Study of Mathematical Modeling for Plant Disease Transmission: A Systematic Literature Review during 2012-2022

Many models representing disease transmission have been constructed and analyzed mathematically. However, literature studies on the mathematical models for vector-borne disease are sparse, especially on the plant disease transmission model. This study aims to obtain information about the research conducted and find room for developing the model, including mathematical analysis, intervention used, and biological factors considered. We employ a Systematic Literature Review (SLR) to explore all of the studies on plant disease transmission modeling collected from four digital databases. First, the JabRef reference manager helps conduct the inclusion and exclusion processing. Then, we obtain 60 selected articles that passed the criterion. Next, the VOSviewer application is resulting a bibliometric analysis of the database containing chosen articles. Finally, we classify the model constructed based on the system used and elaborate on the intervention used. The results show that the existing researcher clusters are not linked to each other, and the models only consider usual interventions such as roguing and insecticide spraying. Hence, there is much room to build collaboration between the researcher and develop models for plant disease transmission by considering the other various intervention and biological factors in the model to improve further

Kontrol Optimal Menggunakan A.aleyrodhis Penyebaran Penyakit Virus Kuning Pada Tanaman Terong

Dalam penelitian ini dibahas model matematis penyebaran penyakit kuning pada tanaman terong dengan protectant. Kami berasumsi bahwa protectant menggunkan ekstrak nabati daun pukul empat dapat meningkatkan sistem imun tanaman terong muda. Kami menunjukkan nilai Basic Reproduction Number (BRN)  dari transmisi penyakit tanaman. BRN dihitung dari nilai eigen terbesar dari Next generatin Matriks (NGM). Hasilnya menunjukkan bahwa jika ,  maka titik kesetimbangan endemik stabil, namun jika , maka titik ekuilibrium endemik menjadi tidak stabil. Kami juga membahas pengendalian kontrol optimal dari tanaman terong dan kutu kebul yang terinfeksi dengan mempertimbangkan pengobatan pencegahan menggunakan A.aleyrodhis yang bertujuan untuk mengurangi tanaman dan vektor yang terinfeksi dengan metode Pontrygain.. Hasil kontrol optimal menunjukkan A.aleyrodhis dapat mengurangi jumlah tanaman dan vektor yang terinfeksi dibandingkan tanpa kontrol

Wiener Index Calculation on the Benzenoid System: A Review Article

The Weiner index is considered one of the basic descriptors of fixed interconnection networks because it provides the average distance between any two nodes of the network. Many methods have been used by researchers to calculate the value of the Wiener index. starting from the brute force method to the invention of an algorithm to calculate the Wiener index without calculating the distance matrix. The application of the Wiener index is found in the molecular structure of organic compounds, especially the benzenoid system. The value of the Wiener index of a molecule is closely related to its physical and chemical properties. This paper will show a comprehensive bibliometric survey of peer-reviewed articles referring to the Wiener index of benzenoid. The Wiener index values of several benzenoid compounds using cubic polynomial are also reported. The Wiener index of benzenoid supports much of the research and provides productive citations for citing the study.   Keywords: Wiener index, benzenoid, distance matrix, chemical properties, cubic polynomial, topological
