Abstract

Ragam program studi yang ada di Perguruan Tinggi patut untuk diperkenalkan sejak dini kepada siswa-siswi SMP. Adik-adik di SMP Jame Pekojan diharapkan memiliki wawasan dan tatanan dalam menggapai masa depan di bidang akademik, lalu dapat berlanjut ke dunia kerja seuai dengan keinginan, kemampuan, minat, dan bakat. Beasiswa merupakan salah satu solusi bagi adik-adik yang ingin melanjutkan pendidikan ke Perguruan Tinggi. Guna mendapatkan beasiswa, adik-adik di SMP Jame Pekojan perlu mempersiapkan diri, berupaya lebih giat, dan berprestasi. Penelitian adalah salah satu dari ragam aktivitas yang berada di dunia Pendidikan Tinggi. Topik penelitian kian beragam dan kian spesifik, aktivitas penelitian juga patut untuk diinformasikan kepada adik-adik siswa-siswi. Penelitian juga adalah jalan yang memudahkan untuk medapatkan beasiswa. Diharapkan dengan penyuluhan kali ini dapat meningkatkan wawasan adik-adik siswa-siswi di SMP Jame Pekojan mengenai arti penting dan manfaat Pendidikan Tinggi dan Penelitian di masa yang akan datang.Kata Kunci: Pendidikan Tinggi, Perguruan Tinggi, Penelitian, Beasiswa

Abstract

In this study, a copper (Cu) coated steel surface’s dynamic contact angle and corrosion rate was compared to the bare steel and stearic acid modified surfaces. Various steps of surface treatment have been performed including electrodeposition of Cu, CuO formation from H2O2 immersion with stearic acid modification to obtain dynamic contact angle and the corrosion rate data. The Cu-coated steel’s dynamic contact angle was increased as it implied the surface after Cu treatment was more hydrophilic than the bare steel, with sliding angle and contact angle hysteresis of 54.9o ± 2.39o and 39.5o ± 1.91o, respectively. However, corrosion test measurements by using a mass loss method to quantify the corrosion rate showed that Cu-coated steel and stearic acid-modified Cu-O coated steel had no remarkable difference in corrosion rate. It was found that the Cu-coated steel and stearic acid-modified Cu-O coated steel had corrosion rate eight times slower than the bare surface.

Abstract

We present the characteristics and mechanical strength of rGO-AgNPs nanocomposites in PLA-based 3D printing. The nanocomposites are characterized using X-ray diffraction and UV-Vis spectroscopy. The XRD spectrum reveals diffraction peaks at 38.14°, 44.30°, 64.50°, and 77.42°, corresponding to the (111), (200), (220), and (3111) planes of the Ag crystals, respectively. Surface observations under the microscope for pure PLA and PLA rGO-AgNPs showed that the surfaces of the samples were uniformly distributed. The results of 3D printing indicated that the 0.10 g rGO-AgNPs nanocomposite particles were evenly distributed, although digital microscopy confirmed the presence of a few small particles that were not uniformly distributed. Tensile tests demonstrated that rGO-AgNPs exhibited higher tensile strength compared to pure PLA. Tensile strength increased as the quantity of rGO-AgNPs decreased. Young's modulus results, ranging from pure PLA to rGO-AgNPs, consistently showed an increase, with the highest Young's modulus measuring 7624.45 kPa. Therefore, specimens containing rGO-AgNPs displayed a greater modulus than others, indicating that rGO-AgNPs enhanced the mechanical properties of PLA-based 3D printing.

Abstract

An Unmanned Aerial Vehicle (UAV) is commonly referred to as a drone or an aircraft with no onboard pilot. The drone technologies have been applied in many sectors such as military, hidden area exploration, medical, and many more. Purpose of this community service activities were to have elementary school teachers have basic knowledge of UAV. Initial discussions established with the teacher a month prior the seminar. Internal discussion more within the faculty members during office days and office hours through weekly offline meeting or via instant messaging service. There were 2 UAVs prepared for this seminar, and the school also already have drone for event documentation operational purposes. D-day seminar activities were only 2 hours on 27 November 2025 including preparation in the school classroom. Post-seminar activities were generating certificates for the resource persons also for all participants. The seminar has been successfully conducted with around 10 participants. Participants earned the basic knowledge about UAVs delivered by the resource person; this was essential to have both technical and non-technical information about the UAVs for teachers.

Abstract

Small Unmanned Aerial Vehicle (sUAV) is operated with no pilot. There has been growing improvements in drones, especially in public security, monitoring, military and disaster operations, traffic surveillance, agriculture, and many more. The purpose of this community service activities was to help junior high school students gain basic knowledge of sUAV and have opportunities to fly basic movements of the drone indoor at low altitude. There were 5 Unmanned Aerial Vehicle (UAV) prepared for this workshop. D-day workshop activities were only 2 hours on 2 October 2025 including preparation at the school. The workshop has been successfully conducted with around 30 participants. Participants had experience to fly indoor sUAVs with the mobile application as the controller and through wireless networks for connectivity, with basic maneuvers (take off/landing, forward/ backward, roll left/right, yaw left/right, and up/down), and took picture in at eye level. Total number of participants was sufficient with the supporting technologies brought to the school.
