Abstract

Effective decision making requires the implementation of a Decision Support System (DSS) that combines data, automated simulation models, and interactive visualization. This DSS plays a role in improving the efficiency of machine scheduling, identifying production lines that require overtime, and designing action plans for lines that fail to achieve production targets. The use of Macro VB Excel facilitates the acceleration of data collection and problem analysis using fishbone diagrams and FMEA, which reduces analysis time by 2.7 hours and requires additional overtime of 6.1 shifts to achieve the production target of 19,277 pcs. In the production meeting, four action plans were proposed including the creation of Standard Operating Procedures to reduce machine adjustments, routine overtime assignments, different operations for materials from certain suppliers, and standardization of parameters for each production process.

Abstract

In building construction projects, especially in the excavation stage, the use of heavy vehicles is essential and plays an important role in determining the success of apartment building construction. The production capacity of these heavy vehicles is critical to the progress of the project. The importance of production capacity analysis makes this calculation crucial. This study aims to measure the production capacity of heavy vehicles in the second phase of the Kasablanka Kuningan apartment building construction project, including asphalt finishers, dump trucks, pneumatic tire rollers, and tandem rollers. Using the volumetric method, this study calculates the volume and production capacity of heavy equipment, with results showing that productivity is in accordance with the predetermined schedule.

Abstract

Infrastructure projects, especially in flexible pavement work, are highly dependent on the use of heavy vehicles. This use is a crucial factor in supporting the success of asphalt road construction projects, where the production capacity of heavy vehicles plays a vital role in the progress of project implementation. Therefore, the calculation of production volume capacity analysis is important. The purpose of this study is to identify the production volume capacity of work on the construction of the Semarang-Demak Toll Road section 1C KM 35+400 to KM 36+400, including the capacity of asphalt finishers, dump trucks, pneumatic tire rollers, and tandem rollers. The method used is the volumetric method, which aims to calculate the volume and production capacity of heavy vehicles. The results of the analysis show that the calculation of the volume and productivity of heavy vehicles has been in accordance with the planned schedule.

Abstract

This study aims to develop a sustainability model for Muslim Small and Medium Enterprises (SMEs) in West Java by integrating the Triple Bottom Line (TBL) concept with Islamic Economic principles. The TBL approach, which includes financial, social, and environmental aspects, is analyzed to understand its implementation. This study uses a qualitative method with a phenomenological approach. Data were collected through interviews and analyzed using NVivo. The results of the study show that Muslim SMEs in West Java prioritize financial and social aspects, while attention to the environment is still limited. From an Islamic Economic perspective, sustainability is not only seen from the financial and social aspects, but also responsibility towards the environment as a mandate. Other findings show that riba, maysir, and gharar-based financial practices exacerbate financial risks and social relationships. Therefore, the proposed sustainability model integrates all three aspects of TBL with Islamic economic principles. The main contribution of this study is the development of a sustainability model based on Islamic values that offers concrete guidance for Muslim SMEs to integrate TBL principles with sharia in a practical manner. This model provides a framework to reduce dependence on riba-based financing, increase community empowerment, and environmental management according to Islamic principles. Thus, these findings can be implemented by SMEs, policy makers, and supporting institutions to promote holistic and Islamic sustainability.

Abstract

Concrete consists of cement, sand, gravel and water, with cement being the main binder that affects its quality. However, the increasing cost of raw materials and the environmental impact of lime mining and sand dredging are challenges in construction. To address this, the study proposed the use of bamboo fiber as an environmentally friendly and economical additive. This study tested the variation of 0%, 10%, and 15% pulung bamboo fiber waste on the compressive strength of concrete. The results showed that normal concrete without bamboo fiber had a compressive strength of 452 kN (fc' 26.08 MPa). The addition of 10% bamboo fiber decreased the compressive strength to 404 kN (fc' 23.32 MPa), while the addition of 15% decreased it further to 393 kN (fc' 22.68 MPa). The more bamboo fiber added, the more the compressive strength of the concrete decreased.

Abstract

Tulangan baja sering digunakan untuk menahan tarik pada beton, namun sumber daya baja terbatas dan harganya semakin mahal. Kulit tebu dapat menjadi alternatif pengganti tulangan baja karena masih minim pemanfaatannya. Penelitian ini bertujuan untuk menganalisis kuat tekan beton dengan mutu fʹc 25 MPa, mengetahui kuat lentur balok, serta pengaruh kulit tebu yang dililitkan dengan besi scrap terhadap kuat lentur dan lendutan balok pada umur 28 hari. Metode yang digunakan adalah eksperimen, dengan menganalisis balok beton yang diperkuat kulit tebu dan besi scrap. Hasil penelitian menunjukkan kuat tekan beton pada umur 28 hari sebesar 25,43 MPa. Kuat lentur pada balok dengan kulit tebu mencapai 52,13 kg/cm², lebih besar dibandingkan balok normal yang 49,88 kg/cm². Lendutan rata-rata pada balok dengan tulangan kulit tebu adalah 0,633 cm pada umur 28 hari

Abstract

Abstrak: Salah satu bagian atau aspek penting dalam bangunan struktur gedung adalah perencanaan struktur kolom dan dinding geser (shearwall dan corewall). Ada dua jenis elemen bangunan apabila ditinjau dari arah kerja yakni elemen vertikal serta elemen horisontal. Elemen horisontal yaitu plat dan balok mengirimkan beban secara aksial kepada elemen vertikal untuk kemudian beban-beban tersebut ditransfer ke pondasi yang ada di dalam tanah, Dengan menggunakan sebuah software analisis kemudian dalam melakukan pengujian berdasarkan pedoman SNI 1727:2013, maka hasil yang didapatkan adalah sebagai berikut, nilai gaya geser gempa pada arah sumbu X adalah sebesar 0,3777051 Kgf/cm2 dan nilai gaya geser pada arah sumbu Y adalah sebesar 0,4242862 Kgf/cm2 yang dapat diartikan memenuhi syarat minimum pada SNI 2012. Persentase yang didapatkan pada arah sumbu X dan arah sumbu Y adalah sebesar 100% yang dinyatakan memenuhi syarat minimum serta hasil displacement pada kolom didapat sebesar 0,11% yang memenuhi syarat maksimum pada SNI yaitu sebesar 1%.

Abstract

Project implementation requires careful planning, scheduling, and management, covering aspects such as resources, materials, equipment, natural conditions, weather, and other factors that affect project progress. This planning describes the interrelationships between activities throughout the entire project sequence and helps establish priorities. In this study, the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) were used, which differ from the approach used in the construction of the Gorontalo State University laboratory. Calculations were performed using Microsoft Project software. The analysis results indicate that six work items are on the critical path: preparation work, lower structure, upper structure, architecture, hardscape, and softscape. The estimated project completion duration is 105 days using CPM and 101 days using PERT, with a success probability of 37.37%.
