Currently, the identification of milk quality requires laboratory tests that are time-consuming because by analyzing the microorganisms commonly found in milk. In addition, milk quality can be directly detected by using the human nose and tongue. However, this is harmful because it can affect the human health. Moreover, the human senses have a different sensitivity that is not accurate in detecting the quality of milk. In this study has developed a sensor system to assess the quality of milk. The role of the human nose is replaced by gas sensor array for the identification of the smell or odor of milk. While the tongue is taken over by a potentiometric sensor array for identification of taste or compounds in the milk. The experimental result shows that this sensor array can produce different patterns to the fresh, sour, and spoiled milk samples. The Neural Network can be used to assess the quality of milk with a success rate of 83%. This technique is expected to be used as a tool to assess the quality of milk quickly, easily, and accurately.

Automation of question generation from a text has been one of the focus of research in recent years. In the education field, question generation can be used to assist in the generation of questions to be used as evaluations of learning outcomes. The process of generating questions with different difficulty levels manually is not easy. Firstly, someone must understand the whole matter and then she or he is able to make questions according to the material. Generation of questions in large quantities and various learning materials will certainly require lot of effort and time. Therefore, it is necessary to automate the process of generating the question. This research introduces question generation automation methods based on Bloom's Taxonomy using text analysis. The method proposed in this study yielded an accuracy of 81.35%. The accuracy proves that the proposed method can be used to generate questions automatically

since early times has recorded history, the people have been utilized wind energy. Wind energy is one of the renewable energy sources and the wind turbine is used to generate electrical energy by the rotational rotor (mechanical energy). The favored form of turbine used for research is the horizontal axis wind turbine (HAWT) with winglets and optimization blade. Blade element momentum (BEM) was used for the design of the blades with 15 segments and the computational fluid dynamics was carried out using fluent for fluid flow through a process using a transient mode and RANS method to solve the problem during an experimental data at the wind tunnel. For the experimental process, the wind tunnel is used for test section on HAWT with velocity variations. The result show, that adding a winglet to existing a blade can change the downwash distribution leading to increased produced power and decrease an induced drag on a long blade, with lower tip speed ratio (TSR), winglet currently give a good starting torque for increase the power of wind turbine.

This paper presents a simple technique to enhance the bandwidth and reduce the mutual coupling in dualband MIMO planar monopole antenna. We use a combination of simple folded slot and partial ground plane. The proposed MIMO antenna structure consists of two planar monopole elements which are arranged side by side on a compact FR4 substrate with dimensions 30×50×1.6 mm3, The existing of the folded slot in patch radiator causes a changing of operation frequency to be two frequencies bands/dualband, i.e., 2.8 GHz/lower frequency and 3.5 GHz/upper frequency. These two frequency bands are addressed to implement 5G mobile communication in Indonesia. According to the simulated results, our technique yields a refinement of mutual coupling approximately 4 dB at upper frequency. In addition, partial ground plane improves a wider impedance bandwidth (S11, S22 < – 10 dB). The improvement of impedance bandwidth values are 9.22 % (antenna 1) & 45.1 % (antenna 2) at lower frequency and 1.19 % (antenna 1) & 42.9 % (antenna 2) at upper frequency, respectively. The obtained envelope correlation coefficient (ECC) values show that partial ground plane also gives a better ECC than full ground plane and its numerical values are less than the MIMO threshold value of 0.3.

There are many systems that offered to prepare and embedded in smart grid technology in the future, such as Power Flow Management (PFM) to control power flow with Distributed Generation (DGs) connection that considered. The network which connected DG is named an Active Distribution Network (AND). DGs connection in the distribution network is purposed to supply load demand, it contributes many impacts in a network as well. These issues might be really possible occurred. One of them is a thermal overload that must be tackled immediately, it leads overheat in the network while DGs output is allowed continuously. Furthermore, DG is not only from the thermal generator (non-renewable) but renewable energy as well. Another term that will be controlled in this research besides DG i.e. Demand Response (DR). DR which called Active Demand (AD) represents an important participant to manage power flow. It transforms the pattern of power on the energy market which affects the interaction among of Distribution Network Operator (DNO), suppliers, and consumers. The algorithm which used to support this system is OPF and CSP. An outcome of this research represents the method which solves this issue and espouses DNO and investors.
未来有许多系统提供准备和嵌入智能电网技术，例如考虑通过分布式发电(dg)连接来控制潮流的潮流管理(PFM)。连接DG的网络称为有源配电网(Active Distribution network, AND)。配电网中dg连接的目的是满足负荷需求，它对电网的影响也很大。这些问题可能真的有可能发生。其中之一是必须立即解决的热过载，它导致网络过热，而dg连续输出是允许的。此外，DG不仅来自热力发电(不可再生)，也是可再生能源。除了DG，本研究还将控制另一个术语，即需求响应(DR)。主动需求(Active Demand, AD)是潮流管理的重要参与者。它改变了能源市场上的电力格局，影响着配电网运营商、供应商和消费者之间的互动。支持该系统的算法是OPF和CSP。本研究的结果代表了解决这一问题的方法，并支持DNO和投资者。

An oscillator is an essential component as the energy source in microwave telecommunication system. This paper design and realize a design of 9.4 GHz dielectric resonator oscillator (DRO) with one stage amplifier. The propose of the added amplifier is to increase high-level output power for system requirements. In this design, the DRO is constructed by using a resonance effect of a dielectric resonator component with the microstrip line coupled. A circuit of RLC shunt is used as dielectric resonator modeling while the quarter wave transformers are used for the matching impedance of the amplifier. The DRO which is deployed on Roger- Duroid 4350 applies the bipolar junction transistor (BJT) of BFP640 type for oscillator circuit and BJT of BFP 840ESD type for the amplifier circuit because those have a low noise figure. The Advanced Design System (ADS) is applied to design and simulate the DRO circuit. The simulation results show the output power at 9.4 GHz is 21.6 dBm while the phase noise exhibits −118.8 dBc/Hz at 100 KHz frequency offset. In the practical measurement, the output power at 9.4 GHz is −2.82 dBm with 20 dB attenuation and the phase noise is −133.48 dBc/Hz at 100 KHz frequency offset.

some hearing-impaired people face a communication problem. Even though they can communicate with others by using sign language, but a lot of people cannot understand the sign language. As a consequence, they can only communicate with limited people. Therefore, we need a Sign Language Recognition System (SLRs) which catch the sign language and translate them into text. Some research about SLRs have been done in some countries. But only a few people conducted research on Indonesian sign language. Further, the research were limited to static features for recognizing static sign language. Other researcher conducted a research on dynamic features, but the dynamic features were good only for dynamic sign language. Thus, in this study we proposed the integration between the static features and dynamic features to recognise both static sign language and dynamic sign language. In this study we conducted two integration scenario. Based on our experiment, recognising whether a gesture was static or dynamic before doing classification produced a good result. The accuracy of this proposed study reach 89% to recognise 20 words.

Constant increasing in the Indonesian population causes an increase in the electricity consumption, as well as the complexity in distribution system networks. Such complex networks require a valid and fair online monitoring and analysis system to allow network maintenance. One of the important components in online monitoring is measurement sensors. It demands quite a lot of sensors for all buses to yield a valid and fair monitoring. However, high investment and maintenance cost must be taken into consideration to build a monitoring system. To resolve this matter, state estimation-a calculation process to estimate unknown variables on a bus-can be used. Using state estimation, expenses can be minimized, because the monitoring system requires less sensors to obtain the same load flow results as if sensors are installed at all buses. Therefore, this research applied state estimation method on a Radial Passive Distribution System using Hamiltonian Cycle Theory. The number of sensors required should be first determined based on the selected buses in the network to conduct estimation based on the Hamiltonian Theory-which estimates the loads at the buses without sensors installed. Then, currents, voltages, losses, and voltage drops can be calculated easily in such distribution system. To understand a visualization of the estimation results, Geographic Information System is used. The simulation results show that this method works satisfactorily to estimate the loads at the buses without sensors in a radial distribution system, and the number of sensors reduces up to 39,29% from the total installed PMU's if they are installed at all buses.

The number of sensors required should be first determined based on the selected buses in the network to conduct estimation based on the Hamiltonian Theory-which estimates the loads at the buses without sensors installed. Then, currents, voltages, losses, and voltage drops can be calculated easily in such distribution system. To understand a visualization of the estimation results, Geographic Information System is used. The simulation results show that this method works satisfactorily to estimate the loads at the buses without sensors in a radial distribution system, and the number of sensors reduces up to 39,29% from the total installed PMU's if they are installed at all buses.","PeriodicalId":388463,"journal":{"name":"2018 International Seminar on Intelligent Technology and Its Applications (ISITIA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123554030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
