Abstract

Reinforced concrete column design is the process of determining the dimensions of the columns and reinforcement required with the appropriate quality of concrete and steel so that they can withstand the planned load to work on the column. Unlike the beam design, which was based on the applied load, it is possible to determine the cross-sectional dimensions and reinforcement requirements directly from the design equation, and the column design process is iterative. A column generally experiences axial forces, shear forces, bending moments, and torsional moments. In this paper, cross-sections of reinforced concrete columns are modelled and analyzed using an android application that can be installed via the play store. The application offered by eigenplus named RCC Column Design version 2.1.12 was released on 17 September 2017. The last updated RCC Column Design application was on 25 March 2018. This paper aims to predict the cross-sectional capacity of reinforced concrete columns with variations in reinforcement diameter. The cross-sectional capacity of the column referred to in this paper is the axial capacity, moment capacity, and shear capacity. Furthermore, the value of the cross-sectional capacity of reinforced concrete columns with variations in the diameter of the reinforcement has been obtained. The values ​​obtained are proposed as predictions in this paper.

Abstract

The construction of the Bhayangkari Police Headquarters in Lamongan is a large-scale project requiring efficient time management. This study aims to analyze the application of the Critical Path Method (CPM) to optimize project completion time. By applying the CPM method, the critical path is identified, which allows for prioritizing activities that significantly affect the overall project duration. The results of this study show that the project, initially planned to be completed in 150 calendar days, can be completed in 122 calendar days. The identification of the critical path reveals 31 activities that directly impact the project's overall duration. This research provides insights into time management in construction projects and recommends optimizing scheduling and resource allocation to ensure timely project completion.

Abstract

Permasalahan pengelolaan sampah di wilayah pesisir masih menjadi tantangan lingkungan yang memerlukan keterlibatan aktif masyarakat. Desa Surodadi, Kecamatan Sayung, Kabupaten Demak merupakan kawasan pesisir yang menghadapi permasalahan sampah akibat keterbatasan sistem pengelolaan serta dampak banjir rob dan abrasi pantai. Kondisi tersebut menyebabkan pengelolaan sampah rumah tangga belum dilakukan secara terpadu dan partisipatif. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, kesadaran, dan partisipasi masyarakat melalui program pemberdayaan berbasis bank sampah. Metode pelaksanaan kegiatan dilakukan selama empat bulan melalui tahapan perizinan dan survei lapangan, persiapan program, pelaksanaan sosialisasi dan pendampingan, pembentukan kelembagaan bank sampah, serta evaluasi kegiatan. Evaluasi dilakukan menggunakan metode pre-test dan post-test untuk mengukur tingkat pengetahuan serta kepedulian masyarakat terhadap pengelolaan sampah. Hasil kegiatan menunjukkan adanya peningkatan signifikan pada tingkat pemahaman masyarakat mengenai pengelolaan sampah, dengan nilai rata-rata meningkat dari 75% pada tahap awal menjadi 95,5% setelah pelaksanaan program. Selain itu, terbentuk kembali kelembagaan bank sampah sebagai sarana pengelolaan sampah berbasis masyarakat. Program ini terbukti mampu mendorong perubahan perilaku masyarakat dalam melakukan pemilahan dan pengelolaan sampah sejak dari sumbernya. Kegiatan pengabdian ini memberikan kontribusi dalam penguatan kapasitas masyarakat serta pengembangan sistem pengelolaan sampah yang berkelanjutan di wilayah pesisir. Model pemberdayaan melalui bank sampah berpotensi untuk direplikasi pada wilayah lain dengan karakteristik permasalahan serupa.
