Ester Klaudia Tamara — 2024-04-02

Berkembangnya suatu daerah sangat mempengaruhi pertumbuhan perekonomian, perkembangan tersebut didukung oleh berbagai sektor salah satunya sektor konstruksi. Sektor konstruksi memiliki dampak negatif terhadap lingkungan yaitu masalah limbah. Oleh sebab itu diperlukan waste management yang tepat dan efektif. Salah satu metode untuk mengetahui tingkat penerapan waste management dalam pelaksanaan proyek konstruksi adalah dengan melakukan penilaian terhadap setiap tindakan penanganan limbah dalam suatu proyek konstruksi, salah satunya dapat dinilai menggunakan metode Waste Management Performance Evaluation Tool (WMPET). Penelitian ini bertujuan untuk mengetahui implementasi waste management yang dominan dan untuk menghitung nilai seberapa efektif implementasi waste management yang telah dilakukan oleh developer. Penelitian ini dilakukan dengan menyebarkan kuesioner dan wawancara terhadap developer yang terdaftar dan memiliki keanggotaan aktif di DPD REI Kalimantan Tengah. Hasil penelitian menunjukkan bahwa indikator implementasi waste management yang paling dominan pada proyek konstruksi perumahan di Kota Palangka Raya adalah mencegah pemesanan material yang berlebihan, menggunakan material sesuai standar yang ditetapkan, dan mengurangi risiko kehilangan material selama proses pengangkutan dan penyimpanan. Nilai hasil perhitungan keefektifan waste management berdasarkan penilaian (WMPET) didapatkan sebesar 543,96 dari nilai 1000. Nilai tersebut berada pada rentang indeks 401 – 600 dan mendapat predikat buruk yang berarti bahwa manajemen limbah konstruksi pada perumahan oleh developer di Kota Palangka Raya tidak efektif untuk mengurangi limbah konstruksi maupun meningkatkan kegiatan daur ulang limbah konstruksi. Selanjutnya saran yang diberikan dari penelitian ini, diharapkan developer mempertimbangkan upaya membuat perencanaan manajemen limbah pada proyek konstruksi perumahan untuk meningkatkan keefektifan waste management karena manajemen limbah konstruksi hanya berdasarkan kebiasan dan kebijakan pekerja dalam menangani limbah, diharapkan pihak pemerintah dapat mempertimbangkan untuk mengadakan sosialisasi/pelatihan tentang manajemen limbah konstruksi kepada developer yang berguna untuk meningkatkan penerapan manajemen limbah pada proyek perumahan.

Ni Putu Silvi — 2024-04-03

The success of each job in a construction project influences the success of the project, where labor productivity factors influence the success of a project. If one project activity has problems, it will greatly affect other project activities because construction project activities are interrelated. Labor management is one of the problems that often causes delays in construction work. The lack of effectiveness of the workforce in carrying out their work makes it very difficult to obtain good productivity values. Smoking, taking breaks and eating during working hours are examples of activities that cause less productive work. Hebel wall installation work is a large volume job and requires a large amount of labor. From the description of the problems found related to labor productivity, this research will carry out an analysis of the productivity of the labor installing hebel installation and the influencing factors of labor productivity installing hebel installation on the construction of the Villa Obao 2 project on Jalan Raya Double Six, Seminyak, Kuta, Badung, Bali. This research uses the Productivity Rating method to determine the value of labor productivity in hebel installation work and distributes questionnaires to analyze factors influencing hebel labor productivity. The results of the analysis of labor productivity observed for 7 days, the average LUR value for workers installing hebel was 67.8% > 50%. Of the 10 factors influencing productivity, only 3 factors have a significant influence on productivity. These factors are the Wage Suitability factor (X3) with an influence value of 4.094, the Motivation factor (X7) with an influence value of 4.133, and the Communication Relations Factor between Employees (X9) with an influence value of 5.498.

Identifikasi Kapasitas Tampang Minimum dan Stabilitas Mulut Muara Sungai Siak Propinsi Riau

Bambang Sujatmoko — 2024-04-04

Changes in river mouth section capacity caused by instability of river mouth stability would influence flow conditions in upstream estuaries, as impacted by unsmooth drainage of river flow. Section river capacity and mouth river stability of Siak River would be evaluated by the output of tidal prism at the estuary. The tidal prism was predicted by Hecras software. Input data for hydrodynamic simulation consisted of river geometric data, river bed condition, and boundary condition (discharge and water level). The maximum daily rainfall data and Siak’s catchment parameter could predict flood discharge. Longshore sediment transport netto data could be calculated using wave depth data, wave velocity data and direction of wave around the mouth river. The results of the tidal prism calculation show that the existing cross-sectional area of the mouth of the Siak River estuary can only drain the volume of water due to discharge and tides in the 2-year return period (Amin = 3,115 m2 < A ada = 3,225 m2), while for discharge with other return periods, the capacity of the cross-section river is not sufficient. The excess discharge will flow upstream as a backwater. Siak River mouth stability is still relatively good and stable, with a stability number (S) of more than 388,0 (requirement: S > 150). The start of the backwater effect at KM+220 (60 km from the mouth of the river) caused a significant change in water level (0.94 m) due to the damming of the flow caused by the influence of tides and the bifurcation node of the river (delta).

Tantin Pristyawati — 2024-04-04

Road infrastructure has a function as one of the supporters of the development of an area. The Road infrastructure still used today is a flexible pavement composed of a mixture of asphalt and aggregate, which is heated and then compacted. Asphalt serves as a binder in the flexible pavement to maintain density and resist the weathering of aggregates caused by weather. It is an innovative additive used in concrete waste to replace rough aggregates. Adding LGA B50/30 in a base mixture is expected to be an alternative to improving the quality of the base mix and supporting the government in the use of domestic products. The study aims to determine how marshall is characterized if concrete waste is used in the AC-BC Ashburton mix as a substitute for rough aggregates and whether it meets the requirements of the Binna Marga Specification. The study was conducted experimentally with marshal characteristic parameters density, VIM (Void In Mix), VMA (Void In Mineral Aggregate), VFA (Void Filled with Asphalt), stability, and Marshall Quotient. (MQ). The Optimum Asphalt Rate used is 6.5%. The result is the density decreases with the addition of concrete waste levels, with the highest value at the 30% concrete waste level of 2,408 gr/cc. The increase in the VIM value with the addition of the concrete residue level has a higher value at a rate of 70% or 4.66%. The highest MQ is at a 50% concrete waste rate of 334.04 kg/mm. The study results show that waste concrete innovation materials can be used in Asbuton AC-BC mixtures with levels not exceeding 60%. Based on this research, concrete waste can be an alternative to natural aggregate substitutes.

Yayuk Apriyanti — 2024-04-19

Clay soil is a type of soil that has problems because it has high plasticity, a low carrying capacity, and is prone to settlement. This soil condition can be found in the Hanging Tramble, Pangkalpinang City. This study aims to determine the effect of FGD waste gypsum on clay soils, the maximum value of soil shear strength, and the minimum value of soil consolidation settlement. The stabilizing agent used in this study was Flue Gas Desulfurization ( FGD) waste gypsum with a mixture of 10%, 15%, and 20% FGD waste gypsum from the dry weight of the soil., for a total of 39 samples of the test object. Testing in this research uses Indonesian National Standards (SNI).The test results obtained the maximum value of the shear strength of the soil in the FGD waste variations of gypsum at 15%, which is 115.243 kN/m², and in the 20% FGD gypsum waste mixture, the value of the shear strength of the soil decreased by 79.634 kN/m². The minimum value for consolidation settlement was obtained from FGD waste variations (gypsum 20%), which is 0.683 cm. The minimum value obtained for consolidation settlement is influenced by the calcium content in the FGD waste gypsum, which can bind soil minerals so as to increase soil strength. It can be concluded that the maximum soil shear strength value occurs in the 15% FGD waste mixed sample variation gypsum, while the minimum soil consolidation settlement value is in the 20% mixed FGD waste mixture gypsum.

Peningkatan Workability Pasta Beton Modifikasi Dengan Pemanfaatan Abu Sekam Padi Menggunakan Superplasticizer

Rama Putra Nugraha — 2024-04-26

Infrastructure development in Indonesia is the main focus of the government, especially in the construction sector with toll road projects, airports, high-speed rail lines, and smart cities in the new capital city. Concrete is becoming the main material in infrastructure because of its high compressive strength and relatively low cost. Aggregates, especially natural and artificial, play a key role in concrete structures. The growth in demand for natural aggregates has an impact on environmental damage due to mining. Innovations using Rice Husk Ash instead of natural aggregates emerged as an environmentally friendly solution. However, it is necessary to optimize the mix design and handle workability reduction with superplasticizers. The percentage of superplasticizers used is 0%, 0.52%, 0.54%, 0.56%, 0.58% of the total use of cement. In concrete workability tests, such as Flowability, Passingability, and Viscosity, it was found that a 0.54% SCCRHA mixture showed optimal performance. The Flowability test showed a Slump Flow runoff value of 77.5 cm (SF3 category), while the J-Ring test showed a runoff of 75 cm with 2.5 cm blocking (No Blocking). The Viscositytest showed T-500 and V-Funnel times of 1.8 seconds and 2.18 seconds, respectively, with VF1 and VS1 (good filling) classifications. The results showed that this mixture achieved the most effective design with a compressive strength of 25.17 MPa, showing an increase of 13% compared to the plan mixture
