Implementasi Group Blind Digital Signature dalam Sistem E-voting Pemilihan Kepala Daerah

Pemilihan kepala daerah di Indonesia masih bersifat konvensional sehingga kurang efektif dan masih banyak kekurangan dan kesalahan akibat human error terutama dalam hal perhitungan suara. dibutuhkan sistem pemungutan suara yang dapat meminimalisir human error tersebut. E-voting merupakan salah satu solusi pengganti system voting konvensional, dalam e-voting peran manusia tergantikan dengan komputer terutama dam hal perhitungan suara, sehingga kesalahan dalam perhitungan suara dapat diminimalisir. Untuk menjaga kerahasiaan sistem e-voting ini menggunakan kriptografi yang berupa group blind digital signature yang merupakan variasi dari tanda tangan dijital yang dibangun berdasarkan algoritma RSA. Melalui enkripsi data, sistem ini mengamankan data kandidat yang telah dipilih oleh pemilih, sehingga kerahasiaan pilihan tetap terjaga. dalam penelitian sistem e-voting yang dilaksanakan ini, group blind digital signature digunakan pada saat pengiriman data dari instansi yang ada dalam proses pemilihan kepala daerah untuk otentifikasi data yang dikirimkan

The Schematic Structure of North Sumatran Folktales

This research aimed to analyze the schematic structure of North Sumatran folktales by using the Systemic Functional Linguistic approach and the concept of the narrative genre. Descriptive qualitative research methods were used. The data were collected through documentation and the data were analyzed using the interactive model proposed by Miles, Huberman and Saldana. The researchers asked English university students to write North Sumatran folktales based on the narrative genre. The research data were in the form of clauses taken from these writings. In analyzing the data, the researchers labeled the clauses based on experiential function and the text was then identified by schematic structure of the narrative genre.

Estrategia de precaución de la práctica de riesgos morales en los seguros agrícolas en Indonesia: un enfoque de la metodología de los sistemas blandos

[EN] This paper uses Soft Systems Methodology (SSM) to formulate strategies to prevent moral hazard acts in agricultural insurance in Indonesia. Agricultural insurance takes place, mainly, through Rice Crop Insurance and Cattle Insurance. Generally, the strategies that can be performed to minimize moral hazard practice in agricultural insurance programs are: developing the capacity of human resources, improving field communication, enforcing penalties, institutional strengthening, and adding new products through Islamic agricultural insurance. Specifically, this paper proposes that the prevention of moral hazard practices can be done by implementing Islamic agricultural insurance systems with the concept of risk-sharing instead of risk transfer.[ES] Este trabajo utiliza Soft Systems Methodology (SSM) para formular estrategias para prevenir el riesgo moral en los seguros agrícolas en Indonesia. El Seguro de Cosecha de Arroz y el Seguro de Ganado son los más utilizados. Las estrategias son: desarrollo de la capacidad de los recursos humanos, mejora de la comunicación sobre el terreno, aplicación de sanciones, fortalecimiento institucional e incorporación de nuevos productos a través del seguro agrícola islámico. En concreto, se propone que la prevención del riesgo moral puede realizarse mediante sistemas de seguros agrícolas islámicos basados en el concepto de compartir el riesgo en lugar de transferirlo.The authors thank Lembaga Pengelola Dana Pendidikan (LPDP), Riset Inovatif Produktif (RISPRO) Tata Kelola/Kebijakan No. PRJ-120/LPDP/2019, the Ministry of Finance of the Republic of Indonesia, the Regional Development Planning Board (BAPPEDA) Aceh, Agriculture and Plantation Department (DISTANBUN) Aceh, Animal Husbandry Department (DISNAK) Aceh.Fadhil, R.; Yusuf, MY.; Bahri, TS.; Maulana, H.; Fakhrurrazi, F.

The Use of Pozzolanic Material for Improving Quality of Strontium Liquid Waste Cementation in Saline Environment During Nuclear Waste Immobilization Process

This research was conducted to study the use of artificial pozzolanic material (portlandpozzolana cement or PPC) and natural pozzolanic material (fly ash) to improve quality of strontium liquid waste cementation in saline environment during nuclear waste immobilization process.The portland cement was mixed with 10 v/0 strontium liquid waste (water containing 65 ppm Sr(II)), 0.3 water-cement ratios (w/c), 20 v/0 fly ash, -40 mesh to -60 mesh sand. Similar process was performed using commercial portlandpozzolana cement (PPC). Compressive strength test after cured the block cements for 28 days was performed using pressing machine. To study leaching rate test, 10 ml contaminated saline water was sampled from immersion of cement block with 1 liter saline water for 21 days. Hitachi Zeeman 8000 Atomic Absorption Spectrophotometer was used for analyzing leaching rate test.All cement blocks showed the results above than 2.5 N/mm2 of IAEA standard during strength test. The fly ash showed 103-105% higher strength test than commercial PPC in all grain size. But the fly ash showed 4-5% less durable during leaching rate than commercial PPC during 21 days immersion. All the cement blocks showed the results above than IAEA standard during leaching rate test.The addition of natural pozzolanic material (fly ash) could improve the strength of strontium liquid waste cementation. In other hand, the artificial pozzolanic material could improve the durability from leaching rate of strontium liquid waste cementatio

Antibiogram of pharyngeal isolates of children with pharyngotonsillitis in a specialist hospital in Gusau, North-Western Nigeria

Pharyngotonsillitis is one of the common childhood infections caused by bacteria in 30 to 40% of cases. Bacterial causes are important due to the non suppurative sequalae caused by Streptococcus pyogenes and also associated complications. These microorganisms undergo constant changes and antibiotic resistance have been reported. Objective: To document organisms isolated from throat swab microscopy and culture with their antibiotic susceptibility pattern in children diagnosed with pharyngotonsillitis. Methodology: This was a retrospective analysis of throat swabs microscopy, culture and sensitivity results of children aged 0-13 years with a diagnosis of pharyngotonsillitis over a four-year period. Results: Of the 144 results reviewed; 120 samples yielded 122 isolates, giving a culture positive yield of 83.3%. Males were 81 (56.2%) with a M:F ratio of 1.3:1. Majority of the children were under fives (58.3%). Gram positive organisms were 118 (96.7%), with Streptococcus pyogenes being the commonest organism isolated (79.5%), followed by Staphylococcus aureus (13.9%). Gentamicin (85.0%), Ofloxacin (64.2%) and Augmentin (51.7%) had the highest susceptibility rate, while the least was seen with Cefixime, Tetracycline, Levofloxacin and Netillin. Streptococcus pyogenes and Staphylococcus aureuswere susceptible to Gentamicin and Ofloxacin, while all the Streptococcus pneumoniae were susceptible to Gentamicin. Multi drug resistance was seen with Providencia spp and Serratia marcescens. Conclusion: Streptococcus pyogenes was the commonest organism and Gentamicin, Ofloxacin and Augmentin were the antibiotics with the highest susceptibility. Gram negative organisms display high rate of multidrug resistance. Gentamicin could be considered as an option or an adjunct in the treatment of pharyngotonsilliti

Pixel frequency based railroad surface flaw detection using active infrared thermography for Structural Health Monitoring

Abstract With rapid increase in operation and development of high-speed trains, inspection of railroad surface flaws has become an important aspect for safe and reliable operation of rail network. Non-destructive testing using active infrared thermography has been useful in determining the structural health of different structures with additional benefit of robustness in overall inspection system. This study is based on detection of artificial surface flaws on an in-service railroad. Transverse and longitudinal flaws of various dimensions were machined on rough and smooth rail surface. The railroad surface was thermally stimulated to a temperature equivalent to practical conditions. Emitted radiations from rail surface were captured by an infrared camera to detect cracks. Results show a comparison between the surface flaws on rough and smooth rail surface. Subsequently, raw infrared images were post-processed by statistical image improvement to quantitatively analyse the results. Significant change in the frequency distribution of pixel intensity is observed as the flaw size and depth changes giving a clear quantification of crack topology. A comprehensive and inexpensive solution for damage diagnosis will be offered to railway authorities for Structural Health Monitoring (SHM) and NDT by the proposed framework
