Abstract

Dengue is one of the mosquito-borne diseases caused by dengue viruses (DENV), which has become endemic in most tropical and subtropical countries, including Indonesia. Since there is a lot of dengue incidence on children of age less than fourteen years old in Semarang, Indonesia, it is the interest here to analyze the different rates of infection among different age groups. A SIR-UV mathematical model with age structure in human the population is constructed to describe dengue transmission in Semarang from 2015 to 2018. In this study, we separated the human population into four age classes: children (0-4 years), youngster (5-14 years), productive adults (15-60 years) and non-productive adults (over 60 years). We use Particle Swarm  Optimization to obtain optimal parameters for the transmission rates based on the yearly incidence. The basic reproduction ratio (R0) is derived from the Next Generation Matrix and is evaluated by using the optimal parameters for data Semarang in 2015-2018. Numerical simulation results show that the number of dengue incidence is in a good agreement with the actual data in Semarang for 2015-2018.

Abstract

The coral reef ecosystem in Indonesian as part of Coral Triangle Region has been significantly decreasing in the last decades. This damage has been known widely due to coastal development, pollution, and uncontrolled fishing and harvesting. Among other many living species in the environment, the existence of coral reefs is directly related to the existence of Drupella sp. and Acanthaster planci as the coral predators, while the existence of the predators also related to the Napoleon wrasse and Giant triton/ Trumpet shell as the top predator. This study discusses the interaction among the coral reefs, the predators and the top predators, which is represented in a dynamical model of predator-prey-top predator. In the absence of top predators, the system is reduced as a two-predator-prey model with only one surviving predator, Acanthaster planci, which has more effective predation behavior. The role of Napoleon wrasse as a top predator of both Acanthaster planci and Drupella sp. is significantly important to protect the coral reef from the excessive predation from Acanthaster planci and Drupella sp. A stable co-existence is shown between coral reef, Acanthaster planci and Napoleon wrasse. With the appearance of Giant tritons which predate only Acanthaster planci, a co-existence between five species may occur with abundant species of Giant triton.

Abstract

The West Nile virus (WNV) is transmitted through the bites of infected mosquitoes. The spread of WNV in chicken populations is quite unique. Although chickens can contract the virus through a mosquito bite, they immediately build immunity to the virus and do not show physical symptoms of illness and hence chickens are only temporary carriers of the virus. Recently, experimental results have shown that mosquitoes do not change fecundity behavior, yet results indicate that resistance to infection is associated with afitness cost in terms of mosquito survival. We constructed a host-vector type transmission model for WNV in mosquito-chicken populations. The basicreproductive ratio, Ro , was obtained. From sensitivity analysis of Ro it was shown that under certain conditions this ratio decrease "“ with an increase of the lifetime of mosquito infection.

Abstract

A number of benign EEG patterns are often misinterpreted as interictal epileptiform discharges (IEDs) because of their epileptiform appearances, one of them is wicket spike. Differentiating wicket spike from IEDs may help in preventing epilepsy misdiagnosis. The temporal location of IEDs and wicket spike were chosen from 143 EEG recordings. Amplitude, duration and angles were measured from the wave triangles and were used as the variables. In this study, linear discriminant analysis is used to create the formula to differentiate wicket spike from IEDs consisting spike and sharp waves. We obtained a formula with excellent accuracy. This study emphasizes the need for objective criteria to distinguish wicket spike from IEDs to avoid misreading of the EEG and misdiagnosis of epilepsy.

Abstract

Python programming is a multipurpose interpretive programming language with a design philosophy that focuses on code readability. Python is a language that combines capabilities with very clear code syntax and is equipped with the functionality of a large and comprehensive standard library. Python supports multiple programming paradigms. One of the features available in Python is that it is a dynamic programming language equipped with automatic memory management. This Community Service Activity is carried out by providing training material starting from a basic introduction to the Python programming language, basic rules for writing Python syntax, an introduction to variables and data types in Python, operators in Python, and learning structures and functions in Python. The mentoring process is also carried out to provide direct experience to students. This activity went well and received appreciation from the school, and the students hope that this activity can be continued so that students are able to apply Python programming well.

Abstract

The prevalence of Schistosomiasis cases in Poso Regency specifically in Napu and Bada changes every year and in 2021 there was a significant increase in cases. Therefore it is necessary to predict cases in 2022 or the 13th and 14th semesters using Lagrange extrapolation. The prediction results of the cases number in Napu in 13th and 14th semesters are 461 and 5445 for humans, 12442 and 43045 for snails, and 1370 and 4789 for rats respectively. The prediction results in Bada in the 13th and 14th semesters are 202 and 984 cases for humans, -804 and -2863 cases for snails, and -251 and -890 cases for rats respectively. The Lagrange polynomial errors are −0,16335 × 10−5 and −0,8629 × 10−5 for the 13th and 14th semesters for humans, 0,578 × 10−7 and 0,2288 × 10−7 the for 13th and 14th semesters for snails and rats. Some of the predictions were unrealistic, so the Lagrange extrapolation method is not appropriate for predicting Schistosomiasis cases.
