Abstract

Gelanggang Village is one of the villages located in East Sakra District, East Lombok Regency, which has great potential in the agricultural sector and almost 90% of the people living in Gelanggang village work as farmers. However, other plants such as vegetables, which are one of the food necessities, are not widely planted and cultivated, because they are considered less productive for the community. Apart from that, the people of Gelanggang village also have large plots of land which are not utilized. The aim of the main KKN-PMD program activities in Gelanggang Village is to provide education regarding the use of residents' yards for cultivating vegetable crops and increasing the food security of the Gelanggang Village community. The stages in carrying out the main KKN-PMD work program activities in Gelanggang Village are the first stage sowing vegetable seeds, the second stage making Verticulture shelves and the last stage carrying out outreach. The result obtained from this activity is that by conducting outreach related to vegetable cultivation, this can provide education regarding the use of residents' yard land for cultivating vegetable plants. Apart from that, this outreach is also an effort to increase the food security of the Gelanggang village community

Abstract

Curah hujan dapat dianalogikan sebagai sebuah populasi yang terus tumbuh dan berkembang, namun pertumbuhannya terbatas. Curah hujan dapat tumbuh dikarenakan uap air yang berasal dari peristiwa kondensasi. Pertumbuhan curah hujan dapat dimodelkan ke dalam bentuk model pertumbuhan logistik. Salah satu model matematika yang merupakan bentuk model pertumbuhan logistik adalah model predator-prey atau model mangsa-pemangsa. Data curah hujan dan predator-prey sama-sama memiliki nilai yang selalu positif atau tidak pernah negatif. Model predator-prey belum pernah digunakan untuk memodelkan data curah hujan. Tujuan dari penelitian ini adalah untuk mengetahui model predator-prey dalam menggambarkan model curah hujan dan untuk mengetahui estimasi parameter persamaan predator-prey yang sesuai dengan kasus curah hujan. Hasil penelitian ini menunjukkan model predator-prey yang menggambarkan kasus curah hujan adalah model sebagai predator, dengan estimasi nilai parameter diperoleh dari pendekatan analisis persamaan titik ekuilibrium predator-prey, frekuensi sudut dan periode dari stabilitas titik ekuilibrium center pada persamaan predator-prey.
