Abstract

The hydraulic system is a power transmission system by using the compressive energy of the fluid into mechanical energy to obtain a power greater than the initial power released. The press machine is one of the pieces of equipment that apply the hydraulic system. In the process of making laminated bamboo, the bamboo gluing technique is assisted using a press machine. Based on observations, the press machine used is a manual press machine, so the pressing process is not efficient. This study aims to increase the effectiveness of pressing laminated bamboo. The results of the study found that the press machine has 4 hydraulic cylinders so the pressing process can be carried out at several points simultaneously. The results of the hydraulic system analysis diagram show hydraulic cylinder moves in 16,9 seconds with a pressure of 100 bar, so the pressing process is fast. Mathematical calculations produce data, a hydraulic gear pump with a displacement of 13 cc/rev, electric motor power of 3,7 kW, hydraulic cylinder diameter of 63 mm, cylinder rod of 35 mm, rod of 400 mm, and a hydraulic tank capacity of 12 liters.

Abstract

Panti Asuhan dan Pondok Lansia "Al Maa'uun" merupakan lembaga sosial yang berperan untuk memberikan pelayanan kesejahteraan sosial bagi masyarakat. Panti Asuhan Yatim dan Pondok Lansia Al Maa’uun telah berdiri sejak tahun 2019 bertempat di dusun Bakalan, Sapuran, Wonosobo, Jawa Tengah. Kegiatan yang telah dilakukan adalah bercocok tanam berbagai sayuran dan pengolahan carica. Kegiatan bercocok taman yang dilakukan tidak selalu menghasilkan panen yang baik. Permasalah diantaranya adalah hama penyakit pada tanaman yang penanggulangannya sangat sulit diatasi. Program pengabdian pada masyarakat ini difokuskan pada usaha untuk meminimalkan serangan hama dan meningkatkan produksi tanaman adalah dengan penggunaan green house untuk tanaman buah melon, khususnya pada pembuatan sistem perpipaan menggunakan sistem PJC. Pemasangan selang drip dilakukan sebelum penanaman dengan tujuan untuk mengalirkan nutrisi dari fertikid nutrisi melalui pipa utama untuk sampai ke tanaman. Selang drip dihubungkan dengan selang penetes (drib tube) yang dipasang di sepanjang selang cabang.

Abstract

The global shift towards electrification has extended its reach to non-road mobile machinery, with a primary focus on agricultural applications. This growing trend reflects the larger shift towards sustainability and the minimization of environmental effects. Electric tractors and other farm machinery have gained popularity due to their environmental benefits, cost savings, and technological advancements. The electric non-road vehicles are not only quieter and more environmentally friendly but also offer the potential for reduced operational costs, making them a compelling choice for farmers looking to modernise their equipment while adhering to stringent environmental regulations. Thus, the concept of an electric tractor becomes an important topic to be discussed. This paper will discuss the development of tractors in Indonesia and proposed design for electric tractors that are suitable for Indonesia to support sustainable farming.

Abstract

The Vocational School Education is a university-level higher education program that places greater emphasis on practical fieldwork relevant to industry needs rather than academic theoretical knowledge. In Indonesia, vocational school programs or diplomas play a crucial role in the development and scientific research. The creation of a mini excavator model is a research and innovation project aimed at supporting students' practical training activities. The development of hydraulic swing components is used to enhance the components of the mini excavator model, which will later be expanded for educational purposes in the hydraulic drive system. The ultimate goal of this research is to manufacture hydraulic swing components that will be installed in the mini excavator model, with the final objective being to determine the pressure and rpm performance of these hydraulic swing components. Based on the conducted research, operating the mini excavator model requires a radius dimension or distance from the center point to the warning line of 3 m², and the maximum pressure for the mini excavator model is 150 kgf/cm², resulting in 11.17 rpm. Meanwhile, the allowable pressure for operating the hydraulic swing components in the mini excavator model is 100 kgf/cm², resulting in 8.54.

Abstract

As the solidification reaches the hot spot area, no molten metal remains and shrinkage is formed. To anticipate the shrinkage, a riser is added to the casting system. An optimal riser design would produce free shrinkage components. One of the factors that affect riser efficiency is the riser shape. This study aims to find the most efficient side riser shape by using simulation software. The riser shape of tubes, tubes with a half sphere on top, hemispheres, conical tubes, tubes with an oval cross-section, and cubes are used in this experiment, with the volume of all risers kept constant. The most efficient shape of the riser is the tube. The tube riser produces a larger modulus. The tube riser generated directional solidification. The same pattern can be seen in the niyama criteria and solidification temperature, where the tube riser has a more continuous pattern compared to other riser shapes.
