Abstract

Pemanfaatan limbah abu terbang (fly ash) mendukung material konstruksi yang berkelanjutan. Penelitian ini bertujuan memodelkan pengaruh persentase substitusi fly ash dan umur beton terhadap kuat tekan menggunakan regresi linier berganda (Ordinary Least Squares). Penelitian ini menggunakan data sekunder dari 20 observasi terdahulu (Kindangen et al., 2024), untuk mencapai efisiensi sumber daya tanpa melakukan repetisi uji laboratorium. Dalam memastikan validitas statistik terhadap heteroskedastisitas, analisis dioptimalkan dengan Robust Standard Errors (HC3). Hasil pemodelan menunjukkan bahwa secara simultan, umur beton dan kadar fly ash mampu memprediksi variasi kuat tekan beton secara akurat. Secara parsial, umur beton menjadi prediktor kuat yang meningkatkan kuat tekan secara signifikan. Sebaliknya, persentase fly ash (hingga 40%) tidak memberikan pengaruh signifikan saat umur dikontrol, mengonfirmasi keamanannya sebagai material substitusi. Model regresi robust menghasilkan persamaan Kuat Tekan (MPa) = 6,865 + 0,346(Umur) - 0,023(FA). Sebagai rekomendasi, praktisi konstruksi dapat mengaplikasikan persamaan ini sebagai pendekatan awal yang efisien untuk memprediksi kuat tekan beton tanpa harus melalui tahapan eksperimen yang panjang   The utilization of fly ash waste supports sustainable construction materials. This study aims to model the simultaneous effects of fly ash substitution percentage and concrete age on compressive strength using multiple linear regression via Ordinary Least Squares. This research utilizes secondary data from 20 previous observations (Kindangen et al., 2024.) to achieve resource efficiency without repeating laboratory tests. To ensure statistical validity against heteroskedasticity constraints, the analysis was optimized using Robust Standard Errors (HC3). Modeling results indicate that simultaneously, concrete age and fly ash content accurately predict variations in compressive strength. Partially, concrete age is a strong predictor that significantly increases compressive strength. Conversely, adding fly ash (up to 40%) does not exert a statistically significant effect when age is controlled, confirming its safety as a substitute material. The robust regression model yields the equation Compressive Strength (MPa) = 6.865 + 0.346(Age) - 0.023(FA). As a recommendation, construction practitioners can apply this equation as an efficient initial approach to predict concrete compressive strength without undergoing lengthy experimental phases

Abstract

Transportation supports regional growth and improves accessibility. A more efficient new route plan is needed in City X because population and business growth are not balanced with an adequate network of routes. The minibus (Elf) is chosen because it is easy to operate and can reach local corridors. By using ArcGIS, the Geographic Information System (GIS) is used in this study to analyze the road network, settlement patterns, activity centers, and community travel needs. The results of the analysis produce alternative routes that are more efficient and aligned with the movement patterns of the residents. It is expected that these routes will improve public transportation services in City X and support sustainable transportation policies.

This activity aims to analyze the implementation of Health, Safety, Security, and Environment (HSSE) practices as part of efforts to improve occupational safety. The OSL was conducted at PT Krakatau International Port (KIP), involving 47 cadets from the Bachelor’s Degree Program in Transportation at STIMARYO, with the target partners being the company’s HSSE management and staff. The implementation methods included field observations, structured interviews with management and HSSE personnel, and documentation review related to safety policies and their implementation. This approach enabled participants to gain a comprehensive understanding of safety policies, safe working procedures, the use of personal protective equipment (PPE), equipment inspection, and risk control systems applied in the port environment. The results indicate that PT Krakatau International Port demonstrates a strong commitment to occupational safety through the implementation of SMK3, the ISPS Code, continuous training programs, safety induction, permit-to-work systems, heavy equipment inspections, spill control measures, and incident reporting systems. Participants showed an increased understanding of the importance of safety culture and the key components of HSSE systems. However, several challenges remain, including extreme weather conditions, operational coordination in the field, worker compliance, and the potential for human error. This activity makes a significant contribution to preparing participants for professional careers with strong competencies and high safety awareness. Keywords: port safety; HSSE; safety work culture.

Abstract

The Indonesian government must support road development to ensure public safety, comfort, and economic efficiency. This study designs the flexible pavement thickness for the Primary Collector Road 1 section of Betungan–Padang Serai, Bengkulu City, with a total length of 5.41 km, using the Bina Marga 2017 Method and compares it with the AASHTO 1993 Method. Primary data were obtained through direct field observations, while secondary data were collected from the Bengkulu National Road Implementation Agency and the National Road Planning and Supervision Work Unit of Bengkulu Province. The pavement design based on the Bina Marga 2017 Method resulted in a thickness of 4 cm for AC-WC, 6 cm for AC-BC, 16 cm for AC-Base, and 30 cm for Class A aggregate base. Meanwhile, the AASHTO 1993 Method produced a pavement structure consisting of a 15 cm Laston-MS surface layer, a 15 cm crushed stone Class A base layer, and a 15 cm Class A gravel subbase. Mechanistic analysis using KENPAVE indicates that the stress and strain values from the AASHTO 1993 design are higher than those from the Bina Marga 2017 design, suggesting that the AASHTO design is more conservative. Based on the Asphalt Institute approach, the Bina Marga 2017 design demonstrates higher fatigue life and deformation resistance, making it more efficient and better suited to the material and traffic conditions in Bengkulu City.

Abstract

ABSTRAKPola pengasuhan memiliki peran penting dalam mendukung perkembangan remaja. Namun, karakteristik Generasi Z yang tumbuh dalam lingkungan digital menjadi tantangan bagi ibu dalam menjalankan pengasuhan. Selain menghadapi tuntutan pengasuhan, ibu juga menjalankan berbagai peran lain, seperti mengelola rumah tangga, bekerja, dan memenuhi tanggung jawab sosial. Akumulasi tuntutan tersebut berpotensi menimbulkan tekanan psikologis yang berdampak pada kesehatan mental dan kualitas pengasuhan. Oleh karena itu, pengabdian ini bertujuan untuk meningkatkan pengetahuan ibu mengenai pengasuhan yang adaptif bagi remaja Generasi Z serta memperkuat kapasitas ibu dalam membangun dukungan sosial. Kegiatan dilaksanakan pada 30 ibu partisipan yang memiliki anak berusia remaja. Kegiatan menggunakan metode psikoedukasi dan pelatihan peer support group. Evaluasi dilakukan menggunakan kuesioner pengetahuan melalui pengukuran pretest dan posttest. Hasil menunjukkan peningkatan sebesar 7.23 poin. Hasil uji Wilcoxon menunjukkan terdapat perbedaan yang signifikan antara skor pretest dan posttest (W = 0; p < 0,001) dengan effect size r = 0,87, yang menunjukkan efek besar. Semua partisipan berada pada kategori rendah sebelum kegiatan, sedangkan setelah kegiatan 80% peserta berada pada kategori tinggi dan 20% pada kategori sedang. Hasil tersebut menunjukkan bahwa kegiatan psikoedukasi dan pelatihan peer support group dapat mendukung peningkatan pengetahuan ibu mengenai pengasuhan remaja Generasi Z. Kegiatan ini memiliki implikasi bagi penguatan kapasitas ibu dalam menerapkan pengasuhan yang adaptif dan memanfaatkan dukungan sebaya sebagai sumber penyemangat dalam menghadapi tuntutan pengasuhan.Kata kunci: Ketahanan Mental;Pengasuhan; Remaja; Generasi Z. ABSTRACTParenting plays an important role in supporting adolescent development. However, the characteristics of Generation Z, who have grown up in a digital environment, present challenges for mothers in providing effective parenting. In addition to parenting demands, mothers often undertake various other roles, such as managing household responsibilities, working, and fulfilling social obligations. The accumulation of these demands may contribute to psychological stress, which can affect mothers’ mental health and the quality of parenting. Therefore, this community engagement program aimed to improve mothers’ knowledge of adaptive parenting for Generation Z adolescents and strengthen their capacity to build social support. The program involved 30 mothers who had adolescent children. The activities employed parenting psychoeducation and peer support group training. Evaluation was conducted using a parenting knowledge questionnaire administered through pretest and posttest measurements. The results showed an increase of 7.23 points in participants’ knowledge scores. The Wilcoxon signed-rank test indicated a significant difference between pretest and posttest scores (W = 0, p < 0.001), with an effect size of r = 0.87, indicating a large effect. All participants were classified in the low-knowledge category before the program, whereas after the program, 80% of participants were classified in the high-knowledge category and 20% in the moderate-knowledge category. These findings indicate that parenting psychoeducation and peer support group training can support improvements in mothers’ knowledge regarding parenting Generation Z adolescents. The program has implications for strengthening mothers’ capacity to implement adaptive parenting practices and utilize peer support as a source of encouragement in dealing with parenting demands.Keywords: Mental Resilience; Parentings; Adolescents; Generation Z.
