<![CDATA[Mechanical properties of Fused Deposition Modelling (FDM) 3D-printed products are a top priority in prosthesis manufacturing. Damage to 3D-printed products is often caused by the low mechanical strength when subjected to loading. Many parameters can influence the strength of the printed product during the process, including the infill pattern and line width. The infill pattern and line width serve as benchmarks for product quality, making it important to understand the impact of printing parameters to achieve optimal product strength. This study aims to analyze the mechanical properties of 3D-printed products through tensile testing with variations in infill pattern and line width. The method used to determine the mechanical properties is tensile testing. The tensile test samples were made using a Creality Ender 3 Pro 3D printer. The printing parameters were varied with three patterns: cubic, line, and triangle, as well as two infill line widths: 0.4 mm and 0.5 mm. The tensile test results showed significant differences in the variations of infill pattern and line width. The highest tensile strength was obtained with the line pattern and 0.5 mm line width, with an average tensile strength of 28.85 MPa, while the lowest value was observed with the cubic pattern and 0.4 mm line width, with an average of 27.63 MPa. These findings can serve as a valuable reference in the printing of prosthetic products using FDM 3D printing]]>

<![CDATA[Industry 4.0 is bringing about a rapid advancement in technology, particularly in the military industry. This robot was designed to reduce danger to TNI members while monitoring military operations more swiftly and safely. The application of IMU sensors for acceleration movements, measurement of control system error values, and trajectory tracking with multiple pathways are the three modes of the robot control system observed in this study. We assess each of these modes using an analytical observational method. In addition to an MPU 6050 ultrasonic and gyro sensor to detect movement using an accelerometer and gyroscope, the robot is equipped with a rotational encoder sensor to link the DC motor rotation. The PID control approach uses inverse kinematics to regulate the DC motor. The exam is administered on a track that has squares, triangles, and circles as obstacles. According to test results, the tachometer's inaccuracy rate in RPM is about 1.2% higher than the rotary encoder. The movement success percentage for the omni-wheel robot is 89.31%. Square trajectories have an average error rate of 11%, circular trajectories of 15%, and triangular trajectories of 4.17%. The motor rotation speed is most stable along the triangle path. Overall, this study demonstrates the accuracy and speed with which a mobile omni-wheel robot equipped with a control system can peek. This could raise military operations' level of efficiency and safety]]>

<![CDATA[Coal mining activities often produce acid mine drainage characterized by low pH values below 5 and high concentrations of heavy metals including iron (Fe). If the water is not managed properly, it can impact the environment due to the influence of acidity and high concentrations of dissolved metals. This research aims to utilize the combination of activated limestone and fly ash by heating at 110°C for 3 hours for acid mine drainage treatment, namely neutralizing pH and adsorbing heavy metal Fe. The selection of adsorbent materials was based on economic considerations, abundant availability, and utilization of fly ash waste. The method used was batch adsorption experiments with contact times of 30 and 60 minutes. Acid mine drainage from coal mine with initial pH 4.55 and Fe metal concentration 7.58 mg/L. The adsorbent combination of limestone and fly ash in the ratio of 1:1, 1:2, and 2:1. From the experimental results, it was obtained that the adsorbent combination was able to neutralize pH up to 6 and remove Fe up to 1.35 mg/L was the ratio of 1:2 with a stirring time of 30 minutes. So it can be concluded that adding fly ash dose 2 times compared to the dose of limestone is more effective to raise the pH value and remove Fe heavy metal, because the higher the dose given, the more ion adsorption sites will be available]]>

<![CDATA[Kerupuk Ikan Tenggiri Cap Kuda Laut is one of the fish-based cracker industries. The industry is located at Pangkalan Brandan, North Sumatra, Indonesia. The fish-based cracker industry employs 15 workers and six workstations, which include fish processing stations, fish grinding stations, kneading stations, printing stations, frying stations and packing stations. According to the observations, there is an unequal division of worker, which can result in an inappropriate workload for the worker. This study aims to analyze workers' workloads as a basis for determining the optimal number of workers. The full-time equivalent (FTE) method simplifies the measurement of work by aligning the number of people required to complete a specific job with the hours of workload. The study's findings revealed that one worker at the grinding stations had an overload, three workers in fish processing, two workers in kneading, three workers in frying and printing had normal workloads. Also at the packaging station there are 3 workers with an underload]]>

<![CDATA[As technology advances, one issue that needs to be taken into account is the consumption of power resources as one of the supports. Technology use needs to be balanced with resource management for electricity use. Furthermore, there is electrical energy waste due to the community's growing requirement for electricity usage. Changes must be taken, such as utilizing energy-saving technologies or moving to ecologically friendly items, to help reduce the usage of electricity resources. Creating applications that are eco-friendly and encourage energy savings is one way that many application developers are now addressing the issues at hand. One such way is by utilizing smart home technology (Smart Home). The design thinking methodology is applied while creating interface design, specifically in the areas of UI and UX design. Every step of the design thinking process—empathize, define, ideate, prototype, and test—will encounter loops indefinitely until a specific circumstance is satisfied. Figma is the tool used in this application to build UI/UX design. By keeping an eye on devices that are no longer in use and tracking potential cost savings, the application design outcomes should be able to lower the use of electrical resources.]]>

<![CDATA[The study of information security methods to prevent unauthorized parties from reading it is known as cryptography. The Caesar Cipher method is a low-tech yet well-established cryptography technique. One of the earliest and most basic cryptographic methods is the Caesar Cipher, which substitutes a different letter with a specific alphabetic difference for each letter in the text. The Caesar Cipher is simple to comprehend and use, but it has a lot of flaws that leave it open to frequency analysis and brute force attacks. The purpose of this study is to use the Google Colab tool to examine the cryptographic security of the Caesar Cipher technique. In this study, Google Colab—a platform that offers a robust and user-friendly Python programming environment—was utilized to construct and evaluate the Caesar Cipher algorithm. This study design combines an experimental strategy with a descriptive method. The Caesar Cipher technique is put into practice, encryption and decryption simulations are run, and character frequency analysis and brute force assaults are used to analyze security flaws. The study's findings demonstrate that the character distribution pattern is preserved when character frequencies in the original and encrypted text are seen, making it simple for attackers to use frequency analysis to crack the password. This suggests that, in the context of high information security, the Caesar Cipher should not be used. Shift passwords are therefore inappropriate for use in contemporary security applications due to their serious flaws]]>

<![CDATA[Due to environmental changes, ensuring access to clean water is challenging for many regions. This study examines how wind speed influences seawater evaporation rates in a desalination system. Conducted indoors, the research varied wind speeds (0.6 m/s, 0.7 m/s, and 0.8 m/s) while maintaining a consistent temperature. A modified window Air Conditioner (AC) served as the evaporation unit, with its condenser immersed in water to utilize released heat, and its evaporator used as a condenser. Water temperature was maintained at 60-70°C. Results demonstrated a significant increase in evaporation rates with higher wind speeds. The strong correlation between experimental and theoretical results underscores wind speed as a critical factor in enhancing freshwater production efficiency from seawater. These insights inform the design of more effective desalination systems, offering potential solutions to water scarcity challenges in vulnerable regions]]>

<![CDATA[Salah satu komponen paling penting dari upaya penyelamatan sandera adalah kesepakatan tentang pembebesan sandera. Kesalahan petugas dalam mengambil tindakan selama proses negosiasi dapat membahayakan keselamatan personel dan petugas serta korban yang disandera. Kurangnya komunikasi sering menyebabkan konflik yang berbahaya yang dapat menghambat penyanderaan. Untuk mengatasi masalah ini, kami merancang robot negosiasi khusus yang dipersenjatai untuk memastikan keselamatan dan keamanan petugas dalam menjalankan tugas, baik dalam situasi perang maupun operasi pembebasan sandera. Dengan memiliki senjata, petugas yang bertanggung jawab atas keselamatan korban dapat melakukan tugas mereka tanpa mengorbankan keamanan pribadi mereka. Robot militer ini memungkinkan negosiasi dan pemantauan tanpa mengancam nyawa, memberikan pendekatan yang lebih efisien dan aman. One of the most important components of hostage rescue efforts is an agreement on hostage release. Mistakes by officers in taking action during the negotiation process can endanger the safety of personnel and officers as well as victims being held hostage. Lack of communication often leads to dangerous conflicts that can hinder hostage taking. To overcome this problem, we designed a special negotiation robot that is armed to ensure the safety and security of officers in carrying out their duties, both in war situations and hostage release operations. By having a weapon, officers responsible for the safety of victims can carry out their duties without compromising their personal safety. These military robots enable negotiation and monitoring without threatening lives, providing a more efficient and safer approach. Additionally, the robot's ability to operate autonomously with the help of artificial intelligence allows for quicker assessment of the situation and more appropriate responses, thereby increasing the chances of success of a rescue mission without increasing risks for the humans involved. The robot is also equipped with advanced sensors and machine learning algorithms that can detect changes in a hostage taker's behavior and body language, providing valuable information to the negotiation team to devise more effective strategies. Thus, the implementation of this technology not only increases the security and efficiency of military operations, but also paves the way for further innovation in the use of robotics and Artificial Intelligence in various aspects of defense and security]]>

<![CDATA[The use of two-wheeled motorcycles is quickly increasing in Indonesia. This is because two-wheeled motorcycles are a versatile, economical, and simple mode of transportation for daily purposes. Aside from being a mode of transportation, two-wheeled motorcycles are also utilised to transmit art through modification. The chassis of a two-wheeled motorcycle is one of the components that can be adjusted. The chassis is a frame composed of iron or steel that supports the vehicle's weight and load, including the engine and occupants. Chassis changes at the Hummerroad repair business are done on a made-to-order basis. As a result, before making chassis alterations, it is vital to identify the desired assembly design and estimate the expenses involved. This study attempts to: (1) learn about the implementation of Design for Assembly (DFA) on two-wheeled motorcycle chassis at the Hummerroad Workshop. (2) Determine the effect of the DFA approach on the assembly costs of two-wheeled motorcycle chassis at the Hummerroad Workshop; (3) Determine the effect of the DFA method on the design efficiency of two-wheeled motorcycle chassis at the Hummerroad Workshop. This study employs DFA to create a customised two-wheeled motorcycle chassis. The study's findings suggest that labour costs are reduced by IDR 200,000, materials are reduced by IDR 500,000, assembly time is reduced by up to 1.39 hours, and assembly efficiency is increased to 14% per item. This demonstrates that the DFA method can serve as an option for product design and development.]]>
