Abstract: Progress and developments in the world of construction have greatly spurred the growth and development of the construction services business, especially in Indonesia. When carrying out activities, companies need human resources to achieve company goals, namely work productivity. Work productivity is a measure of input and output as well as the role of labor in the company. The factor that affect work productivity is work discipline. Discipline is an attempt to comply with the applicable regulations in the company. Employees must pay attention to the part of work discipline, especially employee absenteeism. Because work discipline greatly affects employee productivity factors. That’s why this research was conducted to determine the effect of work discipline on work productivity with case study in PT. PP (Persero) TBK. EPC Division RDMP RU V Balikpapan Project. The method used in this research uses multiple linear regression analysis with SPSS 23.0, 21 indicators that affect project work productivity of PT. PP includes employee compliance with all company regulations, and at work can improve performance. This is supported by the t-count work discipline value of 2.155 and a significant value of less than 0.05 with values of 0.044.
摘要:世界建筑业的进步和发展极大地刺激了建筑服务业务的增长和发展，特别是在印度尼西亚。企业在开展活动时，需要人力资源来实现企业目标，即工作生产力。工作生产率是衡量投入和产出以及劳动力在公司中的作用的标准。影响工作效率的因素是工作纪律。纪律是试图遵守公司中适用的规章制度。员工必须注意工作纪律的部分，尤其是员工的缺勤。因为工作纪律极大地影响了员工的生产力因素。这就是为什么本研究是通过PT.

Abstrak: Masa pandemi Covid-19 telah banyak mempengaruhi sistem perekonomian di berbagai negara termasuk di Indonesia. Salah satu cara yang dilakukan Pemerintah Indonesia untuk mengendalikan perkembangan perekonomian negara ialah dengan melakukan realokasi dan refocusing anggaran. Salah satu dampaknya terhadap penyelenggaraan jasa konstruksi adalah dapat menyebabkan keterlambatan penyelesaian proyek. Untuk mengantisipasi keterlambatan ialah dengan melakukan percepatan dengan memperhatikan faktor waktu, biaya, dan mutu, agar dapat memperoleh biaya optimum, waktu yang efektif, dan mutu yang sesuai standar. Metode penelitian yang dipakai dalam menganalisa keterlambatan dengan menggunakan critical pathmethod (CPM), dimana pekerjaan yang terkena jalur kritis dapat dilakukan percepatan. Dari beberapa item pekerjaan yang dilakukan percepatan, dengan menganalisa beberapa alternatif percepatan dari beberapa item dan menentukan nilai yang paling optimum dari beberapa opsi tersebut.Hasil analisa menunjukkan bahwa kegiatan yang termasuk dalam lintasan kritis ialah A1-A2-A3-A4-B1-B2-D1-D2-D3-E1-E2-F1. Namun yang dilakukan percepatan hanya 2 item pekerjaan yang memungkinkan terjadi keterlambatan yaitu kegiatan D2, dan E1. Lingkup pekerjaan rekonstruksi memiliki durasi normal 389 hari dengan biaya sebesar Rp. 18.577.999.000,-. Setelah dilakukan penjadwalan ulang menggunakan CPM memiliki durasi 226 hari. Alternatif penambahan jam kerja lembur dilakukan 1 kali crashing dengan durasi optimum 224 hari pada pekerjaan laston lapis aus (AC-WC) lebih cepat 0,88% dengan biaya optimum Rp 18.538.850.678,- sedangkan untuk alternatif shift kerja dilakukan 1 kali crashing dengan durasi optimum sebesar 206 hari lebih cepat 8,84% dengan total biaya sebesar Rp 18.371.275.091,-. Dari kedua kondisi tersebut, alternatif percepatan yang dipilih dalam upaya mempersingkat durasi proyek jalan adalah dengan menerapkan shift kerja. Abstract: The Covid-19 pandemic has greatly affected the economic system in various countries, including Indonesia. One of the methods used by the Indonesian government to control the development of the country's economy is by reallocating and refocusing the budget. One of the impacts on the implementation of construction services is that it can cause delays in project completion. Anticipating delays is by accelerating by taking into account the factors of time, cost, and quality, in order to obtain optimum cost, effective time, and standardized quality. The research method used in analyzing delays is by using the critical path method (CPM), where work that is affected by the critical path can be accelerated. Of the several work items that are being accelerated, by analyzing several alternative accelerations from several items and determining the most optimum value of the several options. The results of the analysis show that the activities included in the critical path are A1-A2-A3-A4-B1-B2-D1-D2-D3-E1-E2-F1. However, only 2 work items were accelerated which

Abstrak : Tanah Gambut adalah salah satu jenis tanah yang sering dipermasalahkan dalam suatu pekerjaan pelaksanaan konstruksi dikarenakan tanah gambut mempunyai daya dukung yang rendah. Salah satu yang jadi tolak ukur dalam kemampuan tanah dalam pembuatan sarana transportasi sebagai jalan yaitu nilai daya dukung tanah adalah berupa nilai California Bearing Ratio (CBR). Tujuan penelitian ini dilakukan untuk perbaikan tanah gambut dengan perkuatan pada tanah gambut dengan penambahan tanah non organik dan semen. Perbandingan komposisi tanah gambut dengan tanah non organik adalah 40%:60%. Tanah yang digunakan berasal dari yang ada di Kelurahan Kalampangan, kecamatan Sebangau, Palangka Raya Kalimantan Tengah, dengan penambahan semen 0%, 3%, 5% dan 7%. Pengujian sampel meliputi pengujian sifat fisik dan pengujian mekanis berupa berat jenis, pemadatan standar dan CBR dan melakukan perbandingan antara sesudah dan sebelum penelitian. Hasil dari pengujian laboratorium tanah gambut dengan penambahan tanah non organik dan semen 0% diperoleh nilai CBR 6,62%. Sedangkan pada penambahan semen 3%, 5%, dan 7% didapat nilai CBR yaitu 12,16%, 12,92%, dan 14,44%. Berdasarkan hasil tersebut maka dapat dikatakan Secara umum tanah gambut dengan penambahan tanah non organik dan semen menghasilkan peningkatan pada nilai CBR. Abstract : The peat land is one type of soil that is often questioned in a construction work because it has a low carrying capacity. One of the benchmarks in the ability of the soil in making transportation facilities as roads is the value of the carrying capacity of the soil in the form of the California Bearing Ratio (CBR) value. The purpose of this study was to improve peat soil by strengthening the peat soil with the addition of non-organic soil and cement. The research was conducted chemically with sample composition is 40% peat soil and 60% non-organic soil taken from Kalampangan Village, Sebangau sub-district, Palangka Raya, Central Kalimantan, with the addition of 0%, 3%, 5% and 7% cement. The research includes testing of physical properties and mechanical tests such as density, standard compaction and CBR and making comparisons between after and before the study. The results of laboratory testing of peat soil with the addition of non-organic soil and 0% cement obtained a CBR value of 6.62%. Meanwhile, with the addition of 3%, 5% and 7% cement, the CBR values were 12.16%, 12.92% and 14.44%. Based on these results, it can be said that in general, peat soil with the addition of non-organic soil and cement resulted in an increase in the CBR value.
