plastic waste produces pyrolysis oil with more quantity and quality that tends to be better than the ratio of other RDF-4 compositions. The quantity of pyrolysis oil produced ranged from 219.33 ml to. 1026.67 ml. RDF-4 from 100% polypropylene plastic waste produces pyrolysis oil with the highest quantity of 1026.67 ml with the highest pyrolysis temperature achieved 391°C at T1, 345.5 °C at T2, and 367.75 °C at T3.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi rekomendasi turbin angin yang sesuai untuk pengukuran berdasarkan potensi angin di Kabupaten Jaten. Penelitian ini menggunakan metode eksperimen. Sumber data untuk penelitian ini meliputi pengukuran kecepatan dan arah angin yang diperoleh menggunakan mikrokontroler berbasis IoT. Purposive sampling digunakan untuk mengumpulkan sampel. Alat yang digunakan untuk pengambilan data terdiri dari anemometer untuk mengukur kecepatan angin dan wind vane untuk menentukan arah angin. Data dianalisis secara deskriptif dan kuantitatif. Hasil kajian menunjukkan kecepatan angin rata-rata tertinggi teramati pada ketinggian 10 meter Di Kabupaten Jaten kecepatan angin rata-rata 0,47 m/s, dengan kecepatan tertinggi 3,38 m/s. Arah angin dominan bertiup dari Tenggara ke Barat. Potensi angin di daerah ini tidak cukup tinggi untuk dimanfaatkan secara efektif sebagai sumber energi angin yang signifikan karena besarnya yang rendah. Dalam konteks Kabupaten Jaten, kincir angin Savonius vertikal direkomendasikan untuk memanfaatkan kecepatan angin rendah. Jenis turbin Savonius yang dapat digunakan seperti turbin Savonius tipe Helical 2 bilah dengan end plate memiliki kecepatan potong 1,906 m/s dan turbin Savonius tipe S 2 bilah dengan penambahan 4 sirip memiliki kecepatan potong 1,8 m/s.
