Abstract

The development of the Internet of Vehicle (IoV) is overgrowing toward driving comfort, safety, and efficiency. Autopilot or a car without a driver is one implementation of IoT. To run the full function of IoV, a reliable communication network is needed because the risk will be substantial due to the low quality of network infrastructure services. In this research, we will analyze the quality of network infrastructure services. The analysis can be done through two approaches: direct measurement in the field using a GPS Tracker-based system and modeling using the mathematical function of transmit power of mobile communication transmitting devices. The test is carried out in a specific area with a sample of high traffic and low-density areas. This method was chosen to find the right pattern in measuring the quality of communication network services. The tests carried out produce dynamic data on service quality in certain areas. For areas of low density, the service quality tends to be below as well, and many areas without signal are found, while for areas with high density, the quality of service is found to be good, but network overload conditions often occur.

Abstract

The objective of this work is to clone flanking DNA derived from Tn-5 mutagenesis of wild type strain Xanthomonas axonopodis pv. glycines as first step to clone and to identify the gene involved in pathogenicity mechanism. We have localized the flanking DNA fragment from a nonpathogenic mutant of Xag M715. Southern hybridization analysis using 2.8 kb EcoRI from pYR103 as a probe showed that the fragment is located within 2.0 kb PstI fragment. A 0.7 kb flanking DNA was amplified using inverse PCR technique, and inserted into pGEM-T Easy vector generating a 3.7 kb recombinant plasmid (pAA01). Southern hybridization analysis of the wild type (YR32) with pAA01 as a probe indicated a hybridization signal located at approximately 3.0 kb PstI fragment. DNA sequence analysis revealed that the DNA fragment has a 64% identity to a vir gene of Bacillus anthracis.

Abstract

A rapid polymerase chain reaction (PCR)-based procedure was developed for detection of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule disease on soybean. A set of primers was designed from partial sequence of the pathogenicity gene of X. axonopodis pv. glycines strain YR32. Specific PCR product of 490 base pairs was produced from strains of X. axonopodis pv. glycines originally from Indonesia as well as from Taiwan. No other pathovars and bacterial species among those tested showed amplification product under optimized PCR conditions. Shaking infected soybean leaves in phosphate buffer saline during six hours was proved to be an essential in order to increase cell number of the bacterial. The procedure was applicable and reliable for detecting of pathogens in infected plant materials. The procedure was proved to be more effective than that of conventional detection and could be of great help for monitoring of pustule bacterial disease in the soybean fields. Key words: Xanthomonas axonopodis pv. glycines, bacterial pustule disease, rapid detection, PCR, specific primer

Geminivirus infecting pepper: symptom variation and transmission study Infection of geminiviruses has been reported to cause signz3cantyield loss on various crops. Polymerase chain reaction was able to detect geminivirus infection on pepper samples around Bogor and Cipanas, West Java. Symptom variation and transmission of the geminivirus infectingpepper was studied using five solanaceae plants with three dzgerent transmission mannec i.e. mechanical inoculation, side grafirng, and insect vector. The transmission study showed that mechanical inoculation was not able to transmit the eminivirus, while side grafting and insect vector, Bemisia tabaci, caused infection with symptoms varies from yellow mosaic, leaf curl leaf distortion, to stunting of the plant. Higher infection was observed on pepper var. Hot Chilli through B. tabaci (8009) and side grafting (71.4%) than those on chilli pepper and tomato. DNA fiagment of - 1.7 kb was amplified wing PCRfim those plants showing symptoms, but no DNA fiagment was observedfrom symptomless eggplant and tobacco var. White Burley. Thus it can be concluded that the last two kina3 ofplants were resistant to the geminivirus infectingpepper.

Abstract

Kota Banyumas dahulu ibu kota karesidenan Banyumas, menjadi pusat pemerintahan HindiaBelanda. Pada pusat pemerintahannya diutara alun-alun terdapat pendapa yang di sakralkan PendapaSi Panji, dibangun Tumenggung Yudanegara II sekitar tahun 1743.Pendapa ini bermodel ”JogloTajug”, sebutan lokal yang ganjil, tidak dikenal pada bentuk arsitektur tradisional Jawa. Disini dicaribagaimana bentuk “Joglo Tajug” itu dan apa penyebabnya ? Karena letaknya diperbatasan Jawa Barat,dan di Banyumas terjadi akulturasi Jawa dan Sunda. maka diduga ini percampuranarsitekturtradisional Jawa dengan Sunda ,atau mungkin adanya pengaruh lain dimasa lalu. Disini dibuktikan halitu dengan meneliti Pendapa Si Panji, hasil penelitiannya di kaji dengan teori Sejarah, BudayaBanyumasan, arsitektur tradisional Jawa, dan Sunda. Didapatkan bentuk Pendapa Si Panji berupaatap Tajug yang seharusnya sama sisi dipaksakan diatas denah Joglo yang empat persegi panjangsehingga menjadi bentuk yang ganjil, dan bentuk Joglo Tajug diduga tercipta sebagai protes alaBanyumasan terhadap raja Jawa masa itu.Kata kunci : Javanese Banyumasan, Joglo, Tajug

Abstract

Peranan Information and Communnication Technology (ICT) telah banyak diketahui adalah untuk efisiensi, efektivitas dan transparans. E-Democracy di Indonesia belum berjalan dengan baik. ICT diharapkan dapat merubah pola pikir dalam melakukan pesta demokrasi, transparansi yang ditawarkan ICT bisa mengurangi kecurangan yang banyak dilakukan selama ini. Stakeholder sangat memengaruhi sukses atau tidaknya pelaksanaan e-Democracy di Indonesia. Kekuatan stakeholder dalam mensukseskan perlu adanya sosialisasi sehingga mempunyai power dalam mewujudkan e-Democracy. Masing-masing aktor dalam stakeholder bisa mengubah situasi dan kondisi tercapainya e-Democracy yang baik. Apabila dilakukan perubahan dari voting tradisional ke e-voting, maka peranan local administrasi sangat berpengaruh.

Abstract

In the current condition of society that is critical in responding to everything, more public services are needed professional, effective, simple, transparent, timely, responsive. Efforts to improve the quality of public services cannot be separated from service evaluation. In order to improve the quality of public services, the Directorate General of Informatics Applications of the Ministry of Communications and Informatics established the Public Service for Aduan konten at the Directorate of Information Application Control (PAI) as a pilot project. So to evaluate the quality of public services, a bureaucratic reform program is carried out at the PAI Directorate through efforts to develop a zone of territorial integrity free from corruption and a clean bureaucratic area to serve. One of the evaluations carried out is for measuring service performance as mandated in the Regulation of the Minister of Administrative Reform Number 14 of 2017 concerning the Community Satisfaction Survey (SKM) on the Implementation of Public Services. This study aims to determine the service quality of the Content Complaint website using the e-Govqual method, while the IPA and heuristic evaluations are to determine the attributes that are priorities for improving service quality, as recommendations to public service providers for Aduan konten. To assess the service quality of the content complaint website, 6 dimensions and 21 e-Govqual attributes are used. Of the 300 respondents who were used as research samples, this study shows the results of the analysis of the level of conformity of the 6 dimensions are 98.03% (<100%) meaning that the public services provided by the Aduan konten website are not satisfactory to users or still not in accordance with user expectations. The result of the average value of the gap between expectations and performance shows the number -0.05 or < 0. With this gap, it can be said that the quality of public service performance of Aduan konten perceived by the public still does not meet what is expected. Attributes that need improvement are those in quadrant A (3 attributes) and quadrant C (8 attributes). Recommendations are given based on the literature/theory for attributes that need to be improved to improve the quality of public services for Aduan konten.
