Kediri City is a stopover/transit city and has many potentials in the fields of tourism, education, and industry. Thus, the City of Kediri became one of the cities that are very likely to develop and be crowded. Therefore, it is required to model city tours in several primary fields of Kediri City. In the literature, determining the optimum route can be approached as a traveling salesman problem. However, traveling salesman problem model cannot be used to determine the city tour path as the distance among the point may vary. In this study, we used the concept of asymmetric traveling salesman problem to solve the city tour path. Furthermore, we used the ant colony system algorithm to solve this problem. The cases resolved in this study are the location of the tourism center, industrial center, and education center in Kediri City. The results show the ant colony system is capable of providing optimum tour route solutions, namely the city tourist route 34.65 km, the industrial route 21.19 km, and the school route 28 km.

Wheeling is a solution to the complexity of transmission network constructing problem. With the wheeling concept, a power plant owner can deliver electricity to its load without having to construct a transmission network. The owner of the power plant can utilize the transmission network belonging to other entities. The wheeling concept is an interesting thing in terms of increasing current renewable energy penetration. This is due to the construction of the transmission network, which is one of the obstacles in increasing renewable energy penetration. Fairness of wheeling costs is still one important topic. The discussion regarding wheeling costs emphasizes that the costs charged to each party involved can meet the fairness principle, which is in accordance with their respective contributions to the implementation of wheeling. Broadly speaking, research related to wheeling can be grouped into research for developing wheeling cost calculation methods and research for developing wheeling cost allocation methods. The development of the wheeling cost calculation method also includes the development of cost components that can be included in the cost calculation. This study summarizes the discussion of wheeling costs on three aspects, namely calculation methods, cost components, and cost allocation mechanisms.

The uncertainty of health news content, which is spread on social media, raises the need for validation of the truth. One validation approach is to consider the opinion or attitudes of most people, which is called a stance on a topic, whether they support, oppose, or being neutral. This paper proposes a stance analysis model to classify the relationship between sentences so that it can recognize the correlation of the opinion of the writer in the headline of the problem claim. The proposed model uses several Long Short-Term Memory (LSTM), which represent the interrelationship of news for analysis of the relationship between a claim with other news. The formation of word representation vectors is carried out in conjunction with LSTM-based stance classification training. Sentence embedding is done to get the vector representation of sentences with LSTM. Each word in a sentence occupies one time-step in LSTM and the output of the last word is taken as a sentence representation. Based on the results of trials with the Indonesian health-related dataset that was built for this study, the proposed stance classification model was able to achieve an average F1-score value of 71%, with the supporting value 69%, opposing as much as 70%, and neutral 74%.

Point of Sale (POS) application in MSMEs is used as a tool for making sales. La Fresa Farm uses POS Intuit QuickBooks Enterprise 2015 application. As long as this application is implemented, users need a fairly long interaction time. Seeing these problems, tools are needed to evaluate the use of the application. In this study, the evaluation model used is the Technology Acceptance Model (TAM). TAM describes the ease of use and usefulness variables as the first measuring variables that affect other variables to the actual to use variable. The ease of use variable is the interaction time, which is measured using Keystroke Level Model (KLM). The usefulness variable is measured by cognitive models. In this study, there are additional variables outside the TAM model, namely self-efficacy, timeliness, and complexity. The test was carried out by the POS Intuit QuickBooks Enterprise 2015, Moka, Pawon, and Olsera applications. The KLM test results showed that the fastest time was 89.8 seconds and the results of TAM evaluation on Moka showed that the results of the actual to use variable response had a positive response, so that the interest of users using Moka was quite high.

This paper describes a low-cost solar panel simulator for Maximum Power Point Tracking (MPPT) method testing, especially under partially shading conditions. The simulator consists of a DC power supply and a solar panel. The simulator works to emulate the characteristics of solar panels without depending on artificial illumination or sunlight. The simulator can represent the needed irradiation through the settings on the DC power supply. The experimental setup is developed to emulate the characteristics of solar panels at Standard Test Conditions (STC) irradiation conditions as well as varying irradiation conditions. Testing is done to emulate irradiation varies from 200-1,000 W/m2. To emulate the characteristics of solar panels in partial shading conditions, two DC power supply units and two solar panels are used. Each solar panel is simulated to receive different solar irradiations. The test results show that the simulator can emulate the characteristics of solar panels under partial shading conditions which has several maximum power points. Furthermore, partial shading conditions are simulated under varying irradiation conditions which resulted varying maximum power point values.

Indonesia government has launched a program to encourage youth entrepreneurship as a strategy to improve national economy. This paper proposes a method to find an entrepreneurial potential based on academic behavior features that are extracted from the Higher Education Database PDDikti. The proposed approach applies the Fuzzy Multi-Attribute Decision Making (FMADM) technique. Rules for extracting features of student academic behavior were following Theory of Planned Behavior (TPB) and resulting in 14 features. The FMADM model combines Fuzzy Simple Additive Weighting and Fuzzy Technique for Order Preference by Similarity to Ideal Solution, which is called FSAW-TOPSIS. Friedman Test demonstrated that FSAW-TOPSIS gives more optimal solution with the highest Mean Rank of the potential entrepreneurial value of 2.96. Besides, through Hamming Distance Test, FSAW-TOPSIS results the best order with a 98% percentage and ranking of the smallest Squared Error of 0.3%, which makes the proposed model offered a better solution. It can be concluded that using TPB variables in PDDikti environment with FSAW-TOPSIS technique provides an optimal recommendation on student entrepreneurship potential, which can be used as a part of a decision-making system for higher education management.

Along with the rapid development of technology, many techniques have been employed to improve filter performance by using microstrip, one of them is using a Defected Ground Structure (DGS) technique. The DGS is a technique implemented by combining various forms of slot on the ground-plane of filter. This paper presents an ultra wideband (UWB) filter designed using DGS technique by combining two kind of slots on the ground plane, i.e., rectangular slot and rectangular ring slot. The design of composed filter is initialized using filter without DGS, then by adding two kinds of DGS on the ground plane. The DGS is used to improve S-parameter values and increase bandwidth. The method of filter design is using several parametric studies, such as changing the length of patch, width of patch, number of rectangular slot, length of rectangular slot, width of rectangular slot, and gap in rectangular ring slot. This filter is fabricated on a FR4 epoxy dielectric substrate with the thickness of 0.8 mm and the size of 27.4 mm x 22 mm. The measurement result shows that the filter could produce the working bandwidth of 4.01 GHz in the frequency range from 1.52 GHz to 5.53 GHz.

The evolution of communication network comes from the need for users to stay connected anytime and anywhere. Modernization of the network continues to be done to increase bandwidth capacity in order to obtain an increase in multimedia services, especially in urban areas. Of various transmission media, optical fiber is the best choice to support reliable communication networks. One of the optical fiber communication technologies is Fiber to the Home (FTTH). This study proposes FTTH network design with Gigabit Capable Passive Optical Network (GPON) technology aimed at housing in urban areas. The design uses aerial and duct-aerial cabling sy stems. The design analysis is carried out based on the parameters of the link power budget, rise time, Bit Error Rate (BER), components and costs required. The value of the power budget link for the uplink and downlink are -22.792 dBm and -23.120 dBm. The rise time value for uplink and downlink are 0.256 ns and 0.258 ns, while the BER value is 14.628 x 10-12. The calculation results show that the design meets the required parameters, hence, the proposed network can be implemented. For the cost components required by the aerial system, it is 11.56% less than of the duct-aerial sistem.

In the last decade, planar electromagnetic (EM) wave absorbers began to be widely studied. This type of EM wave absorber is thin, flexible, and easy to fabricate, which allows absorber to be used in new future applications. Split Ring Resonators (SRR) are one of many forms of absorber that is known to have an excellent absorbance performance. In this paper, square patch absorber, Axial Symmetric SRR (AS-SRR), and Axially Asymmetric SRR (AAS-SRR) are designed and observed in C-Band. From the simulation results, we obtained a square cell size of 30 mm, AS-SRR of 20 mm, and AAS-SRR of 18 mm. The three forms can reach absorption rates above 92%, with a bandwidth of 0.055 GHz, 0.076 GHz, and 0.081 GHz, respectively. Furthermore, the AAS-SRR design parameters were characterized, and the main parameters that influence the bandwidth and resonant frequency are the resonator length and resonator thickness. The maximum bandwidth of the characterization is 0.087 GHz.

Loss of synchronization causes a generator not in steady state condition, causing system instability. In this paper, Nyquist method is used to determine the transient stability of a synchronous generator using the Nyquist curve. The system is unstable if the G(jω) curve is further away from the point -1 + j0, while the gain margin value is below 6 dB and the phase margin has a value below 30°. The response of the system shows that the rotor angle oscillation on the generator is not synchronous, while the power angle experiences irregular transients so that the power angle increases until it cannot return to its steady state position. By using the Static Series Synchronous Compensator (SSSC) filter, the rotor angle oscillation response after 0.1 seconds begins to stabilize at an angle of 50°. The effect of the SSSC filter also affects the bus voltage oscillations from 0.15 seconds to 0.05 seconds and the real power oscillations from 0.13 seconds to 0.06 seconds.
