Roof truss of lightweight steel has been used for any types of construction. Functioned as the truss, this could makes variations of roof truss configuration which depended on construction necessity and performance on certain span. Then, this research analyzed the configurations for short span and intermediate span. The result will recommend roof truss configuration which used light weight steel. The analysis used software SAP 2000 v.19. The lightweight steel section is channel section of C 75.35.0,75 which is found on any store building. In general, the result of this analysis were tensile and compressive ratio which is obtained by comparison of internal force and section capacity. This calculation also referred to SNI 7971:2013 code. Then, tensile and compression ratio are obtained less than 0,9 for each configurations and spans. So, the structure are stable. However, Fink and Cremona configuration have considerable results which give the smallest tensile and compression ratio compared to another configurations for short span and intermediate span respectively. It can be concluded that Fink and Cremona were recommended for lightweight steel truss for short spans and intermediate spans. Lightweight steel section C 75.35.0,75 also can be used in this configuration.

Penelitian tentang baja ringan sudah sangat meningkat untuk menentukan analisis dan desain yang tepat. Salah satu peraturan di Indonesia tentang desain struktur baja canai dingin atau ringan adalah SNI 7971: 2013. Namun, ada hal yang menjadi fokus perhatian pada baja ringan saat didesain pada elemen tekan. Salah satu tekuk yang terjadi pada elemen tekan baja ringan yaitu tekuk lokal yang disebabkan oleh faktor geometri atau penampang. Setiap penampang baja ringan memberikan bentuk tekuk yang berbeda-beda. Untuk itu perlu dilakukan studi eksperimental tentang perilaku tekan pada beberapa bentuk profil baja ringan kanal C baik tunggal dan simetris ganda, seperti double channel box dan double channel back to back. Uji tekan akan dilakukan dengan universal testing machine dengan jumlah benda uji sebanyak 3 sampel, 1 sampel untuk masing-masing penampang, sebagai kolom pendek. Hasil pengujian ini adalah berupa kurva beban versus perpendekan yang akan dibandingkan dengan hasil analitik berdasarkan peraturan SNI 7971:2013. Selain itu, propagasi tekuk lokal yang terjadi di masing-masing penampang juga diamati. Berdasarkan hasil pengujian tersebut didapatkan penampang double channel box memiliki nilai beban ultimit dan kekakuan yang signifikan dibandingkan double channel back to back dan single channel. Selanjutnya, perhitungan kapasitas tekan berdasarkan SNI 7971:2013 sangat konservatif.

Perkembangan teknologi bahan konstruksi saat ini menunjukkan kecenderungan penggunaanmaterial yang semakin efisien sesuai dengan kebutuhan. Salah satunya adalah penggunaanmaterial baja ringan sebagai elemen struktur dalam konstruksi bangunan. Dalam perakitanelemen struktur menjadi satu kesatuan, sistem sambungan pada konstruksi baja ringanmempunyai peranan yang sangat penting. Paper ini membahas hasil studi eksperimentalsambungan pada elemen struktur baja ringan dengan menggunakan alat sambung sekrup. Profilbaja ringan yang digunakan dalam penelitian ini adalah profil berbentuk kanal dengan ukuran75 x 35 mm dengan ketebalan 0,75 mm. Karakteristik material diperoleh melalui uji tarikdengan mengacu kepada Annual Book of ASTM Standars 1991 Section 3. Perilaku sambungandiamati untuk 4 spesimen benda uji yang disambung pada kedua bagian sayap penampangkanal dengan konfigurasi sambungan sejajar satu baris. Dengan menggunakan UniversalTesting Machine, beban aksial tarik diberikan secara bertahap kepada spesimen sampai tercapaikondisi ultimate. Dari hasil pengujian terlihat bahwa kegagalan sambungan disebabkan olehterjadinya kerusakan pada lubang sambungan sehingga alat sambung sekrup berotasi padabidang gaya tarik. Pola kegagalan sambungan ini merujuk pada salah satu jenis kegagalan‘tilting’ yang didefinisikan oleh Peraturan Baja Ringan AS/NZS 4600:2005 dan SNI BajaCanai Dingin 2013. Nilai beban ultimate yang diperoleh dari hasil eksperimental menunjukkankesesuaian dengan formula analitik yang ada pada peraturan baja ringan dengan rata-rataperbedaan hasil sebesar 7,8 %.Kata kunci: baja ringan, beban ultimate, sambungan, sekrup

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.

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.

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.
