This article discusses the concept of forced vibration in the design of vibratory ball mill machine. The eccentric system produces the translational motion of steel balls and powder tubes. The presence of the SDOF spring-mass system increases the eccentric force. In the initial position, the tube containing the steel ball and powder moves upward due to the eccentric thrust of the shaft until it touches the upper spring. As the cylindrical tube pushes against the top spring, the spring exerts a force that pushes the tube in the opposite direction. The impact and attrition causes the powder to b

This research aims to analyze the application of the Cooperation Principle in the performing arts of stand-up comedy in Indonesia. The Cooperative Principle, developed by philosopher and linguist H.P. Grice, is the basis for effective communication and mutual understanding. In the context of stand-up comedy, artists use this principle to create humor that can be accepted by the audience. This research method uses a sociopragmatic approach, focusing on the relationship between language and social context. Data was collected from standup comedy performances by several leading comics in Indonesia

The RAG well is an oil well that has been workover by moving layer workover at a depth of 3788.1 - 3820.1 ft MD in TAF tight sandstone formation with a directional well configuration located in the Cessna field of the Northern West Java basin. This well has a shaly sandstone reservoir with silt rock intrusions with a permeability value of 10 mD and a porosity of 15%. This low permeability of the formation may affect the daily barrel fluid per day produced from the well, this is the main reason why it is necessary to plan stimulation in the form of hydraulic fracturing in RAG well with the hope

Data security is one of the disciplines that focuses on building data structures. Data encryption techniques are one of the data security practices used in the manipulation of information confidentiality. This research aims to modify data encryption by applying magic graphs to the randomness of data encryption with Fibonacci patterns. The data encryption algorithm with the magic of the Fibonacci graph is performed with the modification of the weight on the G (E,V). The result of this study is the encrypting of the data with the pattern of the graph of the interconnected G (E,V) weighting resul

Within the landscape of green supplier selection research, numerous studies have been conducted; however, only a select few have systematically integrated decision-maker preferences into their investigations, representing a potential gap in the existing literature. The objective this research to solve the supplier selection that involving the environmental consideration, decision maker preferences, and uncertainty availability of resources in the palm oil industry. The criteria for the selection of fresh fruit bunches supplier include price, quality, delivery time, carbon emissions and decisio
