Abstract

Sidewalks are pedestrian paths generally parallel to road and higher than the pavement surface to ensure the safety of pedestrians. Sidewalk is important for pedestrians; thus, it has to meet the standards of technical requirement. This study aimed to evaluate condition of sidewalk in Kudus City, Indonesia to find out whether the existing sidewalks had complied with the technical requirement as stipulated in the Indonesian guideline for technical planning of pedestrian facilities. This was a descriptive quantitative study involving sidewalks as the sample. Data were collected through survey and analyzed quantitatively. Despite having several issues around design of the construction, the existing sidewalk in Kudus City, Indonesia had been in accordance with the provision as prescribed in the Indonesian guideline for technical planning of pedestrian facilities. Finding of the study suggested that sidewalks need for further improvement for the convenience of pedestrians, especially signposts, sidewalk accessories, direction and other relevant properties.Keywords: Descriptive qualitative study, Indonesian standard of public facilities development, pedestrians, sidewalks

Abstract

Akibat posisi Indonesia di zona Cincin Api Pasifik, risiko seismik sangat tinggi, terutama di Jakarta yang memiliki lapisan endapan tanah lunak tebal (kelas situs SE) yang memicu amplifikasi gelombang gempa. Bangunan 11 lantai dengan Sistem Rangka Pemikul Momen Khusus (SRPMK) murni mengandalkan filosofi Strong Column Weak Beam (SCWB) untuk mengarahkan kerusakan pada balok dan mencegah keruntuhan. Namun, pada fase pasca leleh, peningkatan kekuatan aktual balok (overstrength) dan degradasi kekakuan dapat menyebabkan kegagalan SCWB di lapangan. Penelitian ini bertujuan mengevaluasi pemenuhan kriteria SCWB secara eksplisit pada kondisi pasca leleh melalui analisis pushover, serta menentukan urutan pembentukan sendi plastis dan level kinerja menurut ATC 40. Metode mencakup pemodelan 3D dengan ETABS, perhitungan rasio SCWB elastis sesuai SNI 2847:2019, dan analisis static non-linear pushover dengan distribusi beban lateral berbasis ragam. Hasil verifikasi menunjukkan semua hubungan balok kolom memenuhi ΣMnc ≥ 1,2 ΣMnb dengan rentang 1,22–4,41. Analisis pushover mengonfirmasi mekanisme beam sidesway, dengan sendi plastis pertama muncul pada balok lantai dasar pada step 27 (arah X) dan step 25 (arah Y), tanpa kerusakan kolom hingga akhir. Titik kinerja dari metode spektrum kapasitas ATC 40 menghasilkan gaya geser ultimit melampaui demand desain; total drift mengindikasikan Immediate Occupancy, namun inelastic drift mengarah pada Damage Control. Disimpulkan bahwa kriteria SCWB elastis cukup protektif pada fase inelastis, namun analisis non linear diperlukan untuk menangkap redistribusi gaya dan drift plastis signifikan pada tanah lunak.

Abstract

Penelitian ini menganalisis produktivitas tenaga kerja pada empat jenis pekerjaan konstruksi, yaitu pembesian kolom struktur, pemasangan bata merah, pembesian balok dan ring balok, serta pemasangan struktur atap. Hasil analisis menunjukkan variasi signifikan antara produktivitas aktual dan produktivitas ideal. Pada pembesian kolom struktur, produktivitas aktual berkisar 14–272,29 kg/jam, sementara nilai ideal 17–356,8 kg/jam, dipengaruhi oleh faktor tenaga kerja. Pemasangan bata merah memiliki produktivitas 2,41–3,59 m²/jam, sedikit di bawah ideal 2,65–5,06 m²/jam, terkait metode kerja. Pembesian balok dan ring balok menunjukkan produktivitas 12–29 kg/jam, namun beberapa tukang mencapai 167,62–261,77 kg/jam mendekati nilai ideal 179,85–312,32 kg/jam, menandakan pengaruh koordinasi dan efektivitas alat bantu. Pemasangan struktur atap berkisar 10,45–13,18 m²/jam, lebih rendah dari standar 13,58–17,09 m²/jam, dipengaruhi metode kerja dan koordinasi. Perbandingan koefisien produktivitas aktual dengan standar Permen PUPR Nomor 8 Tahun 2023 menunjukkan perbedaan 10–78% tergantung jenis pekerjaan. Temuan ini menegaskan perlunya penyesuaian standar normatif agar mencerminkan praktik kerja nyata di lapangan.

Abstract

The development of transportation infrastructure demands structural designs that are efficient, economical, and compliant with safety standards. Columns, as primary structural elements in buildings, play a critical role in supporting vertical loads and maintaining overall structural stability. This research aims to analyze and optimize the dimensions and reinforcement of columns in the Terminal Type A Building in Salatiga to achieve material efficiency without compromising structural strength. This study is based on the existing condition of the revitalized terminal building, taking into account gravitational and seismic loads in accordance with SNI 2847:2019 and SNI 1726:2019 standards. Structural analysis was conducted using building structure software to obtain the structural response and evaluate the strength of the column elements. Optimization was carried out by varying the column dimensions and reinforcement configurations to obtain the most efficient outcome in terms of concrete volume and reinforcement weight. The results of the study indicate significant potential for material savings while maintaining compliance with strength performance standards. The optimization process offers an alternative column design that is more economical and efficient, providing valuable reference for practitioners and academics in the planning of similar building structures.
