Abstract

Crane hook strength analysis is an effort to minimize accidents and work failures when used in moving goods that tend to have heavy loads. Apart from that, the analysis is also used as a benchmark for the crane hook safety level which can be identified through the accompanying structures. This study aims to determine the strength of the crane hook with various geometric shapes and sizes, namely the ST E 355 crane hook with the DIN 15401 standard, hereinafter referred to as the original size and half of the original size. The strength in question consists of deformation, stress and safety factor. This research begins with the design process using an autodesk inventor, then proceeds to the simulation and analysis process through ANSYS. The results obtained are the crane hook with the original size has the best strength. This is indicated by a small deformation with a value of 0.82214 mm, a low stress value of 264.14 Mpa, and a high safety factor with a value of 2.668903.

Abstract

Plastic waste is a major problem faced by Indonesia, especially in big cities which have a high level of activity and density as well as rapid infrastructure development. To overcome this, environmental experts and scientists from various disciplines have conducted various studies and actions. One alternative for handling plastic waste is to carry out a recycling process (recycle) through pyrolysis. This study aims to analyze liquid fuel from the results of pyrolysis of polyethylene plastic waste. This research is an experimental research with a quantitative approach. The data analysis technique used is data analysis using descriptive techniques. The pyrolysis results obtained consisted of Premium Alternative Fuels producing a density of ± 1060 ml, Kerosene Alternative Fuels producing a density of ± 1480 ml and Alternative Diesel Fuels producing a density of ± 1700 ml.

Abstract

Tujuan dari penelitian ini adalah mengetahui bentuk cacat makro akibat holding time pada peleburan coran Al-Si. Metode penelitian yang digunakan dalam penelitian ini adalah rancangan penelitian eksperimental dengan jenis pendekatan kuantitatif. Teknik analisis data yang digunakan dalam penelitian ini adalah analisis deskriptif yang dilakukan dengan cara merangkum hasil penelitian berdasarkan pengamatan yang telah dilakukan. Pengamatan cacat makro diamati dengan foto makro. Secara umum cacat makro yang terjadi adalah lubang jarum, pelekat, rontok cetakan, salah alir dan sumbat dingin. Secara khusus, terjadi cacat porositas pada spesimen dengan variasi holding time peleburan 15, 25, dan 35 menit pada pengecoran logam Al-Si secara berurutan adalah 4,22 %, 3,07%, dan 3,08%.
