Abstract

In general, every livestock needs feed in the form of a mixture of livestock feed. The livestock feed fermentation process is currently phenomenal because it provides benefits that are felt by farmers. Maybe many people know the fermentation as a process of making supplement drinks only. It turns out not, the fermentation process can be used as an alternative to making high-quality livestock feed. In addition to being very simple to make, making feed by fermentation also saves time and money, because farmers are no longer busy with herding or grazing. This horizontal mixer machine has a capacity of 100 kg / Batch. In making this machine includes manufacturing processes such as: welding, grinding, drilling, bending, cutting torch or gas cutting, and non-permanent joints, namely nut and bolt joints. The components of the machine are: frame, tube, double screw, axle shaft, bossing, gear box, housing bearing, block bearing, pulley, v-belt, and electric motor. And then assembled and put together into a machine. From the above explanation, the following conclusions can be drawn: 1. Horizontal mixer machine with a tube diameter of 60 cm and a width of 90 cm, is capable of mixing 100 kg/batch of animal feed. 2. Horizontal mixer machine using a double screw produces a more homogeneous mixture compared to using the manual method.

Abstract

Using manual oil palm fruit harvesting tools requires a lot of energy and time, especially for trees with a height of more than 5 meters. This study aims to design and create an efficient, ergonomic, and environmentally friendly electric-based oil palm fruit harvesting tool. This system uses a DC electric motor controlled by a switch, with a sickle-shaped cutting blade driven by a transmission belt. The test results showed that the tool could cut oil palm bunches at 5-8 meters height with an average cutting time of 5-7 seconds per bunch. Power consumption was recorded at 150 Watts with a 24V 10Ah lithium battery power source.

Abstract

This study aims to analyze the performance of a fried onion draining machine designed for the needs of small-scale food industries. The machine operates using the principle of centrifugal force and is constructed with 304 stainless steel to ensure food safety and resistance to corrosion. Testing was conducted using variables such as rotation speed, draining time, and material capacity. Results show that the machine can reduce oil content in fried onions by 14.29% within 2 minutes, with a draining capacity of 50 kg per hour at 700 rpm. Energy efficiency achived was 35,49%, showing the potential for practical application of this machine in the UMKM environment. The use of this machine results in fried onions that are crispier, have a longer shelf life, and are processed more hygienically and efficiently. Further recommendations include design and operation system optimization to improve performance.

Abstract

This research aims to design and test the performance of a CNC-based mini milling machine as a lightweight milling solution at a relatively affordable cost. The research stage is carried out systematically, starting with the selection of concepts and proceeding through morphological table analysis, followed by the component manufacturing process, which utilizes CNC turning machines to ensure dimensional precision. After that, the main components were assembled, including aluminum tables, stepper motors, trapezoidal threads, DC motor spindles, and support frames that function to maintain structural stability. The tests focus on the stability of axis motion and the precision level of cutting light materials. The test results indicate that the CNC machine operates within acceptable tolerances, is stable enough, and precise for simple cutting applications, making it suitable for use in engineering education and small-scale production, with good operational efficiency.

Abstract

This article analyzes the durability of electrical energy in palm fruit cutter machines as an efficient and environmentally friendly innovation in the field of harvesting tools. The machine is designed using a 12V 15A DC motor that converts the rotary motion into translation through a crank slide mechanism, powered by a 35Ah battery. Tests were carried out on oil palm trees 3–5 meters high by monitoring power consumption and operating time. The results show that cutting thick fronds requires 15 Watts/minute, while thin ones require 11.25 Watts/minute. The effective operation duration reaches 1 hour and 52 minutes. Performance factors are influenced by battery condition, cutting load, transmission efficiency, and cutting tool design.

Abstract

The problem of plastic waste continues to increase and requires effective technical solutions through the recycling process. One of the crucial stages is enumeration, which aims to reduce the size of the material so that it can be easily reprocessed. This research aimed to design a plastic and composite polymer shredding machine with a capacity of 10 kg/h, featuring a simple construction, energy-saving capabilities, and suitability for both household and small industrial applications. The design process includes power requirement analysis, frame design, blade selection, and transmission system. The test results showed that the machine was able to produce plastic shreds of an average size of 5 mm with performance close to the target capacity. This machine has the potential to improve the treatment of plastic waste locally.

Abstract

Polymers are the result of monomer polymerization with a lower density than metals but a much smaller elastic modulus, making them less rigid and strongly affected by temperature. This study evaluates the performance of a laboratory-scale crushing machine for polypropylene blended with activated carbon at varying compositions. The machine employed carbon steel rotary blades driven by a 1 HP electric motor through a gearbox transmission. Results showed average crushing times of 3.5–4 minutes/kg. Pure polypropylene produced a 72% fine fraction, while adding 10% activated carbon reduced it to 65%. Crushing efficiency remained above 85%, demonstrating stable performance and feasibility for composite material applications.
