Microgrids are a group of loads and distributed power generation sources acting as a single entity to provide power to the user or the grid. Since a Microgrid is a system of systems, this leads to an operability problem for local management and an interoperability problem for remote management. Operability and interoperability problems are solved by Data Acquisition and Control Systems (SCADA). There are several commercial platforms for the development of SCADA systems, being most of the time very expensive for the average user and even many universities. Therefore, this paper presents the design and implementation of a SCADA Web based on open-source software for experimental microgrids to allow the management of Microgrids remotely through the web. The Web-based SCADA system was developed for the Renewable Energy Laboratory (LabDER) of the Universitat Politècnica de València. An OMRON CPU CJ2M PLC was linked to a remote MYSQL database. A user interface was programmed using JAVA, and PHP languages perform operations and take data for the web-based SCADA system. The implemented SCADA system allowed monitoring and limited control of the LabdDER microgrid remotely, showing it to be an effective solution for Microgrids remote management.

The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.

a b s t r a c tThis study aims to design a new system and method of application program Al-Faraidh as a medium of learning fiqih mawaris in MAN Model Banda Aceh. This research uses qualitative descriptive method, that is by collecting data through interview with fiqih teachers and literature study. The study of jurisprudence is difficult to achieve the expected competence, mawaris calculation is also still done manually. Students tend to be less interested in learning fiqih mawaris because it is considered too difficult. Therefore it is necessary to design an application program as a learning medium that facilitates and attracts students' attention. The design of the web-based application program can process the data muwaris (person who left the heirs), data of heirs along with his position against muwaris, heirs, muwaris reports, and recapitals report on the division of inheritance. The application program is expected to be an effective solution of the problem, thus simplifying the process of calculating the inheritance, especially in the process of learning.Keywords:Applications Alfaraidh, Mawaris, Media Learning a b s t r a kPenelitian ini bertujuan merancang sebuah sistem dan metode baru berupa program aplikasi Al-Faraidh sebagai media pembelajaran fiqih mawaris di MAN Model Banda Aceh. Penelitian ini menggunakan metode deskriptif kualitatif, yaitu dengan mengumpulkan data melalui wawancara dengan Guru Fiqih dan studi pustaka. Pembelajaran fiqih mawaris sulit mencapai kompetensi yang diharapkan, perhitungan mawarisnya juga masih dilakukan secara manual. Siswa cenderung kurang tertarik mempelajari fiqih mawaris karena dianggap terlalu sulit. Oleh karena itu diperlukan sebuah rancangan program aplikasi sebagai media pembelajaran yang memudahkan dan menarik perhatian siswa. Rancangan program aplikasi yang berbasis web tersebut dapat mengolah data muwaris (orang yang meninggalkan harta waris), data ahli waris beserta kedudukannya terhadap muwaris, harta waris, laporan muwaris, dan laporan rekap hasil pembagian harta waris. Program aplikasi tersebut diharapkan dapat menjadi solusi yang efektif dari permasalahan tersebut, sehingga mempermudah proses perhitungan harta waris, khususnya dalam proses pembelajaran.Kata Kunci:Aplikasi Alfaraidh, Mawaris, Media Pembelajaran

Abstract Industrial automation and control systems (IACS) play a key role in modern production facilities. On the one hand, they provide real-time functionality to the connected field devices. On the other hand, they get more and more connected to local networks and the internet in order to facilitate use cases promoted by “Industrie 4.0”. A lot of IACS are equipped with web servers that provide web applications for configuration and management purposes. If an attacker gains access to such a web application operated on an IACS, he can exploit vulnerabilities and possibly interrupt the critical automation process. Cyber security research for web applications is well-known in the office IT. There exist a lot of best practices and tools for testing web applications for different kinds of vulnerabilities. Security testing targets at discovering those vulnerabilities before they can get exploited. In order to enable IACS manufacturers and integrators to perform security tests for their devices, ISuTest was developed, a modular security testing framework for IACS. This paper provides a classification of known types of web application vulnerabilities. Therefore, it makes use of the worst direct impact of a vulnerability. Based on this analysis, a subset of open-source vulnerability scanners to detect such vulnerabilities is selected to be integrated into ISuTest. Subsequently, the integration is evaluated. This evaluation is twofold: At first, willful vulnerable web applications are used. In a second step, seven real IACS, like a programmable logic controller, industrial switches and cloud gateways, are used. Both evaluation steps start with the manual examination of the web applications for vulnerabilities. They conclude with an automated test of the web applications using the vulnerability scanners automated by ISuTest. The results show that the vulnerability scanners detected 53 % of the existing vulnerabilities. In a former study using commercial vulnerability scanners, 54 % of the security flaws could be found. While performing the analysis, 45 new vulnerabilities were detected. Some of them did not only break the web server but crashed the whole IACS, stopping the critical automation process. This shows that security testing is crucial in the industrial domain and needs to cover all services provided by the devices.

This study reports on the use of an open-source software for sign language learning and (self-)assessment. A Yes/No vocabulary size test for Swiss German Sign Language (Deutschschweizerische Gebärdensprache, DSGS) was developed, targeting beginning adult learners. The Web-based test, which can be used for self-assessment or placement purposes, was administered to 20 DSGS adult learners of ages 24 to 55 (M = 39.3). The learners filled out a background questionnaire, took the Yes/No test tests, and filled out a feedback questionnaire. The comments provided by the learners about the suitability of the Web-based DSGS vocabulary self-assessment instrument provided concrete feedback towards improvement of the system.
