Abstract

Concrete is a primary construction material widely used for its high strength and durability. However, the production of cement—the main component of concrete—contributes significantly to carbon dioxide (CO2) emissions, resulting in considerable environmental impact. Efforts to develop environmentally friendly concrete materials have been made by utilizing organic waste as an additive, one of which is chicken manure. This study aims to determine the effect of adding chicken manure on the compressive strength of normal concrete. The research was conducted experimentally in the Civil Engineering Laboratory of Universitas Serang Raya using cube specimens measuring 15 × 15 cm. The concrete mix consisted of Portland cement, fine aggregate, coarse aggregate, clean water, and dried chicken manure with addition variations of 0%, 1.5%, and 3% by weight of cement. Tests were performed on concrete specimens at the ages of 3 and 7 days using a compression testing machine. The results showed that the compressive strength values at 3 days were 11.05 MPa (0%), 12.95 MPa (1.5%), and 10.15 MPa (3%), while at 7 days they were 14.15 MPa (0%), 15.05 MPa (1.5%), and 13.2 MPa (3%). The slump value decreased as the proportion of chicken manure increased—from 110 mm in the control mix to 90 mm in the 3% mix. This indicates that higher percentages of chicken manure reduce the concrete’s workability, and compressive strength tends to decrease beyond the optimum limit. The best performance was observed with a 1.5% addition, which still met the compressive strength requirement for K-225 grade concrete, suitable for non-structural applications. Overall, incorporating chicken manure into concrete mixtures has the potential to reduce organic waste and promote the development of more environmentally friendly construction materials without significantly compromising concrete performance.

Abstract

The Pandeglang–Rangkasbitung road section plays a strategic role in supporting regional mobility and economic activity. Increased traffic volume and excessive vehicle loads have the potential to degrade pavement performance, making a condition assessment necessary. This study aims to analyze the level of flexible pavement damage using the Pavement Condition Index (PCI) method and to estimate the cost of repairs. The survey was conducted through visual inspection to obtain primary data on the type, severity, and extent of damage, as well as secondary data related to road conditions and maintenance standards. The results show that the PCI value falls into the “very good” category, with damage rates of 84.3349% for patches, 97.9379% for block cracks, 99.2401% for edge cracks, 99.4570% for potholes, 99.9837% for joint cracks, and 98.7598% for longitudinal and transverse cracks. This indicates that the damage is functional in nature. The dominant types of damage include patches, potholes, block cracks, edge cracks, and longitudinal and transverse cracks. Based on the evaluation, the recommended course of action is routine and periodic maintenance with estimated costs of Rp1,392,200,000 and Rp9,725,700,000, respectively. These findings confirm the effectiveness of the PCI method as a basis for efficient and sustainable road maintenance planning.

Abstract

Provinsi Banten menyimpan paradoks pembangunan: pertumbuhan ekonomi makro yang terus melaju sementara kesenjangan antarwilayah justru semakin melebar. Penelitian ini menganalisis secara komparatif ketimpangan pembangunan antara kawasan Banten Utara meliputi Kota Tangerang, Kota Tangerang Selatan, Kabupaten Tangerang, Kota Serang, Kota Cilegon, dan Kabupaten Serang dengan kawasan Banten Selatan yang terdiri dari Kabupaten Pandeglang dan Kabupaten Lebak, menggunakan tiga dimensi indikator secara terintegrasi: ekonomi, sosial, dan infrastruktur. Penelitian menggunakan pendekatan deskriptif-komparatif berbasis data sekunder dari Badan Pusat Statistik (BPS) dan Dokumen Rancangan Awal RPJMD Provinsi Banten 2025–2029, serta merujuk pada kajian ilmiah yang telah melakukan analisis kuantitatif atas data yang sama. Hasil analisis menunjukkan bahwa Banten Utara mendominasi sekitar 91 persen kontribusi PDRB provinsi, memiliki Indeks Pembangunan Manusia yang lebih tinggi, didukung infrastruktur yang lebih memadai, dan menjadi pusat konsentrasi industri modern. Sebaliknya, Banten Selatan tertinggal di seluruh dimensi: bergantung pada sektor primer bernilai tambah rendah, mencatat angka kemiskinan lebih tinggi, dan memiliki akses infrastruktur dasar yang terbatas. Indeks Williamson yang dihitung oleh Suparta et al. (2026) dari data BPS secara konsisten berada pada kisaran 0,764–0,772 sepanjang 2020–2024, mengonfirmasi bahwa ketimpangan ini tergolong sangat tinggi dan cenderung divergen.
