Abstract

This research is motivated by the increasing gas emissions produced by industrial, automotive and household activities which mostly use fossil energy as an energy source. CO2 capture is introduced to the use of gasification technology in an effort to reduce CO2 emissions which are one of the causes of the greenhouse effect. The role of microwave is also introduced as an effort to increase thermal efficiency and increase production and quality of syngas and its role in reducing tar which is known to be high in biomass gasification. The utilization of water vapor is also clearly disclosed and its effect on syngas products, especially hydrogen gas. The role of the parameters that affect the gasification process is analyzed to see which variant has the best role in improving the quality and quantity of syngas. Research development opportunities are presented by looking at research gaps and future prospects

Abstract

Penelitian ini bertujuan untuk mengukur efektivitas penggunaan media pembelajaran basic electro pneumatic trainer dalam meningkatkan hasil belajar mahasiswa pada mata kuliah Hidrolik & Pneumatik di Politeknik Krakatau. Latar belakang penelitian ini didorong oleh pentingnya kompetensi praktis mahasiswa vokasi dalam menghadapi tuntutan industri modern, terutama pada bidang mekanika fluida. Metode yang digunakan adalah pra-eksperimen dengan desain One-Group Pretest-Posttest, melibatkan 30 mahasiswa semester IV Program Studi Teknologi Rekayasa Elektrikal Mekanik. Instrumen penelitian berupa tes pilihan ganda untuk mengukur kemampuan kognitif sebelum dan sesudah perlakuan.Hasil penelitian menunjukkan adanya peningkatan rata-rata nilai dari 63,3 pada pretest menjadi 83,8 pada posttest, dengan selisih 20,5 poin. Uji Wilcoxon menghasilkan nilai signifikansi 0,000 (<0,05) yang mengindikasikan perbedaan signifikan. Nilai rata-rata N-Gain Score sebesar 57% juga menunjukkan efektivitas pada kategori cukup. Kesimpulannya, penggunaan media basic electro pneumatic trainer terbukti dapat meningkatkan pemahaman konsep serta keterampilan mahasiswa secara signifikan. Temuan ini diharapkan dapat menjadi acuan bagi institusi pendidikan vokasi dalam merancang strategi pembelajaran yang lebih kontekstual dan aplikatif demi menghasilkan lulusan yang siap bersaing di dunia industri

Abstract

One emerging technology is the use of conveyor-based trash collection boats. This study aims to design and analyze the electrical system of a paddle conveyor—based on a DC motor and a linear actuator—on a trash collection boat as a means of improving the effectiveness of trash collection from the water’s surface. The research method employed a qualitative approach using case studies, with data collected through direct observation, interviews, and documentation of the trash boat prototype. The research results show that the integration of a DC motor as the conveyor drive and a linear actuator as the position controller produces a more stable and precise waste-lifting mechanism. A 24 VDC relay-based control system with limit switch interlock logic has been shown to improve system reliability and prevent motion conflicts and overtravel in the actuator. Functional testing showed that the entire system operates as designed, with rapid response to operating commands, stable conveyor speed, and accurate actuator movement to the upper and lower limits. Compared to previous designs, this research offers a safer, more adaptive, and more energy-efficient solution. Overall, the electrical system developed is capable of effectively supporting the operation of the trash boat and can serve as a foundation for the development of more modern water cleanup technologies. This research contributes to the design of an integrated control system that can be expanded to include current sensors, microcontroller-based control, and renewable energy support in subsequent development phases.
