Abstrak Secara umum roket merupakan sistem yang terdiri dari wahana, propulsi, propelan, aeorodinamika dan trayektori, pemanduan dan kendali, serta telemetri dan telekomando.Agar sistem roket bisa bekerja dengan baik maka setiap subsistem tersebut harus bekerja secara sinergis untuk mencapai performa yang diharapkan.Secara garis besar pergerakkan roket ditentukan oleh sirip-sirip roket.Pada umumnya sirip kendali dapat dibagi menjadi tiga jenis, yaitu sirip kendali angguk, sirip kendali geleng, dan sirip guling.Di Indonesia sendiri melaui Lembaga Penerbangan dan Antariksa Nasional (LAPAN) mencoba untuk melakukan pengembangan teknologi kedirgantaraan di Indonesia termasuk di dalamnya roket.Salah satu produknya adalah roket RKX-300 yang diharapkan menjadi sistem wahana peluncur bagi uji coba sistem muatan. penelitian ini dilakukan dengan mensimulasikan perancangan pengendalian terhadap sirip angguk atau defleksi elevator roket untuk mengatur posisi sudut angguk roket. Untuk metode pengendalian defleksi elevator, digunakan metode Linear Quadratic Regulator (LQR) dan pole placement yang diterapkan bersama-sama pada plant. Penggunaan metode LQR saja menghasilakan hasil yang tidak optimal, kemudian digunakan metode pole placement yang memperlihatkan perbaikan pada respon transien sistem terhadap masukan step, yang selanjutnya dengan metode LQR sistem dapat mencapai nilai referensi yang diinginkan. Kata Kunci : Roket RKX-300, Sirip Angguk, LQR,Pole Placement Abstract In general, rocket is a system consist of spacecraft, propulsion, propellant, aerodynamic and trajectory, scouting and control, as well as telemetry and telecommand. In order for rocket system can work well, each subsystem must work synergistically to achieve the expected performance. the system aims to control the movement of rocket, so rocket could move according target given. In general, the control fins can be divided into three types, namely pitch fin, yaw fin, and roll fin. In Indonesia alone through Lembaga Penerbangan dan Antariksa Nasional (LAPAN) tries to make development of aerospace technology including rocket. One of its prosuct is RKX-300 that expexted to lauch vehicle system for payload testing charge.The final task is accomplished by simulating the control design of pitch fin or elevator deflection to position its nod. For elevator deflection control method, used Linear Quadratic Regulator (LQR) and Pole Placement, applied together on the plant. Using LQR method alone resulting in sub-optimal results, then use pole placement method that shows the improvement in the transient response of the system to a step input, the system further with LQR method can achieve the desired reference value. Key Word : Rocket RKX-300, Pitch Fin, LQR, Pole Placement, MATLAB,

One of the important elements of the LPG production process is the control valve. Control valves is almost 90% found in the LPG process. The size of the control valve must have a standard size so that the performance of the control valve is more optimal. Control valve CV1 is a control valve to regulate the flow of steam to reboiler in the distillation column. CV1 at the gas processing plant which is the object of research is experiencing the phenomenon of reset wind up, reset wind up is a phenomenon where the variable control valve process is unable to reach the set point at the indicating point (TIC) even though the control valve has reached 100% opening. The phenomenon of reset wind up on CV1 affects the temperature of the steam used for the reboiler. If the steam produced by the reboiler is not up to separation standard in propane distillation, then the C3 separation is not perfect and will affect the LPG yield. To improve the performance of the control valve, it is necessary to calculate the coefficient valve on the control valve and replace the internal valve parts. From this research, the coefficient value is 591, control valve body type ET-667 with diameter of 8 "and a travel indicator 2" is 567. This difference also occurs when the valve openings are 50%, 72%, 75% and 100%. The calculated coefficient valve value should be less than the data sheet. Internal part replacement was also carried out in this study, by replacing the cage on the control valve into a cage with a linear type.

Kegiatan pengabdian skim PKUM bagi Kelompok industri perabot rumah tangga dan mebel bambu dilakukan untuk meningkatkan kualitas produksi dan menajemen berbasis ekspor. Ada puluhan industri perabot rumah tangga baik skala besar, menengah dan kecil di Tegalrejo Magelang Jawa Tengah dan salah satunya tergabung di Industri Maju Mulyo. Selanjutnya puluhan industri mebel ukir bambu di Tegalrejo Magelang oleh pejabat daerah diwadahi dalam beerapa paguyuban dan salah satunya adalah kelompok Pengrajin Bambu Mas. Pengembangan kelengkapan sarana anggota industri perabot rumah tangga dan mebel ukir bambu pada usulan kegiatan diarahkan pada peningkatan kapasitas/produktitas dan kualitas produk perabot rumah tangga dan mebel bambu berukir. Dan untuk mencapai kapasitas dan kualitas produk perabot rumah tangga dan ukir bambu berbasis muatan lokal dan dengan pangsa pasar lokal dan nasional (ekspor), tim pengabdian menyusun langkah kerja atau kegiatan pengabdian meliputi pendalaman manajeman pengelolaan perusahaan terutama pada aliran bahan atau barang dan keuangan, pendalaman akan perbaikan dan penyempurnaan unit produksi, pendalaman akan perbaikan dan penyempurnaan pemasaran skala lokal dan nasional (ekspor), melengkapi showroom untuk mendukung pemasaran, pelaksanaan di industri mitra dan merumuskan indikator keberhasilan. Berdasarkan kegiatan di unit produksi, ada rancang bangun alat/mesin roll berprofil alur pada prinsipnya terdiri dari kaki atau dasar, motor listrik, meja, power transmition, hand-feed lever, ragum, klem set, landasan (blok paralel), pencekam mata bor, sarung pengurang, pasak pembuka, boring head, dan mata bor. Teknik pengerollan bertujuan untuk mempermudah, mempercepat dan menghaluskan permukaan dalam beberapa bentuk profil yakni bentuk profil yang dihasilkan berbentuk cembungan keluar maupun kedalam (tergantung pengaturan operator), menghasilkan profil permukaan yang menarik, tempat untuk menaruh penyaringan dan menambah banyaknya tingkatan perabot kukusan. Dengan adanya profil alur, produk perabot rumah tangga akan memberikan peningkatant kekuatannya, dan perabot terlihat kokoh

Rhythmic gymnastics need precision, balance, and harmonious body coordination. This study designs an automated rhythmic-gymnastics movement evaluation device based on wearable inertial and orientation sensing. An ADXL335 accelerometer sensor and an HMC5883L magnetometer sensor are integrated with an ESP32-C3 mini transmitter to acquire three-axis acceleration and heading data in real time and stream them via Wi-Fi (UDP) to a Wemos D1 Mini ESP32 as a receiver. The receiver sends data to a PC application that performs downsampling with average pooling to reduce signal density, applies min–max normalisation to harmonise scale across axes, and compares the processed test sequence against reference data. Deviations are quantified through per-parameter error computation, which is converted to accuracy and combined using predefined weights to generate an overall performance score that is displayed on an LCD/P10 panel. Experimental trials on SKJ 2012 warm-up movements show that sequences closely matching the reference pattern consistently yield high scores about 80–85, whereas intentionally incorrect executions produce substantially lower scores around 40. The proposed system therefore provides an objective, repeatable, and real-time scoring mechanism that can support teachers in evaluating movement conformity, reduce assessor bias, and enable measurable feedback for learning and training in school-based physical education.
