Abstract

Penggunaan alat peraga sebagai media pembelajaran khususnya untuk ilmu bahan masih jarang digunakan oleh dosen. Kebanyakan dosen lebih suka mengajarkan secara verbal kepada mahasiswa tanpa ada alat peraga yang mendukung. Salah satu penyebabnya adalah tidak berjalannya alat peraga seperti alat peraga tungku pengecoran atau dapur peleburan. Tujuan tugas akhir ini untuk menciptakan Tungku Pengecoran logam non ferro (aluminium (Al) dan timah) dengan kapasitas 30 kg dilengkapi digital temperatur kontrol. Berdasarkan latar belakang diatas perancangan ini menggunakan metode rekayasa. Metode rekayasa adalah metode yang menerapkan ilmu pengetahuan menjadi suatu rancangan guna mendapatkan kinerja sesuai dengan persyaratan yang ditentukan. Hasil dalam perancangan ini adalah terciptanya Tungku Pengecoran logam non ferro (aluminium (Al) dan timah) dengan kapasitas 30 kg dilengkapi digital temperatur kontrol. Alat ini dapat menghasilkan pengecoran dengan temperatur logam aluminium 680 0C dan logam timah dengan temperatur 250 0C, alat ini juga dilengkapi digital temperatur kontrol (termokopel) sehingga dapat mengetahui temperatur yang tepat untuk meminimalisir cacat porositas.

Abstract

The sand sieving process is an activity that we often encounter in infrastructure development projects. But in the case of observations, problems are often encountered where workers still rely on simple or manual equipment. Based on the observations of the cases found, a semi-automatic sand sieving machine will be designed to help construction workers. In the process of making a sand sieve machine using a 9° sieve tilt angle with a sieve area of ​​3250 cm² and using a 0.5 cm x 0.5 cm mesh type. The driving source of the sand sieving machine uses an AC 0.5 HP electric motor with 1420 rpm. The eccentric shaft has a rotational speed of 115.36 rpm after receiving rotation from the AC motor. There are several tests on the sand sieving machine including tool functional testing, tool feasibility testing, and tool testing. In the functional test of the tool, testing all parts of the sand sieving machine obtained an average test value of 95%, in the feasibility test of the tool an average value of 100% was obtained, with a score of 4 and for testing the tool which included sand sieving, the average value has obtained the average of fine sand testing is 16.46 Kg and coarse sand is 3.53 Kg in 17.48 seconds, so it can be seen that the sand sieving machine can work optimally.

Abstract

The development of a plastic waste chopper machine with a gearbox transmission system was carried out because in previous studies there were still shortcomings, namely not being able to operate optimally because during the enumeration of plastic waste there was often a slip on the v-belt. So that this development is carried out using a gearbox transmission system so that the rotation when chopping is more leverage. The research method used is the R&D (research and development) method, a method or step to produce new products or develop existing products, and is used to test the effectiveness of the product. For engine specifications, it uses an electric motor with a speed of 1400 rpm, and a gearbox transmission system with a ratio of 1:50 as a transmission between the motor and the blade shaft. This study uses a type of PET plastic glass waste to be chopped. The results of the minimum engine speed of 16.6 rpm, gearbox output rotation of 28 rpm, rotation of the knife shaft 27 rpm, the value of the force on the count of 9.8 N, the pulley rotation of 1200 rpm, the ratio of the chain rotation speed of 1.037 and the number of connected sprockets. the gearbox has 46 teeth, while the sprocket connected to the blade shaft has 44 teeth. So that the resulting engine capacity is 1.02 kg/hour. In addition to the results of machine calculations, machine validation tests were also carried out that for the engine design assessment of 81.25% with very good criteria, engine function of 91.6% with very good criteria, while the calculation of machine capacity was 85% with very good criteria.
