Abstract

The demand for engineers in Indonesia has not been met with the number of professional engineers working in their respective fields. This is partly due to the low interest in engineering among students. Therefore, various programs are implemented by the government and companies to be able to introduce, educate and change perceptions on the field of engineering. This research was conducted to propose a Corporate Social Responsibility (CSR) program in order to meet these objectives. The proposed program is an educational program in the form of a workshop on residential construction using miniature houses built of real construction materials as demonstration and learning tools. The program is aimed at high school students in accordance with the goal of increasing public interests and the number of potential engineers, particularly in the field of civil engineering. The validation process of the proposed program is done by distributing questionnaires to construction companies and high school students as stakeholders in the program's execution. The validation results show that the proposed program is quite attractive to construction companies and high school students, including those who are not interested in the engineering field. The program is also deemed feasible and able to meet the goal of developing students' interest in engineering

Abstract

3D printing is a manufacturing process widely used in the 4.0 Industry era. One of the concepts of 3D printing is to make prototypes, whether it is for industrial purposes or studying purposes. Knowing that a prototype is only needed in the early stages of any process, it is bound to be redundant in a short time; thus, the plastics used to prototype using the 3D printing technology are now labeled as waste. Since most plastics used for 3D printing are thermoplastics, they can be recycled to live another purpose. This research aims to design a crusher dedicated to processing 3D printing waste as the first step towards recycling these wasted materials. This step encourages students to comprehend the process of designing and manufacturing such equipment while also opening doors for the faculty towards recycling 3D printed plastics. The designing process consists of surveying the materials commonly used for 3D printing, calculating the machine elements, choosing the mechanism needed to destroy the material, and designing a model from the calculations. The outcome of the design is a device that can crush and destroy PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) plastics into pieces ready for recycling

Abstract

The need for a simple grid-connected inverter is increasing. The integration of a simple buck converter and a push-pull converter to be a grid-connected inverter is presented in this paper. The buck converter is controlled by a sinusoidal duty ratio to produce a series positive half-cycle of a sine wave. Then, the push-pull converter solves it to generate the complete sinusoidal output voltage and current. Moreover, grid synchronization works properly by sensing the grid voltage, which is then used as a reference voltage to connect the inverter to the grid successfully. The grid sees the inverter as a resistive load with a unity power factor. The total harmonic distortion (THD) of the grid current is 4.87% for the THD grid voltage of 2.07%.
