“…In selecting manufacturing process, there are several attributes that need to consider, which are material to be used, number of parts required, size and shape of the product to be produced, dimensional tolerances required, geometrical complexity and the machine used. Fail to select the suitable manufacturing method such as machining process can produce incorrect required dimension and induce damage such as residual stress (Saptaji et al, 2019).…”

Shredded meat is more palatable to the taste of consumer and preparing shredded meat in a large scale requires the aid of meat shredder machine. This paper presents a detailed design procedure of a meat shredder machine developed by the VDI2221 approach. This paper also elaborates on the design of each part of the machine which includes selecting the components of the cutting and transmission system, kinematic arrangement of forces, material selection on the machine and proportion of parts to ensure the maximum strength and functionality of the machine. Further, the design of the various parts of the machine in 3D model and machine fabrication are discussed, along with the testing on the function and geometric aspects to ensure the efficiency of the machine. This study developed a meat shredder machine with 0.5 Hp electric motor and capacity of 2 kg per hour.

“…As the future works, the proposed child seat design needs to be further evaluated. Study and investigation about, e.g., its fabrication process [16], stress analysis using numerical simulation to predict its failure condition [17], as well as the vibration mode characteristics to make sure of its comfortableness [18], will be conducted.…”

Nowadays, motorcycle is considered as one of the most practical transportation mode in Indonesia. It has become a common practice that a motorcycle rider often brings a small child using a child seat while riding. However, the used child seat is usually not safe and can easily fall off from the motorcycle due to the lack of safety consideration. Moreover, it is very risky to ride a motorcycle with a small child, knowing that motorcycles are the highest contributor to road traffic accidents. For this reason, this paper proposes a primary design idea of a foldable child safety-seat that can be placed on the front part of a scooter motorcycle. This design is also completed with strength analysis to evaluate the components’ safety for children under five years old with a weight of around 50 kg. The strength calculation of the frame is done by a theoretical approach under static and dynamic loading. According to the analysis, the proposed child seat design could provide a factor of safety of more than 3.6 for static loading and 1.6 for dynamic loading. This study is expected to be used as a reference for developing a more reliable child safety- seat for motorcycle rider in Indonesia.

The increasing number of materials with variation in properties, especially hard-to-cut, leads to the need for an advanced machining method to process such material. Electric Discharge Machining (EDM) is one of the advanced machining methods widely used for hard-to-cut alloys. The EDM process uses an electrode as the conductor of electrical current to erode the metal alloys and is supported by other components. Due to EDM's high cost and high energy consumption, developing a low-cost EDM and simpler EDM setup is necessary, especially for educational purposes in laboratory activity. However, the EDM design and setup required to produce the desired “spark” have always been a challenge for researchers and manufacturers. In this research, a small-scale EDM setup was built. A solenoid actuator is used to generate simple mechanical movement. The movement is used to control the gap between the workpiece and the electrode to produce a spark. The solenoid actuator is used because of its low cost and simple mechanism. The proposed EDM setup is successfully fabricated and works appropriately by generating sparks and a hole cavity during the process. There are six cavity holes produced in mild steel workpiece during the experiments with various parameters such as current (5A, 7A, and 10A) and frequency (10 Hz and 20 Hz). The varied parameter shows that the higher current and lower frequency removed more materials. In contrast, the higher frequency produced a better quality of the cavity hole. However, the lack of flushing quality on the material debris during the process results in the formation of excess metals around the edge of the hole.
