ABSTRAK Pada umumnya, pengamanan pintu rumah saat ini masih mengandalkan kunci konvensional yang tidak dapat memberikan peringatan kepada penghuni adanya tamu yang datang. Peringatan tersebut dapat meningkatkan kewaspadaan penghuni terhadap kondisi rumah. Berdasarkan alasan tersebut, dibutuhkan sistem yang dapat mengawasi kondisi pintu rumah dan memberikan peringatan jika ada tamu yang datang. Pada penelitian ini, sistem pengawasan dan pengamanan pada pintu rumah direalisasikan menggunakan perangkat Raspberry Pi sebagai mikrokomputer dan website sebagai halaman antarmuka penghuni dalam pengaturan dan pemantauan sistem. Pintu rumah dapat dibuka dengan 2 (dua) cara, yaitu melalui navigasi pada halaman web dan melalui pengenalan wajah. Hasil pengujian menunjukkan sistem dapat mengenali wajah penghuni dan bukan penghuni serta memberikan peringatan berupa notifikasi di browser jika ada tamu yang datang.

This paper will discuss the calculation of inverse kinematic which will be used to control the 6-DOF articulated robot. This robot consists of 6 Dynamixel MX-28 smart servo with OpenCM 9.04 microcontroller. The articulated robot has been simplified to 4-DOF because there are no obstacles in the work area and no special movements are required. The calculation method uses the intersection point equation between the ball and the line, so that it can make it easier to determine the point in calculating the kinematic inverse. The experiment is carried out using the desired position as input for the kinematic inverse to produce the angle of each joint. From the angle of each joint obtained, it will be entered into forward kinematic so that the end-effector position will be obtained. The desired position will be compared with the end-effector position, and then how much difference will be calculated. From the experimental results, it was found that the inverse kinematic method which has been inverted by the forward kinematic produces the same final position.

Molds are important components in the plastic injection molding processes. Even though molds are generally made of strong and heat-resistant steel, but when used repeatedly and continuously, the mold will also experience damage such as scratches and dents caused by dynamic thermal and mechanical loading. Making new molds requires very high costs. Mold repairs using traditional welding such as laser welding and Tungsten Inert Gas welding, apart from requiring relatively high costs, also require sophisticated skills. This problem can be overcome with Micro-Plasma Arc Welding (MPAW). With this welding method, the process of melting the material and filler is concentrated at one point which prevents the spread of excess heat to the parent material. Welding on DIN 2311 low alloy steel, which is often chosen as a plastic molding material, was carried out with weld energies of 120, 132 and 144 J. The welding results were tested to determine the microstructure evolution, hardness distribution and strength values of each specimen. From the test results of materials processed through MPAW, it can be concluded that the specimen produced with a weld energy of 132 J has the most optimal microstructure and hardness distribution so that it can have strength equivalent to the strength of the original material before welding, with relatively high ductility as proven by its ability to perform plastic deformation of 7.8% or just 3.2% lower than the ability of the original material.

Digital literacy is crucial today, especially as artificial intelligence (AI) technology begins to develop. AI technology is widely discussed because it can help to improve efficiency in various fields of activity. The development of AI technology is basically aimed at improving human welfare, but there are disadvantages when AI technology is not used properly, which can harm society. To achieve beneficial outcomes and avoid the harm caused by the misuse of AI technology, it is deemed necessary to provide AI technology training to the community as early as possible. This community service activity provided AI training to students from Strada Santo Thomas Aquino High School, which has a mission that strongly supports the objectives of this training. This training activity began with an introduction to AI technology, which aimed to make students familiar with and understand the features of AI technology so that they are aware of the existence of AI around them. Students were explained how AI works, from database collection to pattern recognition, and were made aware that the use and development of AI technology must be carried out ethically and responsibly. The training method included an explanation of the importance and dangers of AI technology through presentations, discussions, and teamwork using the "Teachable Machine" application. Evaluation of activities was carried out through pretests and posttests as well as student feedback. The results showed an improvement in students' understanding of AI technology after participating in this training. The students were highly satisfied with the AI technology training provided, both in terms of the accuracy of the material explanation, the abilities of the instructors, and the benefits they received.
