Gender specificity of reactivity rat skins microvessels according to laser doppler flowmetry
Authors: Chkhaidze I. Z.
Published: December 2022

Introduction. In the development of systemic microcirculation disorders, gender is known to have a certain significance. However, the features of the microvessels reactivity and their functional reserve have not been sufficiently studied.

   Purpose – to study the gender specificity of the microvessels reactivity of rat skin according to LDF data in the conditions of functional tests.

   Materials and methods. The study was carried out on male and female Wistar rats. Females with a stable 4-day estrous cycle according to colpocytogram data were selected for the experiment. The LDF method was used to evaluate the initial skin perfusion and its dynamics under the conditions of a test with local contact hypothermia induced by a thermoelement. The distribution of temperature fields was evaluated using a FLIR ONE Pro thermal imaging camera.

   Results. While contact cooling of the skin, microvessels developed a reaction having phase pattern. Immediately after exposure, local contact hypothermia was accompanied by a significant decrease in skin temperature and tissue perfusion (in the area of laser flowmetry). At the same time, males had higher percentage of reduction in skin blood flow (Q %) than females and amounted to 54 % of the initial values. The maximum perfusion after the restoration of blood flow was noted at the 5th minute in males, at the 3rd minute in females and amounted to 147 % and 149.9 %, respectively. The initial blood flow in the skin microvessels in different phases of the estrous cycle in females did not differ significantly. However, when conducting a functional test in the proestrus stage, characterized by the maximum secretion of estrogens by the ovaries, vasoconstriction was less pronounced than in other phases of the cycle.

   Conclusion. The revealed features of blood flow reduction followed by «cold vasodilation» under conditions of local contact hypothermia tests indicate a greater functional reserve of microvessels and a more effective mechanism of autoregulation of the microcirculation system in female rats.

Published: December 2022

Introduction. Age-related changes of blood flow parameters and hepatic portal vein wall morphometry are one of the topical and insufficiently investigated issues of liver hemodynamics.

   The aim was to study changes of portal hemodynamics and to analyze the portal vein wall morphometry of rats at different age periods.

   Materials and methods. 60 mongrel rats of both sexes weighing 120–350 g were divided into three age groups. The first group included 20 rats aged 1 month, the second – 20 rats aged 6–12 months and the third – 20 rats aged more than 18–24 months. The qualitative and quantitative portal vein hemodynamics parameters were obtained by ultrasound scanners under zoletil-xylazine anesthesia. Morphometric examination of the portal vein was performed. Digital data were processed by methods of variational statistics.

   Results. The diameter of the portal vein in groups II and III was greater than the corresponding parameter in group I (R = – 0.40 and R = 0.64, respectively). The time-averaged average blood flow rate in the II age group increased by 9.11 % compared to the I group, decreased by 10.43 % in the III group (the differences are statistically unreliable). The volumetric blood flow rate increased moderately in age groups II and III compared to group I (by 13.07 and 11.13 %, respectively; the difference is statistically unreliable). The ratio of the volumetric blood flow rate to the weight of the animal in the II age group increased by 3.85 % compared to the I group, decreased by 11.54 % in the III group (the differences are statistically unreliable). Since the mass of animals significantly increased with age, the portal vein volumetric blood flow of old animals is likely to be decreased. Mature and old rats demonstrated significant decrease of the muscle membrane thickness, the Kernogan index and the width of the collagen layer.   Conclusion. Age-related changes of rats portal hemodynamics resulted in a slight reliable increase of portal vein diameter and its cross-sectional area. Linear and volumetric parameters of blood flow were found not to have statistically reliable dependence on the age and weight of animals. Morphometric parameters of the rats portal vein wall were revealed to have pronounced changes in different age groups. The aging of the portal vein wall of elder rats consisted in a significant decrease of the muscle membrane thickness, the Kernogan index and the width of the collagen layer.
Hyper IgE syndrome with autoimmune hemolytic anemia in Saudi Arabia
Authors: Alabdullatif Saad , Alhashim Hassan , Alhussain Mohammed , Alnajim Fahad
Published: December 2022

Background: Hyper IgE syndrome (HIES) is a rare primary immunodeficiency disorder characterized by elevated serum immunoglobulin E (IgE) levels. Autosomal dominant and autosomal recessive forms of HIES have been reported. Autosomal recessive HIES typically includes a history of asthma, atopic dermatitis, food allergy, and recurrent viral infection. HIES diagnosis requires genetic study, which is time-consuming and not always feasible.
Case Presentation: We report the case of an 8-year-old female. The patient recently presented to our emergency department with pallor and syncope. Upon examination, the hemoglobin level was 4.9 g/dl. Direct antiglobulin test showed a positive result. The patient had an admitting diagnosis of autoimmune hemolytic anemia, a rare complication of autosomal recessive HIES. The patient is a known case of asthma, herpetiformis dermatitis, nut allergy, and allergic rhinitis. HIES was the first possible diagnosis, which was further confirmed by clinical presentation and a high serum IgE count. The patient was referred to a tertiary care center for genetic counseling and further follow-up.
Conclusion: HIES is a rare immune deficiency disorder that can be inherited in either an autosomal dominant or recessive pattern. Although these two types show similar clinical presentations, certain features remain distinct, providing a valuable insight into the final diagnosis even without the gene study results. To the best of our knowledge, no study has evaluated HIES in general, and no case report has evaluated autosomal recessive HIES in Saudi Arabia. This case study will guide the medical community in the early-stage diagnosis and management of HIES.

Published: December 2022

Background. The present study was designed to evaluate the effect of melatonin on the sleep initiation, duration of sleep, quality of sleep and daily performance in healthy children suffering from insomnia.
Methods. This study was done as a double blind randomized clinical trial in the sleep clinic of Qods Hospital. Sixty healthy children between 7 and 12 years of age having sleep problems were chosen and randomly divided in interventional and placebo groups. Before the treatment, children`s sleep habits questionnaire (CSHQ) was filled in both groups. Then, both groups were taught about sleep hygiene. Afterwards, the intervention group was treated with 3mg nocturnal dose of melatonin for one month and the other group with a placebo. Then, CSHQ was filled again for both groups. The intervention was Melatonin. The mean analyzed results of the variants in pre-test and post-test were compared and p < 0.05 was regarded as significant.
Results. Results showed that Melatonin with no side effect is effective in improving: 1- The initiation and maintenance of sleep, 2- Sleep onset delay, 3- Sleep duration, 4- Sleep anxiety, 5- Nightly awakenings 6- Parasomnias and 7- daily performance; but is ineffective in bedtime resistance and sleep disordered breathing.
Conclusions. Our results indicate that melatonin is more effective than placebo in improving the initiation and maintenance of sleep and most of its subscales in primary school aged children.

Authors: Öztürk Filiz Halıcı , Türkmen Gülenay Gençosmanoğlu , Ergun Elif , Tiryaki H Tuğrul , Şahin Dilek
Published: December 2022

Background. Congenital megalourethra is an uncommon cause of lower urinary tract obstruction that is rarely prenatally diagnosed in second trimester sonographic examination as a cystic genital mass.
Case. In the presented case, the megalourethra was accompanied with bilateral mild pelviectasis. The newborn had no morbidity during follow-up period. To review the literature, electronic databases including PubMed, Web of Science and Google Scholar were searched up to February 15, 2021. In 51 prenatally diagnosed cases in the literature, most of the cases had accompanying congenital anomalies, especially structural abnormalities in the genitourinary.
Conclusions. In the absence of associated abnormalities, the condition of the upper urinary tract is the main determinant of postnatal outcome. The outcome of congenital megalourethra may be good as in our case, but there may also be serious disorders such as renal failure, pulmonary hypoplasia, erectile dysfunction and fertility issues.
Relationship between placental autophagy and inflammasome activities with morbidity of extremely preterm infants
Authors: Deliloğlu Burak , Tüzün Funda , Aysal Anıl , Duman Nuray , Özkan Hasan , Özer Erdener
Published: December 2022

Background. The placenta is the major regulatory element of the in-utero environment, and alterations in placental cellular functions in infection, inflammation, and hypoxemia lead to adverse preterm birth outcomes. The importance of regulation of autophagy and inflammasome activities has been shown in the pathogenesis of morbidities in immature animal models. This study aimed to determine the relationship between placental autophagy and inflammasome activities with morbidity in extremely preterm infants.
Methods. Premature infants born between 24th to 29th gestational weeks were evaluated prospectively. Placental LC3B and NLRP3 immunostainings were performed to assess autophagy and inflammasome activities. Preterm morbidities including respiratory distress syndrome (RDS), patent ductus ateriosus: (PDA), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), periventricular leukomalacia (PVL), sepsis, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP) and mortality were evaluated.
Results. Fifty-nine infants with a mean gestational age of 26.9 ± 1.5 weeks were included. Anti-LC3B staining scores were moderate or intense positive in 75% of the placentas. Anti-LC3B activity was not associated with the existance of evaluated neonatal morbidities or mortality. Autophagy and inflammasome coexistence were demonstrated in 35 placentas (59.3%). Anti-NLRP3 staining score was moderate or intensely positive in 75% of the placentas. Infants with BPD had a lower rate of positive anti -NLRP3 staining than infants without BPD (42.9 vs 57.1%, p=0.048). Infants who had hemodynamic significant patent ductus arteriosus (hsPDA) and surgical- NEC showed significantly intense anti-NLRP3 staining compared to infants who did not (18.8% vs 0%, p= 0.027 and 33% vs 7.5%, p=0.048 respectively).
Conclusions. The results showed that autophagy and inflammatory activities were present in varying amounts in the placenta of preterm infants. Association of decreased or increased rates of inflammasome activities with certain diseases such as BPD, hsPDA and surgical-NEC indicates the role of the intrauterin inflammatory process and the importance of critical balance in inflammation. Because of the complex pathophysiology of preterm morbidities, placental autophagy and inflammasome activities seem worthy of further investigation.

Authors: Behura Sushree Smita , Dhanawat Avantika , Nayak Biswajit , Panda Santosh Kumar
Published: December 2022

Background. Preterm neonates perceive multiple painful procedures during Neonatal Intensive Care Unit (NICU) stay, having long term neurobehavioral effects. This study aims to compare the analgesic efficacy of oral melatonin with 24% sucrose in neonates during retinopathy of prematurity (ROP) screening.
Methods. A prospective, non-blinded, randomized controlled trial was conducted in a tertiary care NICU. All preterm neonates with gestational age (GA) < 34 weeks or birth weight (BW) < 2000 grams eligible for ROP screening were randomized into oral melatonin (4 mg/kg) and oral 24% sucrose (0.5 ml) groups. Both groups received standard non-pharmacological measures and topical proparacaine. The intensity of pain was measured by Premature Infant Pain Profile (PIPP) score during the procedure, at 1st and 5th minutes following the procedure and compared between the two groups by Mann-Whitney U test with p value < 0.05 considered as significant.
Results. A total of 60 preterm neonates were randomized with 30 neonates in the melatonin (median [interquartile range] GA: 30.86 [3.78] weeks, BW: 1160 [430] grams) and 30 neonates in the 24% sucrose (median [IQR] GA: 29.29 [4.68] weeks, BW: 1070 [315] grams) group. The median PIPP score during the procedure in the melatonin and sucrose groups were 17 and 16, respectively (p=0.64). The median (Q1-Q3) PIPP score at the 1st minute was significantly lower among the melatonin group (7 [5.25-10]) vs 24% sucrose group (9.5 [7.25-11]) (p=0.02); and at the 5th minute, the median (Q1-Q3) PIPP scores in the melatonin group (5 [4-6]) was comparable to the 24% sucrose group (5.5 [3.25-7]) (p= 0.52).
Conclusions. Oral melatonin is not inferior to oral 24% sucrose for pain management during ROP screening.

Authors: Çetiner Nilüfer , Çeliker Alpay
Published: December 2022

Background. The cardiopulmonary exercise test is accepted as a helpful diagnostic tool in risk stratification, evaluation of prognosis, and guiding treatment modality in adults with congenital heart disease. In this study, we present our experience with the use of cardiopulmonary exercise test in children with congenital heart disease in different physiological and anatomical classifications.
Methods. In this retrospective study, 25 children and adolescents who applied to the pediatric cardiology outpatient clinic between 2017 and 2020 with the diagnosis of different types of congenital heart disease were included. Demographic characteristics, electrocardiogram, echocardiogram, cardiopulmonary exercise test, spirometry, pro-BNP values, and in selected 20 patients; cardiac MRI data were examined. The modified Ross classification was used for heart failure grading.
Results. The mean age of the patients was 14.8 ±2.39 years. Fifteen (60%) of the patients were male and 10 (40%) were female. In the modified Ross classification, patients in group I-II had significantly higher maximum exercise time, heart rate reserve %, peak VO2, and VO2/kg values compared to those in group III (p=0.026, p=0.007, p=0.043, p= 0.018, respectively). Cardiopulmonary exercise test and spirometry values obtained from the patients were evaluated in the light of clinical and other laboratory findings, and surgical/interventional treatment was decided for 4 patients with the use of these test results.
Conclusions. Cardiopulmonary exercise test is a useful noninvasive diagnostic tool in guiding the treatment decision and predicting the prognosis of pediatric patients with congenital heart disease, who have borderline symptoms.
Duodenal Dieulafoy lesion: a rare pathogeny of gastrointestinal bleeding in children
Authors: Chao Liu , Lei Zhang , Xiang Li
Published: December 2022

Background. Dieulafoy lesion is a calibre persistent submucosal artery associated with a minuter mucosal defect. Dieulafoy lesion has been reported to account for 1-5.8% of acute nonvariceal upper gastrointestinal bleeding in adults, but it is rarely reported in children.
Case. Here we report a case of duodenal Dieulafoy lesion in a 13-year-old boy. After endoscopy and laparotomy, he still had no definite diagnosis and effective treatment. The duodenal Dieulafoy lesion was finally identified by selective angiography and was effectively treated by intravascular embolization.
Conclusions. For unexplained upper gastrointestinal bleeding, the possibility of duodenal Dieulafoy lesion should be considered. A combination of multiple diagnosis and treatment methods can improve the success rate of diagnosis and treatment when a single test or treatment method cannot provide definitive diagnosis or effective treatment.
Management of thrombocytopenia-associated multiple organ failure: plasma infusion vs plasma exchange
Authors: Çeleğen Mehmet , Çeleğen Kübra
Published: December 2022

Background. Thrombocytopenia-associated multiple organ failure (TAMOF) causes a high ratio of mortality in pediatric patients. Only anticoagulants and profibrinolytic molecules can be replaced with plasma infusion (PI), while therapeutic plasma exchange (TPE) eliminates antifibrinolytic and thrombogenic molecules and charges inadequate anticoagulants and profibrinolytic molecules. This study aims to compare the efficacy of plasma exchange to plasma infusion in pediatric TAMOF patients.
Methods. Twenty-seven patients with TAMOF were included and the efficacy of PI and TPE was compared. The demographic data, admission laboratory values, Pediatric Logistic Organ Dysfunction (PELOD) scores before the beginning of treatment and PELOD at the end of treatment, and outcomes of groups were compared.
Results. Sixteen children were in the plasma infusion group, eleven children were in the plasma exchange group. The total mortality rate of all patients was 37%. The PELOD scores were significantly reduced on the 5th day of treatment in both groups and also PELOD scores were significantly higher on the 5th day of study in the non-survivor group (p: < 0.001). The fifth day of PELOD scores and ferritin had a significant effect on mortality (OR: 1.85, 95% CI: 1.02-2.69; p: 0.04, OR: 1.43, 95% CI: 0.97-2.03; p: 0.05). The overall mortality ratio was not different between TPE and PI groups (p: 0.12).
Conclusions. Although there was no difference in mortality rates in children who received plasma exchange compared to children who received plasma infusion, mechanical ventilation and length of pediatric intensive care unit (PICU) day were shorter in the TPE group. The small patient population may be the major cause for the lack of significant statistical difference.

Published: December 2022

Jagung adalah salah satu produk pertanian yang dihasilkan di Desa Curahnongko yang produksinya cenderung meningkat. Berdasarkan data BPS Jember, potensi desa tersebut untuk komoditi jagung cukup besar yaitu 11.802 ton yang dari luas tanam 1.685 Ha. Sebagian besar jagung dijual dalam bentuk jagung pipilan, dengan menyisakan limbah batang, daun, klobot dan tongkol jagung. Tongkol jagung merupakan limbah terbesar (30%) dari buah jagung. Apabila dikonversikan dengan jumlah produksi jagung pada tahun 2017, maka Desa ini berpotensi memberikan limbah tongkol jagung sebanyak ± 3.540 ton. Limbah tersebut terhitung sangat banyak sehingga sangat potensial jika ditransformasi menjadi sesuatu yang bermanfaat  secara tepat.  Limbah tongkol jagung belum dimanfaatkan masyarakat dan dibiarkan berserakkan di lahan-lahan kosong membentuk timbunan yang besar dan tinggi. Seiring waktu, tongkol jagung ini akan rusak dan busuk sehingga menimbulkan bau yang mengganggu lingkungan dan kesehatan. Oleh karena itu diperlukan solusi terhadap limbah tersebut agar tidak mengganggu lingkungan dan kesehatan, serta mengubah limbah menjadi produk yang bermanfaat dan bernilai ekonomi tinggi. Solusi yang ditawarkan untuk menyelesaikan permasalahan tersebut yaitu mengedukasi masyarakat tentang jumlah limbah tongkol jagung dan komposisi kimia, teknologi tepat guna dalam produksi pakan ternak dari tongkol jagung, serta melakukan perhitungan agribisnis dan pemasaran produk pakan ternak.

Authors: Hazrina Fadhillah , Purwiyanto Purwiyanto
Published: December 2022

Currently the electrification ratio in Banyumas Regency is around 79%. This means, of the 1.7 million residents of Banyumas Regency, only around 21% have not enjoyed PLN electricity. Those whose homes have not yet had electricity are on average residents who are on the slopes of the mountain slopes, and some residents in several groves in remote areas in Banyumas Regency which are very far from the PLN electricity network. This problem can be overcome by providing electrical energy by utilizing renewable alternative energy, one of which is micro hydro or pico hydro power plants on an individual or residential scale. Therefore, this research designed a simulation of a pico hydro power plant using a Pelton turbine which is expected to be able to provide benefits to the general public, this tool is equipped with remote monitoring using Google Firebase based on the Internet of Things which can be monitored via the Android application for monitoring Voltage, current and power use the INA219 sensor which has been programmed on Arduino Uno and Node MCU ESP8266. This tool uses a 12-24 Volt DC generator, produces DC electricity which is stored in a 12 Volt 5 Ah battery which is then converted using an inverter to become AC electricity. In this test using a 5 Watt AC lamp load, the battery voltage which was initially 12.6 Volts was reduced to 9.9 Volts, the lamp load was able to light up for 1 hour. In measuring the voltage and current, the generator produces an average voltage of 15.9 Volts and a current of 50.2 mA.

The experiment was conducted at Adami Tulu Agricultural Research Center (ATARC), Lume and Dugda Districts during the 2019 and 2020 main cropping seasons to identify adaptable and high yielder snap bean genotypes for East Shewa Zone and similar agro ecologies. Ten snap bean genotypes were used as planting material. The experiment was laid down in Randomized Complete Block Design (RCBD) with three replications. The AMMI model shows that the environment accounted for 40.93%, GXE 31.79%, and genotype 12.70% of the total variation. The high percentage of the environment indicates that the major factor influencing the yield performance of snap beans is the environment. The first two IPCAs are the most accurate model that could predict the genotype’s stability and explained by IPCA-I (53.10%) and IPCA-II (21.1%) of GEI. This result revealed that there were differential yield performances among snap bean genotypes across testing environments due to the presence of GEI. According to stability parameters (ASV, and GGE Biplot) and mean yield results revealed that G-24 and G-12 genotypes are the most stable genotypes across test locations. Therefore, G-24 and G-12 were proposed as candidate genotypes for possible release.

Pergerakan orang antarwilayah dapat mempengaruhi penyebaran virus dalam wilayah tersebut. Status zona pandemi di wilayah menjadi salah satu faktor analisis risiko stasiun sebagai klaster penularan dan risiko penumpang tertular COVID-19 di kereta. Tujuan penelitian ini adalah untuk mengetahui tingkat risiko penyebaran virus ketika menggunakan perjalanan dengan moda kereta api dan kebijakan yang dapat dilakukan untuk mengurangi risiko penyebaran virus di stasiun kereta api. Metode penelitian yang digunakan adalah metode pengukuran risiko yaitu pengukuran potensi penyebaran COVID-19 di stasiun Kereta Api. Metode ini dilakukan dengan mengukur tingkat risiko penumpang Kereta Api tertular virus COVID-19. Metode pengukuran konsep risiko terkait dengan fenomena COVID-19 menggunakan pendekatan persamaan risiko dengan parameter Bahaya, Kerentanan, dan Kapasitas. Penelitian ini menggunakan studi kasus Stasiun Tugu Yogyakarta yang pada saat sebelum pandemi melayani sekitar 1.219 penumpang per jam sibuk. Pada saat pandemi, jumlah rata-rata penumpang per jam sibuk adalah sekitar 189 penumpang dengan berbagai kebijakan pembatasan yang dilakukan. Intervensi yang dilakukan dengan membatasi kerentanan orang (pembatasan jumlah penumpang) dan kerentanan ruang (penerapan pemanfaatan ruang agar lebih terbuka, tidak menumpuk, dan mengurangi kontak) serta meningkatkan kapasitas dengan penerapan protokol kebijakan kesehatan akan mampu mengurangi potensi risiko penyebaran virus COVID-19. Hasil penelitian menunjukkan bahwa status wilayah merah memiliki risiko dua kali lipat dari status oranye. Status wilayah merah diharapkan menjadi dasar mitigasi kebijakan pembatasan jumlah penumpang yang diperbolehkan naik, peningkatan protokol COVID-19 yang semakin ketat, seperti kebijakan bagi penumpang untuk diwajibkan swab atau tidak, penggunaan alat pendeteksi awal COVID-19, dan pemisahan kereta bagi penumpang yang berasal dari stasiun wilayah berstatus merah. Kebijakan pengurangan jumlah penumpang pada tiap perjalanan kereta mencapai 50% dari jumlah maksimal penumpang sudah sesuai dengan Kajian Manajemen Risiko dalam studi ini karena akan mengurangi risiko lebih dari sampai 75% dibandingkan dengan jumlah penumpang maksimal

Sertifikat merupakan sebuah bentuk penghargaan yang didapat seseorang setelah menyelesaikan suatu uji kompetensi atau pembelajaran tertentu. Sertifikat harus dibuat dan disimpan dengan metode dan keamanan yang baik untuk mencegah terjadinya perubahan isi atau bahkan pemalsuan. Teknologi blockchain merupakan teknologi yang memungkinkan proses penyimpanan yang aman dengan ongkos yang rendah. Keamanan terjamin karena semua orang bisa mengambil bagian untuk menyimpan data dengan ledger yang terdistribusi. Berdasarkan hasil penelitian dan perancangan sistem yang dibuat dapat disimpulkan bahwa proses pembuatan teknologi blockchain sebagai media penerbitan sertifikat dan validasinya dapat dibuat menggunakan program milik Ethereum yaitu Geth dan penyimpanan data menggunakan smart contract yang diterbitkan pada jaringan blockchain. Hasil dari pengujian reliabilitas terhadap sistem menunjukkan bahwa bahwa sistem berhasil memproses 200 transaksi dalam waktu kurang lebih 8 detik. Untuk pengujian skalabilitas didapatkan estimasi 10 juta blok membutuhkan kapasitas penyimpanan sebesar 22,6 GB untuk menjadi node atau miner pada jaringan blockchain ini.

 

Abstract

A certificate is a form of appreciation that a person receives after completing a certain competency or learning test. Certificates must be created and stored with good methods and security to prevent changes in content or even forgery. Blockchain technology is technology that allows secure storage processes at a low cost. Security is guaranteed because everyone can take part in storing data with a distributed ledger. Based on the results of research and design of the system, it can be concluded that the process of making blockchain technology as a media for issuing certificates and validation can be made using Ethereum's proprietary program Geth and data storage using smart contracts issued on the blockchain network. The results of the reliability testing of the system indicate that the system successfully processed 200 transactions in approximately 8 seconds. For scalability testing, it is estimated that 10 million blocks require a storage capacity of 22.6 GB to become a node or miner on this blockchain network.

Komunikasi verbal adalah komunikasi umum digunakan sebagai sarana dalam memberikan informasi kepada orang lain. Disamping itu, untuk berkomunikasi dengan tuna rungu serta tuna wicara sarana komunikasi dapat melalui bahasa isyarat. Indonesia telah memiliki sistem bahasa isyarat yaitu Bahasa Isyarat Indonesia atau Sistim Isyarat Bahasa Indonesia (SIBI). Aplikasi pengenalan dan pembelajaran SIBI yang ada pada saat ini berupa aplikasi yang terikat pada platform. Aplikasi beserta proses pengenalan menjadi satu sehingga memiliki kebergantungan yang cukup tinggi. Penelitian ini bertujuan mengembangkan platform cloud sebagai backend untuk pengenalan gerakan tangan, sehingga memudahkan pengembang untuk membuat aplikasi pengenalan SIBI. Platform tersebut memiliki kemampuan untuk mengenal gerakan tangan yang diperoleh dari data sensor Myo Armband. Aplikasi yang berada sisi frontend dapat menggunakan fitur platform melalui Application Programming Interface (API) yang disediakan. Penelitian ini juga membangun aplikasi permainan edukasi yang menggunakan platform cloud tersebut sebagai implementasi dari penggunaan platform. Hasil pengujian terhadap platform yang dilakukan menghasilkan kemampuan pengenalan secara real-time dari satu atau lebih client secara simultan.
