Abstract

The Blumberg model is one of the logistic models. The advantage of the Blumberg model is the flexibility of the inflection point. The Blumberg model is believed to be suitable for modeling the growth of living organs. In this article, we estimate the parameters of the Blumberg model using simulated annealing algorithm. The simulated annealing algorithm is a heuristic optimization method based on the metal annealing process. The data used is Broiler daily weight data. The model obtained fits the daily weight data of Broiler. Our results show that the closer the cooling schedule factor to 1, the smaller the error. In addition, we must carefully select the initial temperature. The selection of the initial temperature that is not suitable drives the error to enlarge.

Abstract

Foot and Mouth Disease (FMD) is a highly contagious disease that can infect all cloven hoofed animals. FMD is one of the most important infectious viral diseases in the world. This disease is responsible for international losses in livestock production and trade. In this article, we formulate a mathematical model for the spread of FMD in goat farms that considers early quarantine, vaccination, and disinfection interventions. The model constructed is expressed as a system of ordinary differential equations consisting of eight state variables. We determine the basic reproduction number using the next-generation matrix method. Our numerical simulation results show that vaccination has a very crucial role in controlling the spread of FMD and reducing the basic reproduction number. In addition, quarantine interventions for latent and infectious goats are also effective in controlling the spread of FMD. The basic reproduction number can also be suppressed by disinfection and quarantine interventions. Therefore, we recommend implementing routine vaccination, screening and disinfection programs. In addition, farmer should be given education so that they have the ability to identify goats exposed to FMDV so that quarantine can be carried out early.

Abstract

Pelatihan Microsoft Office 2021 yang diberikan kepada para guru TK Dasa Wisma Apala Kabupaten Bone merupakan kegiatan yang diadakan untuk meningkatkan keterampilan dalam menggunakan teknologi di era Revolusi Industri Keempat. Kegiatan ini difokuskan pada pelatihan Microsoft Word dan Microsoft Excel untuk mendukung optimalisasi pengelolaan administrasi dan penyusunan RKAS serta penyusunan laporan tahunan di sekolah mitra. Tim kami melakukan pelatihan dengan menggunakan metode konseling partisipatif dan metode demonstrasi serta praktik langsung oleh peserta. Hasil dari pelatihan ini menunjukkan bahwa keinginan untuk mengenal dan menggunakan teknologi di sekolah mitra sangat besar. Selain itu, di akhir pelatihan, para peserta mampu menggunakan Microsoft Word dan Microsoft Excel untuk mengisi atau mengedit template RKAS. Oleh karena itu, dapat disimpulkan bahwa pelatihan yang dilakukan telah berhasil.

Abstract

Maleo is a large megapod found on the island of Sulawesi and surrounding islands and is an endangered species due to illegal hunting and habitat conversion. In this article, we propose a mathematical model for Maleo conservation. The model that is constructed is expressed as a system of ordinary differential equations consisting of five equations. To study the optimal strategy, we use optimal control theory. In our model there are three control parameters related to guarding Maleo nests, monitoring Maleo habitats, and transferring Maleo eggs to captivity. To measure the impact and the consequences of each intervention scheme, we determine the percentage increase in the Maleo population and the average cost-effectiveness ratio. Our results show that the most effective intervention scheme to increase Maleo populations is a combination of guarding Maleo nests, monitoring Maleo habitats, and transferring Maleo eggs to captivity. Meanwhile, the intervention scheme that has the best cost-effectiveness is the intervention scheme which is a combination of guarding Maleo nests and monitoring Maleo habitats.
