<![CDATA[In recent years, human computer interaction has been attracted many researchers and applied in various applications. In order to understand human language, the computer is required to learn human language grammar, one of the languages is Bahasa Indonesia. Left-corner parsing algorithm is used extensively to check English grammar. However, only several implementations are found in Bahasa Indonesia. By combining Left-Corner Parsing algorithm with stemming algorithm, to reproduce basic word and word type before the sentence is parsed according to production rules defined, this article discusses Bahasa Indonesia sentence pattern checking system testing for four single sentence patterns, i.e., Subject-Predicate, SP-Object, SP-Adverb, and SPOA. The testing resultshows the accuracy of sentence pattern recognition of 95.3%.]]>

<![CDATA[Along with the development of internet technology, recipes can easily be obtained from various sources, such as websites, mobile applications, and social media. The variety of recipes that available in various media still have one disadvantage: it can not accommodate user preferences. In this kind of problem, the role of a Decision Support System (DSS) is needed by people who actively cook using recipes in daily cooking activities. DSS recommendations for recipes can be built by using Simple Additive Weighting (SAW) algorithm. The variables chosen as criteria for recipe recommendations are duration of cooking, level of complexity, and calories. The ranking consistency test aims to see if there is a ranking reversal (the first ranking is swapped with the latest ranking) when there is a change in the number of recipes (alternatives). The purpose of this research is to find out the reliability of the SAW algorithm in the issue of recipe recommendations. The ranking consistency test result shows consistency of 100% and there is no rank reversal (last recommendation becomes first recommendation) for this case.]]>

<![CDATA[The development of a region is related to the process of procurement of goods/services. Good and quality service will improve the image of the procurement of goods/services in serving the procurement of goods/services in Sidoarjo Regency. For this reason, measurement of service satisfaction level is needed to determine the quality of services that have been provided so far. The purpose of this study is to determine the distribution of user satisfaction based on five dimensions of service quality,i.e., tangibles, reliability, responsiveness, assurance, empathy with two variables of reality and expectations, and knowing things that hinder the tender process. Retrieval of data is done with two kinds of internal and external questionnaires using simple random sampling method. Overall, 100% of respondents express satisfaction but there are some things that need to be improved. The results of the study from the external side show a very large gap in the completeness aspect of the electronic pre-tender process of 5.60%, while the biggest internal gap is the aspect of tender planning, which is 6.97%. Dimensions that need to be prioritized for improving the quality of service to reduce the gap are assurance dimension from the external and responsiveness from the internal.]]>

<![CDATA[The quality of lighting in a room will affect visual comfort. It is determined by light beam that hits observer’s eyes generating a specific response. Meanwhile, the indicator that represents visual comfort is glare, especially discomfort glare. Glare index in a room, one of them, is stated by Unified Glare Rating (UGR) value affected by the ratio of glare source’s luminance and background in a specific solid angle and position between observer and luminaire. As a result, it is needed to conduct an assessment to know glare potency in a room. The popular method measuring UGR is by analyzing pixel value from High Dynamic Range (HDR) image captured by 180-degree camera. At the same time, the implementation of 360-degree camera in assessing photometry has also been developed. However, the implementation is not been applied to measure glareyet. Therefore, this paper is aimed to implement 360-degree camera determining UGR value of HDR image. It is conducted by comparing the UGR value to 180-degree camera image. The result shows the significant irrelevance of both cameras. Statistical analysis on Lmean and Lstd found that the coefficient of determination is less than one and Root Mean Square Error(RMSE) is bigger than 0.1, while F-test and T-test results are less than 0.05. The value of Coefficient Variation ( CV) 180-degree camera is bigger than 360-degree camera which stated the data of luminance value is more spread out. It shows that the use of 360-degree camera with per-pixel analysis on HDR image to measure glare is not appropriate.]]>

<![CDATA[The use of radio spectrum in L-to-X bands is currently very diverse, with various types of devices. Therefore, an antenna with good response on very wide spectrum is expected to be a solution for diverse devices. By widening the antenna bandwidth that is applied to the ultra-wideband (UWB) communication, it is expected to be able to meet wireless communication needs on other bands or frequencies. The UWB antenna has the fractional bandwidth of at least 20% of its center frequency. This paper proposes an attempt to widen the bandwidth of planar UWB antenna with a circular patch (resonator) using coplanar waveguide (CPW). The study was conducted by the phased modification scenario using tapered line and spline-curved ground plane method. This method achieved a UWB antenna with fractional bandwidth of 145.57% (with a testing limit up to 12 GHz frequency) in the size of 40×50 mm2. At the testing bandwidth (L-X band), the basic form antenna (Model A) has a total bandwidth achievement of 39.36% (triple-band); the first antenna modification using tapered line at the feed line (Model B) has total bandwidth achievement of 83.09% (dual-band); and the last antenna modification using the tapered line (from the first modification) with the spline-curved ground plane addition (Model C) has total bandwidth achievement of 91.91% (single-band).]]>

<![CDATA[Nowadays, technology is growing and helping the human work. One of those technologies is object mapping or localization in an indoor environment. The technology is often used to determine position is Global Positionig System (GPS). However, GPS signal is difficult to receive when the device is inside a room or building. Therefore, in this research Indoor Localization is implemented at Telkom Institute of Technology Purwokerto with Wireless Sensor Network (WSN) which uses ZigBee as communication protocol. One of indoor localization stages is distance estimation, which in this case, is carried out using Received Signal Strength Indicator (RSSI) by grouping the value of Path Loss Exponent (PLE) based on room characteristics (clusters). Some methods for position estimation based on number of reference nodes are trilateration and multilateration methods. From the measurement results, the distances estimation with PLE clusters has an error of 0.534 meters and PLE without clusters has an error of 0.903 meters. For accuracy estimation, the best position is obtained on PLE cluster multilateration that has the value of 0,714 meters for Mean Square Error (MSE) and 1.2 meters for the lowest value MSE at trilateration without PLE clusters. The computational time of the four methods (multilateration without PLE clusters, trilateration without PLE cluster, multilateration with PLE clusters, and a trilateration with PLE clusters) are almost identical, between 8.72 to 8.75 second.]]>

<![CDATA[Quadcopter has nonlinear dynamics that require a robust controller to be able to fly stably. This paper uses a nonlinear controller, namely Sliding Mode Control (SMC). SMC has advantages such as robust from disturbance and uncertainty of parameters and ability to maintain stability, even when the dynamics model is not precise. The simulation compares the reliability of conventional SMC and modified SMC controls. Modified SMC control has the purpose of increasing the robustness of control system from disturbance and uncertainty. Based on the simulation, the modified SMC control has better reliability than conventional SMC. In conventional SMC control, the quadcopter response on the x-axis, to the reference position, has overshoots of 0.7 meters and 0.48 meters; and an undershoot of 0.45 meters. Then, the y-axis movement response has an overshoot of 0.3 meters and undershoots of 0.3 meters and 0.48 meters. The conventional SMC output of the z-axis movement has an undershoot of 1.75 meters, while on the modified SMC control, there are only overshoot and undershoot of 0.3 meters on the y-axis movement. Modified SMC control is more reliable than conventional SMC controls because the switching control of the modified SMC can adaptively change, according to the error caused by interference. The greater the uncertainty, the greater the error. A large error can increase the switching control frequency, so that the level of robustness will increase]]>

<![CDATA[Channel State Information (CSI) at the base stations obtained via the uplink trainingis an important factor in cellular and multiuser Multi-Input Multi-Output (MIMO) communi-cation networks. In massive MIMO cellular networks with pilot-based training, the most adopted approach is to employ the sameset of orthogonal training symbols in each cell. This is called the full-pilot reuse (FPR) scheme. In this paper, we consider the less-common but a more practical approach where each cell uses different sets of orthogonal training symbols and call this scheme as the Different Orthogonal Pilot (DOP) sequences. In particular, we focus on the downlink performance of massive MIMO networks with the Maximum Ratio Transmission (MRT) precoder at the base stations. The analysis is performed in the large system regime where the number of antennas at each base station and the number of users at each cell tend to infinity with a fixed ratio. We obtain a new expression for the Signal to Interference plus Noise Ratio (SINR) in that regime, called the limiting SINR. Numerical simulations show that it can approximate the finite-size systems accurately. Furthermore, the simulations also indicate that the DOP scheme can give a better SINR and a higher user capacity compared to those of the FPR scheme.]]>
