Abstract

Adanya industri pangan yang berada di Dukuh Rowobajul, Kelurahan Pojoksari, Kecamatan Ambarawa, Semarang yang mana memproduksi kerupuk kering pada proses pengirisannya masih dilakukan dengan cara manual, sehingga menyebabkan kapasitas produksi yang belum bisa memenuhi permintaan pasar. Oleh karena itu perlu solusi untuk meningkatkan kapasitas produksi kerupuk bawang. Metode yang dilakukan adalah penerapan mesin pengiris adonan kerupuk untuk memudahkan pembuatan dari kerupuk bawang dengan harapan dapat menggantikan proses manual yang memerlukan waktu yang lama menjadi waktu yang relatif lebih singkat. Kesimpulan dari pengabdian kepada masyarakata ini adalah penerapan mesin pengiris kerupuk bawang mampu memberikan manfaat kepada mitra, dnegan meningkatkan kapastas produksi kerupuk bawang.

Abstract

Abstract  Cycle Time is a matter that must be considered in production time, a good Cycle Time will support the targets that must be met, even if Cycle Time decreases, production will also increase and company turnover will also Increase. In the case study of PT Arisamandiri Pratama, one of its productions is in the form of AC parts, namely capillary pipes which still use a manual rotating table to rotate the pipe to be welded so that it is unable to reach the target of 800 parts / hour with an average Not Good product of 93 parts / day. The design of an inverter-based electric rotary table can reduce cycle time, but how much frequency will affect the results of a welding, not that the faster the welding process the better, the faster the welding will affect the vibration of the table machine which will have an impact on the welding results. By experiment the inverter frequency setting is expected to get a frequency value with maximum speed but no vibration on the rotation table, the frequency used is between 700 Hz to 1500 Hz with an interval of 100 Hz. The experimental results show that the best frequency is 1000 Hz, with a rotation speed of 16 rpm with a production capacity of 935 parts / hour with Not Good products of 59 parts / day or a decrease in Not Good products by 42.1% per day

Abstract

A compound fertilizer mixing machine (mixer) is a type of machine used to produce compound fertilizer. This fertilizer consists of a mixture of humus fertilizer, animal manure and humus soil. This machine is very important in its use as a mixer of different types of fertilizer ingredients, so as to produce a homogeneous mixture. The aim of this research is to design a fertilizer mixing machine that can be used by small and medium industries and farmer groups. In this design, consider the factors that influence the strength of the main components, such as the drive shaft, mixing blade, belt transmission system, machine frame, etc. This research was carried out in three stages, namely the load simulation stage on the drive shaft and stirrer blade to determine the safety factor. The second stage is calculations in the design of the main components of the machine. In the final stage, the process of making the machine and testing is carried out. The design of this machine was simulated using SOLIDWORK 20 software. The simulation results using SOLIDWORK showed a minimum FOS (Factor of Safety) value of 2.98 on the stirrer blade and the main shaft had met the safety factor. The test results of this fertilizer mixing machine have a capacity of 950 kg/hour.
