Abstract

Kapasitas beban struktur beton bertulang eksisting seringkali tidak mencukupi untuk memenuhi standar saat ini. Hal ini dikarenakan peningkatan kebutuhan beban, ketentuan geser yang tidak memadai pada desain asli, degradasi material, atau meningkatnya kapasitas geser yang terkait dengan penguatan lentur. Penelitian ini mendemonstrasikan metode perbaikan kapasitas geser balok beton bertulang yang efektif dengan menggunakan tulangan baja tertanam. Riwayat pembebanan direproduksi dalam bentuk retak dalam rentang elastis pada balok 2000 x 150 x 200 mm, balok tersebut diperbaiki dan kemudian dibebani kembali hingga gagal dalam uji eksperimental. Hasil penelitian menunjukkan bahwa kontribusi tulangan baja yang tertanam pada inti balok RC terhadap kapasitas beban dapat signifikan. Kekakuan awal balok perkuatan tertinggi adalah 13,07 kN/mm, yaitu 69% lebih tinggi dari balok kontrol. Perpindahan beban ultimit dari balok yang diperkuat adalah 43 kN dengan lendutan sebesar 13 mm, yang lebih tinggi 53% dari balok kontrol. Perkembangan retakan selama fase beban kedua dari balok yang diperkuat identik dengan yang pertama. Retakan yang berkembang melebar saat beban meningkat dan spesimen akhirnya runtuh secara lentur. Kapasitas geser balok yang diperkuat sebesar 43,73 kN pada balok BII lebih tinggi dari balok kontrol.

Abstract

The load capacity of old reinforced concrete structures must be increased to meet current standards. This might be due to increased load needs, inadequate shear provisions in the original design, material degradation, or rising demands for shear capacity related to flexural strengthening. This research demonstrates a method that effectively repairs RC beams using embedded steel bars. Loading history was reproduced in the form of cracking within the elastic range in 2000 x 150 x 200 mm beam. The beam was repaired and then reloaded to failure in the experimental test. The results show that the contribution of steel bars embedded in the core of the RC beam to the load capacity can be significant. The highest initial stiffness of the strengthened beam was 13,07 kN/mm, which was 69% higher than the control beam, while the maximum load of the strengthened beam was 43 kN with the deflection at 13,00 mm, 43% higher than the control beam. The cracks developed during the reinforced beam’s second load phase were identical to the first, and the shear capacity increased more than the control beam.

Abstract

Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas literasi dan produksi konten digital di Pondok Pesantren Tarbiyatul Banin Dukupuntang Cirebon sebagai strategi penguatan daya saing dan peningkatan minat calon santri. Analisis awal menunjukkan bahwa pesantren memiliki potensi kegiatan dan lingkungan yang menarik, namun belum diiringi kemampuan teknis dalam pembuatan konten, strategi branding digital, maupun pemanfaatan media sosial secara efektif. Kondisi tersebut berdampak pada terbatasnya eksposur lembaga dan penurunan jumlah pendaftar dalam beberapa tahun terakhir. Melalui pelatihan branding digital, workshop pembuatan konten menggunakan Canva dan CapCut, serta pendampingan pengelolaan media sosial, program ini menawarkan solusi terstruktur untuk memperbaiki kualitas promosi pesantren. Metode pelaksanaan mencakup sosialisasi, pelatihan berbasis praktik, produksi konten aktual, serta evaluasi dan monitoring berkelanjutan. Program ini diharapkan menghasilkan kemampuan mandiri dalam produksi konten, peningkatan visibilitas digital lembaga, dan terciptanya budaya pemanfaatan teknologi yang mendukung keberlanjutan promosi pesantren. Selain itu, peningkatan keterampilan digital santri berpotensi membuka peluang sosial dan ekonomi yang lebih luas.

Abstract

The digital transformation in public sector organizations requires civil servants to adapt to ever-evolving technologies. However, technology-induced work pressure, known as technostress, may negatively impact their strategic job performance if not managed effectively. This study aims to examine the effect of technostress on strategic job performance, with digital work engagement as a mediating variable. The research involved 94 civil servants from two local government agencies using a quantitative approach. Data were collected through a structured Likert-scale questionnaire. The results revealed that technostress had a significant negative effect on strategic job performance, while digital work engagement showed a significant positive effect. Mediation testing using the Sobel test confirmed that digital work engagement significantly mediated the relationship between technostress and strategic job performance. These findings emphasize the importance of fostering digital work engagement as a strategy to mitigate the negative impact of technostress within civil service environments.

Abstract

Inequality in child health status in developing countries remains a serious public health issue, particularly because stunting not only reflects chronic undernutrition but also indicates disparities in social, economic, educational, sanitation, food security, and access to basic health services. This condition affects physical growth, cognitive development, future productivity, and the overall quality of human resources. This study aims to analyze the determinants contributing to stunting among children in developing countries and to identify relevant, comprehensive, and sustainable prevention strategies. The method used in this study is a literature review by examining various scientific articles, reports from health organizations, and policy documents discussing the causal factors and preventive interventions for stunting. The literature was selected based on topic relevance, recency of information, source quality, and its relevance to the public health context in developing countries. The findings indicate that stunting is influenced by multidimensional factors, including inadequate maternal and child nutritional intake, suboptimal infant and young child feeding practices, recurrent infectious diseases, low maternal education, poverty, limited access to clean water and sanitation, and poor utilization of basic health services. Stunting prevention strategies need to be implemented through both nutrition-specific and nutrition-sensitive approaches, such as fulfilling maternal nutritional needs during pregnancy, promoting exclusive breastfeeding, providing adequate complementary feeding, micronutrient supplementation, immunization, growth monitoring, sanitation improvement, strengthening household food security, and community-based health education. Scientifically, this study finds that stunting prevention cannot be achieved solely through nutritional interventions but requires the integration of cross-sectoral policies involving the health, education, social, food, economic, and environmental sectors. Therefore, stunting management in developing countries should be directed toward improving structural determinants and family health behaviors simultaneously so that its impact becomes more effective, equitable, and sustainable.
