Abstract

The larger the local area, the more naturally wood is available as a construction material. Compared to other basic materials, wood is a lightweight material suitable for use with simple hardware. Wood can be used in construction. Flexural strength is a type of shaft that requires considerable consideration. The purpose of this study is to determine specifically the real properties, mechanical properties, and flexural strength of plywood (glulam), in meranti wood and wadang wood, which comes from the Malang Regime. Explicit gravity testing, flexural strength, and moisture content were all conducted. Glulam radiation was tested using Epoxy and Crona sticks. The analysis results show that meranti wood and wadang wood have typical air contents of 18% and 19% respectively and typical thicknesses of 0.69 (Ton/m3) and 0.37 (Ton/m3) respectively. Based on laboratory results, the typical thick flexural strength of meranti and wadang timber perfect beams is 61.72 MPa and 38.96 MPa. In meranti wood and wadang wood, the covering layer made with paste and glue with pegs usually has a flexural strength of 22.16 MPa and 24.16 MPa, respectively.

Abstract

Sand and crushed stone from the Babulu River in Malacca Regency is one of the materials that is often used by the local community as an aggregate for concrete construction, as a construction material the aggregate must meet technical requirements. The research method used was experimental with cylindrical samples measuring 15 cm x 30 cm and beams measuring 8 cm x 12 cm x 120 cm. The aggregate variations used were 0%, 25%, 50%, 75%, and 100%. Data were analyzed by assessing physical properties such as sieve analysis, silt content, moisture content, and specific gravity of aggregates. Further testing was carried out to test the compressive strength of concrete, to test the bending strength of the beam, and the deflection that occurs in the beam. The results showed that the sand and crushed stone material from Babulu River had a fineness modulus of 3.61%, while that of Malang Regency was 2.63%. Meanwhile, for coarse aggregate, the fineness modulus gradation of Babulu River is 4.06%, while that of Malang Regency is 4.43%. The use of the 50% variation of aggregate material from the Babulu River in the concrete mix produced a fairly good average compressive strength value. At 28 days of age, concrete using material from the Babulu River achieved an average compressive strength of 16.26 MPa. Reinforced concrete beams using materials from the Babulu River had an average flexural load-bearing capacity of 1,800 kg and an average deflection of 5.16 mm.

Abstract

Micro, small, and medium enterprises (MSMEs) "Lancar Jaya" Bricks in Turen District, Malang Regency, East Java produce bricks. In the results of the situation analysis, it was found that the most urgent problem was the production capacity of SMEs which could not be optimal in producing bricks because they only had one kneading tool, which was used interchangeably with several other groups of workers, so that the time used for production was not very effective. In addition, it has narrow land, so the drying process is also limited for production. Market demand began to decline. To increase the production of bricks, the solution offered in the production field is to make the primary production tool more effective and efficient and to make a firm mixture of bricks. In business management, the solution offered is to increase the human resource capacity of business actors through training and mentoring. Outcome targets include appropriate technological tools in the form of modifications to serial brick mixing tools, activity videos, national journals with ISSN, e-proceedings, and mass media. The results of this program are the effectiveness of the three series red brick mixer machine by 75%, an increase in production capacity of 200%, and an increase in income turnover of 30%. The increase in marketing area from 1 city to 3 city areas and the quality of red bricks produce good products that are not easily broken, only 90% of the products produced.\ABSTRAKUsaha mikro kecil menengah (UMKM) Batu Bata “Lancar Jaya” di Kecamatan Turen Kabupaten Malang Jawa Timur memproduksi batu bata. Pada hasil analisis situasi ditemukan bahwa masalah yang paling urgen adalah kemampuan produksi UMKM yang tidak bisa optimal dalam memproduksi hasil batu bata karena hanya memiliki 1 buah alat adonan yang digunakan bergantian dengan beberapa kelompok pekerja lainnya sehingga waktu yang dipergunakan untuk memproduki sangat tidak  efektif. Selain itu memiliki lahan yang sempit sehingga proses penjemurannya juga terbatas untuk produksi. Permintaan pasar mulai menurun. Untuk meningkatkan produksi batu batanya, solusi yang ditawarkan di bidang produksi adalah membuat alat utama produksi yang lebih efektif dan efisien serta membuat komposisi campuran adonan batu bata yang kuat. Di bidang manajemen usaha, solusi yang ditawarkan adalah peningkatan kemampuan SDM pelaku usaha melalui pelatihan dan pendampingan. Target-target luaran yang disusun antara lain adalah alat teknologi tepat guna berupa modifikasi alat adonan batu bata berseri, video kegiatan, jurnal nasional ber-ISSN, e-prosiding dan media massa. Hasil dari program ini adalah efektivitas mesin mixer bahan batu bata merah 3 series sebesar 75%, peningkatan kapasitas produksi 200%, omzet penghasilan meningkat 30%. Peningkatan luas pemasaran dari 1 wilayah kota menjadi 3 wilayah kota dan kualitas batu bata merah menghasilkan produk yang bagus tidak mudah pecah hanya 90% dari produk yang dihasilkan.

Abstract

Construction companies must focus on occupational health and safety (K3) and must cover the safety and welfare of workers. JKK (Work Safety Committee) has carried out various safety assessments and risk assessments to improve worker safety and health. Comfortable Housing Boarding House PT. has carried out a risk assessment using the Prima Land method to assess the risk and safety of construction projects. The study found 13.3% of risks were classified as extreme, 30% high risk, 13.3% moderate risk, and 43.34% low risk. Risk assessment methods will be used in this research to further improve K3 working conditions and ensure worker safety. This study identified three main factors that influence OHS health and safety: organizational culture, environment, and risk assessment methods. By implementing these measures, construction companies can improve their OSH safety and health management section and reduce the risk of accidents and injuries.
