Abstract

Belt conveyor is an intensive material transfer machine used in every branch of industry such as the casting industry, paper industry, food industry, coal mining industry and, so on. Most industries use the belt conveyor itself because belt conveyors can operate efficiently, practically, also economically. Transported materials can be bulk load or unit load, as well as easy maintenance and operation. Therefore it is necessary to design a conveyor belt according to the type of material to be transported. The design carried out is the design or engineering of conveyor belts, calculation of conveyor belt capacity, calculation of motor power, machine element analysis, and frame material used. The results obtained include making a belt conveyor unit, load design, designing a belt conveyor unit load with a carrying capacity (Qt) 5.2 ton per hour, loading weight - belt conveyor length (Wm) 8.66 kg/m, belt load maximum (Fmax) 165.65 kg, motor power 0.5 HP. The belt used standard type PVC food heat resistance up to 90°C. The frame belt conveyor uses SS 304 standard food material.

Abstract.The rapid development of science and technology in the world so that it can bring up ideas, one of which is to make an animal feed printing machine with the Two In One concept to make it more efficient, especially for micro-scale chicken farm entrepreneurs. In making this animal feed printing machine, it cannot be separated from the power of the driving motor, because the power of this motor determines whether or not a movement mechanism occurs in this machine. the force that occurs in this animal feed printing machine, the transmission used must also have its own advantages. This feed printing machine uses an AC induction motor with 1 phase induction, 1 HP power, and a rotation speed of 1490 RPM. The transmission used in this machine has two types of transmission, namely the chain sprocket with a sprocket diameter of 101.6 mm in the gearbox, the diameter of the sprocket on the printer is 100 mm while the diameter of the pully used in the printer is 101.6 mm in diameter and 304.8 mm in the printer. mixer. Loading affects the speed and power that occurs in this machine, when the engine is loaded, the power that occurs is greater and when the engine is loaded the engine rotation speed decreases it causes the load and speed values ​​to be inversely proportional.

Abstract

Electrical discharge machining (EDM) is one method of manufacturing precise parts with materials that are difficult to cut. EDM has wide applications in the automotive and aerospace industries. The process of electrical erosion consists of the removal of material from the workpiece due to an electric discharge that occurs between the work electrode and the workpiece surface. The electrodes and the workpiece are connected to an electric charge generator.This thesis presents the results of experimental research on electrical discharge machining (EDM), in which the workpiece material is SPHC plate and copper electrodes. The method used in this experiment is the Taguchi method to determine the optimal parameters by varying the current parameters (7A, 12A and 15A), spark on time (210 s, 340 s and 400 s), Gap (50V, 45V and 40V). Process performance measured in this case is the Material Removal Rate and Surface Rougness. The results of the experiment using the Taguchi method showed that the largest optimal MRR was 82.10 mm3/min at current=15 A; Spark on time= 340 s; gap= 50 volts. For the smallest optimal value of SR is 26.00 m at 7 A current; Spark on time= 210 s; gap= 45 volts.

Abstract

Sling bearings are one of the important components in the cable car transportation system. These bearings function to support the weight of the cable car and reduce friction between the train and the rail/sling so that the train can move smoothly and safely. To produce quality sling bearings, a precise and accurate machining process is required. The manufacturing process of ropeway sling bearings goes through a machining process, where raw materials that are usually metals or metal alloys will be cut, shaped, and polished to form the desired bearing shape. Fixture machining is one of the most commonly used techniques in the machining process, where the workpiece is clamped or fastened to a specially designed fixture so that the workpiece remains stable during the machining process. The purpose of this engineering is to produce a fixture design for sling bearing components with increased quantity and quality of products on CNC machines by validating the design through simulation. In this study, tests were conducted using a conventional machining fixture and a machining fixture equipped with a pneumatic system. The test results show that the machining fixture equipped with a pneumatic system is able to increase the production speed and efficiency of cable car sling bearings by up to 20% compared to the conventional fixture. This research makes an important contribution to the cable car sling bearing manufacturing industry in improving production efficiency and final product quality. In addition, this research can also be a reference for further research on the optimization of the cable car sling bearing production process.

Abstract

PT.XYZ mengalami ketidak balancenya loding vs capacity pada produksi line assy caliper 2 dengan selisi produksi 13 pcs/jam selisi cycle time current terhadap take time adalah sebesar 2.1 detik data ini sesuai dengan laporan produksi line assy caliper 2 , Gap ini terjadi akibat proses clamping griper mesih dilakukan secara manual akibatnya banyak waktu Muda ( sia-sia ) pada proses tersebut. Sering terjadi part terjatuh , part susah dipasang dan dilepaskan sehingga berakibat proses jadi delay selama 2,1 detik laporan ini terlihat pada grafik monitoring problem line produksi assy caliper 2 . Dengan konsep melakukan penelitian dilapangan produksi langsung kemudian menganalisa kareteristik proses produksi diharapkan problem yang terjadi dapat dicarikan solusi untuk menghilangkan waktu MUDA ( Sia-sia ). Dari hasil penelitian ini membuktikan bahwa memodifikasi jig & fixture dengan pendekatan prinsip 6 Degree Of Freedom dapat menghilangkan gap produksi pada line assy calip er 2 sebesar 2,1 dtk atau 13 pcs /jam dengan cara merubah proses produksi manual menjadi Otomasi dan membuat jig & fixture pencekam benda kerja yang peneliti sebut Chuki-chuki Otomation. Hasilnya setelah dirubah system manual ke otomasi dengan menggunakan Chuki-Chuki pencekam proses loading dan unloading caliper di line assy caliper dapat dihilangkan sehinga bisa mengurangi waktu 1,5 dtk waktu loading dan unloading

Abstract

A potential solution to mitigate exhaust emissions and air pollution is converting conventional motorcycles into electric ones. This study carried out the conversion of a gasoline-powered motorcycle to an electric motorcycle and analyzed changes in its dynamic characteristics through measurements of the center of gravity, suspension load distribution, and two-degree-of-freedom vibration response. The methodology involved determining the motorcycle’s center of gravity before and after conversion using the moment-of-force approach and conducting vibration analysis with a two-degree-of-freedom undamped model. Tests were performed in unloaded and loaded conditions with a 70 kg passenger to evaluate the effect of additional mass on suspension performance. Before conversion, the motorcycle’s center of gravity was located at x = 526 mm and y = 147 mm, shifting to x = 577 mm and y = 133 mm after conversion. With a passenger, the center of gravity moved from x = 754 mm and y = 704 mm to x = 762 mm and y = 687 mm after conversion. The total load decreased from 267 kg (74.8 kg front and 192.2 kg rear) to 239.6 kg (66.9 kg front and 172.7 kg rear). The vibration analysis revealed that the main natural frequency slightly increased from ω₁ = 19.507 rad/s (≈3.10 cps) to ω₁ = 19.654 rad/s (≈3.12 cps), while the secondary frequency remained stable at ω₂ = 4.52 rad/s (≈0.71 cps). The amplitude ratio changed marginally from (A/B) = 6.028 m/rad to 6.088 m/rad. Overall, the conversion does not induce significant additional vibration, indicating that the structural dynamics remain stable. However, fine-tuning of battery placement and suspension stiffness is recommended to optimize stability and ride comfort.
