Authors: Suriana  , Jamili
Published: May 2021

Apis cerena; is as wild bee or honey bee, widespread in almost all regions of Indonesia, these bee economic value as the honey it produces. Indonesian people, especially in Tanjung Peropa Southeast Sulawesi who use bees as a honey-producing source maintain honey bees with a honeycomb claim system that lives in hives in forested trees or found in people’s homes. Until now, there is no breeding or breeding business. Wobachia is endosimbiont which was infected Artrophoda, including insects, which can influence the dynamics of these insects population and can reduce insect perform and viability. Therefore, molecular detection of the presence of Wolbachia inApiscerenais important. The COI gene is a gene proposed as an animal barcode. There is evidence of primer use of the COI gene as a barcode which is often contaminated with Wolbachia COI gene which is not a target. The individual bee was extracted the genome DNA using the CTAB (cetyltrimethyl ammonium bromide) method, and then the cytochrome oxidase gene (COI) was umplified using an animal barcode primer. The amplification results are then sequenced and then characterized. Using Wolbachia COI gene data available on GenBank as a comparison, reconstruction of phylogenetic tree of Wobachian base on COI nucleotide sequences, so the position taxon of Wolbachia shall be determine. Phylogenetic tree reconstruction make with a Neiberjoining method with the Kimura 2-meter models and 1000x boostrapped. The results showed that the Wobachi COI gene was successfully amplified by these primer animal barcode, along 701bp. A proof that wild bees have been infected by Wolbachia. The findings of this study prove that PCR method are very sensitive to be used to detect existenceWolbachia in bees. This also means that the primer used to reveal animal barcodes, specifically vertebrates, can also amplify the Wolbachia gene; a Rickettsia. The gene has special characteristics, namely 633 base pairs (bp) conserved, and 24 bp variable nucleotides. Of these there are 12 nucleotides which unique for Wobachians who infectedA.cerenafrom Tanjung Peropa, Kendari Southeast Sulawesi. Base N composition dominated of Timine. The phylogenetic tree showed that Wolbachia fromApis cerena, is closely related to Wolbachia endosymbiont Hymenoptera, with 99% of boostrapped value.

Roads are needed To connect one location to another, but not all of them can be ascertained to have good land carrying capacity. The construction of a road body on land that has less bearing capacity (soft land) results in a large decrease and lateral movement. Soft soils are soils that if not carefully identified and investigated can cause problems of instability and long-term decline that cannot be tolerated, they have low shear strength and high compressibility. The method used in this research is experimental method. The test is carried out by looking at the deformation that occurs in soft soils which are not reinforced and in soft soils that are reinforced using plastic bottles woven on a wooden bus and with varying depths of flakes that are 10 cm and 20 cm, with a diameter of 10 cm wood pits. From the results of laboratory testing it is known that the combination of materials from woven plastic bottles and wood buses can reduce the deformation that occurs on soft soil. Deformation that occurs in soils not reinforced with a load of 4 kN is 25.89 mm, while the deformation that occurs in soils that are reinforced using woven plastic bottles on a bus wood pile and with a depth of 10 cm and 20 cm piles with the same load of 4 kN are 8.68 mm, 14.35 mm and 15.62 mm.

Delay is a common problem in project. In case of building project, the delay in project completion means that the user has to pay penalty corresponding to contractual agreement with the host. The construction of the Seberida Metering Station Engineering Procurement Construction & Commissioning (EPCC) project has been delayed. Based on the project’s physical progress scheduling report. The user demanded by the host to complete the project on time. One solution that can be done to overcome the project delay is to accelerate the duration of the project. However, the acceleration of the duration must be carefully calculated so that the project can be completed on time and the additional costs incurred as a consequence of reducing the duration do not swell. This Research uses the Time Cost Trade Off (TCTO) method as a solution to overcome delays, namely the method of scheduling projects by exchanging time and costs. From the results of the analysis with the Time Cost Trade Off method, it was found that the construction of the Metering Station was accelerated for 50 days, from the total duration of the project which normally takes 180 days to 130 days with an additional cost of $ 80,047.01.

Rubella disease is an infectious disease transmitted through the respiratory tract caused by a virus. In some cases, there are diseases that can enter an endemic condition, which is a condition in which the outbreak of a disease in a certain area over a long period of time. This condition can be modeled mathematically by using certain assumptions which will then seek for analytical and numerical solutions. This type of research is a literature study. This study examines the theory and application of the Runge-Kutta method in analyzing the spread of Rubella with the effect of vaccination. The Runge-Kutta method is widely used in solving ordinary differential equations and is more accurate than the Euler method. In this study, two methods were used to analyze it, namely the Runge-Kutta Order 4 and Order 5 methods which were used to analyze and compare the numerical results obtained, and the aim of the study was to obtain and interpret mathematically a mathematical model of the spread of Rubella’s disease with the effect of vaccination. and comparing the results obtained from the numerical solution using the Runge-Kutta Order 4 and Runge-Kutta Order 5 methods simulated with Maple software 13. From the results of this study, the results obtained in the 1st iteration of the numerical solution model for Rubella’s disease using the Runge-Kutta Order 4 is the value of 푆1 = 8771655, E
1 = 142, 퐼1 = 38, and R
1 = 30. While the results in the first iteration of the numerical solution model for Rubella’s disease using the Runge-Kutta Order 5 method were that the values of 푆1 = 8771759, E
1 = 142, 퐼1 = 37, and R
1 = 30 were obtained. So it can be concluded that the Order 5 Runge-Kutta is better than the Order 4 Runge-Kutta in predicting the state rate of the Rubella disease case population in the Suspectible, Exposed, Infected, Recovered, Suspected (SEIRS) model. Because the image / graph of Order 5 Runge-Kutta is more like / closer to the results of the analytical simulation using maple 13 software, which is as many as 27 infected individuals.

Published: May 2021

Moran’s I is commonly used to detect spatial autocorrelation in spatial data. However, Moran’s I may lead to underestimating spatial dependence when used for a small number of areas. This led to the development of Modified Moran’s I, which is designed to work when there are few areas. In this paper, both methods will be presented. Many R programs enable calculating Moran’s I, but to date, none have been available for calculating Modified Moran’s I. This paper aims to present both methods and provide the R code for calculating Modified Moran’s I, with an application to a case study of dengue fever across 14 regions in Makassar, Indonesia.

Infectious diseases are caused by microorganisms that can be transmitted directly or indirectly to humans. Understanding the characteristics of these diseases helps us to prevent and to overcome them. This study aims to discuss the profile of districts and cities in Southeast Sulawesi according to the spread of several types of infectious diseases by employing biplot and cluster analyses. The results showed that when the prevalence of tuberculosis is fairly high in a district or city, the HIV’s also follows. However, if these two diseases occur barely then the prevalence of malaria tends to be high, and vice versa. HIV is more likely to occur in Kota Kendari (Kendari City) and then followed by Buton and Konawe. In contrast, District of Muna with the lowest incidence of HIV and tuberculosis indicates the high prevalence of Malaria. The other types of diseases, such as pneumonia, DHF, and filariasis, are commonly found in Konawe Selatan and Kolaka.

Activities along the tributary of the Tallo river cause discoloration and unpleasant odors in the river water. This condition indicates that the river was polluted by anthropogenic waste. Therefore, a scientific study was conducted to determine the environmental conditions of the Tallo tributary through a preliminary study of the mineral characteristics of the surface sediments based on magnetic susceptibility data. The surface sediment was taken and its magnetic susceptibility measurements were carried out, followed by the interpretation of mineral types, element content, the presence of superparamagnetic minerals, and magnetic grains. The results showed that the minerals contained in the sediment samples were predominantly ferrimagnetic. The elemental content of the sediment samples indicated that Fe, Mn, and Cr were classified as heavy metals. Traces of the presence of superparamagnetic minerals show almost none. Meanwhile, the magnetic susceptibility values at low and high frequencies are identical, indicating that the grains contained in the sediment samples are multi-domain (MD), where the dominant magnetic minerals come from anthropogenic minerals.
