Abstract

Dengue Haemorrhagic Fever is an endemic disease caused by dengue virus and transmitted to humans through female Aedes aegypti mosquitoes. Surabaya, Sidoarjo and Gresik are 3 cities in East Java which have the highest density of Aedes aegypti larvae in 2013 – 2016. This research aims to isolate the Native Entomopathogenic Bacillus sp. from Soil Sediment of Water Reservoir of Breeding sites of Aedes aegypti and to know their potential biolarvacidal potency against Aedes aegypti larvae. The Soil sediments were taken from 10 sites in Surabaya, 10 sites in Sidoarjo and 10 sites in Gresik. Isolation of bacteria was performed using growth media of Bacillus sp., identified with Gram and spore stainings, and biolarvacidal potency test was performed on the third instar larval stage of Aedes Aegypti. Eight Native Entomopathogenic Bacillus sp. were isolated and those isolates were toxic to the third instar larvae of Aedes Aegypti more than 50% mortality. The highest level of killing power of these Bacillus sp. are isolate from Gresik, G6.4 which has 100% mortality, then followed by isolates from Surabaya, S7.3 and S4.3 which has 96,7% mortality and S4.5 which has 80% mortality at 48 hours exposure time with the same optical density (A600 nm = 0,8).

Abstract

This research aims to isolate local entomopathogenic bacteria Bacillus sp. from the body of Aedes aegypti larvae and to know the potency of local entomopathogenic bacteria Bacillus sp. in killing Aedes aegypti III instar larvae. This research is descriptive study with qualitative and quantitative approaches. Bacillus sp. was isolated by destroying the larvae sample and heated in a temperature of 70ºC. Then, the sample was diluted 10-1–10-3. After that, each dilution was grown for 48 hours. Then, purification of bacteria suspected as Bacillus was performed. Gram staining and spore staining as microscopic tests were carried out on colonies that resembled Bacillus sp.. Bacillus sp isolate which have been obtained was used in preliminary and advanced stages of potential test against instar larvae III of Aedes aegypti. Data was visualized in tables and graphs, then analyzed descriptively. The results of the study showed that in the preliminary stage of potential test, 120 isolates of Bacillus sp. were obtained, as many as 32% had no potency, 41% had low potency, 15% had moderate potency, and 12% had high potency. The results of the advanced stage of potential tests on high-potential isolates showed 3 isolates with the highest potency in killing Aedes aegypti larvae. They were SB3 3, SB9 1, and SD4 2 with percentage of larval mortality of 100%, 96.7%, and 100%, respectively.

Abstract

The Uncapacitated Facility Location Problem (UFLP) is a problem that aims to find the optimal location for building facilities where these facilities will serve a number of m customers. Additionally, there are a set of n locations available to build n facilities. In this problem, it is assumed that the facilities have no capacity limitations in serving customers, meaning that all demands from each customer are served by a single facility, and there is only one facility at each location. The objective function of the UFLP is to minimize the total cost. This research aims to apply the Harmony Search (HS) algorithm and Simulated Annealing (SA) algorithm to solve the Uncapacitated Facility Location Problem (UFLP). The HS algorithm, developed by Geem et al. (2001), is a method based on the process of a musician searching for the right harmony through three modes of note searching: replacing the old note, modifying the old note slightly, or changing the old note based on the musician's memory. The SA algorithm, developed by Dreo et al. (2006), mimics the annealing process in crystal hardening. To produce high-quality crystals, the temperature must be lowered, then slightly raised before being lowered again. The solution to this problem involves several processes, including initializing parameters such as Harmony Memory Size (HMS), Harmony Memory Considering (or Accepting) Rate (HMCR), Pitch Adjusting Rate (PAR), bandwidth, initial temperature , temperature decay rate (), final temperature , and maximum iterations; then generating the Harmony Memory (HM) population, calculating the objective function values for HM, evaluating the objective function for HM, modifying the worst individual in HM, checking the modification results, applying the SA modification, checking the SA modification results, determining the best solution in HM, checking for the maximum iterations, and finally calculating the total cost.

Abstract

AIDS is a collection of symptoms of infectious diseases that arise as a result of the weakened immune system of the patient, caused by the HIV (Human Immunodeficiency Virus). Mathematical models play an important role in understanding the dynamics of HIV/AIDS transmission, especially with the presence of treatment, and can be used to predict its spread through numerical simulations of the mathematical model of HIV/AIDS transmission with treatment. This research discusses the analysis of a fractional-order mathematical model of HIV/AIDS transmission with treatment. The model is a modification of the nonlinear Ordinary Differential Equation (ODE) system into a Fractional Differential Equation (FDE) system. Generally, solutions to nonlinear ODEs are difficult to find analytically. However, a mathematical model that can be solved analytically is the Fractional Differential Equation (FDE) system. One method for solving FDEs is using the Homotopy Perturbation Method (HPM), which transforms the FDE into a Homotopy Differential Equation system by multiplying each equation in the FDE with an embedding parameter (p). The solution is expressed as an infinite series, which is then solved numerically. As the fractional derivative order increases, the changes in the graph of the healthy population susceptible to HIV/AIDS infection, the population infected with HIV/AIDS, the population with full-blown AIDS not receiving ARV treatment, the population receiving ARV treatment, and the healthy population changing lifestyle patterns, become faster.

Abstract

Ternary semiring was first introduced by Dutta dan Kar in 2003. Ternary semiring is a generalization of ternary ring. Ternary semiring is an algebraic structure consisting of a nonempty set together with a binary operation, called addition and a ternary multiplication, which forms a commutative monoid relative to binary addition, monoid relative to ternary multiplication, and the left, lateral, and right distributive laws hold. In this research, we use method of literature study on article which have published in international journal. In this research, we study more several parts of research from Dutta and Mandal about 2-primal ternary semirings, but will focus only on ternary semiring, including some ideals, prime radical, nilpotent element, super nilpotent ternary semiring, and 2-primal ternary semiring. Next, a more detailed discussion will be provided and accompanied by several examples using sets of matrices.
