Abstract

Shaft and roll bending is an element of a machine used for rolling pipes, bending pipes to curved and formed the desired angle. Roll operations often accept the burden that intersect between the pipes and the roll. The load will result in stress and strain. To make roll work safely, the various stresses and strains that occur must be calculated by using numerical simulation software to determine stresses and strains that occur on the shaft and roll bending. The bending of the shaft caused by a given load on the axis is F = 3382.339 N, and the loading on the roll bending that occurs on the surface of the exposed pipes is equal to F = 3361.51 N. Distribution of maximum shear stress that occurs in the shaft mounted roll bending is = 135.3 MPa. The maximum shear stress distribution that occurs in roll bending is = 69.91 MPa. The maximum strain distribution that occurs in roll bending is max = 9.088 x10-3 Mpa, and the maximum strain distributionthat occurs in the shaft is  max = 2.507 x10-3 Mpa. With these results, shaft and roll bending can work safelybecause the voltage that occurs does not exceed the voltage that occurs on the shaft and roll.

Abstract

The development of Hydroulic Regenerative Shock Absorber starts with presenting theories that work, and simulates them with numerical computing software to becompare with conventional shock absorber systems. The generation energy of the regenerative suspension system is only effective for high amplitude. When the amplitude is low, the generation energy will decrease as a result of bidirectional rotation and inertial losses. The greater the generator rotation, the higher current, and power generation. In the HMERSA fluid flow simulation 1 input and single output using the Fluid SIM software. the input given is 3 Hz on the hydraulic cylinder that is on the 4-wheel vehicle. The simulation was done by changing the hydraulic circuit and adding a check valve mechanism so that the rotation of the hydraulic motor becomes unidirectional. In this simulation there is no generator component because in the Fluidsim software does not provide these components in the simulation. The simulation using the Fluidsim software is intended to find out whether the hydraulic circuit that has been designed runs well marked by the rotation of the one-way hydraulic motor rotation. The design design of HMERSA with 1 input 1 output can run well marked from the rotation of the hydraulic motor into one direction when the conditions are expansion or compression. The torque value that occurs during an expansion condition is 1.1 Nm, while for the torque value that occurs when the compression condition is 1.6 Nm. The power generated from the hydraulic motor when the expansion condition is 1.6 Watt. Whereas when the compression condition of the power of the hydraulic motor that can be produced is 4 Watt.

Abstract

Boom cylinder is a component of the excavator which is located on the left and right front. This component works to move the bucket optimally by utilizing hydraulic oil flow. Boom cylinders will experience a decrease in performance if there are problems and damage to their internal parts. This Scientific Paper Analysis collects data from various direct observations in the field and makes improvements to the tools. boom cylinder malfunctions get information from the chief maintenance mechanic and experienced mechanics. This can be a basic problem of analysis, performance disturbances in the boom cylinder components can be caused by several factors, one of which is contamination that occurs in the boom cylinder. there is no inside and outside, and the occurrence of overheating in the boom part of the cylinder components. The causes of damage to the cylinder boom are very diverse, this can occur due to certain factors, including the use of the unit by the operator, steep work terrain and many other determining factors that damage the components of this cylinder boom. The problem of thinning the cylinder boom can be carried out according to procedures, capacity that is not excessive according to work standards, and daily, daily and monthly maintenance.

Abstract

Agricultural technology to support the agricultural sector, especially peaty paddy fields, should be developed, because peat land with a thickness of less than one meter has been recommended for rice crops. supported by a potential peatland area of ​​up to 21 million Ha or 10.8% of Indonesia's land area. Currently, peatland farming communities use sickles to harvest rice and hoes to cultivate the land. So far, hand tractor finned wheel drive technology has been widely used for cultivating wet paddy fields, whereas in conditions of peaty paddy fields it has not been able to be used because of the high level of sinkage and wheel slip, for this reason a new model of wheel is needed that is capable of working in peaty paddy fields. The aim of the research is firstly to find the right model of driving wheel for use in peaty paddy fields, secondly a prototype driving wheel for peaty paddy fields, and thirdly to experimentally test the driving wheel. Research results (1) prototype with a driving wheel diameter of 35 cm and the number of fins is 8 for the standard fin type and for the double fin type the driving wheel diameter is 40 cm with 4 vertical arc fins, which are placed on the surface of the driving wheel. (2) Comparison with the same type of loading shows that the double fin type drive wheel has a relatively smaller level of wheel loading (around 20%) when compared to the standard type drive wheel. (3) The sinkage level of the standard type drive wheel has a smaller sinkage (around 10%) compared to the double finned wheel type, in tests with the same type of loading. test loads for wheels are 20 kg, 40 kg and 60 kg. The double fin type drive wheel is good for use in peaty paddy fields.

Abstract

Mobile application provides a spectrum of interactive and multimedia tools to improve the learning process. Unfortunately, this application not only brings benefits, but also portrays some flaws. Hence, this study aimed at finding out the strengths, weaknesses, opportunities, and threats that are potential from a newly-developed learning application named Haba Inggreh. This study belongs toqualitative deisgn, involving 29 students and 4 teachers from SMAN 1 Seunagan. Classroom observations and interviews were employed as the data collection techniques, and all the obtained data were analyzed using thematic analysis. The findings reveal that in terms of thestrength, both teachers and students agreed that the Haba Inggreh application enhances language acquisition. On the other hand, the weakness of this app is slow performance, which could frustrate the users, resulting in impeding effective learning. Furthermore, the opportunity of this app is that Haba Inggreh can be improved by raising interactivity and involvement. However, it also poses a threat, as using the app excessively for language learning is dangerous. Though Haba Inggreh offers helpful materials, language acquisition calls for real-world contact and immersion. Users could overuse the app and choose not to follow local wisdom.

Abstract

Kebutuhan bawang merah terus meningkat setiap tahunnya akan tetapi produksi bawang merah terhambat akibat kondisi iklim dan serangan penyakit. Aceh berpotensi sebagai wilayah pengembangan produksi bawang merah dan selaras dengan tujuan pemerintah Aceh untuk meningkatkan komoditas hortikultura. Tujuan kegiatan ini adalah meningkatkan produksi bawang merah dengan pengaplikasian Internet of Things (IoT) agar lingkungan dapat terkontrol baik dari kelembaban, suhu dan pengaturan penyiraman. Metode kegiatan meliputi sosialisasi, praktik budidaya bawang merah, penerapan IoT dan evaluasi. Hasil kegiatan ini menunjukkan bahwa pengetahuan dan kemampuan petani meningkat dalam budidaya bawang merah, baik secara teori dan praktik di lahan. Hasil evaluasi sebelum kegiatan sosialisasi menunjukkan 90% masyarakat belum memahami mengenai IoT dan pengaplikasiannya, kemudian setelah kegiatan kemampuan masyarakat meningkat dan memahami kinerja IoT, dimana 87% petani dapat memantau kondisi tanaman bawang merah secara lebih efisien dan 90% petani menyatakan bahwa air yang digunakan lebih hemat dan efektif dengan sistem irigasi berbasis IoT. Budidaya bawang merah berbasis IoT diharapkan mendukung pertanian modern yang berkelanjutan serta meningkatkan produktivitas dan pendapatan petani. Pengembangan dan perluasan teknologi ini disarankan untuk menjangkau lebih banyak petani di daerah lain.
