Abstract

In the turning process, the surface finish of a workpiece can influence the level of visual quality of a workpiece. CNC machine cutting parameters include feed speed, feed depth, and cutting speed. The aim of this research is to determine the effect of carbide insert tool types ZCC WNMG 060408 – DM and VBMT 160408 – HM on the average roughness value in the turning process with a rotational speed of 500 rpm and feed speed variations of 0.10 mm/rev, 0.15 mm/ rev and 0.20 mm/rev on S45C steel material. This research is located at PT. Bin Smeer Jaya with the research sample, namely S45C steel material. This research will be carried out with 3 samples of surface roughness testing each with varying feeding, where the turning process will be carried out on a CNC lathe machine first using ZCC WNMG 060408 – DM and VBMT 160408 – HM carbide insert chisels. The desired roughness standard is 1.8 µm – 2.2 µm. Based on the results of testing the surface roughness value of S45C steel material, the data obtained using the Handysurf E-35 surface roughness measurement tool, the roughness value using the ZCC WNMG 060408 – DM specimen 3 feeding 0.20 mm/rev carbide insert chisel was 2.38 µm, whereas for specimen 3 feeding 0.10 mm/rev is 4.11 µm. Then for the VBMT 160408 – HM carbide insert chisel, specimen 1 feeding 0.10 mm/rev is 1.48 µm, while for specimen 2 feeding 0.20 mm/rev it is 4.41 µm. So it can be concluded that the lowest roughness value occurs in the VBMT 160408 – HM carbide insert chisel compared to the ZCC WNMG 060408 – DM carbide insert chisel type. Therefore, the best level of surface roughness results occurs in the VBMT 160408 – HM carbide insert with the desired roughness standard and optimal visual quality

Abstract

The engine pump is used to move fluids by converting mechanical energy into fluid energy and pressure, then transporting the fluid through the piping system. The use of pumps to meet clean water needs. The method with the working principle or how the pump flows fluids or provides fluid power, the results of the study show that the pump capacity with a water discharge of 15 L / m, the total head is 4.807 m, and after knowing the curve where there is an increase in pressure at the outlet (discharge pressure) there will be a decrease in the amount of flow and the higher the amount of flow that comes out, the higher the pressure capacity of the fluid. In the demin water transfer pump, it is known that the available NPSH (6.7 meters) is greater than the required NPSH (6.2 meters), so the pump can. So to fill the water reservoir at the Permanent Nursery Service, the pump operates for 8.5 hours per day. Data analysis and discussion can be concluded that the pump capacity with a water discharge of 15 L/m, the total head is 4.807 m, In the demin water transfer pump it is known that the available NPSH (6.7 meters) is greater than the required NPSH (6.2 meters), so the pump can work without experiencing cavitation. So to meet the needs of the water reservoir in the Permanent Nursery Division, the pump operates for 8-5 hours per day.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesadaran masyarakat terhadap pentingnya kebersihan lingkungan pesisir melalui aksi bersih pantai di Pantai Dusit Kota Balikpapan. Metode pelaksanaan dilakukan melalui partisipasi aktif dosen dan mahasiswa Program Studi Teknik Mesin Universitas Balikpapan dengan pendekatan aksi langsung dan edukatif. Hasil kegiatan menunjukkan terjadinya pengurangan sampah pesisir, meningkatnya kepedulian lingkungan peserta, serta terbangunnya kesadaran kolektif masyarakat sekitar. Kegiatan ini diharapkan dapat menjadi model pengabdian berkelanjutan dalam pelestarian lingkungan pesisir.

Abstract

Penelitian ini menganalisis pengaruh kecepatan potong, kecepatan pemakanan, dan kedalaman potong terhadap kekasaran permukaan hasil pembubutan baja karbon ST42. Pengujian dilakukan menggunakan mesin bubut konvensional dengan spesimen ST42 berdiameter 30 mm dan panjang 50 mm. Parameter permesinan divariasikan pada kecepatan potong 100–500 rpm, kecepatan pemakanan 2,25–2,50 mm/rev, serta kedalaman potong 1,5 mm dan 2,5 mm. Pengukuran kekasaran permukaan dilakukan menggunakan surface roughness tester Mitutoyo SJ-310. Hasil penelitian menunjukkan bahwa peningkatan kecepatan potong menurunkan kekasaran permukaan, sedangkan peningkatan kecepatan pemakanan meningkatkan kekasaran. Nilai kekasaran permukaan terendah sebesar 3.792 µm diperoleh pada kecepatan potong 500 rpm, kecepatan pemakanan 2,25 mm/rev, dan kedalaman potong 2,5 mm

Abstract

Masalah korosi merupakan suatu material yang prosesnya berjalan lambat. Berbagai faktor dapat mempengaruhi terjadinya korosi diantaranya lingkungan campuran logam dan lain-lain. Aluminium mudah dibentuk, bisa ditempa menjadi lembaran, ditarik menjadi kabel, dan diekstrusi menjadi batang dengan berbagai bentuk penampang. Inhibitor secara umum adalah zat kimia. Penggunaan tiga jenis larutan yang berbeda memberikan pengaruh yang signifikan terhadap laju korosi pada permukaan plat aluminium 1100-0. Larutan HCl menunjukkan tingkat korosivitas paling tinggi karena sifatnya sebagai asam kuat yang mampu melarutkan lapisan oksida pelindung aluminium, sehingga mempercepat terjadinya reaksi elektrokimia dan meningkatkan laju korosi secara signifikan. Penggunaan inhibitor berupa cat epoxy diperlukan sebagai pelindung permukaan aluminium 1100-O karena material ini rentan mengalami korosi ketika terpapar langsung oleh larutan yang bersifat asam, oksidatif, maupun basa. Cat epoxy berfungsi sebagai lapisan penghalang yang efektif untuk mencegah kontak langsung antara permukaan aluminium dan lingkungan korosif.
