The Autonomous Submarine Surface Vehicle is a type of unmanned underwater vehicle. When the ship performs maneuvers, there are large Pitch and Roll motions. This research aims to control the stability of the Autonomous Submarine Surface Vehicle with Fuzzy. The first process is taking Pitch and Roll data followed by the Fuzzification process to change input data with firm values into Fuzzy values. The next stage is Inference by using the rules (if – then) and the Deffuzification process to change the results of the inference stage into output values. The last is the process of stabilizing the ship with a Thruster dc motor. When the system is activated, it has a time of 0.518 seconds faster to steady state than the deactivated system with a roll tilt of (plus) 11°. On the roll tilt of (plus) 20° the highest PWM rotation is 1600µs with a time of 9,342 seconds to steady state and the roll tilt is (plus) 11° with the highest PWM of 1500µs with a time of 4,335 seconds. Based on this research, the Fuzzy Method can control the stability of the Autonomous Submarine Surface Vehicle ship.

The compaction method of powder metallurgy technology is an important process in influencing the density and hardness of the resulting product. This study aims to determine the effect of a one-way compaction method compared to a two-way compaction method on the density and hardness of the resulting composite product. The experimental method for making aluminum matrix composites with silica sand reinforcement applies a compaction pressure of 4500 Psi. Mixing utilizing mechanical alloying used a horizontal ball mill machine. The density test refers to the Archimedes principle with the ASTM B962-17 standard, while the Rockwell Brinel hardness test uses the ASTM E110-14 standard. The results of the sample density test of the two-way compaction method of compaction showed a higher value compared to the sample density of the one-way compaction results, respectively; values of 2.132 g/cm3 and 2.119 g/cm3. The hardness value of the sample resulting from two-way compression compaction also has a higher value than the sample hardness resulting from one-way compression compaction, respectively; worth 43.67 HRB and 36.78 HRB. Furthermore, based on the results of microstructural analysis, the interlocking bonding occurs in composite samples with two-way compaction. It is also better than the interlocking mechanical bonding in composite samples resulting from one-way compaction.

An automatic gate is a door whose operation process runs automatically using a remote drive tool, but when combined with IoT elements, it means that users can control the automatic gate using a cell phone or mobile phone. The purpose of this research is to create a prototype of an automatic gate control system based on the Internet of Things (IoT). The method used in the current research is the prototype method. The results in this study were tested to determine the range. Testing is done using an adapter connected to a power supply. The testing process is carried out by observing the movement and response of the servo motor when controlled via a smartphone and the stepper motor when the Ultrasonic sensor detects an object less than 5 cm. The conclusion of this research is that at a distance of 1 to 19 meters, the gate lock can still be controlled properly. While at a distance of 20 meters when the gate lock is open, the gate opens and closes. This is because the WiFi signal cannot be captured properly by the central controller of the circuit at a distance of more than 19 meters.

The development of the Internet has resulted in an increasing variety of cyber crimes. Cybercrime is closely related to digital evidence, so cybercriminals tend to delete, hide, and format all collected data to eliminate traces of digital evidence. This digital evidence is very vital in proving at trial, so it is necessary to develop applications to secure digital evidence. This study aims to compare the results of cloning and hashing in securing digital evidence and evaluate the performance of a digital forensic application developed under the name Clon-Hash Application v1 compared to applications commonly used by investigators including Autopsy, FTK Imager, md5.exe in terms of its function, the result, CPU usage. The results of the research conducted show that the cloning process is perfectly successful, as evidenced by the hash value results which are the same as paid applications and there are even several other applications that have not been able to display the hash value. Hash values in the Clon-Hash v1 application also vary from MD5, SHA1, and SHA256 which do not exist in other applications. Applications developed are better in terms of function, results, and CPU usage.

The need for electricity is increasing along with population growth. The main electricity supply (PLN) is not always continuous in its distribution, so alternative power is needed, namely generators. The ATS (Automatic Transfer Switch) system can transfer the voltage source to the load. The ATS system is equipped with IOT in the form of a Blynk application on Android which functions as a controller and can send ATS damage notifications. This research was conducted to meet the electricity needs. Users can monitor, control and maintain the ATS system in the event of a breakdown. The method in this study uses a quantitative method, namely data collection by testing the ATS system and testing the IOT Blynk application function as a notification of damage to the ATS system. The result of transferring the PLN voltage to the generator is only 7 seconds and 3 seconds vice versa. There was damage to the lamp cable 1 time, the relay 1 time, and the fan cable 2 times. The results of measuring the current and voltage of the PLN source: lamp load 0.02A, 3.4V; fan 0.04A, 3.5V; AC motor 0.04A, 4V. Generator current and voltage measurements are as follows: lamp load 0.02 A, 9.1V; 0.03A, 9V fan; AC motor 0.05A, 4.5V.
随着人口的增长，对电力的需求也在增加。主电源(PLN)在其分布中并不总是连续的，因此需要替代电源，即发电机。ATS(自动转换开关)系统可以将电压源转换为负载。ATS系统以Blynk应用程序的形式配备物联网，作为控制器，可以发送ATS损坏通知。这项研究是为了满足电力需求。用户可以在发生故障时监视、控制和维护ATS系统。本研究方法采用定量方法，即通过测试ATS系统收集数据，测试IOT Blynk应用功能作为ATS系统损坏通知。将PLN电压传输到发电机的结果仅为7秒，反之则为3秒。灯电缆损坏1次，继电器损坏1次，风扇电缆损坏2次。测量PLN源电流和电压的结果:灯负载0.02A, 3.4V;风扇0.04A, 3.5V;交流电机0.04A, 4V。发电机电流和电压测量如下:灯负载0.02 A, 9.1V;0.03A, 9V风扇;交流电机0.05A, 4.5V。

The suspension must provide comfort and safety to the vehicle. Therefore, it is necessary to analyze the load's effect on the pressure distribution on the axle so that the spring strength from the sideload force can be simulated. This study aims to analyze the sideload force of type C suspension springs using FEM. Spring variations are the number of different threaded coils, namely 11, 12, and 13. In the FEM simulation, the spring is given a load until 50mm, 100mm, 150mm, 200mm, and 250mm displacement occurs. The loading spreads to the X, Y, and Z axes. Each direction of the axis is measured by the pressure that occurs. The results showed that the pressure values that occur on the X, Y, and Z axes decreased with each increase in the number of screw coils. The lowest X-axis pressure reduction occurs in thread 12 at 63%. Meanwhile, the pressure on the Y axis decreased by 27% on the spring screw 12. The highest decrease in pressure on the Z axis occurred by 34% on the spring screw 12 compared to the spring screw 11.
