Abstract

Abstract  Sandals are a need for clothing for humans which are often used in daily activities, sandals are also protective feet for humans when on the move. Sandals have several types, in this study the authors focused on sandals made of EVA sponge. In the process of making sandals, several machines or tools are needed to make sandals, while this research will focus on the sandal adhesive machine. The purpose of this research is to get perfect gluing results in making sandals using a roll machine which is easy to operate and maintain. The method used is gluing the sandal material through a rolling process which is carried out by placing the sandal material on the guide table, then the sandal material is entered between a pair of pulling rolls and then forwarded to the next pair of rolls for the gluing or pressing process. The end result of the design of this sandal pressing machine can produce sandals production capacity of up to 60 sandals/minute with a shear stress strength of 0.1505 N/mm².

Abstract

Pelet merupakan bentuk makanan ikan buatan yang terdiri dari beberapa macam bahan yang di ramu dan di jadikan adonan, kemudian di cetak sehingga membentuk merupakan batangan kecil - kecil. Untuk mencetak adonan tersebut, dibutuhkan sebuah mesin yang mampu membuat pelet pakan ikan. Mesin pembuat pelet pakan ikan merupakan teknologi  tepat guna yang digunakan untuk membuat pelet pakan ikan yang bertujuan untuk membantu para petani ikan agar dapat memproduksi pakan ikan sendiri, sehingga dapat mengurangi beban biaya. Selain untuk membantu para petani, mesin ini dibuat juga untuk mengatasi masalah yang ada seperti; pemasukan adonan yang harus di tumbuk sehingga mengurangi tingkat efektifitas waktu. Mesin pembuat pelet pakan ikan ini dilengkapi dengan roll pendorong yang dimaksudkan dapat mengatasi masalah tersebut. Metode rancang bangun ini dengan observasi,artenatif desain, pemilihan desain perhitungan serta gambar, pembuatan komponen perakitan, modifikasi, ujicoba dan pengambilan data. Cara kerjanya yaitu dengan memasukkan adonan yang telah tercampur sedikit demi sedikit secara kontinu. Setelah adonan masuk melalui hopper, lalu roll akan mendorong adonan masuk menuju tabung ektruder. Kemudian adonan akan di ektrusi dan akan terdorong keluar melalui cetakan. Adonan yang keluar melalui cetakan akan di potong oleh pisau pemotong, dan terbentuklah pelet berdasarkan ukuran yang diinginkan. Mesin ini berkapasitas 15 kg/jam dengan spesifikasi dimensi panjang 800 mm, lebar 700 mm, dan tinggi 415 mm dengan menggunakan roll dan digerakkan dengan motor bensin.

Abstract

The process of finishing brake shoe products in PT XYZ's die casting department experienced waste using M steel shot 230 sand which reached 4,125 kg throughout 2020 and the amount of sand that fell to the floor was 36 kg per shift. The reason is that the unloading process is still manual by shaking the brake shoe jig for 2 seconds/jig then immediately pouring the brake shoe into the polybox which has holes and does not have a sand container. The use of a sieving machine is expected to reduce lost sand so that productivity can increase. The test parameters are the rotation of the motor which is regulated through an inverter of 5.5 Hz, 6 Hz, and 6.5 Hz for the time of the brake shoe sifting process, as well as the amount of sand scattered and carried by the brake shoe against the cost of purchasing sand. The results showed that productivity increased by 5.56%, the cost down of purchasing sand by up to 75.40%, and environmental cleanliness increased by 92.87%. The increase above based on Pareto analysis is included in the significant category because it meets the 20/80 rule.
