Abstract

Pengembangan desain kontrol kinematic sangatlah penting dalam pengembangan kontrol untuk robot beroda. Hal ini sangat dibutuhkan mengingat bahwa robot beroda memiliki banyak parameter yang mampu merubah persamaan kontrol kinematiknya terutama pada kontrol kinematik untuk robot beroda dengan jenis roda omnidirectional, baik dari segi jenis roda yang digunakan hingga jumlah roda penggerak yang digunakan. Dengan berbagai macam hal yang dapat merubah persamaan kontrol kinematiknya, maka pada makalah ini dibuat sebuah persamaan kontrol kinematik yang general, yang dapat diaplikasikan untuk berbagai macam roda omnidirectional, serta berbagai jumlah roda yang digunakan. Selain itu persamaan general yang telah dibuat, diaplikasikan untuk menguji respon robot beroda dengan menggunakan 6 buah omni-wheels untuk menguji hasil respon dari persamaan general kontrol yang telah dibuat. Pengujian dilakukan dengan menggunakan simulasi program dengan menggunakan pemrograman dengan menggunakan Bahasa pemrograman python. Hasil yang didapatkan menunjukkan robot mampu bergerak sesuai dengan arah gerak target yang ditentukan, yaitu membentuk pola jalur yang linier serta mampu bergerak membentuk pola lingkaran dan pola setengah gelombang sinus. Hal ini menunjukkan bahwa kontrol kinematik yang dirancang mampu membuat robot bergerak sesuai dengan yang direncanakan. Hasil dari respon robot berupa sinyal kontrol, pola yang dibentuk serta nilai perubahan error disajikan dalam bentuk grafik. Development of the kinematics control is very important for the development of kinematics control for mobile robots. This is very necessary because mobile robots have a lot of factors that can manipulate the equation of its kinematic control, such as the type of wheels, the number of wheels, etc. With this kind of problem, it necessary to generate a general equation for the robot’s kinematic control, which in this journal we purpose the general equation for the mobile robot control, and we evaluate the outcome by applying the general equation into the 6 omnidirectional robot control. To make a valid statement, we simulate the control to understanding the control outcome by using a python program. The results of the simulation show us that the robot can move as planned, that the robot produces a linear trajectory, circular trajectory, and half sine wave trajectory. Depends on the results, it can be concluded that the proposed kinematics control equation can make the robot moves well as we planned. The results of the respons, the trajectory, and the changes in error values ​​are presented in graphical form

Abstract

Mechanical assembly requires joint mechanism involving fasteners and holes. Deformation of the holes will greatly affect the integrity of the mechanical joins. This research objective is to reveal the strain behavior of jute/polyester composite containing open hole under axial loading. It is very important to know the behavior of the strain surrounding the hole under loading. Experiments were carried out by preparing jute/polyester composites. The composites were manufactured by using a vacuum infusion method. There are two configurations of the number of laminations, i.e., 3 and 5 sheets and of hole sizes, i.e., 5 and 10mm holes. An axial load is applied to the specimen through a tensile test. Strain gauges are attached near the holes, axially and laterally. Strain in axial and lateral directions in the vicinity of a hole is recorded and presented. The research result shows that the strain gauges located parallel to the loading axis indicate a positivestrain value. On the other hand, the strain gauges located lateral to the loading axis indicate a negative value. Furthermore, the strain gauges located beside the hole in the direction parallel to the loading axis indicate the highest strain value in all types of specimens.

Abstract

Thermoplastic polyurethane round belts are widely used for conveyors in various industries, particularly in the food and beverage industry, due to their flexible and abrasion-resistant characteristics. These belts are also popular in manufacturing industries because of their ease of joint. However, a common issue arises when the conveyor belt breaks during the production process. This problem can be attributed to the lack of parameters in the belt joining process at companies. Operators do not have a standard parameter for the joining process. When there is an improper joining operation of an operator, the conveyor belt could fail earlier than the expected operation time. Therefore, the conveyor belt failure results in the loss of production time. This downtime can reach up to 15 minutes, i.e. the time required for the belt joining process. Previous studies have identified temperature and heating time as factors that influence the strength of the joint, especially when using a heating plate. Therefore, this research aims to determine the optimal parameters by varying the temperature and length of heating time in the joining process. Additionally, the research explored the impact of different cutting forms on the durability of the round belt joint. The results of this study indicate that the optimal temperature and heating time combination is 100°C for 3 seconds, resulting in a joint strength of 25,274 MPa. Furthermore, the triangular joint shape proved to be the most durable, with a record of 10,021 cycles.

Abstract

Cassava must go through several manufacturing processes before it becomes chips on the market, including the process of stirring the dough. The stirring process is an important stage in various food industries. In the stirring process, the viscosity change in the dough is influenced by various factors, including the stirring process time and speed in stirring. Research on dough viscosity is important because it is directly related to the quality of the final product. The purpose of this study is to provide recommendations to users, both in the context of using horizontal mixers and the process of making similar products. The type of research used is quantitative research based on experimental methods that aim to test a hypothesis by collecting data that can be measured using statistics, mathematics, and computing. The independent variables in this study are rotation speed (20, 40, and 80 rpm) and stirring time (5 minutes, 10 minutes, and 15 minutes). From these independent variables calculations and data analysis, the optimal setting was obtained using a rotation speed of 80 rpm and a stirring time of 15 minutes with a dough viscosity of 1411.12 PaS. The rotation speed of 80 rpm has more even data or more consistent data compared to the rotation speed values of 20 rpm and 40 rpm.
