Time Schedule is used as a guide and control tool for work execution time and productivity of workers, work tools on the project. In terms of productivity control, there are several aspects involved in the monitoring system, such as materials, tools, resources, and scheduling of project activities. Scheduling is the arrangement of resources to complete tasks in achieving targets. by involving components of activities, and time, In order to determine the optimal scheduling and budget. in accordance with time and cost limitations, this study uses the PDM (Precedence Diagram Method) method and the Crashing method through alternative scheduling with the addition of overtime of 1 hour, 2 hours, and 3 hours and knowing the acceleration cost. for each alternative. The results of the acceleration alternative with optimal costs are, alternative 1 adding 1 hour of overtime, the total cost decreased by 0.19% to Rp 3,067,337,201, -. This means that alternative 1 saves costs of Rp 5,984,598, - and is estimated to be one day faster to 119 days.

Infrastructure development in Jombang Regency has increased, after the city returned to normal from the Covid outbreak over time. The natural gem subsidized housing project was built on an area of ​​7,410 m2. This landed house was built with Type 30/60 with a total of 71 housing units. This project was built by PT SAMI KARYA. In this research, data collection was obtained from developers such as weekly reports, daily reports, work schedules, RAB, and actual costs. In 2023, demand for houses in Jombang Regency will increase drastically because there are still many people who need a place to live. The methods used are Return of investment, Internal rate of return and Benefit cost ratio. The ROI calculation method is concluded to be still in profitable status as a long-term investment and can be used to invest in subsidized housing development projects with an ROI value above 16.19% as a return on investment parameter, but after carrying out a trial calculation, a profit value of 389 is obtained. % and of course achieve, even exceed the target.

Land work (land clearing) in the Bunda Asri housing development project was carried out to meet the contours of the land so as to reach the planned contours, according to housing project data the volume of excavation work (cut) was 374,758.15 m³ and heap (fill) was 323,320.39 m³. The volume of excavation (cut) and embankment (fill) is divided into five sections of the earthwork area with a duration of work completion of 90 calendar days. Time constraints are the reason for project or work activities to be right on plan. Scheduling in this study uses the precedence diagram method (PDM) and is assisted by Microsoft Project software. A network that has definite dependencies and can be used in projects with overlapping activities between one another's work is called PDM. The results of the research analysis used the PDM method for the construction of Bunda Asri housing, namely 81 calendar days. which is faster than the estimate of the housing developer which lasted 90 calendar days. This happened because the grouping of work with a work breakdown structure and predecessors reduced the duration time and did not precede each other among other works.

The Kabuh – Tapen thruway is included within the category of Course III Collector road type which may be a interfacing street between Kabuh and Tapen streets. In this ponder, the point was to get the esteem of the harm list along the Kabuh - Tapen street. as a work reference and sort of street harm dealing with. Analysts will utilize the PCI and Bina Marga 1990 strategies as a reference. From the examination of the condition of the Kabuh – Tapen street segment on unbending asphalt at STA. 0+000 – 7+340 based on the Asphalt Condition Record (PCI) strategy, a esteem with an normal of 99% is gotten, demonstrating that the asphalt is in exceptionally great condition. On the adaptable asphalt at STA. 7+340 – 9+234, an normal esteem of 40% is gotten, showing that the street asphalt is in a awful condition. The comes about of the Bina Marga strategy on unbending asphalts gotten a priority order esteem of 7 so that the street is included within the schedule support program, whereas on flexible asphalts a need arrange esteem of 3 is gotten, hence it is included within the street enhancement program.

The improvement of the Cukir-Jombang road section requires heavy equipment. There is an increase in the road section at the STA. 0+000-STA. 0+936 and STA. 1+912 – STA. 2+790. In order to obtain cost and time efficiency, it is necessary to analyze the productivity of heavy equipment. This study uses the field productivity method with the aim of knowing the maximum productivity of heavy equipment and asphalt costs starting from STA 0+000 to completion. The results of this study obtained the rental time of heavy equipment for 8 hours with the number of each heavy equipment Asphalt Finisher 2 units, Dump Trucks 20 units, Tandem Roller 3 units, Pneumatic Tire Roller 2 units, Asphalt Sprayer 1 unit. Meanwhile, the cost of renting heavy equipment is IDR 4,180,000.00 for Asphalt Finisher, IDR 34,200,000 for Dump Trucks, IDR 5,700,000.00 for Tandem Rollers, IDR 3,800,000 for Pneumatic Tire Rollers, and IDR 532,000 for Asphalt Sprayers.  

Beton pracetak merupakan suatu teknologi konstruksi dimana pada saat proses pendesainan maupun pembuatan dilakukan secara fabrikasi pemasangannya sendiri harus diawasi oleh tenaga ahli karena pada saat proses penyambungan elemen pracetak tidak boleh salah supaya sambungan antar struktur pracetak jadi solid dan tidak ada keretakan, bangunan rumah susun pondok pesantren Darusa’adah di Kabupaten Kebumen Jawa Tengah merupakan bangunan yang didesain menggunakan sistem pengecoran di lokasi, elemen struktur balok dan pelat yang akan dimodifikasi ke elemen pracetak. Sistem struktur yang akan di pakai pada proses analisis perhitungan bangunan gedung adalah Sistem Rangka Pemikul Momen Khusus (SRPMK), perencanaan struktur bangunan gedung ini akan mengacu pada peraturan SNI 2847-2013, SNI 1727-2013, SNI 1726-2012 dan SNI 7833-2012, sambungan yang akan dipakai untuk penyatuan antar elemen pracetak adalah sambungan basah. Berdasarkan perhitungan modifkasi struktur didapatkan hasil untuk Tebal Plat = 14 cm untuk perhitungan balok G1.1 didapatkan dimensi 25cm x 45cm, dan G1.2didapatkan 25cm x 50cm untuk perhitungan kolom K1 didapatkan hasil dimensi 50cm x 30cm dan untuk kolom K2 40cm x 30cm, sedangkan pada perhitungan sambungan antar struktur pracetak didapatkan hasil untuk konsol pendek dengan dimensi 55 cm x 30 cm x 30 cm dengan jumlah tulangan utama 7 D16 sedangkan Tulangan sengkang / pengikat 4 D13 dan untuk tulangan stud plat ke balok di dapatkan hasil D10 – 150 mm.
