Kaffah , Bagus Enggar Tiasto Department of Informatics, Faculty of Science and Technology Sunan Gunung Djati State Islamic University Bandung Abstract SSO (Single Sign-On) is an authentication service that allows users to use a set of credential data to access multiple applications. SSO can be implemented by using many protocols, one of which is SAML (Security Assertion Markup Language). SAML is a framework or open message delivery standard that allows identity and security information to be shared with each entity. The data is shared by sending it over a network which allows someone who is not responsible to capture the data. And if the security data from this SSO has been obtained it will have fatal consequences considering that the data can be used to access all applications in the SSO entity. Then we need a reliable data security method so that it is not easy to read by an attacker even with a dictonary attack technique. In this study data security is performed using the RC4 algorithm (Rivest Cipher 4), and it is expected to secure credential data that is exchanged within the SSO entity.

Computerized adaptive test based on sugeno fuzzy inference system Wrastawa Ridwan, Ifan Wiranto, Rahmat D.R. Dako Electrical Engineering Department, State University of Gorontalo Abstract Along with the development of information and communication technology, assessment of student learning outcomes is no longer carried out in the form of written examinations, but rather carried out with a Computerized Adaptive Test (CAT). CAT consists of five main components, namely item bank, starting point, item selection, grading, and item completion point. CAT is adaptive because it allows the items given are selected according to the ability of students. Therefore, the CAT needs a method to estimate student ability. This research aims to design a Sugeno Fuzzy Inference System (SFIS) to estimate student ability. This fuzzy system consists of twelve IF-THEN rules, with four inputs, namely the students answer, the probability of students being able to answer correctly, the level of difficulty and discrimination of the questions. The output is an estimated ability, divided into five levels, namely very low, low, average, great, and excellent. Fuzzy system simulation is performed on linear algebra course with multiple-choice questions. The test will stop if the estimated value of the students ability does not change from the previous item. The simulation results show that the SFIS can estimate the ability of students by working on a maximum of six items each subject.

Harmonic Evaluation of Plug-In Electric Vehicle on Distribution Network System Kevin Gausultan Hadith Mangunkusumo (a), Joko Hartono (a), Putu Agus Aditya Pramana (a) PLN Research Institute Abstract The significant development of plug-in electric vehicle (PEV) is a challenge for distribution networks. The PEV charger is an electronic power device that generates large amounts of power over a period of time to charge EV battery. In addition, the EV on board charger (OBC) also produces harmonics due to the process of converting AC grid voltage to DC voltage. Converter as OBCs main device is a source of harmonics which directly connected to the distribution network. In this study, harmonics from single OBC, multiple OBC and PEV penetration scenario were evaluated and compared with the SPLN standard D5.004-1: 2012. From the study results, THD injected to the distribution network is influenced by the percentage of the base load and PEV penetration. The worst possible condition is occurred under low load conditions while high PEV penetration happens. From the simulation results using the distribution network model especially in residential area, the low base load scenario (10.47%) and the high PEV penetration (90.01%) is generating TDD 6.59% and THDv 2.61%. Therefore it is known that the harmonic effects generated by PEV charging to the distribution network still meet SPLN D5.004-1: 2012.

The disadvantage of an electric bicycle is the distance that it cannot be far and the charging time is quite long, so that sometimes it still requires energy from humans to pedal the bicycle when the electrical energy in the battery is exhausted. So it need a system that can refill the electric bicycles battery while it is being used. This research will design a system that will regenerate the wheels rotation of a bicycle into electrical energy, especially when it is moving and using human energy. By using a 6V DC mini generator mounted on the wheels, and the charging controllers to the battery, when farther the bike rotates, the greater the electrical energy it will generate, so the battery can be re-charged and increase the mileage of the bicycle compared to the built-in battery system.

Technical and Economical Evaluation of Distribution Transformer with Amorphous Metal Core in Indonesia Brian Bramantyo Satriaji Dwi Adiputro Harsono, Joko Hartono, Nur Widi Priambodo, Handrea Bernando Tambunan, Dhandis Rito Jintaka, Kemas M. Tofani H.S., Muhammad Ridwan PLN Research Institute Abstract High efficiency electrical equipment usage is an alternative solution to support carbon emission reduction in Indonesia. In this research, new distribution transformer design using amorphous metal core (AMDT) was evaluated by conducting laboratory testing and field installation. According to the laboratory test result, AMDT had 60.91 – 67.35% smaller no-load loss but 0.58 – 9.79% higher load loss compared to national standard requirement (although the load loss value of AMDT was within total losses tolerance). One AMDT sample failed during impulse test which should be followed up further by conducting insulation testing and design evaluation. Since the AMDT sample used 5-legged core design, the weight of the AMDT was heavier than conventional cold rolled grained oriented (CRGO) silicon steel transformer; thus, the construction planning and design should be re-evaluated for AMDT installation. According to total cost calculation based on life cycle approach by using obtained data and related assumptions, it was found that AMDT would potentially give higher economic benefit than conventional CRGO silicon steel transformer when the load factor (LF) is below 79% for 100 kVA AMDT, below 78% for 50 kVA AMDT, and below 68% for 25 kVA AMDT.
