Abstract

Evaluation of the reliability of the upper structure of the Ngada Regent's Office building in Mbay aims to determine the strength of the existing upper structure in accordance with SNI 1726: 2019 concerning Procedures for earthquake resistance planning for building and non-building structures, and SNI 2847: 2019 concerning Requirements for structural concrete for buildings and explanations. From the results of the analysis and evaluation of the cross-sectional strength of structural elements, it was found that there were 16 beams that were unsafe and needed to be strengthened, while the column and plate elements were quite strong and safe.

Abstract

Jembatan Wolowona eksisting di Kabupaten Ende terbuat dari struktur rangka baja dan rentan terhadapkorosi dan kelelahan material di lingkungan tropis lembap. Penelitian ini bertujuan untuk merancang ulangstruktur atas jembatan dengan bentang 50 meter menggunakan konstruksi pelengkung beton bertulang tipetrue arch sebagai solusi yang lebih durabel dan efisien dari segi biaya siklus hidup. Metodologi perancangandidasarkan pada analisis struktur menggunakan metode elemen hingga dengan perangkat lunak SAP2000.Kriteria pembebanan dan desain mengacu secara ketat pada standar nasional Indonesia yang relevan, meliputiSNI 1725:2016 untuk pembebanan, SNI 2833:2016 untuk ketahanan gempa, dan SNI 2847:2019 untukperancangan penulangan beton. Hasil analisis menunjukkan bahwa seluruh elemen struktur termasukpelengkung utama, sistem gelagar, dan pelat lantai memenuhi persyaratan kekuatan di bawah kombinasibeban rencana. Detail penulangan untuk setiap komponen telah ditentukan untuk memastikan kapasitas yangmemadai terhadap gaya-gaya dalam yang terjadi. Disimpulkan bahwa desain pelengkung beton bertulangmerupakan alternatif yang layak secara teknis, kuat, dan memenuhi standar. Struktur ini menawarkankeunggulan signifikan dalam hal durabilitas, ketahanan korosi, dan potensi biaya perawatan jangka panjangyang lebih rendah dibandingkan struktur rangka baja eksisting.

Abstract

Rewarangga Selatan Village is mostly located in hilly areas. The transfer of land use to settlements will of course disrupt the stability of the existing slopes. Therefore, education and assistance are needed in the form of training and technical guidance on proper slope management so that stability is maintained. The training in this service activity aims to: equip the community with knowledge about the potential for landslide-prone slopes, provide alternative efforts to mitigate community-based landslide disasters and make people aware of environmental sustainability in slope areas. The training was carried out using lecture, demonstration and direct mentoring methods. The lectures were used to convey the concepts of: (a) introduction to landslides, (b) geographic information on potential landslides in the South Rewarangga Village, and (c) community-based landslide disaster mitigation using vegetative methods. Furthermore, there was a demonstration by the service team as resource persons, namely by providing an example of planting vetiver grass for mitigation of landslides at the service location. The results of the implementation of service activities show that the success of the target number of training participants (100%), the achievement of the training objectives (80%), the achievement of the planned material targets (90%), and the ability of participants in mastering the material (75%).
