Abstract

The study focuses on producing cushioning packaging material from bamboo fibers. The effects of varying the surface treatment duration and the proportions of foaming agents, adhesives, plasticizers, cross-linking agents, and other components were analyzed in terms of foam density, foaming rate, elasticity, and bubble size. The optimal reagents and the ideal ratios for the different components were identified. The parameters for the foaming process were determined based on a high-efficiency, eco-friendly foaming mechanism. Impact testing was conducted to obtain curves for maximum acceleration versus static stress, dynamic stress versus strain, and dynamic buffering factor versus stress. The study examined the dynamic buffering performance as a function of drop height and compared it to other cushioning materials. The findings indicate that at a height of 450 mm, the bamboo pulp product exhibited a lower peak acceleration value than EPE and EPS in the stress range of 2.8-5.4 kPa, indicating superior cushioning performance under these conditions.

Abstract

The rice milling industry has a strategic role in ensuring the availability of high quality rice for the community. However, the milling process often faces challenges, such as less than optimal separation of rice husks and high dust production which can have a negative impact on rice quality and worker health. To overcome this problem, this research reviews the use of cold plasma technology in rice grinding machines to increase the efficiency of separating rice husks while reducing the amount of dust produced. The results of the review show that the application of cold plasma technology can increase the efficiency of separating rice bran by reducing its adhesive force to rice grains, thereby producing better quality rice. Apart from that, this technology also contributes to reducing dust production, increasing energy efficiency and reducing operational costs. Even though it has various advantages, the implementation of this technology still faces challenges, such as high initial investment costs and the need for further research regarding its long-term impact on rice quality. With continued development and innovation, cold plasma technology has the potential to become an effective and sustainable solution in the modernization of the rice milling industry.

Abstract

This review discusses the performance and efficiency of water pumps equipped with automatic sensors to increase operational efficiency in various industrial and household sectors. Water pumps play an important role in water distribution systems, but the main challenges that often arise are high energy consumption and performance problems. This research explores the integration of automated sensors that can monitor and regulate pump performance in real time, enabling adjustments according to dynamic operational conditions. By using sensors to measure important parameters such as pressure, flow and temperature, this system can increase energy efficiency and prevent pump damage in the first place. Research findings show that use of this technology can provide significant energy savings, extend pump life, and improve overall system efficiency. This research provides practical solutions for industry in optimizing water pumping systems more efficiently and environmentally friendly.

Abstract

This research focuses on the design of fixture aids to support the manufacturing process of Circular Pattern Interpolation Products (CPIP), such as disk brake components, flanges, turbine disk runners, and other plate components with circular feeding patterns in the 3-Axis CNC machining process. The objective of this study is to achieve more efficient CPIP production times on 3-Axis CNC machines. The research methodology employed a design and build approach, involving the design of fixture aids, fabrication, and testing during the production of turbine disk runners on a 3-Axis CNC machine. This was done by comparing the initial workpiece setup time and the workpiece clamping transfer time using CPIP production aids versus not using CPIP production aids. The results showed that the designed CPIP Fixture significantly reduced the CPIP manufacturing Cycle Time, with a reduction of 63.11% in the initial workpiece setup time and 83.55% during the clamping transfer process.

Abstract

Analisis faktor keamanan (FoS) dan distribusi tegangan pada balok profil-I baja AISI 304 dengan beban terpusat dilakukan menggunakan simulasi Finite Element Method (FEM) di SolidWorks Simulation. Model uji berupa balok IPE-160 sepanjang 1.000 mm dengan kedua ujung ditumpu kaku dan pembebanan 1.000 kgf (sekitar 9,81 kN) di tengah bentang. Hasil menunjukkan tegangan von Mises maksimum 30,72 MPa, jauh di bawah tegangan luluh AISI 304 sekitar 206 MPa, sehingga diperoleh FoS minimum 6,7, melampaui batas minimum Eurocode 3 (lebih dari sama dengan 2,0). Defleksi maksimum 1,25 mm juga berada jauh di bawah batas layanan L/360 sekitar 2,78 mm, menegaskan terpenuhinya kriteria serviceability. Kontur tegangan memperlihatkan konsentrasi maksimum pada zona pertemuan web–flange tepat di bawah titik beban, selaras dengan prediksi teori balok. Reaksi tumpuan terdistribusi merata (±4.905 N per tumpuan) mengonfirmasi keseimbangan statik. Temuan mengindikasikan bahwa balok I AISI 304 aman dan efisien untuk skenario beban terpusat yang dikaji. Kontribusi utama studi ini adalah pemetaan kuantitatif margin keselamatan dan lokasi kritis tegangan pada balok stainless austenitik, yang relevan sebagai rujukan desain berbasis FEM sesuai standar mutakhir.
