Abstract

Pemotongan keju blok yang dilakukan secara manual dengan menggunakan pisau membuat proses pemotongan menjadi lama sehingga operator kesulitan dalam mencapai target yang telah ditentukan. Mesin pemotong keju merupakan mesin dengan sistem pneumatik yaitu memanfaatkan tenaga angin sebagai penggerak untuk mendorong keju. Tujuan penelitian ini untuk memberikan gambaran rancangan mesin pemotong keju agar proses pemotongan keju terutama dalam bidang insutri menjadi lebih cepat. Pengambilan data pada penelitian ini yaitu meliputi observasi secara langsung, wawancara dan studi literatur. Hasil penelitian yang diperoleh adalah dari segi kualitas serta kuantitasnya. Mesin pemotong keju dengan sistem pneumatik ini dilihat dari segi kualitasnya hasil potongan keju menjadi seragam dibandingkan jika memotong secara manual. Sedangkan jika dilihat dari segi kuantitasnya mesin ini mampu menghasilkan 31,65 blok dibandingkan dengan pemotongan manual yang hanya 6,4 blok keju. Dari hasil tersebut dapat disimpulkan bahwa dengan mesin pemotong keju ini proses pemotongan menjadi lebih cepat dengan ukuran yang seragam.

Abstract

A trolley fabrication company that implements a make-to-order system in the production process. Of the several types of trolley models, one of them is the mesh model trolley where one of the components uses a clamp plate. Where the clamp plate functions to bind one component to another so that the mesh trolley can function more effectively. It is made using a press machine with Punch and Dies. In making clamping, the process used is shearing and piercing. The selection of dies will be based on the practicality of the product manufacturing process, as well as the relatively cheaper cost of making dies. In the manufacturing process of this product, a single compound die will be used. The shearing and piercing processes are only one process, so it can save a lot of time and costs. For this die planning process, the work includes the amount of cutting force, the required machine capacity, clearance, punch dimensions, dies dimensions and supporting tools used. The material used to make clamping is SPCC SD with a thickness of 3 mm. The machine capacity used is 25 tons. The cutting operational force for the shearing process is 62361.6 N, for the piercing hole process is 20267.5 N. So by using a separately made punch contour design, it can make it easier during the maintenanceprocess and the production process can be carried out in bulk.

Abstract

Solar energy is one of the most promising and inexhaustible sources of renewable energy. Solar panels, as the primary devices for converting solar energy into electrical energy, have been widely utilized. However, issues related to the efficiency of these panels remain. Panels installed in a fixed position can only optimally absorb sunlight at a specific time of day, whereas the sun’s position shifts dynamically from east to west throughout the day. This study discusses an effective and efficient solar tracker mechanism that enables the panel to follow the sun’s movement throughout the day. The results of the study indicate that the design of a single axis solar tracker mechanism (east to west) with a target rotation of 180° over 12 hours or 15° per hourincrements requires a DC motor with a speed of 1400 rpm, an internal gearbox with a ratio of 80:1, and an external gear with a ratio of 12:1, resulting in a total gear ratio of 960:1. Consequently, the final output speed of the motor is reduced to 1458 rpm, meaning the motor only needs to be active for approximately 10.26 seconds to rotate the panel by 15° per hour.

Abstract

The development of electric vehicles is becoming a trend in the development of global automotive, this is supported by the development of energy storage technology and energy conversion devices that allow for an increase in overall energy efficiency in current electric motor vehicles. Therefore, the study aims to determine the effect of welding strength with 1 mm thick ST40 sphc steel plate material, this material must be tested first for the manufacture of battery casing, one of which is important in making this battery casing by welding, the welding used is SMAW (Shielded Metal Arc Welding), with current variations of 20A, 30A, and 40A. Therefore, it aims to find out which current is good in the welding process itself. With data processing of the two-way ANOVA method. The process of testing the effect of current variations on visual conditions using 40A is better than the others, Tensile Strength ????ℎ????????????????????>???????????????????????? 12.71>5.143, Yield Strength ????ℎ????????????????????>???????????????????????? 7.24>5.143, and elongation ????ℎ????????????????????<???????????????????????? 3.40<5.143.
