Natural disasters due to excessive rainfall often cause huge losses in the form of impacts including casualties and economic losses. To minimize casualties, disaster mitigation is needed, while financing for disasters (emergency response) and financing after disasters (rehabilitation and reconstruction) can be carried out with insurance. This paper aims to determine mitigation efforts and insurance premiums for natural disasters. The method as a mitigation effort is studied based on several meth...

The influence of social media in disseminating information, especially during the COVID-19 pandemic, can be observed with time interval, so that the probability of number of tweets discussed by netizens on social media can be observed. The nonhomogeneous Poisson process (NHPP) is a Poisson process dependent on time parameters and the exponential distribution having unequal parameter values and, independently of each other. The probability of no occurrence an event in the initial state is one and...

This paper discusses the formulation of a risk model for paddy agricultural insurance in Indonesia. Indonesia as an agricultural country with a tropical climate, where the sun shines throughout its time, farmers can plant crops throughout the season. In particular, rice farming is currently an inseparable part of most agrarian societies in Indonesia, especially in West Java. However, changes in air temperature, weather and annual rainfall, which sometimes changes uncertainly, cause changes in cr...

Garbage is one of the problems that often occur in the community, especially in the disposal and handling of its existence. The Integrative KKNM-PPMD activity is a form of community service which based on Tridharma state of universities, can be used as a small deterrent to introduce and encourage clean action to the community to maintain the cleanliness of the environment. The purpose of this study is to educate the public about the dangers of dumping activities in the river. The activities carr...

PT. KDLC Indonesia has five units of electrical energy generators with a total capacity of 400 MW. Each unit consists of one Boiler and one Turbine Generator. All fiveunits are using a manifold system that makes the Boilers and Turbine Generators from different units able to operate interchangeably. This paper studies how to determine a combined path of an optimum electricity production activity using Linear Programming method.It is suggested some steps, as well, that can be run to solve a probl...

This paper studies how to determine a combined path of an optimum electricity production activity using the Linear Programming method. According to Linear Programming, an optimum generation pattern is influenced by the demand factor, production capacity, raw material stock, operational cost, and efficiency of every unit. With an optimum combination of those aspects, the need for raw materials for each operating unit will be found out; therefore, a continuous and steady supply of raw materials ca...
