Abstract

Indonesia merupakan negara dengan penduduk terbanyak ke empat di dunia dan hal ini menjadi tantangan pemerintah dalam membangun infrastruktur yang memadai. Salah satu program pemerintah dalam pembangunan infrastruktur adalah program Proyek Strategis Nasional (PSN) yang tersebar di seluruh Indonesia yang salah satunya adalah proyek bendungan. Penelitian ini dilakukan di proyek Pembangunan Bendungan Bener di Kabupaten Purworejo pada pekerjaan Paket 3. Penelitian ini dilakukan dengan konsep ISO 31000:2018 yang mengidentifikasi risiko dari sudut pandang pengguna jasa (owner) dan penyedia jasa (kontraktor) berdasarkan kemungkinan kejadian risiko dan dampak risiko. Hasil identifikasi risiko akan divalidasi oleh masing-masing pihak dan akan dilakukan penilaian oleh responden yang terlibat langsung dengan pelaksanaan pekerjaan. Hasil penilaian risiko akan dianalisis menggunakan matriks risiko. Respon risiko dari masing-masing pihak akan dilakukan dengan wawancara berdasarkan tiap variabel risiko. 11 variabel risiko dari sudut pandang pengguna jasa (owner) dan 21 variabel risiko dari sudut pandang penyedia jasa (kontraktor). Hasil penilaian risiko dari pihak pengguna jasa didapatkan risiko dengan kategori high risk sebanyak 8 risiko, kategori medium risk sebanyak 3 risiko. Sedangkan pihak penyedia jasa didapatkan risiko dengan kategori high risk sebanyak 18 risiko, kategori medium risk sebanyak 2 risiko, kategori low risk sebanyak 1 risiko. Respon risiko berdasarkan hasil wawancara didapatkan sebanyak 3 risiko yaitu risk reduction, 1 risiko yaitu risk avoidance, 4 risiko yaitu risk transfer, 2 risiko yaitu risk avoidance-transfer, dan 1 risiko yaitu risk reduction-transfer. Kemudian untuk penyedia jasa adalah 6 risiko yaitu risk reduction, 7 risiko yaitu risk avoidance, 2 risiko yaitu risk transfer, 3 risiko yaitu risk retention, 2 risiko yaitu risk reduction-transfer, 1 risiko yaitu risk avoidance-transfer.

Abstract

Proyek kontruksi bendungan merupakan salah satu proyek memiliki tingkat kompleksitas pekerjaan yang tinggi. Pelaksanaan pekerjaan galian menggunakan crawler drill pada batuan keras dirasa kurang menghasilkan angka produktifitas sesuai dengan target. Blasting adalah metode alternatif pada pekerjaan galian yang bekerja dengan cara menghancurkan suatu kesatuan batu yang memiliki volume besar menjadi partikel-partikel yang menjadi lebih kecil. Metode blasting memiliki tingkat produktiftas yang tinggi pada pekerjaan galian, sisi lain dari keunggulan metode ini adalah memiliki risiko-risiko yang dapat membahayakan keselamatan konstruksi. Risk Assessment dibutuhkan untuk memahami tingkat risiko dan mengambil langkah-langkah untuk mengurangi atau mengendalikan dampaknya. Analisa risiko yang digunakan adalah metode probabilitas dan dampak. Perspektif yang digunakan pada penilaian ini adalah berdasarkan sudut pandang kontraktor dan masyarakat, sehingga dapat dilakukan penarikan kesimpulan atau variabel yang beririsan terhadap masing-masing perspektif. Berdasarkan hasil identifikasi risiko menurut sudut pandang kontraktor terdiri dari 53 jenis risiko dan menurut sudut pandang masyarakat terdapat 12 jenis risiko. Hasil penilaian risiko menurut perspektif kontraktor menghasilkan 8 risiko berkategori tinggi dan perspektif masyarakat terdapat 3 risiko berkategori tinggi. Prioritas mitigasi risiko dilakukan terhadap risiko-risiko yang berkategori tinggi. Terdapat risiko yang beririsan terhadap pelaksanaan metode blasting antara perspektif kontraktor dan masyarakat yaitu risiko pendengaran terganggu.

Abstract

This study explores the potential use of raw rice husks as a partial substitute for sand in the production of paver blocks, addressing the increasing demand for concrete and the overuse of natural resources like aggregates. Rice husks, an abundant waste material in Indonesia, were incorporated into paver blocks made from Portland cement, sand, and raw rice husks. The initial mix ratio was 1 part cement to 8 parts sand, with subsequent mixes gradually replacing sand with rice husks in proportions ranging from 0.5 to 2 parts. The paver blocks were mixed, molded, and compacted, and their properties were tested for compressive strength, water absorption, skid resistance, and abrasion resistance. Five different mix variations were tested, and the production costs were analyzed. The findings revealed that increasing the rice husk content reduced compressive strength but improved water absorption, skid resistance, and abrasion resistance. Additionally, higher rice husk content resulted in lower production costs. The optimal mix, consisting of 1 part cement, 7.5 parts sand, and 0.5 parts rice husks, met all Indonesian standards and demonstrated the best performance. Further research is recommended to assess freeze-thaw resistance and enhance the cost-effectiveness and quality of paver production.

Abstract

Success in completing construction projects is influenced by many factors that are mutually dependent on each other, one of which is the supply chain. In 2018, the Public Works and Spatial Planning Department of West Sumatra Province, Indonesia had 24 road construction work packages. Only 33.3% were completed on time and the remaining 66.7% experienced delays, one of which was due to material delays (Rita et al., 2021). Embankment work on the Solo – Yogyakarta – YIA Kulon Progo Toll Road Project Section I Package 1.2 cannot be separated from the potential for delays. The supply chain is a special concern for this project, because the large material requirements and the difficulty of finding landfill material that meets specifications can become obstacles if the risks in each process are not managed well. The instrument used is Failure Mode and Effect Analysis (FMEA), namely by identifying failures in each process and the impacts that can occur on the activities carried out, so that mitigation actions can be determined to minimize risks that may occur. The research results showed that there are 5 supply chain activities for earth embankment work, namely raw materials, suppliers, manufacturing, distribution and consumers. There are 41 risks divided into 3 risk levels. At the raw material stage there are 4 medium risks and 2 high risks, at the supplier stage there are 7 medium risks, at the manufacturing stage there is 1 low risk and 6 medium risks, at the distribution stage there are 2 low risks and 11 medium risks, and at the consumer stage there are 8 moderate risk. There are 47 control measures which are divided into 5 aspects, namely Man, Money, Machine, Material and Method.

Abstract

Construction projects are activities that are prone to work accidents, so work safety management is needed to prevent work accidents. One of the factors that greatly influences the perception of work safety is the job security. The aim of this research is to identify job security factors and safety perceptions and analyze the influence of the relationship between job security and the perception of safety among field workers in the oil and gas industry, especially in the Riau province work area. The respondents were field workers and numbered 106 people. The research methods used are qualitative and quantitative. There were respondents who stated that the implementation of work safety was very high, but several dimensions such as sustainable salary increases were still not good (34.91%) and respondents stated that understanding and implementation of the perception of safety was very high. The results of the linear regression test show that job security has a positive and significant effect on the perception of safety among field construction workers, where job security contributes to the perception of safety by 21.5%. The more workers do not fulfill job security, the less workers will care about the perception of safety which can lead to not creating a good safety climate and increasing work accidents

Abstract

Tunneling construction is important to get more attention because considering the magnitude of the risks from this work such as the instability of the carrying capacity of the soil around the construction which can cause collapse during dredging or installation of tunneling walls, or and other problems such as lack of oxygen intake for workers who are carrying out tunneling excavations , the presence of toxic and flammable gases, or falling objects that can result in minor accidents or even death. The purpose of this study is to make a visual assessment through certain media (photos/videos) that can be done quickly regarding the existing conditions of the environment/work, whether the work carried out meets work safety standards, work safety regulations and so on. Rapid assessment can assume that what happened in the field at that time was a reflection of previous work. From the results of the study there were 58 variables which were divided into 4 main variables which were assessed based on the WBS and 26 photos of the environment of the Manikin Dam Tunneling development project taken from several sides. Calculations were made using the results of data from 6 informants, resulting in a P(H | Ecomb) value of 0.932 or a probability of 93.2%, which means that the tunnel work according to the 6 informants was carried out safely. The final value obtained from the analysis is almost close to 1 and all the results of the analysis from the 6 informants are more than 67%.

Abstract

The accident rate of building construction projects in Indonesia reached 9 cases out of a total of 48 cases (20%) from 2017 to 2022. Out of these, 43 cases were attributed to technical negligence, 4 cases were due to natural factors, and 1 case is currently under investigation. Given the issues related to construction accidents, this research aims to identify construction safety variables that are likely to occur and subsequently conduct a risk level analysis. The research methodology employed is a case study, followed by a risk analysis based on the Ministry of Public Works and Housing Regulation No. 10 of 2021 regarding the Guidelines for Construction Safety Management Systems. The research findings indicate that out of 34 construction safety risk variables, there were 2 hazards (5.88%) classified as high risk (B), 22 hazards (64.71%) classified as medium risk (S), and 10 hazards (29.41%) classified as low risk (K).
