Abstract

Dalam sebuah proyek konstruksi, penting untuk melakukan pengendalian terhadap waktu, kualitas, dan biaya agar hasil pekerjaan sesuai dengan rencana. Penelitian ini bertujuan untuk mengetahui hasil analisis dan peristiwa kritis dari penerapan metode Critical Path Method (CPM) dalam penjadwalan waktu pada proyek pembangunan Gedung Chandra Tanjung Karang. Hasil penelitian menunjukkan bahwa perencanaan pekerjaan proyek Pembangunan Gedung Chandra Tanjung Karang telah sesuai dengan menggunakan metode CPM, waktu penyelesaian proyek dapat ditentukan dalam periode 24 minggu. Peristiwa kritis yang diperoleh, diantaranya Pekerjaan persiapan (A), Pekerjaan tanah (B), Pekerjaan Sub Struktur (C1), Pekerjaan Struktur Lantai 2 (C3), Pekerjaan Pasangan (E), Pekerjaan Kusen (G1), Pekerjaan ACP (H), Pekerjaan Pengecatan (K) dan Pekerjaan persiapan (A), Pekerjaan tanah (B), Pekerjaan Sub Struktur (C1), Pekerjaan Struktur Lantai DAK (C6), Pekerjaan ACP (H), Pekerjaan CCTV (T2), Pekerjaan Pengecatan (K) Adapun lintasan kritis (critical path) yang diperoleh dari start sampai dengan finish terdiri dari dua jalur yaitu A,B,C1,C3,E,G1,H,K dan A,B,C1,C6,H,T2,K

Abstract

Concrete quality is highly influenced by the curing process, including the type of water used, as it affects cement hydration. This study compares the effects of using seawater and freshwater on the compressive strength of concrete, with eight cylindrical specimens (four cured with seawater and four with freshwater) tested at 28 days in accordance with SNI standards. The results show that concrete cured in seawater achieved an average compressive strength of 18.88 MPa, which is higher than that of concrete cured in freshwater (14.94 MPa). This increase is presumed to be due to the presence of Ca2+, Mg2+, and SO42- ions in seawater, which accelerate cement hydration, although the Cl- content remains a concern due to its potential to cause reinforcement corrosion. This study contributes to the utilization of seawater as an alternative curing medium in coastal regions where freshwater is scarce, while emphasizing the need for further research to assess the long-term effects on structural durability.

Abstract

Urban development and rapid population growth have led to an increase in traffic volume on major roads, including the intersection of Airan Raya Street and Jatimulyo. This intersection serves as an alternative route to Metro City and is one of the key links between Bandar Lampung City and South Lampung Regency. Due to the high frequency of vehicles passing through this location, traffic congestion often occurs. The dense traffic flow affects road performance and increases the risk of both accidents and congestion. This study aims to evaluate the performance of the intersection using the PKJI 2014 Method, which takes into account factors such as capacity, degree of saturation, delay, and level of service. To determine the peak traffic volume, a traffic survey was conducted over three days — Saturday, May 10; Thursday, May 15; and Monday, May 19, 2025. Data evaluation was performed using PKJI 2014 analysis techniques. The results show that on Saturday, May 10, between 07:00–08:00, the highest traffic flow occurred, amounting to 5,938 vehicles per hour (equivalent to 2,402.2 seconds per hour after conversion). The degree of saturation (DS) was 0.8836, indicating that the intersection’s capacity needs to be reassessed to prevent more severe congestion. The level of service was categorized as C (moderate) with an average delay of 15.2298 seconds/skr and a queue probability (QP) ranging from 31.3410% to 61.8522%. This study provides a foundation for policy formulation and traffic engineering strategies at unsignalized intersections with high traffic density, supporting efforts to improve road performance and reduce congestion.

Abstract

The purpose of this study is to examine how side obstacles affect traffic flow on Jalan Ikan Sebelah in Bandar Lampung City. Roadside parking, stopped cars, cars entering and exiting, pedestrians, and slow-moving vehicles such as bicycles and pedicabs are all considered side obstacles. To assess the contribution of each side obstacle, this study uses multiple linear regression and traffic performance analysis based on the 2014 Indonesian Road Capacity Guidelines (PKJI). With light vehicles traveling at only 19.18 km/h during rush hour, the results show that the degree of saturation reached a value of 0.80, indicating a category D road service level. Vehicle parking, stopping, and entering and exiting had the greatest side obstacles, with an obstacle value of 548.8 smp/hour. These findings confirm that managing side constraints is crucial for improving the capacity and performance of road sections in areas with high social and economic activity.

Abstract

Kerusakan pada iinfrastruktur jalan merupakan salah satu permasalahan utama dalam sistem transportasi darat di IIndonesiaa, yang berdampak pada penurunan efisiensi mobilitas dan peningkatan beban ekonomi. Penelitian ini bertujuan untuk mengevaluasi tingkat kerusakan perkerasan di Jalan Pangeran Tirtayasa, Kota Bandar Lampung, dengan menerapkan pendekatan Surface Distress Index (SDI). Metode ini menilai kondisi permukaan jalan berdasarkan parameter visual seperti ukuran retakan, jumlah lubang, serta kedalaman alur roda. Pengumpulan data dilakukan melalui survei lapangan pada ruas jalan sepanjang 200 meter yang terbagi menjadi dua segmen, yaitu dari STA 4+265 hingga STA 4+465. Hasil analisis menunjukkan bahwa Segmen I memperoleh skor SDI sebesar 105 yang tergolong dalam kategori rusak ringan, sedangkan Segmen II mencatatkan nilai 35 yang termasuk kategori baik. Berdasarkan hasil tersebut, Segmen I direkomendasikan untuk dilakukan rehabilitasi, sedangkan Segmen II cukup dengan pemeliharaan rutin. Temuan ini menegaskan bahwa metode SDI efektif dalam mendukung pengambilan keputusan teknis yang lebih akurat dalam menyusun strategi pemeliharaan jalan yang terstruktur dan berkelanjutan.
