The wheel bolt of the CN235 220M aircraft is a type fastener crucial for maintaining air pressure within tire. It was discovered that this component fractured during operation. This study aims to conduct forensic analysis on mechanism and causes material failure through micro macro morphological observations, chemical composition tests, microstructural analysis, hardness testing bolt. Micro-morphology results showed crack tip in initiation zone, which became stress concentration point....
On the Ende-Kelimutu national road section at STA 8+425, according to identification and field survey, landslide that occurred this point was caused by high rainfall intensity geological factors of slope. As supervisor, Balai Pelaksanaan Jalan Nasional (BPJN) East Nusa Tenggara has designed a treatment using combination cantilever walls drilled poles. Soil investigation data 8+425 shows slope is dominated sand with N-SPT values above 15 depth 14.45 meters. When making design improvements,...
The National Road Construction Agency (BPJN) in East Nusa Tenggara Province through the Satuan Kerja IV (Satker) has repaired some landslide points Ende – Wolowaru and Junction Kelimutu Preservation working package. One of that need treatment is at STA. 10+475. Based on survey planning results from Satker P2JN BPJN NTT, most dominant factors trigger landslides are geological conditions high rainfall. Data soil investigations location STA 10+475 after occurred showed was dominated by sandy...
The development of IKN Nusantara (Indonesia's New Capital City) in phase I, 2022-2024, focuses on basic infrastructure development, one which is the Toll Road Segment 3A Karangjoang - KKT Kariangau (STA 14+000 STA 25+909) Balikpapan. This will add back to Indonesia's assets, especially Ministry Public Works and Housing. One main works construction this toll road excavation embankment work, need for a lot material problem itself so that excavated soil as much possible sought be used by mixing...
The Pasuruan-Probolinggo Section 4 Toll Road project which has a length of 12.04 km is dominated by silty clay - clay. In addition to soft soil, there are other problems in the construction Pasuruan Probolinggo toll road, namely limited availability embankment soil material around site and location quarry quite far away. addition, when relying on from quarry, weather factor will play very important role rainy then activity stops, targeted volume not met progress work that day achieved....
Abstract In the region there was generally influenced by seasonal weather such as highly rainfall intensity, slope failure will be existence of water and these conditions may trigger changing surface on slope. The increasing pore pressure causes shear strength reduction stength enhancement. Consequently, level changes need to evaluated conscientiously. this paper, various levels are applied perform different below ground surface. Many methods commonly used predict stability mechanism,...
Settlement of embankments on soft soils is a significant problem in geotechnical engineering to maintain pavements, buildings, and other facilities them.The that often arises not being able predict the magnitude consolidation compression accurately, this occurs due uncertainty field conditions, laboratory testing, data interpretation, as well assumptions made development 1-D theory.Based causes inaccurate settlements predictions, it necessary carry out research better method for predicting...
There are many methods for calculating the bearing capacity of a pile foundation. The problem is finding most representative method analysis dynamic load testing (PDA) results in field. This study only covers areas West Surabaya and North Surabaya. used to analyse foundation this empirical method, namely Schmertmann, Meyerhof, L. Decourt finite element (FEM.). research precast foundations. initial stage was collect soil survey data form N-SPT boring logs PDA test area. Then calculation...
Apartemen Tamansari Emerald berada di jalan Mansion TX 3 Citraland, Surabaya dan terdiri atas 41 lantai 1 basement. Pondasinya menggunakan raft foundation dengan pondasi tiang tipe spun pile berdiamter 60 cm. Adapula dinding penahan tanah pada basement ditanam sedalam 3,55 meter tebal 25 Jenis apartemen ini dominan lempung yang memiliki potensi kembang susut muka air tanahnya -0,5 dari tanah. Demi mendapatkan perencanaan terbaik, dilakukan evaluasi eksisting alternatif untuk Berdasarkan...
TPA Melonguane merupakan satu-satunya yang beroperasi di Kabupaten Kepulauan Talaud, tepatnya terletak Pulau Karakelang. Lokasi dari tersebut daerah perbukitan dengan kontur bervariasi antara +70,00 hingga +86,00 dikelilingi lahan terbuka. Pada awal tahun 2019, mengalami kerusakan karena adanya bencana alam berupa tanah longsor. Kelongsoran terjadi jalan difungsikan sebagai menuju IPL. Lalu, pada bulan Agustus 2019 longsor susulan lereng dekat bangunan workshop IPLT. Oleh itu, perlu...
Reclamation fill requires material to fulfil the particle gradation requirements as follow : gravel 30% max, sand 50% min, and silt-clay 20% max. Generally, field officer wants know density degree of when it has arrived in immediately easily by using sieve testing. Water content changing caused rainy season tidal, taking largest part affecting strength soil. This laboratory test research is taken from quarry river, shores hills which have requirement follows: 80% represented sand. tested...
Jakarta merupakan Ibukota Indonesia. terletak di pantai utara Pulau Jawa. Berada pada perairan laut Jawa menyebabkan Teluk menjadi tempat bermuaranya sungai-sungai yang membelah kota Jakarta. Wilayah mengalami penurunan tanah antara 10 cm sampai 180 cm, tergantung letak wilayahnya, sehingga mengancam kawasan tergenang secara permanen. Salah satu solusi untuk menangani ancaman tergenangnya adalah akan dibuat tanggul laut. Sehingga dilakukan penyelidikan disepanjang dimana susunan dan...
Salah satu pengembangan yang dilakukan oleh PT. Perusahaan Listrik Negara (PLN) di Sorong adalah perluasan lahan PLTMG (Pembangkit Tenaga Mesin Gas) sebagai usaha peningkatan kapasitas listrik menjadi 50 MW. Perluasan ini direncanakan seluas 4,6945 hm2 dan untuk pembangunan sebuah tangki tegak berisi light fuel oil (LFO) Sumber energi pembangkit listrik. Disamping itu, terdapat beberapa kondisi dapat menghambat perencanaan seperti lapisan tanah eksisting didominasi lanau kelempungan, daya...
