Abstract

The effectiveness possessed by manufacturing machines is a parameter used to determine the performance of a company's manufacturing process. Effectiveness can be shown in the form of percentages as effective as a manufacturing process is carried out. Effectiveness can be a reference for companies in the implementation of production by evaluating charts of production that are considered less effective and do not meet standards. The factors that affect the effectiveness of a production machine can be seen in the availability or capability, quality, and performance where in this article the overall equipment effectiveness (OEE) method which has a production period of one month is used to get the effectiveness of the production process carried out. The results obtained in this study were 88.53% in the first week of proposition, 94.63% in the second week of production, and 91.58% in the third and last week of production.

Abstract

Thixoforming improves material properties better than conventional methods through the formation of non-dendritic or rounded structures. This study aimed to optimize the mechanical properties of Al 6061/SiC composites by adding Mg as a wetting agent through stir casting, thixoforming, and artificial aging processes. The holding time during the artificial aging process was varied to investigate its effect on microstructure, hardness, and impact toughness. SEM analysis revealed a more uniform distribution of SiC particles with increasing holding time, indicating the effective formation of Mg2Si precipitates. The maximum hardness of 48.5 HRB and the highest impact toughness of 0.022 J/mm² were obtained at the longest holding time of 3 hours. This indicates that the formation of homogeneous Mg2Si precipitates during the artificial aging process significantly contributed to the improvement of the composite's mechanical properties.

Abstract

Adanya pandemi Covid-19 yang terjadi saat ini, tidak hanya membawa masalah bagi kesehatan masyarakat, tetapi juga berimplikasi luas termasuk pada sektor pangan yang dapat mengganggu ketahanan pangan nasional, propinsi, kota/kabupaten maupun keluarga. Mitra dalam kegiatan pengabdian kepada masyarakat Skema Program Kemitraan Masyarakat (PKM) ini adalah masyarakat RT. 03 RW. 08 Kelurahan Masigit, Kecamatan Jombang, Kota Cilegon. Permasalahan mitra yaitu tinggal di pemukiman yang padat, tidak memiliki halaman yang luas dan terdapat lahan pertanian yang dikelola oleh masyarakat RT. 03 dengan cara pengolahan yang biasa, belum menggunakan teknologi yang smart. Luaran dalam kegian PKM ini adalah produk dan jasa. Jasa disini adalah berupa pemberian informasi mengenai teknologi smart farming dan tata cara budidaya hidroponik bagi masyarakat RT. 03 Jombang, Kota Cilegon melalui pelatihan. Produk yang dihasilkan dalam kegiatan ini berupa tanaman sayuran yang dipanen dengan cara hidroponik. Metode pelaksanaan yang digunakan dalam kegiatan ini adalah dengan penyuluhan yang memberikan informasi mengenai teknologi smart farming dan pelatihan budidaya hidroponik. Kegitan ini dapat meningkatkan pengetahuan masyarakat RT. 03 mengenai smart farming dan sistem kerjanya dan juga dapat melakukan budidaya tanaman dengan hidroponik sehingga ketahanan pangan keluarga di dapat terjaga, dengan terjaganya pangan keluarga dapat menjaga kesehatan anggota keluarganya .

Abstract

Roof tiles play a vital role in the construction industry hagoslot by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

This study investigates the dugemslot mechanical properties of a Pajajaran-era golok to reveal the traditional metallurgical technology and cultural values embedded within it. The main issue addressed is the absence of scientific data regarding the manufacturing process and mechanical properties of ancient golok, thus this research aims to identify both aspects. The methodology involved Vickers hardness testing and metallographic analysis using an optical microscope, preceded by geometric measurements and specimen preparation through grinding, polishing, etching. The results indicate a graded mechanical property along the blade, with an average hardness of 184.01 HV: 150.13 HV at the upper section, 189.5 HV at the middle, and 212.4 HV at the lower section. Microstructural observations revealed a dominance of ferrite in the upper section, a combination of ferrite and pearlite in the middle, and a dense pearlite structure in the lower section. These findings suggest that the golok was manufactured using a casting technique combined with differential heat treatment, producing graded mechanical properties: ductile at the spine, balanced at the middle, and hard at the cutting edge. This research contributes to a deeper understanding of traditional metallurgical technology in Nusantara and serves as a reference for further studies as well as cultural preservation through scientific approaches.
