<p>Disposal of the residual production of an industry containing hazardous and toxic materials can have a negative impact on the environment and human health. PT. X The Spinning Division is a company engaged in spinning yarn that produces hazardous waste in the production process, especially in machine maintenance. The hazardous waste produced is in the form of used TL lamps, contaminated cotton waste, used oil, and used hazardous packaging. The hazardous waste is toxic, corrosive and flammable. The purpose of this study is to compare the existing conditions of hazardous waste management with applicable regulations. The study was conducted by directly observing the existing conditions and scoring using Guttman scale. The research variables include sorting, storing, collecting, transporting, utilizing, processing and landfill hazardous waste. The results showed that the management of hazardous waste in PT. X The Spinning Division gets a score 34.3% which is categorized “Poor”.</p>

<p>Rain intensity is defined as the rainfall falls in per unit time, expressed in mm/hours. Rain determined to get the discharge flood plans in sub-districts west Bogor, Bogor. Discharge flood plan needed to take into account the drainage channel would be designed again in districts west Bogor having problems. The study aimed to determine the intensity of rainfall in west Bogor as the basic determination of the drainage channel in west Bogor. Research carried out by changing the maximum daily rainfall to rain intensity. Methods used the method Bell Tanimoto, Van Breen, and Hasper Der Weduwen which is a statistical method and produce the intensity of rain. The amount of rain obtained will be substituted into formula Talbot, Sherman, and Ishiguro, and then compared to the early rain intensity. The selection method determined based on the value of the smallest standard deviation. The result of this study showed that the method chosen to determine the intensity of rain is Van Breen Method with Talbot Formula. </p>
