Abstract

The 30% delay in construction progress on the Normalization and Embankment Construction project in Sei Berapit, Indragiri Hilir Regency, where as of the last week of November 2025 only 70% of the work had been completed, indicates that heavy equipment productivity has not met the planned target. This study aims to analyze the productivity of amphibious excavators and determine the effective number of equipment alternatives to accelerate project completion. The method used is a quantitative method with a case study approach, with productivity analysis based on work cycle time data, equipment efficiency, and actual production capacity from field observations. The analysis results show that in Alternative I, namely the use of two amphibious excavators, daily production capacity increased significantly to around 980,627 m³/day, so that the remaining work volume of 5,760.416 m³ could theoretically be completed in around 6 working days. This increase in productivity not only has an impact on accelerating the duration of implementation but also provides better operational flexibility in anticipating field disruptions. Compared to other equipment addition alternatives, Alternative I is considered the most rational because it reduces unproductive time, minimizes the risk of delays due to equipment damage or other operational disruptions, and remains within an acceptable daily operational cost level of IDR. 27,363,200. This finding confirms that productivity control and determining the number of amphibious excavators play a crucial role in time and cost management. Therefore, heavy equipment productivity evaluation should be conducted from the project planning stage, especially for excavation work in flooded terrain, to ensure optimal achievement of implementation targets.

Abstract

The construction project of the Pekanbaru Forestry Vocational High School building complex is planned with 330 calendar days in each job, it is necessary to carry out a productivity analysis to determine the level of productivity so that the work can run within the planned time. The first step in a building is foundation work, weather constraints, machine piles, damaged location access, the use of time study methods or knowing the time chosen to analyze productivity. The study was conducted by collecting data based on field observations to obtain the data needed to analyze the productivity of pile foundation work and comparison with the index value of the work unit price analysis on the 2016 Indonesian National Standard which refers to the Regulation of the Minister of Public Works and Public Housing number 28/PRT/M/2016 (National Index) concerning the coefficient of pile foundation work. Observations were made during the duration of the piling foundation work, namely 5 working days starting on 8, 9, 10, 12, and 15 March 2021. Based on the analysis that has been carried out, it can be concluded that the lowest field index value was obtained on the implementation of the piling work on the 15th. March 2021, which is 0.010 for the highest productivity obtained on March 9, 2021, with a productivity value of 0.056. So that the total field index value is 0.1221 which has a difference of 0.0021 from the pile foundation work index value that has been set in the national index which is 0.1200.

Abstract

Kecelakaan kerja pada proyek konstruksi sering menimbulkan kerugian besar. Selain dapat mengganggu jadwal dan meningkatkan biaya proyek. Pada lokasi penelitian, Jakarta Selatan pembangunan gedung bertingkat mengadopsi desain fasad modern yang dilengkapi dengan elemen tambahan berupa second skin. Kecelakaan paling serius dalam periode tersebut terjadi pada 16 September 2025. Seorang pekerja mengalami cedera berat akibat terjepit rangka baja hollow saat proses pemasangan panel vertikal. Penelitian ini bertujuan untuk mengidentifikasi potensi kecelakaan kerja dengan metode pembuatan Job Safety Analysis (JSA). Metode penelitian yang digunakan adalah dengan menganalisis potensi bahaya dan resiko dan membuat Job Safety Analysis. Potensi bahaya yang tertinggi adalah mekanis dan listrik. Potensi resiko kecelakaan kerja yang memilki efek rusak terkecil adalah terbentur material sebesar 6 poin (L) dan efek rusak terbesar adalah bagian tubuh terpotong oleh alat pemotong besi sebesar 12 poin (M). Kesimpulan kecelakaan terjadi akibat pengawasan terhadap potensi bahaya belum optimal. Kata kunci: Kecelakaan Kerja, JSA, Resiko, Bahaya

Abstract

The increase in cement production has a negative impact on the environment, so innovation in the use of concrete adhesives is needed, one of which is by utilizing fly ash waste. In order to react to form polymer bonds, fly ash requires the addition of an activator solution in the form of Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3). At cold temperatures, the hydration process and initial strength of geopolymer concrete will have difficulty being achieved optimally. So additional heat with high temperatures is needed during curing to increase the compressive strength of geopolymer concrete. This study aims to analyze the temperature and curing time on the compressive strength of geopolymer concrete. The research method is an experimental study in the Laboratory with a ratio of aggregate: binder of 65%: 35%, coarse aggregate: fine aggregate of 60%: 40%, alkali: fly ash of 38%: 62%, NaOH: Na2SiO3 of 1: 2, superplasticizer 2%, and activator molarity 12 M. The variations in temperature and curing time used were at temperatures of 60 ℃ and 90 ℃ for 6 hours, 12 jams and 24 hours. Test objects in the form of cylinders measuring 200×100 mm as many as 18 samples. The test objects will be tested for compressive strength after 28 days. The results of the study obtained the highest compressive strength value at a variation of 90℃ for 24 hours of 17.92 MPa and the lowest compressive strength value at a variation of 60℃ for 6 hours of 10.19 MPa. Based on the results of the study, it was concluded that the higher the curing temperature and the longer the curing time can increase the compressive strength of geopolymer concrete. For further research, it is recommended to vary the curing temperature above 90℃, the curing time above 24 hours and reduce the amount of air in the concrete mixture.
