In various types of statistical analysis, the Weibull distribution is an important continuous probability distribution. One crucial aspect of studying this distribution is estimating its parameters. The maximum likelihood method is the approach used for the two-parameter Weibull distribution. This method aims to determine the parameter values by maximizing the likelihood function based on the available data. The advantages of the maximum likelihood method lie in its properties, such as consistency, efficiency, and asymptotic normality. Since the form of the likelihood function in the Weibull distribution is quite complex and cannot be solved analytically, numerical solutions are required. One approach used is the Newton-Raphson method, which serves to approximate the parameter values or find the optimal solution.

This study examines the Material Requirement Planning (MRP) method in planning the production of Dewi Passion Fruit syrup. Through a literature study approach, collecting articles or journals related to production planning, determining order size and MRP. The results showed that the results of forecasting the demand for passion fruit syrup were 87,751 liters with passion fruit raw materials of 175,502 kg and sugar of 87,751kg. As well as based on the Material Requirement Planning (MRP) method and lot sizing techniques which include Silver Meal Algorithm and Wagner Within Algorithm, the one used in this study is Silver Meal Algorithm because it has a smaller total order cost and storage cost than Wagner Within Algorithm.

The aim of this research is to determine the impact of tornado victims in Ranca Ekek, Sumedang Regency and Cicalengka, Bandung Regency. Empowerment of tornado victims. The research method uses a qualitative approach that describes events in locations affected by tornadoes. Data collection techniques were interviews with several victims, RW administrators and RW administrators, observation at the location, photographing the condition of the places and houses of residents affected by the tornado. Literacy studies related to the tornado phenomenon include books and the internet. Conclusion The impact that occurred on the victims resulted in damage to people's houses and sales stalls on the side of the road so that they had no shelter to take shelter in and lost a place to sell. Empowerment of residents affected by tornadoes, consisting of 5 affected sub-districts, namely Rancaekek, Cicalengka and Cileunyi sub-districts, Bandung Regency, as well as Mangunraja and Jatinangor sub-districts, Sumedang Regency. Erected tents for around 121 residents, provided treatment to around 113 residents with minor injuries and 10 moderate injuries. In the future, the Regent of Sumedang and the Regent of Bandung will allocate assistance to the community so they can rebuild houses and kiosks for selling.
