Abstract

Unsignalized intersections often become critical points of traffic problems due to increasing traffic volume that is not balanced with intersection capacity, resulting in delays, queues, and potential conflicts, especially during peak hours. This condition also occurs at the Unida Intersection (Universitas Iskandarmuda) in Banda Aceh, which serves traffic movements from campus areas, residential zones, and surrounding commercial activities. This study aims to analyze traffic flow characteristics and intersection performance using the Indonesian Highway Capacity Guidelines (PKJI 2023). The data used include traffic volume and geometric conditions of the intersection, which are then analyzed based on parameters such as capacity, degree of saturation, delay, queue probability, and level of service. The results show that the highest traffic volume occurs during the afternoon peak hour, reaching 1,089 pcu/hour, with a degree of saturation of 0.65. The average intersection delay is 12.989 seconds per vehicle, with a queue probability ranging from 17.47% to 36.09%. The level of service is classified as C, indicating that traffic flow remains stable but begins to be affected by congestion. Overall, the intersection still operates adequately however, further evaluation is needed to anticipate future increases in traffic volume.

Abstract

This study analyzes the impact of compaction levels and paper pulp ratios on the compressive strength of papercrete blocks. The objective is to develop a lightweight building material that meets structural strength standards based on SNI 03-0348-1989. The base formulation combines cement and sand in a 1:3 ratio, with the sand volume substituted by paper at variations of 80%, 90%, and 100%. Density engineering was conducted by compressing the initial mixture volumes of 120%, 130%, 140%, and 150% into a standard size of 5 cm x 10 cm x 20 cm. Mechanical performance testing involved single blocks, paired blocks bonded with a 1 cm mortar joint, and conventional red bricks as a control comparison. Experimental results demonstrate that most papercrete variants qualify as structural materials within classes II, III, and IV. Only the 120PB100 sample failed to meet the standard classification. Interestingly, the standard red brick did not qualify for any strength class under the SNI framework. The highest mechanical performance was achieved by the 140PB80 variant, yielding a single-block compressive strength of 70.139 kg/cm². However, when evaluated in a paired formation, the strength of this 140PB80 sample reduced by 29.87% to 49.190 kg/cm².

Abstract

Bencana banjir bandang yang melanda Desa Tualang Baro, Kecamatan Manyak Payed, Kabupaten Aceh Tamiang, memberikan dampak serius pada sektor pendidikan berupa kerusakan fasilitas fisik dan trauma psikologis yang menurunkan motivasi belajar anak. Masalah spesifik yang dihadapi mitra adalah hilangnya perlengkapan alat tulis siswa serta terbatasnya akses edukasi yang mampu memulihkan kesiapan mental anak pascabencana. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk memulihkan kondisi psikososial, meningkatkan kembali semangat belajar, serta menjaga keberlanjutan pendidikan anak melalui intervensi darurat yang terencana. Metode yang digunakan adalah pendekatan partisipatif yang melibatkan dosen dan mahasiswa melalui tiga tahapan utama: persiapan kebutuhan logistik, pelaksanaan edukasi interaktif selama tiga hari, serta evaluasi respon partisipan. Hasil kegiatan menunjukkan bahwa distribusi paket alat tulis yang terdiri dari buku, alat gambar, dan perlengkapan sekolah lainnya berhasil memenuhi kebutuhan dasar belajar siswa. Indikator keberhasilan terlihat dari antusiasme dan partisipasi aktif anak-anak dalam sesi belajar bersama, di mana terjadi peningkatan kepercayaan diri dan pengurangan tanda-tanda trauma secara bertahap melalui pendekatan yang menyenangkan. Kesimpulannya, integrasi antara penyediaan sarana belajar fisik dan pendampingan edukatif merupakan strategi awal yang proporsional dan efektif dalam mendukung pemulihan pendidikan anak di situasi krisis.

Abstract

This study provides an understanding of the advantages of reinforced concrete in the construction of multi-story buildings in Banda Aceh. The objective of this research is to improve the efficiency of constructing the Class I Immigration Office Building in Banda Aceh by replacing the main structural system from steel to reinforced concrete. This change was carried out in accordance with the SNI 2847:2019 standard, utilizing the ETABS application for the design and analysis process.The results show that the total building weight in the existing condition (steel structure) is 1,594,043.95 kg, while using reinforced concrete increases the weight to 2,631,222.38 kg. At portal 5-5, the differences in bending moment and shear force between the steel and reinforced concrete structures are significant, with values of -2.9559 kNm and -80.0447 kNm for bending moment, and 3.5657 kN and 29.1996 kN for shear force, respectively. Additionally, the maximum lateral displacement in both X and Y directions is lower in the reinforced concrete structure compared to the steel structure. The axial force at portal 5-5 also shows an increase from -492.0887 kN (steel structure) to -949.2849 kN (reinforced concrete structure). These findings indicate that the use of reinforced concrete provides better stability, capacity, and overall structural performance compared to the steel structure
