Abstract

Sand dunes located in Special Region of Yogyakarta Indonesia is a restricted caused by the heritage and there only four spread in hemisphere one of them in Yogyakara, Indonesia. To build in sand dunes area building could not be built arbitrarily. Portable and knockdown is the character of the building that could be adjust to the conditions in Sand dunes. By the observation results compact building design with cold formed steel material for the main building material is the recommendation of this case. The design is then consulted with sub-contractors who are expert in their expertise as the validation stage, it is feasible to be transformed into a real building for the specific needs. Output of this research is recommendation of portable building model in modular form, where the design recommendation has been adjusted with building requirement in heritage and restricted area, which is also an area prone to tsunamis and wind disasters, therefore the recommended building are; easy to remove, easy to disassemble (knockdown), forward tsunami load, efficient cost and time (using cold formed steel material and prefabricated GRC), eco friendly (zero waste), does not require many workers (less man power).

Abstract.Floods always come suddenly and unexpectedly, and lots of people living in the flood-prone area can be the victims. As happened on February 2, 2020, a number of rice fields, roads, and houses belonging to the residents in the Parangjoho watershed, Eromoko District, Wonogiri, with 9.8-km river length and 32.59-km2 area, was flooded due to heavy rain for some time which flushed the Eromoko area, therefore, the river flow could not accommodate the volume of water that entered and overflowed. This was what motivated researchers to calculate the design flood discharge to be able to carry out the flood control.The methods of calculating the design flood discharge in the Parangjoho watershed used the Nakayasu Synthetic Unit Hydrograph (SUH) Method and the Soil Conservation Service (SCS) Method, using the rainfall data from the Bengawan Solo Central River Region at Parangjoho Station. The rainfall data used were from 2000 to 2019.

Abstract

Kondisi tanah di Indonesia memiliki berbagai macam jenis tanah untuk tiap wilayahnya, keanekaragaman itu menjadikan setiap wilayah memiliki sifat-sifat tanah yang berbeda dan daya dukung tanah yang berbeda. Sifat tanah dan daya dukung tanah sangat mempengaruhi dalam dunia konstruksi karena fungsi tanah sebagai pendukung fondasi dari sebuah bangunan. Fondasi merupakan bagian dari konstruksi bangunan yang penting karena berfungsi untuk meneruskan beban yang disalurkan dari stuktur atas ke tanah dasar. Fondasi yang digunakan pada proyek pembangunan Gedung Pusat Penelitian, Pendidikan, Dan Kebudayaan Pp Muhammadiyah Yogyakarta adalah fondasi tiang pancang. Tiang pancang saat ini banyak di Indonesia sebagai fondasi dalam bangunan struktur seperti jembatan, gedung bertingkat, pabrik , menara, dermaga, metode pelakasanaan tiang pancang terdapat beberapa metode. Perlu dilakukan komparasi dari segi biaya dan waktu untuk menjadi pertimbangan dalam perencanaan sebuah proyek dari komparasi tersebut diharapkan penentuan metode pancang dapat tepat sesuai dengan kondisi pada daerah proyek tersebut akan dibangun. Hasil dari penelitian ini Total semua biaya untuk metode Hydraulic Static Pile Driver adalah Rp.174.842.411,97 dan untuk metode Drop hammer adalah Rp.103.463.026,27 dengan selisih antara kedua metode tersebut adalah Rp.71.379.385,70. Total waktu pemancangan yang dibutuhkan pada alat Hydraulic Static Pile Driver membutuhkan waktu 56 jam sedangkan untuk alat Drop hammer membutuhkan waktu 119 jam selisih waktu antara keduanya adalah 63 jam.

Abstract

The case of construction accident that occurred mid-2019 and seized a lot of attention in the surrounding community is a construction accident on the implementation of underpass construction project located in Yogyakarta. The underpass excavation wall in this project collapsed then led two vehicles are fall. Although the types of accidents are almost identical to each project, it does not mean that the same reason causes the accidents. Various methods can carry out efforts to prevent work accidents, one of which is with assessment method and risk analysis using Analytical Hierarchy Process (AHP) which sub indicators are determined using Fault Tree Analysis (FTA). The method conducted with a review in the site by referring to Ministerial Regulation No. 21 year 2019 about the SMKK (Construction Safety Management System) guidelines. This research was conducted to identify the factors and indicators of management of thesupervisory consultant and the contractor. They had a significant influence and contribution to the implementation of the Yogyakarta Kentungan Underpass construction project. The results of this early-stage study served into two outcomes. First, the accuracy of the implementation of construction safety management system based on the assessment of the contractor is 85.938% and the percentage level of accuracy of the supervisory consultant is 97.29%. Both percentages fall into the category of Satisfactory Implementation Assessment because the valuation range is included between 85% to 100%. Second, after analyzing the risk using AHP method, the indicator that is used as a reference priority for the construction safety system of underpass construction projects and has the highest risk level that can causean underpass project construction accident from the contractor's point of view is the sub-indicator of supporting facilities and infrastructure with a risk level value of 0.042 whereas from the supervisory consultant’ perspective is the sub-indicator about to measuring the dimensions of the road building installed in the site with a risk level value of 0.052. Keywords: Assessment, FTA, Causality, Construction Accident, AHP.

Abstract

In mid-2019, there was a construction accident during the underpass construction project in Yogyakarta. The underpass excavation wall in this project was collapsed and 2 vehicles were reported fallen. Although such accident sometimes occurs in some projects, it does not mean that these accidents are caused by the same source. Many efforts to prevent accidents have been done by various methods and one of them is an assessment by observation at construction sites referring to Government Regulation 05 2014 concerning SMK3 (Occupational Safety and Health Management System) in the Public Works Sector Construction. The details about the implementation of construction work are described in PUPR Decree No. 21 in 2019 in term of the Construction Safety Management System (SMKK) Guidelines. This research was conducted to identify factors and indicators of management consultants, supervisors and contractors who have a major impact and contribution to the underpass construction project in Kentungan, Yogyakarta. The percentage level of accuracy in the application of the construction safety management system based on the assessment of the contractor was 85.938% and for the supervisory consultant the percentage level of accuracy was 97.29%. Both percentages are included in the satisfactory category since the assessment ranges are between 85% and 100%. Based on these two assessments, an evaluation was carried out using a Fault Tree Analysis to determine the causality flow of construction accidents.
