Abstract

Penelitian ini bertujuan untuk  menguji efektiftas model  Problem Based Learning (PBL) dan pengaruh polah asuh terhadap keterampilan proses sains (KPS) peserta didik.  Sampel penelitian ini adalah 80 peserta didik sekolah MTs yang ada di Kabupaten Konawe. Penelitian ini merupakan penelitian eskperimen.  Sampel terdiri dari: 19 orang yang  mendapatkan  pola asuh otoriter, 27  pola asuh demokratis,  dan 24  pola asuh permisif. Sampel di bagi secara acak ke dalam dua kelas belajar  berdasarkan jenis pola asuh secara seimbang. Setiap kelas berjumlah 40 orang, dan salah satu keals mendapatkan lingkungan belajar PBL dan satu kelas lainnya diberikan pembelajaran konvensional.  Hasil analisis data menunjukkan bahwa  model PBL lebih efektif dibandingkan konvensional dalam mengembangkan KPS peserta didik. Pola asuh berpengaruh signifikant pada pengembangan KPS. Peserta didik dengan pola asuh demokratis   lebih tinggi secara signifikan dibandingkan pola asuh permisif dan otoriter, tetapi antara otoriter dan permitif tidak memberikan perbedaan yang berarti. Tidak ada pengaruh interaksi yang signifikan antara model pembelajaran dan pola asuh orang tua terhadap keterampilan proses sains peserta didik.

Abstract

Kurrak Village, Polewali Mandar Regency is a coffee-producing village that has the opportunity to develop an organic coffee agro-industry to support the realization of a green economy, namely a program to improve the Indonesian economy by focusing on environmentally sound activities. Some of the problems faced by coffee farming communities in the region include how to harvest and handle post-harvest coffee. The purpose of this community service program (PKM) is to improve the ability of the Kurrak village coffee farming community in post-harvest processing and to increase the role of micro, small and medium enterprises (UMKM) in establishing partnerships with coffee farmers. The method of implementing the activity is by counseling and practice with several stages including preparation, implementation and evaluation of the program. The PKM activity was carried out in a coffee plantation for residents in Kurrak village, attended by 25 representatives of the Kurrak village community. The results of the PKM activities showed that the activity participants had the ability to apply post-harvest coffee processing techniques, the enthusiasm and motivation of the farmer members increased and they began to activate the collaboration of MSMEs and coffee farmers in Kurrak village.

Abstract

Maintenance of heavy equipment units is required to maintain and ensure the performance of the unit in ready-to-use condition. Damage that occurs, especially in the fuel system line, often causes the excavator unit to become low power, even when the engine turns off. In PT XYZ, damage of the fuel system often occurs causing the unit to undergo unscheduled breakdown. By using the fishbone method to find the cause of the problem, it was found that the existing treatments were not optimal so that problems that started to appear were not immediately followed up. By monitoring the maintenance schedule and accelerating the replacement of fuel filters, unscheduled repairs can be overcome and the physical availability target is achieved..

Abstract

This article describes an experimental investigation into optimizing spot welding resistance (RSW) using a spot-welding machine equipped with a dual-electrode Pressure Force System (PFS). The optimization procedure entails the incorporation of SPCC-SD (JIS G 3141), a low-carbon steel that finds extensive application in the automotive sector. With the widespread use of SPCC-SD steel, RSW is an essential process in the automotive industry for assembling body components. This study employs the Box-Behnken Response Surface Methodology (Box-Behnken-RSM) to optimize the tensile strength load (TS-load), a critical parameter in RSW, through a meticulous analysis of the interplay between Holding Time, Squeezing Time, Welding Current, and Welding Time. Through the methodical design of experiments, the collection of Tensile Strength Load data, and the application of statistical modeling via RSM, this study employs SPCC-SD steel to determine the optimal values for these variables in RSW. The results above readily offer a valuable understanding of the most significant determinants and their interrelationships, thus facilitating advancements in welding methodologies and quality control in the automotive manufacturing sector. This study employs the Box-Behnken Response Surface Methodology to investigate the impacts and interrelationships of different parameters thoroughly. It aims to enhance the TS-load using SPCC-SD steel during the resistance spot welding procedure. This research contributes to advancing welding methodologies employed in the automotive manufacturing sector.

Abstract

The persistent challenges in material forming processes arise from recurrent issues encountered during the deep drawing process, particularly involving cracks and deviations from standard thickness dimensions. This article investigates the deep drawing process using both experimental and numerical methodologies. The experimental approach employs a 40-ton capacity power press machine, while the numerical method utilizes the ABAQUS student version software. SPCC-SD (JIS G3141) is the selected material for producing a Dop-pipe 2-inch diameter pipe cap in both approaches. Noteworthy findings include the highest positive and negative correlations observed in elements E 46 and E 48, with values of 0.715 and -0.933, respectively. Minimal disparities, averaging around 4.6% for all components, were evident between the experimental and numerical methodologies. The numerical approach yielded predictive results identifying potential issues in elements E 47 and E 48. This observation did not reveal instances of tearing failure but instead showcased an increase in thickness due to a higher axial force between the dies and punched-in components. The study successfully and accurately predicted product thickness for all components, presenting a contrast with outcomes obtained through the experimental method. Furthermore, this research advances the deep drawing process, extending its applicability to broader material forming applications and ultimately enhancing overall production process efficiency.

Abstract

This article investigates the challenges and solutions within the deep drawing process, focusing on issues like cracks and deviations from standard thickness dimensions. Utilizing both experimental methods with a 40-ton power press machine and numerical simulations via ABAQUS software, the study uses SPCC-SD steel to produce a Dop-pipe 1-inch diameter pipe cap. Key findings reveal significant correlations in elements E-90 and E-91, with minimal disparities of around 4.5% between experimental and numerical approaches, showcasing the accuracy of numerical predictions. Notably, the numerical simulations identify potential issues such as increased thickness due to higher axial forces, providing valuable insights for process optimization and defect reduction. By advancing the deep drawing process and extending its applicability to broader material-forming applications, this research contributes significantly to enhancing production efficiency and improving manufacturing practices, emphasizing the importance of simulation-driven approaches in achieving precision and quality enhancement in complex manufacturing processes.

Abstract

Industrial developments, especially in the manufacturing and construction sectors, recognize L-hanger ducting as a critical component in HVAC (heating ventilation and air conditioning) ducting systems, which play a role in supporting and stabilizing air ducts. The L-Hanger ducting manufacturing process involves a series of stages, such as shearing, blanking, piercing, trimming, and bending processes. This research focuses on the design and simulation of dies and punches for piercing, blanking, and bending processes using 1.6 mm-thick SPCC-SD material. The aim of this research is to design and analyze progressive dies in order to increase the efficiency of the production process. A comprehensive calculation of the forces involved in the shearing, blanking, piercing, trimming, and bending processes is required in order to predict press machine tonnage requirements to support the production process. This research applies theoretical and numerical validation approaches. Theoretical analysis is used to calculate the overall forces, which are then compared with numerical results and verified through an experimental approach. By understanding and optimizing the design of progressive dies, it is hoped that we can increase the production efficiency of L-hanger Ducting and expand knowledge in the field of metal forming, contributing to the metal forming industry and supporting the development of science.
