Colomadu is the name of a district in Karanganyar Regency, Central Java. Colomadu's economic growth can grow through the goods and services business, tourism, and industry so that an office building is planned in the Colomadu area. Because the location of Colomadu District is not far from the province of Yogyakarta, where earthquakes often occur, an earthquake-resistant building is needed to anticipate a minimum number of casualties and material losses during an earthquake. Therefore, in planning this office, a special moment resisting frame system (SRPMK) is used. The building with the Special Moment Bearing Frame System (SRPMK) is planned with the concept of Strong Column and Weak Beam (strong column and weak beam). This planning aims to plan a building structure that is resistant to earthquake loads that will be received by the structure using a special moment-bearing frame structure system and refers to the applicable requirements in accordance with SNI 2847: 2019. Earthquake loads are reviewed using the spectrum response method and structural analysis is carried out with the help of the ETABS V9.7.4 program. From the planning results, the dimensions of the bondek floor plate thickness of 140 mm, beams B1A 150x400 mm, B2A 200x400 mm, B2B 200x400 mm, B2C 200x400 mm, B2D 200x400 mm, B2E 200x400 mm, B3A 200x500 mm, B3B 200x500 mm, B4A 300x150 mm, B5A 300x150 mm, BS 150x300 mm, and columns KP 150x150 mm, K1A 200x300 mm, K2A 400x550 mm, K3A 450x650 mm, and K4A 350x500 mm.

The implementation of a project will not be separated from three factors, namely quality, time and cost. Time and cost factors can be calculated carefully and can be optimized. This needs to be done to evaluate the performance of a project, so that it becomes a lesson for the next project. This study aims to measure project performance, create optimal reschedules, optimal crash programs and calculate the time effectiveness and cost efficiency of rescheduling made in the Phase 2 Bendo Dam project. The method used in this study is the earned value and crash program with the data needed in this study is the Budget Plan (RAB), Time Schedule, Project Monthly Reports and Project Financial Reports. Then an analysis of the time and cost performance of the project is carried out, as well as calculating the optimization of alternatives for adding overtime hours and adding labor so that an optimal comparison of time and costs is obtained from the several alternatives. The results of the project performance using the earned value method in terms of costs are more accurate starting from the 18th month to the 25th month, as well as the completion time according to the planned time schedule. Meanwhile, the optimal rescheduling and crash program is adding workers with a cost efficiency of 0.66% of the total cost with a normal duration and time effectiveness of 88 calendar days.

Perkembangan dunia teknik sipil mengalami kemajuan yang sangat pesat di era society 5.0 dan gencarnya pembangunan infrastruktur di tanah air. Beton SCC merupakan beton yang inovatif yang tidak memerlukan getaran ataupun alat pemadat karna baton SCC dapat memadat sendiri. Banyaknya kebutuhan akan material menyebabkan terjadinya penambangan ilegal yang akan merusak lingkungan. Oleh karena itu, perlu adanya alternatif lain untuk mengurangi eksploitasi alam yang semakin lama akan berdampak buruk bagi lingkungan. Tujuan dari penelitian ini yaitu pemanfaatan serbuk cangkang telur dan serbuk granit digunakan sebagai subtitusi agregat halus, limbah beton digunakan sebagai subtitusi agregat kasar. Material serbuk cangkang telur berasal dari limbah cangkang telur yang telah dihaluskan dan memiliki kandungan kalsium karbonat (CaCO3) tinggi. Dalam proses produksi granit, 30% dari setiap lempengan berubah menjadi lumpur batu. Limbah tersebut sering dimuat ke dalam truk untuk dibawa pergi dan dibuang ke alam. Limbah beton adalah material sisa beton yang sudah tidak terpakai lagi untuk konstruksi.. Hasil pengujian yang dilakukan menunjukan hasil optimum masing-masing inovasi adalah 40% serbuk cangkang telur, 20% serbuk granit dan 20% limbah beton. Okamura dan Ouichi menyatakan bahwa dalam pembuatan beton SCC, agregat halus harus lebih tinggi daripada agregat kasar. Inovasi beton SCC ramah lingkungan menggunakan serbuk cangkang telur, serbuk granit, dan limbah beton mampu menghasilkan kuat tekan >41,4 MPa dan dapat menghemat biaya Rp. 407.739 /m3 dari harga beton SCC tanpa menggunakan inovasi atau setara dengan 25,92 % lebih ekonomis.

Angka kecelakaan kerja di Indonesia cukup tinggi, pada tahun 2018 data BPJS menunjukan angka 157.313 kasus, salah satunya kasus kecelakaan kerja pada pekerjaan area ruang terbatas. Pelaksanaan pekerjaan ruang terbatas harus dilaksanakan sesuai dengan standar operasional prosedur keselamatan kerja yaitu pengendalian kualitas udara seperti kandungan O2, CO, H2S, dan gas pemicu ledakan (LEL), dipastikan tidak melebihi nilai ambang batas sesuai peraturan agar terhindar dari accident. Penelitian ini dilakukan di PT Waskita Karya-Adhi Karya, KSO, pada pekerjaan terowongan pengambilan Proyek Bendungan Jlantah yang terletak di kecamatan Jatiyoso kabupaten Karanganyar. Objek yang diteliti sendiri merupakan salah satu pekerjaan konstruksi yang merupakan pekerjaan beresiko tinggi yaitu pekerjaan pembangunan terowong pengambilan yang dikategorikan sebagai ruang terbatas atau confined space. Data-data diperoleh dari data riwayat pengukuran kualitas udara menggunakan alat Gas Detector pada saat pekerjaan galian terowong intake pada rentang waktu November 2020. Hasil pengukuran kadar O2 didalam area kerja menunjukan fluktuasi antara 20,8% – 21% namun tidak signifikan dan masih dalam ambang batas normal 19,5% - 23%. Hasil pengukuran kadar CO selama masa penelitian terdapat beberapa kali peningkatan diatas ambang batas sampai dengan 38 ppm dan 40 ppm dari nilai ambang batas yang diijinkan sebesar 35 ppm. Hasil pengukuran gas H2S dan LEL tidak terdeteksi adanya gas tersebut. Kata kunci: Keselamatan dan Kesehatan Kerja, Kecelakaan Kerja, Terowongan Pengambilan, Bendungan Jlantah

Tentrem Semarang Building is one of the tallest buildings in Semarang with 4 basement floors and 17 top floors. The construction of basements in high-rise buildings is currently being carried out a lot, one of the factors is due to the limited land to be built, in general, the construction of basements is used for parking lots. The basement to be built has different depths and conditions, so it takes the right method according to the conditions in the field. There are 2 methods for implementing basement construction, namely bottom-up and top-down. In the basement structure work of the existing Tentrem Semarang Building construction project, the basement construction used the bottom-up construction method. In this study, the method will be modified using the top-down construction method. Information regarding work methods, worker productivity was obtained by interviewing field supervisors from the owner, interviews with supervisors from the main contractor and direct field observations. Calculation of costs and time is carried out by analyzing the capacity and productivity of labor and heavy equipment, comparing the normal time with the time after changes in construction methods. The results of the modification of the construction method using the top-down construction method for the basement structure of the Tentrem Semarang Building project took 510 days to complete and cost IDR 205,059,861,826. Whereas for the bottom-up method it takes 685 days with a total cost of IDR 253,609,405,225. The application of the Top-Down method to the implementation of the basement structure of the Tentrem Semarang building project is more effective and efficient than the implementation of the Bottom-Up method and produces a time effectiveness value of 25.55% and a cost efficiency of 19.14% compared to the Bottom-Up method

Improving safety at railroad level crossings is continually conducted to reduce accidents rate at railroad level crossings, especially unguarded official railroad level crossings where accidents often occur. Railroad level crossings are prone to accidents and it mainly caused by accidents that occur at level crossings. Accidents at level crossing are caused by several factors such as human error, crossing guards who are late to lower the barrier, and inferior public awareness to comply with signs at level crossings. This research is located at the railroad level crossing KM 31+988 in Taman District, Sidoarjo. The analysis result shows that the influence factors of people violating the train early warning system are the frequency of random crossings in a day which affects the committing violations with a probability value of 60.72%, and the waiting time before a train passes which takes too long promote committing violations with a probability value of 32 .7%.

ABSTRACT In this study the authors aimed to determine the effect of using beef bone aggregate as an added ingredient for sand (fine aggregate) as well as an added ingredient for making ready mix concrete. The percentage levels of beef bones used in this study were 4%, 6% and 17%. In the manufacture of the test object is done by mixing the binder (cement), sand (fine aggregate and cow bone ash), gravel (coarse aggregate) and water using the experimental method. Samples of specimens were made using cylindrical molds (molds) and treated. The concrete compression test was carried out using a press machine, the mix design plan for making concrete was planned at 30 MPa. The total test objects made in this study were 20 pieces. The results of the test object with a cow bone ash content of 4% obtained compressive strength results of 7.58MPa 8.775 MPa 11.21 MPa 10.92 MPa and 10 MPa with an average value of 9.7 MPa. From the results of the addition of 6% beef bone ash, the results were 9.79 MPa, 9.73 MPa, 8.03 MPa, 9.23 MPa and 13.36 MPa and an average value of 10 MPa, for results with an addition of 17% cow bone ash was 10.3 MPa, 18.11 MPa, 15.28 MPa, 16.53 MPa and 19.13 MPa with an average yield of 15.87 MPa Keyword: Concrete, Cow Bone Ash, Compresive masive, Aggregate.

Irrigation System Performance Index (ISPI) is often used as a parameter in making decisions about the use of irrigation canals. The increase in rice production is dependent on a good condition of physical infrastructures, including the main building, the carrier canal and the buildings on the carrier canal. Performance assessment of Physical Infrastructure and Plant Productivity in Sungapan irrigation area of Pemalang Regency indicated that the physical infrastructure performance in 2012 - 2022 was 38.42%, increasing 3.22%. While the performance assessment of Plant Productivity was 14.96%, increasing 2.99%. Based on the multiple regression analysis using simultaneous test (F), the Physical Infrastructure component was indicated to influence the plant productivity. Meanwhile, based on the partial test (t), the physical infrastructure component partially did not have a significant influence on the plant productivity
