Analisis Faktor Cuaca dengan Kejadian Demam Berdarah Dengue (DBD) di Kabupaten Wonogiri Tahun 2014-2018
Authors: Nur Latifah Endah , Darundiati Yusniar Hanani , Wahyuningsih Nur Endah 
Published: September 2021

Background:
Wonogiri Regency is one of the dengue endemic areas in Central Java with a fluctuating number of cases during 2014-2018. The number of dengue cases drastically increased nearly 4 times amounting 52 cases in 2016 to 207 cases in 2017. Weather factors such as rainfall, humidity, temperature, and wind velocity can affect the reproduction and spread of DHF vectors.
Objectives:
This study was aimed to analyze the association between weather factors (rainfall, humidity, temperature and wind velocity) with the incidence of dengue fever in Wonogiri Regency in 2014-2018.
Research Metodes:
This research was an analytic observational study using cross sectional approach. The type of data used was secondary data about the weather (rainfall, humidity, temperature and wind velocity) in Wonogiri Regency which was obtained from the Wonogiri Meteorological Station and data on the number of dengue incidents in Wonogiri Regency which were obtained from the Health Office of Central Java Province. The data were used each month for 5 years, from January 2014 to December 2018. Data were analyzed by using univariate and bivariate analysis (Rank Spearman correlation test), because only the humidity variable is normally distributed.
Results:
The highest number of dengue cases during 2014-2018 as many as 30 cases in November 2018 with an average of 6 cases, the highest rainfall was 887 mm with an average 191.05 mm, the highest humidity was 91.55% with an average of 86.77%, the highest temperature was 28.75oC with an average of 27.50oC and the highest wind velocity was 7.86 knots with an average of 0.89 knots. The results of the Spearman Rank correlation statistical test showed that there was a significant association with moderate strength and a positive direction between rainfall and the incidence of DHF (p = 0.001 and r = 0.420), which means that the increasing of rainfall, the more the number of DHF incidents. There was no significant association between humidity and the incidence of dengue fever (p = 0.925 and r = 0.012). There is a significant association with moderate strength and a negative direction between temperature and the incident of DHF (p = 0.001 and r = -0.415), which means that the increasing the temperature, the number of dengue cases decreases. There is no significant association between wind velocity and the incident of dengue (p = 0.577 and r = -0.073).
Conclusion:
Rainfall causes the breeding place of Aedes mosquitoes to increase, as a result it has an effect on the increase of the mosquito population. Temperature affects the number of eggs produced by Aedes mosquitoes, so that the density of adult mosquitoes increases.

Published: September 2021

Digital images are open to several manipulations and dropped cost of compact cameras and mobile phones due to the robust image editing tools. Image credibility is therefore become doubtful, particularly where photos have power, for instance, news reports and insurance claims in a criminal court. Images forensic methods therefore measure the integrity of image by apply different highly technical methods established in literatures. The present work deals with copy move forgery images of Media Integration and Communication Center Forgery (MICC-F2000) dataset for detecting and revealing the areas that have been tampered portion in the image, the image is sectioned into non overlapping blocks using Simple liner iterative clustering (SLIC) method. Then, Scale invariant feature transform (SIFT) descriptor is applied on the grey of the handled image to gives distinctive key points that classified by K-Nearest neighbor to detect and localize the forged portion in the tempered image. The forgery detection results gave a performance percent of about 98%, which reflects the ability of the KNN classifier that cooperated with SIFT descriptor to detect the forged portions even if the forged area is rotated or scaled or both of them.
Playfair with Multi Strata Encryption
Authors: Salih Raghad K. , Yousif Madeha Sh. 
Published: September 2021

Playfair cipher is a substitution scheme. The classical playfair scheme has a limited matrix size containing only uppercase letters, so it is prone to hackers and cryptanalysis. To increase the resistance of playfair cipher, a new encipherment and decipherment method is proposed in this work, which depends on the permutation and its inverse, respectively. In addition, a modified key matrix is utilized, which includes capital and small Alphabets, numbers, and 38 special characters collected from ASCII codes. In the proposed method, both substitution and transposition schemes are used, where the first stratum of the cipher is a substitution by using key matrix and the second stratum is a transposition by using permutation key which provides multi strata resistance to brute force and other cryptanalysis attacks. A comparison between the traditional playfair scheme and the proposed method demonstrates that the encoded text is hard to recognize by cryptanalysts, which improves the security of the encryption process.

Retained foreign needle in the thoracic spinal canal in a child: Case report
Authors: Kawtharani Sarah , Bsat Shadi Abdelatif , El Houshiemy Mohamad , Moussalem Charbel , Halaoui Adham , Omeis Ibrahim 
Published: September 2021

Background:
The presence of retained foreign bodies in the spinal canal has been reported in the literature. They are attributed to retained pieces of medical equipment after surgery, or, following trauma, to residual bullets, glass fragments, or knife blades. Although some retained materials do not cause any neurological deficits in the short run, others may become symptomatic months later.

Case Description:
A 2-year-old male presented with a history of intermittent fever and mild lower extremity weakness. Notably, the original infectious workup was negative. However, a noncontrast CT scan later documented a needle-shaped foreign body in the spinal canal at the T10 level. During the T10 laminectomy, a needle (i.e. from a medical syringe) was removed, the patient remained neurologically intact. The foreign body turned out to be a medical syringe needle tip.

Conclusion:
A 2-year-old male presented with fevers and mild lower extremity weakness attributed to an intraspinal needle tip found utilizing CT at the T10 level. T10 laminectomy allowed for removal of a small needle tip. This shows the importance of removing retained spinal foreign bodies to avoid further/future neurological injury, and/or the potential risks/complications of foreign body migration/sequestration.
PENGARUH AGING DAN VARIASI KECEPATAN PUTARAN TERHADAP LAJU KOROSI PROPELLER BERBAHAN ALUMINIUM PADUAN
Authors: KAROKARO HENDRA SETIAWAN 
Published: September 2021

Salah satu bahan baling-baling yang banyak digunakan adalah aluminium paduan. Kerusakan propeller yang terjadi di dominasi oleh terjadinya patah pada salah satu atau beberapa daunnya. Kerusakan berupa patahnya propeller tidak hanya disebabkan oleh beban kerja propeller, melainkan sebagai hasil akumulasi antara kerja propeller dan lingkungan kerjanya yang korosif. Salah satu cara meningkatkan sifat mekanis paduan aluminium adalah dengan perlakuan panas penuaan (aging treatment). Penelitian ini bertujuan untuk mendapatkan laju korosi akibat pengaruh kecepatan putaran propeller dan aging. Pada penelitian ini material Al paduan di-aging pada temperatur 170°C selama 180 menit. Material tanpa aging dan hasil aging kemudian diuji korosi dengan metode celup pada variasi putaran propeller 800 rpm, 1000 rpm, 1200, dan 1500 rpm dengan waktu perendaman 12 jam , 24 jam, 48 jam,dan 168 jam. Hasil penelitian menunjukan bahwa kecepatan putaran propeller mempengaruhi laju korosi material. Spesimen yang diputar pada kecepatan 1500 rpm memiliki laju korosi 1,0084 mm/year untuk material tanpa aging dan 0,9447 mm/year untuk material dengan aging. Laju korosi ini lebih besar dibandingkan spesimen yang diputar pada kecepatan 800 rpm, 1000 rpm dan 1200 rpm. Laju korosi pada putaran 800 rpm adalah 0,6472 mm/year untuk material tanpa aging dan 0,5141 mm/year Utuk material dengan aging. Aging yang dilakukan pada material dapat menurunkan laju korosi dari 0,6472 mm/year menjadi 0,5141 mm/year pada putaran 800 rpm, 0,7913 mm/year Menjadi 0,6775 mm/year pada putaran 1000 rpm, 0,8805 mm/year menjadi 7438 mm/year Pada putaran 1200 rpm dan 1,0084 mm/year menjadi 0,9447 mm year pada putaran 1500 rpm. Pengamatan foto mikro menunjukan bahwa jenis korosi yang terjadi adalah korosi kavitasi.
