Abstract

The development of production techniques is required to produce good products that have standards for the products produced, both in terms of profile shape, size precision, surface roughness, hardness, material flexibility, and others that comply with standards. The surface roughness of a product can affect its functions, such as its level of precision and ability to accept loads. This research aims to find out how much influence cutting speed and depth of cut have on surface roughness with variations in cutting speed parameters of 21 meters/minute and 26 meters/minute and for AISI 4140 steel cutting speed parameters of 12 meters/minute and 17 meters/minute and cutting depths of 0.1 mm and 0.3 mm on four types of steel with End Mill cutting blades made from High-Speed Steel with a total of 4 flute cutting blades. Next, surface roughness testing and analysis of variance were carried out to determine the influence of parameters on surface roughness. The results obtained were that the largest average surface roughness, namely Ra = 5.33 µm, occurred on AISI 4140 steel at a cutting speed of 12 m/min with a cutting depth of 0.3 mm. Meanwhile, the smallest average surface roughness, namely Ra = 0.91 µm, occurred on AISI 1045 steel at a cutting speed of 21 m/min with a cutting depth of 0.1 mm. Next, an analysis of the variance method was also carried out with the following results: cutting speed only affected S45C steel because the value of Fcount>Ftable (13.18107506 > 5.32). The depth of cut does not have a significant effect on surface roughness on all types of steel because of the comparison results Fcount<Ftable. The interaction of cutting speed and cutting depth does not affect surface roughness because the comparison shows that Fcount <Ftable for all types of steel.

Abstract

The field of materials and technology has developed rapidly, various types of inventions have been developed and researched to obtain new materials that are suitable for use at low production costs. The potential of bamboo plants is promising where the availability is abundant and sustainable, the utilization of specimens is made with polyester binders reinforced with natural and synthetic fibers. The type of bamboo that will be investigated for the tensile strength and toughness of the specimen with the difference in fiber volume fraction is a reference for the combination of bamboo fiber and fiber-glass where the volume fraction of 25% SB:25% FG, 35% SB:15% FG and 40% SB:10% FG particles at a fixed resin volume is 50%. Of the three variations in the volume fraction, the highest tensile strength in a balanced fiber filler is 40% bamboo fiber: 10% fiber-glass with an average value of 80.907 MPa, with a tensile strain of 2.53 % The lowest tensile strength value is in the volume fraction of 35% bamboo fiber: 15% fiber-glass with an average value of 75.552 MPa, with a tensile strain of 2.09%. For the highest toughness value of the specimen is in the volume fraction of 35% bamboo fiber: 15% fiber-glass, i.e., 0.83 J〖/mm〗^2 With an absorbed energy of 43.73 joules. On the other hand, the lowest toughness value is in the volume fraction of 25% bamboo fiber: 25% fiber-glass with an average value of 0.24 J〖/mm〗^2. With an absorbed energy of 39.94 joules. The observation results showed that the fiber volume was good at a percentage of 40% SB with 15% FG suitable for combination as an alternative tensile material. The toughness value in the volume fraction of 40% SB:10% FG is very low. However, the observation of bamboo fiber fracture results has a strong enough ability for the application of manufacturing products and others.

Abstract

As the era progresses, conventional fuel becomes more expensive This causes people to experience fuel difficulties daily cooking needs due to economic shortages. hence the used oil and used cooking oil is an alternative energy. but oil is needed special treatment so that it can be used as fuel. make an alternative stove fueled by economical used oil could be the solution. Method Experimental is a quantitative method used to determine variables independent (treatment) to the influence of the dependent variable (outcome) in the condition which is under control. The research uses three variables, namely the independent variable, fixed variable and dependent variable. which is where testing is carried out with water boiling test method. The fastest start-up time data is obtained by the material Burn used cooking oil in 5 minutes and take the longest to get oil used with a time of 6 minutes. shortest boiling time obtained used cooking oil, namely 5.28 minutes. and for thermal data efficiency for each material burn ranges from 14% to 26%. fuel consumption ranges from 0.526kg to 0.615kg. The boiling point of water is 99.93℃. From the variations of the three fuels used in testing, namely used oil, used cooking oil, and used oil with mixture of used cooking oil, used cooking oil is a type of fuel the most optimal with a thermal efficiency value of 26%, fuel consumption 0.615 kg/hour. better match the blower speed to the nozzle hole.

Abstract

In the development of materials science, especially polymers, natural fibers such as areca nut shell fiber are increasingly attractive to use. The use of synthetic polymer materials made from fiber can replace conventional materials such as metal, wood and leather. They can replace conventional materials with the advantages of lower price, environmental friendliness, and recyclability. Areca nut shell fiber, as an example of a natural fiber, has great potential in the furniture industry, crafts, and as an ingredient in traditional medicine. This fiber is used as a reinforcing material in composites with an Unsaturated Polyester Yukalac resin matrix. Unsaturated Polyester Yukalac resin, with characteristics such as stiffness, flexibility, water resistance, chemical resistance and weather resistance, is used as a matrix in making composites. The aim of this research is to make a plastic composite prototype reinforced with areca palm fiber, varying the volume fraction of areca nut shell fiber by 30%:50%, 50%:60%, 70%:70%, 90%:80% and for the matrix using polyester resin. BQTN 157 EX. The fiber composition is arranged in a mold in the same direction using the hand lay up method. Composite testing is in the form of a tensile test referring to the ASTM 638-03 standard. The results of the largest tensile testing process were with a volume fraction of 50% with an average value of 7.11 MPa, and for tensile testing the lowest was a volume fraction of 70% with an average value of 6.17 MPa, it can be concluded for reinforced plastic composites Areca nut shell fiber has considerable ability to be applied as a structural material. This is a step towards the development of innovative and environmentally friendly composite materials for various industrial applications.

Abstract

Peningkatan jumlah kendaraan bermotor di Indonesia, terutama mobil, telah mendorong kebutuhan akan bengkel perawatan kendaraan. Namun, lingkungan kerja di bengkel mobil memiliki potensi risiko tinggi terhadap kecelakaan dan kesehatan pekerja. Sosialisasi Keselamatan dan Kesehatan Kerja (K3) bertujuan untuk melindungi karyawan bengkel dengan meningkatkan kesadaran tentang bahaya potensial dan langkah-langkah pencegahan. Melalui sosialisasi K3, budaya keselamatan dan kesehatan dapat dikembangkan di bengkel, menciptakan lingkungan kerja yang lebih aman dan sehat. Sosialisasi ini juga memberikan kesempatan untuk meningkatkan pengetahuan karyawan tentang risiko potensial dan cara menerapkan K3, yang dapat mengurangi biaya perawatan dan pemeliharaan mesin. Kegiatan ini diharapkan akan menciptakan lingkungan kerja yang lebih produktif dan berkelanjutan di bengkel kendaraan. Dari hasil sosialisasi K3 di Miing Bengkel dapat dilihat bahwa terjadi peningkatan yang cukup signifikan terhadap pemahaman peserta sosialisasi. Sehingga dapat disimpulkan bahwa kegiatan sosialisasi ini memiliki dampak yang sangat besar untuk meningkatkan pemahaman peserta dalam penerapan K3 di lingkungan bengkel. Jika peserta memiliki tingkat pemahaman yang baik/tinggi terhadap pentingnya penerapan K3 saat bekerja, maka dapat meminimalisir terciptanya kondisi tidak aman saat bekerja sehingga dapat menurunkan angka kecelakaan kerja di lingkungan bengkel. Oleh karena itu, kegiatan sosialisasi ini direncanakan akan terus dilakukan dan dikembangkan, agar cakupan peserta semakin banyak.  Sehingga akan membantu masyarakat untuk meningkatkan standar keselamatan dan Kesehatan kerja dalam berkegiatan sehari-hari.
