5G communication have a lot of advantages inour daily activity. The development of 5G, allows some mobility communication, like a car that especially needs some communication for the user and supporting V2X (Vehicle to Everything) application. Wider bandwidth is the one that to be required. ETSI and 5GCar said that for supporting 5G communication, many countries using bandwidth antenna more than 500 MHz. Inthis study use parasitic patch method for wider the bandwidth, the antenna design process begins by determining the antenna parameters. Next, design a conventional single microstrip antenna and then added more resonances with the process of enhance the bandwidth using the parasitic patch technique, with adding resonator in coplanar method. The parasitic patch is electrically not connected from the central patch, but patch using edge coupled utilization. This present design of the parasitic antenna use frequency of 3.5 GHz with width of antenna 68.71 and length 48.58 mm. Substrate antenna using an FR4 and use 50 Ω coaxial probe for fed technique. The proposed design antenna has 5patch parasitic with gap coupling for staggering resonance and yet wider bandwidth. The results of the proposed antenna can achieved bandwidth untill 658.1 MHz, with range of frequency from 3,3158 GHz to 4.0066 GHz with antenna dimension 68.71×48.58 mm. Meanwhile, the gain resulted is 4.89 dBi.

We investigate the aggregate interference caused by large scale NGSO constellations to GSO systems. We propose starlink and Telkom-3S satellite as a case study. We utilize the TLE, a (near-) real-time orbital elements, and simulate the downlink interference scenario. Based on the simulation results, we found that in the range of latitude 0 to 40°N, the higher the latitude of the GSO receiver, the less the number of interference events. We also observe that the EPFD will exceed the interference limit recommended by ITU-R article 22.

Named Data Networking (NDN) is a network with a future internet architecture that changes the point of view in networking from host-centric to data-centric. Named data networking provides a network system where the routing system is no longer dependent on traditional IP. Network packets are routed through nodes by name. When many manufacturers produce packages with different names for several consumers, routing with load balancing is necessary. The case study carried out is to conduct a simulation by connecting all UIN campuses into a topology with the name UIN Topology in Indonesia, using several scenarios to describe the effectiveness of the load balancer on the UIN topology in Indonesia. This study focuses on load balancer applications to reduce delays in Named Data Networking (NDN), the topology of UIN in Indonesia.

The frequent use of the Volvo engine for mechanical hauling necessitates a real-time and intelligent approach to when and how to perform periodic maintenance. The single or double trailer (vessel) that the Volvo FH16 prime mover truck is equipped to pull may weigh between 280 metric tons. Unfortunately, the Service-Meter (SM), which counts engine operating hours without accounting for engine speed, load, or oil temperature, serves as the primary basis for the maintenance schedule. As a result of this faulty parameter, the maintenance schedule became inefficient and flawed. A NodeMCU Module is installed on an ECU to include crankshaft rotation to Hour Meter parameter which used to decide when to carried out the periodic maintenance. The wear components inside the engine that is in contact with rotating or moving parts such as crankshaft, camshaft, piston cylinders specifically the rings, cylinder liner, and connecting rod are all depend on the number of crankshaft rotation. By including the crankshaft RPM when the engine is operating, using SMconv, The most frequent maintenance service (PS250) is carried out approximately every 11 days (previously every 15 days). By making PS250 more frequent which means replacement of engine oil, engine oil filter, and secondary fuel filter (racor filter) will be done more frequently. The result and effect of the maintenance is therefore in accordance with metal wear pace inside the engine. Therefore, by modifying the SM parameter the more frequent maintenance service is expected to make make better MTBF and MTTR thus resulting in longer engine lifetime.

The concept of the internet in the future will prioritize content, by reducing delays in data transmission. Named Data Networking (NDN) is a content-based future internet concept that changes the paradigm of using IP. Inside the NDN router, there are three data structures, namely Content Store (CS), Pending Interest Table (PIT), and Forwarding Information Base (FIB). Pending Interest Table (PIT) contains a list of unfulfilled interests. This condition occurs when the node has not received a response after the interest forwarding process. Measurable and fast PIT performance is a challenge in Named Data Networks. In this study, we will try to do a simulation to measure and analyze the performance of PIT in NDN in the Palapa Ring topology. The research was conducted using the NDNSim simulator, to see the performance in the PIT. The simulation and analysis of the results show that the granularity of a prefix has an effect on In Satisfied Interest in an NDN network. At the number of interests of 100, the result obtained from the simulation is that there is a decrease in the percentage of interest data served, amounting to more than 20%. At the amount of interest in 1000 about more than 30%. The length of the prefix and the number of interest sent by the consumer affect the performance of the PIT, seen from the number of In Satisfied Interests.
未来的互联网概念将通过减少数据传输的延迟来优先考虑内容。命名数据网络(NDN)是一种基于内容的未来互联网概念，它改变了IP的使用范式。在NDN路由器内部，有三种数据结构，即CS (Content Store)、PIT (Pending Interest Table)和FIB (Forwarding Information Base)。未决利息表(PIT)包含未完成的利息列表。当节点在兴趣转发过程之后没有收到响应时，就会出现这种情况。在命名数据网络中，可测量和快速的PIT性能是一个挑战。在本研究中，我们将尝试做一个模拟来测量和分析在Palapa环拓扑下NDN中PIT的性能。研究使用NDNSim模拟器进行，以查看在PIT中的性能。仿真和分析结果表明，前缀粒度对NDN网络中的“满意兴趣”有一定的影响。在兴趣数为100时，仿真得到的结果是服务的兴趣数据百分比减少了20%以上。在1000的金额利息约30%以上。前缀的长度和消费者发送的兴趣的数量影响PIT的性能，从满足兴趣的数量可以看出。

Indonesia is the largest agrarian country in the world with abundant natural resources, especially in the plantation sector. The greenhouse concept can be developed by adding a smart greenhouse system with Internet of Things (IoT) technology which can accelerate an accurate and expected plant cultivation system. This study introduces a smart greenhouse system for chili cultivation based on the IoT using website technology of NodeJS as an application interface and MongoDB as a database. The system that has been developed consists of several sensors designed to collect information related to the environmental conditions of the greenhouse. These sensors are Total Dissolved Solid/TDS (water turbidity) sensor, Dissolved Oxygen Sensor (Oxygen content), DHT11 (air temperature and humidity), pH sensor (soil pH), soil moisture sensor (soil moisture), and ultrasonic sensor (to measure the distance from the water surface). The system is developed using the Message Queuing Telemetry Transport (MQTT) protocol. Data from the sensor is delivered to the Raspberry Pi 3B and the server passes through the internet network to be stored in the database. Testing of the DHT11 sensor produces an average air temperature of 26°C and air humidity of 62% which affects the growth of chili plants while the results of testing the water pH data are 6.36 mg/l. The value of the oxygen content (Dissolved Oxygen (DO)) is 0 - 2.141 ppm while the value of the Water Level data in the reservoir is 14.7 - 19.2 cm. Testing of water turbidity uses TDS (Total Dissolved Solids) sensor. This test is performed to ensure good water quality for chili plants which is in the range of 3 - 3.5 ppm. Messages sent by MQTT have 100% delivery success rate, smaller payload size compared to HTTP, and lower device power consumption.

Seagrass ecosystems are known to be able to absorb and store carbon both in vegetation and in the substrates where seagrasses grow. The value of these carbon reserves varies depending on the characteristics, conditions, and extent of seagrass ecosystems, but seagrass ecosystem areas have declined globally due to the threat of development that is not environmentally friendly. By those reason, this research purpose for determining seagrass ecosystem by measuring the blue carbon using Lyzenga Algorithm in QGIS Application. The value of these carbon reserves varies depending on the characteristics, conditions, and extent of seagrass ecosystems, but seagrass ecosystem areas have declined globally due to the threat of development that is not environmentally friendly. The method used is purposive sampling at a predetermined station and retrieving image data from Sentinel-2 to measure the area which is further analyzed descriptively to assume the value of carbon uptake in Bara Beach, South Sulawesi, whose carbon sequestration value on the coast of Bara Beach has an average carbon stock in the seagrass type Enhalus acoroides of 391.95 gC/m2, Halodule uninervis at 43.33 gC/m2 and Thalassia hempricii at 303.23 gC/m2. The estimated carbon uptake value in Bara Beach with a coastal area according to Qgis analysis of 41,453 ha is 15,541 MgC from 12.6 ha of classified seagrass ecosystem area has an unhealthy or moderate quality level with an overall ecosystem density percentage of 30.44%.

The development of a fire fighting robot requires a fire detector with high accuracy, which is influenced by the input signal received from the sensor. It was embedded in the robot. The fire fighting robot requires a control method used by the robot in the fire detection process. In this study, the flame detector KY -026 ultrasonic was installed on the front of the robot and used Arduino MEGA 2560 as the microcontroller. In order to make the robot movement more stable when detecting fire, a Fuzzy Logic controls the fan and DC motor PWM. Testing Fuzzy Logic on the robot is carried out with the condition that the robot detects fire on a candle with a distance of 20 cm for the ultrasonic sensor and the ADC value of 300 for the flame detector.

Brushless Direct Current (BLDC) motors have the characteristics of better speed and torque control, high efficiency, and affordable maintenance costs compared to other types of electric motors. BLDC motors require a control system that can produce stable and responsive torque to maximize these advantages. This study discusses torque control with Proportional Integral (PI) control and Field Oriented Control (FOC) method using DSP LaunchPad XL TMS320F28069M. This research simulates the PI control to see the results of the control before it is implemented on the BLDC motor. The simulation results obtained a Kp value of 0.80541 and a Ki of 0.42578. The final result of this study shows a good response with a small overshoot value and steady state error, resulting an output with low ripple, a stable system, and a fast response. The designed control system is capable of tracking torque at Iq 0.3A, 0.6A, and 0.9A setpoints. Sequentially, the settling time values were 0.02ms, 0.06ms, and 0.16ms; the overshoot values were 0.042%, 0.02%, and 0.01%; and the steady state error values for each setpoint were 0.06%, 0.03%, and 0,03%.
