Design of Building Tools of Rubber Seeds Core and Separator from Rubber Seed Shells (Hevea Brasiliensis) with Mechanical Systems

Introduction

Rubber seeds (Hevea brasiliensis) are a byproduct of rubber plantations that are often underutilized. Each rubber seed contains a significant amount of vegetable oil, approximately 45.63%, making it a potential raw material for food oil. However, the hard rubber seed shells often become a barrier in the process of utilizing these seeds. This study aims to design tools that can break down and separate the core of the rubber seeds from the shell using an efficient mechanical system.

The Importance of Rubber Seeds

Rubber seeds are a valuable resource that can be used as a raw material for various products, including vegetable oil and biobriquettes. The use of rubber seeds can provide a significant economic benefit for entrepreneurs and contribute to increasing the productivity of the agricultural industry and processing rubber plantations. However, the hard rubber seed shells often become a barrier in the process of utilizing these seeds.

Design and Tool Function

The tools designed for this study use a single roller crusher system as a rubber seed breaker. The work process of this tool begins by inserting rubber seeds into the crusher, where the seeds will experience sufficient pressure to destroy the shell. Once crushed, the material will pass through a static sieve, which functions to separate the core of the rubber seeds from the shell. The device dimension of 1310 mm × 500 mm × 600 mm makes this tool easy to use and efficient in the separation process.

Analysis of Capacity and Results

The results of this study showed that the effective capacity of the tool reached 46.998%. However, there are challenges in the separation process, where the percentage of rubber seeds left behind reaches 17%. Of the total separation results, the rubber seed core was 31.17%, while the rubber seed shell reached 67%, with a loss of around 1.84%. The electric power consumption of this rubber seed breakdown is recorded at 7.43 kWh, which shows the energy efficiency of this tool in processing rubber seeds.

Tool Profitability

By conducting further analysis, it is known that the break-up point value of this tool can be achieved by processing 16,555,756 kg of rubber seeds per year. From the economic side, this tool is proven to be profitable, with a net present value (NPV) greater than zero, namely IDR 24,991,463.32 per year at an interest rate of 6%. In fact, at the experimental interest rate, NPV still shows a positive number of IDR 21,921,825,362 per year. This tool also shows a very promising internal rate of return (IRR), which is 42.468%.

Mechanical System Design

The mechanical system designed for this tool uses a single roller crusher system as a rubber seed breaker. The work process of this tool begins by inserting rubber seeds into the crusher, where the seeds will experience sufficient pressure to destroy the shell. Once crushed, the material will pass through a static sieve, which functions to separate the core of the rubber seeds from the shell. The device dimension of 1310 mm × 500 mm × 600 mm makes this tool easy to use and efficient in the separation process.
