Abstract

Kelongsoran pada umumnya disebabkan karena rendahnya kuat geser tanah pembentuk lereng, peningkatan beban luar atau kondisi hidrolis dan tingginya kadar air. Kerusakan yang ditimbulkan tidak hanya berdampak langsung seperti rusaknya fasilitas umum, lahan pertanian ataupun korban jiwa akan tetapi juga menimbulkan dampak tidak langsung seperti menghambat kegiatan pembangunan dan aktifitas ekonomi pada daerah yang terkena bencana. Tujuan dari penelitian ini adalah untuk menghitung dimensi dinding penahan tanah gravity dengan jenis tanah pasir sehingga syarat faktor keamanan terhadap guling, geser, dan daya dukung tanah terpenuhi. Dimensi dinding penahan tanah yang diperoleh dalam penelitian ini adalah, tinggi dinding penahan tanah H = 6 m, lebar tapak B = 5,5 m, hell 2,5 m dan toe 0.5 m. Dari hasil perhitungan diperoleh nilai faktor keamanan terhadap stabilitas guling = 5,25, stabilitas geser = 1,57, dan stabilitas daya dukung tanah = 5,11.

Abstract

Occupational Safety and Health (K3) is a form of effort to create a workplace that is safe, healthy, free from environmental pollution, so that it can protect and be free from work accidents, ultimately increasing work efficiency and productivity. Schools are responsible for keeping the environment clean, beautiful and orderly so that a conducive learning environment can be created. Therefore, schools are also required to have professional staff who understand and are competent in the field of K3. The aim of this service is to provide knowledge to high school students in South Solok Regency so that they care more about K3 in their respective school environments. This service found that there was still low awareness of K3 among teachers and high school students in South Solok Regency, it was recorded that the cleanliness of toilets and bathrooms was very lacking in each school, school cleanliness was very lacking, awareness of the use of PPE when driving two-wheeled students was very lacking. especially wearing a helmet. There is a need for guidance in schools, especially for these students, especially regarding K3 culture in schools.

Abstract

Dinding penahan tanah (DPT) dibangun untuk mengatasi kelongsoran. Salah satu konstruksi DPT yang sering dipakai adalah DPT segmental atau Segmental Retaining Wall (SRW) yang terdiri dari 2 tipe yaitu SRW gravity dan SRW reinforced. SRW gravity merupakan DPT yang mengandalkan berat sendiri strukturnya. SRW reinforced memakai geosintetik untuk perkuatan terhadap kestabilan dindingnya. Selama ini, analisis kestabilan SRW gravity selalu dianggap seperti DPT monolit. Selain metode analisis yang dianggap sama, pola kelongsoran tanah yang terjadi di belakang SRW juga dianggap sama, sehingga sudut kelongsoran tanah (a) uji laboratorium yang terjadi sama dengan sudut kelongsoran metoda Rankine (q=45o+f/2). Penelitian skala laboratorium dilakukan dengan beberapa skenario balok-balok SRW serta pemberian tanah pasir dan pembebanan merata (statis) di belakang SRW. Pola kelongsoran tiap skenario SRW direkam untuk mengamati sudut kelongsoran. Pola kelongsoran yang terjadi membentuk kurva S dengan persamaan fungsi polinomial pangkat tiga. Berdasarkan pengamatan terhadap beberapa skenario SRW, terlihat bahwa besar sudut kelongsoran (a) yang terjadi di dasar kurva kelongsoran sama dengan sudut geser dalam tanah pasir (f) tersebut.

Abstract

This study aims to determine the right type of foundation in the construction of higher education buildings, with a focus on the planning of raft foundations. This study includes the calculation of soil bearing capacity, planning of foundation dimensions and reinforcement, analysis of settlement and uplift, and cost estimation. The methodology used follows the SNI standard, HSP Quarter II of Padang City, and uses ETABS software. Analysis of soil bearing capacity is carried out based on the Meyerhof method using Microsoft Excel, while the loading is analyzed through ETABS. The results of the study indicate that the raft foundation planned for Building C of Dharma Andalas University is able to withstand existing soil tension of 9.755 t/m², which is below the permitted bearing capacity of 39.169 t/m². This foundation is designed with a thickness of 450 mm, using D13 mm threaded reinforcement with a distance of 200 mm and 250 mm. The planned sloof dimensions are 40 cm x 80 cm with 20D22 mm main reinforcement and D10 mm stirrups. The settlement analysis shows a value of 46.997 mm, which still meets the permit limit of 100 mm. The estimated total cost of building a raft foundation, including 11% VAT, is Rp1,673,300,000.00. Based on these results, the planned raft foundation is declared capable of withstanding the load on existing soil conditions and meets the permit stress requirements. This study recommends further exploration of the application of raft foundations on different types of soil and the development of alternative designs for simpler construction.

Abstract

Brick is one of the materials used for construction. One of the brick-producing areas in West Sumatra Province is Padang Pariaman Regency. This study was conducted to determine the quality of bricks, both in terms of shape, strength and forming materials. The tests carried out were shape and size tests, compressive strength tests. The tests were carried out at the Padang Institute of Technology Materials Laboratory by randomly taking brick samples from manufacturing furnaces in 3 (three) Districts in Padang Pariaman Regency. From the test results, recommendations will be made for good quality bricks for construction work and if low quality bricks are found, recommendations will be given for improvements to the brick-making furnaces. The results showed that the size of the test bricks from 3 (three) Districts in Padang Pariaman Regency did not meet the standard size of SNI 15-2094-2000. The average size is 101.34 mm in length, 92.59 mm in width and 49.98 mm in height. The results of the brick compressive strength test were 2.66 N/mm2, which does not meet the SNI 15-2094-2000 standard of at least 5 N/mm2.
