Abstract

The increasing interest in coffee in all circles means that coffee production and quality must always increase due to consumer demands. One way to maintain the quality of coffee beans is by breaking them down using a huller machine. This research aims to improve the optimization of coffee machines by modifying the cylinder blades of huller machines with variations of 3, 4, 5, and 7 cylinder blades in terms of static loading design and quality and production capacity of coffee bean breaking. The experiment was carried out using 400 rpm and breaking 10kg of dry coffee cherries every time the sample was taken. The research results show that the best sample collection is the variation of 3 cylindrical blades with the maximum stress and lowest deformation values of 6.67 MPa and 0.000737 mm. In terms of production quality, it shows that the best sampling was the three cylindrical blade variations with 50% whole and good coffee beans. In terms of production capacity, the most significant capacity was the seven cylindrical blade variations with a value of 294.11 kg/hour. Sampling from the four most optimal variations uses the SAW (Sample Additive Weighting) method. The most optimal result from the 4 test criteria, the variation of 3 cylindrical blades is the best because it has the highest score with a value of 0.9754.

Abstract

Plastic is a polymer that has unique and extraordinary characteristic properties. With a binder (plastic) can be combined with metal elements, namely aluminum. Aluminum is chosen as an alloy material because it has good strength and tenacity. Metal alloy plastic can be processed by a method called injection molding. Injection molding is a process used in making plastic products. This research was conducted with barrel temperature, injection pressure and cooling time process variables. While the response variable is warpage defects. This study aims to determine the effect of variations in process parameters is barrel temperature, injection pressure, cooling time on warpage defects in injection molding products with Al-PP alloy material, and find out the optimum variation of parameters in the injection molding process. The results showed that barrel temperature had an effect of 91.62% on the value of warpage defect response, this condition can be observed as the level barrel temperature increases, the value of warpage defects also increases. The effect of 6.43% injection pressure on the value of warpage defects due to an increase in each injection pressure level will reduce the chance of warpage defects. The effect of cooling time parameters is 1.78% on the value of warpage defects, which means that the longer the cooling time, the greater the response or warpage produced. The optimum variation of parameters in the injection molding process in the ASTM A370 test specimen in barrel temperature parameters at level 1 is 150 oC, the injection pressure parameter at level 3 is 11 bar and the cooling time parameter at level 1 is 15 seconds.

Abstract

This paper presents a community engagement initiative in Kuwon Village, Magetan Regency, aimed at enhancing agricultural productivity through compost production mechanization. The project, a collaboration between university researchers and local farmers, introduced organic composting techniques using a specially designed compost chopper machine. The initiative sought to address the challenges of high fertilizer costs and limited subsidized fertilizers, promoting sustainable agricultural practices and improving farmers' livelihoods. The primary goal was to provide an efficient, cost-effective method for producing organic compost, reducing dependency on chemical fertilizers, and improving soil health. The project followed a participatory approach, involving farmers at every stage—from needs assessment to design, fabrication, training, and implementation—ensuring solutions suited to the local community's needs. The compost chopper machine reduced time and labor in compost production, and farmers reported improved soil health and higher crop yields. The project also fostered community collaboration as farmers worked together to adopt new practices. Economic benefits included lower input costs and increased income from higher productivity. The success of this initiative highlights the potential of combining technological innovation with community involvement to tackle challenges faced by rural farmers in Indonesia, promoting sustainable agricultural development and improving livelihoods.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas penggunaan mesin gerinda camshaft di bengkel Jasa Ibu dengan menggunakan metode Overall Equipment Effectiveness (OEE). Metode OEE mengukur tiga komponen utama yaitu ketersediaan, kinerja, dan tingkat kualitas, untuk mengevaluasi seberapa dekat proses produksi mendekati kondisi optimal. Hasil analisis menunjukkan bahwa rata-rata nilai OEE pada mesin gerinda camshaft berada di atas standar global sebesar 85%, dengan nilai rata-rata ketersediaan 94,69%, kinerja 99,09%, dan kualitas 100%. Walaupun sebagian besar indikator melebihi standar yang ditetapkan, penurunan efektivitas tercatat pada beberapa hari tertentu, terutama disebabkan oleh waktu henti mesin dan penurunan kecepatan produksi. Untuk mengidentifikasi penyebab penurunan ini, dilakukan analisis lebih lanjut menggunakan diagram pareto dan fishbone diagram. Penelitian ini menyarankan beberapa perbaikan, termasuk perawatan rutin yang lebih sistematis, penyesuaian waktu proses, dan peningkatan keandalan mesin.

Abstract

This study integrates the Taguchi method and 3D digital metrology to improve dimensional accuracy in the Polylactic Acid (PLA)-based Fused Deposition Modelling (FDM) process. The research focuses on the fabrication of vibration-damping roller components in a Continuously Variable Transmission (CVT) system that demands high geometric precision. A Taguchi L9 experimental design was used to analyze the effects of layer height, extrusion temperature, and filling density on the volume deviation of the printed product. The evaluation was conducted using 3D scanning and analyzed using the Signal-to-Noise (S/N) ratio and Analysis of Variance (ANOVA). The optimal parameter combination was obtained at a layer height of 0.25 mm and an extrusion temperature of 220 °C, resulting in the minimum volume deviation and the highest process stability. The ANOVA results identified layer height as the most dominant factor, followed by extrusion temperature, while filling density had a relatively small effect. Validation tests showed good agreement between the predictions and the experimental results. These findings confirm the effectiveness of integrating the Taguchi method with digital metrology in supporting the development of PLA-based precision additive manufacturing for sustainable automotive component applications.This study integrates the Taguchi method and 3D digital metrology to improve dimensional accuracy in the Polylactic Acid (PLA)-based Fused Deposition Modelling (FDM) process.
