Abstract

The purpose of this study is to: 1) Analyse the factors affecting the damage of medium-sized excavator pumps with type 330LC-9s; and 2) analyse the impact of pump damage on medium-scale excavators with Type 330L C-9s. This type of research is qualitative with purposive sampling techniques. The population of the sample of this research was an employee in the rental workshop of excavators, with with a sample chief mechanic, expert technician, and three operators. The researchers conducted active participation observations. The results of this study are: 1) The factors causing the failure of the hydraulic pump excavators R 330LC-9s are the lack of attention of operators in operations in the field, the use of instruments that do not match their capacity, a lack of periodic service, and mechanical repairs that are not in accordance with procedures. 2) When the hydraulic pump excavators R 330LC-9s have problems, they become low-power, so noise and operational function are not at their maximum. So we need to replace spare parts, replace oil, and regularly maintain both mechanically and procedurally.

Abstract

Current technological developments are called the industrial era 4.0 and society 5.0. Currently, education in Indonesia is experiencing an increase in the quality of higher education, namely with the issuance of the Independent Learning Campus policy which was launched by the Ministry of Education and Culture in 2020. In designing the 2021 Curriculum Study Program PTM FKIP UNS has a relationship with the needs of teacher competence, the curriculum applied in SMK, and the need for expertise competence in the industrial world. In this study, researchers will examine using a tracer study method for graduates of Mechanical Engineering Education UNS and the relevance of Mechanical Engineering Education courses at Sebelas Maret University Surakarta, especially according to alumni who graduated in 2017, 2018, 2019, and 2020. Research objectives This is "To Analyze The Relevance Of Courses In PTM With The World Of Work Of Graduates". The results of the research conducted by the author are expected to be useful as input in the Mechanical Engineering Education Study Program of FKIP UNS regarding curriculum development, both regarding aspects of planning, implementing, and evaluating curriculum. The design of this research is descriptive exploratory research which aims to describe the state of a phenomenon. In this study, it is not intended to test certain hypotheses, only to describe the existence of a variable, symptom or situation. Where the variables involved in the research will be described quantitatively (according to numerical data). The research data are alumni of graduates or graduations in 2017, 2018, 2019, and 2020. The research method used is descriptive analysis data analysis method with quantitative approach to outcome-based education exploration. The results of the study stated that the level was very high, and the irrelevant ones were approximately 10 - 11 courses or 10% of the 66 - 67 courses in mechanical engineering education. It is hoped that the Mechanical Engineering Education Study Program will increase the level of relevance of courses in synchronization with the curriculum and needs in the world of work and society in the era of the industrial revolution 4.0 and society 5.0.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah dengan penerapan model pembelajaran flipped learning dapat meningkatkan prestasi belajar mahasiswa Prodi PTM FKIP UNS pada mata kuliah motor bakar. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam tiga siklus dengan setiap siklus terdiri atas perencanaan tindakan, pelaksanaan tindakan, observasi, dan refleksi. Subjek penelitian adalah mahasiswa semester II Prodi PTM FKIP UNS kelas Motor Bakar A yang berjumlah 42 orang. Teknik pengumpulan data menggunakan tes dan dokumentasi. Validitas data menggunakan validitas isi, sedangkan analisis data menggunakan analisis deskriptif komparatif. Penelitian Tindakan Kelas ini dilaksanakan pada bulan Januari sampai dengan Juli 2023. Hasil penelitian menunjukkan bahwa adanya peningkatan prestasi belajar motor bakar pada mahasiswa Prodi PTM FKIP UNS melalui penerapan model pembelajaran flipped learning. Hal ini ditunjukkan oleh persentase nilai rata-rata prestasi belajar berturut-turut pada setiap siklusnya yaitu pra siklus sebesar 9,24%, siklus I sebesar 16%, siklus II sebesar 31,52%, dan siklus III sebesar 58%. Dengan ini dapat disimpulkan bahwa model pembelajaran flipped learning dapat digunakan sebagai salah satu alternatif model pembelajaran.

Abstract

This study aims to analyze the effect of roller weight variations on the performance of the Honda Stylo 160 automatic motorcycle in 2024. The research method used is a quantitative experiment with roller weight variations of 13, 15, 17, 19, and 20 grams. Tests were carried out using a dynamometer to measure torque and power. The results showed that the roller weight variation had a significant effect on the torque and power produced. The roller weighing 13 grams produced the highest torque of 23.55 N.m and power of 13.6 HP, while the heaviest roller of 20 grams produced the highest average power of 13.06 HP. The results of this study can be concluded that the use of lighter weight rollers tends to increase torque, while heavier weight rollers tend to increase the power generated. Although there is a general increase in power with an increase in roller weight, variations in the measurement results indicate that other factors such as engine efficiency also play an important role in motorcycle performance.

Abstract

Pipa baja digunakan secara luas di dalam industri, dan proses pengerolan manual merupakan salah satu metode yang umum digunakan untuk memproduksi dan membentuk pipa-pipa tersebut sesuai pemintaan. Namun, proses pengerolan meyebabkan pipa baja terdeformasi atau disebut dengan ovalisasi. Ovalisasi pipa selama proses pengerolan manual dapat menyebabkan penurunan kekuatan struktural dan kualitas pipa. Penelitian ini bertujuan untuk menguji pengaruh pengisian pasir, hot rolling, dan kombinasi pasir dan hot rolling terhadap ovalisasi pipa baja berdiameter kecil pada proses pengerolan manual. Penelitian dilakukan menggunakan metode eksperimental, dengan empat perlakuan: pengerolan standar,  pengerolan dengan pengisian pasir, pegerolan dengan hot rolling, dan pengerolan dengan kombinasi pengisian pasir dan hot rolling. Pada tahap persiapan spesimen dilakukan pengukuran ketebalan dan panjang pipa baja hingga menghasilkan 8 spesimen uji. Kemudian, pipa-pipa tersebut diisi dengan pasir pada bagian dalamnya sesuai dengan variasi yang ditentukan. Pada tahap pengukuran, diameter spesimen setelah proses pengerolan diukur dengan akurasi menggunakan jangka sorong. Hasil pengukuran nilai ovalisasi tertinggi sebesar 0,36% terjadi pada proses pengerolan standar dengan ketebalan pipa baja 2mm. Sedangkan, nilai ovalisasi pipa baja terendah sebesar 0,05% terjadi pada proses pengerolan dengan pengisian pasir dan hot rolling. Analisis data menggunakan metode analsis deskriptif. Hasil penelitian ditemukan bahwa terdapat perbedaan nilai ovalisasi pada 4 jenis proses sehingga menghasilkan metode terbaik yaitu pengerolan dengan pengisian pasir dan hot rolling.Kata Kunci : Pipa baja, Ovalisasi, proses pengerolan
