Abstract

Dalam dunia pendidikan kolaborasi antar program studi sangatlah penting. Keterkaitan kepentingan satu sama lain sangatlah dibutuhkan untuk menunjang penelitian, dalam penelitian kali ini program studi teknik kimia FT UMJ membutuhkan suatu mesin pengiris ampas tahu dimana tingkat kesulitannya sangat tinggi dikarenakan ampas tahu memiliki kandungan kadar air 10% tetapi dengan tekstur bahan yang sangat lembek sehingga menjadi kendala dalam pengirisan. Untuk itu program studi Teknik Mesin FT UMJ dan UNTIRTA akan merancang bangun mesin pengiris ampas tahu, dimana ketebalan yang diinginkan sesuai kebutuhan pasar antara 3 – 5 mm. Mesin pengiris ampas tahu ini adalah mesin yang bekerja secara bolak-balik dengan menggunakan pisau stainess steel. Mesin seperti ini sangat membantu dalam efisiensi waktu karena menggunakan motor DC 12 volt 30 ampere dengan metode teoritis yang diaplikasikan dengan menggunakan software SOLIDWORK, dimana diperoleh hasil dari uji exsperimental dengan dua hasil yang berbeda sebagai perbandingan. Pada putaran low speed sebesar 1 kg ampas tahu terpotong selama 2 menit  dan high speed sebesar 1 kg ampas tahu terpotong dalam waktu 1 menit. Dengan hasil terbaik pada pengujian putaran high speed, ketebalan yang dihasilkan juga sesuai dengan yang dibutuhkan 3-5 mm.Kata kunci : mesin pengiris ampas tahu, pisau bolak-balik, motor DC 12 Volt

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

This study focuses on designing a touch-free door lock system based on Arduino, utilizing ultrasonic sensors, sound sensors, magnetic switches, and slot locks, following the Pahl and Beitz design methodology. The aim is to develop a reliable system that enhances convenience and reduces the need for physical contact with door locks. The results indicate that the ultrasonic sensor performs effectively in detecting distances, while the magnetic switch operates within a maximum reading range of 10 mm. However, the sound sensor demonstrated low accuracy, requiring multiple claps for successful detection. The findings suggest that the developed product functions as intended, though the limitations of the sound sensor highlight the need for further improvements to optimize precision and responsiveness.
