The complication of the procedure to claim the loss must follow several conditions. The different approaches in the insurance sector, using weather index can be taken into consideration to produce a variety of insurance products. This insurance product used the American put option with the primary asset is the rainfall and the cumulative rainfall to exercise the claim, considering the optimal execution limit. The homotopic analysis is used to determine the valuation of the American put option, which also becomes the insurance premium. The case study is focused on areas experiencing a drought so that insurance claims can be exercise when the rainfall index value is below a predetermined limit. Considering the normality of the rainfall data, the calculation of insurance premium was done for the first growing season. The insurance premium is varies based on the optimal execution limit, while the calculation of profit is based on the optimum limit exercise and the minimum rainfall for the growing season, and its different depended on insurance claim acceptance limits. 2021-01-01T00:00:00Z http://repository.president.ac.id/xmlui/handle/123456789/13861 PENGENALAN BISNIS KOPI KAYU MANIS KEPADA MAHASISWA AKADEMI KOMUNITAS PRESIDEN Ghofir, Abdul; Sahuri, Genta; Rahadi, Dedi Rianto Bagi sebagian masyarakat baik pria maupun wanita, kopi merupakan minuman wajib setiap hari.

Tren kopi yang semakin meningkat membuat bisnis kopi kian merebak. Berbagai cara orang melakukan bisnis kopi. Mulai dari bisnis yang sederhana seperti pedagang kaki lima hingga restoran berbintang. Persaingan yang tinggi membuat para pebisnis kopi harus pandai berinovasi. Berbekal dari kemampuan meracik kopi, kemudian sejumlah mahasiswa dan dosen Jurusan Manajemen President University membuat sebuah gagasan untuk meracik kopi dengan kayu manis. Racikan kopi kayu manis ini dikemas secara sederhana dalam sebuah botol plastik kecil berukuran 250 ml, yang kemudian dijual dengan harga yang sangat terjangkau baik online maupun offline. Kemampuan meracik dan berbisnis kopi kayu manis ini kemudian ditularkan kepada masyarakat lain yaitu Mahasiswa Akademi Komunitas Presiden. Prinsipnya adalah berbagi, berbagi pengetahuan, berbagi pengalaman, dan berbagi ceria. 2020-01-01T00:00:00Z http://repository.president.ac.id/xmlui/handle/123456789/13860 NETWORK DEFENSE SYSTEM MONITORING THROUGH A MOBILE APPLICATION Azrin, Lalu Muhammad Aryandi; Ghofir, Abdul This paper proposed a way to secure and protect pc or laptop remotely via mobile device. These two device communicate by exchanging information or data using database connection. There will be two applications that are developed, windows-based application and mobile application. The proposed scheme used some firewall configuration and log management to complete the process. The firewall configuration will block computer attacks such as Denial of Service. Log management is to generate a specific log file if there is a possible threat. It will then invoke. the windows application to update the database which is regularly accessed by mobile application. It then alerts user on possible attack or threat. 2019-01-01T00:00:00Z http://repository.president.ac.id/xmlui/handle/123456789/13859 MACHINERY HEALT MONITORING SYSTEM WITH ARDUINO Ghofi, Abdul; Phramoedya, Enda Machinery safety is the most important aspect needed around manufacturing or other engineering equipment. Machine guarding provides a means to protect humans from injury while working nearby or while operating equipment. Machinery that has rotary part such as turbines, pumps, fans, rollers, are needed to be monitored to report the vibration whether they are safety or not. Thus the preventive action is needed to ensure the safety of machinery before being used. This paper is about the monitoring system for machinery health which is developed with Arduino. It detects the vibration from the machine and information to mobile application. The information may include the vibration pattern, acceleration (g) value, recorded event, and also gives alert via mobile application in the form of vibration and ringtone. 2020-01-01T00:00:00Z
