Abstract

Proses pemasukan material jenis Ferrite Ni-Zn series secara manual pada mesin press berkapasitas 10 tonase dan 20 tonase dari tempat bak penampung ke mesin press dengan material berceceran rata-rata 8 kg dalam sehari di lantai produksi. Sampai di mesin press, operator naik ke mesin untuk memasukkan raw material ke bagian hopper mesin. Proses tersebut membutuhkan waktu 9,62 menit. Untuk mengurangi kecelakaan kerja, efisiensi dalam penggunaan material dan waktu maka diperlukan inovasi material handling otomatis dengan sistem vacuum. Spesifikasi alat inovasi material handling berdimensi alat 8,258 x 0,995 x 3,241 m3, motor sebesar 2 HP bertekanan 15 Kpa, MCB 3 phase 13 Ampere dan 1 phase 1,95 Ampere, peletakan sensor di setiap hopper, katup kontrol udara, silinder pneumatik untuk membuka dan menutup saluran udara secara otomatis. Berdasarkan flow simulation Solidworks dengan spesifikasi alat tersebut dapat menyalurkan raw material Ferrite Ni-Zn series bermassa jenis rata-rata 3580 kg/m3, berkecepatan alir 0.51 m/s secara kontinu dan tanpa ada material yang tercecer di lantai produksi.

Abstract

In the world of the plantation industry, to get a maximum harvest, the main factor that needs to be considered is the way of harvesting. An efficient, inexpensive, and effective harvesting process is the main thing that must be achieved. Indonesia as one of the world's palm oil-producing countries together with the Palm Oil Plantation Fund Management Agency (BPDPKS) continues to develop ways to optimize its palm oil production process. The harvesting process today still uses many manual methods using sickles and dodos. Some palm oil harvesting tools are already motorized, however, existing tools still have disadvantages in terms of price and vibration in the shaft. In this article, the author successfully applied the Quality Function Deployment (QFD) method and designed a motorized palm harvester where vibrations from the motor can be reduced by moving the motor's position using a Flexible shaft. Further modifying the gearbox from the material, gear shape, and some elements of the process engine makes the gearbox lightweight and have a small vibration. This study aims to make a motorized palm harvesting tool that can be used to harvest palm fruit quickly and easily. Another thing to aim for is to get a cheap motorized palm oil harvesting machine because all the parts are designed and produced independently and have low vibration. Experiments conducted at the Professional Services Cooperative (KJP) Cipta Prima Sejahtera Banjarmasin obtained a palm oil harvesting machine that had been designed to have a low vibration acceleration value, has easy maintenance, is lighter than existing motorized palm cutting tools, and the speed of cutting branches is many and fast compared to manual dodos cutting tools.

Abstract

One of the steps after the electroplating/coating process on the product is the drying process. In Micro, Small and Medium Enterprises, the drying process on CIV KG 0741 bolts with a diameter of 10 mm and a length of 20 mm requires a drying time of 6 hours. Drying simply and naturally has limitations, requiring a large drying area depending on the weather, time and temperature, which cannot be controlled. A simple automatic dryer is needed using a single-phase electric power source and simple and ergonomic maintenance methods to obtain a quality product with a measurable drying duration. Design and analysis of drying on the dryer. The dryer with dimensions of 680 x 480 x 967.12 mm3 has a mass of 21.94 kg with a drum capacity of 20 kg. The motor propulsion used is 1 HP, 5.08 Nm of torque and capable of rotating at 1500 rpm with an effort of 39296.66 Joules. The dryer can dry as much as 20 kg of bolts in 5 minutes faster than solar energy, with a drying time of 15 minutes to 1 hour.
