This paper discusses the design of a dual-band microstrip antenna for 5G applications with a slot loading technique in the form of a U-Slot. This antenna is designed to work on the 5G service frequency in Indonesia at a frequency of 1.848 GHz (1.8375 -1.8575 GHz) and a frequency of 2.315 GHz (2.300 - 2.330 GHz). The feeding technique used is a feedline feeding technique, while the substrate material used is FR-4 Epoxy with a purity of 4.3 and a thickness of 1.6 mm. In this paper, two antenna designs are compared, namely the conventional antenna design and the antenna design with a U-Slot operating at the same frequency. Parameters compared are antenna dimensions, return loss, VSWR, gain and bandwidth. The addition of a U-Slot on a dual-band microstrip antenna managed to reduce the antenna dimensions by 32.3 % and still be able to work on 5G frequencies in Indonesia with performance that is on target.

Making tofu and the level of production speed in the food industry cannot be separated from fully automatic machines. The press machine knows the pneumatic system with PLC control affects production productivity. Conventional tofu press machines are said not to meet the needs of today's industry because they still use human power, the weight of stones or jerry cans filled with water. The compressive force required when pressing tofu is 15 kg. PLC is an electronic computer that is easy to use (user friendly) and has control functions for various types and various levels of difficulty. At the testing and measurement stage, a power supply with a capacity of 24Volt Dc is used because each sensor requires a voltage of 24Volt Dc, The output of the measurement results on the sensor has different voltage values; from that value, it does not interfere with the sensor's work because the voltage is still following the sensor datasheet. From the results of design testing with a pneumatic trainer where the pneumatic cylinder cycle follows what is expected (A+A-B+C+C-B-). And from the calculation results of the Tofu Press Machine Frame using theSolidworks application is declared safe.
食品工业中豆腐的制作和生产速度的高低离不开全自动机器。压力机知道用PLC控制的气动系统影响生产效率。据说，传统的豆腐压榨机已经不能满足当今行业的需求，因为它们仍然需要人力、石头或装满水的易拉罐的重量。压豆腐时所需的压缩力为15kg。PLC是一种易于使用(用户友好)的电子计算机，具有各种类型和各种难度等级的控制功能。在测试和测量阶段，由于每个传感器需要24v直流电压，因此使用容量为24v直流的电源，在传感器上输出的测量结果具有不同的电压值;从该值开始，它不会干扰传感器的工作，因为电压仍然遵循传感器数据表。根据气动训练器的设计测试结果，气缸循环遵循预期(a + a - b +C+C- b -)。并且从计算结果来看，豆腐压榨机机架采用solidworks应用程序是安全的。

News gives new insight and information from all over the world. News has many categories, such as politic, economy, science, and other common news categories. Every news will have their own category based on its content. The classification of news is usually done manually by inputting the category during the news posting. Some of the categories may be inputted incorrectly. The news classifier can be the solution for problem, but the news classifications out there are usually based on the news content. The classifier will receive the word vector inputs that are taken from the news content and try to classify it into one of certain categories. Unfortunately, news contents can be longer and harder to be processed rather than processing the news headline. The news headline is shorter and packs a decent information for the classifier to find out what category it is. Besides the news headline usage, the classifier also needs to be chosen correctly. In this paper, the SVC model will be tested using the news headline data to classify the news and compare with several other models, such as Linear Regression, Multinomial Naive Bayes, Decision Tree, and Random Forest. The common variables to be compared are the accuracy, recall, and precision to evaluate the SVC model.

Generalized frequency division multiplexing (GFDM), which not only meet the needs of the 5G network but also has great compatibility with OFDM, is one strong waveform candidate. However, it is essential to have a good performance of low complexity synchronization and channel equalization (CE) of it to fully reap the advantageous features. A simple method to solve CE is the least square (LS), but it requires pilot symbols, thus degrading the frame efficiency. Commonly, the CE techniques assume perfect synchronization, which is not practical. A method utilizing the adaptive filter is able to jointly solve the synchronization and channel issue, but at a cost of high complexity. To address the issue, a technique that maximizes the utilization of preamble is proposed. A preamble constructed by deterministic sequence is treated as pilots, and can be used for joint synchronization and CE. Here, no pilot should be inserted among the payload. The performance is observed similar to conventional LS technique, but at frame efficiency of3.76% higher.

A detailed design procedure for an S band bias tee used in a high power application is provided in this paper. A substrate with 3.66 relative permittivity and 0.762 mm in thickness is used. The proposed bias tee design utilizes an RF short-circuit in the form of a radial stub and a λ/4 transformer to implement the RF choke. A capacitor with appropriate specifications are used as the bias tee's DC block to complete the bias tee. To optimize the bias tee's form factor, a meandering approach with mitered lines are used. The resulting bias tee achieved RF - DC isolation, insertion loss, and return loss of better than -20 dB, -0.1 dB, and -24 dB respectively from 2.9 GHz to 3.5 GHz. Evidence of the realized bias tee's functionality is also provided in its utilization on an balanced S band power amplifier.

Sparse representation based Classification (SRC) has gained the attention of pattern recognition and computer vision researchers, especially researchers working on face recognition. On SRC's algorithm, it is necessary to find a solution to an optimization problem to recover $mathbf{x}$ from the equation $mathbf{y}$ = Ax. Only a few studies reported the reconstruction of the signals on SRC's algorithm. Therefore, this paper studies the comparison of OMP, LASSO, and CVX to help the readers understand the reconstruction algorithm's effect on SRC. The simulation result is that LASSO and CVX algorithms have the same recognition rate, but LASSO can compute twice faster as CVX. On the other hand, the OMP algorithm can give the highest recognition rate on a specific dimension of the image with a faster computation time than LASSO.

In this article, a multiband compact patch antenna and a multiband rectifier circuit is proposed for a rectenna operating at 2.4 GHz and 5.8 GHz for RF energy harvesting and wireless power transmission. A modified inverted F shape antenna is used as the main receiving component of the rectenna. The antenna has a compact size of 35×40 mm2. The proposed antenna has good impedance bandwidth (for S11< -10 dB) values of 230 MHz and 620 MHz at the resonant frequencies 2.4 GHz and 5.8 GHz, respectively. The gain values are 3.6 dB and 3.3 dB at 2.4 GHz and 5.8 GHz, respectively. Furthermore, an efficient dual band rectifier circuit is presented. The rectifier circuit is a single branch and consists of a matching network, voltage doubler circuit and a load. The proposed rectifier circuit is designed on RT-Duroid 5880 substrate and the HSMS2850 diode is used for rectification. The rectifier achieves very good efficiency at both frequencies i.e., 71 % and 51.9 % at 2.4 GHz and 5.8 GHz respectively.

Nowadays, mobile device technology has driven the need for more flexible charging using wireless technology. This technology is called wireless charging, a wireless technology used to transfer power to mobile devices. A wireless power transfer system consists of three parts: oscillator, power amplifier, and radiator. The oscillator is designed using a 74HC04 CMOS IC as the main part of the oscillator and a 13.56MHz crystal and is equipped with a common-collector amplifier using a Bipolar Junction Transistor (BJT) type BC547. This study discussed the optimization of the oscillator with the tuning method on the values of capacitors C1, C2, C3, and C4 and resistors R2, R3, and R4 to increase the signal output level. This research produces an output signal on the oscillator of -0.246dBm and a peak amplitude of 5.1V at a frequency of 13.573MHz. Compared to the previous study, the signal output has increased by 4.544 dBm, where the previous study produced a signal output of -4.79dBm with a peak amplitude of 0.95V at a frequency of 13.56MHz.

Public awareness about health is still deficient due to limited public knowledge in the health sector. Another problem is the limited availability of experts, especially in sexual health. Currently, health clinics that provide consultation for patients with venereal disease are still very limited. Awareness of venereal disease in Indonesia is still lacking, and there is still a reluctance to seek treatment or consult with venereal disease. Sexually transmitted diseases can be transmitted through sexual and non-sexual intercourse. Based on these problems, this study aims to build an expert system for diagnosing venereal diseases using the Certainty Factor method with Confusion Matrix for Multi-Class - Classification. The results of the study based on the accuracy test with the Confusion Matrix for Multi-Class Classification approach of 95% with an RMSE level of 0.091897

This study proposes a method for the internet of things in the cyber-physical system (CPS) for smart agriculture systems for sorting potatoes for post-harvest processing. Sorting is currently the most essential part of the production stage, namely at the time of sorting at harvest time. Using the smart system layer architecture, the automatic sorting machine plays as an instrumentation layer in CPS. The parameters used in the sorting setting are sweet potatoes' color, shape, size, mass, and water content. This automatic sorting machine assesses the quality of sweet potatoes based on the water content and weight. The loT instrumentation layer uses a weight sensor HX711 and measures the water content with a parallel plate. As discussed in this paper the sensor data determine the decision to sort sweet potato quality values based on Indonesian National Standard (SNI). It also shows how the measurement data can be used in further research for smart agriculture system.

Sorting is currently the most essential part of the production stage, namely at the time of sorting at harvest time. Using the smart system layer architecture, the automatic sorting machine plays as an instrumentation layer in CPS. The parameters used in the sorting setting are sweet potatoes' color, shape, size, mass, and water content. This automatic sorting machine assesses the quality of sweet potatoes based on the water content and weight. The loT instrumentation layer uses a weight sensor HX711 and measures the water content with a parallel plate. As discussed in this paper the sensor data determine the decision to sort sweet potato quality values based on Indonesian National Standard (SNI). It also shows how the measurement data can be used in further research for smart agriculture system.","PeriodicalId":164665,"journal":{"name":"2022 16th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121511668","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}
