Telecommunication services globally use two communication systems: terrestrial and satellite, but they still have weaknesses that must be addressed immediately. An alternative is High Altitude Platform Station (HAPS), which was studied extensively in the 1990s and 2000s, and is now returning to public attention. In this study, we firstly determine the optimal HAPS position assuming equal power allocation to each User Equipment (UE) in order to maximize the downlink Sum Rate given a backhaul link constraint and minimum data rate of each UE. HAPS operates at the 28 GHz millimeter-wave band with an altitude of 20 km. The antenna configuration is Uniform Planar Array (UPA) with varying number of elements. The number of UE is fixed but randomly distributed in an area of 100x100 km2. The area is divided into 100 equal-sized grids, from which the HAPS location will be varied for optimization purpose. The simulation results indicate that the optimal location is grid number 29 when the antenna element is 16x16. Increasing the antenna element to 128x128 results in higher data rate for each UE. After determining the optimal HAPS location, power allocation for each UE is carried out to fulfill the backhaul link constraint. From several power combinations for each UE, the combination that has the minimum total power is taken. Thus, as the array elements increase, the total minimum power will decrease.

In multi-layer LTE configuration, LTE 900 MHz band placed as the outer layer due to its large coverage and small bandwidth available. This layering configuration makes the LTE 900 MHz coverage only focused for the cell-edge users (CEU) while the cell-center users (CCU) are served by other inner layer bands. Consequently, the LTE 900 MHz users suffer from inter-cell interferences (ICI) more than user in other bands. This paper presents a performance comparison of three different frequency reuse schemes for mitigating ICI, namely Strict Fractional Frequency Reuse (strict FFR), Soft Fractional Frequency Reuse (soft FFR), and Hard Frequency Reuse with reuse factor of 3. The performances evaluated using average user throughput and average Signal to Interference and Noise Ratio (SINR) for users in the cell edge. The simulation results show that the Hard Frequency Reuse Scheme provides the highest performance, particularly for outer layer in multi-layer LTE configuration.

An Unmanned Aerial Vehicle (UAV) is operated remotely using a Ground Control Station (GCS). Conventional GCS usually has limited range for it to be able to control and monitor the UAV due to limitations of the telemetry module. GCS capable of limitless range of connectivity with UAV will give a lot of advantage and unlock more potential of UAVs. This paper proposes the idea of implementing a web server as an intermediate communication component between UAV and GCS to realize the idea of unlimited range UAV control and monitoring. The web server is developed in Node.js environment with the help of Hapi Js framework. In addition, this paper also proposes the implementation of IoT device as an antenna tracker to improve the range of UA V telemetry modules and at the same time provide the connection to a web server on the internet. For this implementation, Raspberry Pi is chosen as an IoT device due to its capabilities and powerful specification. This system configuration will provide stable, wide range, and remote connectivity between UAV and GCS.

This paper presents the implementation of the forward kinematics Denavit-Hartenberg method on a 3 DOF arm robot which is implemented on a coffee maker. This system imitates human movement which works as a regulator of the movement direction of the robotic arm joints. Degree of Freedom (DOF) is set to support the movement method of the manipulator robot. In the process of making coffee, a robotic arm requires a minimum of 3 to 4 joints (3 to 4-DOF) to do the job of imitating a human arm. The forward kinematics method uses kinematic equations to determine the joints of the robot so that the final coordinates of its movement can be determined. The Denavit-Hartenberg method is implemented on 4 variables that become parameters for analyzing the forward kinematics robot movement. These four parameters are used in matrix transformation to determine the relationship between matrices which represents the position and orientation of one body to another. Overall, the results of repeatability testing in moving coffee cups with a deviation standard value for the x-coordinate is 0.060, for the y-coordinate is 0.020 and for the z-coordinate is 0.000. In accordance with the deviation standard theory that smaller deviation standard value, better the repeatability.

The need for water is increasing daily along with the increasing population in an area. One of the reasons for increasing water demand is boarding houses. The water consumption limit for luxury boarding houses is 123.45 liters/person/day; for medium boarding houses, it is 120.52 liters/person/day, and for simple boarding houses, 115.86 liters/person/day. In this study, a water usage monitoring system was designed using an Internet of Things-based application to monitor water discharge and volume via a smartphone. This system uses a water flow sensor, solenoid valve, and Arduino Uno ATMega microcontroller, which is communicated serially with the ESP8266, a two-channel relay, and a water pump so that water can flow quite fast. The monitoring system designed can calculate the water discharge and the volume of water usage for boarding house residents per day with a water usage limit of 123 liters/person/day. If the boarding house occupants use water exceeding the predetermined limit, the excess water usage fee will be charged to the house occupant. This monitoring system is implemented in 2 rooms in a boarding house. Based on the tests that have been carried out, the average water consumption in Room 1 is 123.72 liters, with an average water flow of 22.41 liters/min. In comparison, the average water consumption in Room 2 is 116.54 liters, with an average water discharge of 21.48 liters/min. Then the accuracy value of the water discharge is 99.88%, the water volume is 98.88% in Room 1, the accuracy value of the water discharge is 99.85%, and the water volume is 95.19% in Room 2. This shows that the monitoring system can work according to the design, where the monitoring system can display the daily water usage of boarding house residents through the Blynk application. Then the monitoring result data is sent to the user via email that the occupant has registered on the Blynk application.
随着一个地区人口的增加，对水的需求每天都在增加。用水需求增加的原因之一是寄宿公寓。豪华公寓用水量限制为123.45升/人/日;中型公寓为120.52升/人/天，简易公寓为115.86升/人/天。在本研究中，利用基于物联网的应用程序设计了一个用水监测系统，通过智能手机监测用水量和水量。该系统使用水流传感器、电磁阀和Arduino Uno ATMega微控制器，该微控制器与ESP8266、双通道继电器和水泵串行通信，从而使水流得相当快。所设计的监控系统可以计算出公寓居民每天的排水量和用水量，用水量上限为123升/人/天。如果住宿者使用的水超过预定的限制，多余的水费将被收取给住宿者。该监控系统在某寄宿公寓的2个房间实施。根据已经进行的测试，1号房间的平均用水量为123.72升，平均水流量为22.41升/分钟。相比之下，2号房间的平均用水量为116.54升，平均排水量为21.48升/分钟。则排水量精度值为99.88%，1号房排水量为98.88%，2号房排水量精度值为99.85%，2号房排水量为95.19%。这说明监控系统可以按照设计工作，其中监控系统可以通过Blynk应用显示公寓居民的日常用水情况。然后，监控结果数据通过电子邮件发送给用户，该用户已在Blynk应用程序上注册。

Well Measurement of water level is very important for Geothermal Well operations. Manual measurement is very ineffective and inefficient because the water level cannot be monitored in real time. So, a wireless interface communication system was designed to monitor water level using ultrasonic sensor and the NRF24LOl+ PA LNA transceiver communication module. The NRF24LOI + P A LNA is a long-distance wireless communication module that utilizes a 2.4-2.5 GHz radio wave frequency equipped with a Low Noise Amplifier and Power Amplifier. The distance data from the sensor transmitted by the NRF24LOI + P A LNA communication module will be displayed on the LCD and the thingspeak website platform. By using this method, the water level can be monitored quickly in real time and efficiently. The test results of communication modules show that the capability of the NRF24LOl+ PA LNA module is quite good and effective in transmitting data at a maximum distance of 200 meters.

The test results of communication modules show that the capability of the NRF24LOl+ PA LNA module is quite good and effective in transmitting data at a maximum distance of 200 meters.","PeriodicalId":164665,"journal":{"name":"2022 16th International Conference on Telecommunication Systems, Services, and Applications (TSSA)","volume":"57 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":"114936925","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}
The study was conducted to model Wi-Fi password resource assets in a platform that can be shared and collaborated publicly securely and support dynamic data changes with online repository shortcuts documented in access support via dedicated search engines and QR CODE. This study uses 3 methods, namely the one-way SHA-256 HASH function which was formulated with the addition of sowing techniques and reversing techniques so as to produce a long String named Keycode, the second method uses modern cryptographic techniques, namely Digital Signature, which collects keycodes in Path the identity of the resource asset, and the last one is a QR CODE used as an access shortcut that collects digital signature access data. This study used testing data from comparator application contributors, namely wifimap.io randomly, the results of which the formulation results were then disassembled using the brute force technique using hashcat. The results of the research of password data from resources were successfully formulated into a combination of Strings with high confidentiality that cannot be disassembled to the original data but are still accessible to the owner and holder of the keycode that is balanced with the limitations of access control.

In this paper the use of a 36Mbps Satellite Ku-Band transponder that will be used for internet services for VSAT terminals. The capacity of the Ku-Band transponder serves several VSATs that will be connected to broadband internet through the Hub station. Transponder Satellite is a resource that is limited in bandwidth and limited in power, of course, planning is needed in its application. Planning for the optimal use of satellite transponders is carried out using Network Simulator NS-2. The satellite transponder used for internet services provides bandwidth for both Hub stations and VSAT terminals. This satellite internet service uses the TCP/IP communication protocol which will access services from the VSAT terminal to the hub station. Planning the use of transponders with NS-2 will obtain QoS parameters including throughput, packet loss, end to end delay and packet received. This can be obtained from QoS information from VSAT that uses Ku-Band transponders for internet services.
