Abstract

Penelitian ini dilakukan untuk memberikan penjelasan tentang studi eksperimental pengaruh variasi beban dan variasi aliran terhadap efek water hammer. Dimana efek ini akan mempengaruhi tekanan air yang akan dihasilkan jika setelah pembebanan dan perubahan bukaan valve yang diberikan akan menghasilkan efek water hammer yang lebih baik atau cenderung lebih buruk bila tidak memiliki kedua efek tersebut. Penelitian ini dilakukan dengan melakukan studi eksperimental yang bertujuan untuk mengetahui tekanan yang terjadi pada saat air mengalir dan kemudian ditutup secara tiba-tiba oleh katup pembuangan yang dihubungkan dengan aliran pipa dengan diameter 1,5 inci setelah beban dan variasi bukaan katup. Pada uji efek water hammer dengan sistem pompa water hammer hidrolik ini dimungkinkan untuk mengubah bukaan katup pemasukan air dengan perubahan beban katup yang diberikan untuk menentukan tekanan water hammer maksimum 378334,64 Pa setelah menerima katup bukaan 80 derajat dan tambahan beban 250 gr, dan efek water hammer terkecil dengan nilai 321376,44 Pa pada bukaan katup 50 derajat dan beban 150 gr. Saat menginvestigasi pompa hydraulic ram ini, dapat disimpulkan bahwa ukuran bukaan valve atau jumlah air yang masuk dan besarnya beban pada discharge valve yang akan mempengaruhi tekanan akan meningkat.

Abstract

The Shredded fish is produced by machines automatically, which can facilitate the production process. Previously the process was done conventionally in one production run. This problem prompted researchers to create a machine by combining three tool systems to become a shredded fish processing machine, including a system for separating meat and fish bones, a cooking furnace system, and a shredded dryer/spinner system that can be controlled electrically in the production process, in addition to the shredded produced more cleanly and efficiently in one production process. This machine utilizes the power of an electric motor of ¾ Hp, which is the driving force for the meat separator machine with a rotation speed of 2840 rpm and a production capacity of 30 Kg/hour.

Abstract

The bread machine is also a leverage to increase production capacity and production quality. In contrast to manual bread production, which requires a lot of effort and time, a bread machine makes everything more efficient. The bread machine's output is better than manual production's. Besides that, the hygiene of the bread produced is guaranteed. The device is sterile and safe because all materials are protected with stainless plates, a mixer motor flame that can be adjusted according to needs, and an automatic oven according to requirements. The tray uses hygienic, not harmful to health, and environmentally friendly and pollution-free materials. The level of safety in use is higher because it has appropriate dimensions. The technique for operating a semi-automatic bread-making machine with a production capacity of 4 kg requires 45 minutes with an oven process temperature of 100 ºC to 150 ºC.

Abstract

The food drying process is an innovative method to change the process of reducing the water content of fresh food products of plant origin to slow down the emergence and growth of unwanted microorganisms. This heating system has four heating elements, where the heating elements used have a power of 1200W because each heating element has a power of 300W. During the drying process, it is known that the average air temperature in the drying room is higher when using solar energy compared to a heating system. The average temperature measurement during the day is 38°C. The measurement results tend to be constant, with an average of 34°C for 7 hours using the heating system. The battery voltage shows an increase every hour. At 08:30 am the battery voltage was 12.3V, and until 16.00 the voltage was 13.57V. This dryer is sourced from solar energy because using solar for drying requires a longer time, namely 8 hours (08.30-16.00), compared to using a heating system for 7 hours.

Abstract

Injection molding has become a significant manufacturing technique in producing complex polymer components. Its molding efficiency depends on various process and machine parameters, which determine the quality of the final product in terms of various output responses. It is important to state that proper optimization of different input parameters is essential to achieve the desired quality index. This article presents a review of various techniques used so far to optimize various injection molding parameters, along with their advantages and limitations. It is found in the review that a brilliant technique that can be operated without human intervention has not been developed. The design of the injection machine uses a small scale between 75 gr to 150 gr with a heating variation ranging from 200 0C to 250 0C. When testing the tool, it showed that to achieve the optimal final result of a product, it takes 228 seconds at a hot temperature of 200 0C; if the temperature is increased to 225 0C, it takes 217 seconds, and if it is increased to 250 0C, it takes a shorter time of 208 seconds.
