Abstract

This research employs the Finite element method to optimize the frame structure of a Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicle (UAV). The material used in this study is a unidirectional carbon fiber stacked in a specific sequence. The topology optimization process is conducted to achieve a lightweight structure whilst maintaining its integrity. The design constraint is set to reduce 50% weight and minimize the strain energy. The benchmark phase was performed while considering a previously done study to validate the proposed method. The results of this study have successfully reduced 34% (0.581 kg) weight of frame structure. First failure predicition study using Hashin criterion, shows the first failure occurred in the matrix of Ply-2 at 9000 N.

Abstract

The Industry 4.0 era mandates that school principals manage innovation to optimize learning technology. This study aims to analyze (1) the principal's innovation management strategies, and (2) the enabling and inhibiting factors for technology optimization at TK Negeri Pembina Batumandi. The research utilizes a qualitative approach with a case study design. Data were collected through in-depth interviews with teachers (IG) and school operators (IO), observations, and documentation studies. Data were analyzed thematically. The findings indicate the principal implements a dual strategy: (a) a managerial strategy, focusing on prioritizing the ICT budget and asset management systems (per IO findings), and (b) a transformational/cultural strategy, creating a psychologically safe climate for innovation and employing dialogical supervision (per IG findings). The primary enabling factor is the principal's "tech-savvy" and adaptive leadership. Inhibiting factors were identified at two levels: internal (operational efficiency of device setup and maintenance management) and external (unstable internet and electricity infrastructure). The study concludes that the principal's innovation management successfully combines systemic (budgetary) and cultural (psychological) support, yet its effectiveness remains constrained by external infrastructural challenges.

Abstract

Research on structural analysis of an unmanned aerial vehicle (UAV) is carried out. The primary material used in most structures is carbon composite. Having a high aspect ratio wing, the lugs connecting the wing and fuselage are likely to experience maximum forces during flight tests. In predicting the occurrence of deformation and stress, the finite element method is used by applying max./min. strain criteria to evaluate the structural integrity of composite wings due to the load applied on aluminum-based lugs. The evaluation shows that the current wing configuration has good structural integrity. An optimization approach is also carried out to obtain more optimum results.

Abstract

Childbirth can produce pain in post-cesarean section patients which can affect the healing process and slow down the patient's movement due to the pain, so in this study the problem obtained is the intensity of pain in post-cesarean section patients. This study aims to determine the effect of early mobilization in post-cesarean section mothers on pain intensity at the Aceh Government Mother and Child Hospital in Banda Aceh City. This study uses a quantitative research method with a quasi-experimental design with a sample of 30 people who became the intervention group. The intervention group received early mobilization intervention after post-cesarean section. The pain intensity in post-cesarean section patients was measured using a pain measurement scale, namely the Numeric Rating Scale (NRS) and using an early mobilization SOP to be taught to patients and implemented independently. Based on this study, the average pain intensity before early mobilization was 4.06, while the average pain intensity after early mobilization was 2.86, so the results of this study indicate that there is an effect of early mobilization on pain intensity in post-cesarean section mothers which is significant P = 0.000 <0.05. This study concludes that early mobilization can be used as a nursing intervention to reduce pain in post-cesarean section patients. For nursing practitioners, the results of this study can be used as a reference for developing more effective nursing interventions to reduce pain in post-cesarean section patients. Furthermore, this study is expected to serve as a reference and education for patients and their families, the Aceh Government Maternity and Child Hospital in Banda Aceh City, Bina Bangsa Getsempena University, and for future researchers.   Keywords: Early Mobilization, Post-Section Caesarean, Pain Intensity.
