Abstract

Lack of water is one of the problems in the agricultural sector. The location of the farm which is located above the water source causes difficulties in flowing the rice field area. During the dry season, farmers are forced to lift water using a water pump. Therefore, a more economical water pump is needed, one of that is a spiral pump which is driven by an undershot waterwheel. The results of the undershot waterwheel design obtained a diameter of 1 m, a width of 1.15 m, and a blade area of 0.459 m2. The frame of the wheel is made of plain concrete iron with a diameter of 8 mm, the blade of the wheel is made of 0.4 mm thick galvanized plate, the support for the pinwheel is made of angled iron with a size of 4 x 4 cm, while the shaft of the pinwheel is made of galvanized pipe with an outer diameter of 33.8 mm and 3.2 mm thick. From the test results, the wheel rotation is 15.2 rpm, torque is 9.5 Nm, wheel power is 15.11 watts, and the undershot waterwheel efficiency is 16.54%.

Abstract

Penelitian ini bertujuan untuk menghasilkan desain rangka sepeda listrik (e-bike) tipe double cradle yang memenuhi kriteria kuat dan ringan, tanpa mengesampingkan standar keselamatan berkendara. Kontribusi utama penelitian ini adalah menyediakan data teknis yang tervalidasi mengenai geometri dan material yang paling optimal untuk struktur kendaraan listrik ringan. Metode yang digunakan adalah pendekatan simulasi digital menggunakan perangkat lunak SolidWorks 2021. Melalui perangkat ini, dilakukan uji beban virtual terhadap dua variasi panjang rangka, yaitu 965 mm (Variasi 1) dan 950 mm (Variasi 2), dengan beban pengendara sebesar 80 kg. Pengujian mencakup dua jenis material logam, yaitu ASTM A36 dan AISI 304, untuk membandingkan tingkat ketahanannya. Hasil penelitian menunjukkan bahwa Variasi 2 dengan material ASTM A36 merupakan pilihan terbaik. Desain ini menghasilkan tegangan sisa sebesar 28,587 MPa dan perubahan bentuk (deformasi) yang sangat minim, yaitu 0,048 mm. Dengan angka keamanan (factor of safety) mencapai 8,7 dan total berat rangka 15,8 kg, desain ini dinyatakan sangat aman dan efisien untuk dikembangkan lebih lanjut sebagai standar rangka sepeda listrik yang tangguh.

Abstract

This study compares the effectiveness of Variable Helix Angle (VHA) and Normal Helix Angle (NHA) end mills in controlling regenerative chatter during CNC milling of stainless steel 304. Experiments were conducted across a range of cutting parameters, including cutting speed, feed per tooth, and axial depth of cut, using VHA and NHA tools with identical basic geometries except for the helix angle. Measurements were obtained for vibration signals using an accelerometer, machined surface roughness (Ra), and tool wear. Signal analyses, including Fast Fourier Transform (FFT) and Power Spectral Density (PSD), experimental construction of stability lobe diagrams, and statistical evaluation using ANOVA, were employed to assess the influence of helix angle on stability limits and surface quality. The results are expected to determine whether VHA tools offer significant improvements in chatter suppression and expand the stable cutting region compared to NHA tools, as well as their implications for productivity and tool life when machining SS304. The findings provide practical recommendations for selecting cutter geometry in industrial applications where regenerative chatter poses a critical challenge.

Abstract

The design of components for vehicles used in tourist areas must be efficient, safe, and economical. The steering knuckle is a vital component in the vehicle's suspension and steering systems, playing a crucial role in transferring loads, connecting the wheel to the steering mechanism, and supporting braking components. This research aims to design, analyze, and fabricate a steering knuckle for a mini tourist car with a total mass of 300 kg using plain carbon steel. The design and strength analysis were evaluated using the open-source Finite Element Analysis (FEA) software PrePoMax to investigate stress distribution, deformation, and the factor of safety. The FEA results showed a maximum Von Mises stress of 86.27 MPa, well below the material's yield strength, a maximum deformation of 0.126 mm, and a minimum safety factor of 2.72, confirming a robust design. The component was designed to accommodate a 30204 tapered roller bearing. The fabrication process, encompassing cutting, machining, and welding, successfully produced a functional prototype validated through direct installation and load testing on the vehicle. This study confirms that plain carbon steel is a reliable and economical material for structural components in lightweight vehicle applications and provides a pragmatic engineering framework for developing cost-effective automotive components.

Abstract

The residents of Songgon District, who are generally farmers, make rice fields and plantations dominant in the community's economy. Once a year durian trees can be harvested and once a rice harvest, this makes agriculture and plantations the backbone of the source of life for Songgon District, which results in the villagers' income being only annual. So that the economic sector that is able to generate income for villagers both on a monthly and daily basis, such as in the fisheries and tourism sectors, needs special attention for the development of the rural economy, given the huge potential possessed by Songgon District. Garbage is a major problem in this place, for example on the banks of the Binau river which is located in Songgon Village/District, opposite the Songgon District Office to be exact, which used to be full of piles of garbage. Residents around are reluctant to pass or do activities around the watershed (DAS). Therefore we are here with Pertamina Muda present in the development of the river fisheries sector such as controlled fish stocking (pioneered by Mr. Wibi Untoro) in the Binau river flow path and by utilizing Hydro Vortex Energy is a solution that can be implemented because it is proven to improve the community's economy and public awareness of the environment.
